An Emergency Tack Puller

One day I had to pull some tacks but had no tack puller at hand. An idea

came to me to use the kitchen spoon, and I found that it worked even

better than a regular tack puller. The ordinary kitchen spoon usually has

an edge sharp enough to get under any tack.--Contributed by H. D. Harkins,

A Puzzle with Figures

This puzzle is to arrange all the figures or digits, from 1 to

9 inclusively, in two rows, each containing all the digits, so that the

sum in addition as well as the remainder in subtraction will have nine

figures, in which all the digits are represented. There are several

solutions to the puzzle, and the following is one of them:

371294568 216397845

The sum of the foregoing numbers and the remainder, when the lower row

is subtracted from the upper, will both have nine figures and include all

the digits from 1 to 9.--Contributed by Walter Bennett, Detroit, Mich.

To Fasten Loose Table Legs

When legs of an ordinary table become loose and unsteady they may be

easily repaired as shown in the sketch. Nails do not hold well in such

places and glue will not stand much washing.

[Illustration: A Piece of Wire Bent around the Leg of a Table will Make

It Rigid]

The method of making the repair is to drill 1/8-in. holes through the

rails on each side of the leg and insert pieces of galvanized wire of

a size to fit the holes. After the wire is inserted, the ends are bent

over. The illustration clearly shows the repair.--Contributed by Edwin C.

Wright, Newport, Ky.

Washbasin Holder

[Illustration]

A piece of wire formed into the shape shown in the sketch makes a handy

hook to hold a washbasin when it is not in use. This keeps it out of the

way and out of the dirty water which might be thrown into the kitchen

sink.--Contributed by F. C. Althen, Anamosa, Iowa.

A Cleaner for Canvas Shoes

One of the most economical cleansers for canvas shoes is oxide of zinc.

Mix a small quantity of the powder with water, to the consistency of

thin paste, and apply it to the canvas with an old toothbrush, rubbing

it in thoroughly. Then set the shoes aside to dry before wearing

them.--Contributed by Katharine D. Morse, Syracuse, N. Y.

Ruling Blank Books

A special ruling for a blank book can be drawn by using a thin piece of

sheet metal or cardboard, cut as shown in Fig. 1, for a template. The

pencil is drawn along one edge of the cutout so that it will make lines

as shown in Fig. 2.

[Illustration: A Template Having Slots Cut for Drawing Special Vertical

and Horizontal Lines on Pages (Fig. 1, Fig. 2)]

If horizontal lines are required, cut notches on the edge for the location

of each line as shown. When the vertical lines are drawn, these notches

will mark the places for the horizontal lines.

How to Demagnetize a Watch

Quite often the attendants or a visitor to an electric-light plant

discovers after a few days that his watch is losing a half hour or more

a day by having become magnetized by the dynamos. In stations where the

old types of machines are still in use there is a great deal more danger

from what is called "stray" magnetic fields than in those where modern

machines are installed.

The jeweler demagnetizes a watch in the following way: He has a piece of

soft iron with an opening cut in its center of such shape and size as to

receive the watch, and with a fine wire wound about it. After the watch

has been placed in position, an alternating current, that is, one whose

direction is changing at regular intervals, is sent through the winding,

and thus a magnetic field is produced that also changes in direction

as the current reverses. The current is gradually reduced in value and

the magnetism originally possessed by the watch is removed. When an

alternating current is not available, a direct current may be used, its

direction being rapidly reversed by what is known as a "polarity changer."

Anyone can demagnetize his own watch, however, with very little trouble

and no expense by a much simpler method. Procure a piece of heavy linen

thread about 3 ft. long, attach one end of it to the ring of the watch,

hold the other end and turn the watch around until the thread is twisted

at least one hundred times. Now allow the thread to unwind, and as the

watch revolves, pass it back and forth near a powerful electromagnet.

The field magnet of a good-sized generator or motor will answer. The

machine should be in operation, or at least there should be a current

in the windings about the fields, when you attempt to demagnetize the

watch. While the thread is unwinding, and the watch moved in the magnetic

field, gradually withdraw from the magnet so that when the watch ceases

to revolve, it is just outside of the field.

Always be sure to keep the watch revolving while it is in the magnetic

field, otherwise the results will be very unsatisfactory, and more harm

than good may result.

A Pencil Holder

Procure a piece of paper, 7 in. long and 4 in. wide, and roll it one time

around a lead pencil, then coat the remaining surface of the paper with

glue. Roll this around the pencil and a tube is formed, which will hold

a pencil or even pieces of pencil down to 1/2 in. in length.--Contributed

A Poultry-Food Chopper

The illustration shows a handy device for cutting roots for food, and for

chopping and mixing stale bread, potatoes, peelings, refuse fruit, etc.,

for poultry. Any blacksmith can make the chopper at little cost. For the

cutting blades use two pieces of steel a little heavier than oil-barrel

hoops, each 1-1/2 in. wide and 8 in. long. Procure a 1/2-in. iron rod,

about 3 ft. long, bend one end in the shape of a spade handle and split

the other end for a distance of about 2-1/2 in.

[Illustration: The Chopper Consists of a Rod Handle to Which Blades are

Attached by Riveting or Welding]

Sharpen one edge of each blade and curve the metal slightly. Lay the two

blades together with the convex sides touching in the center and insert

them in the slit in the handle end. They are riveted or welded in place.

Heat and bend the blades at right angles.

Many of the materials mentioned for poultry foods may be chopped in an

ordinary pail having a strong bottom, but it is best to make a box, about

1-1/2 ft. square and with a plank bottom, for use with the chopper.

A Small Spring Hinge

Box covers or small doors that are seldom used can be supplied with a

small spring hinge as shown in the illustration. The hinge is made of a

piece of spring wire which is formed similar to a staple with a coil or

complete turn given to the wire in the center. It is attached by driving

the points, one into the door and the other into the casing.

[Illustration: The Shape of the Hinge, and the Manner of Attaching It to

Shoestring End

When the tips slip from shoelaces, new ones may be readily made of fine

wire. The wire is run through the end of the lace, Fig. 1, and the two

ends are twisted tightly together as shown in Fig. 2. This covers the end

of the lace and makes, a tip that is easily passed through the eyelets.

[Illustration: The Wire Prevents the Lace from Raveling and Makes a Tip

for Easily Entering the Eyelets (Fig. 1, Fig. 2)]

Threads on Wood Shafts

In model making it is quite necessary at times to have threads on a wood

shaft. These can be made quite satisfactorily by coiling a wire around the

shaft where the threads are wanted, and driving the ends into the wood.

[Illustration: The Wire Forms a Thread That in Many Instances is Quite

Serviceable for Model Making]

A Glass Breaker

After cutting glass, and especially where a small strip is to be removed,

the part must be broken away in small pieces. The accompanying sketch

shows a very useful tool for this purpose. The tool is made of a piece of

metal having a bolt fastened to it at one end whose nut can be adjusted

to the thickness of the glass.

[Illustration: The Nut is Set to the Thickness of the Glass and Used to

Break Pieces Away]

Old discarded blueprints can be made white and used

for sketching by dipping them in a solution of soda

gallon of water.

Wood Postal Cards

The card consists of three pieces, or three-ply, veneer. The grain of

the outside veneer runs lengthwise, while that of the inside piece runs

crosswise. This makes the card straight and keeps it from breaking.

For the inner section, walnut, which may be had as thin as 1/64 in.,

or any thin straight-grained veneer may be used. Two pieces of veneer,

about 3-3/4 in. wide and 6 in. long; one piece, 6 in. wide and 3-3/4 in.

long,--the length being with the grain of the wood--and two blocks of

wood, known as cauls, of the same size or a little larger, and about

7/8 in. thick, are required.

The veneer is laid flat on a board and cut with a sharp knife or fine

saw along the edge of a ruler. The three pieces are glued together in the

following manner. Use ordinary hot glue, not too thin, but thin enough to

run freely from the brush. The glue is applied evenly on both sides of the

inner piece only, and this is then stood on edge until the glue chills.

Then the cauls are heated. This is best done on a stove, or on stove lids

over a gas fire. While the blocks are being heated, put one veneer on

either side of the middle piece, and a piece of thin paper on each side

to keep the glue from the cauls. A hand screw or vise should be opened

to almost the distance required. One of the cauls is now laid flat, the

veneers upon it and the other caul on top. This should be done quickly.

Then clamp the whole firmly together. While the full pressure is only

needed for about two hours, the pieces should be allowed to dry between

the cauls for, say, a day or two, so that they will keep straight. The

size of the finished card is 3-3/8 in. by 5-1/2 in. It is cut and planed

to size while lying flat on a board, the plane being pushed along on its

side on the bench top. To dress or clean, clamp one side to the bench.

While a scraper blade may be used to advantage, it is not essential, as a

block of wood and sandpaper will do. The thinner it is dressed the better.

The sharp edges should be removed with sandpaper. The writing on a wood

card is not done in the ordinary manner, as the ink would run. The surface

must be prepared, which also gives a finish to the wood. Melt some wax or

paraffin in a suitable vessel and cover the surface of the wood, using

a brush or rag. The lines for the address on one side are then drawn,

and the writing is done with a hard lead pencil. When through writing on

one side, cover it with some strong aniline stain. (Aniline, dissolved

in hot water, commonly known as water stain and used especially to stain

mahogany, is the right kind.) Do not remove the wax that was raised by the

pencil point. Brush the stain over until the whole side is covered. When

dry, repeat on the other side. In about an hour the wax may be scraped off

with a dull scraper or some other dull instrument. After every particle

of wax has been removed, the card is given a good rubbing with a clean,

soft rag. It is well to protect the hands as well as the table during the

process.--Contributed by Chas. Schapmeier, Baltimore, Md.

Fastening Screws in Tile and Brick Walls

A simple way to fasten screws in tile or brick walls is to drill holes,

not too large, for the screws, then tear up some paper, wet it and make

a pulp. Pack this pulp tightly in the hole and turn in the screws. The

screws will stand a great deal of strain.--Contributed by John Thomas,

Brantford, Ont.

Shoe Pull Made of an Eyelet

The pulling-on strap at the back of a shoe often comes loose, or pulls

out, and even if it does not, the trousers will sometimes catch on it

if the strap is not tucked inside of the shoe. A very simple way to

overcome these troubles is to remove the straps and substitute eyelets.

A buttonhook will then serve admirably in pulling the shoe onto the foot.

Holder for a Set of Sadirons

A very attractive holder for a set of sadirons and their handle can be

made as shown in the illustration, although the design may be changed if

desired. The holder consists of a shield-shaped back, which is fastened to

the wall in a convenient place and has a shelf with openings for the irons

attached to it. The shelf is made in two pieces, the bottom part being

covered with a heavy piece of tin while the upper is cut out to receive

the irons.

The irons are placed on the upper piece in such positions that they will

be attractively displayed and evenly located, and then a lead-pencil mark

is drawn around their base. Openings are cut in the wood on these marks

and the board fastened on top of the tin-covered shelf. An ordinary brass

bracket is used in the center beneath the shelf, to keep it from sagging.

[Illustration: An Ornamented Bracket Shelf for Holding a Complete Set of

Sadirons and Their Handle]

The shield is fastened to the wall with two screws, over which two

brushed-brass, diamond-shaped pieces are fastened with large brass tacks,

to cover the screw heads. The corners of the shield may be ornamented

with brushed-brass designs, and the wood finished as desired. The irons

can be set in the holder while hot without fear of burning any part, and

they will present a very neat appearance.--Contributed by G. E. Martin,

A Garden Roller

A garden roller for digging the earth and crushing clods is easily made

of the following material: One round piece of wood, 10 in. in diameter

and 18 in. long; two pieces of wood, each 56 in. long, 2-1/2 in. wide and

1-1/4 in. thick; one piece, 21 in. long, 2 in. wide and 1 in. thick; two

1/2-in. lag screws, 6 in. long, and a quantity of 8-penny nails.

[Illustration: A Roller for Crushing Clods and Digging the Earth in Garden

Making]

The short piece of wood is fitted between the two long pieces with

tenon-and-mortise joints to serve as a handle at one end and the roller is

fastened between the side pieces at the opposite end to revolve on the lag

screws. The nails are driven into the roller so that they project about

1 in.

A Substitute for Glaziers' Points

Ordinary small staples make good substitutes for glaziers' tacks. The

points of the staples should be drawn apart slightly, as shown at A, to

give them a greater holding area and at the same time make them easier

to drive. These points seem to hold the glass better than the regular

glaziers' points, consequently the putty will not crack and loosen, and

renewing is avoided.--Contributed by Edward Sieja, Chicago.

Water-Heating Coil in a Furnace Pipe

[Illustration]

The accompanying sketch shows a plan I adopted for conserving the waste

heat from my furnace. I found that I was able to put a coil into the smoke

pipe, which was about 8 in. in diameter, and thus heat water for domestic

purposes. It will be seen that the coil is spiral in shape rather than

cylindrical, as the latter would leave a free passage up the center and

therefore would not bring enough gases into contact with the coil.

In addition to this coil I have a gas heater near the tank which is used

only in case the demand for hot water exceeds the capacity of the coil,

which is naturally not as efficient per unit of length as one directly

within the firepot would be. It has the advantage of not absorbing heat

which should go to make steam, but only that which would otherwise be

wasted. The heating surface of the coil is much greater than would be

possible within the firepot, which in a measure compensates for its lower

efficiency.--Contributed by W. E. Morey, Chicago.

A Homemade Marking Gauge

[Illustration]

A 3/8-in. bushing is turned into the side outlet of a 3/8-in. tee. The

bushing is then tapped to receive a 7/16-in. wing bolt. A tight-fitting

wood plug is driven into the throughway of the tee and the ends ground off

flush on the emery wheel. A slot, 5/16-in. square, is then cut through the

wood plug just under the bushing. Two pieces of flat steel, each 1/4 in.

wide by 1/8 in. thick and 1/8 in. longer than the tee, are fitted in the

slot cut in the plug as shown in the sketch. The outer end of each piece

is bent at right angles and sharpened. After the points have been drawn

out to the right distance, the wing bolt is turned to hold them in that

position.--Contributed by C. Molloy, Philadelphia, Pa.

Protecting Brush Handles from Paint

A very efficient method to prevent paint from running down on a paintbrush

handle and on the hand is to cut a hollow rubber ball in half, Fig. 1,

make a hole in the center to fit the brush handle and attach it as shown

in Fig. 2. One ball will fit up two brushes. The cup shape catches the

paint and prevents it from getting on the handle.--Contributed by O. H.

A Tie-Pin Holder

Having lost several tie pins by theft or by their falling out I made a

little device to securely hold the pin in the tie. This device makes it

almost impossible to pull the pin out and it cannot be lost accidentally.

The device is made of a small safety pin, bent as shown, with one arm, A,

longer than the other, B. The arm A is put on the pin first or upward, and

attached as shown at C. When pulling on the tie pin the arms of the holder

tend to draw together and clamp it on the pin.--Contributed by Robert C.

Hulling Walnuts

When gathering my winter supply of walnuts, I found that they could not

be hulled readily by hand. Not knowing of any machine designed for the

purpose, I tried running them through a corn sheller and found it to do

the work nicely. The sheller not only hulled them, but separated the nuts

from the hulls, the nuts being carried out through the cob opening and

the hulls dropping through the grain spout.--Contributed by Irl R. Hicks,

How to Make a Small Vise Screw

Procure an ordinary lag screw, as shown in Fig. 1, cut off the pointed

end and file the threads into the shape shown in Fig. 2. A hole is

drilled through the head and a handle put in, as shown in Fig. 3. This

makes a good substitute screw when the original screw for a small vise is

broken.--Contributed by James M. Kane, Doylestown. Pa.

A Medicine-Spoon Holder

When a dropper is not at hand it is difficult to drop medicine in a spoon

Sweeping the corners of steps is one of the greatest difficulties of

the housewife, or others who have a number of stairs to sweep. I have

longer and newer the better, and cut the straws off diagonally across the

sweeping edge. The pointed part will easily clean out the corners in steps

or in a room.--Contributed by W. A. Stamaman, Berlin, Ontario.

Removing a Cork from a Bottle

A cork that has been pushed into a bottle accidentally or otherwise can

be easily removed in the following manner: Tie several knots in one end

of a string to form a large cluster and drop it into the bottle, holding

on to the other end of the string. Turn the bottle over so that the cork

will fall to the opening in the neck, then pull on the string. The cluster

formed by the knots at the end of the string will easily draw out the

cork.--Contributed by Frank Hart, Chicago, Ill.

Tacking a Screen on a Frame

[Illustration]

Screen wire is very difficult material to fasten on a frame so that it

becomes taut. To make it taut and even drive the tacks as follows: First

tack the screen on one side of the frame, taking care to leave no slack

between the tacks, which should be about 1 ft. apart. Fasten the opposite

side by stretching the screen with one hand and with the other place the

tack through the meshes and push the point as far as possible toward the

outer edge of the screen frame as shown in the sketch. Drive the tack so

that it will enter the wood straight, which will draw the screen taut.

After having thus fastened the screen to two opposite sides of the frame

with tacks 1 ft. apart, other tacks are driven in midway between the first

ones, stretching the screen and driving the tacks as before described,

until a sufficient number of tacks are driven into either side. Then both

ends are attached in the same manner.--Contributed by Bertram S. Barnes,

Safety Tips on Chair Rockers

Some rocking chairs are so constructed that when the person occupying it

gives a hard tilt backward, the chair tips over or dangerously near it.

A rubber-tipped screw turned into the under side of each rocker, near the

rear end, will prevent the chair from tipping too far back.

Portable and Folding Bookcase or Closet

Two packing boxes hinged as shown and fitted with casters make a very

convenient portable closet. It can be folded flat against a wall or fitted

into a corner. If furnished with shelves, it can be used as a bookcase or

tool closet, and when fully opened, it makes a handy workbench.

Two projecting strips are fitted on the inside of one box so as to fit

tightly against the inner top and bottom surfaces of the other box, to

increase the rigidity of the box when closed. The addition of casters

makes the opening, closing and pushing about very easy. An ornamental hasp

or lock can be fitted if desired.

An Alarm for a Sleepwalker

A little girl in our family would walk in her sleep and it caused us

no little worry lest she might leave the house without our knowing it.

I therefore rigged up an alarm device to ring a bell should she leave

the room. The device consisted of a bell and battery in a circuit, and

a switch which was attached to one door casing. A string was stretched

across the doorway and attached to the switch lever in such a manner

as to pull it closed when the string was pushed through the doorway

opening.--Contributed by J. Woodburn, Toronto, Canada.

A Kraut and Root Grinder

The grinder is intended mainly for chopping cabbage when making

sauerkraut, but it is also of much service in grinding vegetables and

roots to be cooked for poultry.

[Illustration: The Grinder will Easily Reduce Cabbage Heads to Bits

Suitable for Sauerkraut]

The base A is made of a plank, at least 1 ft. wide and 4 ft. long, with a

9-1/4 by 9-1/2-in. hole cut in the center. The grinding part, or cylinder,

is made of wood, 3 in. in diameter and 9 in. long, with 8-penny nails,

spaced 3/16 in. apart, driven partly into it and then cut off so as to

leave 1/4 in. projecting. The cylinder is turned by means of a crank

attached to the end of the shaft.

A hopper, B, is constructed, 4 by 9-1/2 in. inside measurement at the

bottom, and as large as necessary at the top. A space is provided at

the bottom as shown to receive the concave C, which consists of a 1-in.

board, 3 to 4 in. wide and 9 in. long, with nails driven in and cut off

as described for the cylinder.

The hopper is securely fastened on top of the baseboard and over the

cylinder. The concave is slipped into place and held with wedges or by

driving two nails in just far enough to fasten it temporarily. The concave

can be adjusted for grinding the different vegetable products, or replaced

at any time with a new one.

The ends of the base are supported on boxes, or legs may be provided if

desired. When grinding cabbage, cut the heads into quarters and remove the

hearts. Press the cabbage on the cylinder and turn the crank. Fine bits

of cabbage, suitable for sauerkraut, will be the result.--Contributed by

Opening for Air at the Top of a Shade

Procure an extra long shade and cut two openings in the end to be used at

the top. The openings may be cut square or ornamental as desired, leaving

a strip at each side and one in the center. These strips are reinforced

by gluing on some of the same material as the shade or pieces of tape.

[Illustration: When the Shade is Pulled Down the Openings Coincide with

Hose Attachment for Watering Window Plants

The window garden of the house has its watering difficulties which one

owner overcame in a neat and handy manner. A hose on a weighted reel was

attached to the joists in the basement under the floor near the window

flower pots. The weight on the reel kept the hose wound on it and the

nozzle end which projects through the floor is large enough to hold it

from passing through the hole bored for the hose. A long stem valve was

provided with the wheel attached above the floor for turning the water on

and off.

[Illustration: The Hose is Automatically Run on a Reel by a Weight beneath

the Floor]

When the plants need a shower all that is necessary is to draw the hose

nozzle up and turn on the water. The hole for the hose and the valve wheel

can be located close to the wall under the flower tray where they will

scarcely be seen.

Removing Paint from Glass

Paint may be easily cleaned from glass by using a 50-per-cent solution of

acetic acid. The acid should be heated and applied with a cloth. The hot

acid will not hurt the hands or fabrics, nor the glass, but should be kept

from children who might drink of it. The solution is made of commercial

acetic acid and heated by adding hot water. The acid is inexpensive and

can be purchased at any local drug store.

To Prevent Baking Ovens from Scorching

A good method to prevent baking ovens from scorching or burning pastry

is to sprinkle a mixture of sand and salt on the bottom where the pans

are placed. This affords a way of radiating the heat evenly. The mixture

also absorbs fruit juices, which may be spilled in the course of cooking.

The covering is easily changed, which keeps the oven clean. The best

proportion is half salt and half sand.

Horn Candle Sconce

The person who cares for things unusual will find the candle sconce made

of a cowhorn a suitable fixture for the den. A well shaped and not too

large cowhorn is selected, and prepared by first partly filling it with

paper, packed in tightly, then filling it to the top with plaster of

Paris, in which a candle socket is formed.

The bracket is made of strips of metal, formed as shown and riveted

together where they touch each other, the back piece being fastened with

screws to a wall board. The metal may be brass or copper and finished in

nickel, antique, bronze, or given a brush finish. The wooden wall piece

can be finished in any style desired.

How to Make a Copper Stencil for Marking Laundry

A stencil suitable for marking laundry may be easily made as follows:

First procure a small sheet of "stencil sheet copper," about 1 in. wide

and 4 in. long. Dip this sheet of copper in a vessel containing some

melted beeswax, so that both sides will be evenly covered with a thin

coat of the wax when it cools. The design--name, monogram or figure--that

is wanted in the stencil should now be drawn upon a piece of thin white

paper, the reverse side of the paper blackened with graphite, and then

laid on the stencil plate with the design in the center of the plate,

whereupon the design is lightly traced with a blunt point on the thin wax

coating. After the paper is removed, trace the design on the wax surface

with a pointed instrument, but not completely, the lines being broken at

more or less regular intervals, to form "holders" so that, after etching,

the design cannot fall out.

Next lay the stencil in a small shallow dish and pour a small quantity of

fresh nitric acid over it. Keep the air bubbles removed from the surface

by means of a piece of soft feather. The design will be eaten away in a

very short time, where the wax has been removed, and this may be readily

observed by holding the stencil plate up to the light. The acid should

then be rinsed off with water, and the wax removed by heating and wiping

it off with a cloth. The stencil may be given a final cleaning in a dish

of benzine or gasoline, which will remove any remaining wax.

A Brass Pin Tray

A novelty pin tray can be easily made of a piece of No. 24 gauge sheet

brass or copper, 5 in. in diameter. The metal is annealed and polished

with fine emery cloth, which is given a circular motion to produce a

frosted effect. The necessary tools are a 1-in. hardwood board with a

2-1/2-in. hole bored in it, and a round piece of hard wood, 1-7/8 or 2 in.

in diameter, with the ends sawn off square.

[Illustration: The Former and Method of Using It to Produce a Wrinkled

Edge on the Tray]

Place the sheet metal centrally over the hole in the board and set one

end of the round stick in the center of the metal. Drive the stick with a

hammer until a recess about 1 in. deep is made in the center. The edge of

the metal will wrinkle up as shown in the sketch. It is scarcely possible

to make two trays alike, as the edge almost invariably will buckle in a

different manner.--Contributed by F. Van Eps, Plainfield, N. J.

A Homemade Exerciser

A weight machine for exercising the muscles of the arms is easily

constructed by using two screw hooks, 5 in. long, and two small pulleys,

2-1/2 in. in diameter. An awning pulley can be used for this purpose.

The hole at the top of the hanger will allow the pulley to freely turn

at almost any angle. A paving brick or a piece of metal can be used as a

weight for each rope.--Contributed by Sterling R. Speirs, St. Louis, Mo.

A Book Covering

New books can be quickly and neatly covered to keep them clean by cutting

a paper large enough to cover the back and sides when the book is closed,

allowing 1 in. extra at each end to be turned over the front and back

edges, then pasting on corners cut from used envelopes. The paper jacket

can be slipped on or off easily when the book is opened, and it will keep

a new cover clean while the book is being handled.--Contributed by Dr.

John A. Cohalan, Philadelphia.

A Tilting Inkstand

An ink-bottle stand, that can be tilted or adjusted so that the pen will

always be filled with a sufficient quantity of ink even when little of

it remains in the bottle, as shown in the sketch, can be easily made by

the amateur. The base may consist of a square piece of sheet brass, which

has soldered or riveted to its center two pieces of spring brass, placed

crosswise and bent upward so as to form clips to hold the bottle firmly.

The legs are made of two lengths of wire, of sufficient stiffness, and

are shaped to form holders for lead pencils and penholders. One pair of

the legs may be soldered to the brass plate and the opposite side of the

latter rolled over the other pair so as to allow them either to stand

upright or be depressed in order to tilt the stand, when the ink supply

in the bottle gets low.

for a Small Supply of Ink]

A Ring Trick

The trick to be described is one of the simplest and at the same time

one of the most effective, and but little "make-ready" is required to

perform it. The magician, while sitting in a chair, allows his hands to

be tied together behind the back of the chair. A ring is placed between

his lips which he claims to be able to slip on his finger without untying

his hands. This, to the audience, seems practically impossible, but it is

easily accomplished.

A screen is placed in front of the performer before the trick is started,

so that the audience will not see how it is done. As soon as he is hidden

from view, he tilts his head forward and drops the ring in his lap. He

then allows the ring to drop to the seat of the chair between his legs.

The chair is tilted backward slightly, and he raises himself to allow the

ring to slip to the back part of the chair seat, where he catches it in

his hands and slips it on the finger. Any one finger may be mentioned, as

he can slip the ring as readily on one as on another. Use a leather-bottom

chair, if possible, as the least noise will then be made when the ring is

dropped.--Contributed by Abner B. Shaw, N. Dartmouth, Massachusetts.

Removing Old Putty

A very effective way to remove old putty from window panes or other

articles is to apply a red-hot iron, as follows: The iron should be made

of a broken file or cold chisel and the point heated quite hot. This

is run over the surface of the putty, which will crack and fall off. Be

careful not to let the hot iron touch the glass, as the heat may cause

the latter to break.

How to Make a Water Wheel

The materials used in the construction of this water wheel are such as

the average amateur mechanic may pick up or secure from a junk pile. The

drawings in Fig. 1 clearly show the way the wheel is built. The nozzle,

Fig. 2, is made of pipe and fittings and is adjustable to concentrate

the stream so as to get the full efficiency of the weight and velocity of

the water. The cap on the end of the nipple is drilled to receive the pin

point filed on the end of the 1/4-in. rod. The parts of this nozzle are

a 1/2-in. tee, connected to the source of water supply; a plug, drilled

to snugly fit the 1/4-in. rod, and fitted into one end of the straight

part of the tee; and a 1/2-in. nipple of sufficient length to make the

dimension shown in the sketch. The nipple has a long thread to receive two

1/2-in. locknuts, which clamp the nozzle to the sheet-metal covering, as

shown in Fig. 1.

[Illustration: Details of the Water Wheel (Fig. 1)]

The buckets, Fig. 3, are formed of some easily melted, but not too soft

metal alloy which can be cast in plaster molds. They are attached with

rivets to the circumference of 1/16-in. thick sheet-metal disk of the

diameter given in Fig. 1. This disk is fastened to a 1/4-in. shaft, 6 in.

long, with two collars, one on each side of the disk, both being riveted

to the disk and pinned to the shaft. The bearings AA are made of 3/4-in.

pipe, each 2-1/4 in. long. Long threads are cut on these to turn through

the two 3/4-in. waste nuts BB, which provides a way to adjust the buckets

centrally with the stream of water, and to take up any side motion. The

pipe is babbitted and drilled for oil holes. The runner or wheel must

be well balanced, as the speed will be from 2,000 to 2,500 revolutions

per minute with ordinary city pressure. In balancing the wheel, instead

of adding an extra weight, a part of the disk is filed out on one edge.

The inclosing sides are made of wood--cypress preferred--having the

dimensions given, and two 7/8 by 1-1/2-in. pieces are attached to the

bottom outside surfaces for mounting the wheel. The curved part is covered

with galvanized sheet metal.

[Illustration: (Fig. 2, Fig. 3)]

The drawing shows a wheel of small diameter, but having considerable

power. Greater power may be obtained by increasing the size of the jet

and the diameter of the wheel, but the use of too many buckets results in

decrease of power. One bucket should be just entering the stream of water,

when the working bucket is at a point at right angles to the stream. The

water should divide equally exactly on the center of the bucket and get

out of the way as soon as possible. Any stagnant water in the case, or

dead water in the bucket, is detrimental to the power. A free exit for

the water is made at the bottom of the case, as shown.

[Illustration: Metal Casing Instead of Wood (Fig. 4)]

The construction of the case may be varied and, instead of wood, metal

sides and frame may be used. Where the builder cares to make a more

substantial wheel and has access to a foundry, the metal parts can be made

as shown in Fig. 4. The parts are in this instance fastened together with

machine screws. Patterns are made and taken to a foundry for the castings,

which are then machined to have close fitting joints.--Contributed by R.

H. Franklin, Unnatosa, Wis.

An Interesting Experiment

Take an ordinary board, 2 or 3 ft. long, such as a bread board, and place

it on the table so that about one-third of its length will project over

the edge. Unfold a newspaper and lay it on the table over the board as

shown in the sketch. Anyone not familiar with the experiment would suppose

the board could be knocked off by hitting it on the outer end. It would

appear to be easy to do, but try it. Unless you are prepared to break the

board you will probably not be able to knock the board off.

[Illustration: Striking the Board]

The reason is that when the board is struck it forces the other end up

and the newspaper along with it. This causes a momentary vacuum to be

formed under the paper, and the pressure of the air above, which is about

15 lb. to the square inch, prevents the board from coming up. This is an

entertaining trick to play at an evening party, and also makes a simple

and interesting school experiment.

Ironing-Board Holder

An ironing board that had been used on two chairs was cut off square on

one end and a piece of heavy sheet metal cut and bent into the shape shown

in Fig. 1. The square end of the board was fitted into the socket formed

by the sheet metal. After attaching the socket to the wall with screws the

board was easily put in place as shown in Fig. 2. The brace is hinged to

the under side of the board.--Contributed by L. G. Swett, Rochester, N. Y.

How to Make a Water Motor By Edward Silja

After making several different styles of water motors I found the one

illustrated to be the most powerful as well as the simplest and most

inexpensive to make. It can be constructed in the following manner: A

disk, as shown in Fig. 1, cut from sheet iron or brass, 1/16 in. thick

and 9-3/4 in. in diameter, constitutes the main part of the wheel. The

circumference is divided into 24 equal parts, and a depth line marked

which is 8-1/4 in. in diameter. Notches are cut to the depth line, similar

to the teeth of a rip saw, one edge being on a line with the center of

the wheel and the other running from the top of one tooth to the base of

the preceding tooth.

[Illustration: Metal Disk with a Saw-Tooth Circumference That Constitutes

the Main Body of the Wheel (Fig. 1)]

A 1/4-in. hole is drilled in the center of the disk and the metal

strengthened with a flange, placed on each side of the disk and fastened

with screws or rivets. A 1/4-in. steel rod is used for the shaft.

The cups, or buckets, are shaped in a die which can be cast or built up

of two pieces, as desired. Both of these dies are shown in Fig. 2. The

one at A is made of two pieces riveted together.

[Illustration: Two Ways of Making the Dies to Shape the Sheet-Metal Water

Cups (Fig. 2)]

If a foundry is near, a pattern can be made for a casting, as shown at B.

The die is used in the manner shown in Fig. 3. A strip of galvanized metal

is placed over the depressions in the die and a ball-peen hammer used to

drive the metal into the die. Cups, or buckets, are thus formed which are

soldered to the edge of the teeth on a line with the center of the disk,

as shown in Fig. 4. As there are 24 notches in the disk, 24 cups will be

necessary to fill them.

[Illustration: The Sheet Metal is Placed on the Die and Then Hammered into

Shape (Fig. 3)]

The cups are made in pairs or in two sections, which is a better

construction than the single cup. The water from the nozzle first strikes

the center between the cups, then divides and produces a double force.

[Illustration: The Water Cups are Fastened to the Teeth on the Metal Disk

with Solder (Fig. 4)]

When this part of the work is finished it is well to balance the wheel,

which can be done by filing off some of the metal on the heavy side

or adding a little solder to the light side. This will be necessary to

provide an easy-running wheel that will not cause any unnecessary wear on

the bearings.

The housing for the wheel consists of two wood pieces, about 3/4-in. thick

and cut to the shape shown in Fig. 5. Grooves are cut in one surface of

each piece, to receive the edges of a strip of galvanized metal, as shown

at A. The grooves are cut with a specially constructed saw, shown in Fig.

6. It consists of a piece of wood, 6 in. long, 1-1/2 in. wide and 1/2 in.

thick, the end being cut on an arc of a circle whose diameter is 10 in. A

piece of a broken hacksaw blade is fastened with screws to the curved end.

A nail is used as a center pivot, forming a 5-in. and a 5-3/4-in. radius

to swing the saw on in cutting the groove. After inserting the strip of

galvanized metal, A, Fig. 5, the sides are clamped together with bolts

about 3-1/4 in. long.

[Illustration: The Housing for the Wheel with a Connection to Attach the

Motor on an Ordinary Faucet (Fig. 5)]

[Illustration: Construction of the Saw for Making the Groove to Receive

the Metal Strip in the Sides (Fig. 6)]

A piece of pipe, B, Fig. 5, having an opening 3/8-in. in diameter, is

soldered onto the metal strip A. An ordinary garden-hose coupling, C, is

soldered to the end of the pipe.

A bearing, D, shaped as shown, is fastened to one of the wood sides with

screws, the wheel shaft is run into it, and the parts assembled. A wheel,

either grooved or flat, 2-1/2 or 3 in. in diameter, is placed on the

shaft. The hose coupling makes it easy to connect the motor directly to

the water faucet.

An Application for Small Wounds

Pure wintergreen oil makes a good local application for all small wounds,

bites, scratches, abrasions, etc. There is no germ or microbe, animal or

vegetable, dead or living, that can withstand this oil, and at the same

time it is not injurious to living tissues. A few drops gently rubbed in

where there is apt to be any infection is sufficient.

An infection always follows the wound of a bullet or the scratch of a

brass pin, with irritation extending up the limb or part threatening

tetanus or lockjaw. These symptoms are manifested by spasmodic pains which

shoot upward, but are quickly subdued, if the oil is applied along the

track of the pain or infection. This oil is equally effective when locally

applied to tendons or ligaments which have been unduly strained.

An ounce of the pure oil does not cost much, and it should be kept in

every shop and household. If 5 or 10 per cent of olive oil is added to it,

the oil will have more body and will last longer.--Contributed by Dr. E.

R. Ellis, Detroit, Mich.

Cores for Use in Babbitt Metal

It is often necessary in making things of babbitt metal to core out some

of the parts. A very good core is made of common salt and glue. Mix just

enough of the glue into the salt to make a stiff paste, which is then

formed into the desired shape or molded in a core box and allowed to

harden. This kind of a core can be removed from the casting by soaking

it in warm water, which will dissolve the salt and leave the desired

hole.--Contributed by H. F. Hopkins, N. Girard, Pa.

How to Build a Wind Vane with an Electric Indicator

Quite often it is practically impossible to ascertain the direction of

the wind by observing an ordinary wind vane on account of the necessity

of locating the vane at such a height that it may give a true indication.

By means of the device shown in Fig. 2, the position of the vane may be

determined without actually looking at the vane itself and the indicating

device may be located almost anywhere and independently of the position

of the wind vane.

[Illustration: Fig. 1--The Diagram of a Wheatstone Bridge Which Shows the

Points of Contact So Placed That a Balance is Obtained]

The principle upon which the device operates is that of the Wheatstone

bridge. The position of the moving contact A, Fig. 1, is controlled by

the wind vane. This contact is made to move over a specially constructed

resistance R, Fig. 2. A second movable contact, B, is controlled by the

observer and moves over a second resistance, identical with that over

which the contact A moves. These two resistances are connected so as to

form the two main branches of a Wheatstone bridge; the points A and B are

connected to the current-detecting device, which may be a galvanometer or

telephone receiver, and current is supplied by a number of dry cells.

[Illustration: Fig. 2--The Weather Vane with Resistance Coil, and Diagram

of Indicator Which is Identical with That of the Vane]

In order to obtain a balance--that is, no current through the

receiver--the points A and B must occupy corresponding positions on their

respective resistances. If the two resistances over which the points A

and B move are mounted in the same position with respect to the cardinal

points of the compass, then the points themselves will always be in

the same position with respect to the cardinal points when a balance

is obtained. The arrow head on the wind vane and the point A are made

to occupy corresponding positions, and hence the position of the point

B, when no current passes through the receiver, is an indication of the

direction in which the wind vane is pointing.

The principal parts in the construction of the device are shown in the

illustration, and the following description of their construction may be

of interest to those who contemplate building the indicator.

Procure two pieces of 1/16-in. hard rubber, 1-1/2 in. wide by 24 in.

long. Clamp these, side by side, between two boards and smooth down their

edges and ends, and then file small slots in the edges with the edge of

a three-cornered file. These slots should all be equally spaced about

3/32 in. apart. Have the pieces clamped together while filing the slots

and mark one edge top and one end right so that the pieces may be mounted

alike. Now procure a small quantity of No. 20 gauge bare manganin wire.

Fasten one end of this wire to one end of the pieces of rubber by winding

it in and out through three or four small holes and then wind it around

the piece, placing the various turns in the small slots that were filed

in the edges. After completing the winding, fasten the end just as the

starting end was attached. Wind the second piece of rubber in a similar

manner and make sure to have the length of the free ends in each case

the same. Obtain a cylinder of some kind, about 8 in. in diameter, warm

the pieces of rubber by dipping them in hot water, bend them around the

cylinder and allow them to cool.

A containing case, similar to that shown in cross section in the upper

portion of Fig. 2 should now be constructed from a good quality of tin or

copper. The inside diameter of this case should be about 1 in. more than

the outside diameter of the resistance ring R, and it should be about

3 in. deep. The top C may be made curved as shown in the illustration, and

should be fastened to the case proper by a number of small machine screws.

The base of this case may be made so that the whole device can be mounted

on the top of a pole.

Mount a piece of 1/4-in. steel rod, about 1/2 in. long, with a conical

hole in one end, in the center of the bottom of the case as shown by M.

A number of supports, similar to the one shown, should be made from some

1/4-in. hard rubber and fastened to the sides of the case, to support the

resistance ring. The dimensions of these supports should be such that the

ends of the piece of rubber, forming the ring, are against each other when

it is in place. The upper edge of the ring should be about 2 in. above

the bottom of the case.

Next, mount a piece of brass tube, D, in the exact center of the top and

perpendicular to it. A washer, E, may also be soldered to the top so as

to aid in holding the tube. Procure a piece of steel rod, F, that will

fit in the tube D and turn freely. Sharpen one end of this rod and mount

a brass wind vane on the other end. A small metal cup, G, may be soldered

to a washer, H, and the whole mounted on the steel rod F in an inverted

position as shown, which will prevent water from getting down inside the

case along the rod. The cup G may be soldered directly to the rod. Make a

small arm, J, of brass, and fasten a piece of light spring, K, to one side

of it, near the outer end, then mount the arm on the steel rod so that it

is parallel to the vane and its outer end points in the same direction

as the arrow on the vane. The free end of the light spring on the arm J

should be broad enough to bridge the gap between adjacent turns of wire on

the resistance ring. Four bindings should then be mounted on the inside

of the case and all insulated from it with the exception of number 1.

Numbers 2 and 3 are connected to the ends of the winding and number 4 is

connected to number 3.

A second outfit should now be constructed, identical with the one just

described except that it should have a flat top with a circular scale

mounted on it, and the arm L should be controlled by a small handle in

the center of the scale. The position of the contact B may be indicated

on the scale by a slender pointer, attached to the handle controlling the

arm L.

Four leads of equal resistance should be used in connecting the two

devices and the connections made as shown. An ordinary buzzer placed in

the battery circuit will produce an interrupted current through the bridge

circuit and a balance will be obtained by adjusting the contact point B

until a minimum hum is heard in the telephone receiver.

Planting Seeds in Egg Shells

When growing flower plants from seeds, start them in halves of shells

from hard-boiled eggs. When the time comes to transplant them, they can be

easily removed by allowing the dirt in the shell to become hard and then

breaking off the shell, whereupon the plant is placed in the ground.

A pasteboard box provided with holes large enough to support the egg

shells can be used to hold them, unless egg crates are at hand. Two large

seeds such as nasturtiums and sweet peas can be planted in one shell, and

four seeds of the smaller varieties.--Contributed by Katharine D. Morse,

Syracuse, N. Y.

Locating Drip Pan under a Refrigerator

In replacing the drip pan of an ice box or refrigerator it is often

necessary to bend over in locating it under the drip pipe. This trouble

may be done away with by fastening two strips of wood in a V-shape to the

floor beneath the refrigerator. When the pan is shoved under, it will

strike one strip and slide along until it strikes the other. Then the

pan is sure to be under the drip pipe.--Contributed by Lloyd A. Phelan,

Beachmont, Mass.

Windmill for Light Power

The windmill shown in the sketch is one that will always face the wind,

and it never requires adjustment. It consists of a vertical shaft, A,

provided with a number of arms, B, on which are hinged square sails, C.

These sails are preferably made of wood frames covered with canvas. They

are provided with hinges, D, attached to the ends of the arms in such

a way that they offer resistance to the wind on one side of the wheel,

while they move edgewise against the wind on the other side, as shown. The

shaft of the mill can either be run in bearings set on an upright post,

the lower end of the shaft turning on a conical bearing, or collars may be

used on the bearings to keep it in position. The power can be transmitted

with gears or by a flat belt over a pulley.

[Illustration: Frames Hinged to the Arms]

A wheel of this kind is not adapted for high speed, but direct-connected

to a pump or other slow-working machinery will prove very

efficient.--Contributed by Edward Hanson, Kane, Pennsylvania.

A Small Bunsen Burner

[Illustration]

An excellent bunsen burner for small work can be made as follows: Draw

a glass tube to the shape shown, to produce a fine hollow point. Mark

carefully with a file and break at A and then at B. Bore or burn a hole

in a cork to fit the tube. Cut a V-shaped notch in the side of the cork

extending to the hole. Bend the lower tube at right angles and insert

it in a wood block, previously slotted with a saw to make a snug fit. A

little glue will hold the glass tubes, cork and base together. The air

mixture can be adjusted by sliding the upper tube before the glue sets.

The burner is especially adapted to continuous work, such as sealing

packages, etc. The flame will not discolor the wax.--Contributed by E. P.

Fert, Spokane, Wash.

The Hindoo Sand Trick

This is one of the many tricks for which the Hindoos are famous, and

was long kept a secret by them. It consists of placing ordinary sand

in a basin full of water, stirring the water and taking out the sand in

handfuls perfectly dry. It need scarcely be said that without previous

preparation, it is impossible to do so.

Take 2 lb. of fine silver sand, place it in a frying pan and heat well

over a clear fire. When the sand is thoroughly heated, place a small piece

of grease or wax--the composition of a paraffin candle preferred--in the

sand, stirring it well to get it thoroughly mixed, then allow the sand to

cool. When this sand is placed in a basin of water, it will be apparently

dry when taken out. It is very important that only a small portion of the

adherent be used so that it cannot be detected when the sand is examined

by the audience. The explanation is that the grease or wax coating on each

sand particle repels the water.--Contributed by Mighty Oaks, Oshkosh, Wis.

A Kite-Line Cutaway for Toy Parachutes

The cutaway is made of a small piece of board, a cigar-box lid, an old

yardstick or a piece of lath, which should be about 6 in. long. Common

carpet wire staples are used to hold it on the string. The under side has

a wire bent into such a shape as to form a loop at the forward end over

the kite string, then running back through the two staples at the one side

and through two staples at the other side.

[Illustration: Wires Attached to the Traveler]

The parachute should have a small wire ring fastened at the weight end

so as to fasten in the carrier, and should be put between the two staples

that are closest together on the under side of the carrier. A small nail

or button--anything larger than the loop in the wire--should be attached

to the kite string a few feet from the kite. When the parachute is

carried up the kite string, the knob on the string will strike the loop

of the wire on the carrier, which releases the parachute and allows it to

drop. The carrier will return of its own weight to the lower end of the

string.--Contributed by I. O. Lansing, Lincoln, Neb.

A Cherry Pitter

Procure an ordinary quill feather and cut the tip off to form a small

hole. Do not remove so much of the end that the cherry stone can stick

in it. The hole must be slightly smaller than the cherry stone. Push

the quill through the center of the cherry and the stone will come out

easily.--Contributed by Harold Wynning, Chicago, Ill.

To Hold a Fish while Removing the Scales

Insert a screwdriver or ice pick in a fish as shown, and the scales can be

removed much better and quicker than in any other way. The handle of the

screwdriver affords an efficient grip so that the fish can be held firmly

on the board and every scale can be removed.

[Illustration: Holding Fish for Scaling]

Carrying Stone Jars

The handholds on stone jars are usually not large enough to carry the

jars safely when they are full. If the handles of an old galvanized tub

are riveted to a leather strap long enough to reach under the bottom and

almost to the top on each side, the jar can be handled without danger of

being dropped. The fingers are placed in the handles to carry the weight,

while the thumbs are used to keep the jar from tipping. By placing a

buckle near one end, the strap may be used for carrying a jar of any

size.--Contributed by C. H. Floyd, Elwood, Ind.

Vibrator for a Spark Coil

If you do not have the time to make a vibrator or electrolytic interrupter

for a spark coil, a common electric door-bell makes a good substitute.

Connect one of the primary wires to the binding-post of the bell that is

not insulated from the frame, and the other primary wire to the adjusting

screw on the make-and-break contact of the bell, as shown in the sketch.

The connections are made from the batteries to the bell in the usual

manner.--Contributed by Ralph Tarshis, Brooklyn, N. Y.

[Illustration: Bell Used as Vibrator]

Head Rest for a Chair

While seated in a chair a person very often desires to lay the head back

in resting. A support for the head is lacking in the low-back rockers and

ordinary chairs. A detachable, padded support can be easily made at home

for placing on any low-back chair and used as a head rest.

[Illustration: Rest on Chair Back]

The support standards can be made of wood or metal as desired. If metal

is used, the rest will have some springiness, which combined with the

pad will insure much greater comfort than the hard rigid back. A cloth

or paper is placed over the back of the chair to prevent marring of the

varnish or wood.

Lighting a Lawn Mower for Use at Night

Those who desire to do so, or must, for lack of time during the day, may

use their lawn mower at night and light the front of their machine with

an ordinary bicycle lamp. The arm to hold the lamp can be attached with

screws to the handle as shown in the sketch. It is easily made from a

piece of hoop or bar iron.--Contributed by Samuel F. Reid, Minneapolis,

Minn.

Tying a Rosette in a Couch-Cover Corner

In the accompanying illustration is shown a very simple method of tying

a rosette in the corner of a couch cover. The use of the average couch

cover as a throw-over leaves a large corner which drags upon the floor. To

dispose of this extra length and at the same time make an artistic corner,

the Upholsterer suggests the following method:

[Illustration: Different Stages in Tying the Rosette (Fig. 1, Fig. 2)]

Spread the couch cover on the couch so that the surplus is evenly divided

between the sides and ends, and pass a pin through the cover to show each

corner as in Fig. 1. Measure the distance from each corner of the couch

to the floor, Fig. 2, and measuring from the point of the corner, mark

the same distance by the insertion of another pin, repeating in all four

corners. The distance between the two pins at each corner now defines the

amount of surplus that is to be taken up. Chalk a circle to include the

portion between these two pins, as shown in Fig. 3, and with a circular

needle and stout stitching twine run a shirring thread around the circle,

and when this is drawn tightly and tied, the surplus is formed into a

rosette, while the corner may be draped into an artistic cascade, as shown

in Fig. 4.

[Illustration: (Fig. 3, Fig. 4)]

Driving Screws

[Illustration]

A wood screw having the threads hammered flat on two sides can be easily

driven in with the flattened sides parallel to the grain of the wood. When

the screw is turned a quarter turn the remaining threads cross the grain

and hold as well as if they had been turned in all the way. This is an

especial advantage where something is wanted which is easily inserted and

will hold better than a nail.--Contributed by P. D. Merrill, Chicago.

A Power Windmill

The windmill shown is somewhat different from the ordinary kind. It is

not a toy, nor does it approach in size the ordinary farm windmill, but

is a compromise between the two, and in a good strong wind, will supply

power enough to run a washing machine, a small dynamo, an emery wheel, or

any other device used in the home workshop. The wheel is about 5 ft. in

diameter, with eight blades. The over-all length is about 6 feet.

The windmill is easily made and the cost is within the means of the

average boy. There is not a part used in its construction that cannot be

found about an ordinary manual-training shop. The most difficult parts

of the construction will be described in detail. Symmetry and smoothness

of design should be preserved and the parts made as light as possible

consistent with strength and durability.

[Illustration: The Hub Consists of Two Parts, Each Having Four Arms for

Holding the Blades (Fig. 1)]

The Wheel

As shown in the drawings, the wheel has eight blades. Ordinarily the

use of eight blades makes it difficult to construct a hub of sufficient

strength to carry them. Where so many blades radiate from a common center

it is almost impossible to provide an anchorage for each blade. To provide

a maximum of strength coupled with simplicity of design, the plan of using

two hubs of four arms each was adopted in the construction of this mill.

The ordinary hub of four arms is simple to make and quite strong. Four

pieces of straight-grained oak, each 16 in. long and 1-7/8 in. square, are

used in constructing the hubs. The manner of notching each pair of pieces

together is shown in Fig. 1. The slope for the blades is made to run in

opposite directions on the ends of each crosspiece. The slope is formed

by cutting out a triangular piece, as shown.

[Illustration: (Fig. 2)]

The two hubs, thus formed, are mounted on the shaft, one behind the other,

in such positions that the arms will be evenly divided for space in the

wheel circle. These details are shown in Fig. 2. The blades, Fig. 3, are

made of thin basswood or hard maple, and each is fastened in its place by

means of two 3/8-in. bolts, in addition to which a few brads are driven

in to prevent the thin blades from warping.

[Illustration: (Fig. 3)]

The Gears

This windmill was designed to transmit power by means of shafts and gear

wheels, rather than with cranks and reciprocating pump rods, such as

are used on ordinary farm mills. To obtain this result, an old sewing

machine head was used. Such a part can be obtained from a junk dealer or

a sewing-machine agent. The head is stripped of its base plate with the

shuttle gearing; likewise the needle rod, presser foot, etc., are taken

from the front end of the head along with the faceplate. The horizontal

shaft and gear wheel are taken out and the bearings reamed out for a

1/2-in. shaft, which is substituted. The shaft should be 2 ft. in length,

and 8 or 10 in. of its outer end threaded for the clamping nuts which hold

the two hubs in place, as shown at A and B, Fig. 2. The gear wheel is also

bored out and remounted on the new shaft.

[Illustration: The Supporting Standard Holds the Machine Head with the

Wheel and the Vane on an Axis (Fig. 4)]

The supporting standard is constructed of oak, with mortise-and-tenon

joints, as shown in Fig. 4. The width of the pieces will depend on the

kind of sewing-machine head used. It may be necessary also to slightly

change the dimensions. The machine head is fastened on the support with

bolts. A sleeve and thrust spring are mounted on the shaft, as shown. The

sleeve is made of brass tubing, of a size to fit snugly on the shaft.

A cotter will keep it in place. The sleeve serves as a collar for the

thrust spring, which is placed between the sleeve and the standard. This

arrangement acts as a buffer to take up the end thrust on the shaft caused

by the varying pressure of the wind on the wheel.

[Illustration: (Fig. 5)]

The Vane

To keep the wheel facing the wind at all times, a vane must be provided.

It is made of basswood or hard maple, as shown in Fig. 5. It is not built

up solid, air spaces being left between the slats to reduce the wind

resistance. Unless built in this manner, the vane is liable to twist off

in a gale. The horizontal slats are 1/4 in. thick, and the upright and

cross braces 3/8 in. thick, while the long arm connecting the vane to the

supporting standard is 1/2 in. thick.

The supporting standard, carrying the wheel and the vane, must revolve

about a vertical axis with the changes in the wind, and this vertical

axis is supplied in the form of a piece of gas pipe which runs through

the supporting standard at the points marked C and D, Fig. 4. Ordinary

pipe fittings, called flanges, are bolted to the frame at these points.

The coupling in the gas pipe beneath the supporting standard serves as a

stationary collar to support the weight of the whole mill. The vane should

be placed correctly to balance the weight of the wheel.

The shaft passes through the framework of the mill on the inside of

the pipe, as shown at E. A 3/8-in. soft-steel or wrought-iron rod is

satisfactory for the shaft, as no weight is supported by it and only a

twisting force is transmitted. The use of a larger rod makes the mill

cumbersome and unwieldy. The upper end of the shaft is fastened to the

shaft that projects from the under side of the machine head by means of

a sleeve made of a piece of 3/8-in. pipe. Two cotters hold the shafts and

sleeve together.

[Illustration: The Lower End of the Shaft has a Horizontal Shaft Geared

to It for the Drive Pulleys (Fig. 6)]

At the lower end of the shaft, inside the workshop, the device shown

in Fig. 6 is installed. The purpose of this appliance is to provide a

horizontal shaft upon which pulleys or driving gears may be mounted.

The device is constructed of another sewing-machine head similar to the

one already described. The head is cut in two and the separate parts

mounted on suitable supports. The gap between the sawed portions permits a

pulley to be fastened on the shaft to serve as the main drive. The wheel

propelled by the treadle of the sewing machine will make a good drive

wheel. The small handwheel, originally mounted on the machine-head shaft,

is left intact. This arrangement gives two sizes of drive wheels. Heavy

sewing-machine belts will serve to transmit the power.

The Tower

The tower can be built up in any manner to suit the conditions. Ordinarily

sticks, 2 in. square, are suitable. These are well braced with wire and

fastened securely to the roof of the shop. The arrangement of the tower

with the mill is shown in Fig. 7.

[Illustration: the Manner of Building the Tower on Which the Supporting

Standard Revolves (Fig. 7)]

Telegraph Code on Typewriter Keys

A very simple and practical method of transcribing wireless time and

other messages on the typewriter without having such perfect knowledge

of the Morse system as to be able to immediately translate it into the

common alphabet is the following: The characters of the Morse system

are inscribed on small slips of paper--thus, three dots (...), for the

letter S; two dashes (--), for the letter M, etc.--and these slips are

pasted on the corresponding keys of the typewriter. The operator puts on

his receiver, and the proper key is struck as he hears the corresponding

Morse letter. As there are no capitals, spacing between words, or even

punctuation, the manipulation of the typewriter is much simplified, and

it is easily learned to record the signals as fast as they are heard.

An Aid in Sketching Profiles

The means usually employed by most beginners to obtain the correct outline

of an object, such as tracing or a pantograph, make them dependent on

mechanical help rather than train the eye to form and proportion a drawing

correctly. The device shown not only greatly assists the beginner, but

actually trains him toward a point where he can dispense with any such

device and correctly sketch by free hand. It also has the effect of

encouraging the beginner, because his first efforts will not be complete

failures, as is usually the case.

[Illustration: The Fine Wire is Bent as Near as Possible to the Outline

of the Object]

The device consists of a rather fine wire bent in the shape of a human

profile and supported on a stand or base. The stand may be dispensed with,

however, and the wire held in the hand. In use, it is placed near the

model or person whose profile is to be drawn; then, after closing one eye,

it is set at a position where it will correspond to the features of the

model. This enables one to note the variations between the wire and the

model's features. For instance, the forehead may recede from the wire at

the top, or the nose may have a different slant or shape.

The paper on which the drawing is to be made should have a faint outline

drawn by laying the wire upon it and marking around it with a soft pencil.

Having noted the variations between the wire and the features, proceed

to draw the profile, observing the same variations, and when the sketch

is completed, erase the faint outlines. Then compare the drawing with the

model without using the wire, and make final corrections. The dotted line

indicates the outline to be erased.

The drawing may be made larger or smaller than the bent wire, but the

outline on the paper must be kept in exactly the same proportion. It

is not necessary that the wire be bent so that it represents perfect

features. With the use of this device one forms a habit of comparing

and proportioning, which applies to the correct sketching of all

objects.--Contributed by Will L. Burner, Columbus, Ohio.

A Small Hydroelectric-Power Plant

Wherever a water pressure of over 30 lb. is available a small

hydroelectric-power plant will produce sufficient electric current for

any light work, such as charging storage batteries, operating sewing and

washing machines, toys, etc. The design is for a 6-in. hydraulic motor

of the Pelton type, which will operate well on almost all city-water

pressures, and at 80 lb. will drive a 100-watt generator to its full

output.

The castings may be procured from any foundry cheaply, so that these parts

need not trouble the builder. The patterns can be constructed easily and

are not so complicated that they will tear the molds when being removed.

They are made from well seasoned white pine, 1/4 in. thick. Fill in all

sharp corners with small fillets. All the patterns should taper slightly

from the parting line.

[Illustration: Layout for the Casing, Cover and Wheel for the Construction

of a Hydraulic Motor That will Drive a Small Dynamo, to Produce Current

for Experimental Purposes, to Charge Storage Cells or to Run Electric Toys

(Fig. 1)]

The motor casing is shown in Fig. 1. It is made with a wide flange so

that the cover plate can be bolted to it. The lug A is to give additional

strength and thickness to the side so that it may be drilled and tapped

for the nozzle. The legs B and C are for bolting the case to a base or

support. The outlet pipe is of lead, 1-3/4 in. outside diameter, and the

hole for it in the case can be either drilled or cored. Solder the pipe

flush with the inside of the casing. Drill and tap the holes around the

flange for 8,32 bolts. The shaft hole must be drilled very carefully.

Drill 1/4-in. holes in the feet. The oil holes are 1/8 in. in diameter.

File the surface of the flange smooth and also the inside shoulder of the

bearing lug. Drill and tap the nozzle hole for a 3/4-in. pipe thread.

[Illustration: (Fig. 2)]

The cover plate is shown in Fig. 2, This is bolted to the casing with

8,32 brass bolts, 1/2 in. long. The holes for them are drilled 3/16 in. in

diameter. A shallow hole, for the end of the shaft to fit in, is drilled

in the lug, as shown. It does not pass all the way through the plate. File

the inside face of the lug smooth and also the edge of the plate where it

joins the casing.

[Illustration: (Fig. 3)]

The wheel, with brackets attached, is shown in Fig. 3. This style of wheel

need not be followed out closely. Bore the hub centrally for a 1/4-in.

shaft and fit in two setscrews. Drill and tap the rim for the buckets with

a 1/4-in. standard tap. The buckets must be evenly spaced and bolted on

to make the wheel balance.

[Illustration: The Best Shape of the Buckets to Take Up the Force of the

Water (Fig. 4)]

The buckets are shown in Fig. 4. They may be cast from iron or babbitt.

The sharp ridge in the center provides for a deviation of the water jet

as it flows on the bucket. The ridge divides the bucket into two equal

lobes which turn each division of the jet through almost 180 deg., using

all the kinetic energy in the jet. This is shown at D. The dividing ridge

must lie in the plane of the revolution, so that each bucket will enter

the center of the jet. The buckets being evenly spaced on the periphery

of the wheel, only one at a time receives the force of the jet, the one

in front and the one behind clearing the jet.

[Illustration: (Fig. 5)]

The nozzle is shown in Fig. 5. It can be made of iron or brass. The inside

gradually tapers from 3/4 to 3/16 in. It has a 3/4-in. pipe thread and is

screwed into the hole in the case from the inside and is secured with a

lock nut. Enough additional threaded portion is left protruding to allow

the supply pipe to be connected.

When assembling the motor, fasten the wheel to the shaft with the two

setscrews, and place a metal washer, E, on each side of the wheel. Place

the wheel in the casing and screw the cover plate in place. A thin rubber

gasket should be placed between the cover and the casing to provide a

water-tight joint.

[Illustration: The Motor as It is Coupled to Drive the Dynamo, and the

Water Connections (Fig. 6)]

The general arrangement of the plant is shown in Fig. 6. The motor and

dynamo are mounted on a heavy wood base, which in turn is firmly bolted

to a concrete foundation. Level up the two machines by the use of thin

washers on the bolts between the base and machine. A heavy sleeve and

setscrews are used to connect the two shafts. The connection to the water

supply is made with 3/4-in. pipe, with a globe valve in it to regulate

the flow of water. Any dynamo of about 100-watt output can be used.

Paper Shades for Electric-Light Globes

The appearance of an electric-light globe can be very prettily improved

by making a shade of crêpe paper of any desired color for each one.

Canary-colored crêpe produces a soft, mellow effect. Pale blue, yellow,

red and, in fact, all the colors can be used, making a very pleasing

variety.

[Illustration: Two Pieces of Crêpe Paper Stitched Together and Ruffled,

to Make a Fancy Electric-Light Shade]

The body of the shade is made of a piece of paper about 5-1/2 in. wide

and 3-1/2 ft. long. The width will vary with the length of the globe to

be covered, and it is best to have it full, as the edge can be trimmed

even with the lower end of the globe afterward. Another piece of the same

color is cut 2-1/2 in. wide and of the same length. This piece makes the

ruffle.

The smaller piece is placed on the larger centrally, and both are stitched

together with a running stitch, using a needle and cotton thread. A plain

running stitch is also made 1/4 in. from one edge of the larger strip. The

material is gathered along both threads. This operation makes the material

shrink in length. Wrap it around the globe, pulling the threads taut so

that the ends of the paper will just meet. Tie the threads and clip off

the extending ends. If the paper extends beyond the end of the globe,

trim it off with the shears. Ruffle the two edges of the narrow strip and

the lower edge of the larger one. This operation is simply stretching the

edge of the crêpe to cause it to stand out.--Contributed by Jas. A. Hart,

Philadelphia, Pa.

Renewing the Markings on Graduates

Graduates that have been in use a long time, especially for measuring

alkalies, become unreadable. The graduations are easily restored in

the following manner: Moisten a small piece of absorbent cotton with a

solution of white shellac, cut in alcohol. Rub this well into all the

etched parts and allow to dry for about two minutes, then rub in a fine

whiting or litharge with an old toothbrush. If red is desired, use rouge;

if black is preferred, use lampblack or powdered graphite. When dry, wipe

off the excess pigment with a cloth moistened in alcohol.--Contributed by

A. C. Norris, Rockford, Ill.

Repairing a Broken Ball-Clasp Purse

[Illustration]

Having occasion to repair a purse of the ordinary ball-clasp kind where

one of the stems was broken off and lost, I first had some trouble in

finding a way to repair it. I started to take off the remaining stem in

an attempt to replace the locking device with another kind, and in bending

it down toward the opposite side, I happened to close the purse and found

that it locked just as well as if there had been two balls on it. I have

since repaired two other purses in the same manner and found that they

worked well.

The idea is to bend the remaining clasp over until it is low enough to

come in contact with and to spring over the other side, thus giving the

same snap and holding qualities as before.--Contributed by W. C. Loy,

Rochester, Ind.

Automatic Valve for a Funnel

[Illustration]

Where liquid is run through a funnel into an opaque bottle or earthen jug,

the filling cannot be watched, and if not watched constantly, the vessel

will overflow. This can be obviated by applying the automatic valve to the

funnel stem, as shown. A washer support is soldered or otherwise fastened

in the upper end of the stem, or at the base of the sloping part, and a

crossbar is fastened to its upper surface across the hole. The crossbar

is centrally drilled to receive a small rod or wire, to which is attached

a valve that will cover the hole in the washer. A cork is stuck on the

lower end of the rod. The location of the cork on the rod should be at

a point a little below the level to which the bottle or vessel is to be

filled.--Contributed by H. W. Hilton, Hopington, B. C.

Chisel Holder for Whetting

To obtain the proper slope and apply a fine cutting edge, the plane

iron or chisel must be held at the proper slope while grinding, and

especially so when whetting. The illustration shows a holder to keep the

iron or chisel at the proper slope. It consists of a block of wood with

a sloping cut at the right angle to make two pieces. One of these pieces

is permanently fastened to the strip at the back, while the other is

held with a bolt passing through a notch in the strip for adjusting or

clamping. The rear end of the back piece is fitted with a large screw hook

or L-hook to provide a slide to keep the rear end of the holder at the

right height. The iron or chisel is inserted between the sloping edges of

the blocks and clamped in place, then the L-screw is adjusted for height

to secure the proper angle on the stone. It is then only necessary to move

the block and tool back and forth over the stone.

[Illustration: The Tool Edge is Kept at the Proper Angle While It is Run

over the Stone]

A Large Hole in a Small Piece of Paper

It would seem impossible to cut a hole in a piece of paper, 2 in. wide

and 3 in. long, large enough to allow a person's body to pass through it,

but if carefully cut as shown by the lines in the sketch, one will find

with surprise that the paper can be extended so that the feat is easily

accomplished. Make the cuts about 1/8 in. apart and these will allow the

paper to expand several times its size.--Contributed by H. Martine Warner,

E. Orange, N. J.

Homemade Bunsen Burner

The amateur craftsman, at some time or other, needs a hot flame for

certain kinds of work, and a Bunsen or alcohol flame is brought into

service. The gasoline and alcohol flames have their drawbacks, one of

which is the starting of the burner and the waiting for the heat. They are

also unhandy in directing the flame on parts of the work. As I desired a

burner for quick work and one whose flame I could direct at any angle,

for repoussé and chasing on copper and silversmith's work, I made the

one shown in the sketch to attach to a hose and connected it with the

gas pipe of the illuminating system in the house. It consists of a hose

connection into which a piece of pipe, 5 in. long, is fitted. The hose

connection is also fitted with a small nozzle, A, for the gas, and the

pipe has an opening through it at the end of the nozzle.--Contributed by

John Koestner, Brooklyn, N. Y.

Cane-Seat Cleaner

A rapid and practical method of removing stains and discolorations from

the cane seats of chairs, wickerwork, etc., is to use oxalic acid and

powdered pumice.

Dissolve oxalic-acid crystals in hot water and saturate a small stiff

brush in it, then dip the brush in the powdered pumice and rub the

discolored cane briskly with the brush.--Contributed by W. F. Jaquythe,

Shade-Roller and Curtain-Pole Bracket

The main advantage of this shade bracket is that a person can lower it

for adjusting the shade or in changing curtains while standing on the

floor, thus eliminating the use of a step ladder and the danger possibly

attending such use.

[Illustration: The Brackets as They are Attached to a Window Casing for

Lowering the Curtain Pole (Fig. 1, Fig. 2)]

The front elevation of a window with bracket attachment in position

is shown in Fig. 1, and a cross section in Fig. 2. The position of the

curtain pole when the brackets are lowered is shown by the dotted lines.

A detail sketch of the support end is given in Fig. 3 and one bracket is

shown in Fig. 4.

[Illustration: The Attachments, Supports and Brackets for Holding both

Curtain Pole and Shade Roller (Fig. 3, Fig. 4)]

The curtain pole A is fastened to the brackets B with 1/4-in. dowel pins,

C. These pins and the pole keep the brackets from spreading at the top,

so that a shade roller, D, may have its attachments fastened to the inner

sides of the brackets. A small pulley, E, is attached to the window casing

above the right bracket and a double pulley is located above the left,

cords being passed through them, down along the casing to a point within

easy reach, and fastened in any manner desired.

All that is necessary to change the curtains or fix a shade is to loosen

the cord and allow the brackets to drop down until they may be easily

reached.--Contributed by James F. Napier, Montreal, Can.

Planing Arrow Sticks

While making some bows one day I discovered I had no suitable dowel

sticks for the arrows, so I started to make them out of 1/4-in. square

stock. I found it rather difficult to plane these pieces until I hit

upon the scheme shown in the sketch. I procured a piece of ordinary

tongue-and-groove flooring and clamped it in the bench vise, then drove

a nail in the groove to act as a stop, and in no time I had the sticks

planed into arrows.--Contributed by J. F. Culverwell, Washington, District

To Clean Shellac from a Brush

Put the brush in a strong, warm solution of borax and water, and then wash

in clean, warm water. If the bristles have become hard, allow the brush

to remain in the solution until soft, keeping the solution warm in the

meantime; then wash it out in warm water.--Contributed by N. J. Shattuck,

Woburn, Mass.

Lathe Dogs

In the absence of a full equipment of lathe dogs the amateur can make them

cheaply from pieces of iron pipe. One of these is shown in the sketch. A

section of pipe, 1-1/2 in. to 3 in. long, is partly cut away, as shown,

leaving a projection of metal 1 in. wide. One or more setscrews are fitted

in the round part, and the dog is complete.

[Illustration: Two Forms of Lathe Dogs That are Quickly and Cheaply

Constructed]

A dog, or driver, may also be made of two U-clamps and two bolts as shown.

This is especially useful for large work, where the cost of a dog would be

prohibitive. After these two clamps are bolted on the work to be turned

a bolt is attached in the faceplate that bears against the clamp, thus

turning the work.

To Remove a Splinter from the Flesh

Quite frequently small particles of steel, splinters, or thorns are

run into the flesh and cannot be removed with the fingers. These can be

readily removed in the following manner: Press the eye of an ordinary

needle over the protruding end, then turn the needle until the edges bind

or clinch. While in this position, raise the needle and out comes the

splinter.

Holders for Displaying Magazines

[Illustration]

Papers and magazines often are sold in drug stores where the display

space usually is limited, especially in the window. The method used by one

druggist gave space for the magazines in the window without interfering

with the other goods.

The back of the window was arranged with rows of hooks, three hooks

for each magazine, two at the top edges and one in the center at the

bottom. The magazine is easily slipped into these holders, and the whole

presents a tidy appearance. The hooks are the ordinary screwhooks that

can be obtained from a hardware or furniture store.--Contributed by T. F.

Waste-Paper Basket

[Illustration]

The covering of a broken demijohn was used in the manner shown as a

waste-paper basket. The glass was broken out and the covering soaked in

water, after which the splints were turned down and tied with a cord. This

I found to make a first-class waste-paper basket.--Contributed by A. S.

Lettering Photographs

Amateur photographers often write, or print, the names of the subjects on

the mounts, or in the albums, with white ink or scratch it on the negative

so that it will print in the picture.

A very good method is to take ordinary black ink and do the lettering on

the sensitive paper before it is printed under the negative, being careful

not to scratch the paper. After printing the paper to the proper shade the

toning and fixing baths will wash away the ink and leave the lettering in

white.

The lettering is easily accomplished and a post card can be sent with

any message desired on any negative, the inscription being printed on the

paper so that the negative is unharmed for other printing.--Contributed

A Stamp Moistener

[Illustration]

A handy stamp moistener and envelope sealer can be made by procuring a

small medicine bottle or glass vial and inserting a piece of felt or other

wicking material in the place of the stopper, and filling it with water.

This moistener will be found handy for a small office where the mail

is quite heavy, but not big enough to warrant the purchasing of a

sealing machine. This moistener is sanitary and replaces the wet

sponge.--Contributed by Theo. J. Becker, Kansas City, Mo.

A Window Lock

Varnished Candles Burn Longer

The heated tallow or wax of a candle runs down the sides and this results

in a considerable waste. This waste can be stopped by coating the new

candles with white varnish and laying them aside for a few days to harden.

The varnish will keep the melted tallow or wax from running away and it

is used in the wick.

Guides for a Mill File

Having a large number of wires to file true on the end I devised a way

to do this with the use of some old worn-out and discarded files that had

good cutting edges. A piece of sheet copper, about the same length as the

files, was bent to fit over one edge and both sides of the file, allowing

both edges to project about 1/4 in. This made a guide that prevented the

edge of the file from slipping off the end of the wire. The guide was

held in place on the file by cutting a slit in the projecting edges, about

1/4 in. from the end, and turning these separated parts back on the file.

[Illustration: Guide for Using the Edge of Worn-Out Files on Small Round

or Square Stock]

A Simple Motion-Picture Machine

The drum A is a piece of wood, 1-3/4 in. long and 1-3/16 in. in diameter,

supported on the end of a round stick, B, which can be made in one piece

with the drum, if a wood lathe is at hand, but a piece cut from a curtain

pole and a lead pencil inserted in a hole bored in the end will answer

the purpose. Be sure to have the diameter of the drum 1-3/16 inches.

[Illustration: The Parts for Making the Revolving Drum for Holding the

Strip of Pictures]

Provide a base piece, C, 1/2 in. thick and 2 in. square, and fasten a

piece of cardboard having a slit E, as shown. The cardboard should be

2 in. wide and 2-1/2 in. high, the slit being cut 1/2 in. in width,

1/4 in. from the top and 3/4 in. from the bottom. A hole is bored in the

center of the block to admit the standard B easily.

The next step is to provide the picture and attach it to the drum. A

picture of a boy pounding cobblestones is shown in the sketch, at F,

which should be made on a strip of paper 4-3/8 in. long. This is glued

or attached with rubber bands to the drum. The drawing can be enlarged in

pen and ink, or can be reproduced as it is, if a hand camera is at hand,

and a print used on the drum.

[Illustration: The Different Positions of the Picture will Appear in

It is only necessary to put the parts together, grasp the base in one hand

and turn the support B with the other, when, looking through the slot E,

the boy is seen pounding the stones. Various pictures can be made and the

strips changed.--Contributed by C. C. Fraser, Saginaw, Mich.

Substitute for Cleats on Boards

The necessity for using more than one cleat for fastening two boards

together may be done away with by using the device shown in the sketch.

The center cleat prevents the boards from buckling while the sides are

tightly held by these simple flat fasteners. The fasteners are made of tin

cut as indicated, slipped between the edges of the boards and the parts

bent over and tacked. Where the strain is not too great the holders may

be used without a cleat, making an effective flat fastening.--Contributed

Attaching Door Knobs to Locks

When putting a lock on a door it is often difficult to press the two knobs

together tightly enough to prevent them from rattling and still be able to

insert the screw into the shank. By using a piece of board, 1 in. thick,

6 in. wide and 1 ft. or more in length, with a V-shaped piece cut out of

one side, the knobs can be easily forced and held together while the screw

is inserted.--Contributed by H. Musgrave, Sidney, British Columbia.

A Finger-Nail Buffer

The flywheel on a sewing machine is usually turned with a semicircular

face and this makes a good base on which to apply a piece of chamois skin

for use in buffing nails. A strip of the chamois is cut the length of the

wheel's circumference and small holes pierced in its edges, through which

strings are run to hold it to the rim of the wheel. The chamois can then

be removed or left on the wheel as desired. Run the machine and hold the

nail on the buffer. When there is a free wheel on the machine this makes

an excellent buffing device.

Reducing Amperage of a Fuse Wire

It is sometimes necessary to use an electrical fuse of smaller amperage

than those at hand, and for experimental work this is often the case. A

gas pipe, 9 in. long, threaded at both ends, one end being fitted with

a screw cap and the other with a pipe flange. This part is shown in Fig.

1. A piece of sheet metal is cut in the shape shown in Fig. 2 and bent to

form a cone, so that the smaller end will fit snugly around the pipe and

the base be 9 in. in diameter. The joined edges are riveted together. The

assembled parts will appear as shown in Fig. 3.

The metal used for plating consists of bismuth, 4 oz.; antimony, 4 oz.,

and pure block tin, 10 lb. Place the antimony in the crucible and melt

it, then add the tin and bismuth. A flame from an ordinary gasoline burner

will be sufficient to heat the crucible.

Clean the article to be coated by rinsing it in strong caustic potash,

which will remove all grime and grease, then dip it in a strong solution

of sal ammoniac and water. Dry it and then dip it in the melted metal,

allowing it to remain there about 1 minute, then remove and plunge it in

a bath made of 1 lb. of sal ammoniac and 1 gal. of water. The article is

then dried in sawdust.

and a Piece of Sheet Metal (Fig. 1, Fig. 2, Fig. 3)]

The coating put on in this manner is a nice, shiny plate that will stand

a lot of wear. No polishing or grinding is necessary.--Contributed by A.

A Model Steam-Turbine Boat

A piece of thin board, or shingle, is cut to the shape of a boat and two

standards are fastened to it. The standards have notches cut in them to

hold an ordinary baking-powder can which is used for the boiler. The lid

of the can is soldered on, and a small hole punched in one side with an

awl. Two candles are used to heat the water.

[Illustration: Model Turbine Boat Using a Baking-Powder Can for a Boiler

with Candles as Fuel]

The turbine is constructed on an axle made of a hatpin which runs

through the top of the standards for bearings. The paddles are made of

cardboard, or better still, pieces of thin sheet tin, cut and bent as

shown at A, and three of these are attached to a three-cornered block

of wood fastened to the shaft, as shown at B. The manner of attaching

the shaft for the propeller is shown at C. The propeller consists of a

piece of tin, slightly twisted and attached to the shaft with solder.

The pulleys are located as shown and connected with a string band. The

hole made in the can should be pointed to one side of the turbine shaft

so that the escaping steam will strike one side of the paddles on the

turbine.--Contributed by McKinley Wood, Ava, N. Y.

Plant Shelf for a Window

An ingenious and simple method of putting up window shelves for winter

plants so that the window casing and facing are not marred is shown in the

sketch. The materials required are one shelf, about 8 in. wide, 1-1/2 yd.

of picture wire, two screweyes, two fence staples, and two strips of wood,

to raise the shelf slightly from the window sill. The board for the shelf

is cut to fit the window frame and casing. The picture wire, screweyes and

staples are attached as shown. When cleaning the window the shelf can be

drawn out of the way.--Contributed by H. C. Dixon, Johnstown, Pa.

[Illustration: The Shelf is Hung on Wires Attached to Screweyes Placed in

the Facing Edge]

A Camera Support

A device which, in many instances, will take the place of a tripod, can

be made of a brass wood screw and can be carried in the pocket as easily

as a pencil. The screw should be 3 or 4 in. long and 1/4 in. in diameter.

Cut off the head and thread the end about 1/2 in. to fit the socket in

the camera. Drill a 1/8-in. hole through the metal just below the threaded

part and insert a short piece of 1/8-in. wire. Slip a washer over the end,

down to the wire, and fasten it with solder.

[Illustration: Substitute for a Camera Tripod That can be Carried in the

Pocket Like a Pencil]

The device can be turned into a tree, post or a stick thrust into

the ground, and the camera screwed onto it and adjusted to any

angle.--Contributed by O. D. Turner, Seattle, Wash.

Combination Tool for Amateur Draftsmen

A common 6-in. mill file can be converted into a very useful tool for an

amateur draftsman. Grind the end of the file as shown in the sketch and

use it for prying out thumbtacks that are driven in too tightly. Grind

the base of the tang into a knife blade for sharpening pencils, shaving

chalk, opening envelopes, etc. Shape, by careful grinding, the part A for

cutting and trimming sheets. Grind one edge of the file round and polish

it for smoothing and burnishing purposes. Grind a sharp point on the tang

for perforating sheets. A piece of rubber stuck on the tang end answers

the double purpose of a protector and eraser. The file part is used for

finishing points on pencils.

Varnishing Bases for Electric Apparatus

It is quite difficult to keep from making finger marks on freshly

varnished boards used as bases on electric devices. It is easily avoided,

however, by procuring a large spool and fastening it to the bottom of

the base with a wood screw. The spool will serve as a handle while the

varnish is applied, and also makes a stand for the board while the varnish

dries.--Contributed by Jacob Laudan, Louisville, Ky.

Waterproof Shoe Dressing

Melt some tallow and, while it is hot, put in some scraps of rubber from

old rubber shoes or boots. Be careful to select rubber that is free from

cloth. Put in as much of the rubber as the tallow will absorb. Stir freely

while it is melting, and keep it away from any flames. Allow it to cool

and set away for future use. Take enough for immediate use and warm it

sufficiently so that it may be applied with a brush.--Contributed by F.

S. Cummings, Detroit, Mich.

An Adjustable Bench Stop

A simple adjustable bench stop for light work may be made from a piece

of 1-in. broom handle and a piece of piano wire. Plane a flat surface on

the broom stick and drill two 1/16-in. holes, about 1/4 in. deep, 1/4 in.

from each end. Bend the ends of the wire to enter the holes and have the

wire of such length as to give it a slight curve between the ends when it

is in place on the stick.

[Illustration: The Spring Wire will Hold the Stop at Any Desired Position

for Height]

Bore a 1-in. hole through the bench top where it is desired to use the

stop and cut several grooves, as shown, in the walls of the hole with a

compass saw. The spring wire will slide into a groove and hold the stick

wherever it is set. The position of the face can be changed by inserting

the stick so that the wire will enter the right groove.--Contributed by

Alan H. Andrews, Fall River, Mass.

A Crochet Hook

In making some kinds of lace work different-sized hooks must be used

as the work proceeds. Considerable time will be lost in changing from

one hook to another, if they are separate. The best way is to mount all

the hooks necessary on one handle, as shown in the sketch. The handle

part is made of a large wire or small rod, bent to the shape shown and

with holes drilled through the ends for a small rivet. The ends of the

hooks are drilled or bent to fit on the rivet. A small tin ferrule is

made to slip over the handle and the hooks not in use. All hooks but the

one in use are turned back into the handle and the ferrule slipped into

place.--Contributed by Miss Nita S. Ingle, W. Toledo, O.

Writing Board for Children

A writing desk for a child can be easily made as shown in the sketch.

The materials necessary are a board of suitable size, two screwhooks,

four screweyes and a pair of rods for braces. The hooks are screwed into

the back of a chair and the screweyes into the board, as shown. This

desk is instantly attached or taken down when desired. If the chair is

light and apt to tip over, make the rods long-enough to reach to the

floor.--Contributed by John V. Loeffler, Evansville, Ind.

Geometric Principle in Line Division

When sketching a plan, if any one of the first few lines drawn is found

to be the proper length, then this line can be made into a scale by the

geometric rule for dividing a given line into equal parts.

[Illustration: A Scale can be Made for Use on Any Sized Sketch or Drawing]

Suppose, for example, the line AB, which is to represent 12 ft., is found

to be 1 ft. long. Draw a line, AC, at any angle from the point A and step

off on it 12 equal parts, beginning at A. The last point, or the one at

C, is connected to the end B, then eleven other lines are drawn parallel

with CB. Thus AB will make a scale of 1 in. to each 1 ft.--Contributed by

Repairing a Broken Whip

Procure a piece of thin tin--the metal taken from a discarded fruit can

will do--and cut it about 2-1/2 in. long and wide enough to encircle

the break. Notch the ends like saw teeth and remove any sharp edges

with a file. Place the tin on the break and tie temporarily. Wind the

whole from end to end with a waxed linen thread, such as used by harness

makers. The threads lying alternately on the whip and on metal at the

notched ends eliminate any possibility of the parts working loose. A

break near the small and flexible end of a whip is repaired in the same

manner, using a quill instead of the tin. In either case, do not let the

edges of the splicing material meet, and it will clamp tightly on the

whip.--Contributed by W. S. Kingsley, W. Gouldsboro, Me.

Repairing a Worn Thimble

Silver thimbles are easily worn through at the end, and they can be

quickly repaired by soldering from the inside. A very neat repair can be

made with an alcohol lamp and a blowpipe by using a little silver solder.

Borax or resin is used as a flux.

A Small Torch

A small torch, that will give a very fine and hot smokeless flame, can

be made from a piece of glass tube, about 4 in. long, and 4 ft. of rubber

tubing. The glass tube is heated in the center until it is red, then the

ends drawn apart so that the tube will have a small diameter. After the

glass has cooled, make a small scratch with a file on the thin part and

break it. One of the pointed ends is connected to a straight piece of

glass tube with a short piece of the rubber tube, as shown in the sketch.

A small hole is cut in the side of the piece of rubber to admit air to

the gas. The torch is connected to an ordinary gas jet.--Contributed by

E. K. Marshall, Oak Park, Ill.

Fountain Attachment for an Ordinary Pen

A quite efficient fountain pen may be quickly made by bending an ordinary

pen, as shown at A, and inserting it in the holder opposite to the

regular pen, as shown at B. For best results, the point of the auxiliary

pen should just touch the regular pen.--Contributed by Thos. L. Parker,

Wibaux, Mont.

A little water added to oil paint will make a flat or

lusterless finish and will do no harm to the paint,

as the water evaporates in time.

Homemade Cut Press

The person who has a little ability in making wood cuts with a knife will

find it very interesting to make the press shown in the sketch. A fair

job of printing can be done with the press, using printer's ink spread on

a piece of glass with a hand ink roller, such as can be purchased cheaply

of any dealer in printing supplies.

[Illustration: A Hand Press for Printing from Cuts Made of Wood, Using

Ordinary Printer's Ink]

The press may have a base, A, of any size to suit, but one 1-1/2 in.

thick, 6 in. wide, and 12 in. long will be found to serve best for most

purposes. It must be smooth and level. Hard wood, such as maple, beech,

or birch, is best for all parts. The post B is 1-1/4 in. thick, 2 in.

wide, and 5 in. long. Before setting it, slot the upper end for the end

of the lever. This is done by making a saw cut, 1-3/4 in. deep, 5/8 in.

from either side and cutting out the core to make a slot 3/4 in. wide. A

1/4-in. hole is then bored through the prongs to receive a stove bolt that

connects them with the lever. The post is fastened with screws and glue

in a notch cut in the center of the base end.
