capacity with a given amount of power, more even grinding and better
yield, and lastly, but not less important, increased facility in
obtaining a perfect running balance. It will be observed that the runner
is supported upon a steel seat secured in the stone permanently--being
substantially the same in this respect as when the ordinary balance-iron
is used.
The power being transmitted to the stone by the adjustable part of the
iron and no weight upon any part of it, with the entire structure of the
form to give the greatest attainable firmness and durability, combine to
make it perfection as a driving iron, and it is accordingly in extensive
use, although no especial effort has been made until late for their
manufacture and sale. They are made in the best manner by skillful men
and machinery adapted for the purpose, the parts well fitted and turned
true inside where the grain enters and passes.
They are made of the following sizes: 8½, 10 and 12 inches diameter.
To order for attaching to stones with other irons already in, give
diameter of the eye in stone at the face.
Distance from the cock-head point to the lower side of the driver.
Shape of cock-head as near as you can.
Shape and exact size of spindle where your present driver goes on.
In getting the shape as well as size of place where your present driver
fits, it is a good plan to oil the inside surface of the hole in driver
(in which the spindle fits) and fill it with plaster, then take out and
send the cast by express. The shape of cock-head may be got by similar
process.
We will send necessary instructions, so that any one of medium skill can
put them in at the mill.
Give names, post office, county, and shipping point plainly, and how you
wish to pay us. Money sent by Post Office Order is safe, and payment
with the order always saves delay and trouble of making out bills,
book-entries, &c. To those whose faith is not sufficient, will send the
irons on trial or as circumstances best suggest at the time.
The safe arrival of them is guaranteed. Every iron is warranted.

[Illustration: Fig. 2.]
These two cuts are intended to represent the self-tram irons for our
under-runner mills. Fig. 1 shows the form of the outside, as it appears
before being bedded in the centre, and iron back of the runner stone.
Fig. 2 is a view of the inside, showing where the point of the spindle
and driver rest.
OIL BUSH.
[Illustration]
This cut is a sectional view of our improved oil bush. A shows the mill
spindle, B B, B B, is the collar or part that turns with the spindle and
is secured firmly to it. The parts E E E E, show the upwardly projecting
sleeve at some distance from and encircling the spindle or shaft, and
forms the inner wall of the oil chamber. C C C C are two of the four
followers or segments lined with the best anti-friction metal. The
wedges N N, are raised or lowered as circumstances require by the four
metal screws, two of them being shown at S S; by this means the
followers and spindle are adjusted with great precision. D D D D forming
the outer wall of the chamber, and E E E E its bottom and inner part,
gives us a complete oil well in which the followers, collar of spindle,
&c., are immersed. THE OPERATION is as follows: the rotating shaft or
spindle carries with it the collar or sleeve bearing and produces
centrifugal force in the chamber, by which the oil is driven up the
sides of the passages and followers; the bearing is thus made to move
constantly in oil. No oil can escape except when necessary to draw off
at the orifice provided with the thumb screw K, when a fresh supply is
needed. This simple self-oiling arrangement is the best thing in use for
fast running upright bearings of any kind.
BULLOCK’ MILL BUSH.
Patented December 31, 1867.
[Illustration: _Fig. 1_]
The object of the invention which is herewith illustrated, is to enable
the spindles of mill-stones to be adjusted with perfect accuracy, and at
the same time furnish bearings of anti-friction materials, which may be
kept constantly and perfectly lubricated, and from which all extraneous
dust or grit, calculated to aggravate friction, may be kept excluded.
Fig. 1 is a perspective view of this improvement, and Fig. 2 is a
sectional view of the same, showing details of construction. A, Fig. 2,
is the spindle, playing in segmental bearings B.
There are four of these, which, together, make up the entire bearing for
the spindle. They are hollow, as shown in the engraving, and faced with
anti-friction surfaces.
The outer sides of these segments are inclined, these surfaces resting
against the inclined inner surfaces of the hollow binding wedges C.
Through the lower part of these wedges pass hooked bolts, D, with thumb
nuts at their lower ends, by turning which the wedges are forced upward,
and the segments B being prevented from rising by the top plate E, are
forced inward till their surfaces are brought in proper proximity to the
spindle.
[Illustration: _Fig. 2_]
It is evident that by raising and lowering these wedges, as
circumstances require, the spindle can be adjusted with the greatest
accuracy.
Lubrication is secured by placing a store of oil, in the chambers F, of
the segmental bearings B, from which it is fed, as wanted, through the
apertures G, to the bearing surfaces of the spindle and bush. Lastly,
the exclusion of dust and grit is secured by forming a chamber H, upon
the top plate of the bush, with an annular cap which shuts down over it,
and encloses the spindle, in which chamber is placed packing yarn or
other suitable material to intercept all extraneous material of this
character.
The top plate is bolted down to the external portion of the bush, and
the whole enclosed, as shown in Fig. 1.
All experienced millers are aware that the attainment of the above
objects by a simple device is a very desirable achievement. By the use
of this improvement the adjustment can be readily and accurately made,
and the wear of the spindle is reduced to a minimum.
We can fit any size spindle from 3½ to 5 inches diameter, and have
three sizes of bushes, 7½, 8½ and 9½ inches square. In ordering
bushes, all that is necessary is to state the diameter of neck of
spindle and size of eye in bed stone, and the proper size bush will be
shipped. Satisfaction guaranteed.
We have some half dozen different patterns of bushes ranging in price
from $2 to $20--some having three and some four followers for wood or
metal.
Lighter Screws and Hand Wheels.
[Illustration]
These engravings illustrate the style of hand wheel and screw with cap
and washer that we make and furnish with our combined husk mills, and
when ordered we send them with the irons needed with mill stones. The
figure on the right shows the hand wheel, screw cap and washer in
position when ready for operation. The wrought iron screw is cut in a
lathe and is what is termed a square thread. The wheel cap and washer
are all turned and polished, making a good looking, durable fixture, as
well as an accurate means of adjusting the stone. We sometimes make
these of brass.
Lighter Levers and Arched Step.
[Illustration]
This shows our pattern for arched bridge pot and lighter lever for
geared mills or when an elevated step is wanted. The part holding the
steel on which spindle rests, is contained in a central lifting chamber,
which is turned to fit the body of the arch, like a piston, thus
allowing a perfect perpendicular movement without any liability to vary
from its true position; the heavy set-screw at the rear end of the lever
is to admit of more adjustment; the lever can be moved around at most
any required angle without interfering with any part of the step. We
provide means (not shown in this cut) to tram the spindle by screws
placed in the central lift part of the step, when desired.
Mill Steps.
Of these we have various styles, some sufficiently heavy for a six foot
mill stone, and to tram by screws. The centre lift part is constructed
in same style as the arch-step described above. We have patterns of all
lengths of lighter levers, as shown under head of Lighter Levers, which
fit over this style of step in same manner as shown, excepting we
provide an independent rest for the rear end of the lever and screw for
regulating it. This makes a very desirable rig for the lower end of mill
spindles in any mill, and are fast taking the place of all others. It
obviates the cutting of the bridge-tree or timber on which it rests.
The steel on which the spindle-toe rests and presses sidewise in running
is constructed in various ways. In some situations we provide a flat
plate, below for taking the downward pressure, and above it a heavy
steel ring supported a little above to allow a chamber for the flow of
oil around the very extreme lower end of the steel spindle toe. This
chamber is free to be supplied with oil from the upper receptacle
through holes provided for the purpose. A bearing made with a hardened
steel plate below and a ring of good anti-friction metal around the
spindle-toe is the most desirable when properly constructed and of
suitable metals.
MILL CURBS AND HOOPS.
[Illustration: Fig. 1.]
Of all the various styles and sizes we are better prepared to make than
any other establishment we know of in the United States. We keep on hand
large quantities of the material of which they are made so that it may
be thoroughly seasoned before use. Their construction is as follows: the
tops are made of double-thickness lapped and tongued and screwed
together. The body is made of pine staves, worked on a double-headed
tongueing and grooving machine made for this purpose, with their
mandrels in radius positions to make a close fitting joint for any size
we choose to make; the outside bands are of black walnut, under which we
place neat iron bands, one at the base and one near the top, under the
projecting curb or top. For protecting the wood from being affected, we
coat the inside with white lead paint, and give the outside three coats
of good varnish. In the preparation to ship them and keep every part
from the liability of damaging in the least, we make a complete
protection of a light frame work and circle pieces surrounding the
whole. When the hopper frame and feed rig is ordered we place them
inside. This not only makes a strong and durable cover to the
mill-stone, but one that for style of finish and attractive appearance
pleases all.
Silent Feeders.
[Illustration: Fig. 2.]
Of these we make some half a dozen kinds, differing somewhat in
construction and appearance, some of which are shown in the accompanying
cuts. Fig. 1 is of the style known as “the glass globe tripod.” The
globe is made of the best clear flint glass from one-fourth to one-half
inch in thickness. The iron frame can be lifted from its bearings on the
curb at any time. The hand wheel and screw by which the feed to the
stone is regulated, is provided with a spring so that by pressing upon
the wheel the feed tube can be suddenly raised if necessary, when by the
action of the spring it will take its exact position as before. All the
parts are carefully fitted up, the hand wheel and such other parts
turned as necessary to complete it in a tasteful manner.
[Illustration:
Fig. 3.
]
With those shown in Figs. 2 and 3 we make large or small conical
hoppers, of heavy tin, galvanized iron or brass. The feed rig shown in
Fig. 3 is called the Bracket Rig. The feed wheel is turned, and all
fitted up in same manner as the others, and suits more millers for
custom and merchant mills than the other styles. Those however which are
most frequently wanted is this bracket rig with the ordinary wooden
hopper and frame, after the style shown upon the mill on page 17. If a
feed attachment is wanted, with shoe and damsel for feeding corn, mixed
feed, &c., we usually send the kind shown on the mill, page 14. In all
cases where orders are given for any kind of a feed attachment for mill
stones, we must know the size of top of curb, size of opening in it and
distance from top of bail or balance iron to top of said curb, size of
eye in stone, and when feed plate is wanted, give width of said balance
bail, and if there is anything projecting above it, give its size and
shape, so that we can fit the feed plate, damsel or what may be ordered,
to it.
Proof Staff.
[Illustration]
To promptly and satisfactorily fill all orders in this line we keep on
hand a complete assortment. The use of this article in a mill of two or
more run of stones is not as fully appreciated as it should be; we do
not see how a miller can well get along without it.
The kind we furnish we think are the best in the market, exactly true,
made of the best shape to retain a true face, provided with a spirit
level in the back; for correctness no other can excel it, and the whole
is placed in a close fitting, nicely finished box. Three sizes are made,
see list.
Red Staffs.
[Illustration]
These articles of the various sizes used in flour mills we make of the
best entirely dry and seasoned cherry lumber. The stuff is prepared by
suitable machinery, every piece carefully fitted, then secured by glue
and screws, the latter liberally put in. Both the staff and box are
finished in neat style, well varnished, and sold at a price that will
not pay for making them at the mill, unless the material was at hand and
advantages better than usual.
Mill Picks.
[Illustration]
We have under our constant employ pick makers that know their business,
and we are having imported for this purpose a brand of English steel
made expressly for mill stone picks. We make three sizes with eyes,
unless otherwise ordered, as follows: light cracking, heavy cracking and
furrowing. (See price list for prices, weight, &c.) If any points
should prove defective (as will occasionally happen) do not have any
other maker or smith work on them, but return to us and we will make it
satisfactory, and send back at once, as we warrant every one. We have
ready for shipment several patent picks, some of which we have tested
and describe as follows:
Cumming’ Pick.
[Illustration: Fig. 1.]
Description.
[Illustration: Fig. 2.]
[Illustration: Fig. 3.]
Fig. 1 represents the entire Pick ready for use. In Fig. 2 the pick or
blade is shown in connection with the clamp-bar. While in Fig. 3 is
given a complete sectional view of all parts of the device. In this Fig.
C C represents the head or stock, and G the clamp-bar with its
wedge-shaped head H. At K is shown the blade with its upper end bent to
fit the notches in the clamp-bar. The device is perfect without the set
screw F.
In adjusting for use the blade is placed upon the clamp-bar as shown in
Fig. 2, and both are inserted within the socket of the pick-head; they
are driven firmly into the socket by using. It will be seen that the
more powerful the blows upon the stone the more securely is the blade
confined within its socket, resulting from the wedge-like form of the
clamp-bar. While to remove the blade reverse the pick and strike the
opposite end of the clamp-bar on any solid substance, (a small piece of
iron placed on the face of the mill stone is most suitable,) when the
bar and blade will be instantly released, and another blade can be
readily inserted. The blades being of a uniform thickness and temper
only require grinding to sharpen. The wearing portion of each blade is
3½ inches; as they are worn by use they can be let down in the
ratchet. Ten blades furnished with each.
Crossley’ Pick.
[Illustration: _Fig. 1_]
[Illustration: _Fig. 2_]
Fig. 1 is a perspective view, and Fig. 2 a sectional view.
This improvement supplies a want long felt by millers, more especially
those who have not the convenience of sending their picks to a good
blacksmith who understands tempering steel.
A is a wedge-shaped plate, which is attached to the handle by a screw
shank; B is a piece of metal made so as to partly fold about A, as
shown, but leaving a space between A and B, in which the steel bit C is
held by a lug formed upon it, which fits into a corresponding recess in
the plate B, as shown in the section, Fig. 2.
It results from this arrangement that blows upon the bit C, in dressing
a stone, more firmly clamp and hold the parts together, while to loosen
them, all that is necessary is to tap the plate B on the end opposite
the cutting point or edge, which unwedges the two plates and releases
the bit.
Two recesses are provided in the plate B, so that when the bit is worn
down it can be set further out from between the plates A and B. When one
end of the bit becomes so worn as to be no longer available, the bit is
reversed, and the other end applied to dressing the stone. Thus the bit
may be used until it is almost entirely worn away. It is retained
firmly, and yet is instantly detached for sharpening or for adjustment.
The head is made of Malleable Iron, and the blades of the _very best
quality hammered cast steel_, tempered the whole length, and do not
require blacksmithing, but only to be ground when dull.
The price places these Picks within the reach of every miller.
Twelve 6 inch double blades sent with each head.
Hoisting Screw, Wrench, Bails and Pins.
[Illustration]
We are well prepared for making the above articles and have all ordinary
sizes on hands ready for use. The outfit is of the very best material;
the wrench, screw, &c., is of wrought iron, and together with all the
parts is in fine proportion and of great strength.
Damsels.
These we generally make to order, but we keep at all times a few of such
as are mostly called for.
Those with from three to five beaters, with staff, and all wrought
iron, are mostly ordered for merchant and sometimes custom mills. We
have a variety of patterns for cast iron damsels with oval beating part.
We turn and polish both kinds so as to make a neat and useful article.
In ordering these some needed dimensions are necessary to enable us to
meet expectations.
[Illustration]
ELEVATORS.
[Illustration: Fig. 1.]
This engraving represents the head and part of the trunk of an Elevator,
or what is termed an elevator head; Fig. 2 (on next page) represents the
elevator foot. An elevator head and foot as furnished by us includes
Fig. 1 and Fig. 2 with turned iron pulleys in them, the necessary
shafting, and an outside bevel or spur gear wheel or turned pulley to
receive power for driving the Elevator.
NOTE.--The iron spider as represented leaning against the Elevator head
(Fig. 1) has no connection with any part of it except to show the shape
of our patterns in that line.
[Illustration: Fig. 2.]
Elevator Cups (IMPROVED.)
Of all the sizes required for any kind of an elevator we make in our
establishment. Having long employed a workman on this work with special
machinery of our own, and as we buy the stock in large quantities, we
are as well equipped as it is possible to be for making this useful
appendage of a flour mill. Their advantages are: durability and economy,
the different sizes are perfectly uniform, of the smaller and medium
sizes the body is made of heavy tin, and all having an iron band neatly
and skilfully secured around the upper edge. It makes a thoroughly
strong, smooth, at the same time a light cup, and offering the least
resistance in passing through the grain of any cup now offered.
They are less liable to catch on the sides of the Elevator trunking, and
no breaking and tearing as is common to the cheap wired or rough iron
cups secured to the belt in the ordinary manner. Cheap cups made in the
usual style, wired tops, for old mills and repair jobs, constantly on
hand.
Our Improved Fastening.
This is of special advantage, has been used since 1869, and all who use
and see it pronounce it vastly superior. It is a copper clasp nicely
contrived to firmly clamp the bucket to the belt. It perforates the belt
and cup through two or three slotted openings. The cup can be easily
removed from the belt; it does not cut the belt so as to weaken it; it
prevents the cups from tipping as they pass down. The expense is some
more than screws, but those having put up common warehouse elevators
with this fastening, think it the cheapest article in use.
Bag Trucks.
[Illustration]
The frequent calls for this useful article has induced us to prepare for
and make them in large quantities, until we find ourselves supplying the
leading retail and jobbing houses of the west cheaper than they have
been heretofore supplied by eastern makers. It is a better constructed
and more desirable tool than will generally be found. We make a box
truck also, similar in style.
Conveyor Flights.
Of all sizes required, made of sugar or maple lumber. They are smooth,
uniform and of desirable shape. In ordering, give dimensions of face or
front of flight and size of hole you intend driving the tenon into;
also, the size and kind of wood the shaft is made of.
BUCKWHEAT BOLTS.
We make these of various sizes. Some are wanted to make flour rapidly
for some particular markets, and require to be of large size, with
medium fine cloth. Those in most common demand are for custom mills and
of two sizes: one with 8 feet, and one with 10 feet reels in complete
chests with conveyor and necessary cut-offs for changing grade of flour;
a shaft with coupling, and outside pulley or pair of bevel gear wheels
is furnished, so that it can be driven from either end. Every thing is
done to facilitate the convenience of setting up and attaching power.
The cloth is made up of “Dufour & Co.’s best Dutch Anchor,” to fit the
reel, and of proper numbers for the work required. When a bolt is wanted
for this purpose we should know the capacity required of it, &c.
Meal Bolts.
These are made in chests with conveyor, cut-offs, &c., as described
under head of “Buckwheat Bolts.” Cloth adapted to requirements, either
of wire or silk. These are of two sizes, 5½ and 8 feet reels.
Belting.
“A good belt is what I want,” is the remark often made, and to supply
our already large trade in this line, we have made the necessary
arrangements to ship on call what may be wanted at the lowest rates. In
ordering, it is well to state the purpose for which it is wanted. For
elevators, we recommend leather belting; when something cheaper is
wanted, we furnish three-ply cotton duck. It is not so durable, but is
firm, and strong as any gum belt, and answers a good purpose for a cheap
warehouse, meal or feed elevator.
Perforated Zinc, Tin, Iron or Steel Plates.
Of most all sizes and shapes of holes for zig-zags. Riddles, malt-kiln
floors, corn screen, and smut mill jackets furnished at low rates.
Screen Wire.
For wheat screen, meal bolts, &c., from number 2 to 24 meshes to the
inch, most all widths, in any quantity desired. Wire is even and good
size to form a strong fabric.
Duster Wire.
English and American wire for bran-dusters, 9 inches wide. The kinds
mostly in demand we keep in stock.
NOTE.--In ordering perforated plates or woven wire, it is best to give
us as much time as possible, as it is impossible to keep made up and in
stock all the kinds wanted.
PRICES, TERMS AND WEIGHTS.
From our price list, although full and explanatory, it is difficult for
some to get a clear understanding, especially when a complete outfit is
wanted, including every iron, belt, &c., to attach power; therefore,
write us stating clearly as possible your wants, when we will make a
proposal of cost. We will send our printed weight and price list, when
required.
As a rule when our customer is ready to order, or on our commencing the
work and making it ready for shipment, we require a payment of from
one-eighth to one-half of the whole amount, and settlement on or before
delivery, which is when a shipping receipt is taken, as the work then
passes into the ownership of the purchaser. By special arrangement we
often ship to the care of some satisfactory person or firm who will
receive and make settlement for the supplies. This person may reside at
or near to the point of destination. Do not think us exacting; all we
want is an equivalent for our products and some reasonably safe means of
getting it.
