The _Point-Screw_ marked f is made of Iron; It hath a thin Head about

an Inch square, And a square Shank just under the Head, an Inch deep,

and almost quarter and half quarter Inch square, that the square Notch

in the hinder end of the Plate may slide on it from end to end of the

Notch; Under this square Shank is a round Pin filed with a Male-Screw

upon it, to which is fitted a _Nut_ with a Female-Screw in it, and Ears

on its outside to twist about, and draw the Head of the Shank close

down to the _Tympan_, and so hold the _Point-Plate_ fast in its Place.

¶. 20. _Of the_ Hammer, _described at_ h, _and_ Sheeps-Foot _described

at_ i _in Plate_ 9.

The _Hammer_ is a common _Hammer_ about a quarter of a Pound weight; It

hath no _Claws_ but a _Pen_, which stands the _Press-man_ instead when

the _Chase_ proves so big, that he is forced to use small _Quoins_.

The Figure of the _Sheeps-Foot_ is description sufficient. Its use is

to nail and un-nail the _Balls_.

The _Sheeps-Foot_ is all made of Iron, with an Hammer-head at one end,

to drive the _Ball-Nails_ into the _Ball-Stocks_, and a Claw at the

other end, to draw the _Ball-Nails_ out of the _Ball-Stocks_.

¶. 21. _Of the_ Foot-step, Girts, Stay _of the_ Carriage, Stay _of the_

Frisket, Ball-Stocks, Paper-Bench, Lye-Trough, Lye-Brush, Lye-Kettle,

Tray _to_ wet Paper _in_, Weights to Press Paper, Pelts, _or_ Leather,

Wool _or_ Hair, Ball-Nails _or_ Pumping-Nails.

The _Foot-Step_ is an Inch-Board about a Foot broad, and sixteen

Inches long. This Board is nailed upon a piece of Timber about seven

or eight Inches high, and is Bevil’d away on its upper-side, as is

also the Board on its under-side at its hither end, that the Board may

stand aslope upon the Floor. It is placed fast on the Floor under the

Carriage of the Press. Its Office shall be shewed when we come to treat

of Exercise of the _Press-man_.

_Girts_ are Thongs of Leather, cut out of the Back of an Horse-hide,

or a Bulls hide, sometimes an Hogs-hide. They are about an Inch and

an half, or an Inch and three quarters broad. Two of them are used to

carry the _Carriage_ out and in. These two have each of them one of

their ends nailed to the _Barrel_ on the _Spindle_ of the _Rounce_,

and the other ends nailed to the _Barrel_ behind the _Carriage_ in the

_Planck_ of the _Coffin_, and to the _Barrel_ on the fore-end of the

Frame of the _Coffin_.

The _Stay_ of the _Carriage_ is sometimes a piece of the same _Girt_

fastned to the outside of the further _Cheek_, and to the further

hinder side of the Frame of the _Carriage_. It is fastned at such a

length by the _Press-man_, that the _Carriage_ may ride so far out, as

that the Irons of the _Tympan_ may just rise free and clear off the

fore-side of the _Plattin_.

Another way to stay the _Carriage_ is to let an Iron Pin into the

upper-side of the further Rail of the Frame of the _Ribs_, just in the

place where the further hinder Rail of the _Carriage_ stands projecting

over the _Rib-Rail_, when the Iron of the _Tympan_ may just rise free

from the Fore-side of the _Plattin_; for then that projecting will stop

against the Iron Pin.

The _Stay_ of the _Frisket_ is made by fastning a Batten upon the

middle of the Top-side of the _Cap_, and by fastning a Batten to the

former Batten perpendicularly downwards, just at such a distance, that

the upper-side of the _Frisket_ may stop against it when it is turned

up just a little beyond a Perpendicular. When a _Press_ stands at a

convenient distance from a Wall, that Wall performs the office of the

aforesaid _Stay_.

_Ball-Stocks_ are Turn’d of _Alder_ or _Maple_. Their Shape is

delineated in Plate 9. at g: They are about seven Inches in Diameter,

and have their under-side Turned hollow, to contain the greater

quantity of _Wool_ or _Hair_, to keep the _Ball-Leathers_ plump the

longer.

The _Lye-Trough_ (delineated in Plate 9. at k) is a Square Trough made

of Inch-Boards, about four Inches deep, two Foot four Inches long,

and one Foot nine Inches broad, and flat in the Bottom. Its inside is

Leaded with Sheet-Lead, which reaches up over the upper Edges of the

_Trough_. In the middle of the two ends (for so I call the shortest

sides) on the outer-sides as _a a_, is fastned a round Iron Pin, which

moves in a round hole made in an Iron Stud with a square Sprig under

it, to be drove and fastned into a _Wooden Horse_, which _Horse_ I need

not describe, because in Plate aforesaid I have given you the Figure of

it.

The _Paper-Bench_ is only a common Bench about three Foot eight Inches

long, one Foot eight Inches broad, and three Foot four Inches high.

The _Lye-Brush_ is made of _Hogs-Bristles_ fastned into a Board with

Brass-Wyer, for durance sake: Its Board is commonly about nine Inches

long, and four and an half Inches broad; and the length of the Bristles

about three Inches.

To perform the Office of a _Lye-Kettle_ (which commonly holds about

three Gallons) the old-fashion’d _Chafers_ are most commodious, as well

because they are more handy and manageable than _Kettles_ with Bails,

as also because they keep _Lye_ longer hot.

The _Tray_ to _Wet Paper_ in is only a common Butchers Tray, large

enough to _Wet_ the largest _Paper_ in.

The _Weight_ to _Press Paper_ with, is either Mettal, or Stone, flat on

the Bottom, to ly steddy on the _Paper-Board_: It must be about 50 or

60 pound weight.

For _Pelts_ or _Leather_, _Ball-Nails_ or _Pumping-Nails_, _Wool_ or

_Hair_, _Vellom_ or _Parchment_ or _Forrel_, the _Press-man_

generally eases the _Master-Printer_ of the trouble of choosing, though

not the charge of paying for them: And for _Paste_, _Sallad Oyl_, and

such accidental Requisites as the _Press-man_ in his work may want, the

_Devil_ commonly fetches for him.

¶. 22. _Of_ Racks _to Hang_ Paper _on, and of the_ Peel.

Our Master-_Printer_ must provide _Racks_ to hang _Paper_ on to _Dry_.

They are made of Deal-board Battens, square, an Inch thick, and an

Inch and an half deep, and the length the whole length of the Deal,

which is commonly about ten or eleven Foot long, or else so long as

the convenience of the Room will allow: The two upper corners of these

_Rails_ are rounded off that they may not mark the _Paper_.

These _Racks_ are Hung over Head, either in the _Printing-House_, or

_Ware-house_, or both, or any other Room that is most convenient to

_Dry Paper_ in; they are hung athwart two _Rails_ an Inch thick, and

about three or four Inches deep, which _Rails_ are fastned to some

Joysts or other Timber in the Ceiling by Stiles perpendicular to the

Ceiling; These _Rails_ stand so wide assunder, that each end of the

_Racks_ may hang beyond them about the distance of two Foot, and have

on their upper edge at ten Inches distance from one another, so many

square Notches cut into them as the whole length of the _Rail_ will

bear; Into these square notches the _Racks_ are laid parallel to each

other with the flat side downwards, and the Rounded off side upwards.

The _Peel_ is described in Plate 9. at l, which Figure sufficiently

shews what it is; And therefore I shall need say no more to it, only

its Handle may be longer or shorter according as the height of the Room

it is to be used in may require.

¶. 23. _Of_ Inck.

The providing of good _Inck_, or rather good _Varnish_ for _Inck_, is

none of the least incumbent cares upon our _Master-Printer_, though

Custom has almost made it so here in _England_; for the process of

making _Inck_ being as well laborious to the Body, as noysom and

ungrateful to the Sence, and by several odd accidents dangerous of

Firing the Place it is made in, Our _English Master-Printers_ do

generally discharge themselves of that trouble; and instead of having

good _Inck_, content themselves that they pay an _Inck-maker_ for good

_Inck_, which may yet be better or worse according to the Conscience of

the _Inck-maker_.

That our Neighbours the _Hollanders_ who exhibit Patterns of good

_Printing_ to all the World, are careful and industrious in all the

circumstances of good _Printing_, is very notorious to all Book-men;

yet should they content themselves with such _Inck_ as we do, their

Work would appear notwithstanding the other circumstances they observe,

far less graceful than it does, as well as ours would appear more

beautiful if we used such _Inck_ as they do: for there is many Reasons,

considering how the _Inck_ is made with us and with them, why their

_Inck_ must needs be better than ours. As _First_, They make theirs

all of good old _Linseed-Oyl_ alone, and perhaps a little _Rosin_ in

it sometimes, when as our _Inck-makers_ to save charges mingle many

times _Trane-Oyl_ among theirs, and a great deal of _Rosin_; which

_Trane-Oyl_ by its grossness, Furs and Choaks up a _Form_, and by its

fatness hinders the _Inck_ from drying; so that when the Work comes

to the _Binders_, it _Sets off_; and besides is dull, smeary and

unpleasant to the Eye. And the _Rosin_ if too great a quantity be put

in, and the _Form_ be not very _Lean Beaten_, makes the _Inck_ turn

yellow: And the same does New _Linseed-Oyl_.

_Secondly_, They seldom _Boyl_ or _Burn_ it to that consistence the

_Hollanders_ do, because they not only save labour and Fewel, but have

a greater weight of _Inck_ out of the same quantity of _Oyl_ when less

_Burnt_ away than when more _Burnt_ away; which want of Burning makes

the _Inck_ also, though made of good old _Linseed-Oyl_ Fat and Smeary,

and hinders its _Drying_; so that when it comes to the _Binders_ it

also _Sets off_.

_Thirdly_, They do not use that way of clearing their _Inck_ the

_Hollanders_ do, or indeed any other way than meer Burning it, whereby

the _Inck_ remains more _Oyly_ and _Greasie_ than if it were well

clarified.

_Fourthly_, They to save the _Press-man_ the labour of _Rubbing_ the

_Blacking_ into _Varnish_ on the _Inck-Block_, _Boyl_ the _Blacking_ in

the _Varnish_, or at least put the _Blacking_ in whilst the _Varnish_

is yet _Boyling-hot_, which so _Burns_ and _Rubifies_ the _Blacking_,

that it loses much of its brisk and vivid black complexion.

_Fifthly_, Because _Blacking_ is dear, and adds little to the weight

of _Inck_, they stint themselves to a quantity which they exceed not;

so that sometimes the _Inck_ proves so unsufferable _Pale_, that the

_Press-man_ is forc’d to _Rub_ in more _Blacking_ upon the _Block_; yet

this he is often so loth to do, that he will rather hazard the content

the Colour shall give, than take the pains to amend it: satisfying

himself that he can lay the blame upon the _Inck-maker_.

Having thus hinted at the difference between the _Dutch_ and _English

Inck_, I shall now give you the Receipt and manner of making the

_Dutch-Varnish_.

They provide a _Kettle_ or a _Caldron_, but a _Caldron_ is more proper,

such an one as is described in Plate 9. at m. This Vessel should hold

twice so much _Oyl_ as they intend to _Boyl_, that the _Scum_ may be

some considerable time a _Rising_ from the top of the _Oyl_ to the top

of the Vessel to prevent danger. This _Caldron_ hath a Copper Cover to

fit the Mouth of it, and this Cover hath an Handle at the top of it to

take it off and put it on by. This _Caldron_ is set upon a good strong

Iron _Trevet_, and fill’d half full of old _Linseed-Oyl_, the older

the better, and hath a good Fire made under it of solid matter, either

_Sea Coal_, _Charcoal_ or pretty big Chumps of Wood that will burn well

without much Flame; for should the Flame rise too high, and the _Oyl_

be very hot at the taking off the Cover of the _Caldron_, the fume of

the _Oyl_ might be apt to take Fire at the Flame, and endanger the loss

of the _Oyl_ and Firing the House: Thus they let _Oyl_ heat in the

_Caldron_ till they think it is Boyling-hot; which to know, they peel

the outer Films of an _Oynion_ off it, and prick the _Oynion_ fast upon

the end of a small long Stick, and so put it into the heating _Oyl_:

If it be Boyling-hot, or almost Boyling-hot, the _Oynion_ will put the

_Oyl_ into a Fermentation, so that a Scum will gather on the top of the

_Oyl_, and rise by degrees, and that more or less according as it is

more or less Hot: But if it be so very Hot that the Scum rises apace,

they quickly take the _Oynion_ out, and by degrees the Scum will fall.

But if the _Oyl_ be Hot enough, and they intend to put any _Rosin_

in, the quantity is to every Gallon of _Oyl_ half a Pound, or rarely

a whole Pound. The _Rosin_ they beat small in a _Mortar_, and with an

Iron Ladle, or else by an Handful at a time strew it in gently into

the _Oyl_ lest it make the Scum rise too fast; but every Ladle-full or

Handful they put in so leasurely after one another, that the first must

be wholly dissolv’d before they put any more in; for else the Scum will

Rise too fast, as aforesaid: So that you may perceive a great care

is to keep the Scum down: For if it Boyl over into the Fire never so

little, the whole Body of _Oyl_ will take Fire immediately.

If the _Oyl_ be Hot enough to _Burn_, they _Burn_ it, and that so often

till it be _Hard_ enough, which sometimes is six, seven, eight times,

or more.

To _Burn_ it they take a long small Stick, or double up half a Sheet of

Paper, and light one end to set Fire to the _Oyl_; It will presently

Take if the _Oyl_ be Hot enough, if not, they Boyl it longer, till it

be.

To try if it be _Hard_ enough, they put the end of a Stick into the

_Oyl_, which will lick up about three or four drops, which they put

upon an Oyster-shell, or some such thing, and set it by to cool, and

when it is cold they touch it with their Fore or Middle-Finger and

Thumb, and try its consistence by sticking together of their Finger

and Thumb; for if it draw stiff like strong _Turpentine_ it is Hard

enough, if not, they Boyl it longer, or _Burn_ it again till it be so

consolidated.

When it is well Boyled they throw in an Ounce of Letharge of Silver to

every four Gallons of _Oyl_ to Clarifie it, and Boyl it gently once

again, and then take it off the Fire to stand and cool, and when it

is cool enough to put their Hand in, they Strain it through a Linnen

Cloath, and with their Hands wring all the _Varnish_ out into a Leaded

Stone Pot or Pan, and keeping it covered, set it by for their use; The

longer it stands by the better, because it is less subject to turn

Yellow on the Paper that is Printed with it.

This is the _Dutch_ way of making _Varnish_, and the way the English

_Inck-makers_ ought to use.

_Note_, _First_, That the _Varnish_ may be made without _Burning_ the

_Oyl_, _viz._ only with well and long Boyling it; for _Burning_ is but

a violent way of Boyling, to consolidate it the sooner.

_Secondly_, That an _Apple_ or a _Crust_ of _Bread_, _&c._ stuck upon

the end of a Stick instead of an _Oynion_ will also make the Scum of

the _Oyl_ rise: For it is only the Air contained in the Pores of the

_Apple_, _Crust_ or _Oynion_, &c. pressed or forced out by the violent

heat of the _Oyl_, that raises the many Bubbles on the top of the

_Oyl_: And the connection of those Bubbles are vulgarly called _Scum_.

_Thirdly_, The English _Inck-makers_ that often make _Inck_, and that

in great quantities, because one Man may serve all _England_, instead

of setting a _Caldron_ on a _Trevet_, build a _Furnace_ under a great

_Caldron_, and Trim it about so with Brick, that it Boyls far sooner

and more securely than on a _Trevet_; because if the _Oyl_ should

chance to Boyl over, yet can it not run into the Fire, being Fenced

round about with Brick as aforesaid, and the _Stoking-hole_ lying far

under the _Caldron_.

_Fourthly_, When for want of a _Caldron_ the _Master-Printer_ makes

_Varnish_ in a _Kettle_, He provides a great piece of thick _Canvass_,

big enough when three or four double to cover the _Kettle_, and also

to hang half round the sides of the _Kettle_: This _Canvass_ (to make

it more soluble) is wet in Water, and the Water well wrung out again,

so that the _Canvass_ remains only moist: Its use is to throw flat

over the Mouth of the _Kettle_ when the _Oyl_ is _Burning_, to keep

the smoak in, that it may stifle the Flame when they see cause to put

it out. But the Water as was said before, must be very well wrung out

of the _Canvass_, for should but a drop or two fall from the sides of

it into the _Oyl_ when it is Burning, it will so enrage the _Oyl_, and

raise the Scum, that it might endanger the working over the top of the

_Kettle_.

* * * * *

Having shewn you the _Master-Printers_ Office, I account it suitable

to proper Method, to let you know how the _Letter-Founder_ Cuts the

_Punches_, how the _Molds_ are made, the _Matrices_ Sunck, and the

_Letter Cast_ and _Drest_, for all these Operations precede the

_Compositers_ Trade, as the _Compositers_ does the _Press-mans_;

wherefore the next _Exercises_ shall be (God willing) upon _Cutting_ of

the _Steel-Punches_.

_MECHANICK EXERCISES:_

Or, the Doctrine of

=Handy-works.=

Applied to the Art of

=Letter-Cutting.=

_PREFACE._

LEtter-Cutting _is a Handy-Work hitherto kept so conceal’d among the

Artificers of it, that I cannot learn any one hath taught it any

other; But every one that has used it, Learnt it of his own Genuine

Inclination. Therefore, though I cannot (as in other Trades) describe

the general Practice of Work-men, yet the Rules I follow I shall shew

here, and have as good an Opinion of these Rules, as those have that

are shyest of discovering theirs. For, indeed, by the appearance of

some Work done, a judicious Eye may doubt whether they go by any Rule

at all, though Geometrick Rules, in no Practice whatever, ought to be

more nicely or exactly observed than in this._

§. 12. ¶. 1. _Of Letter-Cutters Tools._

The making of _Steel-Punches_ is a Branch of the _Smith_’s Trade:

For, as I told you in the Preface to _Numb._ 1. The _Black-Smith_’s

Trade comprehends all Trades that use either Forge or File, from the

_Anchor-Smith_, to the _Watch-maker_: They all working by the same

Rules, though not with equal exactness; and all using the same Tools,

though of different Sizes from those the Common _Black-Smith_ uses;

and that according to the various purposes they are applied, _&c._

Therefore, indeed, a _Letter-Cutter_ should have a Forge set up, as

by _Numb._ 1. But some _Letter-Cutters_ may seem to scorn to use a

Forge, as accounting it too hard Labour, and Ungenteel for themselves

to officiate at. Yet they all well know, that though they may have

a common _Black-Smith_ perform their much and heavy Work, that many

times a Forge of their own at Hand would be very commodious for them in

several accidental little and light Jobs, which (in a Train of Work)

they must meet withal.

But if our _Letter-Cutter_ will have no Forge, yet he must of necessity

accommodate himself with a _Vice_, _Hand-Vice_, _Hammers_, _Files_,

_Small_ and _Fine Files_ (commonly called _Watch-makers Files_) of

these he saves all, as they wear out, to smooth and burnish the Sides

and Face of his Letter with, as shall be shewed; _Gravers_, and

_Sculpters_ of all sorts, an _Anvil_, or a _Stake_, an _Oyl-stone_,

_&c._ And of these, such as are suitable and sizable to the several

Letters he is to Cut. These, or many of these Tools, being described

in _Numb._ 1. I refer my Reader thither, and proceed to give an account

of some Tools peculiar to the _Letter-Cutter_, though not of particular

use to the Common _Black-Smith_.

[Illustration: _Plate 10._]

¶. 2. _Of the_ Using-File.

This _File_ is about nine or ten Inches long, and three or four Inches

broad, and three quarters of an Inch thick: The two broad sides must

be exactly flat and straight: And the one side is commonly cut with a

_Bastard-Cut_, the other with a _Fine_ or _Smooth Cut_. (See _Numb._ 1.

_Fol._ 14, 15.) Its use is to _Rub_ a piece of Steel, Iron, or Brass,

_&c._ flat and straight upon, as shall be shewed hereafter.

In chusing it, you must see it be exactly Flat and Straight all its

Length and Breadth: For if it in any part Belly out, or be Hollow

inwards, what is Rubbed upon it will be Hollow, Rubbing on the Bellying

part; and Bellying, Rubbing on the Hollow part. You must also see that

it be very Hard; and therefore the thickest _Using-Files_ are likeliest

to prove best, because the thin commonly Warp in Hardning.

¶. 3. _Of the_ Flat-Gage.

The _Flat-Gage_ is described in _Plate_ 10. at A. It is made of a flat

piece of Box, or other Hard Wood. Its Length is three Inches and an

half, its Breadth two Inches and an half, and its Thickness one Inch

and an half. This is on the Flat, first made Square, but afterwards

hath one of its Corners (as _h_) a little rounded off, that it may the

easier comply with the Ball of the Hand. Out of one of its longest

Sides, _viz._ that not rounded off, is Cut through the thickness of it

an exact Square, whose one side _b f_, _c g_ is about an Inch and three

quarters long; and its other side _b d_, _c e_ about half an Inch long.

The Depth of these Sides and their Angle is exactly Square to the top

and bottom of the upper and under Superficies of the _Flat-Gage_.

Its Use is to hold a Rod of Steel, or Body of a _Mold_, _&c._ exactly

perpendicular to the Flat of the _Using-File_, that the end of it may

rub upon the _Using-File_, and be Filed away exactly Square, and that

to the Shank; as shall more at large be shewed in §. 2. ¶. 3.

¶. 4. _Of the_ Sliding-Gage.

The _Sliding-Gage_ is described in _Plate_ 10. at _Fig._ B. It is a

Tool commonly used by _Mathematical Instrument-Makers_, and I have

found it of great use in _Letter-Cutting_, and making of _Molds_, _&c._

_a a_ the Beam, _b_ the Tooth, _c c_ the Sliding Socket, _d d d d_ the

Shoulder of the Socket.

Its Use is to measure and set off Distances between the Sholder and the

Tooth, and to mark it off from the end, or else from the edge of your

Work.

I always use two or three of these _Gages_, that I need not remove the

Sholder when it is set to a Distance which I may have after-use for; as

shall in Working be shewed more fully.

¶. 5. _Of the_ Face-Gages, _marked_ C _in Plate 10._

The _Face-Gage_ is a Square Notch cut with a File into the edge of a

thin Plate of Steel, Iron, or Brass, the thickness of a piece of common

Latton, and the Notch about an _English_ deep. There be three of these

Gages made, for the Letters to be cut on one Body; but they may be all

made upon one thin Plate, the readier to be found, as at D. As first,

for the Long-Letters; Secondly, for the Assending Letters; And Thirdly,

for the Short-Letters. The Length of these several Notches, or Gages,

have their Proportions to the Body they are cut to, and are as follows.

We shall imagine (for in Practice it cannot well be perform’d, unless

in very large Bodies) that the Length of the whole Body is divided into

forty and two equal Parts.

The _Gage_ for the Long-Letters are the length of the whole Body,

_viz._ forty and two equal Parts. The _Gage_ for the Assending Letters,

_Roman_ and _Italica_, are five Seventh Parts of the Body, _viz._

thirty Parts of forty-two, and thirty and three Parts for _English_

Face. The _Gage_ for the Short-Letters are three Seventh Parts of the

whole Body, _viz._ eighteen Parts of forty-two for the _Roman_ and

_Italica_, and twenty two Parts for the _English_ Face.

It may indeed be thought impossible to divide a Body into seven

equal Parts, and much more difficult to divide each of those seven

equal Parts into six equal Parts, which are forty-two, as aforesaid,

especially if the Body be but small; but yet it is possible with

curious Working: For seven thin Spaces may be Cast and Rubb’d to do it.

And for dividing each of the thin Spaces into six equal Parts, you may

Cast and Rub Full Point . to be of the thickness of one thin Space,

and one sixth part of a thin Space: And you may Cast and Rub : to be

the thickness of one thin Space, and two sixth parts of a thin Space:

And you may Cast and Rub , to be the thickness of one thin Space, and

three sixth parts of a thin Space: And you may Cast and Rub - to be the

thickness of one thin Space, and four sixth parts of a thin Space: And

you may Cast and Rub ; to be the thickness of one thin Space, and five

sixth parts of a thin Space.

The reason why I propose . to be Cast and Rubb’d one sixth part thicker

than a thin Space, is only that it may be readily distinguished from :

, - ; which are two sixth parts, three sixth parts, four sixth parts,

five sixth parts thicker than a thin Space. And for six sixth parts

thicker than a thin Space, two thin Spaces does it.
