page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SLATER, of Mosney, in the County Palatine of Lancaster, Callicoe Printer,
send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent, under His Seal appointed for that purpose, bearing date
at Westminster, the Twenty-ninth day of April last, give and grant unto me,
the said John Slater, my executors, administrators, and assigns, His especial
licence, full power, sole privilege, and authority, that I, my executors,
administrators, or assigns, might make, use, exercise, and vend, within that part
of Great Britain called England, the Dominion of Wales, and the Town
of Berwick-upon-Tweed, my Invention of "A NEW MACHINE FOR PRINTING
ONE, TWO, THREE, OR MORE COLOURS ON COTTONS, CALLICOES, MUSLINS, LINENS,
SILKS, STUFFS, DIMITIES, JEANS, VELVERETS, WOLLEN CLOTH, OR ANY OTHER
SPECIES OR KIND OF MANUFACTURED GOODS WHATSOEVER," for the term of fourteen
years from the date thereof; in which said Letters Patent is contained a
proviso oblidging me, the said John Slater, particularly to describe and ascer-
tain the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, and to
cause the same to be inrolled in His Majesty's High Court of Chancery
within four callender months immediately after the date of the same Letters
Patent, as by such Letters Patent, reference being thereunto had, may more
fully at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Slater, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described and
ascertained as follows, that is to say :-
It consists in the using, for the purpose of so printing as aforesaid, the
machine or piece of machinery particularly described in the Plan hereunto
annexed or hereunder drawn, and which machine or piece of machinery con-
sists of the several parts, and is to be constructed, put together, and used, in
the manner described in the said Plan, and the explanation subjoined hereto,
and which machine, and the rollers contained therein, may be made of wood,
copper, iron, pewter, or any other kind of metal or materials whatsoever of
which rollers are or can be made.
In witness whereof, I, the said John Slater, have hereunto set my hand
& seal, the Twenty-first day of August, in the twenty-fourth year of
the reign of His said Majesty King George the Third, and in the
year of our Lord One thousand seven hundred and eighty-four.
Figure 1st represents the machine. A, A, A, the frame of the machine.
B, B, the roll, covered with a piece of wollen cloth, against which the printing
rollers run, and are pressed to it by weights hung on their centers. C, C, C, C,
the colour rolls upon which the colours are put; those rolls run against the
printing rolls and furnish them with colour. D, D, D, D, are pieces of iron
in which the centers of the colour rolls C, C, C, C, run; they have skrews
at the bottom, and nutts at a, a, a, a, to raise or fall the colour rolls at pleasure.
E, E, E, is a semicircular piece of wood or iron fix'd to the frame; to this iron
and the frame are fixed pieces of iron with holes in, through which the pieces
of iron D, D, D, D, are put. F, F, the white cloth wound on a roll ready
for printing. G, the cloth going to be printed. H, H, H, the cloth coming
from the machine printed. K, K, K, three rolls betwixt which the printed
cloth passes; those rolls are pressed together by weights or skrews, and turned
by the handle L. Those rolls, after the cloth is put betwixt 'em, and the
handle moved, gives motion to the whole. 0, 0, 0, 0, are wheels fixed on
the ends of the printing rolls. P, P, P, P, are intermediate wheels (fixed on

page_text: immoveable pivots) into which the wheels on the ends of the printing rolls
strike. The use of those wheels is to keep the printing rolls from overrunning
each other. This may also be done by a large wheel on the end of the roll B, B.
R, a piece of iron or wood hanged to the end of the frame, and put in a grove
in the cloth roll to keep it in its place.
Figure 2nd. B, B, B, is a view of one of the printing rolls with the wheel on the
end. Those rolls are made of wood of any diameter, with a center of iron quite
through 'em; on these rolls are cut or engraved patterns of any kind. The.
printing rolls run in steps of any kind; those steps are fixed on the semicircular
pieces of wood or iron E, E, E. The colour rolls are made of wood, but
hollow in the middle, with iron centers through 'em, and may be of any size..
Those rolls are covered with three, four, or more foll'ds of strong wollen cloth,
or other soft substance; over that is put a piece of oil cloth, parchment, or
other substance that will not permit water to pass through it; over that is put
one or two folds of strong wollen or other cloth, and over that one piece of finer
woolen cloth; on this the colour is put by means of brushes, or troughs may
be fixed above 'em with openings so as to let the colour come out on to the
colour rolls. If the colour does not cover the rolls evenly it may be teas'd with
brushes. Motion may be given to the machine by fixing the moving power to
the roll B, B, B, or any of the printing rolls, but it is easiest moved by pulling
at the printed cloth, as represented in Figure 1st, or by the roll. B, B, B.
The machine will print one, two, three, or more colours without any wheels
on the ends of the printing rolls, but not with so much certainty of putting
the colours in their proper places, unless in stripe patterns.
