Year: 1809

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BROWN, of Mile End New Town, in the County of Middlesex, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-eighth day of
November, in the fiftieth year of His reign, give & grant unto me, the said
John Brown, my exors, adññiors, and assigns, His especial licence, full power,
sole privilege and authority, that I, the said John Browne, my exors, admors,
and assigns, during term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN NEW IMPROVEMENTS IN
A MACHINE OR PRESS FOR LETTER-PRESS PRINTING, & ALSO FOR PRINTING
VARIOUS ORNAMENTS AND FIGURES, PART OP WHICH IMPROVEMENTS MAY DE
APPLIED TO PRESSES NOW IN USE;" in which Letters Patent there is contained
a proviso, obliging me, the said John Brown, by an instrument in writing under
my hand and seal, to cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled
in His Majesty's High Court of Chancery within two calendar months after
the date of the said recited Letters Patent, as in and by the same (relation
being thereunto had) may more fully and at largo appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Brown, do hereby declare that my said Invention is particularly de-
scribed and ascertained in the Drawings hereunto annexed and the following
description, that is to say:--
Figure 1 is a machine or press made of cast iron, wood, or any fit material.
Figure 2 is a bed made of cast iron, wood, stone, &c., which must be faced
true, for the types to lay on. Figure 3 is two square or round pieces of cast
iron or wood, or any other fit material, which must be fixed through two
square or round holes, to guide them true, and fixed to Figure 2, to press
upwards, that the bed shall, not slide one way nor the other. The power is
given by levers being fixed to a round roller, spindle, or cylinder, as Figure 4,
to move on its own axis by motion of the roller, Figure 5, where the handle is
fixed on, to give the motion to the lever, Figure 6, which, by winding or keeling
round the rigges or sheath fix't to roller, Figure 5, the chain, strap, or rope
passing round the center of the roller, give a considerable additional power to
the pressure. Figure 7 is a carriage with 4 wheels, with lebeled grooves to
run on the top of the frame backwards and forwards to Figure 9, which is
connected with Figure 8. The bottom part of Figure 7 is the upper bed,
which slides under 4 strong pieces of iron fixed to the frame on each side, for
the bed, Figure 2, to give its pressure against. Figure 8 is a roller with
sheath; on that the cord or strap connected with Figure 9 run round, to throw
the carriage in and out, by means of a lever and cog or toolt wheel. The
workmen pulling down the lever, brings the carriage from Figure 9 over tho
bed, Figure 2, and the workmen let go the lever; the weight at Figure 9
brings back the carriage. There is another way of giving the presser upwards,
by a screw being fixed to the middle of the bed, Figure 2. There must be a
guide through two square or round holes, and in the middle part of the scrow
a lever to be fixed fast, and a strap, chain, or rope to be fixed to the end of
the lever, and an upright spindle or shaft to be fixed outside the frame,
with a beveled wheel and pinion on the top, with a handle to give motion to
the lever by fixing a chain, rope, or strap to the middle part of the spindle or
shaft, and to have a rigger or sheath of wood or iron on the middle part of the
upright spindle, the chain, strap, or rope winding or keeling round, to give
motion to the lever when it has revolved round the rigger or sheath;
it laps round the small center of the spindle, and gives a considerable
additional power. Another way of pressure, by a roller being fixed on the
bottom part of the carriage, where the upper bed, Figure 7, is, and by
the same motion roles oves the tympan and types, and gives the impression.
There must two square pieces of iron or wood placed on each side the bed, to

page_text: lay the same height as the types, to bear up the rollers, so as they clear the
top part of the types. The tympan must drop in four grooves or holes at each
corner, to keep it steady, so that the roller does not shake the tympan. Thero
is little difference in this tympan from the usal tympans. The part which the
upper bed or roller comes must have a plate of sheet brass, copper, or iron, or
wood, fixed fast to the frame of the tympan, the roller passes over, and gives
the pressure on the types. I apply two tympans, one on each side, so that two
workmen may use the same form, or print from the same copy, and by this mode
are enabled to do nearly double the work in the same time; for one may
give the impression while the other is getting another sheet on the other.
tympan, and the rollers, Figures 15 and 16, being lifted up by the workman,
and falls on the types, gives them a sufficient quantity of ink and weight.
Figure 17 brings the feeder back to Figure 14. Figure 11 is the frame which
the ink roller is fixed, and to have a true edge of brass, steel, iron, wood, &c.,
as a scraper, to be placed on the side of the roller, to bring the ink off smooth
and even; and the roller to be of brass, pewter brass, or any other kind of
mettle, made hollow inside, so as to contain a quantity of hot water or steam, to
keep the ink of a proper thickness. That it may distribute better, it is sup-
ported by a small roller underneath the frame. Figure 12 is a foot-board
connected to the frame, Figure 11. When rollers, Figure 13, want ink, the
workman may put his foot on the board, Figure 12, and it rises the ink roller
up to Figure 13, and gives as much ink as may be wanted. Figures 13 and
14 are the receiving rollers, which are connected by two pieces of woollen
cloth or cotton, or other cloth or leather skins of various sorts, or any fit
material, in the manner of a jack towel, sewed round them. Figure 15 is two
rollers, same as 13 and 14, but cover'd with a more elastic and softer substance,
to have a soft blanket sewed round, same as Figures 13 and 14, and on the
outside a skin or skins of leather, tanned or untanned, superfine cloth, cotton, or
oil cloth, or any other fit material, may be used to the top feeding rollers,
which receives the ink from Figures 13 and 14; in side the upper rollers,
between the the blanket there is a board similar to box without cover, fixed
inside the blanket, for a bed of wool to lay on, and at the end, Figure 16, is con-
nected a roller which must be weighted on each side by rope or strap, Figures
17 and 18, so that the workman may with ease lift up the top feeding rollers,
Figures 15 and 16, which will fall on the types, Figure 2, and give the
a sufficient quantity of ink; or the types may be supplied with ink by rolling a
roller over them, and by the weight, Figure 17, revolves back to Figure 14,
which is always in motion, by means of a jack, Figure 19, to work either by
weight or spring. The rollers, Figures 13, 14, 15, may cogs both on the jack

page_text: towels, and also on the rollers, as a guide to keep them in their proper places,
and the roller, Figure 16, to have a streight groove out the length of the roller,
that the two feeding rollers 15 may slide each way, as may be wanted.
In witness whereof, I, the said John Brown, have set my hand and
seal, this Twenty-seventh day of January, in the year of our Lord!
One thousand eight hundred and ten.
