page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
MAUDSLAY, of Margaret Street, Cavendish Square, in the County of Middlesex,
Mechanist, send greeting
WHEREAS Uis most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of His United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-ninth day of
July, in the forty-fifth year of His reign, give and grant unto me, the said
Iemy Maudslay, my exois, adññiors, and assigns, Ilis especial licence, that I,
the said Henry Maudslay, my exois, adinois, and assigns, during the 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 "A PRESS, UPON AN IMPROVED CONSTRUCTION, FOR PRINTING OF
CALICOS AND VARIOUS OTHER ARTICLES," in which said Letters Patent is contained
a proviso, obliging me, the said Henry Maudslay, 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
molled in His Majesty's High Court of Chancery within one calendar month
after the date of the said recited Letters Patent, as I and by the same, rela-
tion being thereunto had, may and will more fully and at large appear

page_text: DESCRIPTION OF THE DRAWINGS.
No 1 & 2 represent an end and front view of the machine, A, A, are
frames of cast 11 on, wood, or other strong materials; B, B, are swinging frames
of ion or wood, the upper surfaces of which are made flat to receive engraved
copper plates, fastened on and regulated by screws at a, a The sciews at b, b,
are to stop and regulate the swinging frames against pieces which project on the
insides of the frames A, A, at d, d; C, are slings or connecting rods of iron or
other metal, which have 1ound holes at D in the bottom end to receive the
ends of the strong bolt D (wluch is connected to the fiame B, B). The upper
part of the connecting rods C, which are forked to pass the pivots of wheels, &c.
on the ends of the frames A, A, and are screwed in the usual way, have two
metal nuts fitted to each to keep down and regulate the cross pieces of 11on
or other metal e, which fit on and into excentiic wheels or cranks E (which alo
made of 11on or other metal), for the purpose of lifting the swinging frame B
by means of the conuccting rods C, C, and pressing the copper plates forcibly
against the unde part of the cylinder or press head F, which is better seen in
No. 3 or 5. Through the excentric wheels, &c. are made square or other
formed holes, which are well fitted on the spindle G, close on the outsides of
insides of the frames A, A, on the outside of which is fitted the toothed wheel
II, which works into and tuins the wheel I, which is twice the diameter of II,
and has on the rim a piece of metal of the proper curve, with three whole
teeth and one half tooth, which in their revolution fall into the teeth of the
wheel K, fixed on the axis of the roller L, which wheel will be regulated as to
its number of teeth by the cucumference of the roller L, which must be twice
or three times the length of the engraving on the plate to be printed fiom. If
twice, it must have eight teeth, if thice times, twelve teeth, or in that propoi-
tion. The half of every fourth tooth must be taken away to let the half tooth
on the segment on 1 pass, that it may stike fanly on the pitch line of the next
tooth. The small roller M, may be used or not as occasion may requic, as it
is only to ease the motion of the blanket which passes over the roller N, which
is to tighten the blanket by means of the screws and sockets O. At the oppo-
site end of the spindle G is well fitted a large wheel P, which is turned by the

page_text: pinion Q on the spindle of the fly-wheel R, and supported by the frame S, of
(11on or wood) This spindle may be turned by hand or any other given
power. The wheel and pinion may be vaned to any power, by altering
the sizes of them in the usual way. The plates may be cleaned in the
usual way by a scraper or
doctor. No 3 is a transverse section section
of the machine, shewing a different mode of using it. The frame A, A,
is the same as in No. 1 & 2, with the addition of two arms or brackets T, T,
which support a frame of iron or wood, on which are fixed one, two, or more
copper plates to print several colours. They move to stops, and are regulated
as in No 1 and 2 The cylinder E is made hollow for the purpose of admitting
stean, which will heat it to any temperature, to day the colour as quick as
printed. The manner of letting in the steam is described in No. 5. The
lifting fiame B acts the same as in No. 1 & 2. No 4 is a lifting frame
which has a cylinder similar to F, and may be used in the place of B, which
makes it a hot press for various purposes, by letting steam into the bottom as
well as the top cylinder, and in case the colour should dry in the plates owing
to the heat, cold water may be made to pass through the cylinder, which will
always keep it cool No 5 is a longitudinal section of the cylinder, excentric
wheels, &c, with the manner of admitting steam by a small pipe at f, which
may be communicated with the boiler of a steam-engine, or a small boiler on
purpose, which will serve one, two, or more presses, each having stop-cocks at
convenient places. 9 is a pipe in the bottom of the cylinder to let out the
condensed water. No. 6 and 7 represent an end and side view of the upper
part of the machine, with the roller L placed above the cylinder, by which
means the blanket is closer, and may, if requned, receive more heat from the
cylinder The roller is moved by the same wheels as in No. 1 and 2, only
differently placed.
