IMPROVEMENTS IN PRINTING PAPER-HANGINGS
Year: 1837

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
PALMER, of Sutton Street, Clerkenwell, in the County of Middlesex, Manu-
facturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-ninth day of July, in the first year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said William
Palmer, Her especial license, full power, sole privilege and authority, that I,
the said William Palmer, my exors, admors, and assigns, or such others as
I, the said William Palmer, my exors, adfiiors, or assigns, should at any time
àgree with, and no others, from time to time and at all times during the term
of. years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN PRINTING PAPER-HANGINGS;" in which
said Letters Patent is contained a proviso, that I, the said William Palmer,
shall 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 Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Palmer, do hereby declare the nature of my Invention, and the
manner in which the same is to be performed, are fully described and

page_text: ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed and to the figures and letters marked thereon
(that is to say) :-
My Invention consists in a mode of combining certain mechanical instru-
ments or apparatus into a machine for printing paper-hangings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is the left-hand side view of a machine arranged and combined
according to my Invention; Figure 2 is a plan, and Figures 3 and 4 are front
and back views of the machine. In each of these Figures the same letters
indicate similar parts; a, a, being the framing of the machine, the construction
of which is clearly shewn in the Drawings, and although the same is of wood,
it is evident that it may be of iron; b, b, is the block or surface to be printed
from, which is affixed by set screws c, c, in the frame d; this frame is sus-
pended from and moves on the axis e, as is clearly shewn in the Drawing,
such axis e being affixed to the arm f, which arm is attached to the hollow
axis
9, which moves in bearings h, h, and to this hollow axis g, g, are
affixed the handles i, j, the handle j being a curved plate within which the
handle can lie, and when the handles j, k, come together, they act as one
lever handle, as hereafter explained. The handle k is affixed on the axis 1,
which is within the hollow axis g; the object of the handle and the axis / is
to give suitable pressure to the block or surface when printing, which it does
in the following manner:-m is a crank affixed on the other end of the axis
to that at which the handle k is affixed, as is shewn in the Drawing; n is a
connecting rod (capable of adjustment, as is also the crank m) which connects
the crank m and the lever o, which moves on the axis o', there being a crank
or arm o², which is connected to the pressing lever p, by a pin joint; q is a
weight which has constantly a tendency to lift the lever o; and p' is a spring,
which constantly draws the pressing lever from the printing block when
released therefrom, all which will readily be traced in the various Figures of the
Drawing; is a balance weight connected to the arm f, by which means the
printing block and other apparatus connected therewith is constantly in a state
of balance, and hence the block requires but little power in transferring it to
and from the surface where it obtains color and to and from the paper where
the impression is given; s, s, is a frame, which may be called the parallel frame,
as it, (together with the cords) hereafter mentioned, keeps the printing block
constantly parallel with the surface where it receives color and with the paper
where it gives off its impressions; this frame s, s, moves on axes in bearings
ats, s; the arin and the frame s, s, are kept equidistant and parallel

page_text: with each other by the rod t, and this rod also aids to lift the frames, s,
when the impression has been given. v is an arm affixed to the hollow
axis g, and w is an arm attached to the frames, the arms v and w being
connected by means of the connecting rod x, as is clearly shewn in the:
Drawing, and will readily be traced therein, and enables the axis g to move.
the block or printing surface from the color surface. y is an endless cloth of
fustian, which moves on rollers y', y, that of y¹ having at one end a number.
of raised projections or handles by which the boy can conveniently turn.the
roller to advance the paper to be printed; is roll of paper to be printed, .it is:
placed in a trough in front of the machine; A, A are register points, which
are capable of being set on the bars B, in order that the patterns painted by
the block or surface may be accurately joined; C is a table, the surface of
which is covered by three or more layers of flannel, in order to obtain a
suitably elastic surface (or other means may be resorted to for that purpose),
on this elastic table the color blanket is laid; D is the impression table over
which the endless cloth passes; this table is also covered with one or more
layers of flannel to give the surface an elasticity.
Having thus explained the nature of the parts, I will shortly explain the
mode of working. A boy stands at the point E, and by a brush lays on color
to the color surface C; another boy stands at the point F, to work the handle
i, j, k, and a third boy stands at the point G, and by the roller y¹ and the
endless. cloth moves the paper forward till it be brought correctly to the
register points; the machine would be at this moment in the position shewn
at Figure 3, that is, the block is on the color surface C. The boy at F
moves the handles i, j, till the handle j and the handle k come together, he
will continue the movement, by which means the block or printing surface will
be raised off from the color surface C, and brought on to the paper to give its
impression, and so soon as it arrives on the paper, the boy at G moves the
pressing lever p inwards till it rests on the axis e, and the boy at E forces the
handle k still further, by which means pressure will be given to the block or
printing surface; the boy at G then pushes off the pressing lever p, and the
boy at E moves back the handles i, j, k, till the block or printing surface is
removed back to the sieve or color surface C, to receive fresh color, and the
boy at G brings forward a further surface of paper to receive the next
impression.
Having thus explained the nature of my Invention, and the manner of
working the same, I would have it understood that I lay no claim to any of
the parts separately nor combined, other than is hereafter particularly pointed
out; and I would remark, that some of the detail of the arrangement may be

page_text: varied, provided the general features of the combination be retained. But
what I claim as my Invention is the mode of combining a flat color surface C
with the combined apparatus for moving and working the block or printing
surface in the process of printing paper-hangings, whereby the block or printing.
surface is alternately brought to the flat color surface and to the paper to be
printed, as above described.. And, secondly, I claim the mode of combining
the axle, the lever k, with the lever o, in order to obtain the requisite pressure
by the pressure lever p to the block or printing surface, whether it be moved
and actuated according to my first improvements, or otherwise, when used for
the process of printing paper-hangings.
In witness whereof, I, the said William Palmer, have hereunto set my:
hand and seal, this Twenty-ninth day of January, in the year of our
Lord One thousand eight hundred and thirty-eight.
