Improvements in Writing and Print Copying Machines.
I, MARTIN WRIGHT, of The Cyltine Manifold Copying Machine Company,
Highfield Works, Leicester, Engineer, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to construct a machine in a novel manner and
with special detail parts in order that fac-simile copies or transfers of writings
and prints can be made in desired quantities from an original.
For the purpose of my invention, I employ gelatine compound material on paper,
or other suitable material which after being moistened can be strained over a
cylinder for receiving the original writing or print.
The machine is composed of two side frames, a cylinder, a pressure drum,
an inking roller and a director, also a loosely mounted frame which can be
temporarily fixed for pressure, or for release as desired of the pressure drum which
it carries.
The features of novelty constituting my invention, are
1. Appliances by which the gelatinized paper can be secured on the cylinder.
2. A double yet connected toothed wheel on the spindle of cylinder.
3. A stop for limiting the travel of the cylinder for perfecting each impression.
4. Side motioned frame for dropping drum from contact with cylinder.
5. Appliances for operating gripper for taking paper for printing.
6. Appliances for releasing paper when printed.

COMPLETE SPECIFICATION.
Improvements in Writing and Print Copying Machines.
I, MARTIN WRIGHT, of The Cyltine Manifold Copying Machine Company,
Highfield Works, Leicester, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
The object of this invention, is to construct a machine in a novel manner and
with special detail parts in order that fac-simile copies or transfers of writings
and prints can be made in desired quantities from an original.
For the purpose of my invention, I employ gelatine compound material on
paper, or other suitable material, which after being moistened can be strained
over a cylinder for receiving the original writing or print.
The machine is composed of two side frames, a cylinder, a pressure drum,
in inking roller, and a ductor, also a loosely mounted frame which can be
emporarily fixed for pressure, or for release, as desired, of the pressure drum
which it carries.
My invention will be clearly understood by the annexed drawings.
Figure 1 is a plan of the machine complete.

I, gear wheel on axle of pressure drum.

M, gripper pivotted to pressure drum and operated by cam L.
N, post in recess of cylinder C.
P, P, clips for securing gelatinized paper around cylinder C.
Q, double ended screw for coupling clips P, P, and for tightening them up for
stretching gelatinized paper on cylinder C.
R, lever for operating frame E and pressure drum D.
S, front plate.
T, angled slot in plate S.
U, crossed band for operating inking roller F from cylinder C.
V, table or laying on board.
The method of fixing the gelatinized paper on the cylinder and the operation
of the machine for printing fac-similes, copies of writings or prints are as
follows:-
The gelatinized paper being cut to a given length, has its two ends inserted
between the folding leaves of the grippers P, P, and these are kept in close
contact by dogs a, a, which are forcibly slid over one end of each clip to about
the centre.
The gelatinized paper is then damped, and after a little time, the eye b of one
dog is looped on to the post N and the gelatinized paper wrapped round the
cylinder C to bring the other dog and clip into the recess, the ends of the double
screwed pin Q are then inserted into the ears c, c, of the two dogs a, a, and turned
to draw the two dogs and clips towards each other to stretch the gelatinized paper
into close contact and level upon the cylinder.
The original writing or print is now passed through between the cylinder C and
pressure drum D for transferring the imprint on to the gelatinized surface, the
pressure drum is then lowered by a lift of the lever R to move it clear of the
drum C.
The inking roller F is dropped into the slots d (one in each side frame) and
then the ink feeding roller G, several turns of which will sufficiently coat the
roller F with ink for the printing.
The roller F is now lifted up the reverse slot e which permits the roller G to
slide to the bottom of slot d and the squares of its axle to lodge in corresponding
grooves to serve as a support to the roller F which is also pressed into contact
with the gelatinized paper on cylinder C.
The band U is now passed over the pullies f, g, and the cylinder revolved by
the handle on the main wheel H in order to "ink up" the impression on the
gelatinized paper.
The paper to be printed is placed upon the table V and the pressure drum lifted,
the paul of the cylinder C being against the stop J. A sheet of paper is pushed
forward for its edge to enter the mouth of the pressure drum and under the
gripper M, the paul K by pressure on the thumb piece i is removed, and the
wheels H, I rotated, this causes the cylinder C and pressure drum D, which are
of the same diameter to rotate in contact, and simultaneously with the first motion

page_text: the incline of the cam L, which compels the gripper M to seize the sheet
arum D, the tail end j of the gripper bears against and rides
paper for drawing it through the machine.
The gripper retains its hold on the sheet of paper until the tail end arrives
5 the end of the circular faced portion of the cam at 1, when from the action of
slight spring, the gripper is opened, this releases the sheet of paper and allows
to fall on to the bench on which the machine is placed. At this particular part o
the drum's rotation, the paul K comes into contact with the stop J and arrests th
motion of the machine.
1 It is only necessary for obtaining a repetition, or succession of printed copies to
first insert sheet into gripper opening, and then to turn the handle and simul
taneously pressing on thumb picce i to release the paul K from the stop .J.
Any degree of pressure of the drum D against the cylinder C can be obtained
and regulated at will by the adjustment screw n, against which the lever R bears
when said lever is forced down the inclined slot T and under the screw n.
The frame E (with drum D) is pivotted at p in the side franes A, A, of the
machine and the axle ends of the drun D, which are supported by the frame E,
also pass through slotted holes 4, 7, of the side frames A, A, so that when the
drum D is lowered to be clear of the cylinder C, it also moves sideways by the
motion of the lever R when it rides up the incline T, the reverse motion taking
place when the lever is forced down the incline.
The main wheel H has a double set of teeth r, r, each connected by a web s, so
that the lowering of the drum D and of its side motion by the lever R do not take
the wheel I out of gear with the teeth of the drive or main wheel H.
By this arrangement, the cylinder C and drum D are kept in sequence, whether
the drum be up or down.
Instead of the screw Q being threaded at both ends, as above mentioned, it may
have one plain end with shoulder to pass into slot of one ear r, as at Figure 8, and
provided with a square head to enable it to be turned by a swivel key to draw the
clips towards each other to tighten the gelatinized material.
Having now particularly described and ascertained the nature of this inven
ion and in what manner the same is to be performed I declare that what I
laim is :-
1. The machine constructed and arranged as shown in the annexed drawings
or the purpose of printing copies of writings, prints, by transfer by gelatinized
urface, as described.
2. In a machine for printing by transfer from gelatinized surface, the use or
mployment of pivotted gripper on rotating drum D and operated by a cam L
xed on the drum carrying frame E, as described.
3. In a machine for printing by transfer from gelatinized surface, the appliances P,
Q, for gripping and tightening gelatinized material on cylinder, substantially
described.
4. In a machine for printing by transfer from gelatinized surface, a double
othed and connecting web wheel H for retaining the wheel I in gear for both
sitions, to which wheel I can be shifted for pressure or release of dr. m D, as
ecified.
5. In a machine for printing by transfer from a gelatinized surface, so fitting
pressure drum carrying frame that a simultaneous drop and side movement can
imparted to said drum and frame, as and for the purposes specified.
In a machine for printing by transfer from a gelatinized surface, a paul in
n wheel for operation to stop and to free the working thereof, as described
