PROVISIONAL SPECIFICATION.
Improvements in Presses for Copying, Printing, Packing, Stamping,
Moulding, and the like.
I, JETHRO MARSH, of 4 Wellclose Square, in the parish of St. George in the East,
and County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
.
This specification refers to improvements in a press the patent for which has already
heen granted to me :-No. 13,401, dated Oct. 4th 1887,-which consist in substituting
for the compression link a vee shaped link, and for the cross peice of the forked
lever, a tension rod. The vee link together with the tension rod form a truss similar
to that of a roof, but inverted. The pressure is transmitted from the upper ends of
the legs of the forked lever down the legs of the vee link to the apex, which may
bear directly upon the platen, or be furnished with an adjusting screw, to allow for
variation in the thickness of copy books, etc.
The legs of the vee link are prevented from spreading by the tension rod which
passes through the ends of both, and is screwed or otherwise fastened to the upper
ends of the legs of the forked lever. A bandle may be formed of, or upon the tension
rod, by which to pull the forked lever up and forward, or the logs of the forked lever
may be produced beyond the point where they are attached to the tension rod, the
handle being made of, or upon another rod parallel to the tension rod, its ends
fastened to the upper ends of the produced ends of the forked lever, at any distance
from it.
In the press adapted for portability, I disconnect the vee link where it is jointed
to the platen, so as to allow the latter to lie flat upon the bed, and the vee link to lie
flat upon the platen. The press can then be contained in less space, for packing.
I may however, disconnect the vee link from the legs of the forked lever, or the latter
from the bed to obtain the same result. I also make the produced ends of the legs
of the forked lever separate from the main legs, jointing them where they are attached
to the tension rod, so that they will vibrate about the latter. To prevent the produced
ends being pulled over too far, they are provided with stops, or by catches which
pass through the bosses of the lower parts of the produced ends and engage in gaps
either in the upper ends of the vee link, or legs of the forked lever.
Instead of a vee link, I may have two straight compression links, one upon each
side of the platen, their upper ends connected to the upper ends of the legs of the
forked lever, a tension rod running through both of them, its ends being fastened
into the ends of the legs of the forked lever, and a handle formed of or upon it, as
described for the vee link. The lower ends of the compression links are connected to
the platen, one on each side.
In this case, either the ends of the legs of the forked lever, or the ends of the
links may be produced beyond the tension rod to carry the bandle, or as before
described they may be made separate for portability. In this case again, I may dis-
connect the compression links at either end, or the legs of the forked lever from the
bed.

Improvements in Presses for Copying, Printing, Packing, Stamping,
Moulding, and the like.
I, JETHRO MARSH, of 4 Wellclose Square, in the Parish of St. George in the East,
County of Middlesex, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
'tained in and by the following statement :-
This specification relates to improvements in a press, the patent for which has
already been granted to me :-No. 13,40187.
Referring to the accompanying drawings in which like symbols denote like parts:
I substitute for the compression link described in the former specification, a com-
pression link, B, which is preferably V shaped, as shown in figs. 1, 2, 3, 4, 5, 6, 7
and 10, and for the cross peice of the forked lever, a tension rod, a, this rod, b,
together with the links formerly styled the "legs of the forked lever," form a
U shaped lever, A.
The pressure is transmitted from the shoulders of the lever, A, down the legs of
the link, B, to the apex, which may bear directly upon the platen, C, or upon a pin
in the platen, as shown in figs. 3, 4 & 7, or directly upon the bed or upon a pin in
the bed, or it may be furnished with an adjusting screw, S, to allow for variations in
thickness of the matter to be pressed, this screw is attached to the platen, C, in such.
a manner that it may be turned in its joint preferably I use a ball and socket
joint, v, figs. 1 & 2 or I may use a loose peice, 7, fig. 6. At its opposite end the
screw is furnished with a head, y, suitable for turning with the fingers. In another
arrangenient the screw does not turn, but is set in the required position by means of
the nuts, z,, figs. 10 & 11, those nuts may be made to be turned by hand instead of
by spanner, as shown.
The legs of the link, B, are prevented from spreading by the tension rod, a, which
passes through them, and into, or through the legs of the lever, A, near the shoulders
where they may be screwed or otherwise fastened, a method of fastening is shown
at h, h, fig. 1. A handle, i, may be formed of or upon the tension rod, a, by which to
operate the lever, A, or the legs of the lever, A, may be produced beyond the points
where they are attached to the rod, a, the handle, i, fig. 3, being formed of or upon
another rod parallel to the tension rod, a, or the ends of the link, B, may be produced
beyond the tension rod, a, as shown in fig. 4, the handle being formed of or upon
another rod, j, also parallel to the rod, a.
.
On the ends of the lever, A, are stops, t, fig. 2 and corresponding stops, u, on the
bed, D, or on the platen, C, if the lever, A, be attached to that which prevent the legs
passing much further than perpendicular to the bed when the pressure is applied.
To guide the platen to, or from the bed, I may use either of the devices described
in the former specification, or those shown in figs. 2, 2ª, 5ª, 5, and 6. b, figs. 2 & 2",
is a lug having in it a slot, c', through which passes the pin or screw, d¹, being
fastened into the ears, e¹, e¹, of the platen, C. a spring, f, may be placed in the
recess, g¹, to raise the pin, d, and platen, C. In figs. 5 5 & 6, a pin, h', or
pins, h¹, h, in a bracket, ¹, or brackets,,, on the bed or platen work in slots in
corresponding brackets on the platen or bed.
B³,
Instead of having a V shaped compression link, I may have two links, B,
figs. 9 & 12, in fig. 12,-for printing the length of the lever, A³, is adjustable by
means of set nuts, s', s¹, s¹, s². The lever, A, is attached to the platen instead of to 4
the bed as in fig. 9.
In the press adapted for portability, I form the joint at the apex of the link, B. so
that it may be quickly and easily disconnected from the platen, one arrangement is
shown in figs. 5 & 6. The screw, S, terminates in a stud, k, of smaller diameter than
the screw, S, this stud passes through a loose peice, l, having projections, m, m, upon
each side, which engage with the hooked bearing, n, on the platen, C, and from which
it does not escape, because the movement of the pins, m, m, is never toward the open
part of the hooked bearing, n, the loose piece, 1, being rectangular in plan—figs. 5 & 6,

page_text: cannot turn in the slot o, but the stud, k, is free to turn in the piece, l, from which it
cannot part because of the nut, p. Instead of the stud, k, a screw may be used,
passing through the hole formed in the loose piece, 1, and entering a screwed hole in
the end of the screw, S. Another way of making the screw to easily disconnect from
the platen is shown in fig. 6*, the end of the screw, S, is ball shaped and fits into a
socket q' in which it may turn, but from which it cannot escape except when purposely
disengaged by pushing the ball of the screw in the direction of the arrow. To obtain
the same result, 1 may make the ends of the lever, A, hook shaped, so that they may
be disconnected from the pins p', p'. In this press the handle, i, may be formed of or
upon a rod carried by links, 9, 9, which are jointed to the tension rod, a, at the ends
opposite to the handle, the ends of the links, q, q, at the joint, are provided with
stops, r, and there are corresponding stops, s, on the ends of the link, B, or at the
shoulders of the lever, A, which prevent the links making other than a previously
determined angle or line with the legs of the link, B, or legs of the lever, A, whon
the pressure is applied, the disconnecting screw, S, and links, q, q, allow the
press to be folded up for packing into a small space. The guide, G, in this case is
made so that neither of the brackets stand above the level of the top of the platen
when the press is closed.
Another form figs. 7 & 8, is shown as a lemon or other fruit press, in which the legs
of the lever, A, are produced beyond the tension rod, a, and bent inward, meeting in
a handle, j, or the legs of the link, B, may be produced beyond the rod, a, to meet in
the handle,. The platen, C, and bed, D, are of form suitable for the work, the
compression link in this case is formed of the legs, B, B, with a pin, k¹, joining them
upon each side of the rib, 1, on the platen, C, the dotted lines show another method
of making the link, B.
This press may be furnished with an adjusting screw as in figs. 1 & 10, such a press
might be used to advantage in pressing or moulding soap and other yielding
substances.
For pressing cooked vegetables, etc., the forms of levers, A, and links B shown in
figs. 3, 4, 7 & 9, would be particularly suitable.
For printing purposes, where a self inking arrangement is used, the press may be
made as shown in fig. 10. The compression link, B, is jointed to the bed at, t, and
the legs of the lever, A, are jointed to opposite sides of the platen, C, at u, u The
press described in the specification No. 13,4017 is shown at fig. 11, arranged in this
manner with a compression link, B¹, adjusted in a similar manner to link, B, fig. 10.
As the method of operating these presses is precisely similar to that fully
described in the former specification, I do not consider it necessary to repeat it here."
I do not limit myself to the proportions shown in the drawings, for instance, the
difference between the centre of the joint of the link, B, or links B2, B3, with the
platen, C, or bed, D, and the centres of the joint of the lever A, with the bed, D, or
platen, C, may be increased or diminished as circumstances require.

tion, and in what manner the same is to be performed, I declare that what I
