A communication from JOHN ROBERT CARTER, of the City of Toronto,
Canada, Manufacturer.
I ALFRED JULIUS BOULT of 323 High Holborn, in the 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 ascertained in and by the following
statement
The object of the invention is to devise mechanism by which numerals or other
signs may be printed on paper on both sides during the passage of the web or sheet of
paper through the machine; and it consists, essentially, of two sets of stationery
platens having their faces in substantially the same plane and facing in opposite
directions, two sets of intermittently-changing printing types provided with mechanism
by which the two sets of types shall derive a reciprocating action so as to bring each
set of type against its respective platen, substantially in the manner hereinafter
more particularly explained.
Figure 1, is a perspective view, showing the principal parts of the mechanism
involved in this invention.
Figure 2, is a perspective detail of one of the stationary platens.
Figure 3, is a detail of the inking rollers.
Figure 4, is an enlarged detail, showing the mechanism for operating the type and
inking rollers.
Figure 5, is a sectional elevation of the machine.
A, represents a roll of paper from which the paper to to be printed and numbered
is drawn. I show this roll in Figure only, on reference to which figure it will be
seen that the paper first passes over the printing platen, B, then between the platens, C,
between the feeding rollers, D, and then between the knives, E, which cut off the
paper the required length, but as they are not involved in this present invention it is
not necessary to describe them in this specification.
F, is the main driving pinion, which derives motion from any convenient source,
and from which all the rest of the mechanism in the machine is driven. This
pinion, F, meshes with the spur wheel, G, upon which the crank pin, a is fixed.
H is a pitman connected at one end to the crank pin, a, and at its other end to a
pin on the press-head W.
A pitma, I, connects the press-head, W, to the coupling link, J, which is pivotted
upon and connects the two bars, K, loosely journalled at their other ends upon the
spindles L and M. The coupling-link, J, is provided with a suitable guide-piece, b,
which fits into the horizontal slot, c, made in the frame, M. The spindles, L, and M,
are carried in suitable bearing-boxes, d, fitted into vertical slots, e, made in the frame N
as shown.
I am only referring to the mechanism on one side of the machine, but it will be
understood, as indicated by Figure 1, that the mechanism herein referred to is
duplicated by the opposite side of the machine.

page_text: O, and P, are two rollers fixed, respectively, to the spindle L and M.
The surface of the platen, G, opposite to the type roller, O, is on the same plane as
the surface of the platen, C, opposite to the type roller, P, so that the entire surface of
the paper, A, passing between the said platens, as indicated in Figure 5, is on the
same plane.
Q, is a composition roller for inking the type on the roller, O, and R, is a roller for
inking the type on the roller, P. Each of these inking rollers, Q, and R, is provided
with a suitable ink-distributing roller, f, which derives motion from contact with their
respective inking roller.
S, are metal inking rollers, each revolving in its respective ink font, as indicated,
and held in contact with their respective inking roller, Q, or R. An arm, g, is loosely
journalled on the spindle of the upper inking roller, S. This arm is connected to the
coupling-link, J, by the rod, h, and to the arm, i, loosely journalled on the spindle of
the lower roller, S, by the rod j. On each of these arms, g, and i, a dog, k, is pivotted
and arranged to engage with the ratchet teeth of its respective ratchet-wheel, 1,
fastened respectively to the spindles of the inking rollers, Q, and R.
m, are ratchet dogs pivotted on the coupling link, J, and arranged to engage with
the teeth of the spur-wheels, T, which are secured one to each of the spindles L, and M.
From this general description, and the construction of the parts specified, it will be
understood that when the driving pinion, F, revolves and the paper is drawn from the
roll, A, by the action of the feed rollers, D, which are not necessary to describe
here, the paper will be acted upon by the printer, B, and simultaneously with this
the coupling-link, J, will be pushed in its horizontal slot, c, so as to bring the type
rollers, O, and P, against the paper on their respective platens, C, and while the
coupling link, J, is thus moving it pushes the rod, h, so as to move the arm, g, and
through it and the rod, j, the dog, k, sufficiently far to enable them to grasp a tooth in
their respective ratchet wheels 7. The dogs, m, are at the same time moved so as
to engage with another tooth in their respective spur-wheels, T.
As the driving pinion, F, continues to revolve the coupling-link, J, is brought back
into its initial position, and in thus moving, the inking rollers, S, and spur-wheels, T,
are caused to revolve by the action of their respective ratchet dogs, and as the type
rollers, O, and P are connected to the same spindles as the spur-wheels, I, they will
likewise revolve so as to bring a fresh number opposite to their respective platen.
It will be understood that the inking-rollers herein referred to are caused to revolve,
and the distributing roller will also revolve, so long as the driving pinion, F,
is in
motion.
In order to impart a reciprocating longitudinal motion to the distributing rollers, f,
I attach on the spindle of the rollers, Q, and R., cam U. (See Figure 3.) These cams
are shaped substantially as shown, so that as the rollers, Q and R, revolve, their
respectivo distributing rollers,, are moved longitudinally by the action of the said
cams, as will be understood on reference to Figure 3 referred to.
It will be noticed that the platens, C, are, as indicated by Figure 2, adjustably
connected to the bars, V, so that they may be readily moved across the machine so as
to bring them opposite to their respective rollers, O, and P, which, I may mention,
are likewise adjustably connected to their spindles. This enables the numbers to be
imprinted in any desired position on the paper.
It will also be noticed that I pivot on the frame, N, of the machine the dogs, n,
designed to engage with the spur-wheels, T, so as to prevent the said spur-wheels from
revolving backwards during the time that the dogs, m, are being adjusted for the
purpose of engaging with fresh teeth.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my foreign
correspondent I declare that what I claim is :-
1. Two sets of stationary platens having their faces in substantially the same plane
and facing in opposite directions, two sets of intermittently changing printing types,
in combination with mechanism arranged to impart a reciprocating action to the two

page_text: sets of type so as to bring each set of type against its respective platen, substantially as
and for the purpose hereinbefore described.
2. The pitman, I, connected at one end to the pivotted printing head which derives
a rocking movement through the pitman, H, from the revolving spur-wheel, G, and
at its other end to the coupling-link, J, in combination with the bars, K, arranged to
connect the spindles, L, and M, to the coupling link, J, substantially as and for the
purpose specified.
3. The coupling-link, J, provided with guide pieces, 7, which fit into their respective
slots, c, made in the frame N, the bars, K, connecting the spindles, L, and M, to the
coupling-link J, in combination with the bearing-boxes, d, supporting the spindle, L,
and M, and fitting into the vertical slots, e, arranged substantially as and for the purpose
specified.
4. The dogs, m, pivotted on the coupling-link, J, and arranged to engage with the
spur-wheels, T, as specified in combination with the rod, h, connected at one end to
the coupling link, J, and at its other end to the arm, i, which is loosely journalled upon
the spindle of the upper roller, S, the dog, k, pivotted on the arm, g, and arranged to
engage with the ratchet wheel, 1, secured to the spindle of the said roller, S.
5. The dogs, m, pivotted on the coupling link, J, and arranged to engage with the
spur-wheels, T, as specified, the rod, h, connected at one end to the coupling-link, J,
and at its other end to the arm, i, which is loosely journalled upon the spindle of the
upper roller, S, the dog, k, pivotted on the arm, y, and arranged to engage with the
ratchet wheel,, secured to the spindle of the said roller, S, in combination with
the rod connected at its upper end to the arm, g, and at its lower end to the arm, i,
which is loosely journalled on the spindle of the lower roller, S, and has a dog, k,
pivotted on it and arranged to engage with the ratchet wheel, 7, secured to the spindle
of the lower roller, S, substantially as and for the purpose specified.
6. The platens, C, adjustably connected upon bars secured to the frame of the
machine so that the faces of the platens shall face in the opposite direction but will be
in substantially the same plane, in combination with the type rollers, O, and P,
adjustably connected to their spindles shall derive a reciprocating action so as to bring
the face of the type roller simultaneously against their respective platens.
