Apparatus for Stencil Printing on Oards.
I, FREDERICK ELLAM, of 12, King Street, Cheapside, in the City of London,
Copying Apparatus Maker, 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 invention relates to apparatus for stencil printing a number of cards
successively brought under a stencil plate or sheet through the pervious parts of
which ink is pressed by a roller on the card below:-
The accompanying drawings shew a machine according to this invention. Figs. 1
and 2 are side views showing the moving parts in two different positions, Fig. 3
is a plan, and Fig. 4 is a longitudinal section, Fig. 5 is a part transverse section
shewing the side guides for the cards.
By means of a winch handle A or other power a crank shaft B is caused to
revolve in the direction of the arrow. The crank is linked by a connecting rod C to
a feed slide block D which is guided on rods d as it is caused to reciprocate under
a box E containing a number of superposed cards loaded by a weight F. On the
slide block D there is fixed adjustable in height a strip of metal e the front end
of which, as the block D reciprocates meets the rear edge of the lowest card in the
box and pushes it forwards, each card as it is thus advanced pushing forward those
in front of it, which are guided along a table F by metal strips f which are fixed
at the sides of the table and overlap the side edges of the cards. The feed block D
is connected by links D' to the axis of a roller G which receives ink from another
roller g that is inked by hand and can be raised out of the way of G when there is
sufficient ink on G. The axis of the roller G reciprocates in the slots of side
frames I which are pivotted at I and are pressed down by adjustable springs such
as . The front parts h of the frames H rest on cams K on the crank shaft, these
cams, as the shaft revolves causing the frames to ascend and allowing it to descend.
On the frames H is laid a frame L holding the stencil plate or sheet, this frame
having at its sides hooks which overlap with certain clearance ledges of the
frames H which are adjustable in height, so that as the frames H rise they raise
the stencil frame L with them, but when they descend, they leave the stencil frame
resting on the sides of the table F.
.
The apparatus works as follows; —
-
While the feed block D is advancing a card, the frames H and stencil L are in
their raised position due to the action of the cam K. but the stencil is not raised so
far as the frames and the inking roller G which advances without delivering ink
on the stencil. During the return stroke of the feed block D which is effected
without moving any card, the frames H and inking roller G are in their lowered
position as allowed by the cams K and depressed by the springs so that the
roller G travels back bearing on the stencil and pressing ink through its pervious
parts on the card below it. This action is repeated for every revolution of the
crankshaft.

invention and in what manner the same is to be performed, I declare that what
I claim is:
Apparatus for stencil printing on cards, constructed and operating substantially
as described with reference to the drawings.
