I, JOHN LEWTHWAITE, of Woburn Place, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR DATING OR MARKING RAILWAY AND OTHER TICKETS, CARDS,
INVOICES, BILLS OF LADING, AND DOCUMENTS," to be as follows:-
My Invention relates to an improved construction of apparatus for
dating or marking railway and other similar tickets, cards, invoices, bills
of lading, or documents whereby a perfect inking action is secured
by means of an inking roller, and a vibrating ink distributor, together
with arrangements for ensuring a perfect impression from any ordinary
printer's or machine inks.
The Invention consists in a mechanism contained in a square, oblong,
or other shaped box or frame to carry the requisite bearings, and which
is conveniently arranged so that any of the parts may be easily removed.
The sides of the box carry transverse pins which support rocking frames,
arranged with teeth or other appliance, so that the movement of one
frame is communicated direct to the other. One of the frames, the upper

page_text: one, is arranged to receive the types or marking stamps which project
beyond the lower face, the stamps being held in position by a screw plate
or some similar contrivance. The lower frame carries the ink distributing
roller which receives an intermittent movement at each back stroke to
bring fresh parts of it into action to distribute the ink equally. This roller
also gets a lateral movement by a pin bearing against a cam on its end,
the required pressure being obtained by means of a coiled spring. The
lower frame has another frame pinned to it in such manner that it drives
the elastic inking roller which is attached to it upon and beyond the
types before coming in contact with the lower frame carrying the dis-
tributing roller, while it afterwards by the same pushing or inward
motion forces the elastic roller into contact with the back distributing
roller which in its turn is also forced by the same inward motion
against a stop or catch acting upon a catch wheel attached to this roller,
and by this means the ink is variably spread at every pushing or printing
of a date or other mark. This additional frame forms the front of the
lower part of the apparatus and has the mouth piece into which the
tickets are inserted, and the pad for receiving the pressure after each
push from the types or stamps. The rocking frames, top and bottom, are
returned to position by a coiled spring or other suitable means. The
front plate finds its level with the face of the box by means of a spring
on its back or otherwise acting upon the edge or against some other part
of the lower frame. The elastic inking roller has a frame of its own,
which can be easily detached by undoing a thumbscrew. The distance
of travel of the frames is governed by adjustable or fixed stops. The push
in action of the front plate and mouth piece causes it to turn upon its
pin and rise to bring the elastic inking roller into such contact with the
types as to ensure their being properly inked, while at the same time it
enables the said elastic roller to pass clear of the types and impinge upon
the distributing roller in the back or lower frame during the second part
of the pushing motion, which brings the catch wheel of the said dis-
tributing roller under the action of the catch fixed upon the side for the
purpose of giving it a motion equal to a part turn round, whereby both
rollers being in contact under that operation a constant change of inking
surface is secured.
