of the Commissioners of Patents, with his Petition, on the 5th
September 1868.
I, JOSEPH SLOPER, of Walbrook House, Walbrook, in the City of London,
Civil Engineer, do hereby declare the nature of the said Invention for
"IMPROVED MEANS OF AND APPARATUS FOR PERFORATING, PUNCHING, CUTTING, OR
STAMPING CARDBOARD, METAL, AND OTHER MATERIALS, AND ESPECIALLY APPLICABLE
TO PERFORATING RAILWAY TICKETS," to be as follows, that is to say:-
The Invention embraces the constructing apparatus for the purposes
set forth, in which are employed in combination a hanging or vibrating
frame and a forcing rod or plunger carried and guided thereby, and
moving longitudinally with regard thereto, such motion being caused by
one or more cams or inclined surfaces against which the vibration of
the frame causes the rod or plunger to bear; or such motion being
caused by the rod or plunger itself being provided with one or more
cams or inclined surfaces, which by the vibration of the frame are
caused to bear against any convenient resisting surface; in either
alternative a roller or rollers being introduced if desired to lessen the

page_text: friction, or if desired cam-surfaced rollers being introduced into the
combination admitting a quick release from the pressure. It is to be
understood that the motion of the forcing rod or plunger is for pro-
ducing (by proper tools) the perforating, punching, cutting, or stamping
action which may take place against a die or resistance plate or block,
or matrix, or other equivalent carried by the vibrating frame or
otherwise presented to its action.
Also the Invention embraces the making the die or resistance plate, or
block, or matrix to move towards the forcing rod or plunger (during its
action), such motion being derived from the rod itself through lever
arrangements in connection, and the effect being to halve or reduce the
extent of motion of the said rod which would otherwise be necessary, and
so to produce a quick and powerful action.
And I do hereby further declare the means by which the said
Invention is to be carried into effect to be as follows:-The appa-
ratus may have a bed plate or foot supporting a curved pillar or arm,
from top of which the vibrating frame may depend. The said frame
may be made hollow to contain and guide the forcing rod within it, and
an inclined or cam surface may be provided at or near the top of curved
arm near to point of suspension or elsewhere, or the inclined surface
may be made on or carried by the rod at or near to its top or elsewhere,
and their surfaces may be made adjustable; or the friction roller if
used may be "set up "as desired to produce an adjustment. The said
cam action may be provided for motion in one or in both directions, or
the return action may be effected or aided by a spring. The quick
release from pressure of cam action may be effected by making cam on
a roller or wheel with ratchet action; allowing wheel to turn in one
direction only after extreme fulness of cam has been passed. The
forcing rod may carry or act upon the tools (which may be removeable),
and the resistance plate or block may carry or present any corre-
sponding or counter tool to their action; or the relative position of
tools and counter tools may be reversed. And it is to be understood
that the centre on which the frame vibrates may be situate at the top or
bottom or elsewhere on such vibrating frame, and that counterweights
may be employed; and also that if desired the apparatus may be con-
structed in duplicate, one part vibrating from and below an upper
centre, and the other part upwards from and above a lower centre, in
which event the forcing rod or plunger carried by one offers or becomes

page_text: the resistance against which the other acts, and the amount of action
or play of the two forcing rods is halved or divided between them. To
make the resistance plate or block advance towards the rod (during
action) an arrangement may be made somewhat similar to a com-
pensation pendulum, in which the lenthening or depressing of the rod
does by levers raise the weight slung to or carried by them, and the
shortening lowers it or permits it to fall.
