Claims. (Cl. 234-128)
This invention relates toy a high speed card punch for 10
use in making cards for business machines such `as sorters
simpler and more reliable card punching device which
can be operated at high speeds ythan those in present
use today or those which have attempted to obtain simi
lar results.
Other objects of the invention Will be pointed out in
the following description and claims and illustrated in
the «accompanying drawing, which discloses, by way of
exam-ple, the principle ofthe invention and the best mode,
which has been contemplated, of applying that principle.
In the drawing, a cross-sectional View is shown of the
principle of the invention.
Referring to the drawing, cards are shown at 10 which
are adapted to be fed by a plurality of pairs of feed rolls

Therefore, a worm-like motion is provided to the card
since the card is stationary at the punch station when
the amount of card being fed by the feed rolls 12 is
conforming from the position 54 to that at 56, and the
amount of card being fed away from the punch station
by the rolls 13 is conforming from the position at 55
to that at 57.
If the card does not readily assume the position at 56
from that at 54, when the leading edge of the card first
leaves the feed rolls 12, a complementary cam 58 may be
used for this purpose. Also, if the card has a tendency
to move while at the punch station during the interval
that the card is changing card paths, a brake means
of the card as it passes the punch station so that the
intermediate portions assume the different desired posi
tions, other guide means or braking means can be used
at the punch station.
In order to simultaneously punch more than one
column in series or parallel, a plurality of card punching
and feeding devices may be disposed adjacently on a single
machine for this purpose.
While there have been shown and described and pointed
out the fundamental novel features of the invention as
applied to a preferred embodiment, it will be understood
that various omissions and substitutions and changes in
the form and details of the device illustrated and in its
operation may be made by those skilled in the art, without
