This invention relates to improvements in skip
bars for multiplying punch or like machines, such
as key-pimch .and verifying machines used in the
art of punched-card tabulating.
The skip bar presently used on multiplying

vention.
In carrying out the above object, I may provide
a skip bar whose upper edge is at the “low” level
and is provided with a longitudinal groove of a
length corresponding to the number of columns
on a punch card used in the machine. Three
sets of inserts may be used and adapted for se
lective snug removable reception in said rgroove,
the inserts of each set differing in length, and
the inserts of one set being of a height corre
sponding to “low” level, those of another set being
of a height corresponding to “X” level, and those
of the remaining set being of a height correspond
ing to “high” level. When the inserts have been
properly placed in the groove, the required ski
bar is bad.
The exact nature of the present invention will
become apparent from the following description
when considered in connection with the accom
panying drawing, in which:
Figure l is a perspective view of the bar mem
ber forming part of a skip bar constructed in ac—
cordance with the present invention.

50 ‘and 60 column length, as indicated. The in
serts of one set may be of a Vertical width or
height corresponding to the depth of groove 9
and thereby corresponding to “low” level as in
dicated at a in Figure ‘l. The inserts of another
set are of a height corresponding to “X” level as
indicated at b, and a third set may be provided
which are of a height corresponding to “high”
level as indicated at c. In the bar member shown,
the groove is 80 punch card columns long. By
closing the groove at one end, the inserts are
prevented from sliding out of the groove at that
end. The “low” level inserts are provided to
simply ?ll in the desired portion of the groove,
the ““ ” level inserts being used for the punch
or skip sections of the card, and the “high” level
inserts being used to automatically skip certain
columns on the machine. The inserts are pref
erably made of metal and ?t snugly in the groove
so that they will not jar out in use, but may be
removed by the use of a small pair of pliers. The
skip bar rack of the machine has a holding device
that keeps the inserts from sliding to the left or
out of the groove at the locked end of the bar

beveled as at H obliquely of the bar member so
that the lever which rides along the top of the
skip bar and the inserts will not catch on the
latter and stop the machine.

that there are sui?cient inserts of various length
