4 Claims. (Cl. 164-112)
This invention relates to certain new and useful
improvements in perforating machines.
More particularly, this invention relates to per
forating machines such as used in connection
Ul with perforation of cards used in the well known
Hollerith system of accounting in which perfo
rations are made on a card at selected index
points, which are differentially located with re
spect to each other. Such a punch is shown in
the Hollerith patent No. 682,197 issued September
10, 1901, which is designed to perforate the well
known Hollerith card. In a punch of this type,
each time a column is perforated the card carri
age automatically steps ahead to present the next
column for perforation. This method of opera
tion is satisfactory whenever a regular prear
ranged form of perforating is to be used, particu
larly wherein all the information is punched on
the card at one punching operation, which meth
od largely predominates. There are however
many instances of statistical analysis where in~
formation is acquired from time to time which
must be perforated on cards which have already
been perforated in many columns. An example
l of this type of analysis is used in hospitals and
sanitariums where case histories of the individual
patients are kept on cards. Codes are used for
the variousv diseases and inñrmíties that are en
countered and these codes are punched on the in
dividual patient’s card in accordance with what
ever malady the patient is afflicted with.
The columns to be perforated thereforev may
vary considerably with each succeeding card,
there being many columns in each card in which
perforations are entirely omitted in which no two
succeeding cards will require the same columns to
be passed with no perforations. It is essential
therefore that the machine for perforating these
cards must be flexible for quickly locating the card
40 at' the proper column with ease and accuracy to
be sure that when located the index points on
the card will be in proper alignment with the
It is an object of this invention to provide a per
45 forating device in which the object to be perfo
rated may be moved quickly to any position to be
Another object is to provide mechanism for
locking the card into positive position in align
50 ment with the punches.
A still further object is to provide locking mech
anism for locking the machine against >punching
until the card is positively located for the punch
ing operation.
Still another object is to provide Ya locking

Various other objects and advantages of my in
60 vention will be obvious from the following particu
lar description of one form of mechanism em
bodying the invention or from an inspection of the
accompanying drawings; and the invention also
constitutes certain new and novel features of the
construction and combination of parts herein
after set forth and claimed.
In the drawings:
Fig. 1 is a plan view of the machine. ‘
Fig. 2 is a partial longitudinal section showing
the punching and locating mechanism.
Fig. 3 is an enlarged detailed cross section show
ing the locating and locking mechanism.
A base Iû is provided with a trough-like run
way II of proper width to receive a card which
may be moved longitudinally of the base. A slot
I2 is provided in the base which runs its entire
length and in which runs the card carrier. The
card carrier comprises two end pieces I3 and I4
which are connected to a bar I5.
The distance
between the end pieces is substantially the length 20
of the card to be perforated. A small spring
pressed member I6 is provided on the end-piece
I3 to hold the card snugly against the end-piece
I4 and thus hold it in fixed position. The bar I5
is provided with rollers I‘I running on tracks I3 25
which are cut into the bar I9 fixed to the base
of the machine. The end-piece I3 is connected
to the bar I5 by a member 20 on which is mounted
a handle 2| for the purpose of manually sliding
the card carrier back and forth by virtue of the 30
rollers I'I and the roller 22 which rests on the base
of the machine. The handle 2l is provided with
a plunger 23 which is biased upwardly by a spring
24. The lower end of the plunger terminates ad
jacent the bottom of the slot I2 and is adapted to 35
cooperate with apertures 25 located in spaced re
lation to each other along the bottom of the slot
I2. Adjacent these apertures on the underside of
the bed plate opposite to the plunger 23 is a bail
26 extending longitudinally of the machine in line 40
with the centers of all the apertures and for a
distance covering the length of travel of the end
plece I3.
This bail is supported at each end of an arm 21
ñxed to a shaft 28 which is journaled in the sup 45
porting webs 29 of the base ID. Fixed to one end
of the shaft 23 is an arm 30 which is biased in a
counterclockwise direction as shown in Fig. 3 by
a spring 3|. The upper end of said arm is bifur
cated and engages a pin 32 (Fig. 2) ñxed to a comb 50

ber 34 mounted on the side frame of the key sup

The comb 33 is provided with a seriesV of up
