10 Claims. (Cl. 164—113)
This invention relates to improvements in
methods and means for making and utilizing rec
ords and has particular reference to the punc
_ turing means.
This is a division of my applica
5 tion Ser. No. 380,687, ?led July 24, 1929, now Pat
ent 1,916,232, granted July 4, 1933.
An object is to produce novel means for pro
ducing such a card or other record.
Other objects will appear from the following
10 description and the appended claims. An illus
trative example of a mechanism for carrying the
invention into effect is shown in the accompany
ing drawings, in which:
Fig. 1 is a fragmentary front elevation of a
record making machine, parts being broken away
for clearness.
Fig. 2 is a vertical front to rear section of the
Fig. 3 is a diagrammatic view of the essential
features of the same.
Fig. 4 is a fragmentary vertical sectional view
whereby sorting and tabulating has been effect
There has also been suggested a means for
producing imperforate records by depositing elec
tric conducting material in spots on the surface
of the record material and then using a pair of
contacts for translating purposes.
The present
invention differs from both of these methods of
producing the record by making minute punc
tures or perforations through a record sheet to 10
indicate the data, and then passing an electric
discharge through these punctures for effecting
translation and utilization of the records. The
minute punctures may be made in various ways
as by an electric discharge or a needle prick.
In the drawings, I have shown my invention 1
in a machine having many characteristics of
what is known on the market as the Powers punch
and Powers tabulator. This is, however, merely
by way of illustration, and not essential, as the if i)
principles involved are susceptible of embodiment
of a tabulator provided with elements of the
in many and various forms all coming within the
scope of the invention. Many of the features
utilized are also shown in my pending application

Although it is conceded that the smaller the
hole used in a record, the stronger and more
compact the record may be, it has been found
impractical in both electrical and mechanical
machines, due to limits of interpreting means, to
use records having holes smaller than those gen
erally adopted.
In the present instance there
has been devised a means of utilizing records
having minute holes or perforations which is
free from the limitations of methods heretofore
This type of record and means for interpret
ing the same is adapted for use in control of a
wide range of automatic and semi-automatic ma
chines such as Jacquard looms, accounting ma
chines, etc. I have chosen by way of example
to illustrate the invention as used for controlling
an accounting machine, though this is not to be
considered as limiting the scope of the invention
50 in any Way.
Machine accounting has been effected for years
by ?rst producing a record card or the like hav
ing perforations punched therein, such perfora
tions being of sufficient size to permit the pas
55 sage of a pin or an electric brush therethrough,
The record making machine
Referring to the drawings in detail, the rec—
ords are produced in a machine having the gen
eral characteristics of the machine shown in
the patent to W. W. Lasker, 1,305,557. In such a
machine there is already known to be card or
record feeding and ejecting means, and a trans
versely movable carriage, which travels from col
umn to column of the card. Escapement mecha
nism, back-spacing mechanism, carriage return
mechanism are already well known in such de
vices. These well known elements will not be
described in detail, but the general positions of
such elements as are directly involved herein will
be indicated. Thus the record card It] is fed
by rollers ll into a station 12 from which it is
later ejected by friction rolls l3 and ejector rolls
M. The carriage is indicated generally at I5.
One of the number recording keys is shown at It,
and the operating key at H. While in the Powers
machine on the market operation of the operat
ing key effects (1) punching of the card, (2)
carriage return, (3) ejecting of the punched card
and feeding of a new card to station 12; in the
present instance the operating key effects only
the last two and does not effect the puncturing,
this being done upon depression of the number
keys as will be hereinafter set forth.
In the Powers machine now on the market the
record is fed between a pair of perforated plates,
through the perforations of which punches are
adapted to be thrust to punch apertures in the
record. In the present instance, however, there
are two imperforate plates spaced apart and
indicated generally as If) and I9. Each plate is
made of “Bakelite” or similar insulating mate
rial into which is molded or otherwise perma
10 nently ?xed a plurality of strips of conducting
material. The strips 20 of the plate l8 are
arranged to extend cross~wise of the card from
top to bottom thereof,~that is, each strip 20
extends along a respective data column of the
15 card, there being as many strips 20 as there are
data columns on the card. Each strip 20 has
its lower edge formed with a plurality of dis
charge points 2|, of which twelve are shown as
this is the usual number of data positions to
20 a column on records as at present used in the
Powers machine. The several strips 20 and their
points 2| are insulated from each other by the
general insulating substance of plate |8,—it being
understood, however, that points 2| are flush
with the lower surface of plate l8.
In like manner plate l9 has molded in it a
plurality of strips 22 running cross-wise of the
card from side to side and each formed with a
plurality of discharge points 23, one point 23 for
each strip 20 and in registry with the respective
point 2| thereof. Each of the points 23 is ?ush
with the upper surface of the plate l9.
Each of the strips 22 is connected by a respec-I
tive lead 24 to a switch arranged at the number
key IS with which it is speci?cally associated.
The operation of the key mechanism will be here
inafter described.
Each of the strips 20 is connected by a lead 25
to a connection box the construction and purpose
40 of which will now be set forth.
The connection bOsa-In my pending applica
tion Ser. No. 324,427, which is the same as my
said German patent, I have shown a connection
box, such as I propose using in the present
» instance. This box consists essentially of a frame
26 having a plurality of vertically disposed
V-shaped strips 21 of conducting material suit
ably insulated, and a plurality of horizontally
disposed rods 28 upon each of the latter of which
is mounted a slidable connector 29 adapted to
be moved to connect its respective rod 28 with
any desired one of the strips 21. In the present
instance each of the leads 25 is connected to a
respective one of the rods 28 and each of the
strips 21 is connected by a lead 30 to a respective
one of a plurality of electrically conductive bars
3|. The bars 3| are preferably molded in a plate
of “Bakelite” or other insulating material. The
bars 3| must be insulated from each other and
(El) may be supported in any desired manner from
the framework of the machine and below the car~
riage. It will now be understood that by means
of the connection box any desired one of the
bars 3| may be connected in circuit with one or
more of the strips 20.
The carriage.-—The carriage I 5 is provided with
a downwardly extending arm 32 which carries
a spring contactor 33 arranged to traverse the
bars 3|, there being one bar 3| for each posi
tion of the carriage. As the carriage moves
from one position to another, the contactor 33

end arm
of the
secondary winding 35 of a spark coil 36. The
other end of Winding 35 is connected by a lead
31 to a contact plate 38 at the recording keys,
which may be common to contactors 39 of the
several key switches, contactors 39 being con
nected respectively to respective leads 24. If the
arrangement of the keyboard is not such as to
permit 38 to ‘be common, a plurality of contacts
may be used and all be connected to the lead 3“!
in any suitable manner.
The keyboard.—'l‘here is provided a plurality
of recording keys l6 having stems 4| which are 10
guided in suitable supporting structures as at 42
and 43, the stems operating Bowden wires 44 to
eifect escapement or step-by-step travel of the
carriage |5 in a manner well known in the art.
Each stem 4| is provided with a collar 45 of 15
insulating material which, upon depression of the
respective key is adapted to close two switches.
There is one key for each side-to-side row of the
card, or, in other words, for each strip 22. One
of the switches at each key comprises the con 20
tactor 39 and contact 38 above described while
the other comprises a contactor 46 and a contact
47. The several contactors 45 are connected by
a lead‘ 48 to one side of a source of electric sup
ply 49 while the several contacts 41 are con 25
nected by a lead 50 to one end of the primary
Winding 5| of the coil 36. The other end of
winding 5| is connected by lead 52 to the other
side of the source of supply 49.
When a key is depressed it ?rst causes collar 30
45 to close switch 46-41 and thereafter switch
38-49 whereby current is ?rst turned through the
primary circuit including 5|, thereby, as switch
46-41 operates, inducing a high tension current
through the secondary and directed to the strips 35
l8 and I9 which are in circuit respectively with
carriage arm 32 and operated contactor 39. The
strips l8 and IS in this circuit have a discharge
point of each disposed opposite that of the other,
and a spark is caused to jump from one to the
other thereby puncturing the record card at the 40
desired point. This puncture will be minute, but
experiment has shown it to be suiiicient for
reading or sensing purposes by a machine con
structed in a manner which will be presently
It will now be seen that the position of the car
riage determines which of the bars 3| shall eiTect
control, the connection box determines which of
the strips 20 shall be controlled by the sev
eral bars 3|, and the keys l6 determine which
of the strips 22 shall coact with strips 20, where
by the exact location of the data puncture or
punctures is determined.
Sensing or data utilizing machine
Turning now to the machine for sensing or
utilizing the record cards, in machine account
ing two such machines are usually employed,via, a‘ sorter and a tabulator. Inasmuch as 60
sensing means may be utilized for one of these
machines and similar sensing means utilized in
the other, I have shown the sensing means as
applied to a tabulator only. It will, of course,
be understood that the same principle and simi
lar sensing means could be built for translating
the record on the cards for use in other machines
of automatic or semi-automatic nature such as
Jacquard looms.
Known tabulator mechanism.~—In this connec
tion, attention is ?rst invited to the showing of
certain mechanism taken from my application
Ser. No. 324,427, which is the same as my Ger
man Patent No. 524,293, above referred to. Re
ferring to Fig. 4 of the present speci?cation, 53
represents the usual stops of a Powers tabulator,
which stops are selected and raised by denomina
tional ?ngers 54. Each ?nger 54 is carried by a

the strips ‘H is connected by a lead 83 to a re

of the high resistance relays 80.
A source of_ electric supply is shown at 86 and
has itspositive line 81 connected by leads 88
the particular stops 53 determined by the data
recorded on the record being sensed.
The stops El, of which there is one for each
slide 55, are carried by respective armatures iiI
of magnets {52 operable from the record card
to one side of each of the magnets 62. The nega
tive line 38 is connected by leads 95 to the arma
tures SI of relays 80. Each armature is provided
at its free end with a contactor adapted to en
in a manner to be hereinafter described. The
universal bar 56 is operable by a rock arm or
20 arms Ii?» connected by a link or links 64 to operat
ing means such as a cam 59 driven from the
main operating mechanism of the machine.
When all of the stop-operating ?ngers 54 have
been moved to positions determined by the rec
25 ord, they are all lifted by a universal frame 65
gage contacts 92 and 93 when the relay is ener
gized. Contact 92 is connected by a lead 94 to
arespective magnet 62, so that when a relay 80
is energized its armature closes the circuit through 20
the corresponding’magnet 62, and the latter in
stantly raises its stop 51.
Self circuit for relay-The contact 93 is con
nected to one side of the relay 80 by a lead 95,
while a lead 95 connects the other side of the 25
rocked by an arm 66 cooperating with a cam 51
driven from the main operating mechanism of
the machine. As ?ngers 5d are lifted, they raise
the desired tabulator stops 53 to control the reg
30 istering and recording mechanism of the tabu
lator head in a well known manner.
V Operating the magnets.—The magnets 62 are
energized by means differing from the prior art
and from my prior application, and such means
35 will now be described.
In the Powers tabulator as at present on the
market, the cards are fed intermittently to a
sensing position, then sensed, and then ejected.
In the present case, the card is fed through the
4:0 machine in a single continuous movement and
sensed in transit. The card feed rollers and
picker knife of the known mechanism are there
fore driven in timed relation to the movement
of the above described universal bar 56 and slides
. 55, so as to bring the proper teeth 58 into co
operative relation with stops 5'! at the instant
that the corresponding digital row of the card
is in sensing position.
The card passage is indicated at 68 and is
- formed by two plates 69 and it which are pref
erably of “Bakelite” or similar insulating ma
terial and which hold a plurality of conducting
strips ‘ii and ‘I2 insulated from each other by
the substance of the plates. The strips ‘ii are
arranged in the vertical planes of respective
strips l2, and are provided with discharge points
‘I3 directly over similar points ‘M on strips 12.
The points 73 and ‘M are substantially at the
middle of their strips.
The plates 69 and ‘iii are cut away at the points
and l. to permit the passage of insulating
between the points. These disks con
tact the record and are rotated by the operat
ing mechanism, the several disks being secured
to two shafts and taking the place of one pair
of feed rollers of the Powers machine. They
space the elements 73 and ‘I4 and prevent any
possible cross-jump of the electrical discharge.
Each of the strips ‘I2 is connected by a lead
‘iii to a respective secondary winding TI of a
coil “it, the other end of each winding 'I'I being
connected by a lead 19 to one side of a high
resistance relay es.
The other side of each relay
8% is connected by a lead 8i to a respective one
the elements 82 of a connection box similar
relay to the respective positive lead 88. Conse
quently, when the relay is energized a circuit is
closed from 88 thru 96, the relay, lead 95, contact
93, armature 9| and lead 90 holding the relay
operative even after the card has passed con
trolling position. In order that this circuit may
be broken toward the end of the cycle, I provide
switch 98 in the line 89 which is opened by uni
versal bar 56 at each operation thereby releasing
any armatures 9| which may have been moved 35
to circuit closing position.
Spark coil‘ connections-J1me primary winding
99 of spark coil 18 is connected at one end by
a lead I80 to the positive line 81, and has; its other
end connected by a lead Ilil to the armature I02 40
of a magnet I03. When the magnet I03 is de
energized its armature I02 brings a contactor
I94 into engagement with a vibrator I05. The
vibratorv Hi5 is formed with a lug I06 which rides
on the periphery of a disk I01 insulated from the 45
rest of the machine and driven from the main
operating mechanism of the machine. Member
I65 is also formed with a ?nger I08 cooperatively
related to a contact I09 connected by a lead III!
to the negative line 89. The disk Iil'l is formed
with a plurality of lugs or teeth III adapted to
contact lug IllB and vibrate member I05 so as
to break the contact at |Il8-I09, thereby effect
ing interruption of the circuit through primary
'99. This is necessary to e?ect electrical dis 55
Rendering spa?c coil ine?ectioe
It is desirable to throw the coil 18 out of action
when no car-d is being fed between points ‘I3 and
‘M, and for this purpose I provide two more strips
‘I2 (indicated at 12A), than there are strips TI,
and located at opposite ends of the plate 10. Co
operating with these extra strips 12A are spring
contactors II2 which contact the extra strips 65
72A when no record is between plates 69 and
‘Hi. When a record is fed between the plates
the contactors H2 are raised to ineffective posi
tion by the edges of the record. One of the con
tactors H2 is connected by a lead H3 to one side
of the magnet I03, the other side of the magnet
.being connected to return by a lead H4. The
corresponding extra strip 12A is connected by a
lead H5 to the positive line 81. Whenever no
record is in cooperative relation to points 13 and 75

is closed through magnet I03 which raises its
