When a digit is to be expressed on the com
binational hole code card it is, by suitable mech
anism in the perforating device, translated from
the realm of mathematics'into that of mechanics
g5 and expressed in the form of an arbitrary code
upon the record card, such code having no mathe
matical properties whatever but being arranged
In the past, many variatlonshave been devised 15
for carrying out both systems, but all have ‘de
pended, either upon the digit index position with
its attendant extravagant use of record material,
or upon the arbitrary and ?xed combinational
code with its complicated and expensive analyzing 20
and translating mechanism.
The system forming the subject matter of my
invention eliminates the necessity of complicated
analyzing and translating mechanism and yet
provides means for expressing a number great- :5

necessary or desirable to pre-analyze the digit
and express it in the form of components.
Whether the digit is expressed by a single or plu
rality of perforations, no complicated analyzing
or translating mechanism is required in the pres
‘ent machine since all necessary analyzing is
done in the process of punching the card and
this pre-analysis has in no way destroyed the
mathematical properties of the digit even though
10 it has been broken down into constituent parts,
and accordingly requires no translation from
mechanical to mathematical form.
'
My invention comprises, therefore, a new and
useful system of record reading and control,
15 which is generically distinct in its operation from
anything that has preceded it, and one of its im
portant objects is to simplify the record reading
and control mechanism.
.
Another of the more important objects of the
invention is to reduce the amount of record ma
terial used in record controlled machines.
A further object of the invention is to provide
‘means for reading a plurality of index points,
such as perforations, in a record card by a single
sensing element in combination with a simpli?ed
mechanism for registering the values of such
index points.
»
Another object of the invention is to provide
means for correctly reading and registering data
expressed by a single hole or other index point
or by a plurality of holes or index points, when
each of such holes or index points has a distinct
meaning or value, and in which the plurality of
holes, in order to express a digit, does not neces
sarily conform to any rigid code. The advantage
of this feature of my invention will be further
apparent when it is understood that with arbi
trary code records in use, the average person han
dling such records is unable to read the data rep
40 resented by the perforations since they have no
more. If ?ve perforation positions are used the
five values are selected in the manner described
above so that every digit may be expressed either
by the value of a single position or an aggregate
value of two or more positions. A detailed de
scription therefore need not be given of the man
ner of selecting values for a five position card.
In order that the invention may be more clear
ly described I have chosen the combination,
1, 2, 2, 4 as representing the respective values of 10
the perforation positions in each column of the
record in the following more detailed description
and it is to be understood that I do not thereby
limit my invention to that speci?c combination
but that the invention is applicable to all possible
combinations of values in groups of four or more.
A series of sensing elements is provided to en
gage the perforation positions on the card. Each
one of these sensing elements in conjunction with
the perforations in its respective column of the 20
card controls the movement, and with certain
other means also the amount of movement, of an
accumulator or a registering member associated
with each sensing element. Inasmuch as a sens
ing element functions only when a perforation
occurs in the position in the column being read
at a particular instant, there is consequently no
movement of the registering members in such
positions as are unperforated.
Further objects, advantages, and features of
my invention will more fully hereinafter appear
taken in connection with the accompanying draw
ings, in which: '
Fig. 1 represents the preferred form of perfo—
rated record card for controlling the operation
of the machine illustrated in Fig. 2.
Fig. 2 is a perspective view of the preferred
form of an electrically operated machine con
trolled by such cards, the electrical connections
and other parts of the machine being illustrated 40
mathematical signi?cance, and therefore it has
heretofore been the practice to provide elaborate
more or less diagrammatically and some of the
parts which are not conducive to an understand
secondary mechanisms for interpreting and print
ing in characters the meaning of the code in some
ing of my invention having been omitted entirely.
Fig. 3 represents a drum upon which is mount
ed the commutator 34, a development of which
is shown in Fig. 2.
The form of perforated record card employed
45 position on the card adjacent to the combina
tional holes for each column. Such mechanism
is not required to prepare the cards which the
present invention is capable of reading, since
with the machine to be described herein will now
each hole has its own value distinct from all
50 other holes, and can be so marked upon the
card. By a simple primary addition of the holes
of any group, the operator is able to read such
group.
In my system, a value is therefore assigned to
55 each perforation position upon the record card
and these values are so selected that the several
be described. Referring to Fig. l the values 1, 2,
positions when taken singly, or in multiple with
assigned values of other positions, will sum up
to and include the highest number or value de
to sired in the system. This number is preferably
nine in accounting machines using the decimal
system. It is also desirable though not neces
sary that the values assigned to each position on
the card should not total or aggregate a num
65 ber greater than the highest number to be ex
pressed. Values which are capable of expressing
consecutive digits when taken singly or in the
aggregate with other values may be such combi
nations as 1, 2, 2, 4 or 1, 1, 2, 5 or 1, 1, 3, 4 or
70 1, 2, 3, 3, or 1, 2, 4, 6. It is clear that many groups
~1
of values of four may be selected as shown by
the above examples which do not recite all the
possible combinations thereof.
The system is not restricted to four perfora~
tion positions but will apply to five positions or
so
2, 4 are shown as having been assigned to the
four value or perforation positions in each column
on the card at the points VI, V2, V3 and V4
respectively, and so printed thereon. The card,
in addition, may be divided into fields or sections
each comprising a plurality of columns of perfo
ration positions as indicated at SI, S2, etc. and
may be paper or any other suitable insulating
material. Throughout it is to be understood that
a perforation is only one of the many forms of
index points that may be utilized.
60
In order to explain the manner in which the
values assigned to the perforation positions are
used, let it be assumed that the number 7324 is
to be recorded in the first and also in the second
?eld of the card shown in Fig. 1. As previously
explained the perforation positions in each col
umn are arbitrarily selected as having the values
1, 2, 2, 4 and therefore the thousands digit 7
of the desired number is obtained by selecting
values whose sum is '7 which would be the posi
tions having values of 4, 2 and 1 in the columns
pl. To secure the hundreds digit, positions hav
ing a summed value of 3 are selected which
would be values 2 and 1 in the columns p2. Since
positions having values of 2 and 4 exist in each
2,106,801
of the columns the tens and units digits are
secured by a single perforation position in p! and
94 respectively.
Since there are two perforation positions in
each column whose value is 2 it is apparent that
a single number may be recorded in many differ
ent‘ways depending @upon which position having
a value of 2 is selected to represent a number
alone or when summed with other values in the
10 column to secure the desired number. Again in
stead of utilizing a perforation having the value 4
to secure the number 4, this number may be ob
tained by a sum of the two positions having a
value of 2. It is seen therefore that a single num
ber
may be recorded in a number of different
15
ways merely by selecting different’ combinations
of values or value positions and this has been il
lustrated in Fig. 1 in which both the first and
second ?elds represent the same number'7324
20
yet different perforation positions have been»
selected.
' -
It will later be shown that the record control-l
ling machine illustrated, described and claimed
herein is capable of reading either of the com
25 binations shown, or ‘any other combination, with
equal facility, and accordingly the system has the
advantage of great ?exibility. This advantage is
re?ected in savings of both record material and
labor. Because of the ?exibility of my system
30 upon which the present application is based,
many errors in punching may be corrected, with
out in any way affecting the accuracy of the ?nal
results.v To recite simple illustrations, if the

proceed to describe in detail.
Referring to Fig. 2.11 quantity of record cards
such as those described above and shown in Fig. 1
are placed upright on the platform 2 with the
longitudinal rows of perforation positions having
a value of 4 at the bottom and are fed, one by
one. by any suitable means to the position indi
cated by card I for cooperation with sensing
elements 20A, 20B, 200 etc., securely held by a 10
suitable supporting bar 20. I have shown the well
known reciprocating cross head stripper 3 slid
ably mounted in suitable guides and carrying a
plate to which projects over the top of the first
card slightly less than the thickness of said card 15
for feeding the cards from the platform 2, al
though the cards may be fed by hand or any other
suitable means. The stripper is driven by a con
necting rod 4 eccentrically pivoted to a disk 5,
mounted upon a shaft 0 which is so connected
by gearing (not shown) to the shaft, it that the
stripper, at the proper time, delivers the card
to the feed rollers ‘I’ and ‘I’ the latter being driven
at. a speed having a ?xed relation to shaft III.
A cylindrical feed roller 8 is suitably secured
to the shaft Ill and has an outer-surface of some
‘electrical conducting material the purpose of
which will be explained later. A gear I I, secured
to shaft Ill, meshes with a gear I! loosely mount
ed upon a shaft it.

that many corrections of this character can be

The preferred form of the device which is used
for perforating the card, being another inven
tion, is not shown nor described ‘herein.
In its broad aspect the perforated record card,
in order that it may properly cooperate withthe
machine which it is adapted to control, is ac
curately cut to a predetermined size and com
‘ prises a plurality of columns accurately spaced in
relation to one another and to the lateral ex~
tremities of the card and each of which columns
consists of less than nine perforation positions
located at predetermined distances from both
ends of the card and from one another and accu
able clutch member I‘. The lever ISA is rocked
upon its pivot by means of an electromagnet I3
cooperating with an' armature secured to the
upper end of lever "A, a spring I30 being pro
vided for normally holding the armature with
drawn from the electromagnet and the clutch
in open or disengaged position.
A bar 2. is constructed of insulating material
and is held rigidly in position between the side
members of the frame of the machine (not shown
in the drawings) and is drilled to receive a series
of brushes or sensing elements 20A, 2013, "C etc.,
the center distancesbetween said brushes being
equal to the spacing of the ‘columns on the record
card. The extremities of the brushes extend

tions, each of said positions when perforated

the highest number to be expressed by any single bar 20 is set at an angle as shown in Fig. 2 to
combination of perforations. The machine oper
ating upon and controlled by such a card may
obviously assume a variety of forms.
Conse
quently the machine itself, which is illustrated,
described and claimed herein is expressely under
stood to be merely the preferred embodiment in
sofar as that aspect of my‘: invention is con-;
facilitate the passage of the cards between the
brushes and the roller 8 with which the brushes 70
are normally in contact without injury 'to either
themselves or the cards. The number of brushes
corresponds to the number of columns of per
foration positions upon the record card. A brush
8A contacts with the surface of the roller 8 and 75

is connected to a source of energy such as a bat
and which are well understood by those skilled
tery 50, the circuit being completed through the
in the art, that an explanation of their operation
is unnecessary to a complete understanding of
the present invention.
A commutator or control member 34 is adapted
to be connected in series with the electromagnets
brushes which are connected to the opposite
side of the source through mechanism to be de
scribed when a perforation in the card appears
opposite said brushes. A card, as it is fed down
from the platform 2, passes between the roller 8
and the brushes 20A, 28B, etc., thereby breaking
the contact between the brushes or sensing ele
10 ments and the roller 8, which contact is not re

pieces 35, 36, 31, 38, 38, 40, 4| and 42 imbedded 10
established until the card has passed beyond the
therein or mounted thereon in any suitable man
roller 8 or unless a perforation exists in a column
of the card in which case a brush or sensing
element comes into contact with the roller
ner. A development of the surface of the com
mutator is shown in flat perspective in Fig. 2 to
enable its function and operation to be more
readily understood, and in its preferred form it 15
is mounted upon or forms the cylindrical surface
of a drum, as shown in Fig. 3, which drum is
15 through the perforation.
It may be stated at
this point that when the roller 8, through a per
foration, is engaged by a sensing element a cir
cuit is closed and certain operations take place.
The downward movement of the card having
20 been arrested by other mechanism, means are
provided to operate a registering device or ac
cumulator for a period the duration of which is
proportional to the predetermined value of that
perforation. At the end of such period the move
ment of the record card is reestablished by other
means to be described. The mechanism for set
ting the counter mechanism or accumulators into
operation upon the closing of the circuits will
now be described.
80
22A, 22B, 22C, 22D, etc., through the perforations
in the card and is constructed of non-conducting
The conducting wire 2|A connects the brush
20A to an electromagnet 22A which controls a
clutch member 24A by means of the pivoted
armature 23A. The clutch member 24A, in a
well known manner, operatively connects the
35 constantly rotating shaft 33 with the index wheel
25A rotating it an amount dependent upon other
mechanism which will be described.
The index wheel 25A, which is one form of a
differentially adjustable device, is provided with
40 ten index positions marked around its periphery
in the usual manner and is freely mounted upon
the driving shaft 33, so that it does not turn
with the shaft 33 except when selectively con
nected thereto by the engagement of the clutch
45 member 24A with one of the ten clutch teeth
with which the index wheel is equipped. This
mounted upon a shaft 41 driven from shaft l6.
It is clear however that the commutator may be a
20
disk or'may take any other suitable form.
The conducting pieces or control elements 39,
40, 4| and 42 are of different lengths or dimen
sions, the reason for which will be explained later
and their lengths are proportional to selected
digital values of the various index point positions 25
so that one or more of the elements taken together
will produce dimensions or lengths increasing
proportionately in units of one and in the same se
quence as the assigned values for the perfora
tions in the cards. Since in this case the values 30
of the perforations have been selected as 4, 2, 2,
end 1 the length or dimension of the conducting
piece 39 is four times that of piece 42, and 48
and 4| are twice as long as conducting piece 42.
Similarly if the values of the perforations had 35
been taken as l, 1, 2, 5, which is one of the com
binations previously pointed out, then contacting
piece 39 would be ?ve times as long as the piece
42, 40 would be twice the length of 42, and 4|
would be equal in length to 42. These conducting 40
pieces 39, 48, 4| and 42 are furthermore aligned
with each other so that a single set of brushes
engages the pieces in sequence as the drum ro
tates.
If the contact pieces were arranged upon
a disk then they would be positioned upon a circle
or at the same distance from the center of the
clutch acts in a manner similar to the clutch
|4--|4A, the same being more fully described in
the Hollerith Patent 945,236 and is so well under
disk. The contacting pieces 35, 36, 31 and 38 are
also aligned with each other and are placed paral
50 stood by those skilled in the art that it requires
pieces 38, 40, 4| and 42. Pieces 36, 31 and 38 are
of equal length and located opposite the insulated
spaces between the pieces 39 and 48, 40 and 4|, 4|
and 42, whereas the conducting piece 35 is con
siderably longer and is located opposite the in
sulated space between the adjoining conducting
pieces 42 and 39.
no detailed explanation here.
indows (not
shown) may be located over the positions of the
counters at which zeros are shown in the draw
ings, and through these windows readings may be
taken. Although only four of such electromag
nets and index wheel units are shown in the
drawings it is to be understood that each of
the brushes may be connected to a similar elec
lel to and in close proximity with the conducting
Brushes 45 and 48 are mounted upon an in
sulated holder (not shown) so that they contact
tromagnet which controls a separate index wheel - with the conducting pieces 39, 40, 4| and 42 and
in the same manner as the single unit described
above and the wheels grouped into independent
counters. It is to be noted however that all the
index wheels may be driven from the single
shaft 33.
In registering devices of this class there are, of
course, other supplementary mechanisms re
quired, such as means for carrying, or transfer
ring from one wheel to the next of higher order,
when used for addition, resetting means, means
for selectively associating any column of the card
with any particular registering member, and
mechanism for performing other desirable sec
ondary functions.
There are however so many
well known and satisfactory methods of accom
plishing these other results, which I may utilize
brushes 43 and 44 are also so mounted upon the 60
same or a similar insulated holder adjacent to
brushes 45 and 46 that they contact with conduct
ing pieces 35, 36, 31 and 38 as the commutator
rotates. The brushes 43 and 44 are connected
in series through lead 54 with the electromagnet
l3 and therefore these brushes together with the
commutatorcontrol the current energizing this
electromagnet.
The conducting pieces and
brushes are so ‘positioned in the manner described
that a circuit exists at the commutator between 70
brushes 43 and 44 or between brushes 45 and 48 at
practically all times although a momentary de
lay in making one circuit after the other is broken
is preferable.
A brush l8 similar to the sensing element 20A 75
2,106,801
is mounted upon the insulated holder 28 at its
end and normally engages the conducting roller
8, when no card is passing over the roller, in
the same manner as the sensing element 28A
but differing therefrom in being outside of the
?eld containing the columns of perforations posi
tions but in the path of the card. This brush is
electrically connected by the lead 38 to an electro
magnet 29 of a relay mechanism which electro

38, I9, 8, 8A, 53 and» power source 58, which car
ries the necessary current to energize the electro

the card comes between the roller 8 and element

28 is no longer energized to hold armature 28
thus enabling the spring 28A to bias the armature
into contact with point 32 thereby closing the 10

which normally holds the armature in contact

When the card has passed completely by the

how it is generated or produced, which is utilized
and contemplated by the invention. Again other
means could be employed for delivering current
to roll 8 without changing the operation of the
machine. I have constructed the commutator
as described to provide means for breaking the
current at the commutator rather than at the
card where an arc is undesirable.
The brushes
held by the insulating bar 20 are made up by
grouping a multiplicity of small wires and as
preferably arranged the lower portion of the
brush is still in contact with B through the upper
portion of the perforation for sufficient time after 60
the card has begun to move downward to permit
38, 40, 4| or 42 to de?nitely leave the brushes
45 and 46 before contact between the sensing
members 20 and roll 8 is broken thus causing the
current to break at the commutator.
It will be readily understood that other values
than those assigned to the card may be read
with equal facility by changing the relative dis
tances between 35, 36, 31 and 38 and changing
the lengths of the contact elements 39, 40, 4| and 70

card, or by otherwise providing means for hold
