This invention relates to tabulating machines, and more particularly to mechanism for transposing the meaning of readings taken from a particular record by such machines.

The present case is a continuation in art of our copending case Serial No. 108,834, led May 13,1926.

In tabulating machines heretofore constructed, -it has been usual to provide perforated record cards and to take readings therefrom by means of a single brush sensing the perforations in the card while the cards are in motion. In certain other tabulating machines a combinational hole record was provided which was sensed either by brushes or by a plurality of pins. In the latter case it was necessary to read the perforations with the cards at rest. Inasmuch as a particular type of tabulating machine is required to read each of the above mentioned type of records, it is desirable to provide a mechanism capable of reading one type of record and controlling thereby a machine normally capable of being actuated only by a different type of record.

It is therefore an object of this invention to provide a machine capable of translatin readings of one type into readings of a di '.ferent type.

Another object is to provide a machineK this invention ;-v

for controlling ajrecord actuated device of any desired type. By choosing the proper commutator arrangement, a set-up obtained from any particular type of record may sensed and used to actuate a machine normal; ly responsive to records of a diierent ty or the order of the 4readings may be ar itrarily transposed and used to actuate a machine in the new sequence;

Although the novel features which are believed to be characteristic of this invention will be pointed out with particularity in the claims appended hereto, the invention itself, as to its objects and advantages, the mode of 1ts operation and the manner of its organization, may be better understood by referring to the following description taken in connection with the accompan ing drawings forming apart thereof in which f Fig. 1 is an elevation of the translat' mechanism constructed'in accordance witl Fig. 2 is a'plan view ofa portion of a bank of translating devices showing the manner of attachment to the accumulator of a tabulating machine;

A further object is to provide for sensing a direct record or reading and obtaining another reading which is a complement thereof The above objects, and others which will be apparent as the nature of the invention is disclosed, are accomplished in accordance Vwith the present invention by providing a mechanism capable of setting up and temporarily retaining contacts in accordance with a sensed record. The set-up contacts are used to complete a circuit to various segments of a stationary commutator which is then sensed by brushes and a reading obtained therefrom with this invention;

eferring to the figures more in detatll, the translating mechanism comprises a vplurality of units 20, (Fig. 2) one unit being employed for each index column of the controlling record. A portion of a bank of such units is shown in Fig. 2 associated with an accumulator or countmg mechanism 21. Each unit is integrally mounted on a base plate 22 (Figs. 1 and 2) ,and is held thereby in mesh with gear wheel 23 on main driving shaft 24 which here makes one complete revolution per card cycle. Current is supplied through contacts 25 when the unit is 1n position in the machine. This construction permits the units to be removed and interchanged at will. The -accumulator element is drlven. from shaft 24 through gears 26 and 27 (Fig. 2) in the usual manner. One form of accumulator to which this invention may be applied is disclosed in a patent to Lake, No. 1,307,740 dated June 24, 1919. Inasmuch as the accumulator and its actuating mechanism form no part of this invention a more detailed description is not given herein.

Gear 23 and cam 30 (Fig. 1) are attached to shaft 24 and revolve in conjunction therewith. Cam 30 is used to control contacts 31 whereby certain operations of the set-up mechanism are interrupted during a portion of a card cycle. Contacts 31 are opened during one half of each revolution of shaft 24 and closed during the other half of the revolution.

The set-11p mechanism 20 which will be rst described is driven from gear 23 through a driving train comprising gears 32, 33 and 34. Gear 34 is provided with a stepped cam 35 the purpose of which will be hereinafter described and a reset cam 36. The setl up mechanism operated by cams 35 and 36 is shown more in detail in Figs. 4 and 7. Magnet 37 is provided with four armatures 40 to each of which is rigidly attached an arm 41. Arms 41 are pivoted on rod 42 and terminate at their free ,ends in detents comprising undercut slots 43. Arms 44 pivoted on rod 46, are provided at one end with a set of contact elements A, B, C and D respectively, and at their other ends with projections 45 and 47. Projections 45 enter slots 43 in arms 41 and .normally lock the latter against movement.

As stepped cam 35 is rotated with gear Wheel 34, it successively depresses projections 47 on the various arms 44 and disengages projections 45 from -their retaining slots 43, re-

easing the corres onding arms 41 to ermit movement thereo upon energizationo magnet 37. Although each, of the four armatures is attracted whenever magnet 37 is energized only those armatures which are released by cam 35 at that particular moment are permitted to move, the other armatures being held in a stationary position by the detent means above described.

When the cam 35 has released a particular armature for movement and magnet 37 has at the same time been energized, the releas d armature 40 is attracted and together wi'i arm 41 is moved to the left (Fig. 7). The detent means comprising slot 43 in arm 41 and projection 45 in arm 44 is then completely released allowing the arm 44 to be given a slight counterclockwise rotational movement by the force of springs 50 untill a shoulder on the arm abuts on stop member 51 which prevents further movement. Projection 45 then prevents arm 41 from returnset as required and a reading derived there-` from in a manner to be later described, upon further rotation of gear wheel 34 reset cam 36 engages projections 47 and depresses the same releasing projections 45 from their retaining position on arms 41 and allowing arms 41 to be rest-cred to their original position in response. to a force applied by springs 52. Having assumed their original position they are again locked by the detent means comprising projections 45 and slot 43 above described. The device is then in condition to receive the next set-up in accordance with the subsequent record card.

The set-up mechanism just described is operated in response to record cards 53 (Fig. 8) which are successively passed under brushes 54. When ver a brush senses aperforation in the record card, contact is made to the cooperating metallic member 55 anda circuit completed through magnet 37 which is temporarily energized. Magnet 37 will then attract its armatures and the particular one which happens to be released by cam 35 at that intant will be moved to the left and corresponding arm 44 assumes and retains its new position.

A combinational hole record card similar to that shown in Fig. 5 is employed with this machine, each of the digits being represented by a particular combination of perforations in the A, B, C and D positions. Cam 35 is timed with respectto the .passage of record card'53 under brushes 54 so that brushes A, B, C and D (Fig. 7 are released successively at the exact moment that brush 54 traverses the A, B, C and D positions, respectively, of the record c ard. The result is that the coml bination set-up b arms 44 corres nds to the combination ofperforations in t e record sensed by brush 54.

Brushes A, B, C and D on arms 44 make contact with conducting strips 56 or 57 (Figs. 1, 6, 8 and 10) according to their respective set-up positions. The combination setup by mechanism 20 is analyzed by brushes 60 attached to ear wheel 32. These brushes make contact wlth the various segments of commutator 61 connected to conducting members 56 and 57. The construction of brushes 60 and their manner of arran ement may be seen by referring to Fi 3 wiich shows a sectional view thereof. rushes 60 are connected mechanically to the gear wheel 32 b means of metallic strips 62 which are'rigid y attached to wheel 32 and insulated therefrom by' means of insulating discs 63.

Commutators 61 are shown in detail in Figs. 6, 8 and 10 and in section in Fig. 3. They consist of cast or stamped blocks having rim portions 64 and contacting strips 65. The various contacting strips or segments are so interrelated that a circuit is completed by the brushes in a particular angular position, depending upon the set-up combination of contacts A, B, C and D. Brushes 60 are timed in respect to the commutator to send an impulsev through counter magnets 67, at the proper instant to operate the accumulator clutch to enter the amount indicated by the set-u combination code. Contact 31, operated y cam 30 (Fig. 8), is adapted to open the circuit to brushes 60 during half of each card cycle. Inasmuch as the brushes make one complete revolution per card cycle they are energized during one half of each revolution only. The half revolution during which contact 31 is open occurs while set-up mechanism 20 is being operated. During the second half of each revolution of brushes 60 contact 3l is closed. The circuit is then completed by brushes 60 to counter magnets 67 to permit energization thereof whereby the accumulator may be controlled in a manner well known in tabulating machines.

The operation of the device may be brieiy summarized as follows: During the first half of each card cycle the perforations on the card are sensed and the combination thereon set up and retained by mechanism 20. During the second half of the cycle the set-up combination is read by brushes 60 and a circuit is completed through the counter magnets to control the accumulatoror other record actuated device. Y

The particular set up shown in Fig. l0

serves to illustrate the action of the device.

PA and through commutator 61 at `the pro r time to effect an impulse to enter 3 into t e accumurevolution of brushes 60 (Fig. 10) it wi l be noted that, due to the arrangement of the commutator segments, when brush contacts A and C are lowered no circuit can be closed exce t at the 3 index point 'position of the mac line, at which point the brushes are set in Fig. 10. The circuit may be easily traced through the various wires, contact strips, commutator segments and brushes, if it be rememberedthat the two outer brushes 60 are electrically interconnected and the two inner brushes are likewise interconnected. The current enters throu h the C brush lators. Tracing the contacts made durin the and leaves through the A rush as indicated y Fig. 10 so that the entering impulses will occur at the proper times to enter 9 when zero is sensed, 8 when l is sensed and so lon. The commutator segment arrangement for this purpose is shown in Fig. 13. In the particular set up shown the brushes A and C have been shifted, indicating analysis of a record. card bearing the code notation for 3.

The brushes 60 and 62 are shown in the -act of passing the sixth point of machine operation. At this point a circuit is completed to enter 6, the nine complement of 3, into` the accumulators. It will be noted that for other shiftings of the brushes A, B, C and D according to the index point code in Fig'. 5

the entering impulse will always occur to y enter the complement of the number represented on the control card.

The operation of/the device thus far :described has been fou'the sole purpose of allowing a combinational record vto actuate a machine normally controlled by a record having a single perforation. However the device may be constructed to be actuated by a single hole record and the reading taken in complementary numbers or the order of the digits may be otherwise arbitrarily transposed as required.

The set-up mechanism for this purpose is shownin Fig. 9 wherein the cam 35 of Fig. 1 is replaced by four cams 70, (one for each arm 44) the details of which are shown in Fig. 11. Each cam 'p70 is designed to depress one of the arms 44 at the time a single index perforation is passing under one of the rushes 54 the combination of arms depressed corresponding to the particular code deter- 'llt mined upon to represent that index point.

If magnet 37 is not energized at that instant,

.arms 41 are not moved and arms 44 will again resume their normal position when released by cams 70.l Magnet 37 will Abe energized however at-a time corresponding to the posin tion of the index point perforated and armatures 40 attracted. Any arm 41 (Fig. 9) that is moved to the left by energization of magnet 37 is then held .by a pawl 71 (Figs. 9 and 12) which is drawn into ppsition by its spring and holds arm 41 in its set up position. Then as cam 70 continues on its revolution subsequent projections, for the purpose described above, on cam 70 will cause lever 44 to move up and down until it finally assumes its'true set up position which will be determined by the position of arm 41. Thus if any arm 41 has been moved to the left and latched in position by pawl 7l the arm 44 associated therewith will be drawn by spring into its set up position resting on stop 51, also if any arm 41 has not been moved to the left the arm 44 associated therewith Will retain the position shown in Fig. 9.

A combination having been set up by brushes A, B, C and D, it may bc analyzed byv brushes (Fig. l0) to produce anY impulse in the counter magnet at the required instant.

Final resetting is then accomplished by the long high projection (adjacent to arrow in Fig. 12) on cam 70 which first engages projection 47 on arm 44, moving arm 44 in a clockwise direction and then releases pawl 71 allowing spring 52 to move arm 41 into its right hand or normal position. Then When projection 47 on arm 44 drops off the long high projection on cam arm 44 will assume the latched position shown in Fig. 9.

If it is desired to read a complement instead of a direct number, the cams shown in Fig. llvmay be designed so that when the card contains a perforation 'in any position, for in- .stance the three position, the set-up combination of arms 44 will correspond' to its complement, or in that case to the digit six. On subsequent reading of the set-up mechanism by the brush 60, a six will be entered into the counter instead of a three.

, The machine is also adapted to transpose for complements other than the nine comple-- ments or to transpose to any given number or numbers which may be arbitrarily selected. For example, it may be desired to transpose the combination representing 5 on ya combinational hole card into a timed impulse representing 7. 7 is of course the twelve complement of 5 and if it is desired to comF plement the other digits also to 12 the commutator segments may be arranged for this purpose. On the other hand the vtransposi- V tion may be purely arbitrary and the commutator segments may be so arranged that the 3 will be transposed into a 5, for example, the 2 into a 7 and so on for entry into the counters.

These and similar trans ositions may also be effected from the usual ollerith cards on which each number is represented by a single perforation. In this case it is only nry to rearrange the extensions on the cams shown in Fig. 11 so that an index point in the 5 position on the card will be effective in deressing, for example, the A and B switch evers in Fig. 10 which will give an entering impulse in the 7 osition. The cam extensions for the ot er index points can also be arranged to effect set ups correspondingto any selected characters.

While the invention finds particular utility in transposin record readin s of one type into readings o another t pe, t e invention in its broad aspect is not imited to uses in direct connection with a perforated record, but the device may be utilized in accounting machines and the like generally or in other places where a conversion from a given reading into a correlated reading of a different type is desired.
