Application filed September23, 1927. Serial No. 222,468;

The invention concerns accounting machines and has for its principal obJect the provision of mechanism for adaptlng a machine operating according to one system of mathematical progression to another system and to furthermore provide simple and novel mechanism for this purpose necessitating fewer and less radical changes in thecontrol and data receiving devices than have heretofor been required. An equally important object of the invention is to provide such mechanism of univversal application capable ofadapting each data receiving unit-to a single denominational order regardless of whether the increment of progression is greater or less than that for which the controls andreceiving devices are normally designed. For example the usual. accounting machine normally operates according to a decimal system and may be modi fied to operate according to fractions in certain orders provided the fractional denominators are less than ten. If it is desired to operate in certain orders according to fractions whose denominators are greater than ten V8,: rious expcdiencies'have been resorted to, such as using several entering units for thesingle fractional order. It is often very convenient to adapt one denominational order to twelve for handling the English monetary system or inches and feet and owing to the importance of this fraction in accounting machine practice it will be selected to illustrate the method of practicing the invention. 7

' Another object of'the invention is to provide mechanism for adaptingan accounting machine normally operating'according to a decimal system to operate according to frac- .tions' in certain orders without ntroducing 'lost motion connections.

Another object of the invention isto provide mechanism for record controlled raccounting machines to permit record cards having normally spaced index point positions to control machine operation in such manner as they would if the index point positions were spaced closer together on the cards, that is to substantially contract the index point s acing with respect to machine operation.

The corresponding printing type have the same'spacing on a'type bar and the type bar and card are move chronously so that as the'index point posi- When the analyzing mechanism: encounters an index point it controls devices for arrest ing the motion of the type bar bearingthe type corresponding to the index polnt in printing position. Now if instead of ten index point positions the card is provided with twelve spaced as'before and the type bar is provided withtwelve type spaced closer together on the bar so that they pass through printing position in the same time as the ten formerly did, it is obvious that the analysis of the card and the movement of the type bar. no longer agree. The contracting feature of the invention provides for maintaining synchronous motion between the card feed and the type bar and compensating for the in- I crease in the length of the analyzing opera tion due to the extra index points.

- Another object ofthe invention is to provide mechanism for record controlled accounting machines to -permit record cards :havmg normally spaced index points to control machine operation in such manner as they would if the index points were spaced further apart on the cards, that is to substant-lally expand the index point spacing -with respect tomachine operation. This is substantially the reverse of the contractingoperation.- For example, only eight index point positions might be used on a card 001- Y umn and eight corresponding. type located on atype bar covering the same space that ten normally covered. To maintain synchronous motion between the card and typebar inthis case the increase of type. spacing on thebar must be compensated. f A

Another object of the invention is'to provide for rearrangement of the index points on a controlling record for entry into'ithe accounting mechanism of the machine.

11, 10, 9, 8,7, 6, 5, 4, 3, 2, 1, 0. This transposition is provided for in the present invention.

Another object of the invention is to provide translating mechanism for" effecting the above translations consisting of a reading-in commutator cooperating with the analyzing mechanism to effect setups from which the translated data may be entered into the accounting mechanism.

AnOtherobJect of the invention is to provide setup mechanism for the above translation consisting of a commutator with brushes shiftable transversely thereof.

Another object of the invention is to provide translating mechanism for the above translation in which each shiftable brush is provided with an individual shifting magnet.

Another object of the invention is to provide translating mechanism for the above translations in which entries are received from a controlling card during one machine cycle and the translated data are entered into the accounting mechanism during a subsequent'machine cycle.

The invention will be described, by. way of example, in'connection with a specific form of record controlled printing tabulator. The tabulator is controlled by record cards on which numerical data may be represented by index points or perforations placed in any one of ten differentially located index point positions in each card column, a single index point in a column representing a particular digit, according to its location. The cards are fed with a continuous motion one each machine cycle, beneath analyzing brushes of which there is one for each card column, so

that the brushes search the index point positions successively. The driving mechanism of the adding devices and the driving mechanism of the printing devices operate synchronously with the card feed. A magnet is connected to each analyzing brush for con: trolling one denominational order of the adding mechanism and an operating pulse through this magnet results in coupling the adding device to its driving mechanism, the coupling persisting until a predetermined point in the machine cycle when it is automatically released. The pulses from the analyzing brush then momentarily energize the magnet in accordance with the'location of the index points and effect entry of the digits digit represented by the location of the perforation on the card in printing position. Both the printing and adding mechanisms are thus controlled by current impulses differentially timed during the machine cycles.

According to what is at present believed to be the preferred form of the invention the contraction, expansion or transposition, as

the case may be, is efi'ected through an auxiliary mechanism interposed between the analyzing brush and the adding or printing magnet. As a card is fed beneath the analyzin brushes the current pulses resulting from in ex points, instead of acting directly upon the adding or printing magnets to enter the data, act upon the intermediate auxiliary mechanism to effect setups corresponding to the locations of the index points on the card.

During the following machine cycle after the card is entirely clear of the analyzing mechanism the set up is reconverted into a timed current impulse for operating the adding or printing magnet. The auxiliary mechanism, owever, has provisions for retiming the impulses so that they occur in the proper order and with the proper timing to operate the adding and printing mechanism according to the required expansion, contraction or transposition.

. I The intermediate auxiliary mechanism. of

which one is provided for each card column, may consist generally of two commutator devices, one of which will hereinafter be re ferred toas the reading-in commutator and the other as the reading-out commutator. The reading-in commutator rotates synchronously with the card feed and has a series of contacts on its periphery arranged in groups equal in number to the active index point positions on the card. The groups are spaced to engage brushes riding on the commutator surface as the analyzing brush passes the several index point positions on the card and the commutator contacts are electrically connected to the analyzing brush. When the latter encounters a perforation a combination of circuits is closed through the particular group of commutator contacts then under the commutator brushes and these combinations are different for each index point.

- The reading-out commutator is rotated synchronously with the driving mechanisms of the adding and printing devices. In the present case it has been assumed that these mechanisms operate synchronously with the card feedas they ordinarily would in machines of this type'but, of course, this is not essential and they might have a different type of movement altogether. The readingout commutator is provided with a plurality of brushes shiftable transversely of its surface, each of. which may selectively engage one of two circumferential rows of contacts on the commutator surface. The brushes are shifted by individual magnets connected in l the circuits extending through the reading-in commutator brushes and the analyzing brush, from which it will be understood thata certain combination of brushes are shifted for each index point encountered by the analyzing brush. The circumferential rows of contacts on the reading-out commutator are likewise arranged in transverse groups equal in number to the different characters which might be entered into the adding and printing mechanisms. These transverse groups i are arranged to complete circuits through the shiftable brushes and the adding and printing magnets at certain times in the machine cycle according to the particular combinations of brushes which have been shifted. Obviously the contact groups may becarranged to initiate impulses timed as desired with respect to the machine cycle and the required expansions, contraction and transpositions are thus provided for.

The invention may be most clearly understood from the following detailed description which should be read in connection with the accompanying drawings in which the same reference numerals refer to the same parts throughout the several views and in which:

The invention is shown in Fig. 14 as a plied to a Wellknown type of tabulator fully described in the copending application of Daly and Page, ruary 5, 1925 (now Patent No. 1,762,145, issued June 10, 1930). The tabulator is represented diagrammatically and its circuit dia- Ser1alNo. 6980, filed Febgram and general operation will be explained volved in tabulating and listing operations are driven by the tabulating motor TM while the total taking mechanism and the printing? devices in total printin operations are driven by the reset motor Rfi. Before starting a tabulating operation the machine must be driven through a reset cycle to clear the accumulators of any data which mi 'ht remain in them from a previous tabulating operation and also to prepare the circuits of the tabulating motor for operation. The reset cycle is started by depressing the reset key R closing a circuitthrough the reset motor RM from one side of the main line 21 through resetmotor RM, reset clutch magnet 22, contacts 23 and normally closed listing contacts L--2 to binding post 12 in the other side of the main line 26. Immediately after starting the cam contactsP-1 close shortcircuiting the reset clutch magnet 22 to permit the reset clutch to disengage at the end of the cycle,

and the reset motor itself is stopped at the end of'the cycle by the opening of these contacts. This reset cycle momentarily closes andthen opens the lower contacts P--3 there;

by'energizing motor control relay 84 in seriesv with its stick magnet 91. The stick magnet prepares an additional circuit throu h cam are closed, the tabuing motor to binding post 16, thence through the card feed-clutch magnet 25 and start key contacts ST, motor relay contacts 86, through stop key contacts S to bindingpost 9 and through upper contacts P+3 closed except lating motor may be started by depressing the.

I during reset operations, to binding post 12 '84 to open the in the other side of the line 26. The tabulating motor TM and the card feed clutch magnet remain in operation through their various circuits, which need not be described in detail, as long as the contacts86 of the motor control relay 84 remain closed.

. The card feed clutch magnet 25 when energized causes engagement of the card feed clutch which through suitable picker mecha- 'nism indicated at 27 causes the cards 28 in the ma azine of the machine to feed one at a time beneath the upper analyzing brushes 30 and the lower analyzing brushes 31, one

card feeding beneath the upper brushes during one card cycle and beneath the lower tion. These contacts are normally open but are closed whenever their controlling mag nets 36 are energized and when closed remaln so until after the contacts 0-1 have opened and closed during the machine cycle The upper brushes 3O cooperate w1th contact blocks 37 which are connected to soclrets 38 The lower brushes 31 through similar 3 contact blocks 39 are connected to sockets 40.

It will be understood that although only two upper and two lower brushes are shown in the drawings, any number of them to operate on any number of card columns, the usual commerc al machine containing 45 upper and 45 lower brushes. Certain of the card columns are chosen for group control data and the group control magnets 36 are connected in series through the sockets 38 and 40 with the corresponding upper and lower brushes. As long as the control perforations in the control columns of the cards under the upper and lower brushes during a card cycle agree, the magnets 36 are energized at some time during the cycle closing their contacts and establishing a shunt about cam contacts O1. The machine thereupon remains in operation for another card cycle. As soon as the control perforations in the-cards under the upper and lower brushes fail to agree, indicating the end of a card group the control magnets 36 fail to energize, control contacts 35 remain .open andthe opening of cam contacts.

thence through

41 and 42 to lower card lever contacts LG, closed as-long as cards are passing the lower brushes, thence through wire 43 to cam contacts T'2 and T3 and through wire 44 to the lower brushes 31. The cam contacts T 2 and T-3 open and close to permit energization of the lower brushes only when the data can ing portion of the card is'passing the lower rushes. As the cards passthe lower brushes their index perforations permit the lower brushes 31 to instantaneously engage their cooperating contact blocks 39 to continue the brush circuits to the sockets which may be plugged to the usual adding and printin devices of the machine. The left hand rush 39' is shown so plugged to a counter magnet 164 for controlling it in the usual manner according to a decimal system.- The differentially timed impulses resulting from-the index points serve to energize magnet 164' at differential times during the cycle to operatethe adding and printing mechanism of the machine in a manner well understood.- a

In the present case the right hand upper brush 30 is shown connected with translating mechanism according to the present invention to read a. certain card column' for twelfths instead of tenths and to modify the effect of the entering impulses. The reason for using an upper instead of a lower analyzing brush for this purpose will appear later. The general scheme of operation of this translating mechanism will be explained in connection with a system for adding twclfths on certain accumulators and printin elements 1n amachlne operating normal y according to the decimal system.

Referring to Fig. 5 a controlling card of the Hollerith type is shown at H provided with index point positions in columns for the digits from nine to zero with two extraindex point positions after the zero, designated as ten and eleven.

brushes coverlthe lndex point positions'in of the machine is shown in Fig. 8 and this bar rises synchronously with the passa e of the card past the analyzing brushes to ring its 6, 5, etc. A normal type but The analyzing type opposite the printing line 45 as the cor respondlng index point positions on the card are passing the analyzing brushes. If the adding mechanism operates in a similar manner except that the impulse results in clutching the counter elements to their driving shaft for a definite time in the cycle corresponding to the index point which causes the impulse. Referring again to Fig. 5, if it is desired to operate the machine in certain columns according to twelfths instead of tenths, the two upper index point positions .10 and 11 may be used but this results in lengthening the analyzing portion of the cy cle and also in displacing the 10 and 11 index points from their logical progressive positions on the card; that is, instead of being analyzed prior to-the 9 index point position they are analyzed after the zero index point position. In Fig. 9 a type bar 50 is shown with twelve type designated from zero to eleven spaced within the same spacing as the ten type on the normal type bar 48 in Fig. 8, and in order to make the machine standard as far as possible, it is necessary that the type bar 50 move synchronously with the other decimal type bars 48 of the machine. To

operate this type bar (see Fig. 5) it is necessary not only to compress the longer analyzing cycle into one of normal length but also to rearrange the order of the index points as indicated at T. If this is done, the printing magnet 51 in Fig. 9 will be operated to trip the latch 52 permitting it to engage the several teeth 53 on the type bar to arrest the type on this bar in the proper position for printing.

The general manner in which this compressing and transposition is efiected may be understood from Fig.14. This right hand upper analyzingbrush 30 controls the twelfths printing and counter magnets through intermediate translating mechanism'which in the present case consists of a reading-in commutator 55 and two pails of reading-out

commutators

56 and 57. The analyzing brush is connected to abrush 46 making contact with a continuous conducting strip 47 on the reading-in commutator. The reading-in commutator is driven in synchronism with the card feed'making only one half a revolution, however, for each card feeding cycle. Two sets of

brushes

59 and 60 cooperate with a group of contacts 61 on the commutator surface. The contacts cover substantially half of the periphery and coact with the brushes 59 during one card feeding or machine cycle and with the brushes 60 during the following machine cycle. The brushes 59 control magnets 62 and the contacts 61 are arranged so that a certain group of them' is under the brushes when acertam index point is under the analyzing brush thereby energizing the magnets 62 in different combinations for each index point on the cards. The brushes 60control similar magnets 63 during alternate cycles in an identical manner. The two pairs of reading-out.

commutators

56 and 57 are operative during alternate cycles and are provided with shiftable brushes which are shifted under control of the magnets '62 cooperating with the brushes of the commutators 56 and magnets 63 cooperating with brushes of commutators 57. The shiftable brushes cooperate with contacts on the surface of reading-out commutator to retime and rearrange the entering impulses from which the counter magnet 64- is energized at the desired time to enter the data which is recorded onthe'cards. The data is read from the card during one cycle and the magnets 62 energized to shift the brushes on the commutators 56 and during the following cycle when the succeeding card is under the analyzing brushes the commutators56 cooperate with the brushes as shifted to energize the counter magnet 64 at the proper time during the cycle. During thisfollowing cycle the contacts 61 cooperate with the brushes 60 to energize the magnets 63 for shifting the brushes on the commutators 57 and the data from this card is entered into the counter magnet during the next following cycle. The operation of contracting and transposing data entries may be best understood from Fig. 2 of the drawings in which the reading-in and reading-out commutators are shown in development. The contacts 61 on the readin -in commutator surface are ar j ranged in our circumferential rows indicat-f ed at A, B, C, and D, each row cooperating with an individual brush 59. The contacts are also arranged in transverse rows desig-. nated as 9, 8, 7, 6,5, 4, 3, 2, 1,0, 10 and 11, each transverse row except the one designated 0 containing one or more contacts. Themotion of the commutator is such that the row marked 9 is under the brushes 59 when the 9 index point position on the card is passing the analyzing brush and so on. Whenever the analyzing brush encounters a perforation a certain combination of the magnets 62 is energized to shift corresponding brushes 65 on the reading-out commutators 56.

The reading-out commutators are likewise each provided with four circumferential rows of contacts 66 arranged also in transverse rows designated as 11, 10, 9, 8, 7, etc. Each brush 65 normally cooperates with one circumferential row of contacts 66 but when its Y magnet 62 is energized is shifted to cooperate with an adjacent row. The upper brush 65 of the upper commutator 56 is connected 9 is connected in accordance with an index point one of the transverse rows of contacts 66 simultaneouscorresponding 1y bridges the two pairs of brushes at a given point in the cycle resulting in an entering impulse through the counter magnet. The timing and order of this entering impulse depends, of course, on the arrangement of contacts 66 in transverse rows and obviously the order and timing can be arranged in any desired manner. It will be noted that the transverse rows of contacts 66 are spaced closer together than the transverse rows of contacts 61 which accounts for the contracting feature. The arrangement of the contacts in rows provides also for the transposition of the 10, 11 impulses to their proper place in the series.

The operation will be clearer from a specific example. Assume that an index point occurs in the 6 index point position of a card under the upper brush. As this index point encounters the analyzing brush a circuit will be completed through the brush 46 and conducting strip 47 to the contacts 61 in the 6 row, that is in the A and D circumferential rows. Owing to the synchronous movement of the card and commutator, the 6 rowis at this time under the brushes 59 and the circuit is extended in two branches, one leading to the magnet 62 designated A and the otherleading to the magnet 62 designated D thereby energizing these magnets'to shift their brushes 65 on the reading-out commutators 56. After the shifting is complete the upper brush 65 cooperates with the second circumferential row on the upper commutator 56 and the lower brush 65 on the lower commutator cooperates with the lower circumferential row of contacts 66 on this commutator. As a 6 is to be entered into the accounting and printing mechanism, indicating in the present case six twelfths, it will be noted that no circuit can be completed through the contacts 66 until the transverse row 6 comes under the shiftable brushes 65..

At this time each pair of brushes 65 will be bridged simultaneously by the connected contacts in the row and the resulting'ope'r ating impulse o erates the counter and printing magnets.

trol the shiftable brushes 65 to initiate an entering impulse at the proper time in the following card cycle. It'will be understood that the pulses initiated from index-points in the right hand column of the card shown in Fig. 5 have thus been rearranged and spaced closer together as indicated by the

points

11, 10, 9., 8, 7, 6, 5, etc. designated T.

ther index points on the rec- 0rd card operate in a similar manner to con-' trains 7 0, one gear of which is freely mounted on the counter shaft 71. The counter shaft rotates during adding cycles but the gear trains 70 do not rotate until they are positively clutched to the shaft. The clutching mechanism comprises clutch teeth on the side of the gear of train 70 which is mounted onthe shaft and sleeve members 72 which are splined to the shaft but shiftable in and out of engagement with the clutch teeth on the gear. The clutching engagement is effected by momentary energi'zation of the counter magnet 64. This magnet is provided with a pivoted armature 73 which carries a latch for pivoted lever 74. This lever has one end extending into an annular groove in the clutch sleeve 72 and its other end spring-pressed by one of the spring contacts urging it to clutching position, from which it is normally maintained, however, by the latch on armature structure 7 3. When the magnet 64 is energized to attract its armature the latch is released permitting the lever 74 under action of the spring contact 75 to force the clutch sleeve 72 into engagement with the conforms ,to the differential timing of the impulse which energized magnet 64.

The translator mechanisms indicated generally at 80 of which'one is provided for each card column in which a translation is to be. I

made are driven 'insynchron'ism with the counter shaft71 througha gear train 81 having a gear ratio to cause the reading-in and reading-out commutators tomake one revolution for each two card cycles or every two revolutions of counter shaft 71. The operating elements of the translators 80 are driven from gears 82 fixed to a shaft 83 which is driven by the gear train 81. It may be assumed that the lower counter wheel 69 is arranged to indicate twelfths while the others are arranged to indicate tenths. The driving connection between the twelfths counter' wheel 69 and theshaft. 71 is similar to that for driving the other counter wheels in that it comprises a constantly meshed gear train and .a similar clutching element. Either the gear train or the gear teeth for this twelfths unit must be arranged so that the counter wheel may rotate in increments of twelfths instead of tenths- The complete driving cycles of all the counter elements coincide. however, and the twelve increments of movement of-the lower counter wheel may occur. ".within the same elapsed time as the ten more-- ments of'movement of the, other counter wheels: The difierent timing of the entering 5 impulses for 'thejtw'elfths unit are spaced within the normal entering cycle as just ex type bar carrying ten type with-normal spac ing is provided with nine notches 85 to permit arresting the type bar in any of the nine 35 positions represented by the type one to nine. I In Fig. 9 the type bar 50 carries twelve type from zero to eleven which-are so spaced on the bar as to cover the same distance as the ten type on the bar 58 do, and the bar is provided 2 with eleven notches 53 to permit arresting the motion of thetype bar with any of the I type from one to eleven in printing position upon the line 45. The cyclical operation of the printing is notdisturbed and the type -bars i8 and 50, rise together to bring their type opposite the printing line. The type bar 48, however, may be controlled directly from an analyzing brush while the type bar 50 in order to compensate for its contracted type spacing must be controlled through a translating device, the entering impulses being retimed' and rearranged'as j u'st explained;

The printing magnet 51 is controlled from a. the counter magnet '64 during listing operations "(see Fig. Whenever the magnet 64 is energized during a tabulating operation it efi'ects closure ofcontacts 88 thereby completinga circuit through the printing magnet 51; the closure of this circuit being substantially simultaneous with theentering impulse through the counter magnet so that the same data ma be entered into the adding units and printed.

9 At the end'of a card group as previously I i stated, the tabulating mechanism ceases op-' eration anda total may thereafter bev taken either automatically or by the pressing of reset button R. It will be recalled that the translating mechanism is set up during one card cycle and the reading, as modified, en-

ter'ed into the accounting mechanism during the following card cycle; This is the reason that the upper instead of the lower analyzing brushes have been used to control the readgroup is followed in the present machine by a totaling cycle and if it were attempted to control the translating mechanism from the lower brushes the data from the last card of each group would remain in the translating mechanism over the total taking operation and would be entered into the accounting mechanisms during the first tabulating cycle of the following group. Controlling the w from the upper brushes,,howe ver, the

; entry injgin mechanism. The last card cycle of 'a data from the last card is entered into the translator when the last card is passing the upper brushes and is read out as the last card is passing the lower brushes during the last tabulating cycle of the group.

The total taking clrcuit through theiprinting magnet 51 extends through contacts 90 whose operation is clearer from Fig. 4. This figure shows total taking mechanism associated with the counters which is fully described in the copending application of Lake Serial No. 639,193 filed May 5, 1923. A gear 93 constantly meshes with the train 7 0 to ro- -tate whenever the counter wheeli69 rotates.

Fast to this gcarv93 is a stepped cam 92 havcording to the tens system of progression, it would be provided with nine steps corresponding to the digits from one to nine while if operating according to the twelfths system of progression, it would be provided with eleven steps corresponding with the numbers from one to eleven. Durlng the total taking operation the type bars move uniformly as before through printing position and syn chronously'with this movement a shaft 95 'rocks. Fast to this shaft is a frame 96 on which is pivoted a contact finger 97 carrying a set screw 98 at its end, cooperating with the 1 steps of cam 92. The finger 98 is held by a spring 99 in the position shown in'the drawings against the frame 96 and it is provided with an arcuate rear extension 100 which is energized during the total taking cycle, from a brush 101 fixed on the machine frame and sliding on the arcuate surface of 100. The

frame 96 carries a brush 102 which when the V finger 97 is in normal position against the frame is just clear of the arcuate extension 100. The frame and finger rock downward as the type bars rise until the set screw 98 encounters one of the ste s' on cam 92 whereupon the movement of nger 97 is arrested and the continuing motion of frame 96 causes the brush 162 to engage the arcuate extension 100 and thus initiate an entering impulse for the printing magnet. The position of the cam 92 alwa s corresponds to the number indicated bythe adding wheel 69and the impulse initiated 'is therefore 'diiferentially timed during the cycle according to the numbers standing on the accumulator so that the I proper type 18 selected for printing.

The structural details of the translating mechanism are shown in Figs. 1, (land 7'. In Fig. 1 a complete translating unit is Shawn consisting of one reading-in commutator 55 and two sets-of reading-out commutatorsefi.

operating magnets

62 and 63 are mounted on a common base plate 165'. The

commutatorsare all geared together and to the gear 82am shaft 83 (see also Fig. 3) so that as the counting and printing mechanism e0 mg steps equal in number to the characters thatare to be printed, that is, if operating ac- I again energized.

performs two cycles, thecommutators each make one revolution. The

commutators

56 and 57 with their brush shifting and other operating mechanisms are identical and only one set will be described. The construction of the reading-out commutators will be most clearly understood from Figs. 6 and? of which Fig. 7 shows the parts in normal po- 110 on the pivoted supporting structure of:

the armature 111 of shifting magnet 63. When the magnet 63 is deenergized the lever 108 is held in the position shown in Fig. 7 by the extension 110 overlying the extension 109. When the magnet is energized to attract its armature as shown in Fig. 6 the ex-- tension 110 moves ofi the extension 109 and permits the spring 113 to shift the lever 108 bringing the brush 65 into the position shown in Fig. 6. The commutator 57 is cut away for substantially half its periphery and this cut away portion is opposite the brushes 65 during that card cycle in which shifting impulses through the magnet 63 occur. Refer ring to Fig. 1 itwill be noted that the cut away portions of the reading-in

commutators

56 and 57 are displaced 180 degrees "with respect to their shiftable brushes so that the brushes of one set of commutators may be freely set up during one machine cycle while the brushes of the other are reading-out an entry; The brushes'65 either in their shifted or unshifted position ride in grooves 112 in the raised portion of the reading-out commutators. These grooves serve to insulate the ends of the brushes from each other and the contacts 66 are placed at the bottom of them. Shortly after the brushes 65 leave the grooves 112 any of them which have been shifted to-take'a reading are shifted back to the normal position in.Fig.,7. A pivoted arm 115 is provided with a pin 116 which extends into the path of a cam 117 mounted on the face of the driving gear of the commutator. This cam encountering the pin rocks the arm 115 whose end thereupon restores the lever 108 to normal position allowing the extension 110 on the supporting structure of armature 111 to again engage the projection 109 on' lever 108 and hold it in this normal position until the magnet 62 is The invention thus far has been explained in connection with a device for adapting a twelve point progressive system to a ten point machine but it is obvious that it 515 equally well adapted to other systems. In Fi s. 10 to 13 a translating mechanism is indicatedfor operating in accordance with an eight point progressive system for han dling eights fractions. In this case the counter mechanism and the printing mechanism for handling eights moves synchronously with the usual tensmechanisms performing a complete cycle in increments of eights. In this case if the usual card indicated at H in Fig. 11 is utilized for indicating eighths only seven index points from zero to seven will be utilized and it will be neces sary to expand this portion of the analyzing cycle to cover a complete normal analyzing cycle as indicated. Here the spacing of the entering impulses must be expanded instead of contracted. In Figs. 12 and 13 a normal type bar 48 hearing ten type is aligned with a type bar 51 hearing eight type from zero to seven covering the same'space longitudinally of the bar as the ten type on bar 48.

The type bars as before rise synchronously and the retiming of the entering impulses according to Fig. 11 serve to compensate the different spacing on the eights type bar. In the case of the accumulating mechanism the drive for the eights counter wheel must, of

course, be adjusted to provide for increments of eight-hs instead of tenths.

The developments of the reading-in and reading-out 'commutators for the eighths transformation is illustrated in Fig. 10. The reading-in commutator 55" is identical with the reading-in commutator 55 except that the transverse rows of contacts corresponding to'the index points 9, 8, 10 and 11 have been omitted leaving only the rows from one to seven corresponding to index point positions in which perforations may be placed. -The reading-out commutators 56 rotate as before in synchronism with the counter driving mechanism and the printing mechanism but as in this case entering impulses may occur only in seven different positions only seven rows of transverse contacts 65' are provided, these seven rows being evenly spaced within the same space that the eleven rows occupied on the twelfths readingout commutator's. Aside from this different spacing of the contacts on the reading-out commutators the operation of the machine is identical with that explained in connection with the twelfths system. An index point on a controlling record in the column representing eighths result in shifting of certain brushes 65' and the contacts 66 are arranged in transverse rows so that the entering impulses are retimed as required to cover the complete normal entering and analyzing cycle.

The invention has now been described in connection with several embodiments to illustrate generally its distinctive features. It is to be, understood, however, that these embodiments have been selected merely with a view to illustrating the utility of the device and are not to be construed in a limiting sense. The. transpositions, that is the rearranging of the timing of the pulses resulting from index points, is of general application. If desired tWo spaces in the middle part of the card for example the index points 5 and 6 might be left blank and these index points displaced to the 11 and 12 positions and transposed back to their proper position for entry by the transposing mechanism. The invention has also been described specifically with respect to mathematical progressions but it is not limited to the use of numbers as the operation of the machine itself involves the progression necessary for the operation of the device which may be applied to alphabetical or other characters.
