4 Claims.

This invention relates to perforated card controlled machines and more particularly to a de-V vice for making electrical connections between various parts of the machine.

5 In the well known I- Iollerith tabulator, connections are made between various brushes adapted to sense the several columns in a perforated record card and the several orders of different accumulators so that any `column on a card may be caused to control any order of any accumulator. Also, when printing is being effected in suchmachines any order of anaccumulator may be connected to any column of type so that the printing will be done in a desired posi-` tion on the report sheet. Or if listing is being done directly from the card any column on the card may be connected to control any column of type to cause printing to be done in the desired columnon the report. y

It is the usual practice to connect each brus toy a plug socket on a plug board and connect each accumulator and each column of type tov other plug sockets'on the board. Connections are then made by plugging across these various sockets asdesired. y

According to my invention, instead of plug sockets interconnected by loose plug wires, terminal contacts are provided to take the place of j vbrushes are tobeconnected to the accumulator-3 40 andv printing'magnets so that data may be taken from any of the columns on the data cards'and caused to control any of the orders ofv the ac? cumulators or columns. vof printing elements by being variously connected to the magnets whichv control the accumulating and printing. In other Words, the present invention does away with the necessity of using plug wires to inter :onnect the sensing brushes and accumulating and printing 50 magnets and provides a set of settable contact slides tof accomplish the same result. These slides may be set manually, if desired, or they may be set undercontrol of the report card or,

if desired, they may be set under control of the card and then particular ones may be reset man- (ol. css-92) ually to differ from `the set up effected by the card. y

In other words, a card may have been punched to control the making of a particular form of" report and in special instances it may be desired 5 to vary certain items in the report. These slight variations may be -eiected by first setting the various slides under control of the card and then changing the particular ones desired to elect the particular type of report required. 10

It is also common with vthese machines to bring about the taking of a total at the end of one group of cards and before accumulating commences under control of the next group. This totaling may be done automatically when the 15 machine detects a change from one group to the next. The feeding of -cards at this time automatically ceases and the machine performs totaling operations, clearing the accumulators. if set to do so and then resuming accumulating or 20 accumulating and listing operations under control of the next group of cards. In some instances, the groups of cards are divided into major and minor groups as, for instance, whenl reports have been made covering the several 25 months and the various days of the months. In such cases, the groups of` cards may be divided into minor groups covering the days and major groups covering/the months. All the cards for one day are placed together followed by the group 30 of vcards for the next day and so on to the end of the month. Also all of the cards for the several days of one month are placed ahead of cards for the succeeding month. At the end of a group'of cards for a particular day the ma- 35 Y chine is automatically caused to print a. total of `*the data relating to that days transactions and .to then commence operation in connection with the., dat

` y l whe next day. At the end of the l'as't'dylof he month, there is a change in the 40 major group as well as in the minor group and the total forthe day is printed followed by the total for all of the days for that month. After this the machine commences analyzing cards for the rst day of the next month. i i

The setting of the machine. to operate to take totals of major and minor groups is also eecte'd by the setting of slides under control of the report or' form card. At the end yof each minor group total the accumulator may be caused to clear so that each days total will be separate from each other day or the machine may be set totake progressive or accumulative totals so that each days total will be included with the totals of the preceding days of the month. The connections to control this are also eected by the setting of the slides either manually or under control of the form report card. In other words, connections may be made with respect to each of the accumulators in the machine to cause them to clear after the printing of minor totals or after the printing of major totals. Also the accumulator which controls the printing of major totals will, of course, be set to accumulate data taken from all of the cards of all of the minor groups included in the major group without any clearing operations until after the printing of the major total.

Also this accumulator may be set to accumulate progressive major totals so that when the last major total is printed it will include Aall preceding major totals or, in other words, will constitute a grand total of all of the major totals.

Referring to the drawings:

Only so much of the machine is shown diagrammatically as will be necessary to an understanding of the present invention and the manner in which it is used in connection with well known tabulating machines.

In Fig. 8a of the drawings, a stack of perforated data cards I is shown in position ready to be fed one at a. time by the card picker 2 to the feed rollers 3. Each card is fed downwardly between the upper sensing brushes 4 and cooperating contact blocks 5 and then between the'lower sensingV brushes 6 and corresponding contact blocks "I, As the successive index point positions of a column of one card are fed past the lower brushes 6, the corresponding index point positions of t e next succeeding card are being fed past the up r sensing brushes 4. The closing of electric circuits through the lo\ er brushes 8 serves to control the machine to\ ccumulate and print data contained on the card.

on to the lower brushes so that its data may be 'Ihe upper brushes 4 by sensing acontrol designation ascertain whether a card being analyzed belongs vto the same group to which the card under the brushes 6 belongs. If the card under the brushes 4 belongs to the same group as the card under .the lower brushes, it is permitted to pass the stop key 32.

taken and accumulated and printed. If the card under the upperv brushes belongs to a diiferent group, or in other words, if the card under the lower brushes is the last of apa ticular group the feeding of cards ceases mom ntarily yhile the machine passes into a totaling cycle of operations during which the total of the preyious group is printed. The accumulator in whiclrthe total was accumulated may then be cleared if desired after which the card feeding is resumed. When this takes place the card which was under the upper brushes and brought about the taking of the total is fed to the lower brushes and its data is taken and accumulated and also printed, if the machine is set for such operations.

The machine is operated by an electric motor 8 driving a shaft 9 through a belt I0. A clutch II is adapted to connect a shaft I2 to the normally running shaft 9 in order to effect the driving of the cam shaft I3 and the feed rollers 3 and card picker 2. The motor 8 is shown Within dotted lines in the upper part of the diagram along with its windings I4. The source of electric current for operating the machine is represented at I5 and may be connected to the lines I6, I'I by a switch I8. `The operation of the machine may be started by depression of a start key I9. This will close contacts 20 and complete a circuit through the motor 8 as follows: from the positive side of the line I6 through the winding of the motor 8, through relay coil 2I through the card feed clutch coils 22, relay coil 23. contacts 20 now closed, to the point 24, contacts 25a normally closed, stop button contacts 26 also normally closed to the point 21, contacts 28 which are closed at this time and to the negative side of the line I 1.

The energization of the relay coil 23 closes contacts 23a so that the operator may now release the start key I9 and the circuit through the motor and the card feed clutch relay 22 will continue through the contacts 23a., through the contacts 30 which are closed by the upper card lever 3| as soon as the rst card fed reaches the position of this lever as indicated below the feed rollers 3; from here, the current continues to the point 24, contacts 25a, contacts 26, point 2l, contacts 28 to the other side of the line. As

`long as cards continue to pass through the ma- .chine they will keep the contacts 30 closed and the. machine will continue to operate. Should the cards fail to feed the contacts 30 will be permitted to open and this will break the circuit through the card feed clutch magnet 22 and the motor-8.

The machine may also be stopped at any time while cards are being fed, by the depression of This also breaks the circuit through the motor and the cardfeed clutch.

, The stopping of the operation of themotor 8 differs from that in the card under the lower brushes 6. As disclosed in U. S. Patent #1,762,145, to G. F. Daly and R. E. Page, relay coil 25 is controlled through a plurality of contacts 33. These contacts are adapted to be controlled by the comparison of the card under the lower brushes with the card under the upper brushes.

At certain times in the cycle of operation of the machine, the closing of a contact is adapted to feed current' to/ these contacts 33 and if they are found t0 be/closed the machine continues to feed .cards and accumulate data.

If, on the other hand, any one of these contacts has failed to close, the circuit will not be made at the proper time and the feeding of cards will stop and the machine will be caused to take a total.

The circuit through the contacts 33 and the manner in which they are controlled will be brought out in greater detail in the description of the attachment or device which is subject matter of the present invention.

The contacts 33 `are connected to plug sockets 34. A plugv socket is also normally provided .in thejplug board of this machine'so that a plug connection may be vmade from socket 35 to any of the sockets l.34 and in this way eliminating from the circuit, all of the contacts 33 to the right of the socket 34 which is thus connected to socket 35. For instance, if group controlling is being effected through only one column on the card, it will only be necessary to use one of the contacts 33, namely, the one farthest to the left in Fig. 8a. In this instance, the socket 34 farthest to the left will be connected by plugging to the socket 35 and a circuit from line 36 will pass through the contact 33 to the first plug socket'34. across vthe A.plug line to the plug socket 35 and so forth. If, on

the other hand, controlling Vis being. effected.

through three columns of data on the cards, then three of the contacts 33 Will be employed and The plugging will be from the third socket 34 to the socket 35. In this instance, current from the line 36 will pass across the several contacts 33 if they are all closed to the third socket 34 and then to the socket 35, and so forth. If all of the ten contacts 33 arey used for group controlling then the tenth socket 34 will be plugged to the socket 35 and itwill be necessary for` all ten of the contacts 33 to be closed in order to effect continuation of the operation of the machine; failure of any one of the ten contacts 33 to be closed by similar data in the corresponding column of the cards will cause the circuit to remain open and the operation of the machine will change from accumulating to totaling.

The group control contacts 33 may be split by r 34, 35, contact slides are moved to any of several possible positions to eiect the desired connections between the sockets 34 and 35. In the carrying out of the present invention, the connccting slides and contacts may be applied to the machine as an attachment and permanently connect-ed to the plug sockets 34, 35; or the device may be built into the machine as an integral part thereof and connections to the contacts 33 may be made permanently, eliminating the sockets 34, 35.

vplurality of parallel bars .411' connected by means of a'lwuV4 A 46 tooneof the same plug board as are the sockets 34, 35. The A sockets 31, 38 make it possible to connect .the other parts of the machine to any of the brushes 4, 6, so that the data contained in various columns on the cards may be caused to control any .accumulator or any order in an accumulatorvand any column of vtype in the printing section of the machine. Sockets 39, 40 (Fig. 8c) also in the plug board are associated with the individual columns of the accumulators and type and the connections from sockets 31, 38 to the sockets 39, 40 are made in various combinations as desired.

According to the present invention, these various connections are also effected through the setting of contact slides. Here, again, the device may be connected to the accumulators by plug connections in sockets 39, 40,.orthe device may be built into the machine as stated' and the sockets and plug board omitted, the wires from the interconnecting slides lto the accumulators and type control magnets being direct.

Other plugging sockets 4|, 42 normally provided in the plug board for the purpose of connecting any ofthe brushes or columns on a card to the group control device may also be omitted and the connections made ,directlyA to the control slides. For convenience, in the present instance, the control slides are shown as conf nected through the sockets 4|,.42. Referring now to Fig. 1the casing or frame 43 is shown as having brackets 44 supporting ka each of which, is.

of Fig. 8a.

upper brush contact 4blocks .A

plurality of slides 41 mounted ...ie by side are arranged below the bars '45.'and efffending transversely with respectthereto. Each bar ,41 carries a plurality of contact brushes`48 adapted to engage the bars 45. The slides 4'1 are .adapted to be moved to the right or left to bring the brushes 48 into engagement with different bars 45. The brushes 48 are spaced along the -slide 41 at a distance corresponding to the distance between ten of the bars 45. slide 41 is provided with similar brushes 48a, each pair of brushes 48, 48a being electrically interconnected through rivets 49 byV which they are` attached to the slide 41. The brushes 48a are adapted to slide upon contact strips 50 carried by an insulating block 5I. K

The length of the contact strips'50 is such thatv the slide 41 may be moved its full distance to the right or left without disengaging the brushes 48a from their respective strips 5D.v This limit The lower edge of each` of movement of the slide 41 permits the engagement of brushes 48 over a range of ten of the bars 45. Thus, each group of ten bars 45 may be connected through its brush 48 and corresponding brush 48a to a Contact strip 50 which is thus common to the ten bars 45. It will thusy be seen that by adjustment of the slide 41 a particular contact strip 50 may be connected to any one of the corresponding group of ten sensing brushes 4 through the bars 45. In the lower portion of the casing a bracket 44a is shown supporting a plurality of bars 45a similar to the bars 45. Each bar 45a is connected by a wire 46a to one of the brush contact blocks 1 associated with the lower perforation sensing brushes 6.

Integral with thesliding bar 4l is another slide 41a. This slide carries contact brushes 52, 52a, interconnected by rivets 49a. The brushes 52 are adapted to cooperate with the bars .45a while the brushes 52a are adapted to cooperate with contact strips 56a carried on an insulating block 5ta.

The slide 41a is moved to the right or left with the slide 41 so that when the latter is adjusted to bring its brushes 48 into cooperation with certain of the bars 45, the brushes 52 will r be adjusted to cooperate with corresponding lower bars 45a. In other words, when a brush 48 is adjusted to cooperate with a particular one of the several upper perforation sensing brushes 4, a brush 52 will be adjusted to cooperate with the 'corresponding lower perforation sensing brush 6. Between the upper and lower insulating blocks 5|,.5la, are slides 53 provided with oppositely disposed contact brushes 54, 55, each separately connected by a rivet 56 to the slide 53. The vertically alined rivets 56 of a pair of opposite brushes 54 and 55 have their enlarged rear ends or bases seated in alined recesses internally formed in the two layers which make up slide 53. As seated in these recesses, the alined rivets have their bases spaced apart and out of engagement so that the opposite brushes 54 and 55 remain insulated from each other by slide 53, as ndicated in Figs. 1 and 8b. The brushes 54 are adapted to cooperate with contact strips 50 while the brushes 55 are adapted to cooperate with contact strips 50a.

The slide 53 is adjustable to the right or left to bring one of its sets of brushes 54, 55 into cooperation with corresponding upper and lower contact strips 50, 50a. There are ve of the contact strips 50 and corresponding strips 50a and therefore ve sets of brushes 54, 55. In any given position of the slide 53, one only of the sets of brushes 54, 55 will cooperate With opposite strips 50, 50a. The slide 53 may be termed the tens order slide and the slide 41 the'units order slide.

Assuming that the device is to be used in connection with tabulating machines adapted to be controlled by perforated cards having 45 columns of data, there will be 45 of the bars 45 and 45a. The bar farthest to the right may be used in connection with card counting and the` bar farthest to the left may be a dummy to receive unused- Wires 46, 46a. There will also be ve of the contact strips 50 and ve strips 50a. The bars 45 will be grouped in four groups of ten each and ya, fth group of five; the bars 45a being similarly grouped.

Assuming that the upper and-lower cardsensing brushes v4, 6 are numbered 1 to 45, the barsV 45 and 45a may be similarly numbered beginning at the left from one to forty-five with an extra bar at each end. If it is desired to connect a particular column of card sensing brushes to -effect group control the slides 41, 41a and the slide l53 will be adjusted accordingly: for instance, assuming that contro] is to be eiiected through column 26 on the card, corresponding brushes 4, 6, i. e. those reading that column, will be connected through bars 45, 45a and the slides, to connect with the group control mechanism, by

moving slide 53 so that its brushes 54, 55 will cooperate with the strips 55, 50d of the 20 order.

. The slide 53 is shown in such position in Fig. l.

ing to the cardsensing brushes of the 6th, 16th, 4

26th and 36th columns. 'Ihe slides 41, 41a in Fig. 1 are illustrated as adjusted to such position. Thus it will be seen that the bar 45 of the 26th column is connected through brush 48, 48a to the 3rd contact strip 50 then through brushes 54, 55, to the third one of the lower contact strips 50, then through brushes 52a, 52 to the bar 45a which is connected by its particular wire 46a. to cooperate with the lower card sensing brush which cooperates with the 26th column on the data card. It will be understood that there will be as many slides 41, 41a and intermediate slides 53 as there are possible control columns. In other Words, it is common to provide possibility to effect group control in connection with ten columns of perforations on the card. There may then be ten sets of the slides and contacts, etc. shown in Fig. 1. These slides may be adjusted so that they may be variously connected with the ten columns on the card. If some only of the ten columns are to be employed for group control, the corresponding number of settings may be effected and the rest of the slides 41, 41a and 53 left in their normal or inoperative positions.

In Fig. 8b of the wiring diagram ltwo sets of the contact slides disclosed in Fig. 1 are shown connected to control the operation of the tabulating machine represented by the wiring of Fig. 8a. Here two of the upper card sensing brush contact blocks 5 are connected through wires 46 to the bars 45'and several of the contact bars 1 associated with the lower sensing brushes 6 are connected through wires 46a to the lower bars 45a. The insulating blocks 5I, 5la are provided with contact strips 51, 51a. adapted to cooperate with brushes 58, 58a, brush 58 being electrically connected through a common strip 59 to all of the brushes 54, while brush 58a is electrically connected through a common strip 59a to all of the brushes 55. The strip 51 is connected by a wire 60 to one of the points or plug sockets 4| and the contact strip 51a is connected by a wire 60a to the opposite point or plug 42. Two of these sets of slides and contacts are thus shown connected to two sets of plugs 4I, 42.

These plug points are interconnected by a magnet coil 6| in series with a pair of contacts 62. Each of the magnets 6I is associated with one of the sets of contacts 33 in Fig. 8a and is adapted when energized to close its set of contacts 33. It is understood that when any of these sets of contacts is closed during a card reading cycle of the machine, it will remain closed after the magnet 6| has become deenergized and is mechanically released later in the cycle after the controlling circuit has determined whether the machine shall continue to feed cards or take a. total. It is also understood that the magnet 6| upon being energized opens the corresponding contacts 62 thus breaking the circuit through the magnet after the corresponding contacts 33 have been closed and locked in such position.

'I'he manner in which the setting of the contacts 33 serves to control the operation of the machine to take totals after each group of cards has been analyzed is disclosed in the patent heretofore referred to. The manner in which these contacts are connected to take a total on a change in a minor group and also in a major group is fully disclosed in the aforementioned patent. It will be described sufficiently here,

however, to show the manner in which it coop-` erates with the present invention.

It will be understood that after the machine vhas been started by the depression of thestart key and after the preliminary setting up of the machine has taken place, the major control relay contacts 63 and the minor control relay contacts 64 will both have dropped to open the upper contacts which are shown as closed in Fig. 8a and will close the lower contacts which are shown here as open. 'Ihe opening ofthe upper contacts 63 and the closing of the lower ones are effected by the energization of the relay coil 63a and the opening of the upper and closing of the lower contacts 64 are eiected by the energization of relay coil 64a. y,

Assuming then, that these two coils are enel'- gized and are holding their lower contacts closed,

current will pass from the line I6 through lower contacts 64coil 64a, contacts CI, contacts-L3,"

wire 65 to the other side of the line I1. After the cards have been analyzed to ascertain whether the group numbers on the upper and lower cards are the same the cam CI will permit the CI contacts to open and if the groupnumbers on the two cards are the same. the `current through the coil 64a will pass around the CI contactsv through the wire 36, the first contact 33, ',(asfsluni-4 ing that we are group controlling on b ut one column) then through wire 66 to a bar 61, -b'rush 68 carried by a slide 69 then to the common strip 10, brush 1I, contact strip 12,'wire 13, bar 14, brush 15, contact strip 16, brush 11, contact 18, wire 19 to the connection point 35, card lever contacts 80, which are closed at this time as long as cards are passing through the machine and back to the line I1.

By thus maintaining the coil 64a energized the lower contact 64 will remain closed and the machine will continue to feed and analyze cards and to accumulate and print the data taken therefrom. If the group control numbers on the i two cards were different, the rst group control contact 33 would not have been closed as current would not have been fed simultaneously through the corresponding upper and lower brushes 4 and 6 and through the coil 6I (Fig. 8b) which serves to close the control contacts 33. Deenergization of coil 64a permits the conta ts 64 to return to their normal position with th; upper set closed. Current will then flow from line I6 through, upper contacts 64 to relay coil 25, wire 65 tothe otherside of theline. The energization of coil 25 opens the relay contacts 25a so that the current now flowing through the driving motor 8- and the card feed clutch 22 will fail and feeding of cards will stop.

Deenergization of the card feed clutch magnet 22 permits contacts 22a, to close. of the card cycle, contacts LI `close momentarily.

This introduces a total cycle during which the machine prints a total or totals from the accumulator or accumulators which were used for accumulating the data taken from the group of cards which has now completed its passage through the machine.

the reset motor then continues through contacts PI, relay contacts 86,' contacts L2 which are closed throughout a totaling or reset cycle back to the line I1. Near the end of the totaling cycle, contacts PI open and the reset motor RM stops. Also the contacts LP1 close near/the end f the totaling cycle and a circuit is se up frcgi the line I6 through contacts LP1, coil 64a., c tacts CI, L3 and wire 65 to the other side of th line. The relay magnet 64a will now open the pper set .ofr contacts 64 and close the lower set. This will'bijeak the circuit through coil 25 permitting contacts 25a to close. The upper contacts 63 op'en before thebeginning of the accumulating cyclestand the lower contacts l63 close by energization` offmajor control magnet 63a. -When the brush 15,"c ontact' strip 16, brush 11, bar 18, wire 19, .contacts 80, to the line I1.

36, contacts 25a, 26 to point 21, contacts 28 baci:l to the line I1. This causes resumption of card feeding and accumulating and listing operations.

Thus far, we have assumed that we were controlling the machine 4on but one column of the card. If controlling is to be effected from three columns on the card, it will be necessary to use three of the sets of contacts 33. The three coly umns of the card will be connected through` the slides 51, 51a to control the corresponding three relay magnets 6I. Also the minor control -slide 69 will be moved to the right as viewed in Fig. 8a so that the brush will engage the bar 61 designated 3. The brush 68 will now be out of engage ment with all of its bars 61 but the brush 1I will continue in engagement with strip 12. Now when the contacts CI are opened during the testing tima-current will pass through lower contacts 64, relay'magnet 64a, wire 36, the three sets of contacts 33 farthest to the left, then to the third bar 61, brush 90, strip 10, brush 1I, contact strip 12, wire 13, bar 14, brush 15, strip 16, brush 11, strip 18 to point 35, contacts 80 back to the right side of the line. If any one of the three sets of contacts 33 fails to close by reason of a dissimilarity in the columns being used to control, the circuit through relay 64a will be broken. Upper contact 64 will then close and relay coll 25 will become energized opening contacts 25a to stop the card feeding and the operating motor 8, and the totaling and reset or totaling cycle will be started.

AAssuming now that major and minor group control is tobe employed, each using three co1- umns to control, the slide 69 will be set so that the brush 90 will cooperate with the 3 bar 61 vand the major selector bar 9| will be moved to the right so that the brush 92 will engage the 6 contact bar 61. The `brush 15 will now be disengaged from the bar 14 but brush 11 will continue iii-contact with strip 18. 'I'he first, second. and third sets of contacts v33 are now connected for minor controlling and the fourth, fth and sixth sets for major controlling.

The control relays 6I for these sets of contacts will be connected to the respective columns on the card by the manipulation of the appropriate six sets of slides 41, 41a. and 53. Now as long as the cards under the upper and lower brushes contain the same major and minor group numbers all of the contacts 33 in the control circuit will be closed so that current passing from the left side of the line for the minor control will pass through contacts 64, relay 64a, wire 36, thenl through the six sets of contacts 33 (including the major group) into the 6 bar 61,through brush 92, strip 16, brush 11, strip 18 to point 35,

contacts to the other side of the line l1. At the same time that, this minor test circuit operates the major test circuit through its contacts 33 will be caused to operat'e by opening of cam contacts L3 which takes place at the same time that contacts C| open. Current will then pass from the line I6, through lower contacts 63, holding relay 63a, wire 93, wire 94, contact strip 12, brush 1|, contact strip 10, brush 90 (set to the "3 bar), then by way of such 3 bar 61 across the fourth, fth and sixth sets of contacts 33, to the 6 bar 61, brush 92 (set to this point), contact strip 16, brush'11, strip 18 to point 35, contacts 80 to the line 1. Should a change in group number occur in the minor control column the minor control circuit will failpermitting lower contacts ,64 to open and upper contacts 64 to close, but

the major control testV circuitxwlll not be broken and the relay 63a will continue to hold the` lower contacts 63 closed. The machine will then perform one totaling cycle of operations. On the other hand, if a change occurs in the major group control number the major control circuit as well as the minor control circuit will open and the lower contacts 63, 64 will both open and upper contacts 63, 64 will both be closed. This will cause the machine to perform two cycles of resetting and totaling operations.

Toward the end of the iirst of these cycles,

contacts LP6 close for a short period and then reopen, but nothing happens at this time because contacts LP1 and lower contacts 64 are open. Immediately thereafter, contacts LP1 close completing the circuit through the relay coil 64a as previously described, causing the lower contacts 64 to be closed and the upper contact 64 to be opened. This does not deenergize relay coil 25 at this time because the upper contacts 63 are still closed. During the second resetting or totaling cycle, contacts LP6 kwill again close and a circuit will be closed from the line I6 to lower contact 64, contacts LP6, relay coil 63a, contacts L3, wire 65 back to the line|1. The energization' of relay 63a will close .the lower contacts 63 and open the upper ones. This breaks the circuit through relay coil 25 permitting contacts 25a to close. It may be pointed out here, that when relay coil 25 is energized coil 86a will also be energized to open the contacts 86. Thus, when lower contacts 64 are closed after the taking of major and minor totals the relay 86a continues to hold the contacts 86 open so that when, during that cycle, the contacts Pl are closed the current cannot pass through the contacts 86 and the relay 84 is permitted to remain energized. During the second resetting cycle, however, after the upper contacts 63 open to deenergize relay 25 the relay 86a will be deenergized at the same time and will close contacts 86 so that now when the contacts PI close the circuit will be shunted from the 'relay motor around the relay 84, permitting the contacts 84a to open. Then, when the contacts P| open, the circuit will be completely broken through the resetting motor RM. The closing of the contacts 25a will as has been pointed out nov( cause the operating motor 8 and card feeding clutch 22 to operate to resume card feeding and accumulating and listing operations.

The connecting of any of the columns on the card to the desired accumulators and orders thereof and also to the various columns of printing type is eiected by the adjustment of slides 95, 96 (Fig. 8b). Each of the bars 45a as we have seen is connected to one of the'lower sensing brush contact blocks 1. 'I'he adjustment of the sliding bar 96 will move the rst of five lower brushes 91 into cooperation with any one of the rst ten bars 45a. The second of these lower contact brushes 91 will be moved into cooperation with any one of the next ten bars 45a, etc. The five upper brushes 91a will continue to maintain contact with their respective contact strips 98. The movement of the tens sliding bar 95 on the other hand, determines which of its brushes 99 shall cooperate with one of the five contact strips 98. In Fig. 8b,the fourth of the several brushes 99 is shown as engaging the fourth contact strip 98. Thus, one of the columns ranging from 30-39 will be connected through the corresponding brushes 91a, 91 to one of the bars 45a. In the present instance, the units bar 96 is so adjusted that the several brushes 91 cooperate with the bars 45a of the 2nd, 12th, 22nd, 32nd, and 42nd columns so that the column 32 on the data card will be connectedthrough the corresponding sensing brush to the accumulator order to which the slide |00 is connected. The circuit, tracing it from the right side of the line, will be through contacts 28 (Fig. 8a) to point 21, contacts 26, 25a,'30, 89, line |0| to the device designated |02 as a whole, wire |03, common bar |04, sensing brushes 6, corresponding contact bar 1, wire 46a, to the corresponding one of the bars 45a, brushes 91, 91a, contact strip 98, brush 99, common contact strip |05 to brush |06, contact strip |01, wire |08 to point 39 (Fig. 8c) through the accumulator magnet |09, contacts ||0, back to the line-.|6.

The energization of relay |09 opens the contacts ||0 and closes the contacts in the well known manner. cThe energization of magnet |09 as is understood controls the particular order of the accumulator and is immediately deenergized by the opening of the contacts ||0. The closing of contacts on the other hand closes the listing circuit through ||2. The mechanism associated with ||2 for effecting printing when listing as well as when totaling is well known and need not be disclosed in detail here. If listing is not to be effected the contacts||3 serve to break the circuit through the listing magnet |2 but are closed during the resetting cycle or totaling.

In order to elect listing a switch is ordinarily provided to shunt the circuit across the' contacts ||3. According to the present invention the shunting of the circuit around the contacts ||3 is effected through a slide ||4 provided with contact brushes ||5 electrically connected to each other. Movement of the slide ||4 to the rght so that two of the brushes 5 will engage t e bars |6, ||1,will close the circuit around the c ntacts ||3. Thus, when contacts are closed urrent will pass from the line |6 to the common bar I I8, through contacts magnet I2, common bar ||9, wire |20, contacts |2|, wire |22, bar ||1, throughbrushes |5to'bar |6,wire |23, lower contacts P2 which are closed for printing, switch |24 back to the line l1. 'me bar H4 is also pro- 75 vided with a pair of brushes |25 which when the bar is moved one step to the right closes a circuit across the bars 26, |21. When the reset motor is energized the current passing through the coil 83 will close the contacts 83a so that current will pass from the line I6 through. these contacts,

-through brushes |25 to bar |21 through the zeroizing magnet |29, relay contacts |30 held open bv magnet v group change occurs,.and back to the line |1.

If resetting of the laccumulators is to be effected the slide ||4 is thus moved one step to the right. On the other hand, if it is not desired to reset the accumulators the slide ||4 will be moved twosteps to the right and the brushes |25 will'not bridge the gap between the bars |26, |21 but two of the brushes |3| will bridge bars |32, |33 so that current will be supplied to the printing magnet 2 as follows: from the line I6, through wire |34, bar |32, brushes |3|, bar |33, wire |35, common bar |35. stepped contacts |31, printing relay ||2, bar H9, contacts |2|, contacts ||3, which are closed during the resetting cycle, back to the other side of the line. The setting .of the slide ||4 two steps to the right to bridge the contactl bars |32, |33 does not bridge the bars ||6, ||1 so that while current is supplied to the printing magnet during resetting cycles no current will be shunted around the contacts ||3 during the accumulating cycles and vno listing will be eiected. As the bars |26, |21 are not bridged by the brushes |25 the zeroizing magnet |29 will not be Venergized and the accumulators will retain the values throughout successive total printing operations and thus produce progressive totals. If, progressive totals along with listing of the several items is to be effected the slide 4 will be moved three steps to the right, two of the brushes 3| will still bridge the bars |32, |33 and two of `the brushes l5 will now bridge the bars H6, |1.

The circuit through the printing magnets 2 will now be closed during successive card cycles of the machine for listing and the circuit for printing will take place during resetting cycles across the bars |32, |33.- For listing only the slide ||4 will be moved four steps to the right sothat the brushes |3| c lo not bridge the bars |32, |33 but two of the brushes ||5 will bridge the bars i6, l1 to close the circuit through the printing vmagnet |2 during listing cycles.

Each of the slides 95 is connected to a link |45 reaching forward'and provided with a depending pin |46 adapted to cooperate with a form card I4? carried by a movable frame |48. Each of the slides 96 on the other hand, passes around to the other side of the frame' |48 and is provided with a link |49 having a depending pin |50 also cooperating with the form card. As shown in Fig. la

the form card |41 is mounted directly over a perforated plate |5| integral with the carriage |48. The form card is adapted to be perforated so that the pins |45, |50 may reach through the card and into any of the perforations in the plate so that as the frame |48 is moved to the right, it will move the slides 95, 96. The frame |48 is provided with studs |52, |53 cooperating with slots |54 in plates |55 which in turn are provided with studs |56 adapted to slide laterally in slots |51 in the frame 43. l

Cams |58 mounted on a shaft |59 carried by the plates cooperate with the studs |52, |53 so that as the shaft is rotated, the cams will serve to raise or lower the frame |48. In this way, the form card |41 may be moved upwardly to coop- |3||a and which are .closed when a erate with the pins |46, |50 and may be lowered to disengage the pins. Also fixed to the shaft |59 is an arm |60 provided with a stud `|6| cooperating with a slot |62 in the side ofv frame 43. A crank |63 is provided for rotating the shaft |59.

The normal position of` the parts is shown in Fig. 3, the form frame 48 being at the left side of the machine and in raised position. Turning of the crank |63 clockwise to the position of Fig. 2 will, through the stud |6| cooperating with slot |62, cause .the plate |55 and frame |48 to be moved to the right as shown in'liig.v 2. Further rotation of the crank |63 fromthe position of Fig. 2 to that of Fig. l causes the lowering of the frame' |48 by the-cam |58. The form card is shown in Fig. 5. The card is divided into five elds designated l to 5 with perforations for con-y trolling accumulating in the five sets of accumulators. These elds are divided into upper and lower portions |64, |65. v Each upper eld is provided with eight perforation positions `in horizontal rows there being four such rows. In other words, there are eight columns of perforation positions with four positions to each column. The lower portion of the field 65 on thel other hand is provided with eight columns with nine perforation positions to a column. Each of the upper columns of' perforation positions corresponds with one of the slides and each of the lower columns corresponds with one of the slides 96. When the Vform card sin `position the link vBy punching all of the columns as desired, the

movement of the frame |48 to the right'will thus set lall of the slides 95, 96 and in this way effect the desired connections between all of the columns on the card and all of the columns in the accumulators andthe printing type. Each of the links |45, |49 is shown as having upward extensions |45ca, |49a so that after all of the slides have been set under controll of the orni card individual changes may be made by manually moving the links |45, |49 to any desired position. A setting of the slides 41, 41a(Figs. l and 8b) is effected through a link |49b and the setting of the slides 53 is eiected through a link |450. These links cooperate with the `ten columns-in the upper and lower portions |66, |61 near the left end of the form card |41 (Fig. 5), the slide 53 being controlled by the upper columns of `perforations in the portion |66Y of the `field and the slide 41, 41a beingI controlled by the lower perforations in th-e portion |61. Col'- umn ten would be selected by a 10 perforation in yiield |66 and no perforation in field |91y as the contacts 52 are normally on the l0 bar. Selection of field 20 would in like manner be eff'ected by a perforation in the 20 position in the eld |35, etc. The slides ||4 (Fig. 8c) are shown in detail in Fig. 6. These slides are provided with links |4a having pins |413 adapted to cooperate with the perforations in the field |68. There are five columns of these perforations with four perforation positions to a column. Each column willv be punched in accordance with the nature of the control desired in connection with the rive counters or sets of accumulators and will cause the respective slides M4 to be moved from the normal p sition of Fig. 8c to any one of the four positions described.

In Fig. 6 the slide ||4 is shown as having a brush |59 sliding over the bars 45a. This brush is not electrically connected to anything and serves only as a guide for the slide lill. Details of the slides 69, 9| are shown in Fig. '7. The two slides are mounted side by side and so only one of them shows in this view. The slide 9i is provided with a link 9|a adapted to cooperate with the column |19 which is farthest to the left on the form card of Fig. 5. The slide @9 on the other hand is connected by a link 59a to an offset pin 69h adapted to cooperate with the lower portion |1a of the same column of perforations on `the iorm card.

While the machine is in operation, the crank |63 may be left in the position of Fig. 2 or that of Fig. 1. After having used the machine under control of the form card the parts may be restored to their normal positions by turning the crank |63 clockwise to the position of Fig. 3. This not only restores the frame |48 to starting position but also through a restoring bar 1| carried by the carriage or frame |48'restores all of the slides to their normal positions. For this purpose, the links |45 and slides 96 are provided with projections |12, |13 reaching into the path of the restoring bar |1|. The bar thus engages these projections as the frame |48 is moved to the left and carries the slides along in this direction. In Fig. 1 the slides 41, 41a are restored by cooperation of the bar |1| withthe connectingI portion |14. The form cards |41 of Fig. 5

are provided with printed indications of the positions for punching and the punching is done according to the nature of the report to be made out on the machine under control of the perforated record cards. In this connection the operator wishing to connect the 33rd column of the perforated record cards to the units order of the 2nd accumulator in the machine will punch 33 in the 26th or units column of the second accumulator on the form card. In other Words, as shown in Fig. 5, the 26th column on the form card is punched in the tens iield on the line designated 39 and in the units field on the line designated 3.

In Fig. 9, a modified form card |41a is shown. This card may be made up of a very thick lower portion covered by a thin upper portion |411), the lower portion may be provided with perforations |410 in all of perforation positions and the upper portion will normally have no perforations. When it is desired to prepare the card to control the making of a particular kind of report the operator will use a pencil to puncture the covering |411) directly over the severalholes |410.
