anoentoz Rei'ssued Oct. 4, I932 UNITED STA ES PATENT OFFICE i UEARLES OAMiPBELL, OF LONDON, ENGLAND, ASSIGNOR TO THE TAB'ULATING MACHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION OF NEW JERSEY TOTAL TAKING DEVICE Original No. 1,681,152, dated August 14, 1928, Serial No. 82,933, filed January 22, 1926, and in Great Britain February 4, 1925. Application for reissue filed March 27, 1929. Serial No. 350,419.

This invention pertains to recordcontrolled tabulating machines, being an improvement on the machine disclosed in Canadian Patent N 0; 247,815, March 17, 1925, issued to F. M. Carroll, and copending United States application Serial No. 607,847, filed December 19, 1922, by the same inventor, now Patout No. 1,87 5,849;granted Sept. 6, 1932. p

One function of that machine is to accumu- 1 late in two accumulators statistical data from a single field of perforated record cards, and to-print minor, or subtotals and major, or granchtotals from the two accumulators, under the automatic control of group perforationsin the cards. The same amounts are added in two accumulators, one handling.

minor totals and the other major totals.

When a subgroup control designation changes, a total is taken from the subtotal accumulator and that. accumulator is cleared or zeroizetl. The taking of a minor total does not affect the major total accumulator, which continues to add all amounts, regardless of minor group changes, until a major group designation changes, whereupon-a major total is taken and the major accumulator cleared, or reset. I

' Whenever changesoii major and minor group deslgnations occur simultaneously, the machlne prints elther the'mmor- 01' maj or total', but does not print bothtotals, and the principal object of the present invention is to provide improved devices which will enable the machine to print both minor and major totals whenever the minor and major group control designations change at the same time.

Briefly; this result is brought about by first printingthe minor total and then, if a major group has changed, causing the ma' chine to perform an extra revolution during which the major total is printed. Each accumulator is reset while its total is being taken.

Fig. 2 is a side view'of a portion of the other side of the machine, showing the mechanism of my invention as applied to the machine.

Fig. 3 is a plan View of the mechanism shown in Fig. 2.

Fig. 4 is a wiring diagram of the .electric circuits pertaining to my invention.

Provision is made for taking major and minor totals from the same records cards. The upper shaft 249 (Fig. 1) drives the major total accumulator, and the lower shaft 250 drives the minor total accumulator.

The accumulators are arranged in two banks, the upper accumulators being designated generally 253 and the lower accumulators being designated generally as 254.

Located above the accumulators is the printing drum carried on. shaft 161. The drum carries a number of type levers 162, one row of type levers being provided for each column on the card, and the number of the type'levers about the drum periphery corresponding to the index point perforations in the card column. These type levers, when engaged by the controllin hook members 163, cause the type to be tirown upwardly to print on the record sheet on the platen.

To control. the operation of the type levers 162 for listing items, call-magnets 165 are provided with individual armatures which control and elevate call-wires 166 which extend upwardly and control the printing devices.

Extending downwardly from the printer control mechanism are call-wires 240, each of which actuates an accumulator element through a member 266-to add onthat element the amount printed by the type bars to which,

that accumulator element is correlated.

" it will be sufiicient to know that the group control devices comprise upper and lower sets of contact brushes which simultaneously 1 sense the group control perforations of two successive cards. If the perforations are different in the two cards it means that a change of group has occurred, whereupon the total taking mechanism is brought into action, as will appear.

When a total is to be taken the total clutch magnet 323 is energized and causes vertical shaft 315. The armature 326 is urged downwardly (away from the magnet 908) by a spring 920. When the magnet 908 is energized the clutch 328 is engaged, therby coupling shaft 315 so as to drive a shaft 329 through the skew gearing shown in Fig. 2. When the magnet 908 is deenergized the armature 326 will be moved downwards by compression springs 920, whereby a clutch 330 will be engaged andcause the rotation of a shaft 331.

It may be explained that'the so-called total clutch controlled by the total clutch magnet, is a clutch of the one revolution type permitting shaft 315 normally to drive the selected shaft 329 or 331 one revolution only, although, of course, if the magnet 323 is reenergized at the proper times, the shaft 315' may perform more than one successive driv ing operation.

Beneath the pre-selecting magnet 903 is pivoted an armature 905 (Figs. 2 and 3) normally held in its lower position by a spring 921 and having a forked end which embraces e3 cam-shaft 950 tomake onerevolution, but

a groove in a double dog-clutch member 940 splined to a vertical shaft 941 mounted to rotate in suitable upper and lower bearing plates. This shaft has secured to it at its lower end a gear-wheel 942 in mesh with an idler 952 which is in mesh with a gear-wheel 962 secured to the lower end of the shaft 315, the gear ratio being 1: 1.

The shaft 941 also carries two gear- wheels 943 and 944 provided on their hubs with clutch teeth capable of being engaged by the clutch teeth of the member 940. These wheels 943 and 944 are normally free to rotate upon the shaft 941, and are clutched thereto by the engagement therewith of the clutch member 940, the wheel 943 being so clutched when the magnet 903 is deenergized and the wheel 944 when the magnet is energized, as will be readily understood; 1

A vertical cam-shaft 950 is mounted in I bearings'adjacent'the shaft 941, and has-secured to it two gear-wheels 943a and 944a i mesh with the wheels 943 and 944, respec Thus when the magnet 903 is deenergized, one revolution of the shaft 315 will cause the to hereinafter.

when the magnet 903 is energized the camshaft will only turn through one-half a revolution.

The shaft 950 carries a cam 950a of in- 'sulating material having one high point which engages and closes momentarily a pair of normally open contacts 478 to be referred Another pair of normally open contacts 907 are provided which are closed when the magnet 903 is energized by a rod fixed to and extending upwardly from the armature 905.

A third pair of contacts 910 are provided which are closed momentarily, by a cam 909 secured to the shaft 331, just prior to the end of the rotation of the shaft 331. p

The parts just described with reference to Figs. 2 and 3 operate to determine whether a sub-total only, or a sub-total followed by a grand total, shall be taken as will hereinafter he described.

1 The details of the total taking mechanism and its operation are fully explained in the above patent and application, and it will be suflicient for the present purpose to know that shaft 329 is caused to make one revolution when a major total is to be taken, and shaft 331 must make one revolution when a minor total is taken. 'The total taking operations carried out by shafts 329 and 331 include the resetting of the accumulators.

In the diagram (Fig. 4) brushes 480 are the tabulating brushes; upper and lower brushes 144 and 1145 are the group control brushes for minor groups, while upper and lower brushes 144a and 145a are for major group control. 503 and 503a are the minor and major group control magnets, respectively. 482 is the plug board by means of which desired circuit connections are made;

Magnets 503" may be plugged to lower brushes 145 by means of plugs 501 insertable in sockets connected to these brushes and located on plug board 482. These magnets may be plugged to upper brushes 144 through sockets 504 and plugs 505. As usual each column of automatic control has a magnet connected in series between its upper and lower brushes.' The magnet circuits extend as follows: from left side of the line through normally closed contacts 156, through wire 457, stop relay contacts 456 to common junction 463, thence through contacts 119' closed .as long as cards are on the drum, to common junction 47 6, cam contacts 454 and wire 479 to common lower brush 480. The brush 480 supplies current for the lower brushes and 145d so that thecircuit is. continued automatic control are handled-ina similar 1 and each pair is provided with a plug 511 which may be inserted in-a socket 512 in line 513. Ordinarily only one plug 511 is inserted, this one being chosen to place all the contacts 510 which are involved in minor automatic control in series with line 513. The contacts 510a which are involved in major automatic control are similarly plugged in series with a line 519. When operating under major and minor control also the switch 520 should be'open.

The contacts 510 now control a relay 515 serving to energize this relay whenever successive cards agree in their minor group perforations. The=circuits for this relayextends from the left side of .the line to common junction 463aspreviously traced, thence through switch 461, line 514, contacts 510 and inserted plug 511 to socket 512, thence through line 513 and relay 515 wire 516 tocommon junction 444, wire 517 and cam contacts 445 to the right side of the line. The relay 521 is similarly controlled by the major control contacts 510a.

So long as the machine is running and successive cards correspond so far as their group J designations are, concerned, both relays 521 and 515 will be energized. When a change in either a minor or major group occurs, one or the other of these magnets 521, 515 will be deenergized.

It is the relay circuit marked 523 of these two relays 515 and 521 which maintains the energization of the card feed clutch magnet 95. Consequently, after the circuit 523 is broken by either relay, the card feed clutch magnet will become deenergized at the proper time in the c cle and subsequently a minor or major tota will be taken, depending upon the energization of the magnets 908, 903, as will be explained.

The card feed clutch. circuit after the ma-- chine is once in operation extends from the left side of the line through normally closed contacts 156, wire 457, stop relay contacts 456, wire 458, cam contacts 455, wire 526 to common junction 459, 'thence through relay armature 460 of clutch magnet 95 to common junction point 452 and through card feed clutch magnet 95 to the, ri ht side of the line. Contacts 455 are normalfy' closed but open temporarily toward the end of each machi e. cycle. They therefore tend to deenergizecard feed clutch 95 and interrupt card feed at the end of each cycle. It is the object of the automatic control system to prevent this in the absence of a group'change. The contacts 455 are therefore shunted by the circuit 523, previously referred to, and controlled by relays 515 and 521. The shunt extendsfrom one side of contacts 455, wires 526 and 525 to contacts of relay .521, thence through circuit 523 and contacts of relay.515 to wires 524 and 514 to switch 461 thence to junction point 463 to stop contacts 456 and Wire 458 to the other side of contacts 455. As long asthis shunt circuit makes, which is the case Whenever relays 515 and 521 are both energized or, in other Words, when successive cards agreein group control perforations, the opening of contacts 455 at the end of the cycle is ineffective to deenergize card feed clutch magnet 95 B0 and card feed continues. When either relay 515 or 521 fails to be energized the shunt around contacts-455 fails to be established and the opening of. the contacts deenergizes card feed clutch magnet 95 and interrupts card feed incidentally forcing a total taking operation.

The -manner .in which it is determined. Whether a sub-total only, or a sub-total and a grand total, shall be printed will first be described. a 7

It should be explained that a sub-total is always required when a grand total is taken, whether the sub-group perforations change or not. For example, there may be two sucs cessive main groups representing two railways A and B. Each main group will usually comprise several sub-groups each relating, it may be, to a commodity such as coal or oil If the last-sub-group of main group A is f I coal and the first sub-group of main group B is oil, then the sub-group and main group perforations will change simultaneously. If the last sub-group of A is coal and the first sub-group 0 group perforations will not change. But a sub-group total of As coal must be taken, and V subgroup accumulator cleared. before the achine re-starts to tabulate Bs cards, otherwise As coal will be added to Bs next 3 sub-total.

Consequently, whenever the machine stops as a result of a change of group perforations, whether sub-group or main group or both, a

sub-total must be printed, to be followed by a grand total only 1f the main group perforations havephanged.

Reverting now to Figs. 2 and 3, it will be noted that the springs 920 normally hold the clutch-sleeve 327'in its, lower .position to f clutch the sub-group accumulator shaft-331' to. the resetting shaft 315. Only when the magnet 908pis energized is the clutch-sleeve raised by armature .326 to clutch the mam grbup accumulatorshaft 329 to the shaft 315. .1

Consequently it is necessary to energize the magnet 908 (when a grand totalvis" to be printed) at the end of one revolution of the shaft 315 and to provide for a second revolu tion of the latter. If no grand total is to be B is also coal, then the subprinted the magnet 908 is not energized and the shaft 315 need only make one revolution. When a change occurs in the sub-group perforations only, the magnet 515 (Fig.4) is deenergized and consequently the card-feed is stopped as previously described and cams,

known for convenience as E cams, function to cause the total-taking and resettlng shaft 315 to rotate, as isfully described in the above mentioned patent and application. As the main group pe forations have not changed, the magnet 52 is energized and attracts an armature 900 (F i 'g.'4) thereby opening a cir- I cuit AB in which is placed the winding of ready stated to take a grand total) is in a circuit C D containing the contacts 907 which are closed only when the magnet 903 is energized. Consequently the magnet 908 will not be energized, the sleeve 327 will remain in its lower position and only a sub-total will be taken.\ Just prior to the end of the single revolution of the shafts the cam 909 V closes the contacts 910 in the circuit C-D,

but as the contacts 907 remain open the magnet 908 remains nevertheless deenergizcd.

The cam 950a will close the contacts 47 Sat the end of the single revolution thereby reenergi'zing the card feed clutch-magnet and stopping the action of the E cams, as previously described, and the machine will continue on the next sub-group of cards. It will be noted that only one total taking-and resettin cycle has been performed.

hould the main group perforations change, but not the sub-group perforations, the magnet 521 will be deenergized (stopping the card-feed as previously explained) and the armature 900 will not be attracted. There will therefore be a circuit from A through cam contacts 9.01 (closed just priorto the stoppage of the card-feed) contacts 900, relay 902, grand total preselecting magnet 903 to B, this circuit'bein'g maintained by the closure of contacts 904 (prior to the stoppage 66 of the card-feed) and armature of relay 902.

The energized magnet 903 will raise its armature 905, closing the contacts 907 and throwing the clutch-member 940 into engagement with the gear-wheel 944. The sleeve. 327 being still in its lower position and the shaft 331 in gear with the shaft/315, the ensuing rotation of the latter will bring about a taking of a sub-total, as before. At the end of this rotation, however, the cam-shaft 950 will have made only a half-revolution, since the gear-wheels 944, 944a have a 2:1 ratio. Consequently, the contacts 478 will still be open. v

But the contacts'910 will be closed at the end of the revolution of the shaft 315'as before. The contacts 907 being closed, the cir" cuit CD through the winding of the grandtotal controlling magnet 908 will be completed, thus raising'the clutch-sleeve 327 and placing the grand-total accumulator shaft 329in gear with the shaft 315; this circuit CD being held closed (in spite of the reopening of contacts 910) by a holding relay 912, as will be apparent from Fig.4. Since the contacts 478 are still open, the E cams. will still function and a second revolutionof the shaft 315 will occur, thus taking a grand total. At the end of this secondrevolution the cam 950a will close the contacts 478 momentarily and thereby re-energize the cardfeed clutch magnet 95, thus starting a new tabulating operation on the cards of the next main group and stopping theaction of the E cams.

The cam-contacts 911 will thereupon open, thus deenergizing the magnet 908 and the relay 912, and the armature 326 will cease to be attracted. Consequently the spring 920 will return the'clutch-sleeve 327 to its lower .position, thus disengaging the grand-totalaccumulator and placing the sub-total accumulatorin gear with the shaft 315 in readiness for the next sub-total taking operation.

Further, assoon as the card-feed is resumed, the cam contacts 904 will open, thus deenergizing the holding relay 902 and the pie-selecting magnet 903, the armature 905 will be returned to normal by its spring 921 and the clutch-member 940 will move. out of engagement with the gear wheel 944 and reengage with the gear wheel 943. All. the

parts are therefore returned to their original position in readiness for the taking of the next sub-total.

. It will be apparent that if the sub-group perforations change at the same time as the main-group perforations the sequence of operations will be thesame as has been described fora change of main-groupperforations only, since a change of sub-group perforations does not, alter the position of the clutch-sleeve 327-that is to say, a sub-total will first be taken and afterwards a grand total, followed bya return of all the parts to normal. t -Iclaim: j
