17 Claims.

The present invention relates to improvements in tabulating machines, and more particularly refers to machines of the type disclosed in Letters Patent of the United States No. 1,822,594, issued September 8, 1931 to C. D. Lake.

Machines of the type disclosed in this patent are well known in the art and are adapted to analyze record cards having control points or perforations thereon. Such machines, after analyzing the control points, may print all or a part of the data on a suitable record material or they may print data from each card and the total of such data for each group by cards. They may accumulate the data from successive cards, printing the total accumulated from all of the cards, or from a particular group of cards. These machines are quite flexible and other similar combinations may be effected.

In the machines disclosed in the above mentioned patent, the group numbers as taken from the card directly control the printing mechanism of the machine to print the group number from the rst card of each group. After the first card of a group has been analyzed and the group numbers thereof printed, the machine proceeds successivelyto analyze the remainder of the cards in that group and upon a change of group designating numbers the tabulating machine automatically is brought to a stop and a total taking and resetting operation is initiated to print the total standing on the accumulator which total is the total data accumulated from the group, and to reset the totalizers to zero.

One object of the present invention is the provision for printing the group number from the first card of each group while suppressing the printing of the total data accumulated from said group until the total of said data has reached a predetermined amount.

Another object is the provision for printing the group number from the first card of each group and suppressing the resetting of the totalizers until a predetermined amount has been accumulated thereonA I Still another obect of the instant invention is the provision of means operated under the control nf the accumulator wheels to suppress reading the accumulator until the total standing thereon has reached a predetermined amount.

A further object is to suppress resetting the accumulator until the total standing thereon has reached a predetermined amount.

Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings; and the invention also constitutes certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the drawings:

Fig. 1 is a front view of the accumulator section of the machine showing a part of the reset mechanism.

Fig. 2 is a fragmentary view of a part of the accumulator wheels showing the relation of the control bail thereto.

Fig. 3 is a sectional view of the accumulator section of the machine.

Fig. 4 is a facsimile of the record prepared on the machine.

Fig. 5 is a sectional view of the printing section of the machine.

Fig. 6 is a facsimile of a record prepared on a tabulator not provided with our device; and

Fig. 7 is a conventional illustration of the circuit diagram.

General description In order to understand the significance of the instant invention as applied to a machine of the type disclosed in the above mentioned patent, it should be borne in mind that such machines are adapted to be controlled to make listing operation and tabulating operation. The machine is controlled for listing operation to print the individual items with the group numbers and then prints the totals of the items without printing the group numbers. When controlled for tabulating operations, the group numbers and totals only are printed. A facsimile of a record sheet prepared on a machine controlled as set forth above is illustrated in Fig. 6.

In certain organizations it is not desired to print the total of each group unless the total is equal to or greater than a predetermined amount. In this case the group number is printed when the rst card of each group is tabulated, but the total for the groups is not printed unless it equals or exceeds the predetermined amount. 'I'he machine will continue tabulating successive groups of cards, printing the group number of each group, until the amount accumulated equals or exceeds the predetermined amount, whereupon, the machine is automatically controlled to make a total printing and resetting operation during which the total is read from the accumulator, and printed in line with the last printed group number, and the totalizer then reset to zero. As an example tor illustrative purposes let it be assumed, that a machine embodying the present invention is to be used in a railroad freight office wherein records are made of freight shipments including, the stations from and to which each shipment isy made, the weight of each shipment and the revenue derived therefrom. Figure 4 is a facsimile of a record prepared on such a machine.

In this case the railroad does not wish to record the weight of, and revenue derived from individual or group shipments of less than, for instance, 2,000 pounds. However, it is desired to indicate the shipping point and destination of each group or shipment. By using our device on a tabulating machine, characters designating the stations for each group are printed, but the total revenue and the total weight for each group are not printed until the total accumulated weight equals 2,000 pounds or more.

Referring to Figure 6 it will be noted that the two left hand columns are marked Stations, From and To, the next column to the right is marked Revenue and the right hand column is marked Weight, In the station column marked From characters are printed indicating the station from which the shipment was made, and similar characters are printed in the station column marked To indicating the destination of the shipment. On the facsimile (Fig. 6) there are printed opposite the station designations for each group or shipment, the revenue and weight. For instance, on the first line a shipment was made from station 890 to station |23 weighing 567 pounds and from which shipment a revenue of $89.12 was received. The second line records a shipment from station 234 to station 561 comprising 1802 pounds of freight which brought the railroad a revenue of $46.90. Line 3 indicates that the next group of cards run through the tabulating machine represent a shipment of 1780 pounds from station |23 to station 456, the revenue therefor being $24.68. It will be noted that each of these shipments were less than 2,000 pounds.

Referring now to Figure 4, which represents a record sheet prepared on our improved tabu- Iating machine, it will be noted that the same station numbers are printed on the rst three lines in columns 1 and 2 as are set forth above. However, neither the revenue nor the weight of the rst shipment were printed on the rst line since the Weight was less than 2,000 pounds. These amounts are entered into the totalizers but since the total weight at the end of the group was less than 2,000 pounds the total printing was suppressed.

During the listing of the second group the total weight accumulated on the totalizer passed 2,000 pounds. At the next group change, therefore, under the control of the mechanism comprising the present invention, the weight and revenue totalizers are cleared and the totals standing thereon printed in the proper columns.

In case the Weights represented by two groups f of cards do not bring the total Weight to 2,000

pounds or more, the next group is accumulated, and as many additional groups as are necessary to bring the total Weight to 2,000 pounds.

The circuit diagram (Fig. 7) is substantially the same as that shown in the above mentioned Lake patent. During tabulating operations the machine is driven by a tabulating motor TM (Fig. 7) under the control of the usual cam controlled and relay controlled circuits indicated generally at I0. During reset operations the machine is driven by a reset motor RM4 under the control of a group of contacts and relays indicated generally at Il.

When the machine is operated by the tabulating machine motor TM, the usual tabulating cards bearing differentially arranged index points or perforations, are fed past sets of upper analyzing brushes UB and then, exactly one card cycle later the cards are fed past lower analyzing brushes LB.

As the perforated cards are fed past the lower brushes the perforations thereon permit instantaneous closing of circuits to energize accumulator magnets |2. The timed energization of these magnets control mechanism well known in the art, to enter data interpreted from the card onto the accumulator wheels.

The accumulator is of the typedisclosed in U. S. Patent No. 1,379,268 issued to C. D. Lake, May 24, 1921, and which includes gears l5 (Fig. 3), rotatably mounted on a reset shaft I6 suitably supported in the machine. These gears mesh with and are driven, under the control of the magnets I2, by gears |1 mounted on a shaft I8. An indicator Wheel |9, having indicia engraved, or otherwise suitably marked thereon, is secured to each of the accumulator gears |5 to enable the operator to read the data standing on the accumulator, directly therefrom through a convenient sight opening 20 in the casing 2|.

The printing mechanism (Fig. 5) is substantially the same as that fully disclosed in Lake Patent No. 1,822,594 and, described briefly, includes a plurality of type elements 22 slidably mounted in the enlarged upper end of a type carrier 23. The type carrier is guided near its upper and lower ends to permit vertical movement for the purpose of selecting the type elements 22 for operation.

To effect the vertical reciprocatory movement of the type carrier 23 on tabulating operations a cam 24, secured on a shaft 25, is provided with a cam groove 26 embracing an anti-friction roller 21 on an arm 28 pivoted on a shaft 29. An adjusting screw 30 carried by the arm 28 cooperates with one arm of a lever 36 fast on the shaft 29. A short link 31 connects an arm 38 also fast on the shaft 29 to a printer cross head 39. Guide bars 40 are provided to guide the cross head 39 in its vertical travel.

The configuration of the cam groove 26 is such that upon one rotation of the cam 24 it imparts to the arm 28, the lever 36. shaft 29 and the arm 38 an invariable excursion first clockwise and then counterclockwise to normal position.

This movement is communicated by the link 31 to the cross-head 39 imparting thereto a vertically reciprocatory movement.

The cross-head 39 is actuated on total printing operations by a cam 4| and a total shaft 42. This cam 4| cooperates with a roller on an arm 43 pivoted on the shaft 29. A projection on the arm 43 cooperates with an adjusting screw on the other arm of the lever 38. Thus, on total printing operations, the cam 4| acting through the arm 43 rocks the lever 36, shaft 29 and the arm 38 to impart to the printer cross-head 39 its regular excursion.

The type carriers 23 rest on spring held ngers |43 pivotally supported on projections |39 forming a part of the cross-head 39 so that the type carriers travel upwardly with the cross-head for the purpose of carrying the type elements 22 past a printing point on a platen 42 in synchronism with the passage of the card by the lower brushes LB (Fig. 7). Ii', as the card travels past the lower brushes, a control point comes into registry with one of the brushes the upward travel of the type carrier is arrested with the particular type 22 corresponding to the differential location of the control point on the card in printing position.

The device for arresting the upward movement of the type carriers 23 in synchronism with the passage of the card by the brushes LB and, on total printing operations, in accordance with the amount standing on the accumulator wheels includes a spring pressed stop pawl 44 (Fig. 5) normally held in ineffective position by a detent 45. Both the stop pawl 44 and the detent 45 are pivotally supported on a cross bar 46 suitably supported in the machine. A link 41 connects the detent with an armature 48 associated with a printer magnet 49. It is to be understood that there is a type carrier 23 and a printer magnet 49 for each denominational order of the accumu-lator.

When the printer magnet 49 is energized either under the control of a card or on total printing operations, under the control of the usual impulse emitter 50 (Fig. 7) controlled by the totalizers, it attracts the armature 48 (Fig. 5). This draws the link 41 toward the right (Fig. 5) rocking the detent 45 counterclockwise to release the stop paw] 44 which, under the inuence of its spring, immediately engages the proper one of a series of notches in the right hand edge of the type carriers 23 in order to stop the carrier in a position commensurate, on tabulating operations, with the position of the control point on the card, or, on total printing operations, in a position commensurate to the setting of the corresponding accumulator gear I5.

Group control It is well known in the art that machines of this type may be organized to automatically stop the listing or tabulating operation and to start a total printing operation when the control perforations on two successive cards do not agree. 'Ihe means for initiating such an automatic group control involves a group control circuit such as is disclosed in the above referred to Lake Patent No. 1,822,594, which circuit, described briefly includes magnets 5| and contacts 52 (Fig. 7) adapted to be plugged between the upper and lower brushes. The purpose of the contacts 52 is to open after the magnets 5| are energized in order to take the arc from the brushes. Energization of the magnets 5| closes corresponding contacts 53, thus establishing the so-called control circuit which extends serially through all contacts 53. This circuit is established in each card cycle so long as the control perforations on each two successive cards agree. So long as this control circuit is made the machine will continue uninterruptedly to tabulate the cards passing through the machine.

However, if one or more group control perforations do not agree on two successive cards,

the corresponding magnets 5| are not energized and their contacts 53 are not permitted to close. Thus the group control circuit is o-pen and at the end of the card cycle the machine is controlled to initiate a total printing operation, during which operation, the amount standing on the totalizer wheels I5 (Fig. 3) is read off from the wheels, set up on the type carriers 23 (Fig. 5) and printed. The totalizer is then reset to zero.

The machine may be controlled to proceed automatically from a tabulating cycle or operation into a total printing operation, and from a total printing operation into the tabulation of the next succeeding card group.

The mechanism whereby a total printing and resetting operation is initiated automatically will now be briefly described.

When one or more group control numbers or perforations on two successive cards do not agree and the corresponding contacts 53 remain open, as above set forth, a magnet 6|, known herein as the Group control magnet, becomes deenergized upon opening of test contacts 62 near the end of a tabulating operation. The magnet 6| is normally energized on tabulating operations, holding its armature 63 against the upper contact to maintain magnets 65 and 66 deenergized. So long as the magnet 65 is deenergized an operating circuit is maintained through the tabulating motor. This circuit extends through the tabulating motor TM, a start relay coil |60, the clutch coils 11, motor relay coil |6|, contacts |62 closed upon energization of coil |6| to form a holding circuit for said coil, upper card lever contacts |63, the contacts of coil 65, wire |64, the normally closed stop key contacts |65, cam contacts P3 to the other side of the line. This circuit maintains the tabulating machine motor TM running as long as cards are passing the upper card lever.

However, when a group change Occurs and the magnet 6| is deenergized, its armature 63 drops into contact with the lower contact energizing the magnets 64 and 65. The magnet 65, when energized, attracts its armature thus opening the circuit through the tabulating motor TM. This deenergizes clutch magnets permitting contacts 'I8 to close establishing a starting circuit through the reset motor RM, whereupon, at the end of the current tabulating operation, the machine proceeds into a resetting and total printing operation. The starting circuit through the reset motor RM extends as follows: Through the reset motor RM, reset clutch magnets |66, contacts 18, wire |61, cam contacts L| now closed, automatic reset switch, stop key contacts |65, cam contacts P3 to the other side of the line. Energization of clutch magnets |66 closes contacts |68 setting up a holding circuit through the reset motor RM, clutch magnets |66, contacts |68, wire |69, cam contacts L2 to the other side of the line. This circuit keeps the reset motor operating until just before ythe end of the reset cycle when contacts LPT, close deenergizing magnets 64 and 65 which drop their armature closing their respective contacts. This sets up a shunt circuit around the reset clutch magnets IE6 through contacts Pl closed shortly after the beginning of the reset cycle, contacts 64a, wire |69, contacts L2 to the other side of the line, deenergizing the reset clutch magnets |66. This opens the contacts |68, the reset motor, however, continues to run until the end of the reset cycle when the cam contacts PI open. If the auto start switch is closed the tabulating motor TM will again be energized when the relay 65 is deenergized closing its contacts 65a, and when the P3 contacts are closed near the end of the reset cycle.

In order to read off the total standing on the totalizer a frame 54 (Fig. 3) secured on a rock shaft receives an invariable excursion first counterclockwise and then clockwise to normal position at each total printing operation. The shaft 55 may receive its oscillatory movement from any suitable source preferably that disclosed in the above mentioned Lake patent.

A number of feeler fingers 56 are loosely mountcd on the shaft 55 and are resiliently urged counterclockwise against the bail |54 of the frame 54 by springs 51 each having one end secured to an angular plate |55 fast on the bail |54 and the other end anchored to a projection (not shown) on the rear end of its corresponding finger 56. At their outer or free ends the fingers 56 carry adjusting screws 58.

Stepped cams 59 mounted on a shaft 60 are adapted to rotate in the planes of the corresponding screws 58 (see Fig. 1). Gears 66 attached to the cams 59 mesh with the gears |1 which in turn mesh with the totalizer gears 15. Thus the gears 66 and the cams 59 are set to positions corresponding to the setting of the totalizer gears.

As the shaft 55 rocks counterclockwise, the fingers 56, due to the springs 51, are carried therewith until the screws 5B come intov contact with and are arrested by the stepped cams 59.

The frame 54 continues its invariable excursion carrying therewith a contact 61 mounted on the rearwardly extending part of said frame. When the movement of the fingers 56 is arrested by contact of its screw 58 with the corresponding cam 59, the contact 61, continuing its counterclockwise movement with the frame 54 about pivot 55, wipes onto the curved end of an arm 68 carried by but insulated from the now arrested finger 56. This, by means of another contact 69, closes a circuit through the printer magnets 49 (Figs. 5 and 7) for that denominational order, and, since the nger frame 54 is rocked in synchronism with the upward movement of the type carrier 23, the movement of said type carrier is arrested as the particular type corresponding to the setting of the totalizer gear arrives at the printing point. The total standing on the totalizer is then printed and the totalizer then reset to zero in the usual well known manner.

Before the printer magnets 49 can be energized on total printing operations it is necessary to close contacts 18 (Figs. 1 and 7), a pair of which contacts is-associated with each counter. The contacts 10 normally are closed manually as a preliminary to operation of the machine when it is desired to automatically initiate a total printing and resetting operation upon the occurrence of a group change. This is accomplished by shifting the knurled collar 1| (Fig. 1) toward the right to couple the reset shaft 12 to the reset gear 13. An annular groove 14 in the coupling 15 embraces one arm of a bell crank 16 rocking said bell crank clockwise. The rounded end of the other arm of the bell crank, upon clockwise movement thereof, closes the contacts 19.

However, if the total printing and resetting are controlled by the manually set knobs 1|, the totals will be printed and the totalizers reset at each card group change. Since it is an object of this invention to suppress total printing and resetting the totalizers until the weight of shipments equals or exceeds 2,000 lbs., other means is provided to operate the reset clutches 15 (Fig. 1) and to prevent nergization of the printer magnets 49 until the card group change succeeding the accumulation of 2,000 or more on the weight totalizer.

This means includes magnets 19 (Figs. 1 and '7). Means is provided under the control of the weight totalizer to energize the magnets 19 thereby to effect automatically the energization of the printer magnets when the registered weight equals or exceeds 2,000 pounds. This means includes a magnet 86 and a magnet 81. These magnets are wired in series and are connected to the line through a normally closed switch 88 and are adapted to be energized through a pair of contacts 89 operated by the weight totalizer. The contacts 89 are closed when the 1000 denominational order totalizer wheel passes from 1 to 2 by mechanism to be described later. These contacts when closed set up a circuit through the switch 88, magnet 86, magnet 81, contacts 89, wires and 92 to the other side of the line. This circuit energizes magnets 86 and 81.

It may be stated here that by opening the switch 88 the machine may be made to function in its normal manner, printing the totals and clearing the totalizers at each card group change.

Energization of the magnet 81 closes contacts 90 setting up a holding circuit through switch 88, magnet 86, magnet 81, contacts 90, cam operated contacts 9| and wire 92 to the other side of the line. This holds the magnet 86 energized which holds its contacts 93 closed to energize the magnets 19 upon closing of their respective contacts LP8, LP9 and LP|0. These contacts close early in a reset operation and remain closed until near the end of the cycle.

It is to be understood that the magnets 86 and 81 Will not be energized, and consequently the contacts 93 will not be closed to energize magnets 19 unless the contacts 89 are closed at some point during the tabulating of a group of cards, and, as

above stated this can only occur when the 1000 denominational order totalizer wheel of the weight totalizer passes from 1 to 2. The mechanism whereby the contacts 89 are closed under the above condition is described as follows:

A rock shaft 94 (Figs. 1 and 3) suitably supported in the machine carries an arm 95 extending horizontally toward the right (Fig. 3), the free end of which arm rests above the insulated upper blade for the contacts 89. Two arms 96 and 91 secured to the shaft 94 between them carry a bail or rod 98 extending across the planes of the stepped cams 59 for the 1000 to 10,000,000 denominational orders, inclusive. Springs 99, only one of which is shown (Fig. 3), urge the arms 96 and 91 and the rod 98 in a counterclockwise direction, which movement is limited by an arm |00 secured on the shaft 94 resting against a stop stud |0|.

Obviously clockwise movement of the bail 98, shaft 94 and arm 95 from the positions in which these parts appear in Figure 3 will close the contacts 89 thus setting up the condition to render the total printing and resetting mechanism effective as set forth above.

The stepped cams 59 are shown in their 0 position in Fig. 3, and when an amount is added thereon, these elements are rotated counterclockwise as viewed in this figure. It will be noted by examination of Figures 2 and 3 that the rod 98 has a notch cut therein opposite the 1000 denominational order cam 59. Also that the bottom of the notch is equi-distance with the next step on the cam 59, which step represents the 8 position with respect to the feeler finger 56, from the center of the shaft 60. Consequently the thousands cam plate 59 may be advanced one step to add one thousand onto the totalizer without disturbing the rod 98. But if the thousands order cam 59 is advanced to the 2 position the rising face |02 between the 8 and 9 position on the cam 59 rocks the rod 98, shaft 94 and arm 95 clockwise to close the contacts 89.

Should the stepped cam 59 for the 1000 orders be advanced from the or l position to the 3 position at one continuous movement the rod 98 and shaft 94 would be rocked clockwise to close the contacts 89, and then immediately counterclockwise to normal again opening the contacts. However, this brief closing of contacts 89 is suicient to energize magnet 81 thus setting up the holding circuit as set forth above.

Another condition may obtain by adding an amount, for instance 10000 on the totalizer without disturbing the setting of the thousands element 59 from its zero position. By reference to Figure 2 it will be noted that the rod 98 has no notches opposite the remaining stepped cams 59 cooperating therewith. If any one of the higher order cams 59 be rotated one step, the rise between the 'l" and 8 positions of said cam will immediately rock the rod 98, shaft 94 and arm 95 clockwise to close the contacts 89 for the above stated purpose.

The contacts 9| (Fig. 7) are normally closed in order that upon closing the contacts 89 by the totalizer the holding circuit may be at once set up, through the magnets 86 and 81. However, it is necessary to break the holding circuit near the end of the reset cycle, hence the contacts 9| whose cam is timed to open said contacts at the proper time. Just before the contacts 9| open, the magnet 6| and a magnet |03 are energized by the closing of contacts LP'I. The magnet |03 when energized closes its contacts |04 which contacts are wired parallel to the contacts 93 thus holding the magnet 19 energized to maintain the clutches or couplings 'l5 (Fig. l) in their adjusted positions until the end of the resetting movement. The magnets 19 are deenergized by their respective cam contacts LP8, LPS and LP|0 (Fig. '7).

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.

In a machine of the class described, the combination of a plurality of totalizers, item entering means, total takingr means for all of said totalizers, automatic means to initiate a total taking operation, ,and means controlled by one of the totalizers to render the total taking means for all of the totalizers ineffective until a predetermined amount has been accumulated on said one totalizer.

13. In a machine of the class described, the combination of a plurality of totalizers for accu.- mulating items, totalizer resetting mechanism operative at the ends of groups of items for simultaneously resetting all of the totalizers, and means operated by one of said totalizers to determine whether or not the totalizers are to be reset at the end of a group of items.

14. In a machine of the class described, the combination of a plurality of totalizers for accumulating items, totalizer resetting mechanism operative at the ends of groups of items for resetting all of the totalizers, and means operated by one of said totalizers when a predetermined amount has been accumulated on said one totalizer to render the resetting mechanism for all of the totalizers effective.

15. In a machine of the class described, the combination of a plurality of totalizers for accumulating groups of items, totalizer resetting mechanism operative at the ends of groups of items, and means operated by one of the totalizers to suppress resetting of all of the totalizers until a predetermined amount has been accumulated on said one totalizer.

16. In a machine of the class described, the combination of a totalizer for accumulating items, total taking control mechanism operative at the end of a group of items, normally inoperative total printing mechanism for printing totals from the totalizer, a bail operable by any one of the totalizer elements above an intermediate order on item entering operations, and contacts closed by said bail to render the total printing means eiective.

17. In a machine of the class described, the combination of a totalizer, item entering means, total taking means, contacts to render the total taking means effective, and a bail actuated by any one of the denominational order totalizer elements above an intermediate order to operate said contacts when a predetermined amount has been accumulated on the totalizer.
