17 Claims.

This invention relates to accounting machines and similar business machines and is directed particularly to the totalizers of such'machines.

The invention is embodied in machines of the general type shown in the following United States Patents Nos. 1,619,796; 1,747,397; 1,749,960; 1,761,542; and 2,262,258, issued March 1, 1927; February 18, 1930; March 11, 1930 June 3, 1930; and November 11, 1941, respectively, to Bernis M. Shipley; No. 2,175,346, issued October 10, 1939, to Maximilian M. Goldberg; No. 2,141,332, issued December 27,, 1938, to Charles H. Arnold; 1,693,279, issued November 27, 1928, to Walter J. Kreider; No. 2,345,839, issued April 4, 1944, to Pascal Spurlino, Mayo A. Goodbar, and Marvin D. Frost; No. 2,351,541, issued June 13, 1944, to Everett H. Placke; No. 2,361,662, issued October 31., 1944, to Pascal Spurlino and Conrad Ranch; and No. 2,373,510, issued April 10, 1945, to Pascal Spurlino, Everett H. Placke, Willis B. Eickman, and Arthur G. Kramer.

More specifically, this invention relates to the control of the transfer or carry mechanism associated with the several denominational orders or units of the totalizers and includes a novel control'of said transfer mechanisms whereby the plurality of totalizers on each of the several lines of totalizers may be split or divided so as to create, from a certain number of totalizers of high capacity on each line, agreater number of totalizers of lower capacity on each of said lines.

For an illustrative example, a machine having a keyboard of fifteen denominational orders or units and three lines of totalizers which have been designated upper, front and back lines, is shown herein. The front and back lines each has nine totalizers thereon, and the upper totalizer line has ten totalizers thereon. Each of the 28 totalizers has a capacity of fifteen denominational units.

With applicants invention each of the nine totalizers on the front and back lines, in one instance, can be separated or split into forty-five totalizers, each having a capacity of three deten of said twenty totalizers each having a capacity of six denominational units and the other ten of said twenty totalizers each having a capacity of nine denominational units; and in still another instance such totalizers on said frontand back lines can be separated or split into twentyseven totalizers, nine of the twenty-seven totalizers each having a capacity of three denominational units, nine more of the twenty-seven totalizers each having a capacity of nine denominational units, and the remaining nine of "said twenty-seven totalizers each having a capa'city'of three denominational units, these la'st'nine totalizers being used to automatically count 1 upon each addin operation of the machine," and said totalizers on the upper line can be separated or split into thirty totalizers, ten of said thirty totalizers each having a capacity of three denominational units, ten more of the thirty totalizers each having a capacity of nine denominational units and the remaining ten of said thirty totalizers each having a capacity of three denominational units, the last ten totalizers being used to automatically count 1 upon each adding operation of the machine; and in still another instance; and by the use of this same invention the nine totalizers on the front line and on the back line can be controlled to function as nine totalizers, each having the full capacity of fifteen denominational units, and the ten totalizers on the upper line at the same time controlled to function as ten totalizers each having the full capacity of fifteen denominational units; I

From the above generaldescription it is clear that by the use of applicants novel variable split control mechanism, a machine having three lines of totalizers with nine totalizers on the front line, nine totalizers on the back line, and ten totalizers on the upper line, can be divided or split, so that the machine has a total capacity of totalizers in one instance, 56 totalizers in another instance, 84 totalizers in another instance, and at the same time and by the use of the same mechanism the totalizers can be all rendered normal sothat the machine has a capacity of 28 totalizers, each having the full denominational capacity of 15 units. By the use of'applicants novel, variable-split control mechanism the machine may be putin:

For example, many public utility ccmgive a five-way split, namely, 3333--3, which divides the machine into 140 totalizers, 139 of which are used to count the various amounts of consumption that are used by the various customers. They divide their consumption figures in those ending in 0, 2, 4, 6 and 8, and each of the three-way splits then is used to represent those digits 0, 2, 4, 6 and 8, and the control keys on the machine in the transaction banks are used to designate the tens and hundreds numbers preceding the units digits and 0, 2, 4, 6 and 8. For example, a customer who has used 247 units of consumption, the operator in making the analysis would press the 1 key in the highest split, and along with it would press the 24 transaction key. This key would select totalizer #24 of this split, and 1 would be added into that totalizer by the depression of the 1 key. Whenever a figure ends in an odd number, they use the next higher even number. Now for all customers who have used 247 units, the operator will press the same keys. The result of this analysis can be printed, which will tell the company how many customers use 248 or 247 units of consumption. Such figures may be obtained from the individual detail strips of the machine of the typ shown in the Spurlino and Ranch Patent No. 2,361,662.

- After the operator has analyzed all of the various consumptions, then .a chart is used from which the operator obtains the charge for the groups of units and writes the amount the charges opposite the various consumption accumulations. The variable split control mechanism may be moved into another position to split the totalizers into groups having six and nine denominational orders and then the amounts from the different types of consumptions may be further analyzed in these two splits in the machine.

Such types of analysis may be used for breakdowns in consumptions in the different types of services, such as industrial services, commercial, domestic, rural, and other miscellaneous types of services which are sold by the various utility companies.

After all of these amounts are accumulated or added into the various totalizers under the different variable split control the totals may be printed from said totalizers by printing mechanism (not shown in this application), but which is substantially identical with that shown in the above mentioned Arnold Patent No. 2,141,332.

Central offices of chain stores may wish to analyz their various types of business from their different stores throughout the country and here again the variable split control mechanisms may be used to divide the various groups of totalizers into larger groups of totalizers of smaller capacities when higher capacity totalizers are not needed for the various analysis breakdowns. Again, in other types of businesses where inventory controls are to be analyzed, this mechanism renders the machine adaptable for uses in that type of work whereby the various items of the inventory may be divided, for example, into 140 different classes when the variable split control mechanism is used to split the totalizers from the normal 28 totalizers into the 140 totalizers, as above stated.

It is, therefore, an object of this invention to provide a novel variable split control mechanism for controlling the transfer or carry mechanism between various denominational orders of the totalizers so as to control the machine to split the totalizers into variable numbers of totalizers of various denominational capacities, dependin upon the positions into which the variable split control mechanism is set prior to the beginning of the first operation or the machine.

Another object of this invention is to provide a novel mechanism to control the transfer mechanisms'between a certain pluralityof denominational elements of the totalizers ofa plurality of lines of totalizers with a single manipulative member to variably control the different types of splits in the totalizers, as desired, depending upon the particular type of work which it is desired to have the machine do.

Another object of this invention is to provide a novel mechanism to control the transfer mechanisms between certain denominational elements of the totalizers to cause a split in the totalizers on all three lines by a common mechanism, and at the same time cause the totalizers split off from the main group of totalizers to automatically count 1 for each operation of the machine into each of the selected totalizers on each of the three different lines. 7

Another object of this invention is to provide a novel form of variable split control mechanism adaptable for use in machines having a plurality of totalizer lines, each line having thereon a plurality of interspersed totalizers.

A still further object of the present invention is to provide novel mechanism for controlling the transfer mechanism intermediate certain of the denominational elements of a plurality of totalizers on a plurality of lines, and in addition to provide a differentially adjustable means to control the effectivity of the means to determine which of the plurality of means that controls the transfer mechanisms shall become effective for any particular operation.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a'preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

GENERAL DESCRIPTION Described in general terms, the machine embodying the present invention is of the same general type as that disclosed in the above men tioned Shipley patents, which disclose a machine having three lines of a plurality of interspersed totalizers. In the present instance the front and back lines are each provided with nine totalizers, and the upper line has ten totalizers. All of these totalizers, as shown by the diagrammatic View of the keyboard, have a capacity of dc nominational units, and there is one set of differential mechanisms, such as that shown in Fig. 2, for each bank of keys shown inFig. 1. These totalizers are operated :by the differential mechanisms under the control of these amount keys while the selection of the totalizers to be operated is accomplished through differential mechanism shown in the Shipley patents under the control of the three banks of keys marked Transaction Rows," shown in Fig. 1.

The above amount differential mechanisms serve to adjust printing mechanisms such as those shown in the above mentioned Arnold Patent 2,141,332, whereby the results obtained in the various totalizers may be printed.

The present invention, however, as above mentioned, concerns particularly novel mechanism for controlling the transfer mechanisms between certain denominational orders of the totalizers, whereby the totalizers may be separated or split into variable numbers of totalizers of lesser denominations than the normal totalizers of 15 denominati'onal units.

DETAILED DESCRIPTION Framework, operating mechanism and releasing mechanism Only so much of the framework of the machine, the machine operating mechanism and the ma chine releasing mechanism, has been shown as is necessary, and for a further description thereof reference may be had to the above mentioned patents. I The mechanism in generalis supported between side irames 2| (Figs. 2 and 6). A main operating shaft 22, used to operate the mechanism of the machine may be driven by hand or by motor as mentioned in. the above mentioned Shipley patents. A release shaft 23 or key lock line, as it is known in this art, is shown in Fig. 3, which shaft is given a clockwise rotation upon depression of the motor bar or any of the keys in the total row, as-shown diagrammatically ii; Fig.1.

Keyboard The keyboard of the machine is diagrammat ically shown in Fig. 1 and consists of a motor bar 24, a row of total keys 25 marked Read and Reset, a row of transaction keys 26 marked 1 to 9; a row of transaction keys 21 marked '10 to 18; a row of transaction keys 28 marked 19 to 27; and fifteen rows of amount keys 30. There is also projecting through a cabinet 3| a lever 32, to be hereinafter described, which lever controls the novel mechanism for controlling the transfer elements intermediate various certain denominational elements or wheels of the sev eral totalizers on each of the three lines.

The machine proper, including all of the printing mechanism thereof, is enclosed in this suitable cabinet 31' (Figs; 2 and 3) having the necessary hinged sections for the operator to gain access to certain parts of the machine whenever necessary. All of the hinged sections, wherever necessary, are provided with suitable locks to prevent unauthorized persons from having acto the inner parts of the machine.

A retaining lever Q3, associated with the lever also projects through an opening in the cabinet 3!. The purpose of this lever'will be hereinafter described.

Amount keys As above mentioned, there are fifteen banks of amount keys (Figs. 1 and 2) which amount banks aresubstantially identical with the amount banks shown 'and'described in the above men-- ti'oned Shipley patents, and therefore, but a brief description thereof will be given herein. The keys 33 are slidably mounted in key frames'35, supported at their upper and lower ends by rods 3% and Si, respectively, carried by the machine side'frames 25. Each of these keys 3B cooperates with a control bar and a locking bar (not shown), and is held in its normal outer position by the usual key restoring spring 38. The keys are released'iiear the end of the operation of the machine in the manner shown and described in the United States Letters Patent to B. M. Shipley No. 1,789,418, dated" January 20, 1931.

Cooperating with" each bank of keys is a zero stop'pawl as, the function of which is to stop the differential mechanism in the zero position when no key in that respective bank is depressed The zero stop pawls'39 and their functions are fully illustrated and described in the above mentioned shi'pley patents, and it is therefore thought unnecessary to go into any further description thereof.

Control keys The three rows of control keys 2G, 21 and 28, are mounted in key frames (not shown) but similar to the frames 35, and are for the purpose of selecting totalizers onthe upper, back and front lines mder the controlof keys 26, 2'! and 28 respectively.- Y.

;.'Ihese keys and their means, which they control for the selection of the totalizers, are substantially the samev as those described in the above mentioned Shipley patents, and therefore no further description thereof is thought neces- The motor bar 24 is used to release the machine for operation in adding operations, after the-depression of, the proper amount keys to record the desired transactions,.and in connection with which ver one ofthe transaction keys 26, v

2? or iicis to be depressed for that transaction. Difi erential mechanism 1 The differential mechanisms of the machine are employed to-differentially operate the different totalizers, and to sele'ct'themfor operation, and also to set type" carriers 'in the' printing mechanism as controlled by the banks of keys in adding' operations and by the totalizers in total and sub total .operations.

Amount difierential mechanism The amount differential mechanism will be briefly described first. There is one complete differential unit for each amount bank, but as they are all identical in construction and operation, only one Will be described.

Each amount differential unit (Fig. 2) is supported by the usual hangers 4|, mounted on rods 42 and guided at their upper ends between the key frames 35.

To drive the differential mechanism of the machine, the drive shaft 22 is provided with a plurality of pairs of cams 43, each pair cooperating with rollers 44 (only one of which is shown) carried by a Y-shaped lever 45, of which there is one for each bank of keys in the machine. This lever 45 is pivoted to the hanger 4|.

Loosely mounted on the studs 46, carried by the hangers 4|, are differentially movable actuators 41 carrying racks 48 and transfer arms 49 for operating totalizer pinions 50. There are three sets of racks 48 and three sets of transfer arms 49 to cooperate, one set each with the totalizer pinions 50 on the upper, front and back totalizer lines. The levers 45 are connected by links to driving segments 62, loose on the studs 46. The driving segments 62 adjacent the banks of amount keys are connected to the differentially movable actuators 41 by latches 63, each supported by an arm 94 and a lever 65 pivoted on the corresponding actuator 41. Springs 66 pull the latches into engagement with shoulders on the driving segments 62.

When the segments 62 are driven by their earns 43, the differentially movable actuators 41 are carried with their latches up to points where the forwardly extending arms of the levers 65 engage the inner ends of th depressed amount keys 30. Such engagement results in the disengagement of the latches from the driving segments 62 and the engagement of the forward ends of the latches with the particular one of a series of notches 61 in a bar 68 supported by the particular hanger 4|, which is opposite the latch when it is disengaged. Upon the return movement of each driving segment 62 to normal position, a pin 69 (Fig. 6) mounted on the associated differentially movable actuator 41 is engaged by the inside of the driving segment 62, and said actuator 41 is returned thereby to its normal position.

If a key is not depressed in the bank, the zero stop pawl 39 therefor operates the latch to arrest the differentially movable actuator 41 in its zero position. However, when a key is depressed the zero stop pawl 39 is moved out of its operative position by means fully described and illustrated in the above mentioned Shipley Patent No. 1,619,796.

Total'izers As has been previously mentioned, there are three lines of totalizers, namely, an upper line, a back line, and a front line. The upper line has ten interspersed totalizers each consisting of |5 totalizer pinions or wheels 50. The front line and the back line each has nine totalizers, each of which consists of 15 denominational pinions or totalizer wheels '50. This type of totalizer is fully illustrated and described in the above mentioned Shipley Patent No. 1,619,796, and the totalizer lines are arranged to be moved into and out of engagement with their respective setsof racks 48, carried by the differential actuators 41. The appropriate totalizer on each of the lines, as above mentioned, is selected for operation under control of the keys 26, 21 and 28, shown diagrammatically in Figure l, and under control of totalizer engaging selecting mechanism as shown in the Shipley Patents Nos. 1,619,796 and 1,749,960.

Transfer mechanism When one of the totalizer wheels 50 passes from 9 to 0," a transfer mechanism is operated for causing l to be added upon the totalizer wheel 59 of next higher order. Pivotally secured to the differentially movable actuators 41 are three transfer arms 49, each having two teeth like the teeth of the racks 48. These arms are in the same plane with said racks 48.

The transfer tripping mechanism associated with the three arms 49 for the three totalizer lines is identically the same. Therefore, the tripping mechanism for one denominational order of a totalizer on the front line only will be described, the same reference numbers being given to the transfer elements for all three lines. Pivoted to the arm 49 (Fig. 2) are levers 16, one on each side of said arm. These levers carry a pin 11 held in contact with a projection 18 integral with the rack 48 by a spring 19 stretched between the lever and the differential actuator 41. This spring, during the clockwise movement of the differential rack 48, holds the arm 49 in such a position that the pin 11 is locked in a recess in the projection 18 so that the rack 48 and arm 49 move as a unit. The lever 16 has secured thereto a square stud 80, which normally abuts an end 8| of a transfer lever 82 mounted on a stud 83 on the hanger 4| when the differential rack 48 arrives at zero position. The differential actuator 41 and the rack 48 are normally given one unit of movement counterclockwise beyond zero to their normal position, and consequently the abutment of the stud 88 with the end 8| causes the transfer arm 49 to be held, whereby the pin 11 becomes disengaged from the notch in the extension 18, as is clearly shown on Figure 2. Consequently the differential actuator 41 and racks 48 normally move one step farther than the transfer arm 49.

Fast on a short shaft 85 supported by the hanger 4| is a transfer trip lever 86 (Figs. 2, 3, 4 and 6) having a projection 81 which lies in the path of a long tooth 88 on the totalizer wheel 50 of next lower denomination. Also fast on the shaft 85 is an arm 89 carrying a flattened pin 90, held by a torsion spring 92, in engagement with a shoulder 9| in an opening in the transfer lever 82, one end of said spring 92 being secured to the hanger 4| and the other end to the transfer trip lever 86.

As a totalizer wheel 50 passes from 9 to 0" the long tooth 88 thereof engages the projection- 81 and rocks the lever 66 counterclockwise (Fig. 2). This movement disengages the pin from the shoulder 9| and a spring 93 rocks the lever 82 clockwise and moves the end 8| away from the square stud 80 and brings a shoulder 94 into the path of movement of the stud 80 to regulate the movement of the transfer arm 49. When this occurs, the arm 49 remains locked to the rack 48 during the extra unit of movement past the zero position, which said transfer arm 49 receives, thereby causing 1 to be added upon the totalizer wheel 50 of next higher denominational order.

All displaced transfer devices are restored-to theirnormal positions at the next operation of the machine by a three-armedlever 95, loose on the stud 46. The lever, 95 carries a pin 95 engaged by an edge 91 of the drive segment I52, in the next lower bank, near the end of the clockwise movement of said segment. When the pin 96 is thus engaged by the segment 62, the threearmed lever 95 strikes edges 98 of the levers -82 and rocks said levers counterclockwise until the pins 90 again engage the shoulders -9I, and the transfer trip levers BS'are restored'to their normal positions by the springs 92.

Totalizing operations Duringv totalizing operations, which consist of either read or reset operations, the machine is under control of the keys 25 (Fig. '1), Under control of these keys a plate IIlli (Figs. 4 and 6) is differentially positioned, depending'upon the key which is depressed. During such total and subtotal operations the main drive shaft is given two complete rotations in aclockwise direction. During the first cycle of movement or first rotation of the shaft 22, all of the previously tripped transfer devices are restored to their normal positions, and the'diiferentials all stop in the zero positions. During the second cycle a shaft IDI (Fig. 2) anda segment I02 thereon, are moved counterclockwise to rock a segmental lever I03 slightly clockwise to straighten out atoggle, consisting of links I04 and -lllii the latter of which is pivoted to a lever I 06 carryinga flattened stud IIl'I adapted to cooperate with teeth I08 in a reset spider H19 having an arm III] 'surounding a stud I I I carried by the latch lever 65. 'When the links I04 and I are straightenedga pawl I I2 is moved into the pathof'the long tooth "8B of the totalizer wheel 50. 7 Therefore, during'the' second cycle of a totaling operation, when thetotaliz er wheel is rotatedcounterclockwise and whenthe long tooth strikes the pawl I I2', it rocks said pawlcounterclockwise (Fig. 2) and throughthe links IM and I05 rocks the lever I06 in-a clockwise direction, whereupon the flattened stud; ID'I engages the tooth .108 opposite it'at that particular time, whereupon the reset spider I09 is shipped, which through its engagement with the stu'd III disengages the latch 63 from the driving segment 62 to set the differential mechanism in a position according to the amount which 'was'taken from the associated totalizer wheel.

This mechanism is fully illustratedand described in the Shipley Patent 1,619,796 above mentioned.

Variable split controlanditcm count.

As has been pointed out earlier in this specification, a novel mechanism-has been provided for s litting the totalizers on the three .totalizer lines, namely, the upper, back and front lines, into a variable number of smaller denominational capacities under the control ofthe manually operable, differentially adjustable or positionable lever 32 (Figs. 1 and 3).

When this lever 32 is set in position 1 or neutral position, all twenty-.eight-of the totalizers, that is nine on each of the front and back linesand ten on the upper line, function in their normal manner with each totalizer having its full capacity of denominational orders.

When the lever 32 is'moved into position 2, it controls mechanism to split the ,totalizers on all three lines into. azgreater number of totalizers, namely, forty-five totalizers on. each of the front and back lines and fifty totalizers on the upper line, each of said total of totalizers having a denominational capacity of three orders or units.

When the lever 32 is moved into position 3, it I operates this same mechanism to split the totalizers on the front-and back lines so that each of said lines will have eighteen totalizers, nine of which have a denominational capacity of 6 units and the other nine totalizers each having a Capacity of 9 denominational units, and the totalizers on the upper line are split so that there will be twenty totalizers on this line, ten of which will havea capacity of 6 denominationalunitsand ten of which will have'a capacity'of 9 denominational units. 1

When the lever 32. is moved into position 4, it controls this same mechanism to split the totalizers on the front and back lines so that there will be twenty-seven totalizers on each of the'two lines, nine of which will have a denominational capacity of 3 units, nine of which will havea capacity of 9 denominational units, and the last nine of which will have a capacity of 3 denominational units. These last nine totalizers will be used for item counting and for this purpose the lever 32 controls, in addition to the same mechanism above mentioned, a special mechanism for causing these nine totalizers to be converted into item counting counters. The lever 32, when moved into position 4, causes the upper line to be split into thirty totalizers, ten of which have a denominational capacity of 3 units, ten of which have a denominational capacity of 9 units, and ten of which are used for item counting and have a capacity of 3 denominational units each.

As pointed out earlier, to cause the totalizers to be split into the variable number of totali'zers above mentioned, the transfer mechanisms between certain denominational orders of the totalizers on all of the lines are controlled to accomplish thisjresult. I

To cause the split to occur in the various places above mentioned, the transfer mechanisms between the denominational elements of the totalizers, at the points indicated by the splits, as shown in Fig. l, are prevented from tripping, and consequently there can be. no carry from, for example, the third denominational unit into the fourth denominational unit, thus making the fourth denominational unit the normal units order of a split-01f totalizer, as indicated by position 2.

As indicated by this position, the splits occur between the third and fourth, the sixth and seventh, the ninth and tenth, and between the twelfth and thirteenth denominational orders of the totalizers, and consequently the transfer mechanisms between these orders are prevented from operating when the lever 32 is moved into position 2.

-When the lever is moved into position 3 the transfer mechanisms between the 6th and 7th denominational orders are prevented from actuating) to accomplish the split as indicated by posi- When this lever is in position 4 the transfer mechanisms between the third and fourth. denominational units are prevented from operating to accomplish the Split at this position. However, the' transfer mechanisms between the 12th and 13th denominational orders in this particular case, in order to create an item-count counter, instead of being prevented from being operated are caused to operate each and every time the machine is operated, so that the l3th'o'rder, as indicated by the diagrammatic keyboard in Fig.

1 1 1, then becomes the units order'of the item count counter, and consequently one will be added into this units denominational order each and every time the machine is operated.

Variable split control The mechanism for controlling the variable splits above mentioned will now be described, with particular reference to Figs. 3 and 6 to 9.

Pivoted to the lever 32 is a-link I2I, which is also pivoted to a gear segment I22 loose on the rear shaft IOI. This gear segment I22 meshes with a pinion I23, secured to a shaft I24 carried by the side frames 2|. Also securedto the shaft I24 are four disks I25, I26, I2! and I28, having four positions indicated thereon, which four positions correspond to the four positions of the lever 32, as indicated in the diagrammatic view (Fig. 1).

Cooperating with each of the cams I25to I28 is a roller I3I, carried by a lever I32, pivoted on the rear shaft IIII. A spring I33 connected to each of the levers I32, holds its respective roller I3I in contact with its associated disk I25 to I28. Each of the springs I33 is connected to a lever I34, pivoted on a stud I35, carried by the hanger 4I associated with that particular denominational order of the totalizer. A stud I36 helps to guide the lever I34 during its movements. Each of the levers I34 has a notch I31 which engages the previously described pin 96 on the transfer restoring lever 95 associated with a particular denominational order of the totalizer. Each lever I34 carries a stud I38 held normally, by the spring I33, in front of the lever I32, below a shoulder I39 thereon.

There is a lever I32 and a lever I34 associated with the transfer restoring lever 95 between the third and fourth denominational elements, between the sixth and seventh denominational elements,between the ninth and tenth denominational elements, and between the twelfth and thirteenth denominational elements of the totalizers.

The disks I25, I26, I21 and I28 are notched in the following manner:

Disk I25 has a notch I 40 in the 2 and 4 positions, disk I 28 has notches I40 in the 2 and 3 positions, disk I21 has a notch I40 in the 2 position, and disk I28:has a notch I40 in the 2 position.

Whenever the lever 32 is moved from the neutral position shown in Fig. 3, into any of its other three positions, the link HI and gear segment I22, through the pinion I23, turn the shaft I24, and consequently the four disks I25, I28, I21 and I28, and set them in positions corresponding to the position in which the lever '32 is set.

As shown in Fig. 3, the lever 32 is in position 1 or the position marked also Neutral, wherein each of the disks I25 to I28 has no notches I40, and consequently the rollers I3I on the levers I32 cooperate with the true peripheries of these disks and hold the levers I 32 in the positions shown when the transfer restoring levers 95 are rocked clockwise in the manner previously described, which clockwise movement of these members rocks the levers I34 counterclockwise against the tension of the springs I33, and raises the studs I38 from the position shown in Fig. 3 to a position above and in front of the shoulders I39 of the levers I32, but since the rollers I3I all cooperate with the true peripheries of the disks I25 to I28, the spring I33 cannot rock any of the levers I32 in a counterclockwise direction, and

therefore, at the end of the operation, the springs I33 restore all four of the transfer .restoring levers 95 to their normal positions, as shown in Fig. 3.

However, assume that the lever 32 is moved into position 2, which rotates the shaft I24 counterclockwise to bring position 2 of all of the disks I25 to I28 opposite the rollers I3I of the levers I32.

With the parts in these positions, when the four transfer restoring levers 95 are rocked clockwise, they rock the four associated levers I34 counterclockwise, whereupon the studs I38 are moved upwardly in front of the notches I39, and due to the fact that each of the disks I25 to I28 inclusive has a notch I40 in its position 2, the springs I33 rock all four of the levers I32 counterclockwise and position the shoulders I39 of said levers beneath the studs I38 of the levers I34, and consequently the transfer restoring levers 95 are locked in their restoring positions which holds the transfer levers 82 in the positions shown in Figs. 3 and 4, so that, even though any of the transfer trip levers 88 are tripped by the long teeth 88 of the denominational elements of next lower order, the transfer levers 82 cannot be rocked in a clockwise direction by their springs 93, due to the fact that they are being held in the positions shown in Figs. 3 and 4 by the transfer restoring levers 95, and consequently the torsion springs 92 will immediately restore the tripped levers 86 and their connected arms 89 to their normal positions, thus preventing any transfers from taking place between the third and fourth denominational orders, between the sixth and seventh denominational orders, between the ninth and tenth denominational orders, and between the twelfth and thirteenth denominational orders of the totalizers. As is clearly shown in Figs. 3 and 4, the opening in each of the levers 82 is large enough to provide for the movement of each pin 90 on its arm 89 when the levers 82 are held in the positions shown in Figs. 3 and 4, by the restoring lever 95.

Therefore, the totalizers on the three totalizer lines are split into a greater number of totalizers of smaller-denominational orders, as has been above pointed out.

When the lever 32 is moved into position 3, the transfer levers 82 between the 6th and Ith denominational orders of the totalizers are held in their untripped positions due to the fact that the disk I28 is the only disk which has a notch I40 in the position 3, and consequently the lever I32 associated with this particular denominational order is the only lever which can lock the lever I34 in its moved position by the shoulder I39. The disks I25, I21 and I28 having no notches I40 in position 3, hold the levers I32 associated with these three disks in their normal positions as shown in Fig. 1, and consequently the split at this time in the totalizer lines will be between the 6th and 7th denominational orders only.

When the lever 32 is moved into position 4 a split will occur between the 3rd and 4th denominational orders because in this position only the disk I25 has a'notch I40 in position 4, and consequently the lever I32 associated with this denominational order is the only one which can be rocked counterclockwise by its spring I33 to lock the lever I 34 and the associated transfer restoring lever in their moved or efiective positions,

During the movement of the lever 32 from one poSltiQll 90 another the disks I25, I26, I21 and I28, as the case may be, rock the levers I32 clockwise by engagement with the rollers I3I thereof when the disks are moved into such positions that'ther'e are no notches I40 opposite the rollers I3I. In other words, when the lever 32 is moved from position 2 to position 3, the disks cam the levers I32 back to the position shown in Fig. 3, except the lever associated with the disk I26, which has a notch I40 in position 3 and consequently this lever-will remain in a position to lock the lever I34 associated with the particular denominational order.

Item count When the lever 32 is moved into position 4, in addition to itscontrolling the totalizers for a split between the third and fourth denominational orders, it also sets up a condition whereby mechanism is controlled to cause the transfer trip levers 66 and their connected arms 89 to be automatically rocked during each operation of the machine. This mechanism shown in Figs. 4, 5 and 6 will now be described.

The transfer trip lever 86 intermediate the 12th and 13th denominational orders for the back totalizer line has a finger I4I engaging a stud I42 carried by an arm I43 pivoted on the rear shaft II. This stud I42 projects through a lever I44, which is pivoted on the rear shaft IllI and carries a roller I45 cooperating with the periphery of a disk I46 secured to the shaft I24, which it will be remembered is moved differentially by the lever 32. This disk I46 has a notch I53 in position 4 corresponding to position 4 of the lever 32 and corresponding to positions 4 on the other disks I25 to I28 inclusive.

When the lever 32 is moved into position 4 it rocks the shaft I24 counterclockwise and positions the disk I46 to bring the notch I53 beneath the roller I45. When this occurs a spring I41 (Fig. 4) rocks an arm I43 clockwise. This arm I48 is pivoted on the shaft I24 and is connected by a bail I49 to an arm I58, which in turn is connected by a link I5! to the lever I44, and, therefore, the rocking of the arm I48 by the spring I41, when the notch I53 of the disk I46 is positioned beneath the roller I45, rocks the lever I44 clockwise, whereupon the stud I42 by its contact with the finger I4I rocks the transfer trip lever 86 counterclockwise, which rocks the trip arm 88 counterclockwise and disengages the stud 68 from the shoulder 9| in the transfer lver 82, thus permitting the spring 53 to rock the transfer lever 82 clockwise to. position the shoulder t4 opposite the square stud 88 in the transfer arm 48, so that when the differential is restored to its normal position as previously described, 1 will be added into the item count counter, which consists of the three highest denominational totalizer wheels 50 on the back line.

As long as the lever 32 is in the position the notch I53 of the disk I46 will remain below the roller I45, because the transfer trip lever 86 and its trip arm 89 will be held in tripped position, and consequently the transfer lever 82 will be held in its clockwise position with the shoulder 94 remaining opposite the square stud 86, so that 1 will be automatically added into this denominational order each and ever operation. of the machine.

When the lever 32 is in position 1, 2 or 3, the roller I45 is held against the true periphery of the disk I46 and consequently the spring I41 cannot function, and, therefore, the transfer trip 14 lever 86 and its trip arm as will'not be operated by the lever I44.

In order that the item count counters on the upper and front lines may be operated simultaneously with the item count counters on the back line, there is provided a three-armed lever I56, which is supported by the differential tie rod. Each arm of this three-armed lever I56 has a stud I51 engaged by a forked arm I58. The arm I58 associated with the back totalizer line is connected by a bail I59 to the previously described arm I43, which carries the stud I42 to operate the transfer trip lever 86 for the back line. The arms I58 associated with the front and upper lines are each connected by a bail I60 to an arm I6I, which are pivoted on the upper and front shafts IIII associated with the upper and front totalizer lines. Each arm I6I carries a stud I62, which cooperates with a finger I63 on the transfer trip levers 86 associated with the front and upper totalizer lines.

Therefore, it can be seen that, whenever the transfer trip lever 86, associated with the rear totalizer line is tripped by thestud I42, through the lever I56 and the mechanism just described,

the studs I62 will trip the transfer levers 86 as sociated with the upper andfront totalizer lines. Consequently I will be added into the item counters on the upper and front totalizer lines whenever the item count totalizer 011 the back line is operated to count 13 Disablin of item count Whenever totals or sub-totals are to be taken from the totalizers, it is desirable that the item count mechanism should not function. Therefore, mechanism is provided to prevent the operation of the item count mechanism under such conditions.

This mechanism includes a lever I65 (Figs. 4 and 6) pivoted on the rear shaft IIJI associated with the back totalizer line, which lever'carries a pin I66 projecting into a slot in the previously described arm I48. This lever I65 also carries a roller I61, which cooperates with the total control plate I00. This total control plate I08 is moved clockwise during machine operations whenever any of the total control keys 25 for either a re-add or reset operation is operated, and consequently a surface I68 of this plate I00 is moved opposite the roller I61 of the lever I65, with the result that this lever I65 cannot be rocked in a counterclockwise direction by the spring I41 and therefore, since this lever I 65 cannot be rocked, the arm I48 cannot be rocked, and consequently the pin I42 will not be moved upward, and therefore, no item count can take place during any total or sub-total operation.

When the total plate I88 is in the add position, a low portion I69 of the plate is opposite the roller I61, and consequently the lever I65 can he rocked counterclockwise at that time by the spring I41 and arm I48 when an item count is to be effected with the lever 32 in position 4.

Interlock between machine release means and, control lever 32 As earlier pointed out in this specification. the machine release shaft 23 or key lock line is rocked in a clockwise direction upon the release of the machine in a manner previously described in the above mentioned Shipley Patent No. 1,619,796. This shaft 23 has secured thereto an arm I". Pivoted on the upper shaft IIJI associated with the upper totalizer line is the previously mentioned lever 33, which has a finger I72 and a roller H3, which roller'cooperates with four notches I14 in the lever 32, and is held in engagement with one of the notches I14 by a spring H5, stretched between a stud v on the lever 33 and a stud on the lever 32.

To prevent the machine from being released while the lever 32 is being moved from one position to another, the lever 33 is manually rocked in a clockwise direction, which moves the finger I12 above the arm I! l, and at the same time disengages the roller I13 from one of the notches I14, depending upon the position in which the lever 32 was standing. Now, with this disengagement of the roller I13, the lever 32 may be moved into any one of its positions, 1, 2, 3 or 4, without any danger of the machine being released because the release shaft 23 is positively prevented from any clockwise movement by the finger I12 of the lever 33. After the lever 32 has been set in the desired position the operator releases the lever 33 and the spring I15 rocks said lever 33 counterclockwise and engages the roller I13 withthe appropriate One of the notches I74, depending upon the position into which the lever 32 has been moved.

Since the operations of all the parts have been clearly described, it is not thought necessary to give any further description of the operation of the mechanism.
