This invention relates to cash registers and calculating machines having totalizers in which items may be entered and the totals may be taken therefrom. As is well known in the art, the operation of certain mechanisms of the machine must be different for adding items, than for taking a total. In machines of the class to which the present invention is shown attached, the control of these mechanisms is accomplished by the adjustment of a total lever.

In order to take as much load as possible off of the total lever, the present invention provides a novel means for controlling said mechanisms by the depression of an amount key; that is to say, the operation of. the total lever does not affect the control of these mechanisms, said control being dependent upon the depression, or non-depression, of an amount key.

The present invention is applied to a machine adapted to record single item transactions; multiple item transactions, including the entry of a plurality of items and printing a total thereof.

Certain mechanisms, including the operation of customer counters, the indicator flash plate, and the opening of the cash drawer, are set in operation when entering a single item transaction; or when printing multiple item totals, but not when entering an item of a multiple item transaction. To prevent the operation of these parts when an amount key is depressed for entering an item of a multiple transaction, a special key Sa is provided, which, when depressed, uncouples the mechanism coupled by the depression of an amount key.

The distinction between the registration of an independent single item and a multiple item total during the course of the business day is best illustrated by comparing two kinds of customers. One type of customer comes into the establishment needing only a single item. The payment for this single item is registered upon the machine, at which time several associated mechanisms in the machine are actuated. Thus the money drawer must be released to deposit the payment and make the necessary change; the flash plate of the indicating mechanism is operated for the benefit of the customer, and one of several item counters is advanced one unit to obtain a count, for instance, of the number of people served. The other type of customer comes into the establishment needing several items; for instance, five. Rather than actuate each one of the above mechanisms at the registration of each one of the items, which serves no useful purpose and which imposes a great deal of unnecessary wear upon the machine parts, the machine operates in such a manner that the several items are entered, as on an adding machine, and not until the total is obtained are the several associated mechanisms actuated to allow the termination of the transaction with that particular customer in the same manner as in dealing with a customer who made the purchase of only a single item.

In order that my invention can be more readily understood, an embodiment of the same is illustrated by way of example in the accompanying drawings in which Figure 1 is a lateral view of the various members belonging to one order of the machine, with the key board, differential mechanism, total taking mechanism, and totalizer,

Figure 2 is a lateral view of the controlling mechanism for the total taking mechanism in position of rest,

Figure 3 is a detail thereof with the parts con- 20 cerned in operative position,

Figure 4 is a lateral view of the controlling mechanism that causes formation of totals from several items or multiple-item totals,

Figure 7 is a lateral view of the money drawer controlling mechanism,

Figure 8 is a diagrammatic top view of the setting means of the machine, and

Figure 9 is a lateral view of the differential mechanism adjacent the bank of sellers keys.

The setting mechanism of the cash register illustrated in these drawings comprises five rows of amount keys I I, Figure 8, a total lever 12 which can be set to three positions, viz: Ad (addition), ES (grand total), and ZS (sub-total), and two rows of special keys I3, l4. Row [3 comprises six motor keys I to 6 designed as sellers keys, and a motor key Sr to be depressed to take the multiple item totals of several items. The row I4 comprises a motor key 14a serving to take a total from the main totalizer, an accumulating key Mb (Sa) for the selection of a totalizer for the multiple item transactions, that means causing entrainment during introduction 0 of the amount, of a special totalizer (multipleitem totalizer), and a key I40 denoted clear. causing an idle or money changing operation. The clear key can be depressed only in connection with one of the six sellers keys. 55

It is to be seen from the foregoing that three kinds of totalizers are present in the machine, viz: a main totalizer, sellers totalizers and the multiple-item totalizer mentioned. These totalizers are mounted on the shafts i5, iii, if, Figure 1. Shaft i5 carries the main totalizer which is engaged upon entry of all items and therefore, on termination of the business hours, indicates the running total from all items entered, shaft 16 carries six sellers totalizers in which the items are entered additively and subdivided according to six sellers, while shaft i i carries the multipleitem totalizer which, as mentioned, serves for the formation of totals of several items by being engaged by depression of accumulating key Sa, Figure 8, upon a certain number of items being entered subsequently. The individual totalizers are selected and engaged for operation in a manner known in the prior art by shifting the shafts i5, iii, if through the intermediary of riders I8 and of internal teeth iii of the counting wheels 24. The mechanism for selecting one of the totalizer lines i5, it, or if, and the selection of a totalizer on a line, are not shown herein, but these are shown and described in the French Patent No. 665,190 and in a corresponding United States application Serial No. 296,445. In the present machine, depression of a sellers key selects a sellers totalizer on line i 6 for engagement during an adding operation of the machine. Depression of the So. key selects the multiple item totalizer on shaft if for engagement during an adding operation of the machine. The main totalizer is selected during all adding operations.

During total taking operations, the engagement of the multiple item totalizer on shaft if is determined by the depressed key Sa, which remains depressed at the end of the item entry operation, together with the depression of the S50 key. The non-depression of an amount key, when the Sa and Sac keys are depressed, causes the machine to go through a total taking operation. Therefore, when taking a total from the multiple item totalizer, both keys Sc and Sr must be in depressed position. This prevents the totalizers on lines 86 and if from being engaged. When it is desired to take a total from the main totalizer on shaft 55, only the key is depressed, and when a total is taken from a sellers totalizer, only a sellers key it is depressed. The riders l8 are in permanent connection (not shown in de tail) with differential wheels 22 which'through intermediate wheels 23, 24 are in mesh with teeth 25 of main differential actuators 27 mounted on fixed journals 26. The main differential actuators 2?, by means of a stop 28, co-operate with the foot of the depressed amount key I! and are rocked up to the latter with a scissors movement by means of a differential gear. This gear comprises a transverse lever 29 which through a link 3i pivoted thereon by a pin 36 is hinged to a le ver 32 fixed to a driving shaft 33, Figure 1. Pin 39 is carried by the free end of a lever 50 adapted to swing on a fixed journal 49. The transverse lever 29 further permanently engages the main diiferential actuator 27 by means of a block 34 and by means of another block 35 on auxiliary differential actuator 35. The latter possesses a stop 37: which co-operates with the foot of the depressed key. As soon as, after depression of a key N, shaft 33 has been turned to such an extent that pin 30 is in coaxial alinement with pin 26, then the two stops 28 and 3? have been moved from both sides up to the foot of the depressed key, the main differential actuator 21 having executed a motion of an amplitude corresponding to the key depressed. This motion is transmitted to the engaged totalizers by means of the intermediate wheels 24, 23, 22. A differential setting member 25! is furthermore mounted upon shaft 26, the pin 269 of which is embraced by differential members 21, 36 and in addition operations is set in accordance with the amount key which is depressed and in total-taking operations, in accordance with the amount contained in the adding wheels. The differential member 20E has a toothed portion 202 which meshes with gear wheel 2m to set the appurtenant type wheel, and with gear wheel 2| I, loosely mounted on shaft 266, to set the appurtenant indicating mechanism through gear wheel H2.

The described differential actuating mechanism is used for taking totals in the following manner.

On the auxiliary differential actuator 36 is provided a locking surface 38 in the path of which, previous to the commencement of a total taking operation, is placed a roller 39 mounted on a two- armed lever 42, 43 fixedly mounted upon a hollow shaft 4!, which in turn is rotatably mounted upon shaft 286. During normal registering operations, roller 39 is not in the path of surface 38. A mode-of-operation lever l2 (Fig. 8) controls the position of roller 39 by a suitable transmitting mechanism such as that disclosed in Patent No. 1,899,455. Arm 43 has a noseshaped end and co-operates with a series of locking teeth 44 riveted to the main differential actuator 271. Now, when in the position of the parts illustrated in Figure l, the transverse lever 29 has imparted to it the normal driving motion by shaft 33, this motion is transmitted to the main differential actuator 27 only, since the auxiliary actuator 35 first remains at rest due to its being locked by roller 39 that engages face 38. This motion of the main differential actuator 21 causes a backward rotation, or in the direction shown by the arrow in Fig. 3, of the counting wheel 2| coupled therewith. This is occasioned by the fact that during adding operations the movement of the main differential member 21 is transmitted to the counting wheel 2| during the return movement of the former from its adjusted position adjacent the depressed key. Thus member 21 would move in a counter-clockwise direction in the course of entering amounts into the totalizers. On the other hand, in the course of taking totals in a machine of this type, as disclosed in detail in Patent No. 1,896,936, the counting wheels are in engagement with the differential mechanism during the forward movement of the latter. Thus, the clockwise motion of member 27 would cause a reverse motion of counting wheel 2!, in a counter-clockwise direction as shown in Fig. 2. As the counting wheel 2! passes from position 1 to position 0, Figure 3, then its totalizing tens transfer tooth 45 formed by a prolonged normal tooth strikes and wipes underneath and rocks in a clockwise direction a companion tooth 46 and thereby causes double lever 42, 43, Figure 1, to rock so that roller 39 releases face 38 and the auxiliary differential actuator 36 becomes free, while arm 43 falls into the gap just opposite to its end, of the locking teeth 44 and holds the main differential actuator 2! in the position reached that corresponds to the position 0 of the counting wheel 2| coupled therewith. The execution of the rocking movement of lever 42, 43 is explained hereinafter.

The companion teeth 46, Figure 2, are allowed to be in the path of the totalizing teeth 45 only with total taking operations of the machine, Figure 3. To this end the teeth 46 are swingingly mounted by means of pins 41, Figures 2 and 3, on carriers 48 rigid to journals 49. Each of these journals 49 has fixed on it an arm 5| which by a link 52 is in hinged connection with a plate 53 pivoted on a pin 26. A rod 54 is connected at one end to plate 53, and has an open slot 55 in its other end engaged by a pin 56 of a double lever 51. The latter in turn engages a cam groove disk 59, mounted on a gear shaft 58, Figure 2. On every operation of the machine one full clockwise revolution is imparted to shaft 58 in the course of which revolution the pin 56 is rocked first upward and then downward back to initial position. If the rod 54 assumes the position illustrated in Figure 2, it takes part in the motion of pin 56 so that all of the companion totalizing teeth 46, which in the position of rest of the machine are out of the path of the totalizer teeth 45, are rocked into the path of the latter at the beginning of the machine operation and again rocked out thereof in the course of the operation. Now when in the counterclockwise totalizing rotation of a counting wheel 2| the tooth 46 is urged outward the instant the wheel 2| passes from 1 to 0, this rocking motion of tooth 46 on pin 41 is transmitted by means of a link 6| to a lever 62 the free end 63 of which so acts upon a roller 64 mounted on a plate 65 pivoted on the journal 26 of the order concerned, that this plate by an inclined face 66 thereon acting on a roller 39' of a lever 42' causes the described rocking motion of the two- armed lever 42, 43, Figure 1, and thus release of the auxiliary differential actuator 36 and locking of the main differential actuator 21.

In order to cause engagement and disengagement of the companion totalizer tooth 46, Figure 2, only with total taking operations, the provision is made that these motions do not take place if an amount key is depressed. To this end the rod 54 is hingedly connected by a link 61 with an arm 68 rigid to a shaft 69, Figure 1. This shaft has further rigid to it below each row of amount keys I an arm II which by means of a pin I2 engages the bifurcated end of a rod I3 hinged to a slide I4 allotted to the row of amount keys concerned. Slide I4 by inclined slots 15 co-operates with lateral pins I6 of the amount keys and is shifted downward by depression of one of them, the rod I3 then imparting to arm II and shaft 69 a counterclockwise partial rotation. This causes a rocking motion of rod 54, Figure 2, so that it disengages pin 56 and by a bifurcated lug 11 engages a stationary pin I8. Upon an amount key N being depressed, rod 54 and therewith the totalizing companion teeth 46 are held in position of rest and cannot partake of the motion of lever 51.

As above mentioned, means is provided for controlling certain mechanisms to perform their functions only when taking a multiple item total, or when entering single item transactions. These mechanisms are under the control of the amount keys and the Sc key. Thus the depression of an amount key without depressing the Sa key, as when entering single item transactions, causes these. mechanisms to operate; also the depression of the So key without the depression of an amount key causes them to operate. But the depression of both an amount key and the Sa key prevents their operation. The latter operation is for entering items of a multiple item transaction. Thus it is seen that the key Se, in addition to selecting the multiple item totalizer, also causes other mechanism to operate to obtain the proper results. This other mechanism is illustrated in Figure 4. In a manner resembling that illustrated in Figure 2, the shaft 69 which is rocked upon depression of an amount key N, is connected by an arm I9 rigid thereto and a link 8| with a thrust rod 83 carried by a loose rocking arm 82. Rod 83 by its lower slotted end 84 engages a pin 85 of a three- armed'lever 86, 81, 88 which by a roller 89 engages the curved groove of a disk 9| rigid to the gear shaft 58 and receives an oscillatory motion in each operation of the machine. The threearmed lever 86-88 is loose on a shaft 92 from which the drive of the mechanisms concerned is derived. An arm 93 is further rigidly connected to shaft 92 which arm by links 94, is in hinged connection with the one arm, 96, of a two-armed lever 96, 98 loose on a fixed pin 91. Arm 98 has attached to it a thrust rod 99 connected by its other end to a slide I 8| which by means of an inclined slot I82 cooperates with a pin I83 provided on the stem of the key Sa. Upon this key being depressed, which couples the totalizer on shaft IT for operation, a clockwise swing motion is imparted to the two-armed lever 96, 98 so that link 95 is displaced to the left. Upon however an amount key being depressed, the rod 83 is swung to the right. Now rod 83 carries a lug I84 which co-operates with a lug I85 of link 95. In the position of the parts illustrated in Figure 4 in which neither an amount key II nor key Sa is down, the up and down motion of rod 83 caused by disk 9| does not exert any influence upon shaft 92, since lug I94 freely passes past lug I85. The machine operates from this setting of the parts upon the zeroizlng of the sellers totalizers mounted on shaft I6, corresponding to the sellers keys I3, or of the main totalizer on shaft I5, corresponding to the key I4a. When rod 83 had been swung however to the right by depression of an amount key, the lug I84 thereon is moved into alinement with the lug I85, and upon subsequent downward movement of the rod 83, the lug I84 strikes lug I85 to rock link 95 about the pivot on the arm 96, to lower link 94 and to rock arm 93 and shaft 92 in a clockwise direction (Fig. 4). Therefore, when entering single item transactions; that is, an operation wherein an amount key II is depressed but the Sa key is not depressed, the shaft 92 will be rocked clockwise.

When taking a total of a multiple item transaction the So key is depressed, but no amount key II is depressed. Depression of the Sa key, through slide I8I, link 99, and two armed bar 9698, shifts the link 95 to the left (Fig. 4) to position the lug I85 beneath lug I84. Subsequent operation of the machine rocks the shaft 92, through cam 9|, bar 86, stud 85, rod 83, lug I84, links 95 and 94, and arm 93.

When entering the items of a multiple item transaction, the shaft 92 is not rocked. As before mentioned, when entering an item of a multiple item transaction, an amount key N and the Set key are depressed. Depression of an amount key II moves the lug I84 into alinement with lug I85, and the subsequent depression of the So key shifts the lug I85 to the left out of alinement with the lug I84. Therefore, upon operation of the machine with an amount key M and the So key depressed, the lug I64 misses the lug I85 and the shaft 92 is not rocked.

Thus it is clear that the shaft 92 is rocked only when single item transactions are entered, or when the total of a. multiple item transaction is taken. In all other operations the shaft 92 remains at rest.

The Sa key is held depressed during a series of multiple item entries, and this key stays down until the total of the multiple item transaction is taken. For this reason a motor key S33 is provided to release the machine for the taking of the total of the multiple item transaction.

The Sa key is held depressed during the series of item entries by a hook I91 of a detent I06, connected to the arm 93 by a pin and slot connection I09III on a link I69, the upper end of which link is connected to the detent I96.

Rocking of the shaft 92 during the multiple item total taking operation serves to release the 811 key. Clockwise rocking (Fig. 4) of shaft 92, through arm 93 and link I68, lowers detent I96 to withdraw the hook I9? from the stud I93, to release the Sa key to its home or normal position.

Out of other mechanisms that can be actuated by shaft 92, first of all the item counters enter into consideration, because these counters are advanced preferably only when independent single items are entered or intermediate totals taken of several items. The individual item counters II2, Figure 5, are advanced by oscillating pawl carriers II3 actuated by toothed segments II5 oscillating on fixed journals I54. The segments I I5 in their turn are actuated by an arcuate swing member II'I mounted on links II 6 and having a rack I I8. The latter is in mesh with a pinion I2I carried by a differential actuator I I9 and is capable of being selectively brought to mesh with each of the segments I I5. The setting of the differential actuator H9 is performed by the following arrangement. A differential mechanism is arranged in the sellers key bank (Fig. 9) which resembles the differential mechanisms in the amount key banks with the exception that the parts 38 to 44 for causing an alternate locking .of the differential members 21 and 36 are eliminated. By means of the differential mechanism shown in Fig. 9 the differential member 29! with its pin 299 is set by means of the differential members 22?! and 236 corresponding to the foot of one of the depressed keys I3. The setting member 29I is provided with a gear tooth portion 292 in mesh with a wheel 293 which serves to set the type wheels, and with another wheel 294 which is in further engagement with the wheel 295 to set the indicating members. The gear wheel 204 is fixed upon a shaft 206 which carries another gear wheel 29? (Fig. 5), meshing with the toothed portion 298 of the differential actuator H9 which selectively engages the item counters. By the above system of connections, the diiferential actuator I I9 is always adjusted corresponding to the depressed keys I3, and thereby the desired item counter appurtenant the proper sellers key is selected. When a downward motion is im parted to swing member I II, this motion is transmitted by pinion I2I to the segment I I5 just engaged and therewith to the respective pawl carrier H3, so that the appurtenant item counter is advanced one unit. Now the motion of swing member II I is caused by means of shaft 92. To this end the lower link II6 is connected by a rod I22 with an arm I25 rigid to shaft 92.

In a similar manner the exhibiting and obturating motion of the flash-plate of the displaying mechanism is controlled by shaft 92. The flash plate I29, Figure 6, is loosely mounted on the shaft I 21 that carries the indicating rollers I28 and through rods I29, I3! and a two-armed lever I32 is hingedly connected to an arm I33. Under the action of a spring I34 the flash plate tends to assume the exhibiting position shown in Figure 6. Arm I33 which is pivoted on a fixed pin I35, by a roller I36 cooperates with a cam disk I 31 rigid to gear shaft 58 in such a manner as to have imparted to it a downward motion at the beginning of an operation of the machine, from the position illustrated in Figure 6. In this lower position of arm I33 a recess I38 of a locking member I39 loose on shaft 58 engages the front end of arm I33 so that it is locked in lower position and the flash plate I26 thus in obturating position. Hence, if the flash plate be not in obturating position already from the preceding machine operation, it is moved thereto at the beginning of each machine operation. Generally no record can therefore be read off on the display rollers. Upon entering single items, however, or taking an intermediate total of several items, a partial rotation is imparted to shaft 92 as described. Shaft 92 has rigid to it an arm I4I which so co-operates with an arm I42 integral with looking lever I39 that upon shaft 92 rocking, lever I39 is swung to the left, arm I33 is released and flash plate I26 can rise to exhibiting position under the action of spring I34. It results from the foregoing that the indicating rollers are not exhibited in taking grand totals from the main totalizer, in idle operations and in entering single items belonging to an intermediate total of several items.

The money drawer is to be released upon entry of independent individual items in the machine or when an intermediate total of several items is taken. The release is not desirable when the individual items making up such an intermediate total are entered. Therefore, it is quite possible to derive the impulse for the release of the drawer from shaft 92. Furthermore, since the drawer is to be opened also with idle operations for the purpose of changing money, it is necessary that the drawer mechanism be not only controlled by the amount keys and key Sa, but that the clear key may also release the mechanism. To this end shaft 92, Figure 7, has fixed to it an arm I43 that co-operates with a lateral lug I44 of a twoarmed lever I45 rigidly connected to shaft 92. The lower arm of lever I45 carries a pin I46 normally embraced by an open slot I41 of a thrust rod I48. The latter is hinged to an angle lever I49 fulcrumed on a fixed shaft. The end of the upper arm of angle lever I49 engages an annular recess I5I of a rotatable and shiftable drawer releasing bar I52. This bar is selectively adjusted (in a manner not shown) to the different sellers drawers, while the drawer just selected is released by an upward motion of rod I52. It is evident that as long as the thrust rod I48 is engaging pin I46, the drawer is released upon introduction of single items and upon taking intermediate totals of several items.

In order to have released the drawer also with idle operations, the thrust rod I48 by a rod I53 is connected to a slide I54 which by means of an inclined slot I55 co-operates with a pin I56 of the clear key in such a manner that upon depression of the latter the front end of rod I48 is lifted. When this takes place, the open slot I41 releases pin I46. However another open slot I51 provided on an extension I58 riveted to rod I48, now engages from below another pin I59, Figures 4 and '7, which is coaxial with pin I46 but lies in another vertical plane and is carried by the three- armed lever 86, 81, 88. As described above, lever 8688 engages by a roller 89 the grooved disk 9| of shaft 58, and, as an oscil- H with a shoulder to support a stud 304 on the error key 300. Depression of the error key lowers the detent 302 to release the depressed amount key.

Operation A brief description of the operation of the machine will be given, referring more particularly to Fig. 8.

When entering amounts into the machine, the lever l2 must be in the upper or add position as shown in Fig. 12. Depression of one or more amount keys controls the differential actuators to add the amounts into the selected totalizers.

The totalizers are selected by special keys l3, Ma, and Nb. When a single item transaction is to be entered, the sellers key I3 is depressed, which, in addition to releasing the machine for operation by the motor, also selects the sellers totalizer on line l6, and the main totalizer on line l5. Therefore, when entering single item transactions, the amount thereof is added into two totalizers, one on line l5 and one on line 16.

When entering items of a multiple item transaction, the amounts are set on keys II, and then key Sa is depressed and finally the machine is released by depressing a sellers key. At the end of the operation of any multiple item entry operation, the Sa key is held depressed. All the items are entered into the multiple item totalizer, line. 11, into the selected sellers totalizer, line I6 and into the main totalizer, line l5.

When taking totals only one totalizer can be engaged at a time. When taking totals, the main totalizer on line I5 is selected by the key the sellers totalizers are selected by keys [3; and the multiple item totalizer is selected by the 311 key. The key and sellers key l3, are motor keys, so that, when taking totals from either the main totalizer or the sellers totalizers, only one key need be depressed.

When taking totals of multiple item transactions, it is necessary to depress two keys, i. e., keys Sa and Sr. Sa selects the proper totalizer and Sa: acts to release the machine.
