3 Claims.

My invention relates to calculating mechanism andl more particularly to improvements in totalizer, or crossfooter registers, so called, of the type adapted for operation by a toothed actuator or master wheel having uniform increments or steps of rotary movement and laterally movable for denominational selection of number wheels, as exemplified in my patent, Number 1,576,961, dated March 16, 1926.

'I'he principal object of my invention is to provide a register of the above designated type operative for either addition or. direct subtraction, in accordance with the English currency system, and equipped with aligned value indicating wheels of like diameter, and with number wheels arranged for successive operation by the toothed actuator or master wheel.

To the accomplishment of the above, and also subordinate objects as will presentlyappear, a preferred embodiment of my invention has been illustrated in the accompanying drawings which will be set Aforth in detail in the following description and defined in the claims appended thereto.

In the drawings:

Figure 1 is a view in front elevation of a portion ofthe register constructed 'in accordance with my invention;

.Fig 2 is a view in Vertical section taken on the line 2--2 of' Fig. 1;

Fig. 3 is a similar, fragmentary view, taken Aon the line 3-3 of Fig. l;

Fig. 4 is a. View in top.plan.

Fig. 5 .is a horizontal section taken on the line 5--5 of Fig. 2;

' Fig. 6 lis a fragmentary View in vertical transverse section taken on the line 6 6 of Fig. 2;

Figure 7 is a detail side elevation illustrating in full and dotted lines, the relative positions of number wheels of lower and higher orders, respectively, of the register, and

Fig. 8 is a diagrammatic view illustrating the arrangement of value indicating digits onthe value indicating wheels of the register.

Referring to the drawings, I designates a portion of the crossfooter register, including side frame platesI 2 held in spaced relation on the rods 3 by spacing sleeves 4. Mounted, preferably, between the upper front corners of the frame plates 2 is a series of aligned denominational value indicating wheels 5, 6, 1, 8 and 9 freely rotatable upon a horizontal shaft I suitably secured at its ends in the frame plates 2.

As previously stated, in substance, the value indicating wheels are designed to register amounts expressed in the terms of the English currency (Cl. 23S-59) system, hence, they may be termed farthings, pence, shillings and pounds wheels, respectively. 'I'he extreme right hand wheel 5, that of lowest denominational order is the farthings wheel, that of next higher denomination, 6, the pence wheel, the nexttwo wheels 'I and 8 are the units and tens of shillings wheels, respectively, and the succeedingwheels 9 arethe pounds wheels of successively higher denominational order.

The value indicating wheels 5, 6, 1, 8 and 9 arel of like diameter and provided on their peripheries with equi-.distantly spaced digits, as follows: The farthings wheel is provided with three series of digits, each series including 1, 2, and 3 followed by 0. 'The pence wheel, 6, which is of double width, is provided with the digits l to 11 followed by 00, The units of shillings wheel 'l bears the digits l to 9 followed by` 0, and the tens of shillings wheel, 8, bears five series of digits each comprising Il and 0. The .pounds wheels 9 are each provided with the digits, 1" to 9 followed by (l. comparatively wide space is left between the pence wheel and the units of shillings wheel and also between the tens of shillings wheel and the pounds wheels to facilitate reading'the register.

It will be seen that the farthings and pence Wheels and 6 are designed to have twelve uniform increments or steps of' rotary movement during a single rotation thereof, and the shillings and pounds wheels ten such increments or steps. In other words, the instant register is provided with aligned value indicating wheels of like diameter, some of which are designed to be rotated through ten and others through twelve step cycles of movement.

As before intimated, said wheels are designed for operation by an actuator shiftable laterally thereof and rotatable in uniform step by step degree. It has not been considered necessary in the present instance to illustrate and describe the mechanism for rotating the actuator or mov- 'ing the same laterally. Suice it to say that in the particular type of register with which my invention is concerned, the actuator shown at a (Fig. 2) is moved with a typewriter carriage and rotated by the number keys thereof in either direction a number of increments, or steps, corresponding to the value of the key depressed, as disclosed for instance in my patent aforesaid.

In order that the proper degrees of rotary movement may be imparted to said indicating wheels under operation of the actuator |08, a' series of toothed denominational number wheels Il, I2, I3, I4 and l5, (Fig. 3-6) individual to the value indicating wheels 5, 5, l, 8 and 9, and hence, corresponding iii-denominational order thereto, are mounted, preferably, in the. rear of said value wheels 5, in peripherally spaced relation with respect to the latter. The tens of shillings number wheel (Fig. 4) I4 is wider than the others because of the wide spacing between the tens of shillings wheel 8 and the adjacent pounds wheel 9. As clearly indicated in Figs. 2and 3, the actuator II)ai is located above said number wheels for movement thereover.

The farthings and pence number wheels II and I2 are each provided with twelve peripheral teeth equi-distantly spaced in correspondence with the increments or steps of movement of said farthings and pence wheels. The shillings and pounds number wheels I3, .I4 and I5 have ten teeth, respectively, and hence, are smaller in diameter than the farthings and-pence wheels II and I2. v

In order that the actuator IIIa may move laterally across the relatively large and small number wheels, the smaller of said wheels, I3, III and I5 are mounted upon a common horizontal shaft I6 (Figs. 2, 4 and 6) having its opposite ends secured in one side plate 2 and in a bracket II located between'and parallel with the side frames 2, and supported on the tie rods 3. The large number wheels II and I 2 are likewise mounted upon a common horizontal shaft I8 suitably secured at its opposite `ends in the other side frame plate 2 and said bracket Il, but the shafts I6 and I8 are relatively staggered or offset axially to locate the latter below the former, or in other words the large and small number wheels are eccentrically mounted with respect to each other sufficiently to present their teeth in horizontal alignment at the point where they mesh with the teeth of the actuator Ia.

The indicating wheels 5 and number wheels I I, I2, I3, I4 and I5, respectively, of corresponding denominational orders are geared together by gear trains, each including a driving gear I9 suitably secured concentrically to one side of the number wheel, a driven gear suitably secured concentrically to one side of the indicating wheel, and an intermediate idler gear 2l. The gears I9, 20 and 2I in each gear train are designed to effect a one to one ratio of drive between the number wheel and the value indicating wheel. Preferably in each train they are of the same relative diameter. In the case of the farthings and pence wheels 5 and 6 and associated number Wheels II and I2, the gears in each train are of the same relative diameter, but of larger diameter than the gears in the other trains, and the idlers 2| are eccentrically mounted relatively to the idlers in said other trains, as shown at 22 in Figure 5 This as will be understood, is because of the larger diameter of the number wheels II and I2.

At 23 (Fig. 3) is shown a comb plate for locking the actuator II)a in location, and 24 indicates the number Wheel locating devices, while 25 indicates a part of a clear signal mechanism, all forming part of the equipment of this type of register, as shown in my Patents Nos. 1,576,961 and 1,505,384, and which need merely be identified in passing.

Co-operating with the number wheels II to I5 is a two way transfer or carrying mechanism similar to that of my Patent No. 1,576,961 but modified, as follows, to adapt it to the different operating requirements in the present instance. Mounted below the shillings and pounds number wheels I 3, I 4 and I5 is a series of transfer heads 26 (Fig. 3), individual to said wheels, and adapted to rock from a central normal position` in opposite directions, respectively, about aL common axis on a fixed horizontal shaft 2l, the latter suitably mounted at its ends in one side frame plate 2 and the beforementioned bracket I'I. Below the farthings wheel II (Fig. 2) is a. similar transfer head 28 mounted on a horizontal shaft 29, the ends of which are secured in the other side plate 2 and the intermediate bracket I'I, the shaft 29 being staggered (as shown in Fig. 2) ,to locate it below the shaft 2'I in correspondence with the staggered relation of the shafts I6 and I8. Pivoted below the transfer heads 26 and 28, as at 30v (Fig. 2) are individual head operating levers 3l urged in the direction of the axis of the heads by motor springs 32. Associated operating levers .and transfer heads are connected by a link 33 pivoted to its head'below the axis thereof, as at 34, and to its operating lever, as at 35, so that in the central normal position of thetransfer head,

said link and head assume a toggle-locked relation resisting the urge of the motor spring. These kof the tripped head is continued by the motor spring 32 as will be clear, and one or the other of a pair of combined carrying dogs and stops 38 are thereby engaged with the number wheel of next higher denominational order to move it one 'increment or step.

The farthings, pence and pounds number wheels II, I3, I 4 and I5, respectively, are provided with widened teeth (Figs. 4, 5 and 6) which, when said wheels have been rotated a number of increments, or steps, corresponding to the limits of their denominational values, engage trip members 39 on the transfer heads 26 and 28 to effect the tripping operation. In the case of the farthings wheel II, three such teeth 40 are provided for tripping the transfer head 26 at every fourth step of movement of said farthings wheel, it being understood, of course, that the limit of denominational value in this instance is four. The pence wheel I2", in which denomination the limit of value is I2 is provided with a single laterally extendinglug III (Fig. 6) for tripping a transfer head 26 associated with the units of shillings number wheel I 3 and which, because of the relatively widespacing of the number wheels in these two orders, is equipped with a trip member 152 projecting laterally into the path of said lug 4I. The units of shillings wheel I3 and the pounds wheels I5 are each provided with a single widened tooth 43 (Fig. 3) the limit of denominational value being I0 in each of these denominations. In the case of the tens of shillings, wheel I 4, every other tooth islwidened, as at 94 (Figs. 4 and 6) so that the associated transfer head 26 is tripped at every other step or degree of movement. of said wheel -for a reason which will be understood.

At 45 is shown a transfer restoring bail, and at 46, a part of bail operating mechanism which form a part of the transfer restoring mechanism disclosed in detail in my co-pending-application Serial No. 505,906 filed December 31, 1930 and which have merely been included in the present showing in order to provide a complete dis-` closure of a register of the type with which my invention is concerned. Y

One of the aims of this invention is the provision of a set of visible indicating wheels, all of like diameter and journaled on a rectilinear axis for registering non-decimal as well as decimal amounts, an advantage being that'no one of the wheels is more prominently displayer than another. l

Also it is necessary in accumulating non-decimal amounts on a machine, the master actuator andthe totalizer of which are relatively shiftable laterally, that the differential actuator be able to engagewith any of the receiving wheels, during such relative movement.

Due to the character of the computation, however, that is, the different notational systems which must be taken into consideration in buildinga totalizer capable of decimal and non-decimal accumulation, and bearing in mind the differences in the pitch diameters of the totalizer wheels to obtain the necessary variations in the numbers of teeth on the respective decimal and non-decimal totalizer wheels, the present invention is thought to aord a solution both simple to manufacture, and operate.

The foregoing constitutes a detailed disclosure of a preferred embodiment of my invention, but it is to be understood that right is herein reserved to such modiiications thereof as fall fairly within the scope of the protection prayed.

1. In a calculating machine, the combination with a master actuator; of a totalizer for accumulating decimal and non-decimal items, the denominational wheels of which are arranged in sets, the wheels of one set being of diierent diable laterally to effect the engagement of the master actuator and successive wheels of the totalizer; axial supports for the respective sets of totalizer wheels in end to end eccentric relation, and so arranged that the peripheries of the totalizer wheels of less diameter lie flush with the peripheries ofthe totalizer wheels 'of larger diameter along a horizontal line defined by the points of engagement of the master actuator and all the totalizer wheels; a set of visible, denominational indicating wheels all of like diameter; a rectilinear axis on which all the indicating wheels are journaled; pinions fast with the respective indicating wheels the pinions on the indicating wheels corresponding with the actuator-driven wheels of one set varying in diameter from the pinions on the indicating wheels associated with tlie actu'iltr-drivn wheels'of another set; and similarly variant sets of transmission wheels intermediate and connecting 'the denominational pinions and their corresponding denominational totalizer wheels; and oneofthe sets of intermediate transmission wheels being eccentrically mounted relatively to another, corresponding with the eccentric mounting. of 'the sets of totalizer wheels with which they respectively engage, the denominational indicating wheel pinions and their transmission gears being of diameters corresponding with the diameters of the denominational totalizer wheels with which they are respectively in train.
