Patented Aug. 23, 1932 UNITED STA ES PATENT 1 OFFICE FREDERICK L. FULLER, OF ILIoR, NEwYoRx, ssn-110R, BY MEsNE ASSIGNMENTS, To THE NATIONAL cAsrt REGISTER COMPANY, or DAYTON, oHIo, A CORPORATION OF MARYLAND cAsIr EGISTER 'Application filed December 22, 1922. Serial No. 608,467.

This invention relates to improvements'in cash registers or accounting machines and the totalizers employed therein and more particularly to the transfer or carrying Abroad object of the present invention is to provide a suitable mechanism for positively transmitting motion from each adding wheel of a lower order to the adding wheel of next higher order when the lower order adding wheel has completed a full rotation.

More specifically it is an object of the present invention to provide a transfer mechanism comprising a trip pawl actuated by a trip, device associated with the wheel of the lower'order to set a transfer'pawl in its transfer position, so that when a separately operated arm is oscillated during a regular operation of the machine the transfer pawl describes a path which intercepts a tooth of the next higher order totalizer wheel thereby effecting a transfer.

Further objects of the present invention are to prevent accidental displacement of the totalizer wheels when out of engagement with their actuating segments, to provide fric-' tional means for retaining the components of the transfer mechanism in their set position and to preclude the possibility ofover-carrying of the totalizer Wheel when the machine is subjected to improper usage.

lVith these and incidental objects in view the invention consistsin certain novel features of construction and combination of parts, the essential elements of which'are set forth in appended claims, and a preferred form of embodiment of which is hereafter described with reference to the drawings which accompany and form part of the specification. I 1

v In the accompanying drawings the improvements are shown in connection with a machine of the general type fully shown in the pending applications for United States Letters Patent S. N. 263,125, filed November 19, 1918, and S. N. 283,720 filed Mar. 20, 1919, by Frederick L. Fuller as well as in the British Patents 135,465; 140,363; 157,823; 157,824; 157,825, of July 11, 1921. Only such parts of themachine as are directly involved in the present invention are described herein, however, and reference should be madeto the applications and British Patents mentioned for any information desired as to the construction and operation of the rest of the machine.

Although the improvements have been shown applied to the machines shown and described in the above cited applications and patents, it is to be understood that the improvements are capable of being applied to or embodied in accounting machines 1 generally without departing from the spirit of the invention.

Described in general terms the illustrative machine comprises a series of manipulative devices such as keysv 20 operable to actuate totalizing mechanism and mechanism for entering the items on a record strip.

The keys 20 are pivoted upon a rod 21 and resting upon the rear ends of the keys is a key coupler 22 pivoted at 23. When the outer ends of the keys are depressed the coupler is rocked clockwise about its pivot and its nose 24 enters the notches 25 in the rear ends of the keys. The construction and purpose of key coupler mechanisms are well known in the art and need not be discussed herein.

As shown in Fig. 1, each key 20 is formed with an upwardly extending arm 26 carrying a stud 2 7 engaging a slot 28 in a plate 29 rigidly mounted in a frame 30 loosely mounted on the shaft 31. The slots 28 in plates 29 are graduated so that each of the keys will impart a different degree of movement to the frame 30. The plates are furthermore provided with a 'cuate slots 36 to permit the upward tilting of the cam plates without interfering with the rollers on the remaining unoperated keys. Secured to the frame 30 is a segmental rack 301. It is to be understood that the keys 20 are arranged. in banks and that for each bank there is a differentially actuated frame 30 and its corresponding segment rack. Each segment is always in mesh with a pinion rigid with its corresponding item type wheel 32 and sets up number which corresponds to the value of the key depressed.

Mounted below the item type carriers and operable by the segmental racks herein before mentioned two totalizers and 34, designated as totalizers A and B in Fig. 1 of the drawings. These may be utilized for the purpose of registering amounts for separate departments or clerks or in any other manner where it is desired to segregate the transactions into two classes and they have manipulative means associated therewith in order that either totalizer may be operated to register amounts of the various transactions.

Connected to the key coupler is a double rack 841, the connection being such that as the coupler is rocked by the keys therack is raised or lowered, and drives a shaft 35 in such a manner that a complete reciprocation of the coupler will effect a complete rotation of the shaft. The shaft '35 carries cams and other devices for operating various parts of the mechanism. The mechanism for effectingrotation of the shaft has not been shown or described in detail because it is so old and well known in the art.

In the Fuller application No. 283,720 and British Patent 140,363 there are shown two special keys which are d signated as Clerks or Coupler lifting keys (not shown in this application). These keys have certain functions, one of which is to serve as a means whereby the key coupler 22 may be partially raised to what may be termed the coupling position, in which position other keys representing the nature and amountof the transaction may he engaged with the coupler so that a complete operation of all the keys so engaged with the coupler may be effectedfurther by pressure applied to any engaged key. For further information relative to this construction reference may be had to the Fuller application just mentioned.

As shown more fully in the U. S. appli cation S. N. 263,125 and the British patents previously mentioned the totalizers A and B are pivotally mounted between side frames so that'their pinions are capable of being rocked into engagement with their respective actuators. The engagement of the totalizer A with its actuator is under control of its corresponding Clerks or Coupler lifting key A while the totalizcr B is placed in operation by means under control of its associated Clerks or Coupler lifting key B. The engagement of the totalizer pinions with their associated actuators is effected during the time that the Clerks or Con 3101' lifting key is depressed to its coupling position. Other keys may now be engaged with the coupler and upon further depressing one or more of such other keys the pinions will be actuated an amount commensurate with the value of the key or keys depressed. At the extreme end of the downward stroke, or, if desired, during the first part of the upward stroke of the keys, the selected totalizer is disengaged from the actuators and re mains disengaged during the time the keys are returned to their normal position. This mechanism has been briefly explained here in order to understand more fully the present invention. However, for a more detailed description and showing reference may be had to application S. N. 263,125 and the several British patents.

The totalizers which are actuated during item entering operations are alike in all respects and a description of one totalizer will suffice. Referring to Fig. 2 the totalizer is mounted in a frame 40 formed with ears 41 and 42 supporting a shaft 43. Each totalizer wheel 44, to which is attached its associated totalizer pinion 45 and transfer disc 46, is loosely mounted upon this shaft. Below and parallel to the shaft just mentioned is a second shaft 47. This shaft carries the various devices for effecting transfers which will be explained more in detail hereinafter. In alignment with the shaft 47 are two bearings 48 and 49 which are adapted to receive studs carried by the side frames so that the totalizer frame may be oscillated bodily about the studs to move the totalizer wheels into or out of engagement with the actuating segments.

In the particular illustrative embodiment the totalizer comprises seven adding wheels 44 but this number may be altered to meetthe requirements of a particular registering capacity. The adding wheels 44 and attached parts are practically duplicates and a description of one will suffice for all.

is moved during an item entering" operation so that it passesfrom its nine to its zero po-' sition, a. unit must betranSferredfrOm the units to thevtens wheel in order that the adding wheels will indicate the true amount.

, In general, provision must be made to transmechanism will have passed from the mit a unit toany higher denominational order each time'that the next lower denominational order adding wheel passes from its nine to its zero position. At times it is necessary to effect transfers by transfers, and to make the problem clearer assume that 923 stands on the totalizer and 79 is to be added. At the end of the operation the totalizer wheels should, of course, indicate the total 1002. Theunits pinion duringthe opera tion will bemoved nine steps by its actuator through 0 to its 2 position and, of course, a unit should be carried to the tens wheel. The tens vpinionyhowever, by the movement of its actuator and the carrying 2 position to its 0 position and it will be necessary to carry a unit to the hundreds totalizer wheel, and in the same'manner since the hundred totalizer wheel now stands at 07, a unit must he transferred to the thousands totalizer wheel in order to represent the correct total. In the'presentembodiment, if one should be transferred to a wheel of the next higher order while the same wheel is simultaneouslybeing actuated by the actuators, a unit would be lost. and an incorrect total would result. For this reason it is necessary that transfers beeflected upon the upstroke of the keys, that is, when the totalizers pinions are out of mesh with the actuators. Furthermore, in order to eflect transfers by transfers it is necessary to actuate the transfer mechanism successively, first the transfer mechanismbetween the units and tens order, then the transfer mechanism between the tens and hundreds order, etc. i v. H

With the above in mind, the method of effecting transfers between successive orders will now be explained. The mechanisms for effecting transfers between successive denominational orders are alike and in view of thisfact the transfer mechanism between the units andtens order only will be described.

As stated before, each totalizer wheel 44 (Fig. 4) has attached to it at one side a transfer disk 46 which carries a trip tooth 50. Pivoted upon the shaft 47 is a trip pawl 51 (Figs. 2, 4 and 9) which is provided with a, trip tooth 52 in the line of travel of the trip tooth 50'and adapted to. engage therewith as the totalizer wheel passes from its 9 to its 0 5 position. The trip pawl 51 is further protrip pawl 51 is warm vided with a forward extension 53 carrying a stud 54 and a downwardly extending lug 55, the purpose of which will be explained later. Mounted on the shaft 47 and adjacent to the cated during each operation of the machine. The arm 56 has a forward extension 58 which carries a transfer pawl 59 carrying a transfer tooth 60 in the plane of the totalizer pinion 45 of the next higher denominational order, and will engage at times one of the teeth of the pinion to advance the totalizer pinion a unit when transfers are'to be effected. As

shown in Figs. 2, 4 and 9, the stud 54 which is secured to the trip pawl 51 passes through a clearance slot 61 formed in the forward extension 58 of the arm '56 and registers with a slot 62 in the transfer pawl 59. a

The means for attaching the transfer pawl 59 to the arm 56 is clearly shown in Figs. 2 and 9. Referring to these figures there will be seen a stud 64 which passes through the arm 56 and the transfer pawl 59. Between the head of the stud and the side of the arm 56 is a spring cone washer 65., The reason for this construction is that when the arm 56 is held,the transfer pawl 59 may be given a movement independent of the arm and at times when the arm 56 is given a movement, sufficient friction will be maintained between the faces of the arm 56 and the pawl 59 to insure that the both will move simultaneously.

The arm 56 is provided with a rearward extension 66 co-operating with an open slot 67 formed in a transfer operating arm 68.- The transfer operating arms 68 are loosely mounted upon the shaft 31 and are provided with rearward extensions 69 (Figs. 1 and 3) carrying oppositely projecting anti-friction rollers 70 and 71. Upon the rotation shaft 35, which, as statedbefore, is given a complete rotation upon each operation of the machine, is secured a series of complementary cams 72 and 73 the peripheries of which are in contact with their associated anti-friction rollers. The pairs of cams 72 and 73 are spirally arranged about the shaft so that in a cycle of rotation of the shaft 35 the cams will actuate the transfer arms successively, first the tens transfer arm, then the hundreds, etc. It is, of course, necessary that a transfer arm be provided for each transfer device and in the illustrative embodiment six transfer arms are necessary; but it is evident that if the registering capacity of the totalizer be altered, a corresponding number of transfer arms must be provided.

The sequence of operations of the transfer devices is illustrated in Figs. 4, 5, 6 and 7, Fig. 4 showing the normal position of the totalizer. When a Clerks or Coupler lifting key is depressed to its coupling position the shaft 35' will be partiallyyrotated and the totalizer engaging mechanism brought into 56 which is reciprooperation so that the totalizer pinions are thrown into mesh with the segmental racks. Since the rollers 70 and 71 contact with the peripheriesof the cams which are substantially concentric with the shaft 35, no movement of the arm 68 will take place at this time.

The totalizer pinions are shown in engagement with the segmental racks in Fig. 5. If, for example, 9 has been standing upon the units totalizer wheel and l is to be added thereto, the segmental rack 301 will advance the units pinion wheel one step and in so doing the totalizcr wheel will pass from 9 to 0. The trip tooth of the units totalizer .vheel will now contact with the trip tooth of the trip pawl 51 and rock it counterclockwise as viewer in Fig. 5.

t ince the rollers are still in contact with the concent portion of the cams no movement of the arm 68 will take place and the arm 56 will be held in the position shown in 5 and as the trip tooth 50 depresses the trip tooth 52 of the trip pawl 51 the stud 54: will be carried upwardly, and by virtue of the pin and slot connection with the transfer pawl 59 will rotate the transfer pawl clockwise independently of the arm 56 about its pivot 64: until it occupies the position shown in Fi 5. The stud 54 in its upward movement will impart no movement to the arm 56 since it will merely play in the clear- 1111'; -ot 61 provided for that purpose. The trans.er pawl 59 is now in position for effect- 0 ing a transfer to the totalizer pinion of the next higher order.

N ear the extreme end of the down-stroke of the keys, or, if desired, during the first part of the tip-stroke the totalizer pinions are disengaged from their segmental racks. fies Fig. 6. The transfer operating arm 68 will hold the arm 56 and associated parts in the position shown in Fig. 5 while the totalizer is rocked bodily about the shaft 47 until it occupies the position shown in Fig. 6. At the proper time the roller 70 will engage the high portion 7a of the cam 73 to rock its associated transfer arm downwardly. As the transfer arm 68 begins its downward movement 7) the arm 56 will be rocked counter-cloclnvise and carry with it the transfer pawl 59 by the means previously described, and the trip pawl 51. Upon further descent of the transfer operating arm 63 the lug will contact with a portion of the totalizer frame and hold the stud 54 carried thereby against further movement. ig. 7.) As the transfer operating arm scends still further the forward extension 0 of the arm 56 will be raised still further it u rdly, rocking the transfer pawl 59 counter-clockwise about the then fixed pivot 54 as well as about its own floating pivot 64, the transfer tooth having in the meantime engaged one of the teeth of the totalizer pinion of the tens order to advance it one step. As the transfer operating arm 68 returns to its normal position the parts will again assume the position illustrated in Fig. 4. The dash dot line of Fig. 7 describes the path of the pawl 59 during the cycle of events just described.

Fig. 8 illustrates the condition which exists when a transfer by a transfer is to be effected. To make this clearer assume that the tens wheel has been standing in its nine position and one has been added to it by the transfer operation just described. It is necessary, of course, that a unit be added to the hundreds totalizer wheel. As a unit is being transferred to the tens totalizer wheel (Fig. 5) the totalizer pinion will advance from its nine to its zero position and in so doing will trip the pawl 51 associated with the transfer mechanism between the tens and hundreds totalizer wheel and set the transfer pawl 59 to perform a carrying operation. During the return or upstroke of the keys and after the transfer arm 68 associated with the transfer device between the units and tens order has been actuated, the transfer arm 68 associated with the transfer device between the tens and hundreds order will be actuated and advance the hundreds totalizer wheel one step in the 11121111191 previously'set forth.

To prevent accidental displacement of the totalizer pinions from their set positions when disengaged from their actuators as well as to assist in preventing over-rotation of the totalizer wheels due to momentum there is provided a series of pawls 80. (Figs. 1, 2, and 4.) The pawls 80 are loosely pivoted upon a shaft 83 and urged rearwardly by springs 81 so that their wedge shaped ends 82 engage the interdental space of the corresponding totalizer pinion.

Machines of this character are at time subjected to improper usage by persons who desire them to work improperly, and in order to effect a mis-operation of the machine they have operated the machine rapidly and with a considerable degree of force and violence. In rapid operations the sequence of events occur almost instantly and if considerable force was utilized in operating the machine the transfer mechanism might impart such a rapid rotation to the totalizer wheels so as to cause the totalizer to over-carry, with a result that an incorrect registration would be indicated. To preclude the possibility of over-carrying the following mechanism is employed.

This mechanism is best shown in Figs. 6, 7 and 9. The transfer pawl 59 above mentioned is provided with a camming projection 85 which is in alinement with the holding pawl 80 associated with the same totalizer pinion as the transfer pawl 59. From Fig. 7 it will be evident that if the transfer arm 68 was actuated rapidly the transfer tooth '60 would i part such a rapidrotation to the totalizer wheel as to over-carry. The camming projec tion 85 on the transfer pawl 59-is so positioned with relation to the rearward edge of the pawl 80, that at substantially the time the trip tooth 60 becomes disengaged from the teeth of the totalizer pinion theeammin projection 85 will contact with the rearwar edge of the pawl so that the upperend of the pawl 80 will be cammed rearwardly to force'- the wedge shaped'ends, 82 into co-operation with the inter-dental spaces of the pinion, thus positively stopping the movement of the totalizer pinion and preventing the possibility of over-throw. I

' Although the camming projeetion 85 has been shown in connection with the transfer pawl 59 with minor changes itcan be formed upon the rearward extension 58 of the arm 56 to accomplish the same purpose, 1

From the foregoingv description it will be evident that during each operationjof themachine thetransfer pawls 59" are actuated by their associated transfer operating arms irrespective of whether transfers are to be effected. When no transfers are to take place therearward end of the arm 56 will-be rocked downwardly about the shaft 47 as a pivot and the transfertooth 60 will be carried rearwardly but will not engage the teeth of the pinion wheel. The circular path described by the transfer tooth 60 of pawl 59 during a nontransferring cycle is shown by the dash dot line 6010f Fig. 4;

IAny suitable mechanism may be'provided for resetting the, totalizer pinions to zero, such as for example that shown. in the Fuller application S. N; 263,125 and the British patents. j p a 'm Although this type of transfer mechanism has beenshown in connection with a cash register it is not the desire to confine its applica-1 tion to this particular type of machine as it is readily evidentthat with minor'changes it may be applied to other forms of cash registers, accounting machines and other devices.
