25 Claims.

My invention relates to calculating mechanisms and more particularly, to improvements in col- .umn registers, so called, for writing-adding machines of the well known Elliott-Fisher type.

In my co-pending application, Serial No. 505,- 905, filed December 31, 1930, I have disclosed a decimal item, or sub-total column register, for such machines, embodying transfer restoring mechanism adapted for automatic operation, and zero-setting mechanism adapted for manual operation, said mechanisms being operatively related so that the transfer restoring mechanism will be operated as an initial function of the zerosetting mechanism to restore any transfer elements which may be out ofvnormal position, and as a final function of the zero-setting mechanism, to restore any transfer elements which may have been thrown out of normal position during the zero-setting operation.

The object of my presentinvention, generally stated, is to provide a column register equipped with sets of denominational value-indicating and number wheels respectively, arranged, as in my co-pending application, Serial No. 532,813, filed April 25, 1931, for a system of adding wherein the limits of denominational values are diierent in certain orders, for instance, as in the English currency system, equipped with transfer, zerosetting, and transfer restoring mechanisms, respectively, of the type of my aforesaid application, Serial No. 505,905, but co-operatively related to meet the different operating requirements arising in the use of the dierent arrangement of the sets of value-indicating land number wheels.

The invention is conveniently illustrated as applied to a. combined typewriter and calculating mechanism, of the Elliott-Fisher type, equipped with one or more column registers mounted upon a register bar. These registers, as a type, include a series of value-indicating wheels of successively higher denominational order, and a similar series of toothednumber wheels for ro tating said indicating wheels. The number wheels are rotated by a toothed actuator ,laterally mov-- in said bar to accurately nx the register in posi tion, and the usual casing l encloses the'adding mechanism. A series of aligned value-indicating wheels oi' like diameter, including a farthlngs wheel I (Fig. 3), a pence wheel l. units and tens of shillings wheels Il and II, respectively, and a group of pounds wheels I2, all arranged in successively higher denominational order, are journaled on a shaft I mounted at its vopposite ends in the opposite side walls of the casing I. Buitably delineated on the periphery of each indicating wheel, for observation through the sight opening I3, (Pig. 1), are equidistantly spaced digits I4 (Figs. 3 and 17). The farthings wheel l is provided with three series of such digits, each series including 1", "2 and 3 followed by 0, the pence wheel 8 bears the digits "l" to "11" followed by the units of shillings wheel Iii bears the digits l to ,9 followed by 0", while the tens of shillings wheel I'I bears five series of digits, each including 1 and 0", alternately and the pounds wheels I2 bear the usual digits The number wheels I5 (Figs. 1 4) arranged in :orresponding series with the value-indicating wheels, each drive a related value-indicating wheel, in a one-to-one ratio, through a driving gear I8 iixed to the number wheel, an intermediate gear Il, and a driven gear I1 fixed to the value-indicating wheel. The usual detent and locating rollers I9 cooperate with the number wheels I8 in a manner which will be obvious.

The toothed master wheel rotates through iixed uniform steps or increments of movement, whereas, certain of the number wheels, as the farthings and pence wheels 8 and 9 must advance by increments or steps of different lengths from those through which the shillings and pounds wheels Il, Il and I2 advance, the former having twelve step, and the latter ten step cycles of movement. Hence, the number wheels I5 of shillings and pounds denominations are lprovided with ten teeth and those of the farthings and pence denomination with twelve teeth. The latter wheels are necessarily larger, since the teeth on all the number wheels are equidistantly spaced. In order that the master wheel 20 may move in s straight path across said number wheels, those of the shillings and pounds denominations are mounted for individual rotation upon one shaft 2I (Figs. 1,4, 5 and 15) and those of the farthings and pence denominations are journaled upon a separate shaft 22, the shafts being staggered or offset in end to end relation, to align the teeth of all the number wheels at the point of meshing with said master wheel 2li. The shafts 2i and 22 are suitably journaled at their outer ends in the side walls of the casing 6 and at their inner ends in a partition plate 28 located between and Parallel with the side walls of the casing.

Associated with the respective denominational number wheels Il are individual transfer deaosaise vices, as follows:-Peripherally spaced from said Vnumber'wheels in a series -of rocking 4'transfer heads 24 one for each number wheel except that of the pounds of the highest order denomination. The heads 24 for the number wheels Il of shillings and pounds denominations on the one hand, and ,the head 24 for the number wheel I l of pence denomination on the other, are freely mounted upon the shafts 2l and 2l, respectively, the outer ends of which shafts are fixed in any suitable manner in the opposite side wallsof the casing t in relatively staggered or off-set relation to compensate for the staggered relation of shafts 2| and 22 and the diii'erence in'diameter between the number wheels It, the inner ends of the shafts 2l and 28 being correspondingly oi!- set and supported by the partition plate 23, as shown in Fig. 2. Unitary transfer and check dogs 21 and 2l, respectively, (Figs. 1, 13 and li),v

are pivoted on each head, as at 29, to rotate the number wheel I5 of next higher order and its connected train, one step when said heads are rocked to a proper extent, and to then lock said wheels and heads against farther transferring or carrying movement. Springs 2l yieldingly maintain the dogs effective.

Associated with the transfer heads 24 are individual motor springs II (Fig. 1) connected to their associated heads to rock the same through individual operating mechanisms each including a bell crank lever member 22 pivoted at 23 in a mounting 24, so that one end of the bell crank is normally urged in the direction of the axis of its head 24. A connecting link it between each associated head and operating lever, is pivoted to the head, as at 36, and to the operating lever, as at 21, to assume, in the normal position of the parts, a dead center position relatively to the axis of the head, thereby providing for a toggle lock relation of the parts to maintain the motor in tensioned condition.

The depending arms of the operating levers 22 intersect the links 35 at intermediate points I1 in the lengths of the links, at which points the levers and links are pivotaliy connected, the free ends 3l, It of the operating levers 32 extending past the links, as shown in Fig. l.

Springs 42 press the recessed arms of individual detents 4I pivoted on the mounting 34, against rolls 4t journaled in the rearwardly projecting ends of the links I5 to releasably maintain the links and heads 24 in dead center or straightened toggle link positions.

The respective transfer heads 24 are tripped from their normal dead center positions to enable the transferring operations to take place, by the contact of a widened transfer tooth 4I on each of the corresponding number wheels I5, except that of the pence denomination, with a trip member 44 on the associated head 24 projecting into the path of its transfer tooth 4l. A projecting tripping lug 45 (Fig. 9),V on the pence number wheel I5 is adapted to contact a laterally projecting trip member 44, (Figs. 2 and 13 to l5), on its corresponding head, because of the customary wide spacing of the number wheels I5 provided at this point to facilitate reading the register. As will be understood the tripping operation is effected, in each instance, by a number wheel of next lower denominational order during the step of movement oi' the value-registering wheels t--I2 to zero registering position.

The present register is designed for adding only and therefore for one-way transfer operations. Hence, means are provided to prevent breaking than the proper direction comprising arearwardly projecting stop arm 48, ,(Fig. l), on each of the operating levers 22, which storarms Voverliethe rollers 40, in the normal positions of the links 25, and prevent movement of the links and related parts in the subtracting direction.

'I'he transfer restoring mechanism includes a restoring bail 41, (Figs. 1 and 2) and bail rod 4l, pivoted coaxially with the operating levers 22 and arranged to contact the free ends 2B, 2l' of said levers and restore the latter and associated parts to normal position after a Y transferring operation. Normally. the bail rod 48 lies at a point remote from the projecting ends 2l, 2l' of the operating levers 32, to afford the projecting ends sufficient travel in clockwise direction to enable the operating levers 22'to complete their transferring or carrying operations, the projecting ends 28, 28' at the completion of the transferring operations then lying adjacent the bail rod 48, as shown in Fig. 6.

It then becomes necessary to reset the tripped transfer or carrying mechanisms to their normal cocked positions.

The carry restoring bail 41, 4I is pressed against the projecting ends 2B, 28' of the tripped operating levers 32 to return the levers to their normal positions, and straighten the toggles 24, 25, as follows: A restoring rack 49, (Figs. 1, 3 and 6), is slidably mounted for back and forth movement on the base of the register, the forward end of the restoring rack normally protruding beyond the front of the register into the path of a cam (not shown) on the carriage of the machine in a manner well known in the art, to rock the restoring ball 41, 48 counter-clockwise through a toothed pinion 50 meshed with the rack and rotatable on a fixed stud 5|, a toothed sector 52 meshing with the pinion and rocking upon a cross rod 53, and a bail operator 54 journaled on the cross rod 52, and operated by the sector 52 through a yielding safety connection 55` A spring 56 having its opposite ends connected to a fixed stud 51 and to the sector 52, respectively, returns the transfer restoring mechanism to normal position, a lug 55 on the sector 52 picking up the bail operator 54 as will be clear.

Coming now to the zero-setting mechanism, in .my co-pending application, Serial No. 505,905,

before mentioned, the number wheels are set to zero by a simple eiiicient mechanism for rotating the number wheel shaft a complete cycle of movement and for picking up said wheels by said shaft. In my present invention, the zero-setting mechanism operates on the same basic principle, but is modified to meet the different operating requirements of the present register.

Mounted upon a suitably located stud 59 (Figs. 1 and 12) on the casing 5 is a zero-setting lever 50 adapted to rock from and'towards its normal idle position at its clockwise limit of travel. Fast upon one end of the number wheel shaft 2| is Aa toothed pinion 6| mhing with an arcuate exnumber wheel shafts 2| and 22 are identical toothed pinions 04 and ll, respectively, (Figs. 3

and 13 to 16), relatively off-set and geared together by a suitably mounted idler pinion 44 of sumcient width to mesh with both pinions 84 and lment of the zero-setting segment 82. to pick up pawls l! (Fig. 18) on all number wheels l5 reg' istering other than zero and advance the wheels in adding direction to their zero registering positions as said shafts are rotated through a complete cycle of movement clockwise. As will be clear, rotation of the number wheel shafts 2| and 22 in counter-clockwise direction by retraction of said segment t2 is idle with respect to the number wheels I5.

Since, as previously explained, the transfer devices, when tripped, lock the number wheels I5 against rotation after a transfer operation, it will be evident that an initial operation of the transfer restoring mechanism must be effected to restore to normal position any transfer devices which have been operated, as a condition precedent to a zero-setting operation. Also since the number wheels i5 trip all the transfer devices during their increment of movement to their zero registering positions, it follows that a iinalftransfer restoring operation must be effected to reset the tripped transfer devices and thus unlock said wheels after the wheels have reached their zero positions. To this end, the zero-setting lever 60 is provided with a cam 10, (Figs. 1, 6 and 12) cooperating with a hooked rocker 1I pivoted at one end, at 12, to the adjacent side wall of the casing 6, the opposite free end of the rocker lying in contact with a stud 52 on the carry-restoring sector 52, to operate the sector 52, and hence the transfer restoring mechanism, upon initial advance and again upon the initial retraction of the zero-setting lever 60. A pin and slot connection 13 and 14, respectively, between the zerosetting lever Bland its segment 62 permits the lever suillcient idle or independent advance and retraction relatively to its segment, to provide for operation of the transfer restoring mechanism prior to both the advance and the retraction of the segment 62.

` In the invention disclosed in my co-pending application, Serial No. 505,905, heretofore mentioned, it is immaterial whether or not the cam forming the toe of the zero-setting lever releases the rocker immediately after its initial operation of the transfer restoring mechanism at the outset of the counter-clockwise travel of the lever, which resets the tripped carrying devices, as .the number wheels are each equipped with but a single carry-tripping tooth, and it is only necessary to insure the withdrawal of the tripped carrying devices, if any there be, prior to the advance of the number wheels in a zero-setting operation.

Failure to reset all tripped carrying devices prior to zero-setting operation, would enable such tripped carrying devices to maintain their wheels locked, and hence, prevent a 4zero-setting operation.

In the present invention, however, certain of the number wheels, as the farthings and the tens- -of-shillings wheels, (Figs. 8 and 10) are equipped with a plurality of carry-tripping teeth 43, the farthings wheel in the illustration having three equidistantly spaced carry-tripping teeth, and the tens-of-ahillings wheel having dve equidistantly spaced carry-tripping teeth.

It is, therefore, necelary. al heretofore statvi to modify the mechanism disclosed in application, lerlal No. 506,905. in certain important particulars. to ei'fect a rapid withdrawal of those carrying devices associated with thesnumber wheels, 'as the farthings and tens-of-shillings wheels, having a plurality of carry-tripping teeth. Buch withdrawal should also be effected earlier in the carry-restoring Operation than the withdrawal vof the comin! devices associated with those number wheels equipped with but a-single carry-tripping tooth, since the aero-setting operation follows the carry-restoring operation so quickly that one of the carry-tripping teeth on the tensof-shlllings wheel. for instance, might contact the tooth M on its carrying head 2l before the latter is completely withdrawn from its path.

Furthermore. and fully as important, is the necessity for retaining in an over-restored position. those carrying heads associated with the number wheels equipped with a plurality of carrytripping teeth 4I, to prevent such carry-tripping teeth from tripping their carrying devices immediately after the restoration of such devices,

and prior to the point in the zero-setting operation when all the carrying devices are to be tripped as-the number wheels pass from their 9", or equivalent positions, to their 0 positions.

And I contrive to obtain these differences in operation with but slightl mechanical changes in the structure shown inthe co-pending application, Serial No. 505.905, which, nevertheless, result in considerable variation in operation.

To eifect the. rapid and early restoration of those tripped carrying devices which are associated with the number wheels having a plurality of carry-tripping teeth, as the farthings. and tens-of-shillings wheels. I preferably forwardly off-set the depending free ends Il (Fig. 1) of the operating Ylevers 82 associated with such carrying devices, so that when tripped, the free ends Il will lie closer to the carry restoring bail 48 common to all the carrying devices, than do the free ends 38 of those carrying devices associated with number wheels equipped with but a single carry tripping tooth It. It is obvious that, because of this arrangement. the carry-restoring bail 4l, when operated by the cam 1l of the zerosetting lever, and the rocker 1l, will pick up the off-set ends II first and start the withdrawal of their associated carrying devices before the bail can operate upon the free ends 3l of the remaining carrying devices, thus imparting a lead to the carrying devices equipped with such forwardly off-set ends 3l'.

As a result of olf-setting the ends Il', their associated carrying devices will be -withdrawn from their number wheels more suddenly and to a greater distance than are the remaining carrying devices, to accommodate which over-restoring travel of the special carrying devices, I prei'- erably provide such carrying devices with twopart carrying heads 1l, "Il, (Figs. 19 to 21,) as distinguished from the single-part or integral construction of the carrying heads 24 appropriate to the remaining carrying devices.

The two-part carrying heads each includes a bearing member 'l5 similar to the carrying heads 24, except for the omission of the tripping tooth M and journaled on the pivot shafts 2l. (2l). A combined transfer and check dog 21, Il is pivoted on the bearing member. the tail of which man l doglsnormallyheldagainstthsedgsofths mringilwhichmaintains tactof therearend ofthesiot llinthetripmember, against the pivot shaft 2l (Il), so as to introduce the tripping tooth u of the slidable trip member Il into the path of the tripping teeth of the number wheel.

Obviously, the over-restoring throw imparted to the particular carrying devices, because of the olf-set ends Il' of their operating levers is permitted by the slots 1l in the slidable trip members 'Il to which the links Il are pivotally connected, which permits these toggle structin'es, after restoration to their straightened positions. to be slid farther axially to withdraw their tripping teeth Il completely out of the path of the number wheel teeth u, as well asin rocking their detenta Il farther in counter-clockwise direction than the detents 4l 'appertinent to the one-piece carrying heads 2l.

During such over-restoring throw of the carrying devices equipped with the two part carrying heads, the trip members 1l slide rearwardly relatively to the bearing members 1l, and further tension the springs Il.

In case the carrying devices were in their set or cocked positions at the beginning of a zerosetting operation, the transfer restoring bar ll would not materially aiIect those having the usual form of head 24, but would rock rearwardly the olf-set ends II of the operating levers associated with the two-part heads 1I, 1l, and withdraw the tripping teeth u thereof to idle position.

As heretofore stated, however, it also is necessary to maintain the tripping teeth u of the slidable trip members 18 in such completely withdrawn positions until the number wheels with which the unmodified carrying devices oo-act. have nearly completed their advance to their zero positions.

To eectvthis result. I have altered the shape of the 'cam lll at the toe of the zero-setting lever 80, and have somewhat lengthened such cam, as compared with the corresponding cam .shown in my copending application, Serial No. 505,905, so that the cam will maintain its control of the rocker Il and hence, the transfer restoring mechanism. to hold the latter in effective position durne limit of its travel. 11 formed ing almost the entire counter-clockwise or resetwhereupon the spring 56 (Fig. 1) quickly returns the transfer-restoring mechanism to its normal position, the rocker ll being swung clockwise so that its roll 'l0' rides along the more abrupt front face of the cam 10.

Simultaneously. the operating lever springs Il `and the detent springs l2 associated with those carrying devices having two-part heads 15, 1l, advance their 'respective carrying devices to their normal cocked positions. during which advance. the trip members" slide forwardly along the ways 'l1 in the bearing members 1l, until arrested by contact of the rear end walls of their slots 18 with the pivot shafts 25 (26).

The carrying devices of all the number wheels are now in position to be tripped by the tripping teeth 43 pf their respective number wheels l5, as the wheels pass from their 9 or equivalent positions to their zero positions. it being borne in mind that the number wheels are still being advanced by the zero-setting lever 60.

The ensuing carrying operation of all the carrying devices to advance their respective number wheels one step, however, has no objectionable effect on the number wheels, as the latter are being advanced simultaneously by the zero-setting lever 60 through the zero-resetting segment 62,

so that the number wheels arrive in their zero positions under the combined influence of their carrying devices and of the zero-setting lever, the check dogs 28 of the carrying devices at the end of their carrying movements, operating to lock the number wheels against farther advance, and hence, against overthrow due to a violent operation of the zero-setting lever 60.

Returning to the start of the zero-setting operation, it will be understood that the slot 14 (Figs. 1, 6 and 12) in the zero-setting segment B2 is of sufilcient length to enable the zerosetting lever 60 to actuate the transfer restoring mechanism and withdraw the tripped carrying devices, if any, from the number wheels l5 before the stud 13 of the zero-setting lever advances the zero-setting segment from its normal idle position.

The zero-setting segment, when rocked by the zero-setting lever on its counter-clockwise travel, turns the spur gear 6l and the oiI-set shafts 2l and 22 clockwise, the grooves 61, 68 of the shafts picking up in their advance the variously positioned number wheels I5 to turn the number wheels in adding direction until their zeros appear at the sight opening I3.l

As the numeral wheels l5, at this time still under the influence of the zero-setting lever, ad- Vance towards their zero positions, the tripping teeth 43 of the wheels wipe past the tripping teeth 44 of the set carrying devices and trip the latter as heretofore stated. The carrying devices operate relatively to their numeral wheels in just the same manner as when a transfer operation is effected during an adding operation, but with this difference.

In an adding operation, the digits of the item being entered, are registered denomination by denomination successively, so that when the addition of a digit on the particular numeral wheel i5 at that time engaged with the master actuator 20, trips the associated carrying device, such device immediately operates on the numeral wheel of next higher order, which .last named wheel at that time is stationary, as are all the other numeral wheels, except the particular wheel engaged with the master actuator.

If such numeral wheel of next higher order was also turning at the time the carrying operation occurred, the carry would be los or swallowed.

That is precisely the condition of which I take advantage in clearing operations, since all the numeral wheels I5 are rotating forwardly under the action of the zero-setting lever 60 and its segment 62 from 9 (or its equivalent) to "0 at the same time that all the carrying devices are tripped, and hence, although the carrying devices perform their usual carryingl operations, such operations are futile and the carries are lost or swallowed.

As a result, the numeral wheels i5 remain at their zero positions at the end .of the counterclockwise throw of 'the zero-setting lever 60 and segment 62, unaffected by the carrying action of the carrying devices.

'Ihe operator now returns the zero-setting lever 60 in clockwise direction to its normal position. Initially, the zero-resetting lever 60 moves clockwise relatively to the resetting segment 62, due to the slot and pin connections 13, 14, the abrupt front face of the cam at the toe of the zerosetting lever, wiping against the roll l0 on the hooked rocker 1| to shift the free end of the rocker counter-clockwise against the stud 52' on the carry-resetting sector 52 and rock the sector clockwise to restore the carrying devices, all of which were tripped as the numeral wheels passed from their 9" (or equivalent) positions to their zero positions.

Continued return movement of the zero-setting lever 60 causes its stud 13, after its initial idle movement, to pick up the zero-setting rack 62 and restore it to its normal raised position,the

rack, in turn, reversely rotating the gear 6I and y just in front (to the right) of the toothed ends of their pawls 69 so that subsequent in adding operations, the pawls will trail over the grooves without engaging therewith.

The foregoing is a detailed description of a preferred embodiment of my invention, but it is to be understood that right is herein reserved to changes and modifications falling fairly within the scope of the claims appended hereto.
