Application filed November 27. 1907. Serial No. 404,0l9.
To all whom it may; concern:
Be it known that 1, Joan Asnrnr SMITH, a citizen of the t'nitcd States, residing at Harrisburg. in the county of Dauphin and State of Pennsyivania. have invented a new and useful Register for Addii'ig-Machines, of which the following is a specification.
This invention relates to computing devices. totalizers. or registers in general, but more particuiarly to a totalizcr adapted for use in a combined typewriting and adding machine such for instance as the Elliott- Ficher billing machine of commerce. Said machine is exemplified in Patents Nos. 820,879 and 829.971 to Laganke and Smith, and includes in its organization a typewriter of the downwardly acting or fiat platen type equipped with an adding mechanism, the latter embracing a totalizer mounted on the machine frame and actuating mechanism including a master wheel, rotated different distances by the respective nun'leral keys of the typewriter, and presented, by the movement of the typewriter carriage, into cooperative relation with successive denominational members of the totalizer. The arrangement of this class of machines is such, that upon the depression of a key, a digit will be printed in a given denominational position of the column being totalized, and the value of such digit is accumulated in the totalizcr or register by the simultaneous operation of the particular deucminational mei'nher which corresponds to the denominational position of the digit printed.
The object of the present invention is to produce a totalizer adapted for use in a machine of the character stated and arranged for the addition of whole numbers and fractions.
To this end the invention consists in mounting within the totalizer or register casing, a series of denominational members or registering wheels representing different denominations, as for instance units, tens, hundreds and thousands of yards, and an additional member or wheel representing fractional values, as for instance eighths, the several registering wheels being arranged for operation by a series of alined primary wheels of uniform dimensions periiherally toothed to engage the master Wheel as the latter advances from one priwheels is What is known mary wheel to another with the trptwtriter carriage.
Another object of the invention is to provide a space between the eighths and units of ards wheels to facilitate the readin; of the registered total, and to pr vide for the uniform spacing oi all of the idlers in order thafflii printing a number and a traction on the work sheet a space need not be left hetween. the fraction and the number, since such spacing is not customary.
Other objects subordinate to those ennmerated will app ar hereinafter as the de scription of, the illustrated embodiment of the invention is developed.
In the acompanying drawingsl igure l is a front elevation of the register. Fig. 2 is a similar View with a portion of the easing broken away. Fig. 3 is a plan view of the register with the top wall of the casing removed. Fig. 4 is a longitudinal section on the line &4 of Fig. 1. Fig. is a vertical transverse section on the line 5--5 of Fig. 4. Fig. 6 is a section on the line 6ii of Fig. ,5 looking in the direction indi ated by the arrows. Fig. 7 is a detail view of the eighths wheel, and Fig. 8 is a detail per spective view of an operating wheel and one of the gears whereby motion,is transmitted from said operating wheel to the eighths wheel.
Each part, wherever shown. is indicated by the some reference character.
'ithin the register casing 1 are mounted two shafts 2 and 3 located one above the other and journaled in the side walls of the casing. Norn'ially, however, these shafts are stationary and are onl rotated during the operation of resetting the register to zero, as will be described.
Rotatably mounted on the upper shaft 2 are five registering wheels (1, b, c, d, and e. The wheels I) to e inclusive are equidistantly spaced to accord with the letter space intervals of the tvpewriting machine, and in the present embodiment of the invention represent units, tens, hundreds and thousands of yards. Each of these yards as a ten-increment wheel and has ten peripheral teeth bearing upon their end faces the digits 0 to 9 inclusive, which are successively presented before the sight opening 4 in the casing l as the wheel rotates. The wheel a, which represents ighths, is spaced to the right of the units of yards wheel I) by an interval corresponding to one letter space of the machine and has a smooth periphery upon which is displayed a series of digits ranging from 0 to 7 inclusive. This eighths wheel a is what is known as aneight-increment wheel, since it has eight increments or units of movement for each complete rotation, to
successively display the eight digits upon its 1; .peripheries.
periphery opposite the sight opening 4, as distinguished from the other registerlng wheels, which, during each complete rotation, display successively ten digits on their The eighths wheel a is fixed to or formed integral with a gear wheel 5 so that the two wheels rotate in unison on the shaft 2.
On the lower shaft 3 are mounted five primary or operating wheels (1, b, c, d and e,
26 in alinement.
ing wheels, may freely pass from one wheel to another as the typewriter carriage advances from one printing point to the next. 7 The operating wheels I) to e inclusive are directly geared to the yard wheels I) to e inelusive, and upon the operation of any of said operating wheels, movement in like degree 1s transmitted to the corresponding ard wheels. This is not true of the operatmg wheel a and the eighths wheel a operated by it. .On the contrary, the fact that the unit of movement of the master wheel is always the same and that it corresponds to the unit of movement of each of the yards wheels renders it necessary to interpose a train of gearing between the wheels (1 and greater extent to the eighths wheel a.
a, as each increment of movement of the wheel a when operated b a; correspondin increment of movement 0 the master whee must transmit an increment of movement of In otherw rds, when the operating wheel a is given one-tenth of a complete rotation, it must impart one-eighth of a com lete rotation' to the wheel a. It is for t is reason that the wheel a is provided with a. gear 5,
as already stated, and the wheel -a is similarly provided with a gear 6 u on the some what 'elon ated hub 7 of whicli is mounte ,see Fig. 5. The two gears 5 and are .1 are disposed immediately adjacent to the {right hand wall of the casing 1 and are geared together b two idle are 7' and 8 meshing with eac otheran also with the gears 5 and 6 respectively. The ears 5 G5 and 6 are of difl'erent dimensions, t e ratio the wheel a being eight to ten. in the present construe tion, see Fig. 6, the gear 5 has twelve teeth and the gear (3 has fifteen teeth, the intermediate motion transmitting idle gears T and 8 having a similar numher'of teeth, the purpose of eln 'iloying a plurality of gears being merely to cause the number wheel to rotate in a direction opposite to the direction of rotation of its operating wheel.
The carrying mechanism, wl'lereby values are automatically transferred from each number wheel to the wheel of next higher denomination when the limit of value of the first named wheel is reached, is not novel. except as it may enter into novel combination with other elements or mechanisms.
Mounted on a transverse shaft 9 is a series of carrying levers 10 each having a long forwardly extending arm 11 and a short depending arm 12. To the arm 12 is secured one end of a spring 13 having its opposite 'end secured to the rear wall of the casing 1, as shown in Fig. 4. The several springs 13 constitute carrying or transfer motors, since they operate the carrying levers 10. The long arm 11 of each lever 10 has its front end bifurcated to form a locking arm 14 and a guide plate 15, the latter being guided in a kerfed bar 16 extending transverselyof the casing.
Pivotedlto each locking arm 14 is a transfer dog 17 the lower end of which is designed to engage over a tooth of one of the operating wheels (1 11, etc., so that when the transfer lever 10 carrying the dog is op- .100
erated by a spring 13, the dog will advance the operating wheel one increment and thus cause the corresponding number wheel to be likewise advanced an increment for the purpose of transfering a value thereto. Each of the transfer levers I0 is normally held in an elevated position by a selector 18 or 18. The selectors 18 are those which control the transfer levers arranged to 0perate the wheels-b toe inclusive. These selectors are mounted to swin from a transverse shaft 19 and each is yie dingly held in its forwardor effective position by a spring 20. Eachselector has a downwardly extended arm 21 having its lower end '22 bent laterally to cause it to engage under the lower edge of a transfer lever 10 immediately in rear of a shoulder 23, see Fig. 4. When, however, the lower end of the selector is thrown back to the position indicated in Fig. 4, its retaining end 22 will come opposite a slot 24 extended upwardly from the lower ed e of the lever 10, and as said slot is of S11 cient dimensions to receive the retainin portion of the selector, the lever will drop own, as seen in Fig. 4, to first advance. the adjacent operating wheel and then look the same by the engagement of the locking arm 14 between two teeth of the wheel, as shown;
ment on the wheel I), and, this being the In addition to the downwardly extending arm 21, each selector 18 has a forwardly extending arm :25 )rovided at its extremity with a contact plate 26 which extends between two adjacent operatingwheels, towit, the wheel served or advanced by the transfer lever controlled by the selector, and the wheel of next lower order.. This location of the contact plate on the selector brings it in position to be engaged by a transfer lug 27 projecting from the left hand face of the operating wheel at the right of the selector. Thus when any one of the wheels I) to a inclusive has been operated nine increments to cause the registration of 9 on the munber wheel of that particular order, the next increment of movement of said. wheel, as for instance the wheel 6, will accumulate the tenth increment of movelimit of value of said wheel, will cause the transfer lug 27 on wheel I) to on age the contact plate 26 on the adjacent se ector 18, thus urging the selector back to the position shown in Fig. 4 and allowing the transfer lever 10 to drop for the purpose of advancing the wheel of next higher order, to-wit, the wheel 0, one increment. This transfer movement of the Wheel 0 by its transfer lever, will cause the number wheel 0 to be advanced one increment, thus accumulating thereon the value transferred thereto from the wheel I) of nextlower order.
For a more complete disclosure of this carrying mechanism just described, reference may be made to the co-pendin application of Chas. F. Laganke and 01m A. Smith, Serial No. 308,209.
The selector l8 which controls the transfer of values from the eighths wheel a to the units wheel I), is somewhat different from the selectors 18 just described. It is identical with said selectors in so far as its retention of a transfer lever 10 for the wheel I) is concerned, but unlike the other selectors, it is not arranged to be operated by one of the primary or operating wheels. On the contrary, the selector 18 is provided with a laterally deflected arm 18".' The front ex tremity of this arm is provided with a cam '18 located adjacent to the left hand side face of the i hths wheel a and in position 'to be engage by a transfer lug 18" carried by said wheel, see Fig. 6. The selector 18, therefore, is .operated directly by one of the number wheels, to-wit, the wheel a, and serves to control a transfer lever which, when operated, engages and carries one of the operating wheels, to-wit, the wheel b. This difference between the selector 18 and the others of the series is necessitated by reason of the lack of uniformity in the movements of therwheels a and a. It is necessary-that the wheel a effect the carrying operation once for each complete rotation thereof, but as a complete rotation of this wheel does not represent a complete rotation of its operating wheel a, the operating wheel cannot be utilized for the operation of the selector, as is possible with the other operatingsvheels b to d inclusive by reason of the factr that said last named operating wheels and the nun'iber wheels geared thereto have uniform movements.
The resetting of the number wheels to zero is accomplished by mechanism which includes a. series of resetting cams 28 fixed to the shaft 3 to the left of each of the operating wheels b to e inclusive, and each having a shoulder 29, the several shoulders being normally alined. On the left hand face of each of the wheels mentioned is a resetting dog 30 urged toward the periphery of the cam by a spring 31. As the shaft 3 and the cams 28 are normally stationary, the rotation of the wheels I) to 6 will cause the dogs 30 carried thereby to traverse the periphcries of the cams and obviously, when a given computation has been completed, these dogs will be variously located with reference to the shoulders 29, according to the number which happens to be registered at the sight opening. If, however, the shaft 3 is given a complete rotation, the cams 28 will be carried with it and the dogs 30 will be picked up by the shoulders 29 and carried around to restore the wheels to zero. This rotationof the shaft 3 to effect the resetting of the yards wheels geared to the operating wheels I) to e inclusive, is accomplished by means of a resetting lever 31 fulcrumed at the left hand side of the casing, as indicated at 32, and having at its front end a toothed segment or "rack 33 which meshes with a resetting pinion 34 fixed to the left hand end of the shaft 3: When the rear end of the lever 31 is swung up the rack '33 will rotate the pinion 34, thus causing the latter to rotate the shaft 3 to reset the wheels in the manner stated. When the lever is thrown back to its normal position, the shaft 3 and the cams thereon, will be reversely rotated, but the wheels wil remain stationary, th retention of the wheels being effected by the locking ends 14 of the resetting levers, which wlll have been depressed during the resetting operation, and by spring urged locators 35 which engage each of the operating wheels a. toe.
It will be noted that thus far no mention has been made of the resetting of the eighths wheel a. This wheel cannot be reset through the medium of its operating wheel a as are the several other number wheels,
its operating. wheel, said wheel a is pro videdon its left hand face with a reset ting dog arranged to be engagedby a smuldered resetting cam 28 fixed to the shaft 2. The shaft 2, like the shaft 3, is normally stationary, but when the shaft 3 is rotated to reset the wheels 6 to e inclusive, :1 gear 36, keyed to the shaft 3 adjacent to the left hand end thereof, serves to drive a gear 37 keyed to the shaft 2. so thatboth shafts will rotate. This rotation of the shaft 2 will cause the cam 28" thereon to enact with the resetting dcg 230 and thus reset the eighths wheel a to zero simultaneously with the resetting of the other wheels.
As is well understood in the art, it isjnecessary after each number has been added to the amount previously accumulated in the register, to retract the transfer levers and selectors which may have been operated. This is accomplished by a rocker, 38 located below the transfer levers and geared to a slide 39 operated by the typewriter carriage to swing the rocker and thus elevate the levers 10. It is also necessary to retract the levers l0 and selectors 18 and 18 before the resetting operation and after such operation.- because when it is desired to reset, some of the levers may be down, and of course all of them move down during the resetting operation because all of the wheels necessarily move from 9 to 0, thus causing the transfer lugs to throw the selectors back. This resetting of the levers 10 and selectors 18 and 18 before and after the resetting operation, is effected by the manipulation of the resetting lever 31 which is provided with a cam 40 arranged to operate a slide operating lever 41 connected at its lower extremity to the slide' 39. When the resetting lever is operated, the cam 40 will cause the lever 41 to retract the slide 39 to swing the rocker 38 and thus cause the lovers 10 to be moved away from the wheels a, 6, etc, before the dogs on said wlieels have been engaged by the resetting cams. The wheels will then be reset by the continued movement of the lever 31 in a manner already described, and incidental to the resetting, the selectors 1.8 and 18 will move back and the levers will drop down. Upon the retraction of the resetting lever 31, however, the cam 40 will again operate the rocker 38, through the medium of .the lever 41 and the slide 39, to again reset the transfer levers and selectors to normal position. Thus when the lever 31 has been operated and restored to position, the number wheels, transfer levers, and set lectors, will all be reset to position for the performance of another computati n. Theengagement of the transfer dogs 17 with the operating wheels a, 6 etc, is insured by a vibrator 42, operate in a manner well understood in the art by the typewriter carriage to urge the dogs 17 forward and thus insure their engagement with the teeth of the operating wheels at the proper time.
Attention is now directed to several distinguishing characteristics of the described register. It will be noted that all of the wheels are of the same diameter and that each series of wheels, to-wit, the number wheels and their operating wheels are alined. Yet, notwithstanding this uniformity of dimensions and alinement, one of the registering wheels, to-wit, the wheel It has a unit of movement of greater extent than the unit of movement of any other wheel. l urthern'iore, while the operating. wheels are equidistantly spaced, since equidistant spacing of nun'ibers and fractions is usual in the printing thereof, the fractional. number wheel, to-wi t, the eighths wheel a, is spaced from the yards wheels by a considerable interval to facilitate the reading of the number registered at the sight opening. Attention is also directed to the fact that' the parts are arranged in the casing in a manner which is distinctly economical of space, the train of gearing between the wheels a and a. being located at one extreme side of the casing and the train of gearing between the two shafts being located at the other side of the casing and spaced therefrom by only such interval as is necessary for the accommodation of the resetting lever and gear. v a
It is thought that from the fore oing, the construction and operation of this register, designed for addition in yards and eighths, will be fully understood, but I expressly reserve the right to effect such changes, modifications and variations of the illustrated structure as may come fairly within the scope of the protection prayed.
