To all (whom it may concern:

Be it known that I, IIYMA-N Enr-GOLD- BERG', a citizen of the United States, residing at Chicago, in the county of Cook and State ol7 Illinois, have invented a certain lnew and useful Improvement in Calculating-Machines, of which the following is a specifica- My invention relates to calculating machines including calculating attachments to typewriters, and the object of the invention is to provide means whereby the operator may predetermine whether the machine's to add, subtract, or not operate, the actual operation ol this,controlling device to be-autoin atic orinherent in the machine itself. This invention is not here claimed to be broadly new, as it is shown in a rior patent application for calculatinfr mac ines filed by me in the United States lI-atent Office, August 25, 1005, Serial Number 275,780.

Broadly speaking, the 4invention is also shown in the United States patent applications filed by me December 25, 1905, Serial Number 292,932, and .April 21, 1906, Serial The distinguishing feature of the present invention vrelates more particularly to the mechanism by which motion is transmitted from the-dillerential mechanism to the totaliz'er, and to the mechanism by which said transmission mechanism is operated. In the actual design of the machine here shown, this transmission mechanism consists of gear wheels and means V.for automatically controlling whether the number of gearwheels in the mechanism shall be an odilior an even number, thereby determiningr in what direction the totalizer shall operate.

The object of the present invention there- 'fore may be more specifically said to be to provide a particular type of transmission mechanism and controlling means therefor. I accomplish my object by the mechanism illuslirated in the accompanying drawings, in whic 'i Figu re 1 is a front -view of a typewriter embodying my invention. Fig. 2 1s a fragmentary plan view showing the totalizer, totalizer support, transmission gearing, and'controllin device. Fig. 3 is a fragmentary. front e evation of most of the parts shown in Fig. 2. f Eig. 4 is a transverse sectional elevation tekenen 4---4, the totalizer is shown to be out of operative Specification of Letten; Patent.

Figs. 5 and 6 are sm'iilar to Fig. 4, excipt that in one view an odd number ol'A gear wheels is actively interposed between the ditl'crential mechanism and the totalizer, and in the other view an even number ol' gear, wheels is interposed between the d ille'rential mechan-v ism and the totalizer. lonseiquently, in Fig; 5 the action ol" the differential'mcclianism will cause, for example, addition, -while in Fig. 6 the action of thedillercntial mechanism in the same direction will cause subtraction.- Figs. 7,' 8 and Y9, :are vertical sectional views of the controlling pins showing the different effects. which may be had upon the controllingportion thereof b y turn.- -ing them to different positions. Fig. 10 is a bottom view of the totalizer showing the controlling eam thereon. Figs. 1'1 to I8 inclusive illustrate the interior construction of the totalizer. Fig. 11 is a ront assembly view partly in section, showing the relation of the different totali'zer arts. Fig-12 is similar to Fig. 11, except t at it shows theI different pieces spaced somewhat apart to better illustrateI their construction. Fig. 13 is a-sectional view ofthe intermediate wheel located farthest to the right in the .totali'zen Fig. 14 is a sectional view taken on Ihrem-44, Fig. 11. Figs. 15-to 18 inclusive areside views of component. parts of the totalizer.

Similar numerals refer to similar parts throughout the several views.

rl`his invention might have been embodied in an inde endent calculating machine,` either ree-ori ing or non-recording. But I have chosen to embodyit in a calculating typewriter attachment-and' the 'form of typewriter selected is that of the well-known Remington s't 'le in which there is a stationary framewor travel thereon, Aand operating keys 3. 'i This present invention i's not particularly concerned with the form ol' differential mechthat the difereittial mechanism desi nated by the numeral is operated by the eys 3 to`-drive the 'shart 5 diierent amounts depending upn the' value of the keys struck.

form of differential or digitizing, or valuating4 mechanism, as it u variously termed in the art, is sli-own and descfii'red. in ti-re Paten-t Number 782,554, issued t Vme February 1.4,

1, a carriage 2 adapted to anism employ-od, and it is su'llicienttc say 4-And for use in this connection, asnitable 1905. The totalizer which for the present will be designated in general by the numeral (i is adapted to travel in unison with the typewriter carriage and has aset of wheels yfor receiving motion from the actuating l beve gear wheels 9 and 10, or any other suitable connecting devices. Saidpimons 8 are concentric with shaft 7 and extend across the :machine within the o Verative limits thereof, as best illustrated inl 1. In the present design said universal pinions are non-traveling, and their 4aires are fixed, the shaft 7 being journald in thestationary bracket or platform 11 fastened to the typewriter frame work 1.

A master-shaft 12 having one or more master Wheels 13 thereon is journaled in a stationary part of the machine, for example, upon the brackets 14: secured to the platform 11. Said shaft is therefore non-traveling and is rotatable about a fixed axis. Said master wheels are desi ned to mesh'with the totalizer wheels' 31 o the totalizer in the manner again `tobe referred to and the .mechanism for transmitting motion from Lbility of amplification of the invention and the universal pinions to the master wheel, which forms one of the features of-this invention, will now be described.

For the purpose of illustrating the possiits adaptability to commercial requirements,

plurality of master wheels.

totalizer, an

I have shown a plurality of totalizers and a At each master wheel 13 there is mounted upon platform 11 a slide 14 ada ted to move transversely to the direction o travel of the typewriter carriage and totalizer. Any suitable form of guiding meansfor directing and controlling the sliding movement of said slide u on its latform-may be employed, the mec anism 1ere shown being screws 15 screwed or otherwise rigidly secured to the slide 14, and working in slo't 16 in platform 11. Mounted in each slide are two transmission gears, one of said gears consisting of a single spur wheel 17, and the other gear consistmgiof two intermeshing s ur wheels 18'and 19.

The actua number of wheels in each gearingr is non-essential, the 4material fact being that in 'one of said [gears there is an odd number et wheels' ane rrr this other an even number, so that whenone gear is in ope-ration it will Cproduce one`effect upon the when the other gear is 1n wheel1'3; and when said slide is in the. opposite shifted position (shown, for examp e, in Fig. 6) the wheel 18 will be in mesh with the pinion 8, and the wheel 19 will be in mesh with the master wheel 13. When wheel 17 is in active position, shown in Fig. 5, wheels 18 and 19 are 'disengaved from wheels 8 and 13, and, converselI when both with the pinion 8 and withl the. master wheels 18 and 19 are in en avement with wheels 8 and 13, wheel 17 wi l be out of engagement therewith. In other words, only one kind of gearing is 'in operation at a time. This would rovide for either addition or subtraction, ut in order to render it possible for the totalizer to be non-active at a time when its receiving wheels are oppositeto a master wheel, it 1s desirable to arrange for an intermediate position of the slide 14, as shown in Fi 4, so that when desired, neither the w ieels 17 or the wheels 1S and 19 shall be in operative connection between wheels 8 and 13. Such an arrangement is here provided and asa result it i s possible to obtain three different conditions, to-wit, action to add, action to' subtract, and nonaction.

Reference will new be made to the means whereby slide 14`is shifted backward or forward transversely to the path of the totalizer travel. In said slide there 'are one or more depen ng upon the number Vof' totalizers to be employed in the machine. AIt is desirable that each totalizer shall have its own pocket in order that .its operation may be independent of all the other totalizers. Each pocket is adapted to receive a controlling iece, the pre erred construction whereof is est illustrated in Figs. 7, 8 and 9. As shown there, said controlling pieces consist of a base 21 adapted to fit in said pockets,

.and upon said base there is a pin 22 adapted to be received within the cam groove 23 u on the bottom of the totalizer, as best siown in Fi 2, 3, 4 and 10. By preference, said pins 22 are eccentricall located upon their bases 21, and said square in horizontal cross-section, so that they may'fit into pockets in an one-of three different positions so as to ring the pins 2.2 at the back, 1niddle, or front of the pockets, as illustrated, respectively, in Figs. 7, 8 and 9. In order that the cam 23 upon I 1 1.. l. the total-12; may, notan-1 upon tue pins 22, control the s ted position of slide .14, it is necessary, of course, that said cam" should have a fixed path of travel and one (pockets 20, the number `of pockets lon .as the ath of the cam remains fixed an( it trave s in unison with the totalizer. The referred construction for causing the totahzer to travel in a fixed path and in unison with'the typewriter carriage is best illustrated in'Figs. 1 and 4, wherein it is shown that said totahzer is rigidly mounted upon a bar 24 rigidly fastened to the brackets 25, which, in turn, are rigidly secured to -ed in the totalizer casing 30.

.or foundation from which the slide 26. Said slide is slidingly mounted upon the guide b'ar 27. parallel with the direction of travel of the typewriter carriage, and is caused to move in unison with the carriage by means of its engagement with an arm 28 depending from the typewriter carriage, as shown in Fig. 1.

Although the totahzer per se is not here claimed to be new, it being shown and de scribed in my United States Patent No. 782,605, granted February 14, 1905, for a totalizing mechanism, I will briefly describe the construction of said totahzer. It will be understood, however, that other forms of totalizer might be emplo ed, for example, the one shown in Patent o. 741,961, granted to me October 20, 1903. The important thing to be considered in the totallzer is that the wheels actedupon by the master wheels 13 shall'be'capable of rotating in both directions, one for addition and the other for subtraction.

Referring to the totalizer details shown in Figs. 11 to 13 inclusive, 29 represents the totahzer shaft which is non rotatably mount- U on this shaft'are supported a plurality of) sets or groups consisting of five principal iarts, to wit: the receiving or totahzing wheels'31,the carrying pinions 32, the receiving or accumulating w ieels 33, the epicyclic pinions' 34 and the intermediate wheels 35. V heels 3l, 33 and 35 are all freely rotatable about shaft 29 with the exception of wheel 35 located at the extreme right to correspond with the units column. This wheel i`s rigid on the shaft and its function is to form a fixed basis the rotatable parts of the totahzer move their definite amounts.

' In each group of parts 36 represents a dish like supporting piece which is splin'ed to the shaft and has atits left )ox-tion a cylindrical hub 36which forms a hearing whereon the intermediate wheel is freely rotatable. The pin 37 extends toward `the left from 'piece 36 and serves as an axle whereon the carrying pnon' freey rotatabe. Said Bar 27 is arranged' carr 'in Y pinion has four long and four short teeth w lich alternate with each other as best shown in Fig. 12. By means of its teeth said carryin pinion is alternately loc 'KCJ and rotated by tie locking rin 31 and carrying teeth 31b respectively of t e totalizing wheel 31 at its ri ht. The short teeth serve to make the le t ortion of the carrying pinion a complete eig it toothed gear, and this lett portion of the carrying pinion remains per manently in gear4 action with- .the internal gear portion 3l c of the next totalizing wheel to the left, by means of the gear 33, 34 and 35 hereinafter described. As a result of the carrying action of pinion 32 is always transmitted to the next higherv totalizing wheel 3l. Each totalizing wheel 31 has a set of numerical figures on its exterior cylindrical surface and is supported by the contact ol" its internal cylindrical surface 31-(which constitutes the aforesaid locking ring) upon the cylindrical ed e of the supporting disk 36, said wheels 31 caring loosely upon their supporting disks so as to be freely rotatable.

independently thereof.

The accumulating wheels 33 are plain spur gears having a comparatively large eentralaperture 4so that they may set over and be free] rotatable upon the points ofthe teeth o the intermediate wheels 35. Said accumulating wheels are narrow and their teeth roject beyond the circumference' of totalizmg wheels 31, so that they may be engaged by the master wheels 13. The totalizing wheel 3 ldand supporting piece 36 (shown at the extreme left ofFg. 11) are slightly modified to im art a finished ap earance to the extreme le t end .of the tota izer.

' Extendin leftward from each accumulating whee 33 are two pins 33 which constitute axles whereon the epieyclic pinions 34 are freely rotatable. Said e icyclic pinions remain in mesh with bot 'the intermediate wheel 35 and theinternal gear portion 31c of wheel 31 for transmitting rotation from one to the other. The aforesaid intermediate wheels 35 are wide faced spur pinions designed to both support. the accumulating wheels 33 and also remain in mesh with the carrying pinions 31 and epicyclic pinions 34 at the left and serve to transmit the'carrying' action of the carrying wheel to the epicyclic pinion and thence to the next higher totalizlng wheel 31. As a result of the above described construction of the totalizer it follows that the accumulating wheels 33 are rotatable in either direction and when rotated in one direction will add and when rotated in the opposite direction will subtract.

l'n o eration, a pin 22 is so set in its pocket 20 in s ide 14 that when the totahzer comes along said slide will be shifted to the front or to the rea-r or to an intermediate position,

vdepending upon whetherthe `eip'erator de;

sires the totalizer to add, Subtract or not operate at that oint. If the'pin is so set that the approac ing cam 23 will throw the slide 14 toward the front, the sin le wheel 17 will be thrown into mesh withw eels 8 and.

13 for transmitting motion in one direction, but if said pin is so set that the slidew-ill be shifted'toward the rear then-the two wheels 18 and 19 will be thrown into mesh with wheels 8 and 13 Aand motion in the opposite direction will be transmitted, so that m one position of the slide the totalizer willbe 'made to add, while in the otherv position of said slide it will be made to subtract, and in an intermediate position no action of the totalizer will occur.
