.Patented Nov. 19, 1907.

Original application filed J auuary 17. 1901'Serial No. 43.599. Divided and this application filed April 27, 1901. Serial No, 57,797.

To all whom it may concern:

Be it known that I, JASON C. LOTTERHAND, a citizen of thel United States, residing at the city of New York, in the county of New York &.and'State 'of New York, have invented certain new and useful Im rov'ements in Adding Attachmentsior Type- Vriters, oil-which the f ollowinor is a description, reference being hhad to the4 accompanying drawings, forming 10 part of this speciiication.

The present ap lication is a division of application Serial No. 43,599 filed by me on January 17, 1901, for improvements in typewriting machines and adding attachments therefor. The subject matter of the present application consists of certain improvements in adding machines and in their combination With typewiiting machines all of which will be hereinafter more fully described and particularl y pointed out in the claims.

In the accompanying drawings Figure 1 is a top plan view of the machine, with the upper part ofthe casing removed and part of the frame work broken away, to expose the parts beneath; Fig. 2 a middle vertical section of the machine; Fig. 3 a sectional'plan view of the forward part ofthe machine beneath the type-keys; Fig. 4 a top plan view of the paper-carriage of the typewriter, with the adding device mounted thereon; Fig. 5 an elevation of the left hand end of Fig. 4

Fig. 6 an enlarged. detail view showing one of the adding keys and`co erating parts; Fig. 7 a detail of some of t e same parts; Fig.' 7a a detail from Fi 7 showing the graduations of the cams; `ig. 8 a view correspondino` to Fig. 6 with the adding key artially depressed and coupled to the t pe ey; Fig. 9 a similar view showing the ad ing key fully depressed; and Figs. 1() to 14, inclusive, detail views of the addin device.

The same reference numerals re er to identical parts in the several wiews. A

The description of my present invention may be best understood if prefaced b a briefv explanation of the t -bar and 'ey mechanism of' the t'd ewritin machine in connection with wluc my a'. ding attachment is illustratedP in the accompanying drawings. This mechanism is best shown in Figs. 1, 2, 6, 8 and 9 where it Will'be seen that the operatingtype keys of the machine consist of thin arms or plates 1 rigidly sebb cured at their rear ends to vertically shdihg rods 2 (or formed integral therewith), and having secured to their-front ends vertical stems 3 passing upward through and loosely guided in'apertures in the forward top plate 3a ofthe machine and carrying at their upper ends the usual key-buttons 4. The rods 2 are arranged in a semi-circle in front of and concentric to the printing point, as shown in Fig. 1, and are guided at their upper and lower ends in the frame plates 5 and 6, or bearings upon said plates. Each of these plates is of coinci ent apertures for the passage of the iupper and lower ends of the rods 2, but in the present instance, to relieve friction, the rods 2 do not have-their bearings directly in said apertures but are guided by and have their bearings between pairs of grooved an tifriction rollers 7 which are mounted as shown in ,supports 8 upon the frame plates 5 and y6. Coiled springs 9 connected at their lower ends to the key plates 1 and at their upper ends to the under side of the trame plato 5 yieldingly hold the rods 2 in elevated posi-l tion and serve to return them thereto after depressions of the keys.

' Secured upon the rods 2 are collars 10, provided upon their rear or inner sides with ears 11 proJecting radially toward the printving point, to which ears are connected the upper and outer ends Aof wires or rods "12 Whose lower or inner ends are connected to the type-bars 13. These type-bars are pivotally su ported at their lower ends, concentric to t e printing point, in hangers 1S upon the trame plate 6, and carry at their upper ends the usual type-blocks 14 bearing upperand lower case type-characters. The depression of the rods 2 causes the type-bars to be swung inward and downward and their type brought into contact with the upper side of the platen roller 63 at the rinting point, while the return of the parts y the springs 9 restores the type-bars to their normal position, where they rest against a suitable semi-circular support 15 secured to and depending from the frame plate 5.

The purpose of my novel adding attachment, constituting the subject, matter of my present a plication, is to enable amounts to be printe upon thesheet of paper upon the platen roller on the paper carriage of the typewriter and at the same time add it into a. total sum upon the adding device, so that rovided with a semi-circular row when the foot of the column of workl is reached, the total of the amountsin the column ascertained' by referenceA to the adding device and the necessity'lfor .adding up the column by mental calculation be thereby obviated. I am of course aware that it has heretofore been proposed to cornbme vadding mechanisms with typewriters in various ways for this purpose, and my invention consists in a novel and improved combination of adding mechanism and type- 'writer, as well asin novel features of the adding mechanism itself. What I will term for brevity, the adder A of thismechanism is mounted upon and adjustable longitudinally of the paper carriagev of the typewriter, Figs. 1, 2 and 4, to which end the base plate 31of the paper-carriage has secured to its right hand end, Fig.' 4, a forwardly projecting side vplate. 205 inlwhich are journaled the right .hand ends of three rods 206, 207 and 208, whose opposite ends are jo'urnaled in a corresponding side plate 209 secured to and projecting forwardly from the Vbase plate 3 1 of the paper-carriage at.`its left hand end. The rods 206, 207 and 208 are provided 'at .theiropposite ends, with milled tain such engagement.

thumb Vpieces by which they may be readily turnedfor purposes hereinafter described.

The inclosing casing of the adder A is pro` vided upon its rear side with ears 210, Fig.

A4, through which passes the rod 206, while at its upper forward corners said casing is ,provided with eyes through which passes the rod 208. The rod 207 passes substantially through the center of the adder and is provided with a longitudinal groove; While the rod 206 is screw-threaded, and the rod 208 has its under side cutaway Figs. 10

and 14, all for purposes hereinafter eX- plained.-

i F ulcrumed upon the left hand side of the casing of the adder is a lever 211, Figs. 4 and 14,' whose rear end is bent to correspond to` the pitch of the threads upon thescrew rod 206, and fits in a corresponding slot in the left hand lear 210 ofthe adder casing, and when permitted engages the threads of the 'rod 206 as shown inFig. 14, a coiled spring 2,12 connected to'the lever tending to main- The upper forwardend of the lever 211 fits against the flattened or cut away under side of the rod 208, 'Figf 14, ,and when saidrod is turnedl so as to bring its upper rounded surface against the 'lever the latter will be rocked and its Alowerrear end thrown upwardl out of engagement with the threads upon the screw rod 206.

As willbe understood from the foregoing description, by turning the'rod 208 so as tol disengage the lever 211 from the screw rod 206, the adder will be disengaged from'said Irod and left free to'slide longitudinallyuponthe rods in either "direction, while when the lever is engaged with 'the screw rod20'-tho adder lmay be adjustedflongitudinally of the rods by turningthe rod 206.' The purpose of these provisions vislto'enable the adder to be slid along the rods by hand, to quickly adjust it to approximately the desired position, and to then enable its niceradjustment to the exact -position desired toibe effected b f turning the `screw ,rod 206. vIn effecting these adjustments,.-tqsi'mply necessary to irst turn the rod 20K-seras to disengage the lever 211 from the vscrew rod 206, then slde the adder along the Yrods: to approi'rimately the desired position, andfthen turn the rod 208 back to normal l:position and effect the" final setting of thea der by turning the-rod 206. The adder casing is provided upon its opposite sides with milled vthumb pieces or handles,A 208, for shifting it laterally by ABefore entering upon-:a: description of the paratory to an explanation of the means for actuating it, it Will suflice to say that the adder contains a series of registering wheels 4213, Figs. 14, 11 and 13 which represent units and tens of cents, and units, tens, hundreds,

thousands, tens of thousands, hundreds of thousands, and millions of dollars, respec- -mechanical details` of the adder, and pretively, and are actuated by corresponding` pinions 214 projecting from the front side of the adder, which pinions are in turn actuated by a gearvtoothed segment or sector 215 carried upon the rear end of a lever 216, Figs. 2, 6, 8 and 9. This lever 216 projects rearwardly from, 4and its forward half or end p c'nstitutes a rigid part of, a rocking frame yB fulcrumed upon a rod 217pand composed of a series of thin bars or levers 2 18, Figs. 2, 3,. 6, 8 andQ, rigidlyconnected together'at their forward ends by a tie-rod 219, and slightly in rear of the rod. 217 by a second tie-rod 220. As appears in Figs. 6, 8 and 9,

theforward end of the lever 216 constitutes one of the arms 21-8 of this rocking frame, and in the further description of the parts it vFvillbe considered simply as one of said arms,

The rod 217 upon whichv the rocking frame is fulcrumed is sup orted at its opposite ends in the upper en s of a bell-crank frame C vcomposed of a'pair 'of bell-crank arms or levers 221 vrigidly connected together by tie- -rods 222 223,' to form a single rocking frame,

and fulcrumed Vat their `angles upon a rod 224'1secured at its opposite 'ends in the side frames of the machine. The rear ends of the bell-cranks 221 are connected by a trans-' verse vrod 225 which cooperates withA the cams hereinafter described. 'A stud 226 Fig. 9 projectinginward from the left hand side frame of the machine Figs. 6, 7, 8 and 9 asses through a` slot 227 in the vleft hand 'y y:

. ll-c'rank 221 and limits the'forward and backward movements yof the upper ends of s id'pbell-cranks andthe rocking frame of snaai which. they constitute a part. connected at their upper rearends to thefront ends ,of several ofthe arms 218 of the rockingl frame B which carries the lever 216 and sector 215, and at their lower forward ends to lugs upon the inner side of the front frame plate, Figs. 2, 3 and 6, and a supplemental spring 228a connected to the upper end of t 1e righthand bell-crank 221, Fig. 3, serve to pull the frainesiorward to the limit of movement permitted by the stud 226 engaging the slot vin the bell-crankl 221, and to also v ieldingly hold the rear end of the lever 216 and sector 215 in elevated position, as shown in Figs. 2 and 6, in which position the upper edge of the lever 216, or alprojecting bearing surface thereon, rests against the un.- der side of' the frame plate 6. The springs 228 thus serve to yieldingly hold the sector 215 in and return it to its normal upper ,and forward position, in which position it is out of mesh with the pinions 214 of the adder A, as shown in Figs. 2 and 6. When, however, the lover 216 is moved rearward the sector 215 will be engaged with one of the pinions 214 of the adder, as in Fig. 8, and'when the sector is then swung downward such -pinion will be turned a distance corresponding to the downward movement given the sector, and a corresponding amount be added upon the registeringI wheel 213 actuated by such pinion. Such rearward and downward movements are given the sector 215 at each 'adding operation of the machine, by the means to be now described.

It will be seen that the adder wheels of the adder are arranged in divisions. the cents division is separated a vspace from the hundreds division, andA the latter a higher space' from the thousands division, and. as the platen and carriage must move to a greater extent in carrying the adder wheels pastfthe sector between such divisions, the iigures of the numbers printed have s aces between the different divisions, thus acilitating the return of the number and dis-v tin guishing between dollars and cents.

As shown in Fig. 1 the keyboard of the machine is provided, in rear of the regular typekveys, with. a supplemental row of keys w ose linger buttons 229 bear in successionthe nine digits, in regular order from left to right, and also acipher and period upon the tenth'and eleventh keys at the right hand end of thel row. The iirst nine of these sup lemental keys censtitute the adding ke s o the machine, whle the two additiona keys are provided for convenient use in conjunction with such adding keys, as hereinafter explained. The finger buttons of these supplemental adding keys are mounted upon the upper .endsof straight vertically reciprocating stems or Shanks 230 which are ded near their u v ends in slots in the orward to plate o the machine, and at their lower en Springs 228.

That is,

`of .each of the plates 235 is a cam in slots in a transverse plate 231 secured at its ends to the opposite side frames of the machine, Figs. 2, 3; 6, Sand 9, and in guide brackets 231'* secured to the under side of the plate 231,Figs. 6,8an,d 9. Eachkeystem 230 is combined with means for actuating the adding mechanism therefromfeach key impart# ing apositive and definite and uniform degree of movement differing in degree from that of each of the otherkeys. Thus each stem is provided upon its forward. edge, about mid.- way of its length, with rack teeth 232 engaging a pinion 233 mounted upon a stud 234 projecting from the side of a supporting plate 235 and having fastupon and turning with it a cam 236y having a hooked or slotted tail 236 and ada ted to coperate with -a stud 237 (surroun ed by an anti-friction collar) projecting from the side of the adjacent arm '218 of the rocking frame B which carries the lever 216 and actuating sector 215, as hereafter described. There is one of the supporting lates 235 for and beside each of the adding ey stems 230.- These plates are in the-present instance of the irregular shape partially indicated in Figs. .6, -8 and 9, but their upper ends are there hidden b the key stems 230, since the upper ends of t e lates and the key stems are. of substantialiy thev same width, as shown in Fig. 3, where the u per ends ofthe plates are shown in section.

ese narrow upper ends of the plates iit and are supported in slots in the to plate of the Mounted u on-a vscrew stud 239 upon the portion isk 240, Figs. 6, 8. and 9, provided in its periphery with three notches or recesses a b c ap roxilower end of t e forwardly projectin mately equi-distant from each other. n the normal position of the arts the lowermost notch a engages the ro 225 of the rocking bell-crank lra'me C, the forward notch b re-v ceives a stud 241- on the plate 235, which limits the turning movements of the disk upon the stud 239, while the third notch c cooperates with two spring-pressed dogs or pawls 242 -243 mounted by slots and screw- -studs upon the side ofthe key stein 230 ,and

pressed forward by vsprings 244 secured at one endto the ke stem 230 and at their opposite ends suita ly connected to the pawls 242 and 243. It results from this construction and arrangement of the parts that wheneverone of the addi keys is depressed its pawl 243 will en age Itie shoulder on the disk 240 formed by t e lower wall of the notch or recess c in sald disk and turn the latter 'from the position shown inlFig. 6 to that shown 1n Fig. 8, in which latter position thev disk will 'i beheld, with the lower wall of its notch b in contact with the stud 241, byv a coiled spring 245 connected at its lower. end to a pin upon the disk and at its upper end to the plate 2.?5.\ This movement ofthe cam disk 240 from 4the position of Fig. 6 to that'of Fig; 8 will have forced the rod 225 of the bell-crank frame C downward and throw the upper'end of said frame rearward, and thereby shiftedv the frame B rearward andengaged'the sector 215 withpne of the pinions-214 of the adder A, as shown in Fig. S, so that any downward movement then given the sector 215 will be trans-A y the keys, but that on the movementof any .due to momentum given the one ci2 the adding keys the actuating mechanism and the adding mechanism are operatively connected. lAs the downward move ment of the key stem 230 continues the cam 236 geared to it by the pinion 232 will receive in its slot the stud 237 and force the rear end of the rocking frame and the sec-tor2l5 downward a distance proportionate tothe'pitch of the cam. The pitchofthe yrespective cams is so graduated Fig. -7il that-the cam l eared to the left hand or units addi-ngkey wi 1,at .a full depression ofsaid key, move the sector 215 downward one unit offdistanee, and add a single unit to .the registeringwheel in gear with the segment at such time; while. the succeeding keys to the right will move the sector additional units ofdistance corresponding to their respective values'and transmit correspending'v degrees of movement to the reg' tering wheel in gear with the segment.

intogf engagement 1 with' the I isc between the two arms ofthe bell-crank limitsv the iuowlnents of the latter in opposite directions, while a coiled spring 251 connected at its upper end to the plate' 235 and at its lower end to the lower arm of the bell-crank yieldingly holds the latter in its opposite positions when moved thereto by the contact of the studs 248 and 249 with its upper arm as described.

As will be understood from the foregoing description, when any one of the adding keys is depressed the sector 215 is first thrown rearward and engaged with the adder pinion 214 which is at the time in line with it, and is then swung downward the full distance required to add in the adding mechanism an amount corresponding tc the value indicated .by such operated key, after which, at the'vv return upward movement of the key, the sector 215 is first withdrawn from engagement with the pinion, by the action of the springs 228, and then swung upward to normal po-` sition..

The importance of the absolute locking to gether of each adder key and the actuating mechanism, and of insuring absolutely the full and complete movement of the keyafter` such movement is begun will be evident. If an adder key could be `partly depressed and `then return to normal position, the result would be to move the adder wheels to an extent to'indicate in theadding mechanism an amount less than that indicated by the key, or printed by the connected type. Further, if the key and actuating mechanism were not locked together, a percussive blow on the key might partially depress it and yet cause the actuating mechanism to move by momentum to a greater degree than required to add the amount indicated by the key.

A supplemental set of type-bars and con nections cooperating with the adding keys might of course be provided for the purpose of'F enabling the amounts added upon the adding device to. be simultaneously printed upon the sheet of paper on the platen roller, as has heretofore been proposed in machines of this class; but a further feature of my invention consists in combining the adding keys of a machine of this character with the'printing devices operated by the corresponding type-keys of the machine in such manner that a single set of type-bars and connections suffices both for the adding vkeys and the corresponding type-keys in the regular keyboard of, the machine. This enables me 'to dispense with the ninetype bars andr their connections which Lwould otherwise bejrequired for the addingkeys, and correspondingly reduces the number of parts inthe maclune and enables all of the type-hars and theirvcon'nections in a combined typewriting and adding machine tobe arranged in the same manner and in the tances below the top same space as in an ordinary typewriter having no adding mechanism,

.[n myp'resent machine a simple and con venient method of vcombining the` adding keys with the printing devices of the corresponding typekeys has been to provide means lor automatically and positively locking to gether the adding keys and the iorrespondi ing type-keys whenever the adding keys are t depressed, and thereby cause such t to be carried downward by and with. the adding keys, to actuate the corresponding type-bars, and as the adder keys are compe led as before described tov make a full and complete movement, the adding in the adder mechanism of the amount represented',

bythe key depressed is absolutelyvinsured,

a result essential in the practically opera-L tive machine. It willbe evident thatif the adder key and the corresponding ty e kej,T were not locked together and the ad er key could make a partials'troke, such partial stroke might throw the type key sufficiently to print the figure, while anamount less than represented by said figure would be added 1n the adding mechanism. One means of carrying out this method is illustrated in Fi s. 6, 8 and 9 of the drawings, Where it' wil be seen that the stem of each adding key 230 has pivoted to it7 some'dislate of the machine, a bell-crank lever 252 liia'ving a hooked uppe'r end adapted to cooperate with a stud 253 vupon the side of the horizontal plate or arm 1 of the adjacent type-key to lock the two together. .A' spring 254 Figs. 6, 8 and 9 coiledaround the pivot of the bell-crank 252 and connected at one end to the key stem and at its opposite end to the forwardly projecting horizontal arm of the bell-crank tends to throw the verticalarm of the bellcrank rearward and engage its hooked upper end with the stud 253 upon the type-key )late l', and thereby positively lock the typekey and adding key together, but when the key stems 280 are in their u per and normal position the upper arms of) the bell-cranks are held rocked forward as in Fig. 6 by contact of the front ends' of their horizontal arms with stoppins 255 projecting rear-v wardly from collars fast upon a fixed rod e-keys 256 secured at its opposite ends in the side frames of the machine, Fig. 3. When the adding keys are in their upper and normal position, therefore, the hooked arms of the bell-cranks 252 are held out of the path of the studs 253 upon the type-ke s, and the latter are free to be depressed in ependently of the adding keys, in the ordinary operation of the typewriter; while when any adding key is depressed its first downward movement will carry. the front end of the lower arm of its bell-crank 252 away from the pin 255 and permit thespring 254 `to throw the l key can move independen.

hooked upper end of the vertical ofy said bell-crank rearward into engagementjiollows:

with the stud 253 upon the type-key, as iny Fig. 8, and thereby, look the two keys together, so4 that during 'thegiurther 4downen ward `and return upward rn-mernentv neither and the amount represented -theaddin' key will be added upon the; dlngldevice anc be also printed upon the paper on, the platen by the type-bar connected tothe type-key.'

simp e lug projectingnfiom'the side of the adding key stem 230 above the stud 253 upon the adjacent type-key 1' would 'of course serve the purpose .of causing the dey pression'of the adding ke'y to carry the typestored in the adder mechanism. Adding n is useless, however accurate it may be gen-.`

mechanism which 'is not practically infallible erally. To insure absolute accuracy, I pro vide means to lock the two keys together at the depression of the adding key, so that the type-key cannot be thrown ahead of the addmg key by a quick or violent partial depression of the latter and the escapem'ent mechanism of the machine be ythereby operated and the paper carriage shifted without first fully depressing the adding ke and adding its value upon the registering wlieel of proper denomination in the addingv device. Any suitable automatic couplin or locking de# vice between the adder an type-writer de. loyed in carrying outmy.

,vlees may be em invention, but t e bell-cranks described', and coperating parts, are simple and efiiclent. f

From the above it'will be seen that 'it is essential for the effective working of the apparatus that the two keys shall'upon the actuation of an adder key be so'connected that one shall inevitably move with andl only with the other and also that after the movement of an adder key`begins it shallnot be capable of a return movement until its full stroke is completed. When therefore in this specification and in m claims I make use of the terms connecte "-locked together and positively locked, I do not mean a mere.

- contact between the parts insuring a partial simultaneous movement butpermitting one part to be capable of an independentmove-- ment, but I mean an absolute connection' of the vtwo 1n such manner that one cannot move Without the other after the movement of the adding key begins and the relation of the two is preserved through the movement of the adder key. .A

The generaloperation or'mode of use of f fermer the add-inlg mechanism of my machine is as v he position which it-is desired the verticalcolumn of iigures shall occupy upon the sheet; of apex having beenfirst determined, the ja der A. i's slidalong .the papercarriage to a position-opposite `such proposed 'column of figures, `and adjusted to 'exact position for the respective pinions 214 to registerwith thesector 215 when amounts are being printed in the corresponding denominations in -thefcolumns of iigures upon .the paper. Thus, if it be vproposed to print' the. column' of iguresin suchv position that the units'ofvcents shall be opposite the gradiea'tion 6() on scale bar 98,. the addi-r` will be adjusted for the'fpinion 214 of itsunits of cents registering jwheel'to registerwith the sector 215 when the paper-carriage is in position transversely of the machine to print a iigure inthe units of cents column at 60.

vThe printing may then be begun in anyv higher denomination in the column by rst moving the'paper-carriage the proper distanceto the right, and as the adding keys arefthen successively operated to print the desired amount the paper-carriage will ad.

vance step by step toward the left and carry 'the pinions 214 oi4 the adder successively in-to line or register with the sector 215, and l while in line with each pinion the sector will actuate such inionand the corresponding movement 'of the adding key, and the papercarriage will move the adder to the left to the next lower denomination upon the return up stroke of the adding key, while the sector is disengaged from the pinion, as heretofore described. l

.reglstering w eel during the downward To facilitate theadjustment of the vadder' A in the manner and for the purpose above described I provide a pointer 257 projecting forward from a plate 258 secured to a iixed cross piece 259 of the machine, Fig. 1, which pointer coperatesy with the registering wheels 213, or a corres )ending scale uion the/top plate of the ad er casing, to ai in determining ythe exact location of the adder. Whenv the adder is adjusted transversely of the machine untily the .pointer 257 stands opposite any given registering .wheel 213 Athe pinion 214 ycorresponding to such wheel `will e in line or register with. the sector 215, ready for actuation thereby. A pointer 260 projects from the rear `side of theplate 25S over the scale-bar 98 on-the paper-carriage,

to determine the positions of the latter' transversely-of the machine, as usual. In adjusting the adding device to print' a col-r gumn of igures with units of cents at 60,`as

justed longitudinally of the paper-carriage until the units registering wheel 2 13 is brought opposite the pointer 257,'which adjustment o the adder may be eifected either entirel l by the screw rod '206, or by rst releasing 1t from such rod by turning the rod 208 and then sliding the adder along the rod by hand, and' then rengaging it with the screw rod and effecting its nal adjustmentby-turning said rod, as .heretofore described.

After the adder has'been adjusted for the printing of the column of figures in the desired position upon a sheet .of a er the Y paper-carriage will be slid tolits rig t hand mit of movement, and the desired memoranda be written inthe left hand' portion of thc line with the regular type-keys of the machine.v When 'such memoranda have been completed the paper carriage will be spaced or otherwise moved onward to the left until the desired denominational column or s ace in the columnof figures is brought to t e printinv point. The amount to be entered will t en be printed by operating successivelythe proper adding keys, and be thereby simultaneously added upon the adder A. The paper-carriage will then be returned to theright, and the platen roller turned to advance thesheet of paper for another line, as usual, and the operation be repeated. When a sheet has been'iled, or the lower end of a column of memoranda and figures of desired 'length has been reached,

the sum of all the amounts lin the column ofy figures will be displayed in the top of the adding'` device u on lthe wheels 213, so that such sum may e ascertained vat a' glance without the necessit for any mental calcu lcolumn beprinted with the adding keys, so

that when thel end of the second colhmn'. is

` reached the wheels of the adding device will display the sum of the amounts in both columns, which total may be printed at the foot ofthe second column with the regular type-keys of the machine, and carried forward to the head of a third column, and so on to any extent desired, the'adding device preserving a total of all the amounts printed y the adding keys until its wheels are reset to zero or .initial position in the manner hereafter described.

The two right hand keys in the row of adding keys, Fig. 1, bearing re pectively a ci-l pher and a period 'or decima point, are provided merely for convenience, to enable the of the machine.

complete amount (including ciphers and decimal points) to be printed with the keys in the rear row alone, without resorting to the corresponding keys in the regular keyboard It will of course be understood that these two keys have no mechan- `engin '7 icalv connection with the adding device, asy

indicated in Fig. 3, but are simply coupled suchadding keys to print ciphers and deci mal points in the column of figures.

.to the corresponding type-keys when de- In the present instance, as shown'in Fi s.

1, 3 and 4, I have left spaces between e tens of cents and units of dollars registering wheels,and between the hundreds of dollars and thousands of dollars wheels, and between the hundreds of thousands and millions of dollars wheels, so that it is necessary to operate the space bar of the machine in passing from the millions denomination to the hundreds of thousands, and from the thousands to the hundreds, and t-o operate either the space bar or the decimal pointr key between the unitsof dollars and tens of cents Wheel.v I have arranged the registering wheels in this manner because of the common practice of printing amounts with such spaces between the several denominations in adding machines now in very extensive use, but it is not in any Way essential to and forms no part of my invei'ition, and so far as the latter is concerned the registering wheels may be arranged immediately adjacent each other sothat any amount may be printed and added by successively operating the adding keys immediately after one another, without any operation of the space bar or decimal point key, as will be readily understood.

ioov

The provision for adjustment of the adder A longitudinally of the vpaper-arriag'e not only enables a single column of gures to be printed at any desired point transversely o'f the sheet of paper, but' permits the printing of several columns successively, side by side, and the addition of the amounts in all of them upon the adder. Where, however, it is desired to carry out the same memoranda into several amounts in different columns it will be more convenient to provide the machine with a corresponding number of adders A located side by side upon and adjustable or non-adjustable longitudinally of the paper carriage. The adders A are comparatively inexpensive and may be readily put in place upon and removed from the paper-carriage, so that each machine may be conveniently provided with extra addersV for use when necessary.

In its details the adder A maybe of any suitable construction, the only essential beindg that it be provided with driving pinions a apted to be successively engaged with the 60 'the intermediate tcrmediate its registering wheels so asv to beveled 'shoulders inner end of a spring pressed arm 264, which serves to aline the registering wheels, with their numbers properly exposed at the' slight opening in the top of the casing, and also to prevent backward movement of the parts. The transfer pawls 265 also coperate with the ratchets 263, there beinl one of such pawls for each registerin whee except the units wheel, and locate between. the intermediatev gears 261 of the respective wheels. .their -lower ends to the front ends of levers 266 whose rear ends project between and be.

side latch arms 267 hung at their upper ends upon a rod 268 and pressed forward at their lower ends by springs 269 and provided with or hooks adapted to catch under lateral projections or Alugs 270 upon' the rear ends ofthe pawl levers 266 and support the rear ends of said levers in elevated position, as in Fig. 10, against ythe stress of springs 271 tending to press the front ends of t e levers upward and depress their rear ends. The transfer pawls 265 are provided with forward extensions at their lower ends,

. lagainst studs 272 upon which the outer ends the springs 271 bear and thereby serve not only to press the front ends of the levers 256 upward but to press theupper ends of the pawls 265 inward and' maintain them in engagement with the ratchets 261. Each of the depending latch arms 267 is provided upon its forward side with a beveled tooth or projection 273, Fig. 11, normallyprojecting lnto the path of travel of two diametrically opposite pins 274 upon the adjacent ratchet 1,261, with the result that at each half revolution of such ratchet the latch arm 267 will be swung rearward and its lower end be disengaged from the lever 266 which carriesthe pawl 265 coperating with the ratchet wheel of next' higher denomination, thereby releasing saidpawl and permitting its spring 271 to throw it upward and cause'it to turn suchregistering wheel one step or unit of distance. The upward movement lof the pawl is limited by contact with'a rod 275 extending transverselyV across the forward side of gears, and which also serves, owing to the beveled upper end of the pawl, to loc the pawl in engagement with 1the ratchet and prevent any overthrow of the atter;l

These transfer pawls are pivoted at.

The pinions 214 and 262 have ten-y teeth each, while the intermediate gears' 261 have twenty teeth each, so that each full revolution ofthe pinion 214 imparts a half' revolution to the corresponding intermediate gear, and the latter imparts a full revolution to the corresponding registering wheel.l

upon theratchet 261 has swung theflatc'h arm 267 rearward tol its limit of movement Ibut' has not cleared the point -o the tooth 273 upon said arm, and is still holding said arm in rearward position. As soon as the pin clears the point of the tooth (which it does before the parts come to rest with the registering wheel which isgeared to said ratchet in zero'position) the latch arm will be swung forward to normal position in contact with a suitable rod 283. When the rear end of the pawl lever 266 is subsequently lifted its projecting lug 270 will ride upward over the beveled forward surface of the hook of the latch arm and pressthe latter rearward until it clears the point of the hook, whereupon the latter will spring forward under the projection 270 upon the lever and support the latter in normal position. For the purpose of thus lifting the transfer pawllevers 266 to normal eration of the device I provide resetting means for such levers which isA actuated at position after each op-l j 75 t will be understood that in the position .of the parts shownl in Fig 111 the rear pin 274 'each operation of the line-spacing mechanism of the typewriter, As shown in Fig. 5, the line-spacing lever 101v is provided upon its under side with a gear-toothed sector276 which mesheswith a pinion 277 fast upon the side of a cam 278 which cooperates with a roller 279 carried by the rear end of a lever 280 which has depending from its front end a link 281 connected. at its lower end to the side arm of a bail 282, Fig. 4, whose cross bar extends entirely across the machine in the position relatively to the adding device shown in Figs. 1 and 11. At each operation of the line-spacing lever 101, therefore,

the rear end of the lever 280 is depressed and` the bail 282 swung upward, thereby returning to normal osition all of the-pawl levers 266 which have been released fand thrown downward by their springs at the precedingV operation, and causing their lugs 270 to be` rengaged by the hooks of the latch arms 267. l f

To permit the bail 282 to be swung upward and the transfer pawls reset without moving the platen roller and advancing the paper, when desired, Improvide-a lever 1011 adjacent the lever 101 Fig. 5, whose front end is adapted tobefthrown forward beneath a stud 101b upon the side of the pawl 102 when the real-end ofthe lever 1 01 is pressed forward toward the lever 101, and

thereby prevent the pawl from engaging the ratchet 103 when the two levers. arel then swung rearward vtogether to operate the. pawl-restoring bail 282.

Each of the ratchets 263'has pivoted to it a spring-pressed pawl 284, Fig. 11, which eooperates with the .longitudinal groove in the shaft 207 upon Which said ratehets' and the intermediate gears are mounted. By. turning this shaft forward,l in the direction in which the registering wheels normally turn, therefore, all of the registering wheels may be picked up and carried forwardto initial or zero position by a complete revolution of the shaft, in the usual manner of such resetting devices.
