Sp'eccation of Letters Patent. Application filed October 14, 1904. Serial No. 228,414.

Patented March 16, 1909.

T0 all whom 'it may concern: I

Beit known that I, FREDERICK L. FULLER,

a citizen of the United States, residing 'atz Trenton, in the county of'Mercer and State of New Jersey, have invented a new and useful Cash-Register, of which the following is a specification.

The present invention has for its obj-ect the provision of a new cash register having a series of motor-driven indicators, a like series of banks of keys therefor which limit the AeX- tent of movement (to indicating osition) yof their respective indicators accor ing to the keys depressed, a like series of detents which in normal position prevent movement of their respective indicators to indicating position but are withdrawn from such position by the de yression of keys in their respective banks, an another series of detents normally locking all of the indicators against `move.

ment to indicating position and which are all withdrawn from such position by the depression of a special key; these several elements being so constructed and combined that on the (e ression of a key in one bank, or in each o two or more banks, followed by the depression yof said special key, the indicator or indicators corresponding to such bank or banks will 'be released by both sets of detents and be driven to indicating position, in which position they arev arrested by the keys -depressed, while the indicators correspondin to those banks in which no keys Aare depresse will remain in 'their zero or normal positions. With these mechanisms there are combined, among 'other things, registering mechanism for `totalizing lthe amounts of the transac tions, printing wheels by which the several transactions are printed on a strip 'of aper, and also a lever for restoring the indicators and printin wheels after one operation to their norma' or zero positions before the next operation of the machine and which also' serves to put under tension a spring Ioperating, among other things, a printing-platen, a drawer-lock and a gong, and also'operating 'a member held in normalL osition by a detent. controlled by the specia key aforesaid and which member controls the operation ofva shutter mechanism', and when moved by said spring from normal `position prevents withdrawal or reoperation of said special key (and therefore reoperation of the machine) until this member, the indicating wheels land printing wheels are returned to normal or zero position.

In the accompanying drawings Fi re 1 is a plerspective view of a machine em odying t e present invention. Fi 2 is a front elevation ofthe machine with t iecasing and the banks of keys mounted therein removed. Fig. 3 is a rear 'elevation of the s me.

',Refgerring to said drawings, the several mechanisms of. the machine are mounted upon a base A in the lower art of whidh-is rawer B. The e which supports v mounted a sliding mo framework ofthe mac the workin arts, consists of three upri ht partitions ,Ik E 4(see Figs. 2 and 3)..l'i'xe to the base and held in vertical position tierods F, G, H, these working parts, partitions and tie-rods being inclosed by a suitable cas'- in' which is shown in Fig. 1.

' tions C, D, whilethe indicators, also .consistJ ing of wheels 68, for the rear of the machine are located inthe right hand half of the ma-v chine between partitions D, E; all of these -wheels being loosely mounted on a shaft 63 extending entirely across the machine. In the right hand half of the machine isi also located the registering mechanism, while outside partition E is located a ,printing mechanism, inclosed by a slllpplemental cas-l artition All of, these ing I hinged to e fully described hereinmechanisms will after. For the present the description will, for convenience and clearness, be mainly confined to the mechanisms contained in the left hand half of the machine. In the front of the casing, in this part of the machine, there 1s mounted a keyboard comprising six banksof push keys 23 and Va single special key 42, whlch latter controls the indicating, reglstering and printin oplerations, as will hereinhe eys in the bank at the left of which are sometimes called system keys, bear-letters and abbreviations indicating, res ectively, the salesmen and the character o the transactions, while the keys in the other five. banks bear` numerals representing amounts', in units, tens, etc. counting from the right of Fig. 1. The .keyboard frame in which these keys are mounted is made up of a series (seven in number) of castings 14 (see Figs. 1, 4, 6 and which are I-shaped in cross-section,` or, m other Words, have inner` and outer flanges:

, 1.7, 18 connectedb 'a vertical web portion, parts of which may e bored o r cut out for the sake of lightness, `as shown in Figs". 6 and?. These castings 1^. are held together, with the adjacent edges of their anges 17, 18 in con- .tact with eachother, by tubes 1.5' assing through openings in the upper an, lower ends of the several castings, and are secured in position in the machine b rods 16 through the tubes 15 and t 'e ends o which enter` openings in the vertical artitions C,-

D,.in whichl they are ri idlyl lheld in any Suitable manner. Suitab e slots or openings are provided in the left hand edges of the flanges y17,418 of these castings 14 for the rece tion of the stems 19 of the keys 23, and

of one these castings, namely, t at to the right of 1, additional slots forfopenings lprovided /forthe reception of'the e special key 42: The ste of all Y savent turning of the keys vwhile permitting -chine right hand edge of the Han es 17 18- 4o keys are non-circular in crossection4 salesmen and character of thetransac'tions are alike in construction, a description of one bank and the keys therein'will suffice for an understanding Lof, t'e construction of all.

Referring, therefore, to Fig. v6, (the keys` shown in which 'hap en to be the system keys shown' at the eft of Fig. 1) it will be observed that each of the castings 14 is arcshaped, considered lengthwise, and also that the slotsv or openings 1n the flanges 17, 18 thereof for thevkey stems 19 are radial, so that the key stems 19 in eachbank converge toward a common point, namel a 'shaft 2 journaled in partitions C, D, r and upon one en d of which, projecting outside the maging, is fixed an oscillatory lever 3, herein er more full referred to, and which on each operation o the machine is given a complete reciprocation or oscillation lfirst rearward and then forward.' -The stem 19 of each key, it will be observed, has coiled about ita spring 20, one end of which is secured bya screw 21 to the stem and has its other end bearing against the outer surface of the ange 17, so that its tendency is to force surfaces of thel adjacent flanges 17 so as to.I

limit 'such outward movement of the ke7 One projecting end of this pin 22 (name that on the left hand sidev of the stem 19) coacts with the curved arm 30 of a det'ent 28 loosely .mounted on a rock shaft 27- while its opposite end coacts with a ke locking platev 1,2 loosely mounted on' sha t 2,-the constructionr andfunctions of which locking plate and detent scribed in detail.v

In the left hand half of the machine. there are rovided for each bank 'of keys, in addi- 'tion to the indicatorwheel 62, and theflock-fing plate 12 and detent -28 just referred to,

a l gear-24 loosely mounted on a'shaft 25 para el tof sh fts 2 and 63 and'xieshing with a pinion 61 s ast totheside o the indicator wheel 62 so as to-drive the latter-to indicating position; a -segmental gear -11 mounted loosely upon the shaft 2- and meshing with the.` ear 24; and a s ring 47, one end of whic is connected wit the gear 24 and the other (as shown in Fi i 6) with a projection will be hereinafter de'-` the key outwardly. Apin 22 passes through upon the hub of the ocking plate r12. The

giears 24 not only drive their res ective. inicatorwheels 62, but also simu taneously v drive the companion or corresponding indi` annosoy cator wheels 68, and the registering and printing wheels, machine, as hereinafter described. The functions of each spring 47 are two-fold,

namely, to drive .the indicator wheel 62, through the gear 24 and inion 61, to indi- Ieating position, (each in ieator being thusprovided with va separate or independent motor) and also to retain the lockmg plate 12 yieldingly in the depressed position 1n which 1t is shown in Fig. 6, in which position beveled portions of its periphery rest against the gear 11., and further by a detent 26 (one of which is provided for each indicator wheel 62) which normally engages the gear 24. It

follows, therefore, that, in order to secure such movement of the indicator wheel 62, both of these detents 28 and 26, which are independent of each other, must be movedl from their normal positions. This movement of the detent 28 is effected by the de- )ression of a key 23, in the following manner. he curved arm 30, heretofore referred to, of the detent 28, it willbe observed, extends along the left hand side of the stems 19 oftlie vengage thethus rock the loe ing lplate 12 u 'said hoo Varm 30 (see keys 23, as viewed from the front of the ma- -ch1ne, and in alinement vertically with the i ends of the pins 22 glrojecting from that side of the stems 19, so t at, u on the depression of any of the keys 23 lint e` bank, such pro-v jecting end of the pin 22 thereof will engage and depress the arm 30and through it rock the detent 28 upwardly and out of the path of movement of the pin 29 on the segmental gear 11, against the pull of'a spring 31 fast to the eastirlig 14 and to the free-end of the iv. 6), The key thus depressed is held in its depressed position and the detent 28l therefore held in its raised position out of the path of movement of the pin 29, by the locking plate 12, which, for this purpose, is provided, below its peripheral beveled portions before referred to, with notches or hooks 13 equal in number to 'the keys in the bank. Upon the depression of a key 'of thepin22 which projects 23, that end from the ri ht hand side;of the stem 19 will veled ortion-in line with it and wardly against the plull ef the spring 47 unti the pin 22 comes in 'ne with the undercut portion of the notch or hook 13, whenthe spring 47 will rock the lplate`12 downwardl and thus cause 13 to snap over t e end of pin 22 and lock the key in itsdepressed position. With the key thus depressed, the opposite or' left hand projecting end of the pin 22,y

in the right hand half of the be described.

bein still engaged ,with the arm 3, will hohl the etent 28 in its raised position out of the path of movement of the pin 29. Rotation n of the indicator wheel 62 is, however, still prevented by the llocking engagement, with gear24, ofthe detent 26, which is disengaged vtherefrom bythe depressi'onof the specialA 42 through connections 'which will no'w It ma be noted, in passing, thatuntil such specia key 42 is so depressed no indicating or registering-operation takes place, so that if a salesman should discover that he had made an error in depressing a certain key 23, he `may correct such error by depressing thc proper key in the bank, when the locking plate 12, rocked upwardly bythe kejr /second key depressed, will .release the first one depressed and hold the second one in its depressed position. After such speeial'key 42 is'depressed, however, no such correction can be made as, by the depression of this key, locking devices,-` which will also now be de# scribed, are thrown into engagement with the locking plate 12 so as to .irevent fnovement thereof, and therefore the depression of any 'other key 23, either in the banks in which keys have been depressed or in those banks in which no keys have been depressed.

, The detent 26 for each bank of keys and indicator wheel 62, as before stated, is fixed to the rock shaft 27 and this rock shaft 27 is, as shown in Fig. 7, provided with a curved arm -44 which enters a cut-out 4B in one side of the stem of the special key 42 that when said special key is depress d it will, through the arm 44, rock the sha t 27 and thereby raise, `-ormove from locking position, the detents 26.0f all of the indicators and thus ipermit the springs 47, of those banks in w ich keys 23 have been depressed and detents '28, therefore, moved out of the path of the pins or studs 29, to rotate the indicator wheels 62 of those banks to indicating position, the special key 42 and the detents 26 being held in this position throughout the movement of the'indicator wheels 62 vby'means which reference to Fig. 6, are of suchlcngth that I when depressed their 'lower ends will project into the paths of movement of .studs or projecting laterally from time),4 upper ends of t e segmental gears 1 1.

Of course, -it

will be understood that, as th'e several indi-v f cator wheels 62 are inde iendently driven,

theyr will be rotated to dii er'ent degrees acl l A cording to the keys depressed7 in their re,- spective banks; for example, one may bo arrested b the first key in one bank (counting from t e top) if that is the key depressed, another by the third key in another'bank,

l another by the fifth key in a third bank, and

lt willalso be understood that in those banks in which no ke 23 is depressed the detents 28 controlled y such keys 23 still remain in the pathsof movement of the studs or pins 29 of the segmental gears 11 of those banks and will, therefore, prevent rotation, by springs 47, .ofthe gears 24 and indicator wheels 62 of those particular banks, notwithstandin the detents 26 of those banks have, Wit the detents 26of the other banks, been .disenga ed from the Wheels 24 of those banks by t e rocking of shaft 27. When the indicator Wheels 62 are thus prop'elledby their springs 47 to indicating position, as just described, the correspondin or com anion indicating Wheels 68 on the right hand) side of the machine are also propelled to indicating position by the gears 24 of the respective lndicator Wheels. 62, through connections consisting, for each gear Wheel 24 and indicator wheel 68, of a pinion 65 meshing withl ear Wheel 24 and fast upon a shaft 64 which extends entirely across the machine and ,has fixed to it a second pinion 67 meshing With'agear 66 (like gear 24),. mounted loosely upon 'the yshaft '25 and meshing with a pinion lfast to the side of the indicator Wheel 68; The several shafts A 64 are arranged parallel to each other the several pinions thereon are arranged in different verticaly planes relatively to each other for engagementby the gears 24 of the several banks as shown in. Fig. 3;v and the several pinions 67 thereon for driving the several mdicator wheels 68 are likewise arranged upon the shafts64 in different vertical planes relatively to each notherfso as to mesh With the'several gears 66 through which, and the pinions 61, .they 'drive their respective indicator Wheels 68. In other words, .the arrangement of the shafts 64` and the pinions 65, 67 thereon is such that the units indicating Wheel 68 (the first one toth l'eft of the partltion D, Fig. 3) will be driven from the ear 24 which drives the units indicating W eel 62 (the first one to the right of the'partition D, Fig. 3); the tens indicating Wheels 68 (the second one'to the left of the partition D, Fig. 3) by the gear 24 Whieh drives. the tens -indicating wheel 62 (the second to the right of the partition` D, Fig. 3), and so on; lthe several indicator Wheels 68 ytherefore being drivenf by thesame means as andsimultaneousl with the indicating Wheels 6-2 so as to ma re the'same indication at the rear of the machine as that made at the front of The special key 42 is held in its de ressed position, and the detents 26 therefore eld in their Withdrawn positions, While the indicator vvaeels 62 are moving to indicating position', by a segmental gear 33 mounted loosely upon the shaft 2 and driven b a inion 34 fast on a sleeve 48 on the end ofyasfiaft 35 journaled in the partitions D, E (see Figs. 3 and 7).

Because ofthe play provided between the cut-out 43 and the arm 44 as the key 42 is de ressed, said key must, in order `to depresst e arm 44 so asto disengage the detent 36 from the Isegmental gear 33 and detents 26 from the gears 24, be so far depressed that the channel 46 in the lower end of said 'key stem will p lane of rail 45, withthe result that the soli portion of said :key stem above the channel 46 will be in line with the rail 45 and thereby prevent movement of the lever v3 and shaft 2 until, on

` the removal of the finger lof the operator from -the special key 42, said special key is moved outwardly so that the lower wall of the cut-out 43 therein will engage the lower or inner edge of the arm 44 atwhichtime the channel will be in line with the rail 45. When the channel 46 is thus -in alinement with the rail 45,-it will permit thepassage through it of the latter, so that the handle 3 and shaft 2 ma be moved rearwardl y. When the rearwar movement of the hand e 3 is'compleed, the rail 45 will have passed out of the channel 46 so that, 'when the shaft 27 is rocked by the s ring 27, as heretofore described, the specia ke 42 may be moved from itsl depressed positlon to the projected position in which it 1s lshown in Fig. 7. Such premature rearward movement of the lever 3 1s also prevented by sleeve 48 and shaft 35 through a locking device controlled thereby and engagingthe shaft 2. This locking device conslsts of a ivoted bell-crank lever 53, the upper end o which is backed up by a v spring 5 3 l tendingto .force it/toward the shaft 2 and into engagement with a tooth 54 thereon, land the lower end of which is normally engaged by a cam 52 on Lshaft 35 which, in the positionof restvof said shaft, holds the opposite endv of the lever 53 out of engagement with the tooth 54 (see Fig. 9). This shaft 35, it will be remembered, is given a complete revolution by sleeve 48 (through .clutch 51) when drivenby spring 49, this taking place, as before described, when detent 36 is-disengaged from .the notch in segmental ear 33. As soon as the detent 36 is thus isengaged from the notch in the upper end' of segmental gear 33 and the rotation of sleeve 48 vand pinion 34 begun by lspring 49, the shaft 35, rotating with said s eeve and pinion, will move its cam 52 from under the lower end of lever` 53 and thus permit the spring to throw the upper end of said lever into engagement with the tooth 54 on shaft 2, thereby -preventinfr rotation of said shaft 2 until said shaft 35chas made a comthe lower end oflever 53 and withdraw the upper end thereof vfrom engaffement with tooth 54, when the lever 3 andshaft 2 will be free to be rocked rearwardly. During the revolution of shaft 35iit performs the additional functions of with'drawing the lock 56 from the money drawenB and form of abell-crank lever 59. The first of these functions is performed by a cam 55 on shaft 35 which, when, said shaft, nears the completion of its revolution, engages one end of a bell-crank lever 57 fixed tolta shaft 108 and, lrocking the other end thereof upwardly, withdraws the bolt 56 from. the drawer. The second function is erformed by a cam 58 on shafty 35 which, w en said shaft has about com leted its revolution, engages and trips f the ever 59, causing-it to Vstrike the gong beneath'it. This hammer-lever shaft 108 is journaledin artition E, with one end projecting into tl e casing I, and, as will hereinafter appear, assists in the 'operation of the printing mechanism. Means are also proafter a partial movement thereof in either direction. The means rovided for this purment 4 hereinbefore referred to, having two sets'of reversely arranged ratchet teeth 6 and a double-ended E wl 7, pivoted at 8, and engaging these teet The pawl 7 is provided near one end with a lug9 of wedge shape against the upper and lower sides of which a .spring presse l l t 'e purpose of maintaining t e pawl 7 1n engagement with one or the other set of ratchet teeth 6. When the operating handle 3 is being then in engagement with the forward pose (see Fig. 5) consists of the'ratchet segdog 10 is ada ted to bear for plete revolution, when cam 52 will rengage I tripping the gong hammer, which is in the ff vided for preventing the return of the lever 3 with a projection. 5 midway'between them,

thrown rearward the forward end of pawl 7 set of ratchet teethl will prevent any forward movement of the lever until said rearward movement is completed.l When such mover-nent is completed the projection 5 on ratchet segment 4v will engage the forward point f thepawl and thus raise the rear oint of the pawl, the lug 9- then forcing the og--lO backward until the upper end thereof snaps under the lug 9 so as to hold the rear ,point of the. awl kin engagement with the rear set `of rate et teeth throughout the forward or return movement of the lever 3, at the end of which the projection 5 will again reverse the pawl 7.

I The registering mechanism will now be. described. i

For the five banks of keys bearing numerals there are five register wheels 74 bearing numerals representing amounts in units, tens, etc. 'counting from the`right in Figs. 2 and 11, there being no register wheel for the sixth or system bank of keys. Thel units register wheel 74 at the extreme right of Figs. 2 and 11, is operated by the gear 24 of the units indicating wheels 62 ,68; the tens register wheel (which is next in order to the units register wheel) by the gear 24 of the units indicating wheels 62,68; and so on. In addition to these five register' wheels, two others, 90, 91, are provided, shown at the left in Figs.4 2 and: 11, to which amounts are carried from the last of these five register wheels.

The five register wheels operated by the gears.

24 are identical in construction, and the connections by which they are driven from their respective gears 24 are also identical. They, as well, as the two additional register wheels, 90, 91 referred to, are all mounted loosely on a shaft 71 journaled inthe frames D,`E, and

each has two sets of numerals from'O to 9 ar'- ranged one behind the other on its eriphery. Each is also provided with a rate et.73 enn gaged by a spring pressed paw] 72 pivoted in '7 4, is di'iven b the side of agear 7 O also loosely mounted on shaft 71 and'by which 'the register wheel is rotated "when registering. l The gear 70,

which has twenty teeth to correspond with' the twentyJ numerals onthe register wheel the shaft 64 and gear 24 (of thejbank to w rich the register wheel corresponds,') as the latter drives its1 ' indicator wheels 62, 68 lto and from indicating position, asbefore described. The connections through which the gear 70 is so driven consists of the shaft `54 (driven by gear 24"through pinion 65), a pinion fixed to said shaft intermediate its pinions 65, 67, and a gear 69 mounted loosely 'on shaft 25 and meshing with said v gear70. ,lWhcn the shaft 64 is rotated by gear 24 to move itsI indicator wheel 68 to indicating position, the gear 7 0 will be rotated thereby in the directionofrthe arrow Fig. 15 and thrcugh itspawl 72 and the-ratchet 73 rotate register wheel 74 ay distance 'correspending to themvement of the indicator "wliefel, thus registering the amount ifidicated 7 and force it downwardI vthe machine desires to p on the rotation of said shaft 71 in by the latter. the opposite direction to return indicating wheel '.68 to zero orv normal position, gear 7 0 will be rotated in the vopposite direction to that indicated by the arrow iii Fig. 15, and its pawl 7 2 will slip idly ovei' the teeth of ratchetl 73, leaving the register wheel 74 in lthe position lto which it has been moved.

The register wheel 74 is held in this position bv a spring escapement 76 (see Fig. 9) pivotprevents overthrow of and accurately p ositions the register wheel. As the indications onthe register wheels are readfrom the front of the machine and not (as is thev case with As the-shaft 64 i-s turned in' a ly mounted on shaft 25, and which alsothe indicating wheels 68) from the rear, it

will be understood that the gear69 at the left of Fig. 3 is the onewhicli operates the lunits register wheel 74; the next gear 69 to the right thereof the one which operates the tens register wheel 74, and so on.

The register wheel shaft 71, which, as before described, is journaled in the .frames D, E, is normally prevented from rotating in the direction 1n which the register wheels rotate by an arm 117 having a tooth entei'-` ing a recess in the hub of a ratchet 119 fast to the shaft 71, as shown in Fig. '10, and rotation `lisaid shaft 71 in the opposite direction is al ays prevented b the teeth of said rate hereinafter described, for withdrawing the arm 11.7 from engagement with the recess in the hub of ratchet 119 so that the shaft 71 may be rotated b hand (for which purpose it may be rovi ed witha knob or other suitable device at' itsright hand end) -inhthe direction indwhich the register wheels are rotated. during the. registering operation so 'as to rerset said register wheels to their zero positions whenever the iro rietor or user of o t s." The means whereby, this direction, said register Wheels are returned or re-set to their zei-o positions, consist of a longitudinal groove or slot 78 on the ,shaft 71., which, when said shaft is rotated,

awls.

as just described, will lengage spring 77` carried b the several register w eels, as shown in iigs. 12 to 14, and 4rotate said register wheels to their zero positions. As, the register wheels, yin the registering opefation, ai'e rotated on the shaft 71, these lpawls.77 will bear upon the surface of said an arm 120 engagingV et 119; both of these arms 117, 120 `being mounted u on Athe shaft 25. Means are provided, an will be shaft and pass the .groove or slot 78, but

when the shaft is rotated said groove or slot 78 will, b`y engagement withthe spring pawls '77, pick up the several register Wheels and rotate them to their Zero positions.

The registering mechanism` also includes devices for carrying amounts from one register' wheel 74 to the next higher register wheel, which devices will now be described.

\ cam' 87 on the shaft 88, so4 that when said register wheel adistance equal to one tooth :x tated, with sleeve 80, by a cam 87 on a shaft upon the right vhand side of the next higher of notches 84, 86, adapted to be engagedby a moved from this position to or beyond the Upon a shaft 79, parallel to the shaft 71, are loosely mounted five sleeves 80 (one fori each ofthe five register wheels 74 driven by. i the shafts 64) andeach of these sleeves is provided at its -right hand end with a star wheel 81, and at its left hand end with a star wheel 82, bothrigid with the sleeve. The star wheel 81 is ada ted .to be periodically engaged and rotateri together with sleeve 80, by`a pair of fingers 85 projecting from diametrically op osite points of a sleeve or hub at the le t hand side of one register wheel 74, while the latter (viz: the star wheel 82) is adapted to be engaged and ro- 88, and when so rotated to engage a gearI 75 register wheel 74 so as to.rotate the latter. one tooth or numeral. Shaft 88 is provided with five cams 87, one for eachof the sleeves with its pair of star Wheels 8]., 82. The star wheel 814 has four teeth and star wheel 82 a like number of teeth, while sleeve 80 is provided circumferentially with four pairs spring detent 83 fast to the tie-rod H. Normally, as shown in Fig. 1.6, the detent 83 is in engagement with one of the notches 84 and when 'the sleeve 80 is in this position one of the teetlyof the star wheel 81 lies in the ath ofmovement of the fingers 85 of the ower register vwheel 74.

When thel lower register wheel 74 has been rotatedvnine teeth or numerals and is being 0 mark which follows, one of its fingers 85 which then 'happens to be in its path of movement and rotate said star wheel, from the position shown. by full lines to the position shown by dotted lines in Fig. 16, thus rotatleft hand end thereof. When the sleeve 80 has been thus rotated, the detent 83 will drop into therear .notch 86 and retain the sleeve and the star wheelsSl, 82-,in the position to which they havebeen rotated or set; this notch 86 being made somewhat deeper than'the notch 84 so as to retain'the sleeve and its star wheels firmly in this set position against any tendency to 'displace it duc to jar or vibration of the machine; When a tooth of the left hand star Wheel 8.2 will be brought into the `path yof movement of its shaft is rotated in the direction of the arrow, Fig. .16, this cam, enga ing this tooth of the star Wheel 82, will furt er rotate 'the sleeve 80 and itsstar wheels the balance of a quarter revolution with the result that the next following tooth ofthe star wheel 82 will engage the gear 75 of the next higher re ister wheel 74 and thus rotate said gear whee and.

or ne numeral. The five cams 87 are arf" ranged spil-ally upon the shaft 88 so that when said shaft is rotated the cams 87 will operate' successively, sothat the sleeve 80 aiiritar Wheel 82, which carry from the units register wheel to the tens register wheel, will fviirst be operated, then the sleeve 80and star wvhcel 82 which carry from the tens registerv Wheel to the hundreds register wheel, and so on. This successive operation f the sleeve 80 and star wheel 82 provides for the carrying from one registcrwheel to the next highest bnc, not only in those cases where a register wheel is moved from 9 to 07- the registering'operation, through its gear 7 but also in those cases where a register wheel isso moved during the.; operatiorpf eairyiilgtfg For example, if the starjwhjel 82roithemn`its` registering wheel beoperated by its -cam 87 to carry one to the tens registering wheel, and it should then happen. that the movement of the latter is from 9 to 0 one of wheel on the sleeveconnecting it with the hundreds registering wheel and thus position the star wheel 82 thereon for engagement and rotation-by the next cam and consequent vengagemerlt with, and operation of, the gear 75 of the hundreds registering wheel. v

The shaft 88 is rotated in both directions4 by the lever 3, through the shaft 2 and segmental gear 37, which latter, as best shown in Fig. 7, meshes with a pinion 89 fixed to the left hand end of the shaft 88. As the 'lever 3 is rocked rearwardly, the segmental gear 37 will rotate the shaft 88 in the direction indicated by the larrow in Fig. 16, and the cams 87thereonwill successively engage the star wheels 82 that have been set for such engagel"ment, or become so set during the carrying,

as just described. When the lever 3 .is rocked forward, said shaft 88 will be rotated in the opposite direction, the cams 87 then passing under the teeth of star wheels 82 Without enga ing them, and the several star wheels and t eir sleeves' 80,being' then in normal position, in which position they are .held by the engagement of the spring de' tents 83 with notches 84 on said sleeves (see Fig. I l r i I v -Thus far the description of the carryin de- ;vices and the carrying operation has een limited to the five register wheels which are actuated by the gears 24 and shafts 64, as just described, except that it has probably been observed that the sleeve 80 with its star wheels 81, 82 which is set by' theffth register wheel 74, i. e., that'oneI of the iive which has the highest denomination, carries from that wheel to the sixth re 'ster wheel 90 (count- Iing from the right) s own in Fig. 11. For

to t e seventh or last wheel 9U vof the set (shown at the extreme' left in' Fig.;11),:any

suitableIform:of;carrying:device:may be proits fingers 85 will engage and rotate the star the urpose of carrying from this latter wheel 79 (see Fig.

l I' vided, such, for exam le, as the familiar form of carrying device siown, consisting of an idler pinion 91 mounted loosely on the shaft 9) and which is periodically engaged and rotated by a pair of diametrically mounted loosely on the opposite teeth on the sixth register 'wheel 90, and as the latter moves from 9 to 0 and when so rotated, in turn rotates the'seventh v I or last register wheel 90 one numeral through 10 a inion fast to said register wheel and with ch said pinion 91 meshes. Referring now to Fi s. 2, 3and 17, the printing mechanism wil be described. This consists of a series of printing wheels 95, end of the shaft projecting beyond partition E, a platen 100 coacting therewith to cause the ty e thereon to print upon a strip or tape 99 (t e matter printed on which is to be readirom the front 2.0 of the machine), and an inking roller 114 for 25 five banks of keys representing amounts and banks,

' rotated by gear gear teeth with inking the type on the rinting'wheels; all these parts being located) in the casing l at the right hand side of the machine. There are six printing wheels 95, one for each of the the remaining one for the bank of system keys bearing letters and abbreviations. They are all alike i-n construction and are all o erated by the gears 24: of their respective ey the connections through which they are so loperated consisting of the shafts 64 24, and pinions 96 fast to the right hand ends of said shafts (viewed from the front of the machine) and meshing with which their respective rintmg wheels are rovided for a portion o their erip'heries. he pinion 96 at the'extreme eft of the rear elevation, Fig. 3, actuates the unitsprinting Wheel 95, .the next one actu.-

, 40 ates the tens printing wheel, and so on, while to indicating position,

i the one at the eXtreme right of Fig. 3 actuates the system printing wheel 95. v

Each typewheel 95 is provided with ten type and, as theindicators 62 68 are rotated said typewheels lwill be correspondingly rotated to bring to the printing pointthe type corresponding to the indications made by the indicator Wheels, re-

' taining this position until the indicator wheels are returned to normal or zero position, when J 100 i's carried in the end of an they are also returned to normal position by y pinions 96. The platen4 the shaft-64 through arm 97 loosely mounted enea stud 98 projecting from the 'partition E, said arm having connected with it on the opposite side a spring 106, the other end of which is conl tlie printing w ee of said stud, one end of nected with the partition E and the function of. which is to ro l vtheVY platen 100 against and paper at the proper time. This spring106 is put rock thearni 97 and cause i against the paper and type by a cam 104 fast l to shat'2 and which azi-lever 3 and said shaft 108 into engagement withtlie projection 109 gong lever 59.- t

under tesion to'- platen to strike- 2 are rocked rearwardly, :as heretofore de- 65 scribed, engages a projection 105 through which it depresses the arm 97 to the position lshown in Fig. 17, and puts spring 106 under tension. This rearward movement ofv lever 3 and also its forward or return movement to the position shown in the drawings, it will be remembered, takesplace between sales, and, according to the usual practice, just before what may be termed the next sale is to be indicated and -registered, as previously eX- plained. The arm 97 is retained in this depressed position, with the spring 106 under tension, by a spring-pressed pawl 107, the upper end of which engages aprojection 109 on the arm 97. This pawl is mounted on the end of the drawer-lever shaft 108, previously referred to, with a limited amount of looseness or play circuinferentially of said shaft (as shown in Fig. 17) permitting movement of said pawl, by its spring, relatively to shaft on' arrn97. When, as'heretofore described, the drawer-lever 57 is rocked by cam 55 on shaft" S5 to withdraw holt 56 from the drawer B, saiddraWer-lever 57 will rock shaft 108 with which it is rigidly connected, and, engaging the pawl 107, will move the latter, against the pull of its spring, out of engagement with. projection 109. The spring 106 will then propel the arm 97 upwardly and causethe platen 100 carried thereby to strike against the paper and the type on the printing wheel, and thus effect the printing. As the arm 97 thus flies upward, a spring 111v thereon will strike against a stop 112 on-` the partition, irst stoppin the upward movementco said arm and t ien moving it downwardly slightly so as to withdraw its platen n 100 from the type, in which position it will remain until, just before the next sale, the lever 3 is moved rearwardly and said arm 97 moved downwardly thereby, as just described. l

, The shaft 35 is 'geared to a governor 60 which retards its movement when propelled by its spring 49 so that the shutter lever 93 will be released by segmental gear 33, the

withdrawn from the? drawer after the movement of the indicator wheels 62, 68, to indicating -position and of the type wheels 95 to printing-position has been completed; the withdrawal of pawl107 from engagement with rejection v109 on arm 97 following the Withriiawal of drawer '.bolt 56, so that the spring 106 may propel said arm 97 upward for rinting.

A e inking roller 114 is, as will be observed on reference to Fig. 2, of a width sufucient tol ink the type of the several rinting wheels 95. It is made -iip of a metal) sleeve, revolving freely on a s indle-iedj to an' arm 113, and a-pluralityl o mkingrolls revolving j d and drawer-,bolt 56
