General construction.

1 represents the main frame of'the machine which may be of any suitable construction so as to support the working parts of the machine. Y

2, Figs. 2, 7, and 9 represent a number of main dials which register the total of the numbers which are added together. These dials consist preferably of cup-shaped wheels which are nu bered on their peri hcry and are mounted. in their pro er or or on a transverse dial shaft 3, \vhic is journaled in hearings on the main frame, the dials being so arranged that the dial re iresenting the lowest number is arrange on the right hand end of the series and the dials representing the successively'lhigher numbers being arranged successively in their order toward the"left from the dial representing the lowest number. The lowest or right hand dial preferably divided on its periphery into eighths so as to'indicate fractions of a cent in eighths, and the remaining dials are graduated on their pe riphery according to the decimal system into tenths. As shown in the drawings ten total dials are shown and extend from fractions of a cent to tens of millions, but if'desired. additional dials may be added to the right and to the left of the series, if it is desired to register smaller divisions of a cent or more than tens of millions. Each of the main total dials 2 is provided onits left hand side with a gear inion 4, which is rigidly connected therewith, as shown in Figs. 2 7, and 9. The pinion of the fraction wheel has eight teeth while the pinions of the remaining dials are each provided with ten teeth. 5 represents the main registering gear segments, one of which is provided for each of the dials 2 and is adapted to engage with the pinion thereof, for operating the respective dial. Each of these gear seg ments is arranged in rear of its companion gear pinion and is provided at its lower end with a rearwardly projecting arm 6 which [13 pix otrd loosel on a transverse supporting rod 7. This rod is mounted with its ends on the upper ends of two rock arms 8 which turn loosely with their lower ends on a transverse rock-shaft 9. The rock-arms 8 are connected by a transverse bar 10 which compels the two arms to move back and forth together. In

the normal position of the gear segments when themachine is at rest these segmentsare retracted rearwardly out of engagement with the dial pinions of therdia ls and the segments are elevated so thatth ir lowermost"teethare opposite the spaces; etweenthe adjacent teeth of the dial p nions, these spaces bein inline with the pivots ,of, the pinions and t e gear segments.

This camis mounted on the upper portion ofa vertically. swinging rocking frame 15 whichis' arranged on the right hand side of the; machine. This cam is provided at its front end with an incline or cam face 16 and at its rear end with a concentric face 17. When the cam is in its rearinost or retracted positiontits incline stands in rear of a roller orprojection 18 on the rear end of the shifting nrn1,13,;as shown in Figs. 2, 7, 9 and 17. Upon swinging the rocking frame 15, so that Ithe cam 14 moves forwardly, the inclinel'off the latter engages underneath the roller18 and raises the arm 13, thereby movinglthe arms 8 forwardly." The throw of th eiincline 16 is just sufficient to engnge'the teeth of the gear segments with the dial pinions.- When the roller 18 has been raised to the top of the incline, the concentric portion of the cam engages with the rollerduring theeontinued forward movement of the cam and the latter does not shift the gear seginents any farther forward.

the rear end of the concentric face 11.0fthe cam passes forwardly from underneath :the roller 18, the constant pull of the springs 11 causes the rock-arm 13 to be depressed and the rock-arms 8 to be moved rearward, thereby disengaging the gear segments from the dial pinions. Upon now moving the cam 14 backwardly together with the rocking frame 15. this cam does not affect the arm 13 and the parts con-. necteditherewith, but is affected by said arm at the lastportion of the backward movement of the cam, at which time the back or lower side of incline 16 en ages with the roller 18 which lifts saidinc inc and at the end of. the backward movement of the earn, the latter "clears .said roller and drops behind the same,- as shown in Fig. 2, preparatory-toagain raising theroller 1 8 and con-. necting partse', dur1ng,. ,the next; forward movement of thotam- 4- Z y;

Upon depressing the transverse bar 25, the lifting bar ,22 is moved downwardly and the gear segments resting thereon are permitted to. move downwardly with the bar untilathe segments are arrested a V r i Each 'ofithe gea-iysegments is yieldingly held in contact with the lifting bar 22 by a spring27 which connects the arm of the segment with the transverse bar 25. If the downward movement of the gear segment is arrested while the shifting arms 24 continue to move downwardly, the lifting bar 22 is moved away from the underside of the arm of the gear segment and the spring 27 is strained. The transverse bar 25 is arranged at one end in a segmental notch 28 formed in the front part of the rocking frame 15, shown in Figs. 2, 7, 9 and 17 and its opposite end is arranged in a similar segmental notch 28, formed in a rocking frame 29 which is secured to the operating shaft on the left-hand side of the machine. The rocking frames 15 and 29 together with the operating shaft constitute the main or universal operating frame ofthe machine.

When the machine is at rest, as shownin- Fig. 2, the transverse bar engages with the front side of the'notches 28 in the rockingframes 15 and 29. Upon turning the rocking shaft 'QOfOIWflI'CllYfbY means of its handle 21 in-the direction of thearrow, Fig.

2, the rocking frames are moved forwardly duringthe fir'st' part of the movement inclependent of'the transverse bar 25.

been engaged with the dial pinions, the conwardly"and to continue their downward movement until they are arrested. During the"downward movement of the gear seg- 1nents,wliile theyare in engagement with the dial pinions. the latter and the dials connected therewith are turned in the direction of the arrow, Fig. 7, until the down:

ward movement of the segments is arrested.

The extent which each dial is turned depends upon the position in which the downward'movement of its operating segment is arrested. After the segments have been arrested in their downward movement, they r'emain'in this position while the rockingframes complete their forward movement. At the end of the forward movement of the rocking frames. the roller 18 of the rock arm 13 drops off from the rear end of the con centric part of the cam 14, thereby allowing the springs 11 to pull the rear segments rearwardly out of engagement from the dial pinions. I

Upon now turning the rock-shaft 20 backwardly by means of the handle 21, the rocking frames are moved backwardly until the front ends of the notches engage with bar 25. When the latter is so engaged it is moved backwardlv with the rocking frames to the end of their rearward movement which causes the transverse bar 25 to lift the lifting bar 22 and the gear segments which have been depressed, into their highest or normal position. During this upward movement of the depressed gear segments they are out of engagement with the dial pinions, so that the dials are not turned backwardly with the segments, but remain in their shifted position.

After the gear segments have '30 represents a 'niunhei -of 'elbow'-shb.ped controlling arms whichform part ofthe devices whereby the downward movement of the registering gear-"segments is controlled.- One of these arm's-is arranged along the left-hand side of eachgrear segment and con sists ot an'uprightfront Dartfifid ahori-"l zontal lower part which "extends -ral'wardly from the lower end 0fthe"upright part, thereby leavi-ng-a-clear space in rear of the upright part ofthe controllinglever as represented in" 1, 2, 7,; 9;- and 16: The rearend of the lower partofeachcontroL ling arm is mounted looselyon a-transverse supporting bar '31-, while the upper end of its front orupright part is loosely connected with the upper portionof. its companion gear segment; This loose-connection permits the controlling arm-and the, gear ment-to swing "freely about'their individual axes, which are arranged paiallel but' out of line, and also peri'nits the gearsegment to move forward andjbaclrward into and oiit'of engagement with its companion dial pinion, In the uppermost position oftheicontrolling arms the sameibear with"their upper ends against a transverse stop bar 32, as-shown in Fig. 2, which limits the upward movement of these arms. Each controlling arm is provided on the rear part of its upper end with a locking lug 33, and on the front part of its upper end with a stop lug34,' both of which lugs project toward the left and are preferably stamped out of one piece with the controlling arm.

The operation of the re istering' devices is controlled 'bya number 0' elbow-shaped key levers which are arranged side by-side and pivoted to a transverse supporting rod 35. Each key lever is provided with a lower actuating arm 36 which projects forwardly and an upper stop arm 37 which projects upwardly along the left hand side of one of the controlling arms and gear segments, as

represented in Figs. 2, 7 and 16. Each of these key-levers is provided on the rear side of its stop arm with a lockin shoulder 38 which is adapted to engage wit the locking lug 33 of the controllin arm when the latter is elevated into its ke v-lever is in its'fully retracted position, as shown in Fig. 2. When the parts are in this pos tion, the key lever holds the controlling arm against downward movement and the latter holds the gear segment against downward movement. Tf the gear segment while so held against downward movement is moved forward into engagement 'with the adjacent dial pin-ion, and the rocking frames are turned forwardly for depressing the gear segment, the spring 27 of this segment will be strained without, however, shifting the segment. At the end of this forward movement of the rocking segments, the roller 18 of the rock arm 13 drops ofi' highest position and the i.

from the rear end of the cam 14, the gear segment is moved rearwardly out of engagement from the dial pinion and then the rockin frames more backwardly without having shifted the dial. The upper arm of each key lever is provided on its front side with a vertical series of different stop shoulders 39, which are arranged step fashion and extend from the upper end of this arm downwardly and forwardly thereon or in other words the stop shoulders are arranged radially out of line with one another and different distances from the pivot ofthe key lever. These stop shoulders of the key lever are adapted to he moved'forwardly into the path of the stop lug 34 on' the controlling arm. The stop shoulders are arranged different distances from the stop lug 34 of the controllin arm. sotha't by moving different stop shoul ers of the key lever into the path of the stop lug of the controller arm, the latter and the gear segment connected therewith may be arrested at different points in their downward movement. The uppermost stop shoulder of the key lever is most remote from the stop lug of the controlling 'arm and therefore requires the greatest forward movement of the key lever, in order to bring .this stop shoulder into the path of this stop lug.

The stop shoulders of the key lever are so arranged that the distance from the stop shoulders to the path of the stop lug gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. The relative position of the different stop shoulders of the key lever is such that when its locking shoulder 38 remains in engage ment with the locking lug 33 and the gear segment is simply moved into and out of engagement with its dial pinion, the latter remains at zero. if the same has not been previously moved. But when the key lever has been moved forwardly, so as to disengage its locking shoulder from the locking lug and moves one of its stop shoulders into the path of the stop lug of the controlling arm, the latter arm and gear segment connected therewith willfbe moved downwardly 'up'on moving the rocking frames forwardly, until the stop lug of the controlling arm's'trikes the respective stop shoulder of the key lever which stands in its path, as represented in Fig. 7. whereby the gear segment. while turning in engagement with the adjacent dial gear pinion turns the same forward. By turning the kev lever forward more or less and moving one or the other of its stop shoulders into the path of the stop lug34: of the controlling arm, the d stance which this arm descends can be varied, thereby varying the number of spaces which its gear segment turns the adjacent dial;

Maz'n number key mechanism. 40 represents the main keys whereby the key levers of the main registeringnandyrcording mechanism are operated, and which a re guided with their depending stemsin the top 41 and bottom 12 of the keyboard. 1' As shown in the drawings, nine longitudinal cclumnsof these keys arearranged transrersely side by side 'l he first bolumng-on the right hand side of themachinecontains seven keys and represents fractions ;ofone eighth of a cent, the next columntoward-the left contains ninekeys and representscents and the remainingeolumnsioflkeys' toward the left each contains 'nine keys and :repre- 'sents progressively higher orders of numbers according to the decimal system, so that the registering keys in the last or left hand colf umn represent hundreds of thousands of dollars. t f ,7

The lowest numbers of the, several col runs of keys are arranged transversely in; arow on the rear part of the key-board and the corresponding higlier numbers of the several columns are arranged likewiseii'n' transverse rows and progressively in their ordertoward the front end ofthe-key-board. li (4-; [ma Each of the registering keysiisyieldingly held in an elevated position by a. springs?) surrounding the stem of the key andaconneeted at its upper end to the key an'dbear ing with its lower end againstthe bottom of the key-board. The upward movement of each key is'limited by a shoulder44; formed on the upper part of its stem and enga 'ng with the undersideof the top of the i 63 board. I i Ll ly' The downward movement of al offthe keys is substantially the same, but theyarraugement of each column of keysllen hwise ofthelower actuatingarm ofeach ey lever causes the keystobear against their lever at different distances from its ivot so that by depressing different keys -t e same distancmthe key lever will beturnedldifferent distances. The keys having the lowest numbers bear against their respective key levers nearest the pivot and consequently-the levers are thereby thrown the greatest dis tance, and the uppermost stop shouldersare shifted into the path of the stop-lug 34 of the respective controlling "arms. The throw of each key lever upon depressing any one of its keys is so adjusted, that the; proper stop shoulder on. its upper arm is moved into the path of the stop lug 34 of the controlling arm and the downward movement of-the respective gear segment is arrested after having turned the adjacent dial gear pinion a number of spaces correspondingto the number of thekey which is depressed; T

loose connection for segments;

The loose connection between eachcontrollingrarm and its gear segment, heretofore referred to, is shown inits simplest form in the connection between the control-v ling.aunt:andi-thev .segment, which are controlled; by the initial or lowestcolumn of 'registel 'ing. keys, As shown in' Figs. 1

and 22,- thesloosr connection between the "arnrn iAsithecontrollinigi; arm: and segment rise and fall', the guide gsof the segment slidebackand forth on the guide faces of the arnn- The guide fares are so constructed that the back and forth movement of theisegment. onthe arm is radially with reference to the dial pinion in all positions of-the segment. By so forming the guide faces of the arm, the gear segment can be engaged with and: disengaged from the dial pinion in all positions of the se ment with out disturhi ng the position of the dial pinion. The construction of the loose connections betweenthe controlling arms and gear segnmnts of all. of the higher registering devices above the fractional registering device are combined with carrying devices,'wherebyeach registering dial, upon making one complete turn causes the next higher dial to be turned forward onespace, thereby carrying npa number from one column to the next higher column. The loose connections the controlling anus and the segments and the carrying mechanism of the higher registeringdevices are constructed as follows shown in Figs. 1, 2, 7 and 22, each controlling arm is provided at its upper end with upper and lower guide faces 47 and 4.8 and"; its lower guide face is engaged by a lower guide lugl6 on theadjacent gear segment, the same as in the coupling between the controlling arm and segment of the initial registering device. The gear segmeager-the higher registering devices are carh providedwith an upper guide lug 49 which is adapted at times to bear against the upner'guide face 47 of thecompanion controlling arm in substantially the same manner in which the upper guide lug ofthe fractional gear segment hears ag nitsyompaniOna -m the only difference being that' 'the upper guide lugs 4:9 of the higher gear segments are held out of engagement andysenarated, by a space from the upper guideface, of the companion arm when no number is carried from a lower to a higher registering device. The upper guide 111;! 49 is held, in this, elevated position above the adjacent guide by a rocking latch 50 which is arranged in a notch in the rear of the gearisegment and which normally projects toward the left and engasres with the upper guide face 417 of the adjalever and this .arm-in'tnrn controls the extent of the downward movement of the gen-r segment. When, however, the locking finger 50 is withdrawn out of engagement from the upper guide-Iface 4770f the arm,- the companion gear segment is capable of moving downward independent of the arm until the upper guide 'lug 49 engages 'with' the upper guide faceofthe arm.'' The extent of this independentmovementof the gear segment witlr referenceto its companion arm is equal to one tooth or space-of; the Segmerit, so that bythis moansrthejgear segment is-enahled tofiurn the dial pinion one space more than-"the position of the key lever permits the same to move; i

The withdrawal of the locking latch of each higher registering; device is controlled by the nxt lower registering device and the withdrawal of each latch is effected when the next lower registering device hasmade one complete turn and arrived at zero; Each of the locking latches is pivoted on the right hand side of its adjacent gear segment, so as to turn transversely with reference tothe latter. The latch is turned toward the left into its operative position by a spring 51. the movement in this direction being limited by a shoulder 52 arranged on the latch and bearing against the right hand side of the. gear segment. 53 is an upright trip plate connected with the'lower 'end of each latch and arranged normally at right angles or nearly so to the adjacent gear segment, when the latch is in its operating position. 54 represents a' number of upright trip arms, eaclrof which is controlled by a lower registering device'and which turns the locking latch of the next higher registering device into an inoperative'position. This arm is mounted loose]; with its lower endon the supporting bar 35 andis provided at its upper end with a rearwardly and forwardly projecting hook and in front and below said hook with a bend forming a bearing finger 56. 57 represents trip cams arranged on the left-hand side of each registering dial pinion and connected with thc adjacent pinion and dial, but separated from the pinion by an intervening space orqroove. The face of each of these cams may begin at its lowermost point near the axis thereof'and then exis turned in the direction of tend outwardly in a spiral line terminating with its highest point in line with its lowermost point with which it connects abruptly. The trip cam of the fractional registering device has its face divided into eight parts, each part of which except the'first is arranged one-eighth of a space farther from the center of the cam than the preceding part, while the trip came of the higher registering devices each has its face divided into ten parts, each part except the first being arranged one tenth of a space farther from the axis of the cam than the preceding part. Each of the trip arms 54 extends upwardly along the right-hand side of the trip cam of a lower registering device and its shoulder. 56 engages with the face of this cam, while the hook at its upper end extends toward the left and is adapted to engage with the trip plate 53 of the next higher registering mechanism. In the initial position of each trip arm, its shoulder 56 engages with the lowest partof its trip cam. As the trip cam the arrow, Fig. 2, atthe same time that its dial and gear pinion are moved forwardly by the adjacent gear segment during the adding operation, the trip arm is moved backwardly by the graduall rising face of the trip earn. During this backward movement of the trip arm, its hook engag s with the trip plate 53 of the next higher registering device and is de-' flected toward the right thereby, the hook being sufiiciently elastic for this purpose. After the hook has passed in rear of said trip plate, the hook owing to its resilience springs back to its normal position, so as to stand behind said trip plate. When. the shoulder of the trip arm reaches the highest part of the face on the trip cam the trip arm h as been shifted to its rearinost position. Upon now turning this cam forwardly another space together with its companion dial and pinion, the highest part.- of the cam. is carried from underneath the shoulder of the trip arm and. the latter is moved forwardly over the abrupt face of the cam until its shoulder 56 again engages with the lowest part of the cam face. During this movement of the trip arm, its hook strikes the rear side of the trip plate 53 of the next higher registQI'lDQ mechanism and turns the same. forwardly, thereby disengaging the locking latch froin the adjacent controlling arm and permitting the gear segment carrying the trip plate to move forward one space. The forward movement of the trip arm is effected when the. dial with which its trip cam is connected has made one complete rotation and again stands at zero, whereby the addition, represented. by this complete rotation is carried to the next higher registering device. The forward movement of the trip arm is effected quickly by a spring 58, which connects with a stationary cross bar 59 arranged in front of the trip arms. The trip plate 53 of eachiregistering device is soarranged and is. of such length that the hook of the next lower 'tri arm. canengage with the rear side of the pliite, for disengaging its latch in any position of the gear segment carrying the plate and in order to accomplish the engagement it is obvious that cams 57 should be constructed so as to give arms 56 the proper throw; 'If a gear segment is locked in ItS highest position by reasonof none of its chn i 'anionlieysh aii'ingbeen depressed, the withdrawal of its latch froni'the eontrollin arm simply permits the gear segment to crop one space and turn- .1tscompanion dial pinion forward one space; while in engagement therewith, the movementof this dial representing one numberica'rried' up from the next lower; dial. an (we of the I keys of the key levers has been' d epifesseilso as to release thegaltsegment and erinit'thb same to move downwardly to "Le et-ting an addition, a'nd ignori g; this age the atria: e r r i ter n restraints .f-e inip a ,.s s'td?rqr r i ierhfy fig p of a 'l f m h eifiler frsil tefi s mechanism, the latch fgf the higher. registerin g device will be withdrawn the same is effecting its "addition, thereby cansih'gthe segment to descend and dial one space in addition to the space'corresponding to the depression of its res ective key. j

When the locking late has been withdrawn sons to permit a gear segment to move downwardly one space farther than its controlling arm, the latch remains in this position during the subsequent upward movement .of the anti andthe segment until the upward movement of the armlis. arrested by striking the stop her 32 mu-11s gear segment continues its upward movement independent of the. arm the extent of one s ace. The gear segment has now reached its highest position and itslat'ch isagain swung automatically by its spring over the controlling arm." The controlling arm and gear segment now remain in this relative. position until another number is to be carried up from the next lower registering device. When-the controlling arm has been retracted to its highest pos tion the adjacent keyv lever is moved into its normal retracted position. so that its locking shoulder 38 engages with the locking lug-33 of the controlling arm and locks the latter against downward movement. The return movement of each key lever is preferably efi'ectedhy a spring 60 which connects the upper arm of the key lever with the transverse shaft 9,as shown in Figs. 9 and 7 or withsoine other convenient part of the machine.

After the rocking frames 15 andz29 have been turned forwardly'sufliciently to eiigage the several feeling fingers ,of the feeling levers with=their respective trip cams, the rcarends of the segmental notches in the rocking frames engage with tho cross bar 25 and depress the same, thereby moving the lifting bar downwardly and at the same time pulling down the springs {27. This downward pull on these springs causes each spring to pull its respective gear segment down as far as pos sible, and after the downward movement of the segment has been arrested the continued downward movementof the cross bar together with the rocking frames simply stretches these springs until this bar reaches ion trip cam wh tion, each depressed its dial backward the fment subsequently ga lthe end of its downward movement.

For the purpose of recording the numbers which are added together by the above described mechanism a recording mechanism is provided which is constructed as follows 140 represents a printing roller or platen which is arranged transversely in the upper. rear part. ofthe machine and under the lower side of which the sheet or other article is placed which receives the record. 141 represents a numberoftype segments which are arranged transversely side by side below the platen and which are pivoted at their front ends'to the supporting bar 31 upon which-the-rear ends of the controlling arms 30 arepivoted. Each of'these'type' segments is provided at .its' rear end with a segmental row of type carriers- 142, which are capable of moving radially back and forth 'on the -type segment; at}; 1.. .51. I :1 Each i of' the typerarriers is" provided at 'it srearen'd with-a type and is guided upon the ty e-se ment by means of screws or rivets 143' secured "to the type carrier and arranged-in radial slots 144 formed in the type segn ie nt," as shown in -Figs;12, 3 and 111 Eachof the type carriers isheld in its inward ormetracted position bymeans of an S-shaped" spring 14:5,which is arranged between tliecarrier and the type" segment andissecured with one end to the carrier andwithits other end to the type segment. 'Upon raising or lowering'the type segment anyone of 1ts type can be brought to the :prlnting'f point or line; and upon striking the back-or inner end of the type carrier,

whensthe same is inline with the printin'g -point the type carrier will be driven ou'twardly and itstype will produce an impression on the sheet supported by the platen. After the carrier has received the blow for driving the same "against the platen, the carrier is again quickly retracted to its innermost poslt on by means of its n f Each of-the type segments is connected {with onset the controlling arms, so that upon depressing a controlling arm and the registering gear segment connected there- 'with, the companion type segment will be raised and present one of its type to the printing point. g

* For convenience in operatingthe machine, the keys are separated a considerable distance on the key-board and in order to produce a compact record, the printing segments are arranged closer together than the keys and the registering mechanism. In order topermit of this arrangement. each type segment and its corresponding controlling arm are connected by a connecting arm 146, as represented in Figs. 1, 2 and 16. the con necting arms of the central controlling arms and type segments are comparatively straight, but the connecting arms of the outer type segments and control] in g arms are arranged obliquely, the degree of this obliquity gradually increasing from the central type segments and controlling arms in opposite directions toward the outer type segments and controlling arms, as repreof the outer controlling arms are arranged 'sively downwardly 'fromthe zero type. '-:Whenithe registering gear se out is iniits highest position it presents ltS'ZGIO tooth to the dial pinion,'and the type segment which at this time is in its lowest position presents-its zero type to the printing point; Upon depressing a gearseginentso as topresent one of its higher'teet to the dial pinion, its

companion type segment is raised proportionallyand presents a corresponding higher numbered type tothe printing poin't.-'

147 represents a number of "hammers whereby. the type carriers "are struck -for driving the type against the'j platen; l ()ne of these hammers is arranged adj accnt to each type segment and is provided with a head which is arranged in'frontof. the series of types and in line with the printing point of the platen. Upon shifting the type segment so as to bring oneor another of its type carriers to the printing line and then operating the hammer, the latterdeliveis a blow against the inner end of the particular carrier which is at the printing point and produces an impression of its type on'the platen. The several hammers are pivoted on the transverse rod 12, arranged in rear of the segments; and each of the hammers is yieldingly held in its forward position by a spring 148 connected at its lower end to a crossbar 149 and at its upper end to a depending arm 150 on the hammer.

151 represents a verticallymovable trip bar or rod which is arranged transversely below the hammers and whereby the latter are operated. This-barf is supported at'its ends upon the rear ends of rock arms 152 which turn loosely with their front ends on the rod 31 supporting the controlling arms.

153 represents a number of hammcr or trip pawls, whereby the hammers are retrag-ted preparatory to delivering a blow against the type carriers which are at the printing point. One of these pawls is arranged adjacent to each hammer and piroted loosely at its lower end to the trip bar 151, and its upper end is provided on its rear side with a downwardly facing hook or shoulder 154, and above said shoulder with a trip face 155, as shown in Figs. 3 and 6. Each of the hammers is provided in front of its pivot adjacent to the upper type segments and end of hhevltammer pawlwithaa lower trip lug. or shoulder 156: and anupper trip lug or shoulder 157*. When-the parts are at rest, the hammer pawl 153 is' raised into its high est position: and the hammer is in itsinormal position with its lower trip lug 156 below and in! rear of thehook. of the hammer pawl and with its upper shoulder 157 in rear of the trip face of the hammer pawl, as represented in Figs. 2 and 3.

U n shifting the hammer awl rearwar ly', while theparts arein this position, so that its hook overhangs-the lower shoul der 156 ofthe hammenand then pullin the hammer pawldownwardly, the hook 0 the hammer pawl engages with the lower shoulder of the hammer and turns the same so that its head is retractedfrom the type carrier at the: printing, line;- Asthe ham mer moves downwardly with the hammer pawl, the upper shoulder of thehammer comes into engagement with the trip face of p the hammer pawl and during the continued downwardmovementof the hammer and its pawlgthis upper shoulder gradually crowds the hammetr pawl forwardly with reference to the-hammer by reason of theha'mmer and its.- awl swinging; on diflerent centers. During. the last portion of the downward movement of. the trip bar 151 and the hammer pawl mounted thereon, the pawl is crowded forwardly by the upper shoulder 1-57 of the hammer to such an extent that its hook is disengaged from the lower shoulder 156 of the hammer, thereby liberating the latter and permitting its spring 148 to throw the same quickly and deliver a blow against the type carrier at the printing line. The trip bar. 151 now rises and carries the hammer pawl into its highest position, preparatory to againengaging the hammer for depressing the same.

158 represents a number of upright shifting arms whereby the hammer pawls are moved rearwardly, so that their hooks engage with the lower shoulders of the hammers. One of these arms is arranged adjacent; to each hammer pawl, as shown in Figs- 3 and 6 and is pivoted at its lower end on the trip bar 151, and its upper end is provided with a roller or PIOJBCtiOIl 159 which bears against a hammer cam 160 on the lower partof the adjacent type segment, as shown in Figs. 3, 7 and 16. This hammer cam is provided at its upper end with a receding or low portion, an inclined portion arranged below the low portion, and a concentric or high portion arranged below the inclined portion. Each shifting arm 158 is moved forwardly and its. roller is yieldingly held in engagement with the adjacent hammer cam by a spring 161 connecting said am with a cross bar 162- se cured to the-roekarms 152, as represented in Figs. 7 andS: The backward movement oat each hammer pawl; with reference to its companion. shifting arm, is limited by means of a stop 163 secured to the upper portion at the hammer awl and; engaging with the front side of t a shifting arm, as represented in Figs. 3-, 5 and-14.

Each hammer pawl. is yieldingly held in its rearmost. osition: with reference to its shitting arm y means of a; C-shaped s ring 164. secured withits ends, respective] to the hammer! pawl and its shiftin' arm, as shown in Figs. 2, 3 and 14. Inlie lowermost position at atype segmentthe receding art of its cam iii-presented to: the roller of t e shifting arm 1-58, which permits the hammer pawl to be retracted into its f0nemost position, as represented im ig. 2. Upon depressing the trip bar 151 when the parts are in this" position, the roller 159 is not engaged soon enough by the incline of the cam 160 to engage the hook or the hammer pawl with t e lower shoulder of the hammer, before. the book has passed below this shoulder; but instead thetrip face-of the hammer paw-l slides idly against the shoulder 156-without retracting the hammer, whereby no impression of the rticular t .pe at the printing line isprodiibed. If t e type segment is' raised, so as to present one of its lower typesto the printing point or line, the incline of its cam, during. the first part of the upward movement of the segment moves the shifting arm 158M1 wardly together with thehammer pawl, yieldin 1y connected therewith, so that the book 0 the hammer awl stands over the lower shoulder 156 o the hammer. Upon now depressing the pawl 153' the hammer will be retracted and released near the end of the downward movement of the pawl and will bequickly swung up by the spring 148, thereby delivering a blow against the type at the printing pointand producing an impression thereof.

The incline 1601 oi the. type'segment cam is so constructed that it throws the hammer pawl backwardly into an operative position when the segment is raisedone digit space, and during the continued upward movement of the segment, the hammer pawl is held in this operative position by the high concentric part of the segment cam. By thus constructing the t a segment cam, its companion hammer paw is not shifted when the segment is not raised and its zero type remains at the printing line, but the hammere pawl is shifted into an-operative position for producing an impression, if the type segment is raised one or more digit spaces and presents any one ofits digits higher than zero to the printing line.

Automatic printing of zero.

165 represents a number of transfer or coupling fingers which enable the ciphers in a number to. ,be printed automatically. One of these transfer fingers is secured to each of the shifting arms 158, as represented in F igs. 3, 7 and 14, andextends laterally toward the right therefrom into engagement with the shifting arm of the next lower hammer pawl, as represented in Fig. 19. If any one of 'the printing se ments remains in its lowest position, so t at its cipher remains at the printing line and the vnexthhigher printing segment has been :raised forqprmting a higher number .or

digit, the transfer finger of the higher hammer shifting arm 158 while being moved rearwardly by the cam of its companion printin segment, is caused to engage with the shi ing arm 158 of the next lower hammer pawl and shift the latter backwardly, so that its hook is carried backwardly over the lower shoulder of the companion hammer. Upon now depressing the trip bar 151, the higher hammer pawl 153 is coupled with its hammer and the next lower hammerpawl is also coupled with its hammer, whereby an impression of the cipher or zero type on the lower segment is produced on the platen at the same time that the next hi her number is printed on the platen.

f two ciphers occur in succession in the body of a number, the shifting arm to the left of the highest order printing segment to be operated for printing a zero sets the hammer. mechanism of said highest zeroprinting segment by means of the transfer nger of said shifting arm and the shifting arm of said highest zero-printing segment in turn by means of its transfer finger sets the hammer mechanism of the printing segment of next lower order, etc. This 0 eration of producin an impression 0 the cipher type is e ected automatically and renders it possible to print any number of ciphers in succession in the body of a number because the hammer operating mechanism of each segment which remains standing with its upper type at the printing line is controlled by the hammer operating mechanism of a higher type segment and in turn controls the hammer operating mechanism of the next lower type segment, if the next lower segment presents a cipher to the printing line.

Only the ciphers below the highest digit in the number to be recorded are thus printed automatically because the printing of a digit depends upon the upward movement of a printing segment, thereby avoiding the printing of ciphers ahead of the highest digit in the number to be recorded. The hammer shifting device of the segment which prints the numbers representing units of cents is preferably, not provided with a transfer finger to operate on the hammer Shifting device of the segment which prints fracti ns i a c nt, cau it is P p that the space to the right of the lowest integer shall remain blank when no fraction is recorded therein.

The carrying bar 151 is raised by one or more springs 166 which connectthisbar with the transverse rod 12, as shown in Fig. 8, and the upward movement of the bar 161 is arrested when the hammer o ,erating ,pawls reach their highest position a transverse bar167 which is engaged bythe rear ends of the rock arms 152. 168 represents a coupling hook, whereby the hammer'trip devices are depressed. This hook is pivoted with its upper end to the trip bar 151 and its lower engaging end is provided with a notch having upper andlower shoulders.

In the lowered positiomof this hook its notch engages with a cross bar which the rock arms 24. 3 In the rearmostposition of the rocking-frames, the front ends of their notches 28 bear against the front side of the bar 25 to which the gear segments areyieldingly connected and the crossbar 169 bears against the rear or upper shoulder of the notch of the hook 168, as represented inFig.2.

Upon swinging the rocking frames'torward, the incline of the cam, 14 first raises the rock arm 13 and shifts the gearsegments into engagement with the dial pinions, and after the segments have been so shifted, the rear shoulders of the notches 28 in the rocking frames engagewith the crossbar 25, so that thereafter this bar is carried downwardly with the rocking, frames and the,

gear segments are depressed. During this downward movement of the bar 25 with the rocking frames, the companion bar 169 moves down idly in the notch-of the hook 168 until this bar engages with the lower or,

with are moved downwardly with the rock-,

ing frames until these frames reach the end of their downward movement. During the last portion of-the downward movement of the rocking frames the hammer pawlsare disengaged, as before described, from the retracted hammers, whereby the latter are released and strike the type carriers which are at the printing line. By this means, the blow of the hammers is delivered after the registering of the numbers has been effected on the dials and the type segments have been shifted into their proper position for recordin the respective number. a
