Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed August 14, 1905. Serial No. 274,099.

To all whom it may concern:

Be it known that I, THOMAS Gammon, a citizen of the United States residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in (lash-Registors, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers more particularly to that type in which manipulative means are lirst adjusted according to the naturc of the transaction to he entered upon the machine and the completionofthe operation of the machine is effected by means of the subsequent actuation of a driving such as a crank handle or operating lever, and it is among the various objects to provide certain improvements in connection with the settinp and operation of certain elements differentially to secure the customary differential extents of movements ordinarily utilized in machines of this than actor for actuating accounting devices or indicating devices, and it is also one of the objects to provide a novel form of driving,

mechanism for the machine.

W'ith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 represents a front elevation of the cash register to which these improvements are a )plied. Fig. 2 represents a cross section 0. the machine on the line 2-2 of Fig. 1 lookin c in the direction of the arrow crossing said line, certain of the operating parts of the machine being hidden by an intervcning supporting frame of the machine. Fig. 3 represents a vertical cross section of the machine approximately on the line 3-3 of. Fig. 1 looking in the direction of the arrow crossing said line, this section being just inside the above mentioned intervening supporting frame. Fig. 4 represents a vertical section on the line 4-4 of Fig. 1, being adjacent to the bank Fig. 4" represents a de ail de vice view of certain companion gear wheels and an idle pinion for coupling the same togctluar in 'onncction with the. counter actuating mechanism. Fig. 5 represents a vertical section of the machine just; inside the lcft hand side frame of the mach'uicl Figs. :1 and 5" rcpwscnt detail views of mcchanism connector] with the restoring frame. Fig. 6 represents a modified form of manipulative device. for sctting the ac tuatinp clemciits differentially. Fig. T rep resents a. side elevation of the right-hand end of the machine showing, the operating lever. Fig. 7 represents a detail view of the operating lever in the extremity of its downward operating: movement. Fig. 8 represents a detail viewof mechanism just inside the right-hand side frame of the machine and forming part of the driving mechanism. .Fig. 9 represents a detail view of a portion ofthe Iggy board and the key detcnts.

Referring to said drawings, in Fig. 1 it will be seen that there are four hanks of amount keys 20. a bank of clerks keys 9.1 and three special trans-:u-tiou keys 22,.thcse kc representing the usual special trans actions such as received on account, charge, and paid out. After the desired keys have been deprc scd for the entry of any particular transaction. the operation of the machine is completed by means of an oscillating: operating lever 23. The inter mediate connections between this lever and the driving shafts of the machine arc of a certain novel form by which the oscillatory movements of the lever are transformed into arontinuous rotary movement of a driven shaft, all of which mechanism will be dc scribed in detail later, it being sutllcicnt to state at present that upon a complete oscil latiou of the lever downward and backward, one complete revolution is given to a main lower open-ting shaft 24 (see. Fig. 2) which shaft has fast upon it a gear wheel ilfiincshiug with a gear wheel 26 fast upon an upper'opcratinp shaft 27. Thcrc is fast upon the lower shaft'tll another gear wheel 28 (see also Fig. l), which meshes with a gear wheel 29 fast-upon an auxiliary operating shaft 30, the purpose of which shaft will be explained later. All of these shafts are driven by said opcratinc lover and are tit) s end of the machine as shown in Fig. 2 there given one complete rotation at each operation of the machine in the direction shown by the arrows in Fig. 2.

Situated in the rear of each bank of amount keys 20 is a main actuating element 40 (see Fig. 5) in the shape of a lever having at its upper end a segmental rack 41 for the purpose of actuating the accounting devices as later to be described, this lever being pivoted loosely'about a transverse shaft 42 at the lower forward part of the machine.

This main actuatin element 40 is adapted to be positioned di erentially rearward under the control of the amount keys and then to be restored to normal forward position, during which restoration itis coupled u to an auxiliary setting segment 43 whici is also pivoted loosely upon the transverse shaft 42, having a slotted connection with said shaft permitting the segment to he raised vertically. The upper end of this segment 43 is formed with a segmental rack 44 adapted to, engage the teeth of a projection 45 formed on the side of the corresponding lever 40. The segment 43 is also formed atits middle rtion with a slot 46 through which exten s a transverse restoring bar.47. Each of the amount actuating levers 40 is formed on its rearward edge with a restoring shoulder 48 which projects in proximity to the restoringbar 47 This restoring bar is carried between the two arms50 of a restorin frame, these arms being bifurcated at their lower ends to straddle the aforesaid shaft 42. The exact shape of one of these arms 50 is shown in detail in Fig. 5". Extending from said arm is a link 51 carrying at its rearward end'a pin'52 proiecting into a cam groove 53 formed in a disk iast upon the lower operatin shaft 24 so that u on the o eration of tie mashine the Jim 51 will e reciprocated forward thereby carryipg forward the restoring bar 47 which strlkes u on the shoulders 48 of all of the actuating evers which have been moved rearward and of course restores said levers to normal forward position, and then the. restoring frame is rocked backward to normal rearward position, but the actuatin leversmmain latched in normalposition meims to b'described. Thisirestoring frame'howe'veris given a slight upward movement rior to its movement of restoratiop, fort e purpose of causing the auxiliary segments 43 to be coupled to the acto ating-levers 40 when the latter arerestored to normal. It is to be understood that there is an arm 50 and a rockin link 51 at opposite sides of. the machine or rocking the re storin bar 47, and adjacent to each arm 50 is a-. 1i ing cam-.54, shown in detail in-Fig. 5. Each of these lifting cams is fast upon the aforesaid shaft 42, and at the right-hand extends upward from this rock shaft 42 an arm 55 to which is ivotcd a link 56 having at its rearward em? a pin 57 playing in a cam groove 58 formed 1n a disk fast upon the lower operating shaft 24 so that upon the operation of the machine the link 56 will be drawn rearward and the shaft 42 rocked so as to rock both of the lifting cams 54 rearward. These cams are formed with cam grooves 60 (see Figs. 5 and 5) into which project pins 61 extending from the sides of the restoring frame arms 50, so that when the shaft 42 is rocked and the lifting cams 54 also rocked rearward the entire restoring frame will be raised sli htly and thereby the restoring rod 47 wil also be raised slightly, and since the auxiliary segments 43 rest upon said restoring bar by reason of their slotted connections 46 there. with; the entire series of auxiliary se ments 43 will by this means be elevated s ightl so as to carry their rack teeth 44 into mesi with the pro ections 45 so that upon the subsequent movement of restoration of the bar 47 the restoring movement of all of the actuated levers Wlll carry with them the r respective auxiliary segments 43, of course transmitting thereto differential extents of movement exactly equal to the differential displacement of the actuating levers rearward, this diff ential movement of the auxiliary segment ein in the resent instance utilized for the setting of t e indicators as will presentl be explained,. although of course this differential movement could be utilized for various other purposes for performing the various functions necessary in a cash register. Near the end of the operation of the machine the lifting cams 54 are again rocked .torward thereby piirmitting the restoring frame to descend to uncouple the auxiliary segments 43 from their actuating levers and then the restoring frame is again rocked rearward to normal position and the restoring bar acts to return all of scribed. Each lever 40 is normally under the tension of a s ring,70 (see Fig. 5) sur'...

rounding the sha t 42-and tending to force the upper end of the lever rearward. Alug 71 formed on the upper end of thedever has a tooth adapted to enga e a notch 72 formed in the up er and of a ey detent'plate 73. Key pins 4 extending from the sides of the shanks of the amount keys are adapted to ing lever 40 and prrmit the same to spring rearward; but it will be observed that these beveled noses T5 are differentially g adrrl so that the key pins of the different lteys act upon the detent plate at l'rrrnt times with ruspeot to the ("r-rt i key move-merit, and thereby anlatrh the actuating lnvnr it) at different that arroltling to the ralae of the key (leprrs, '1 that is K 'lln key is the npprrmwt key in lb 7 i L a pin is arranged so as to strike the proico tion 75 only near the extremity at tho ini-- tial movement of the key and thereby the lever 40 will he rrlcaaa l only hoarthe end of the movmnrnt of ilepra si-oi of the 1 key, whereas the 53 he will ieleasr the lever somewhat sooner and the: 3 key still sooner and so on, Thus sinre t he i key is to etlfrrt the movement of the art sat lug lover ll? only to one degree roar 'ars'l. it is not necessary to release tho lrier until near thc end of the movement of tho key o'hcr as for the;- 9 key in this bank. tlu lever i is, to have a much greater extent of rearward inovrmcnt and of course must be released almost as soon as V the 9 key is dcprrsscd.

In order to release the depressed keys by tho operation of the machine, each (lctcnt plate is formed upon its rearward side with a projecting arm carrying a pin 78 engaged by an arm 99 fast upon a rock shaft no. from whirl: shaft as shown in Fig. .2 there amends an arm 91 pivotally attached to a link 92 carrying at its rearward end a pin 93 acted upon by a cam 94 fast upon the upper operating shaft 27 so that at each operation of the machine the shaft 90 is rocked to release all of the depressed keys prior to the movement of restoration of the actuating levers 40. A lug 95 on the side of the link 92 cooperates with a projeotion 96 on the shaft 27 to lock the machine while any key is being moved from its initial to its linal position.

in Fig. (3 a modiliud form of manipulati ie means is shown for positioning the actuating levers 4O ditl'erentially. This form rtmpriscs a setting lever 100 which is fast to a segment 101" )ivoted loosely upon the aforesaid rock sha t 90 and meshing with a segment rack 2 attached to the side of the aetnating lever In this manner the set ting lever 100 is positively geared to the actuating lever ell) and by being lllUYtil mar A a on the front of the machine may be a notch 82 tornwl in the Mal of a stop plate upprr position since they are always in gear with the actuating levers 40.

For the bank of clerk's keys 21 there is 'as shown in Fig. 4 a main actuating lcvrr 110 but the upper end of this lcvcr docs not have any rack teeth formed thereon since it is not used to actuate any accounting do tires. but the lever has cooperating yith it the usual auxiliary segment 43 for the purp se of ting the clerks indicator. This rlt-z writinglever llt) has at its upper end a pin ill projecting into a can: slot ll! The key formed in a rocking lever 113 pivoted upon the upper shaft '27 and provided with a dmvnwardly extending arm 11 1 projecting into the path ofa pin 115 fast upon a disk attached to the lower operating shaft 24 so that it is necessary to press one of the clerks keys to rock this locking lever out of the path of the pin 115 before the machine can be operated.

The particular mechanism for setting the indicators will now be described. As shown in Fig. 4 each auxiliary segment 13 has extending rearwardly therefrom an arm 120 to the lower end of which is pivoted a link 121 which at its upper end is pivoted to the foru a rd end of a setting lever 122, to the other end of which iever is pivoted a link 1523 atlachctl to a hell c'auh segment 121 having at its upper end as shown in Fig. 3 a segmental rack 12-3 for meshing with a pinion on the side of the indicator 12$. Deljiending from the middle point 130 of the setting lever 1'32 is an arm 131, which swings loosely upon its pivotal point 130 and is suitably slotted to permitthe extending therethrough 'of'the shaft 24. On one face of this arm and near the pivotal point is an anti-friction roller 132 and upon the opposite face and lower down another antifriction roller 133. These rollers are adapted to be acted upon by duplex cams 134 and 135, the cam 13+ acting upon the roller 132 and the ram 1215 acting on the roller ll).

\l'heh the auxiliary setting segment 43 is carried f rward and positioned (litter-ctr tiall v in the manner hitherto described. the linh 121 is thereby raised to a certain ex tent and the point of attacluncut tilt of this link to the lever I23 is thus moved to a certain point. After the segment 13 has been moved forward in this manncr and is held locked by engagement with its correspond ing actuating lever. this of course holds the point tilt in a lined position and this point now ecomes a fixed fulcrum point for the indicator setting lever 12;! and the intermediate point tilt") becomes the point of ap plication of power. the cams 131 and 13.) acting upon the rollers 155i and 133 to hring the bar 1231 to a constant position so that they point of application of power namely the point 131 is at each operation of the machine brought to an unchanged location of rest since of course the duplex cams always pperat'r to position the bar 1111 to the same point. Since the fulcrum point during this time held fixed. this movement of the point of application of power effects the ditl'crcntial setting movement of the link 12 3 and thereby sets the indicator ditl'erentiall to an extent exa tly corresponding to the ditlercutial m vement of the setting segment 43; As soon as the indicator is set it is suitably locked in position by a locking and alining pawl 137 (see Fig. fast upon a rock shaft 138 which shaft is rocked by means of a cam 139 (see Fig. 8) fast upon the upper operating shaft 27 and act;- ing upon a pin 139 projecting from an arm extending downward from said shaft 138. After the indicator is set in this manner and then locked in position, the aforesaid duplex cams have completed their operative nniuements upon their respective rollers and near the last part of the operation of the machine these cams are free from their rollers, the normal position being shown in Fig. 4 so that the bar 131 is free when the auxiliatg segment 43 is restored backward to normal position. the fulcrum point 136 also returns to normal position, the lever 122 assuming a certain angle according to the height. to which the link 123 has been aised for setting the indicator. Thus the indicating setting lever 129/- serves as a power apydication bar or lever, and at each operation of the machine the fulcrum point; 136 moved dill'erentiall and then held in fixed position while the point of application of power namely the point 130 is brought to an unchanged location of rest and thereby the indicator is properly po oned. This indicator setting mechanism results in the setting of the indicator without the necessity of the indicator being restored each time to zero position. and is in general re spccts vcry similar to that described in the (".I)-1)tillllll application tiled by the same applicant on Sept. 12. 1903, Serial No. 172.970: however in said co-pcndiug application the indicator setting duplex cams are carried upon two separate shafts above and below the point of application ofpower whereas in the present instance the said duplex cams are both mounted on one and the vsame shaft. it bring intended to claim the broad subject mathr conunon to these two cases in the aforesaid co- 'iending appli- *ation.

The mechanism for a tuating the accounting devices from the actuating levers 40 will now he described. As shown in Figs. 3 and 4- lhc rack teeth 41 which as hitherto incntioncd are formed on the upper ends of the actuating levers 1H for the amount keys, mesh with gear wheels 110. Each of these gear wheels 110 mounted upon a. collar turning loosely on the transverse shaft 141, and mounted side by side with this gear wheel 140, as shown in Fig. 1 is a companion gear wheel 142 also mounted upon a collar and turning loosely upon the shaft 111. This companion gear wheel A42 meshes with a pinion 1. 13 of its corresponding countcr wheel 141. Since the actuating lever 40 is thus not directly connected to its corresponding counter wheel. the rearward setting movement of said lever has no effect upon the counter wheel but upon the movesaid eon'un nion gears while the aetuatingl lever it] s being set and lining roeked into nieslrlrv the operation of the ma hine prior 1 to the reatoring HlUYtIlitIll of said lever. ()t' eourse there is one of these idle pinionS and pairs of companion gears for each counter wheel and aetuatine leve and all of the idle pinions are mounted upon the same transverse shaft Hit. and the means for rocking these idle pinions into mesh with their roinpanion gear wheels as follows. The transverse shaft 146 earrving said idle pinon s mounted hetu'een arm 150 extending;- n :Htl from a rot-k shalt 1551 (see Fig.3). and hiosely upon the aforesaid roek shaft t ifi a hell Prank lever 152 having a hori Lwui ai rearwardlv extending arm earrying a poi i321 projecting into awa'n groove 1.5 i'i-iwned in a disk fast upon t r= upper operah halt QT. and having a vertical and don i'twardly extending a rm 155 upon the end (it uhieh is a pin 156. This pin projeels into a slot 1.7T termed in the lower rearward ell-4" ol another hel'lyrank lever 13R whieh is pivoted at 1511 to a 'lorwardly extending aim t whit-h forms one arm of a threw urine-l 1lt'\ll"t,' lln upper arm of \\llitll is the alor-siid arm l t earrving the idl pinion row-i: shalt. :itli'l the third arm of whit-h terminai in a eurria'l or hooked projeetion i131.

When the parts are in the position shown in Fig. the rota Jti of the shaft 27 rot-k. the \erti al arm of the hell eranh lev r 15:

p rinlrward and tliert-hy through its pin 156 pulls r ain'artlly on the hell eranit lever l'. whit-h is ilit'tllttll i' atturheil to the arm 1G0 and therelrv said arm llvt) is rorked downward .ttl l the rneit shaft it is also roeked and the :trna iii} are rot-hurl forward to throw th idle pinions sin'niltaneously into me h a ith their respective companion gear u'luah so a to eonple said wln=els together and muse the aetnation of the wunter. on th other side of the same disk whieh carries the tlllli groove 15?. is a pin i Wllitll when h maelrine is at rest liloi-ks the third arm E and gut-rents the downward rocking of arm li l to earry the idle pinions foras would tend to wear when the enunt r thiowoul HHt'ltiiHh-tt'] is operated by one ot the s ng-rial tran -artion keys as will now he ih-serihed.

For the purpose of preventing the operation of the eounter when any one of the .s iw'irtl transa tion keys is operated. the actuatiniz l ver lT 'l (s e Fig for the hank oi spet-ial transaetion keys trike npon a pin 1?] projettting from the unnardlv extending arm of the aforesaid 32. la arranged to i hell erauk lever 158 so as to rock said bell crank lever upon its pivotal point 15. and withdraw the notch 15? from engagement with the pin 156 so that upon the rocking of the hell crank lever 152 in the manner ahove deserihed, the pin 150 will no longer pull the hell erank lever 158 rearward and thus the idle pinions: will not he rocked into mesh with their eoi'upanion gear wheels since these gear wheels are no longer coupled to; gether. and the 1't."-lt rin 9 movement of the urinating lever will not he transmitted to the counter wheels. Upon such upward melting of the rearward arm of the hell erani; lever 158, a notch 1T2 in'the other 1 edge thereof engages a stationary pin 17%) 1 and lot-ks the hell crank lever 158 from movement and henee looks the idle pinions from being swung forward. It is unders ood of eonrse that the actuating lever 1T0 forthe three special keys has no raelt teeth formed on its upper end since this actuating lever is not utilized for aetuating any accounting derives but simply throws out the counter and in addition has eoiiperatingwith it one of the auxiliary segments 43 for setting the special transaetion indicator.

The various eollnter wheels are mounted open a transverse rounter shaft. 180 (see Fig. it}. whi'h shat't may he formed with the well known provision for resetting $18 i'onnt r wheels to zero. sneh for example as a grown in the shaft torengaging springreiq-eil pawl:- carried in the counter wheels and pieldun; up the eounter wheels and re setting the ame to zeronpon the rotation i of this tlHtrtwZti'u shaft. Fast upon the end of the zero resetting shaft 180 is a disk 1R1 earryinn a pin 1S2. Resting upon this pin is a lever IRS-suitably drawn downward and rearward hy means of a spring andhavl1); {'2\ slotted pivotal pointatit Forward end to permit longitudinal movements (ll the, lever.

A looking lever 190 (see Fig. 5) pivoted ati'its middle point has a nose upon the upper end thereof projecting into a dish and zero resetting shaft 18 so that. while said shaft is turned during the (an-ration of resetting the counter to zero, thia nose will be forced rearward, and the lower end of said locking lever will he fUlt'ttl into the path of a shoulder 191 formed in one of the previously (ltPC'l'lllQtl disks carried upon the lower shaft 21 so as to loel: the marhine during the zero reaetting, movement.

In eonnection with the operation of the eounter wheel a novel form of transfer mechanism is provided. Each counter wheel has the usual tripping pin 200 on the side thereof (see Fig. 4i which pin is arranged to strike the f rwardly [)I'ttllt'tllltj none of a tripping pawl 20!. which pawl is formed with a shoulder 202 for supporting a log 903 proieeting laterally from a transfer pawl Q04 Wllti'll tranofer pawl is carried upon (hr-upper end of a hell (rank lever 2H5 pivoted upon a transverse shaft 206 and having; a downwardly extending arm rarry ho: a pin 20? projerting into the ram groove 903 formed in a transfer operating dial; 20.! faat upon the upper operating shaft 27.

The driving merhanisu'i will now be deaerilled. with reference to Figs. 7 and 7. The aforesaid operating lever 23 has [or its pivrtal hearing a atuh shaft 300 which shaft in mounted in the upper portion of a rocking plate 130] auitaldv pivoted at 302 to one of the side frames of the machine so that upon the swinging of this plate 301 on its pivotal point 2102. a roelcing pivot is proided for the osrillating operating lever. P ant to the lever is an rmerating rark 303 the teeth of \vhirh are arranged to mesh with either one of the two gear wheels one of which it); is fart upon a stul) shaft suitably journaled in the idtframe of the machine, and the other of which 805 is fast to the outer end ot' the at'oreaaid lower operating sliaft 9 L. lheao two gear wheels are in meal: with rarh other and the lever rack 303 is adapted to he thrown into mesh intermitmay with said gear wheels so as to transmit a eontinuoufi rotary movement to the gear wheel 305 and uhaft Q-l upon the oscillatory movements of the lever 23.

\Vhen the lever is in its upper normal po aition shown in Fig. 7 and in grasped to be pulled forward and dmvnward, the lever would naturally tend to rock on its rocking pivot so an to throw tho operating rack 303 fin-ward into meah with the gear Wheel 304 and out of mesh with the gear Wheel 305 so that as the lever is given a complete oscillation downward to an extent of 90 the gear the direction of the arrow, and through this near wheel will give a half rotation to the {50:1 r wheel 305 in the direction of the arrow, thr extremity of this direction of oscillation living SllUWH in Fig. 7. Now when the le \rr started haekward by hand the upward and harlnvard force on the same would naturally tend to throw the operating rack fltlil haelnvard into mesh with the other gear wheel 305 sothat no the lever is then rest red upward to normal position, said gear i wheel 53 )5 would be rotated in the direction shown by the arrow, and this will complete wheel flfll will he girth a half rotation indownward oscillation of the lever, so that a 3 complete revolution will thereby be transposition shown in Fig.

mitted to he gear wheel 305 and driven shaft 24 upon this oscillatory movement of the lever 23. A spring 307 suitably wound around the pivotal point of the lever and attached thereto normally tends to restore the lever to upper position.

A re'taimngpawl 310 engages the teeth of the gear wheel 304 so as to prevent backward rotation of the same. It will be seen that the off :t of this retaining pawl is positively to compel the rocking of the lever upon its pivo al point upon the reversal ofthe oscillation of the lever. That is, for example, if the operator should while the lever is in its upper position as shown in Fig. 7 try to hold the pivotal point of the lever backward and then pull the lever downward this would tend to rotate the ear wheel 305 reversely to the direction of t e arrow and thus rotate the gear wheel 304 reversely which reverse rotation is prevented by the retaining pawl 310 so that the ORIy POSS IblB movement of the lever is the rocking movement of the same on its pivotal point to throw its operating rack forward into mesh with the gear wheel 304 so that then upon pulling forward and downward on the lever the gear wheel 304 is turned in its proper direction; and

similarly if when the lever is in its lower 7 the operator should attempt to hold the pivotal point of the lever forward so asto maintain the melt 303 in engagement with the gear 304, and then rock the lever back to upper position. this reverse rotation of the gear wheel 304 would be prevented by the retaining pawl 310 so that no movement of the lever would be possible except the rocking movement of the pivotal point of the lever rearward so as to carry the raek 303 properly into engagement with the ear wheel 30.) and thus eomplete the rotation of the gear Wheel 30l in the proper direction, so that by this means when the level-reaches the extremities of its oscillatory excursions the reverse movement of the lever must be accompanied by the attendant rocking of the pivotal point of the lever to carry its rack into mesh with the proper gear.

Assuming now that the lever 23 has been pulled part way downward and of course in this downward movement has been rorlied forwardon its pivotal point so as to throw its rack 303 into engagement with the forward pinion 304 and thereby rotating said pinion partiall thenif it were possible to rock the pivota again to its rearward position, this would throw the rack 303 back again into mesh with the gear wheel 305, and then if the lever 23 were restored to normal position point of the lever backward this would turn the gear wheel 305 in the proper direction as permitted by he retaining pawl 310 but the lever 23 and gear wheels would then be out of proper time with each other for the lever 23 would then he in normal upper position while the wheel 30-"; told be partially operated. Therefore merhauism is provided to lock the )l\'- otal point, of the lever in either one 0 its suitud positions dining the extent of the operative movement of the lever, that is, after the lever has on aubeen shifted on its pivotal point and has een started on its operative oscillatory movement, this mechanism being shown in Fig. 8. livoted at 311 to the side frame of the machine is a pallet ill) formed with two teeth 313 and 3M pro-.' jet-ting into proximity to the shaft 24. A pin Ill-,3 projects from the llforesaid rocking plate 301 (,whirh carries the rocking pivot for the lever), and extends through a recess 310 formed in the side frame and engages an enlarged slot 317 formed in the middle portion of the pallet 3 2. Fast upon the shaft it is a locking flange 318 having two shoulders 1% and 320.

When the lever is in normal upper position show u in Fig. 7. the pallet 31:! is ill the position shown in Fig. 8 with its tooth 313 engaging under the shoulder 319 of the looking tlange IHH. Now as the lever 23 is pulled forward from normal upper position, this will draw the pallet 3i: forward and withdraw the tooth 313 from engagement with the shoulder 310 to permit the proper eontinned rotation of the shaft 24 in the direction shown by the arrow in Fig. 8. Now when the lever has been pulled downward its eomplete extent to horizontal position, the ltulilnf," shoulder 310 is rotated half way around and strikes. against the underside of. the pnllex tooth 314- whieh obviously has been nimeil forward with the forward rocking movement of the lever pivot {to that the striking of this shoulder 310 against this tooth 314- limits the downward movement of the lever 23; and when the leveris now thrown backward to normal upper position, the initial l'til'klllg movement of the pivotal point of the lever carries the pallet 312 back to nornuil position thereby withdrawing the pallet tooth flllfrom looking position in the path of the locking shoulder 319 and permits the continued rotation of the shaft '24- and flange 31S bark to normal position' and of course the pallet tooth 313 has in the meantime been brought into its rearward normal position shown in Fig. 8 so that at vthe end of the upward movement of the point of the lever while the lever is in an intermediate position in its excursion of 0s cillatory movements; that is, after the allot 312 has been rocked forward just be ore the lever, is started downward, then eontinuing the downward extent of movement of the lever, the periphery of the flange 818 stands in the rear of the allot tooth 313 so that the pallet cannot e rocked backward because of this locking surface of the flange 318 until the lever has completed its downward excursion whereupon the flange 318 is turned so far that the shoulder; 320 thereof lies just below the pallet tooth 313 so that now the pallet can be shifted rearward for the normal operation of shifting the pivotal point of the lever backward preparatory to the backward oscillatory movement of the lever itself. In order to prevent a too sudden rocking of the pivotal point of said lever between the opposite directions of movement of the lever as above set forth, a retarding device is provided shown in Fig. 8. Pivoted at 330 upon the side frame of the machine is a gravity pawl 331 oarrying at its rearward end a pin 332 arrange to coiiperate with the rearward edge of the aforesaid shifting pallet 312. Fast u on the previously described'osciL latory s aft 30 (which it will be remembered is given a complete revolution at each operation of the machine by means of the gearing shown in Fi 2), is an arm 333 carrying a pin 334 which is in alinement with the gravity pawl 331 so that upon the operation of the machine the pin 334, revolving in the direction shown by the arrow, strikes the end of said pawl 331 and raises the same so that it now stands in the rear of the pallet- 312, this taking place upon the downward stroke of the lever when the pallet has been shifted forward to permit the pin 332 to be raised without contact with the pallet. At the end of the downward stroke of the lever the pin 334 rides out from under the gravity awl 331 to permit said pawl to drop by its own weight, and at this point it the lever were too suddenly thrown u ward for its return movement, this woul(l at the same time start the pallet 312 rearward and if the gravity pawl 33l had not, in the meantime dropped to normal lower position, the pallet 312 would strike against tie pin 332 and prevent the backward Slllfl'lt'); move ment of the pallet and thus prevent the lever itself from being thrown upward into normal position. By this mean the lover cannot be made to pass its halt stroke downward position too quickly since time enough must he allowed for the gravity pawl 331 to drop to carry its pin 3352 out o l' the path of the shifting pallet, and this prevents abuse of the machine by a too rapid oscillation of the lever since when the lever has reached its horizontal position the hand pressure of the same to return the lever normally tends to rock the pivotal point of the lever backward and if this movement is exe outed too quickly injury to the parts or manipulation of the machine might result were it not for this retarding device.
