The particular form of transfer mechanism employed for this purpose may be found in an application filed by me July 18th, 1919, SerialNo. 311,726.

l attain these objects by ythe mechanism illustrated in the accompanying drawings, in whicli.-

Similar designating numbers indicate similar parts throughout the several views.

In the above mentioned applicationis described quite fully the mode of operation of the transfer structure embodied `herein and the inter-relation of the various parts in eflfecting len masse `movement ofthe digit wheelsy to ywhich transfer movement isV due.

The transfer device consists of the bellcrank 1, composed of a downwardly extending arm 2 and a forwardlyfextending arm 3.

Olne.y ofthese bell-cranks yis locatedadjacent each digitl wheel and" is pivoted tofafsiipport l which extends from the base-plate V5. For convenience of description the digit `wheels are designated 6, 7, 8, 9, and 10. The

The pivotal arrangement olf links 12 and 13 with keach otherV and with the lrod 11,' provide what is' known as a toggle. The wheel axis rod 15 is ordinarily'fixed inthe side frames o f the machinefand which are` not shown herein. The setting link 13',V arranged alongside the bell-crank v1, issup'plie'd with a slot 16 that is engaged by a pin 177, which .preieete laterally from the arm eelreep'oneling to the next higher order wheel.' The slot 16 compensatesv for the` radial swing of the arm 3 on its pivotalsupport and' for the longitudinal and angular .oscillations described by the link 1,3.

A feller Stud v18 is attached, te the Pivetel connecting point of link 13'with the link and ,Herlliey'reste .ee'eheivn in Fg- 2, against the inner end of a lspiral transfer spline 19 which is attached `to the jside of each digit wheel. The spline 19be`ginning at its innerend,l or that end which is'nearest the axis of the wheel, forms a volute whose other end is preferably flush with the periphery of thev wheel, and when the'wheel is being' rotated from Zero position, 2, to the Zero position, 3, the stud 1,8`Wil1 be cammed outwardly, or away from 'the axis of the wheel, and the link 13, conforming with this camming movement, will slide its yoke 14 upon the wheel axis rod 15. The pin 17 engaging in the slot 16, causes the arm 2 representing the ynext higher order wheel, to be moved to the displaced position shown in Fig. 3, and as the stud- 18 passes over the outer end of the spline 19 the spring Q0, which extends from the base 5 to the rod 11, will restore the parts to the position illustrated 'in Fig. ,2, resulting in 'transfer beine eeefefl 'fr'em Wheel .7 t Wheel' i In any otherthanzero position ofafwheel templi-1e 19 will Yhave conforman displaced the members 13` and 12 and the member 2 yfor the Wheel next higheriiltheerder.

but no transfer can be e'ected until the stud 18 passes over the outer end of the spline. Thus all of the Wheels which are variously advanced beyond the Zero position at any particular time Will have their transfers variously displaced, or in a degree commensurate With the pitch of the cam at the point at which the Wheel may be, and this building up7 against the tension of springs 20 will be gradual throughout the rotation of the Wheels. VHowever, if wheel 7 reaches Zero, as shown in Fig. 3, its spline 19 Will. through the link 13, have moved the arm 2 to the position shown, and the connecting rod 11, through the medium of link 12, Will have angularly displaced the link 13 associated With Wheel 8 to the position illustrated inF ig. 4, Whch corresponds to the 9 position on the Wheel. ln effecting this angular position of link 13 for Wheel` 8, the roller stud 18 With which it is associated will be caused to roll one space upon the spline 19 of Wheel 8, and ordinarilj, if the Wheel 8 is in other than position 9, 'Will be moved back one step as wheel 7 transfers to Wheel 8, Without, it should be explained, in anyA degree affecting the position of Wheel 9, for as Will be understood, during the angular movement,

of link 13" to normally vertical position,

Which Will occur simultaneously with consummation of transfer to its associated Wheel 8, it is intended that no change Will be produced in the acquired position of arm 2 for Wheel 9, the slot 16 accommodating the pin 17 to permit such positional re-arrangement. If, however, Wheel 8 indicates ninth position, `as illustrated, When it is to receive an increment of transfer from Wheel 7 the angular movement supplied by rod 11 to the 4link 13 appropriate to Wheel 8 Will have carried the roller stud 18 over the outer end of spline 19rwvhereupon the link 13 will restore longitudinally as shown, for example, on Wheel 9, Fig. 5, and Wheel8 Will then have transferred to Wheel 9.V Coincidentally the link 13, Fig. 4, Will be restored angularly by consummation of transfer from Wheel 7 to Wheel 8 and the parts including the- Wheel Will then'stand as shown in Fig. 2, or in other Words, vbheel 8 will be at O, its links 12 and 13 Will be at normal and the arm 2 representing Wheel 9 Will also `loe at normal. At this operation Wheel 9, unless it stands in the ninth position illustrated in Fig. 5 at the inauguration of transfer from Wheel 8, vviil not transfer higher.

1t will be apparent from the foregoing illustration that those Wheels which are in ninth position and Whose transfers are operated by lovver order Wheels will coincidently operate the transfers for higher order wheels, and if all of the Wheels are in the ninth position they Will be moved en masse to Zero. rFhe operation of the transfer is similar to that iilustrated in the above menioned application in which the transfer is controlled by a toggle and moves the Whee one step through the medium of a pawl in engagement with a' ratchet.

secured to a hub 241, which is pivotally mounted on the journal rod 15. rlhe central or sun gear wheel 25 is rotatable on the rod 15 and remains constantly in mesh with the gear From the hub 24 extend the members 26 to which is secured a ring 27 having ratchet 28 that is engaged by a spring pressed driving pavvl 29 pivotally attached to the side nearest the digit Wheel of a gear sector 30, which is journaled on the hub 31 of the central gear 25 and utilized as an oscillating driving sector to ratchet forward, in definite stages, the ring 27,V whereby the planetary gear 22, in mesh with the stationary sun gear 25, Will be given a rotative movement on its Xis, together with an orbital revolution around the point 15 coaxial with the Wheel 25.

r1"he Wheel 7 is, in this instance, provided with sixty teeth and the gear Wheel 25 is provided Withthirty teeth, although if preferable the pitch diameter of these gears may be differently arranged. rI lie driving sector 30 may be operated by one of the several Well-known driving mechanisms adapted for this purpose, and as the sector is oscillated to rotate the digit Wheel, Fig. 6, one space, the paivl 29 will mesh with the next tooth of the ratchet 28; or if the digit Wheel is to be advanced nine digits the pavvl 29, through the ratchet ring 27, will move the gear 22 an angular distance which Will be equal to nine teeth of the ring 27, which is supplied with fifteen teeth; meanwhile the gear 22 rotating on its axis Will move the digit Wheel the required distance.

Secured to the hub 31 of the gear 25 is a transfer ratchet Wheel 32, provided With fiveteeth, and loose upon the rod 15 alongside the ratchet 32 is an arm 33 which is vin pivotal connection with the bell-crank arm 3 by a link 3e, Figs. 1, 3 and 5. Pivoted to the arm 33 is a transfer pavvl 35 which engages the ratchet Wheel 32. 1f now the setting link 13 is displaced as in Fig. 3 or Fig. 4, the arm 3, through the medium of link 3e, Will move the arm 33 and its paivl 35 to the position shown in Fig. 3, and when the stud 18 passes over the outer end of spline 19 and alloivsthe link 13 to restore longitudinally, as in Figs. 2 and 5, the arm 3 Will also be restored, and through the arm 33 and pawl 35 Will rotate the f tudinal moifeinent of link 13.

Vpair of wheels.

ratchet wheel 32 one tooth, whereby its attached gear 25 will supply an axial rotative movementv of six teeth to the gear 22, and this movement being communicated to the digit wheel will v.advance it one digit. It will of course be immaterial whether the digit wheel is being operated by the sector 39 when transfer is thusy effected, for the result will be accumulative, and as the gear 25 remains motionless, except when utilised for transfer, its purpose will be, if `the digit wheel is already in motion, .to augment -this movement by the additional transfer. When the arm 3 restores to complete the transfer it will finally come to rest with its side against the .ratchet 32 and act as an eifectivemomentum check for the wheel 25.

To prevent retrograde movement .of the wheel 25 is provided a paw-l 36, which is pivoted .to a support 37 yand rests against the ratchet 32, Figs. :3 land 5. The modification shown in Figs. 7 and 8 has a plate 38 .pivoted upon .the hub of the gear 25 and carries upon its outer face the ring 27, the teeth 28 of which are engaged by the driving pawl 29, as in Fig. 6. The planetary gear is, in this instance, pivotally attached to the plate 38, and this plate is provided as shown, with peripheral teeth or notches 39 to be engaged by wheel checking devices not shown herein. In the modications, Figs. 7 and 8, the planetary gear 22 is provided with ten teeth.. the gear 21 with forty teeth and the central gear 25 with twenty teeth, while the ratchet 32 has five teeth and is to be moved one tooth at a time by the pawl 35.

rseferring particuhirly to Fig. 1, it will be noted that in each instance the bell-crank 2-3 'is pivoted eccentric to the wheel axis upon a support 4, arranged between each A connecting medium between the transfer devices is pin 17, fixed in the end`3 of the bell-crank and engaging the link 13 representing the preceding wheel. Any lono'itudinal movement of link 13 is communicated to the next higher transfer set. Longitudinal movement in one direction will be supplied to link 13 when its wheel rotates from position 0, as represented in Fig. 2, to position 0 as represented in Fig. 3j where the stud 18, having cleared the end of spline 19, allows the spring 2O to restore the bell-crank 2 and thereby restore the link 13. The normal position of parts associated with wheel 3, Fig. 2, coincides with the position of parte associated with wheel 6 in 1. Assuming that all of the wheels and transfer devices ot' 1 are in the normal position shown at wheel 6, it will be readily understood by one skilled in the art, that movement of wheel G around to O will cause longi- This movement being communicated through the bellcrank will first set the .pawl .35 in the position shown in Fig. 3, and as wheel `5 passes to 0 the bell-crank, impelled by spring 20, will restore the pawl 35 as in Fig. 5. The

operation will advance the ratchet 32 one 70 tooth and advance the wheel 7 one digit. This mode of transferring is readily understood.

The bell-crank and the linl 13 are inutuallj,1 operative. Lii in moving from normal (l t i 'splacemcnt longitudinally, `displaees the higher order bell-c when stud clears er 19 the kbellcranl will res-tore the in Fig. 2. Another functi t under wheel.
