ent o t may c known that of f bioi and o drawn forwardly in opposition to the spring the latter is placed under tension so that when the handle is released the roch` shaft and the parts connected thereto and con trolled by the reverse movement thereof are restored to their starting points. The connections under control ofthe `roch shaft govern the operation of the usual listing mechanism which, as illustrated, includes the arcuate type-carriers 6 having type 7 movably supported. by the free ends thereof and adapted to be driven by the hammers or drivers 8 to strike the ribbon 9 interposed. between the printing ends of the type and an adjacent platen 10. y

The mechanism for conit'rollino' the operation of the type-carriers and the hammers or drivers 8 constitutes 'a separate invention and such mechanism is not illustrated in detail herein.

Near each side of the machine, forwardly from. the platen, a ribbon spool 11 is mounted upon a vertical shaft 12. The shafts l2 are mounted in bearings 13 and are capable of limited vertical movement because of the spring washers 14C interposed between the heads the lower ends of the shafts' 12 and the bearings 13. rlhe ends of the ribbon attached to the spools 1l respectively, and said ribbon passes against rollers mounted on spindles 16 and is thereby supported adjacent to the front side of the platen in such position that the type 7 may be carried freely across and in front of the ribbon without contacting or engaging therewith. A beveled pinion 17 is rigid with each spool 11.

.fr shaft 18 journaled in bearings formed in removable plates 19 and is axially movable as required to mesh the pinions 2G on the ends of said shaft alternately 17 eapcctively. di ratchet shaft- 18 and is enotally carried by i ringing loosely from at the side'of the ratchet 21. 22 is dingly retained in engagenient withy the 'ratchet by a spring 24 connecting the pav'l with the supporting plate.

The plate 2? has a lateral projection 25 carrying a. roller 26 which cxtendsinto a notch 27 inthe upper end of a lever 28. The lever is pivoted intermediateof its ends upon a support 22) and the lower and of said lever is pivotally connected to a le ver 30 which mounted on a pivot 3l. The lever o0 is roniwcted by a connect-ing link B2 with a member having `its lower end pivotod to the arm or lever Ll and arranged to be rociprocated thereby when the shaft l is rocked. By this train of connections leading' from the rock shaft 1 the plate 23 will be operated in one direction by the forward roclringof the shaft 1 and in the 0pposite direction by the return movement of the shaft l under the inliuence of the'spring 3. This causes the pawl 22 to engage the teeth of the-ratchet 21 successively, so that the shaft 18 will be rotated intermittently inthe same direction, as a result of the rocking of the shaft 1 in opposite directions.l When the shaft 1,8 is rotated it necessarily rotates the spool 11 with which it is entrained. y

vBackward rotation of the shaft 18 is prevented by an abutment 34 pivoted upon a suaft 35 and engaging the ratchet 21. The abutment 34: is retained in engagement with the ratchet 21, by a retractile spring 36 connecting said abutment with a pin 37 eX- tending `from one of the walls of the hous: ing in which the mechanism is mounted. A screw 38 supported by the Wall of the housing passes through a slot 39 in a part of the abutment 34 which extends around the shaft 35 and thus prevents the abutment from becoming displaced.

'A disk 40 is rigid on the shaft 18 and is arranged to coperatie with a device which contacts with the dish to push the shaft 18 axially in order to complete the axial move ments thereof. The device comprises a lever 28a pivoted on the shaft 29 and having pinin-slot connection 30a with the lever 30. The

pin 30a is connected with the lever 30 by a spring 30h, so that when the-lever 30 operates the lever 28a will also be operated. The lever 28 has a pointed cam member 28b on the forward end thereof adapted to Contact with the oblique sides of the disk 40 andthereby push the shaft 18 axially in either direction to complete the axial movement thereof and force the pinions 2O into mesh with the pinions 17 respectively. When the shaft 18 is in the position illust-rated in Fig. 2, axial movement thereof is prevented by a releasable lock all comprising an arm mounted on pivot Ll2 and engaging Within a circumferential groove 43 adjacent to the pinion 20. The arm 41 is integral with an upwardly extending arm 44 which has a slot in its upper end through which the ribbon passes. lt is intended that the ribbon shallbe provided with a clip or other equivalent part 45 adjacent to the end thereof, so that said clip at the proper time will be drawn into engagement. with the upper end of the arm la and actuate said arm rearwardly, thus raising the arm 41 out of the groove 43 to permit the shaft 18 lto be moved axially and connect with the spool from which thc ribbon has been unwound.

i A spring 46 connects a pin 47 on the arm l1 with a rigid part so that said arm 41 is springactuated toward locking position.`

The pin ill? extends through a slot i8 in the wall of hc housing so that the spring 4G is. incased within and protected by the housing. whvfllen the4 shaft 18 is moved to the left LSL) Tse mov we mina :vb one by the Yu 1s plrfleuly efey 5T. e iev-i- 6'? L men' yvhich is eminem :2 am? 1.
