A second rod or wire 6 extends from side to side or the maehiue and cooperates with the rounded portion .l on each oi the key levers, which rounded portion is substantially concentric with the pivot wire T whereas the key levers are guided in their vertical movements by a guide eomb u.

An opening 2b is provided within the vibrator to ail'ord an impact oi the type against the ribbou as it moves through the ribbon guide or vibrator. center type guide, comprising guide arms 29. is rigidly secured to the type bar segment 1-30. These. guide arms extend upwardly and rearwardly in opposite directions-to points adjacent to the printing'point and each arm terminates in a guide tat-e31 with which the type bars cooperate to properly guide them in their movements tothe printing positions.

A. spring drum '7! is supported and illlil])l.- ed in revolve on a spindle Tllihat receives its support; from one of the standards l.

The opposite end of the shaft 32 has a driving pinionfi l secured thereto and this pinion meshes with a driving wheel H 'mvhieh is provided on. opposite sides thereof with oppositely disposed engaging projections or pins 556 which are circularly arranged, as indieated in Fig. 8,'and are spaced at regular distances apart.

A hearing is provided in a standard for a shaft 87 that has a. collar 88 thereon to prevent. a longitudinal movement. of the shaft in one direction. The inner end ol the shaft 87 has secured thereto a rihhon spool 89 that is adapted to hear against the standard 3 and prevent a longitmlinal movement of the shaft in one direction. so that the collar 88 and the rihhon spool 8t) eoopcrate to prevent a. longitudinal displacement of the shaft; 8T. crank arm )0 is secured anda linger arm in order for turning the rihhon spool piece ill is secured to the c anlt to afford means HS) hy hand.

The standard 3 has a hearin for the reis alined with i the shaft 87. The shaftfl) supports a rih- Y spool hon spool 93 which carru a pin M- in the hub thereof, said pin extending into a spline groove 95 in the shaft a2, tlms forming a connection hetween the shaft and rihhon )3 that causes thcrihhtm spool to turn with the shaft but alfords a longitudinal movement of the shaft independent of the spool. The hub of the spool 99, is extended hoyond one of the flanges thereof and has a peripheral groove 96 for eotiperation with an engaging finger 97 that. is secured at 98 to tne standard 3 and prevents an axial movement of the rihhon spool )2} during the longitudinal movement of its shaft hut a flords a free turning movement of the spool with its shaft. This shaft 92 is provided with twojpm'ipheral grooves 99, in either at} which the free end of a latch 100 is adapted to engage to n'llllllftlllttllt! shaft. 9-3 against 'longitudinal disl'ilacenamt. The latch consists merely of a linger which is pivoted at 101 and isadapted to he turned on its pivot into or out of either of the grooves 98) in the shaft. a

The rihhon spool 9 is provided with a projection or pin 10) on the flange thereof :uliaeentflto the driving wheel pin is adapted to project into the any of the projeetitms of pins 86 driv,i'ng wheel.

path of on the. The rihi'io r spool 89 is like.-

wise provided with av pin hr projection 10?,

on the [hinge thereof which is adjacent to the driving wheel and. this pin is likewise adapted to engagethe pins 86 on the driving wheel. I i will he observed thatattte drivinglhviheel'tih S5 and said i. l l

From an examination of Fig. 7 it' driving wheel.

is loosely mounted on the inner end of the shaft J2 and is prevented from axial dis placement on the shaft hy collars 104 secured to the shaft on opposite sides of the The shaft 92 is also provided with a crank arm 105 that has a tinger piece 106 by which the rihhon spool J1 ma v he turned and by means of which a longitudinal displarem t of the shaft 9'). may he ell'ectcd. This longitudinal movenu-ait of th shaft 915 is effective to produce an axial movement of the driving wheel 85 and such axial movement is effective to throw the pins H on one, side of the driving wheel out of cooperation or engagement with the pin ill). or 103 of a rihhon spool and to throw the pins Htf on the opposite side of the driving wheel into engagement with the engaging pin on the other spool. .The gear wheel 87. as heretofore pointed out, meshes with the driving pinion 84 which is of such width as to afford a eonstant engagement hetween the driving pinion and driving wheel, irrespeetive of the axial disposition of the driving ivheel.

From the foregoing description, it will he understood that either rihhon spool may he turned through its crank and tinger piece in order to effect a manual feed of the rihhon. During the operation of the machine a stephy-step movement of the carriage in the diiection of its feed is ellecti've to turn the. gear wheel T'lthrough the pawl 75 on the spring drmn. This movement of the gear wheel is trai'ismitted through the pinion 77, shaft 78, hevel gears 80 and 81, shaft 82 and driving pinion W; to the driving wheel 85. and the rihhon spool which is engaged th n with will he. rotated to effect a longitudinal feed of the rihhon. During the. return movement of the carriage from Left. to right the pawl To rides freely over the teeth of the wheel 71 and the rihhon feed'mechanism remains at rest. \Vhen an end of the rihhon has heen reached, it'isanerely necessary to release the latch ltltl. and move. the shaft J2 longitiulinally in o'rder to effect an axial movement of the driving wheel 85 to shift it out of engagement with the 'rihhon spool on which the lll')l)()ll.l|:ln heen full v wound and to elleet. an engagement of thedriving wheel with the empty spool. 'The latch is then turned into a depression .lJ to lock the shaft 92 against accidental longitudinal displacement and a further feed of the rihhon is'etl'eeted on the emptyspool.

lt will he seen that the rihhon spools are arranged side hy side onindependent alined the movement which el'l'ects a conneetit the pa rallel tween the driving wheel and one ribbon I that interposed between and is situated SPOOl at the same time effects a disconnection between the driving wheel and the other spool, and that I have provided ribbon mechanism which is simple in construction and etlicient and positive in use.

lVhile I have shown the features present invention applied to a visible writing machine of the character shown in my applications Serial Nos. 13,773 and 640,951, it should be understood that, from certain aspects of the invention, and so far as certain features thereof are concerned, it is imma; terial what type of machine the invention is applied to and .it should be further unden stood that various changes may be made without departing from the spirit of my invention.
