Y

Tho sli-aft l2 extends. from side to side of the machine i and is provided at the left-hand end portion thereof with a bevel gear wheel secured thereto and meshing with "asimilar wheel 21 on the shaft 22, which 'latter'carries the ribbon spool 23 and is mounted toturn in dependlt will be understood that an! of a ratchet wheel 29 carried by a bracket 30 secured to the lower side of the top plate 3. The lever 27 has a pawl' 31 pivoted thereto at 32, said pawl 'engagingthe teeth-of ratchet wheel 29 and as the lugs 26strike Athe innerfree end portion of the lever they cause it to rise and fall and the pawl vibrating back and forth on the teeth -of the,

ratchet wheel 29 cause it to slowly revolve and turn its shaft 28 and a worm 33 thereon. The worm 33 engages l a worm wheel 34v on a vertical shaft 35 carried by the bracket 30, and the shaft 35 at its other or upper end carries'a cantor driving device 36, The spools 23 and 37 slidefreely along the shafts 22 and 25 brit each spool is caused to revolvewitlr its shaft .by'means of a spline .on the shaft or any well-known or desired means which I. have not considered `necessar'y'to show. The ribbon A passes 'from the left'hand ribbon spool up and o ver a pin 38 and then over the typefwell andaroundga similar i guide pin at the other side of the machine to the other ribbon spool. The pin' 38 is carried by two ears l39v of a shifting frane 40, and the latter has depending from its l .-.lower side two fingersv 4l which span the associated spool and control its movementalong the shaft 22. The frame 40 is carried by' tw4 supporting links 42, 43 which I turn on vertical posts 44, 45 secured to theunderside of the top plate 3. These links 42 and 43 are provided at their pivotal ends with sleeves' surrounding the posts 44 and respectively which afford an easy swinging movement ofthe links .while their outerends are pivoted at 47 and 48 to opposite sides of the shifting frame 40 and cause it to move fore and aft of the machine dur- 'ing the swinging movement of the links. This move-v ment is imparted to the links and shifting frame 40 by means of the small arm 49 having a forked end 50 which carriesa `roller 51 designed to ride over the face of cam 36. A spring 52 is wound about the pivot post 45 above the sleeve of the supporting link 43 and one end of the spring bears against the depending rim of vtop plate 3, l the other end bearing against thelink 43 and tending to l force it and the shifting frame 40 with link or lever 42 in the opposite direction, causingthe roller 51 to ride on the face-of cam.36.

Thetop plate supports one end of'a ribbon guide plate 53 of the usual or any suitable construction, the other end of said plate being turned around the rod 38, thereby pivotally connecting the guide plate to the shifting frame 40 and causing said plate to travel 'fore and aft of the machine with the 6o y shifting frame. The guide plate 53 carries two dependy. g ing fingers 54 which engage the spool 37 outside of the v' flanges thereof, so .that a back and forth-movement of the frame 40 and the guide plate 53' causes both ribbon spools to be moved back and forth axially along their shafts and effects a transverse feed of the ribbon. Thev 'the spool 23 along the revolving shaft 22. 40,*through the ribbon guide plate 5 3, also shifts the rib-4 bon spool 37 at the other end of the machine by the de.

pin 38 has a head 55l at one end, whereas the pin is v threaded-at the other `end to receive a nut 56 provided with an annular groove 57 for the reception of the wedgeshaped end 58 of a fiat spring locking device or detent 59 secured to the top'pla'te of the machine by screws 60.

This construction,l there-fore, provides-engaging means on a part that'4 moves with the-ribbon spools and coop! erative engaging means on a fixed part of the machine to hold the spools against axial movement. y,

The inking surfaces, or ribbon Aare shown as two fields, 61 and 62. These fields may be inking surfaces of two different colors such, for instance, as black and red or they may have differentcharacteristics; thus the p field 61 may be copying ribbon, whereas the field or section 62 may be record ribbon, though for convenience the/sections willbe referred to as oftwo different colors black andl red, the black section beingindicated .at 61 and the red section at 62. I

The operation of the mechanism above described will now be explained: The revolutions of the ratchet wheel the directionof the feed causes the lugs 26 ofthe spider 10 to strike the freel end of the lever 27 and the pawl 31 turns the ratchet wheel 29 and worm 33. The worm wheel 34 Ais turned by the rotation of the worm 33 carrying with it the cam 36 whose cam face causes the lever 42 and link 43 to swing about the posts 44 and 45 respectively, moving the frame 40 laterally and shifting 'lhefrarne pending fingers 54 carried by the plate 53.

-8 through the letter space movement of the carriage in- In the present form of this invention the automatic transverse shifting device is effective for but one of the colored sections 61 ofthe ribbon and this particular section preferably occupies about two-thirds of. Ithe width'of the ribbon. As seen in Fig. 3 the end of the spring 59 is disengaged from the groove 57 and the spring 52, bearing against the link 43, forces it with the frame and the other link towards the cam 36 and causes` the roller 51 to bear upon the face thereof'. The cam 36 has two steps 361*4 and a larger `parabolic face 361K. Under these conditions the action of the cam shifts the black section of the ribbon laterally over the printing center during the longitudinal feed thereof and lutilizes -every portion of it. In Fig. 4 the spool shifting frame will be seen to have been pushed. manually to the right and towards the. front ofthe machine, and the wedge shaped end 58 of the spring detent, or locking device 59 engages the annular. groove 57 in the nut 56. A The roller 51 no longer rides on the f ace of cam 36 and the red I section of the ribbon .now passes over to operative po;- sition .where it may coperatewith the type at'. In other words, the' Acam or driving device 36 becomes ineffective to actuate the parts and an automatictrans-4 yverse shifting action of the ribbon is dispensed with v whenthe red field of the ribbon isnt the printing ce'nter, although Vthe longitudinal feed of the ribbon con-' tinues. Thus, means are provided which may be ren dered' operable at will to effect a transverse feed ofthe ribbon as well as a longitudinal feed thereof and which are 'operable at will to give merely a' longitudinal-feed of the ribbon.` The operation of the cam driving mechanism continues but the lroller 51 is moved from the pitch of the faceofthecam'. When the operatorvagain has occasion to use the black held 6l itis merely necessary to release the catch or holding device 59 when the spring 524 will force the shifting fra-me 40, the ribbon guide and spools towards the rear of the machine until they are arrested by the roller 5lv contacting with the. cam 36 andthe black field will thus be brought to the operative position,

The invention is particularly available. in cases where the red ink or inking field 62 is used but little, or when 10its limited use does not require the employment o1"- n'ieansiorfeffecting an automatic transverse feed of the ribbonlaswell as a longitudinal feed, as for instance, Y.when ink of a distinctive color or 'characteristic is to be occasionally employed. During the operation oi these ll devices, it will be kobserved that the lengthwise motion A ofthe ribbon in either 'direction is i'n no way interfered with and the change of color or character of theprinting surface is readily effected without touching theribbon. While a single ribbon o r inking surface is here shown and described, it is obvious that I may employ two or more ribbons or other inking surfaces,4 each of av single but different color or character.

` From the lforegoing description it will be observed that I have provided simple and eflicient means for affording an automatic feed of the ribbon orvinking surface in tWo directions at substantially right angles to each other and that the feed is nevertheless such thatl 'only the field which is in the operative position win be', presented to the types for cooperation therewith; that A3() the guide plate 53 and the associated parts constitute a ribbon carrier which is operatively connected to and is 4actuated by the means for automatically moving the 'l ribbon in a direction transverse to its length.

Various changes may be made Without departing h'om the spirit of my invention and certain features may be yemployed without the others` 'What I claim as new and desire' to secure by Letters Patent, isz- 1.
