drum 2 is supported at the rear of the machine upon a stud 3, which is securedv to a bracket et depending from the top late, and a strap 5 connects this drum witii the carriage, (not shown,) in the usual manner. Two ratchet wheels G and 7, and a pinion 8, all rigidly connected, are also journaled upon the stud 3 and held thereon by a screw 9. A movingl pawl 10, pivoted to the spring drum, engages the ratchet wheel 7, so that the ratchet wheels and pinion will turn with the drum when the carriage moves to the left, and a holding pawl 11, pivoted to the spring d1'um 'b1acket, engages the ratchet wheel (l and prevents rotation of the ratchet wheels and pinion, while the carriage is beingr drawn to the right. The pinion 8 meshes with a gear 12, journaled upon a stud )rojecting from abracket, 13, depending rom the top plate, and a spiral gear 14; having teeth cut about at' anv angle of l5 degree is secured to and rotates with the gear 1 This gear 111 meshes with 'a similar gear 15 upon the ina-in driving shaft, 1G, for the rib,

bon mechanism. By reason of the reducing gearing between the shaft 16 and pinion S, the shaft rotates at a much slower speed than the pinion, giving a slow movement to the ribbon. The shaft 16 extends transversely at the rear of the machine and is journaled at its ends in arms 17a of brackets 17 which are secured to the top plate of the machine. geared at its ends to a pair of iexible shafts a and b, projecting forwardly at the'sdes ol the machine, by bevel gears 18, as shown in Fig. 1; The shafts a and b each consists of two sections flexibly connected together. The shaft l? consists of a shortsect-ion or spindle 19 journalefl in a bearing 20 in the bracket 17 at the right side of the machine,

' and a section 2l, connected at its rear end to the short section 19 by a universal joint 2Q, and having its forward end journaled at Q3 in the laterally projecting arm 24 of a bell cranklever 2f-i. The bell crank lever 24- is jonrnalcd upon a stud 25 which is adjust ably scoured within a bracket Q6 by means ot' a set screw 27, and projects forward hori zontally therefrom. Similarly, the shaft o comprises a short section or spindle 2S journa-led in a bearing 29 in the bracket 17 at the left 'side of the machine, and a section 30, connected at its rear end to said spindle by a universal ioint 31, and having its tor- The main driving shaft 16 isv j upward, the bell crank 32 will be y' vice versa. When the bell of devices will-apply y, Figs. l to 4 inclusive, the spool shaft 38 at shaft, and also which is secured icollar by a pin 50 which engages the lower' V5g the spool shaft.

Q a circular motion.

bell crank levers are connected together by a link 34 having a slot and pin connection 35 by which the length of the link may be adjusted. The arrangement is such that when the bell crank lever 24 is rocked to throw its arm.l 24,-carryingrthe shaft section 21, rocked `in the reversedirection, the arm 32, carrying the shaft section 30, moving downward, andv cranks'are rocked to theleft to their full extent,l as shown in Fig. 6, a bevel gear 36 upon the movable shaft section 2l engages a similar gear 37 I yupon a spool shaft 38 vertically arranged at `the right side of the machine and the sec tion of the shaft a is lowered, so that a bevel gear 39 upon said section is out of engagement with a bevel gear 40 upon a vertical spool shaft 41 at the left side.y of the machine. When' the bell crank levers are `rocked in the opposite direction to their full extent, the gears 36 and 37 are disconnected and thegears 39 and 40 are engaged with one another. nThe bell crank levers are held i' -in either/o'their two positions by a spring 42 secured to the, top plate of the machine and 'having a roller 43 which bears upon a lshaped cam surface 44 at t-he upper end of the arm 24b of the bell crank 24.

IThe spool shafts 38 and v41 are arranged vertically at the centers of spool pockets 45 and`46 located in the forward art and at the sides of the top plate and having circular walls which are cast integral with the top plate. lVlechanisrn for reversing the direcvtion of movement of the ribbon, when the latter is unwound from the spool, is arg ranged within and adjacent to each spool pocket, and as these mechanisms are, in all respects, duplicates, a description of one set to both'. As shown in the right'of the machine is journaled in a A y'bearing 47 projecting upwardly from the` top plate in the center of the spool pocketthat is, from the bottom of the spool pocketand a collar 48, secured to the shaft, rests upon this bearing. rlhis collar supports the supports a ribbon spool 49, against rotation upon the piece 52 is pivoted to the upper flange of the'` spool, and the latter may be turned by placing the finger upon this piece. and giving it A spring 53, secured at Y vertical U-shaped one end to a lug within the pocket, bears against the base of the spool, as shown, in order tohold the spool which is uiiwinding frictionally to keep the ribbon 55 taut between the spools. Th'e ribbonpasses through guides 56 arranged in the the pockets, and through a ribbon. carrier or guide 57 adjacent to the printing point, as shown in Figs. l and 7, and hereinafter further referred to. The guides 56, as shown, consist in slots in the Walls of the pockets and sheet metal linings in the slots, each lining being connected to its pocket by fastening.

The spool cores 58 each have oneside 58a flat or cut away, as shown, and a lever 59 is pivoted to the lower side of the bottom flange of the spool. This lever, as shown in Figs. l and 3, has, at its free end, a downwardly inclined part 59a and a part 59 extending vertically upward through a slot 60 in the lower spool flange, said 'slot extending from the fiatface of the spool core toward the periphery of the flange. It willy be seen, from 'an inspection of F ig. l, that when the ribbon is Wound on the spool, the ribbon will bear uponthe projection 59" of the lever -59 and hold the latter against the flat face of. the core, as shown at the left in Fig. l. A spring 61 tends to force the lever away from the core, and when the ribbon is unwound from the spool, as shown .at the right in Fiom l, the lever moves away from the core until a stop 59C, upon the lever, engages the outer wall of a circular opening 62 in the lower spool flange. l

adj aceiit walls of an arm 54 and a screw or other' Within each spool vpocket is arranged a ring shaped cam lever 63 which encircles the bearing of the spool shaft and its internal diameter is"such that the downward projection or bearing piece 59a of the laterally movable lever 59 may turn with the spool, without engaging the cam lever, when the lever 59 is held against the spool core by the ribbon. lVhen'tlie ribbon is. unwound, however, the bearing piece 59a moves into position to bear upon 'and depress the cam lever. This cam lever is hinged at one side to a plate G4 supported upon studs 65 within the pocket, and having a stop projection 66 extending to the adjacent portion of the cam lever, as shown. The cam lever is normally pressed upwardly against this stop by a spring 67. lThe cam lever extends horizontally fora short distance from the hinge joint and then upwardly at both 'sides to form cam surfaces 63u. tion, shown in Fig. 2, the remaining clrcu'- lar portionI 63h, at the free end of the lever,

Zontal. The cam lever has an extension 63c at its forward end which extends downwardly and then rearwardly, as shown, to form a hook 63d. This hook is engaged by In its normal posiis inclined upward slightly from the horietages et the upper horizontal end 68 oi a vertically arranged latch 68 which ext-ends through a slot 69 in the bottom ri the spool pocket, and is provided with a pair of laterally extending arms (38h which are pvoted to a support or bracket 7() secured to the underside of the spool pocket. rlhis latch has a pin or pro jection 7l at its lower end which .extends laterally in the same direction as the arms, 1o and in the opposite direction to the part 68a of the latch. Each of the movable shaft sections 2l and 30 has a cam wheel `72 secured to it, adjacent to the latch, and these cam wheels have la series of cam surfaces 72a upon their peripheries for cooperating withA the pins 7l (see Figs. 2, 3 and 6). While the lever 59 is held against the spool core, the bearing portion of this lever will not engage the cam lever, and, therefore, the 2o parts will remain as shown in Fig. 2, the latch being held with its pin out of line with the cam wheel on the movable gear shaft. lvvhen the ribbon is unwound smclicient to release the cam lever 59 the free end of the latter.l moves outward, and the bearing piece or projection 59, with the continued rot-ation of the spool, rides up onto one ot' the surfaces 53a of the cam lever, thus depres. ig' said.v latter lever and allowing the latch to swing about its pivotal point until the pin 71 extends beneath the cam wheel, as shown in Fig. 3. It will be understood, of course, that the movable ear shaft is out of gear with the spool shatt upon which the spool which is unwinding is mounted, as shown in Fig. 3.' ln this figure the shaft section El is in its lowerposition with the Cain wheel 72 resting upon the in '71. The continued rotation of the sha 't section 2l 40 and cam wheel 72, while the earn lever is depressed, causes one tooth on the cam wheel to bear upon the pin 71 and thereby elevate the shaft section 2.1. This upward movement ot the shaft section 2l tilts the bell crank levers untiLthe roller 43 on the spring 42 passes over the center of the cam surface et on the bell crank lever 24, when the gear 36 on the shaft section 21 will be thrown into mesh with the gear 37 on the right hand spool shaft, and the gear on the shaft section 3() will be thrown out of engagement with the gear l0 on the left hand spool shaft, as shown in Fig. 6. The ribbon will then wind onto the spool at the right o'l2 the machine, and when the' ribbon has been entirely unwound from the spoolv at the lett et the machine, the same reversing action will be accomplished by the mechanism connected with the lett spool. Pznm mbmng mecLansm.-ln traveling from ene spool to the other the ribbon passes 'through theribbon carrier 57 whichy is adjustable vertically in front or" the platen bracket 73 having arms 73e top plate centrally or' the ma chine. The ribbon carrier is preferably of sheet metal, and, as shown in Figs. l and 5, has integral angular arms 57a and 57h at its upper and lower ends respectively, engaging guiding edgeson the bracket. These arms 57a and 57h are some distance apart and permit the carrier to slide freely on the bracket, without binding. The ribbon extends through an ular guides 57 atthe upper side edges'o and integral with the 75 carrier, and these guides are inclined forwardly in linewith the ribbon coming from the spools and 'joined to the carrier slide by round bendsor' corners'as shown in Figs.

l, 5 and 5, so that the ribbon is not re 50 quired to travel over any sharp edges on the carrier. Normally the ribbon is held b the. carrier below the printing line on the platen, so that all writing on the paper is visible. Means are provided for moving the carrier upward each time-a key is depressed,

to bring the ribbon to the printing line, and the movemento the carrier may be regulated so that/type impressions maybe made i from the upper or the lower half ot the J0 ribbon as desired 5 or the ribbon carrier may be held inoperative, in its normal position, below the printing point, while the keys are operated. By varying the throw of the carrier the upper and lower portions oit an ordinary ribbon may be used, or polychrome ribbons may be employed and the throw of the carrier adjusted to bring` diiierently colored zones or' the ribbon to the printing1 point, at will, for printing in different colors. in mimeograph work, where it is desirable to have the type strike directly against the mimeograph sheet, instead'ot1 against a ribbon, the mechanism is adjusted so that the ribbon carrier will remain inoperative, in it; normal position, with the ribbon below the printing point, while the keys are operated.

As shown in Figs. 7 to l2 inclisive, a ribbon vibratinr lower end o? the ribbon carrier '57 by a pin-and-slot connection, and it extends rearwardly therefrom beneath the top plate. rlhe rear end of this lever or vibrator is connected b a link 75 to an arm 76 which is 115 adjustabi f secured tLo a rock shaft 77. "the universal bar. 78 is connected by .arms 7S) to this rock shait, and the movement ot. the universal bar, therefore, communicates a vertical reciprocating motion through the arm Z6-and link 75 to the rear end of the lever or vibrator 74, each time a key is depressed. As shown in Fig. 8, the vibrator arm or lever 74 has a vertical slot 74EL near its rear, end, and perforations 74 and 74 125 arranged respectively atopposite sides ot said slot. The lever 74 extends through a vertical guide slot 3GB in a guide piece or1 braclre *30, and is held against lateral move- -ient .y the walls of said slot, although lever 74 is connected to the 110 gg ceases free to move vertically therein. 'Ihe guide piece or bracket 8O is, as shown, secured to the center of a bracket 81, of the top plate of the machine, and having arms 8l*L dependin at the sides of the guide 80. A l

guide ro or pin 82 extends between the arms 81a of the bracket and passes through the guide 80 and through the slot 74El in the lever 74. Above the lever, a similar guide rod or pin 83 is secured in the arms of the bracket 8l, and-upon these guide rods or pins is arranged a slide 8i having arms 84a and 84h at opposite sides of the guide 80. The arm 84a carries a fulcrum pin 85 adapted to the perforation 74C in the vibrator 74, and the arm 84;" carries a ulcrum pin 8G adapted to the perforation 74e in thelever 74. The slide 84 is movable upon the guide pins 89 and 83 transverselyv of the lever 74, and when moved in one direction the fulcrum pin 85 will enter the perforation 74, and when moved in the opposite direction the fulcrum pin 86 will enter the perforation 74th. The pins are of such length that when one pin is in enga-gement with the lever 74; the other pin will be out of engagement, and in the mid position of the slide both pins will be out of engagement with the lever. It Will be seen, therefore, that when the slide is in the mid position, with both fulcrum pins out of engagement with the lever, the rear end of the latter will move freely up and down when the universal bar is rocked by the operation of the keys, as indicated in dotted lines, Fig. 1Q, the slot 741.21 in the lever permitting such movement, while the guide pin 82, extending through said slot, prevents endwise movement of the lever. In this mid position ci the slide, the forward end of the lever turns pivotally about its connection with thc ribbon carrier, and the latter remains in its normal position, shown in Fig. 7, with the ribbon below the printing point. When the slide is moved so that the pin 85 engages and becomes the fulerum point for t-he lever, the latter will rock about this point as a center, giving the ribbon a suiiicient upward movement at each depression of the keys to bring the upper half of the ribbon opposite 'the printing point, as shown in dotted lines in Fig. ll. When thefslide is moved in the opposite direction, and the ,ffulcrnm pin 8G enters the opening 74] in the lever, it will be seen that the forward end of the lever will be given a greater movement, at each depression of the keys, bringing the lower half of the ribbon to the printing point.

In order to conveniently' operate the slide and hold it stationary in its several positions, I provide a switch consisting of a bar v87 arranged to slide, as shown, in openings in the bracket arms 73a. rlhis rod is provided with linger pieces 87 at its ends, by

.which it may be moved in either direction,

and it has a series of notches 87h corresponding in number to the number of posit-ions of the fulcrum carryingslide 84. A holding spring S9 is adapted to engage these notches and hold the rod in any of its several positions. A lever 90 secured by a pivot screw 91 to the under side of the top plate, has a. fork 9Ol at its forward end engaging a pin 92 on the bar 87, and said lever has a fork 90b at its rear end engaging a pin 93 upon the fulcrum slide 84, the arrangement being such that a'movemcnt of the bar 87 in one direction will cause the movement of the slide in the opposite direction. It will be apparent that by simply adjusting the rod 87 to the ldesired position, the leverage on the vibrator bar or arm 74 may be changed, at will, .in the manner indica-ted, or the arm 74 may be rendered inoperative as a lever,

yand the throw of the ribbon carrier may be thus varied or stopped.
