Original application filed January 17, 1901, Serial No. 43.599. Divided and this application filed July 12, 1901. Renewed July17, 1902. SerialNo. 115,985. (No model.)

To all whom it may concern: I I with each other at theirinner end. As shown Be itknown that I, JASON O. LOTTERHAND, in Fig. 3, each half consists of a rock-shaft a citizen of the United States, residing in the 174, mounted near the opposite ends of its city of New York, county of New York, and straight horizontal *portion in bearings 175 State ofNewYork,haveinvented certain new upon the framework-above the platen-roll and usefulImprovementsin TypeJVi-iters, of and having its inner end .176 bent at an anwhich the followingis adescription, reference gle of about forty-five degrees to its straight being had to the accompanying drawings, horizontal portion.

It results from this construcacross the machine through the guide-loops tion that whenever a type-key is depressed 4-3 of the vibrating -ribbon-throw,-by which the and the bail 151 thereby rocked thelinks180 ribbon is swung to and from the printingwill pull forward'upon the upper ends of'the line. The ribbon-throw is composed of two crank-arms 181and rock the shafts'174 in a like halves located on opposite sides of the direction to carry the ribbonover the machine beneath the ribbon-spools and eX- printing-point, and when the operatedkeyis' 5o tending inward therefrom, but not connected released and the bail 151 returned to normal 10 position by the spring 153 the ribbon-throw will be swung forward and the ribbon withdrawn from the printing-point. The arrangement of the ribbon and the character of the ribbon-throw described obviate the necessity for any sharp turns in the path of the ribbon, and thereby reduce the friction and wear upon its edges to the minimum,while affording an easy swinging movement of the ribbon to and from the printing-line.

Each of the ribbon-spools 172 has secured to its forward side by studs 1S2, Figs. 7 and 8, a ratchet-toothed ring 183, against whose smooth inner edge rests and travels a frictionroller 184,carried by the upper end of a springpressed arm 185, whose purpose is to afford sufiicient resistance to the turning of the ribbon-spools to preserve the proper tension upon the ribbon. Engaging the outer side of the ratchet 183 is a spring-pressed actuating-pawl 186, pivoted at its lower end to a verticallyreciprocating slide 187, guided near its lower end in a slot in a horizontal plate 188, Fig. 5, and provided near its middle with a rightangular bend and at its upper end with a vertical slot, through which passes a screw 189, entering the framework and serving to guide the upper end of the slide 187, Figs. 7 and 8. A spring-pressed retaining-pawl 190, pivotally supported at its inner end, engages the top of the ratchet 183 to prevent backward movement of the ratchet and spool while the pawl is engaged with the ratchet and at its outer end is bent to overlie the upper end of the vertically-reciprocating slide 187.

As will he understood from the foregoing description,when the slide 187 is reciprocated, with the parts in the position shown in Fig. 7, the pawl 186 will turn the ratchet 183 and spool 171 step by step and draw the ribbon across the machine from the spool 172 and wind it upon the spool 171, the pawls 186 and 190 which cooperate with the ratchet of the opposite ribbon-spool 172 being at such time disengaged from said ratchet, as presently explained. As shown in Fig. 7, the upper end of the pawl 186 is inclinedor beveled in such a way that when the slide 1.87 is lifted to its extreme limit of movementthe contact of the beveled upper end of the pawl with the screw 189 will force the pawl outward and disengageits tooth from the ratchet, as shown in Fig. 8, and the upper end of the slide will at such timelikewise lift the outer end of the pawl 190 and disengage its tooth from the ratchet. By lifting the slide 187 to and maintaining it in this position, therefore, both pawls will be held out of engagement with the ratchet and the spool be left free to be turned backward to unwind the ribbon therefrom. Now the actuating devices above described are exactly alike for both of the ribbon-spools, and means is provided for constantly maintaining one or the other of the slides 187 in elevated position, with the pawls disengaged from the ratchet of the correright-hand spool in Fig. 2 and as shown of the left-hand spool in Fig. 8, while the opposite slide 187 is held in its lower and operative position, as in the case of the left-hand spool in Figs. 2 and 7. To this end each slide 187 is provided upon its forward side with a stud 191, which studs cooperate with levers 192 and 193 at the opposite sides of the machine, Figs. 4 and 5. The forward ends of these levers 192 193 are loosely connected to the rearWardly-bent opposite ends of acurved lever 19-t, fulcrnmed at its middle upon a plate 195, secured to and depending from the forward side of the top plate of the framework, Figs. 5 and 6. WVhen the lever 194 is rocked upon its fulcrum so as to throw its right-hand end downward, as in Fig. 6, the front end of the lever 192 will be carried downward with it and the rear end of said lever 192 will lift the slide 187, associated with the ribbon-spool 171 at the right side of the machine, as shown in Fig. 5, and the pawls cooperating with the ratchet of such spool will be held out of engagement with said ratchet and the spool left free to be turned backward, while the opposite or left-hand end of the lever 191, being in elevated position, will hold the front end of the lever 193 elevated and its rear end depressed, as in Fig. 4, so that the slide 187 at the opposite side of the machine will be left in its lower and operative position.

For the purpose of reversing the position of the levers 192 and 193 to change the direction of movement of the ribbon I journal a short rock-shaft 195 in the right-hand side plate of the machine, Fig. 5, and secure to its outer end a suitable crank or handle 196, Fig. 6, by which it may be rocked backward and forward, and to its inner end a plate 197, provided with a slot eccentric tothe shaft 195 and engaging a stud 198 upon the lever 192. By turning the rock-shaft 195 rearward-until the stud 198 upon the lever 192 engages the opposite end of the slot in the plate 197 the forward end of the lever 192 will be thrown upward and its rear end downward, thereby releasing the slide 187 and at the same time rocking the lever 194 and causing its lefthand end to depress the front end of the lever 193, Fig. 4, and lift the slide 187 shown in that figure to elevated position and disengage the pawls from the ratchet of the lefthand ribbon-spool. A coiled spring 199, secured at its lower end to an inwardly-projecting stud upon the side frame of the machine and at its upper end to astud upon the plate 197 at the middle of its upper edge, serves to hold the plate 197, and consequently the levers operated by said plate, in their opposite positions.

The slides 187 are reciprocated to turn their rear ends of a pair of side arms 47, pivoted to the side frames of the machine at their, front. ends at 48.

One of said side arms 47 hasin. the present instance a depending extension at its front end, to which is con nected,

a coiled spring 51, which serves to yieldingly hold the universal rod 46 in its normal position, Figs. 4 and 5-, and return it thereto after having been depressed by a. type-key. The levers 200 and 201 are provided atv their rear ends with in \vardly-projeeti ng studs 202, 5

which underlie the lower ends of the slides 187 at the opposite sides of the machine, and whenthese levers are rocked and their rear ends thrown upward at each operation of the machine by the depression of the universal left-hand side of the machine will be reciprocated by the lever 201, Fig. 4, while the lever 200 at the right side of the machine, Fig. 5, will play idly up and down, since its cooperating slide 187 is held in elevated position by the lever 192. In Fig. 2 the reverse adjustment of the parts is shown, the righthand slide in that figure being maintained in elevated position and the opposite slide being left in operative position.

The springs 203, connected to the lower ends of the pawls 186, serve the double function of pressing said pawls into engagement with the ratchets of the ribbon-spools and of yieldingly holding the slides 187 in and returning them to their lower positions.

I do not claim herein any features shown and claimed in my application, Serial No. 43,599, filed January 17, 1901, and of which this is a division, nor in my other divisional applications, Serial No. 57,797, filed April 27, 1901, and Serial No. 68,697, filed July 17, 1901.
