had ition to these line spacing devices provision is made for turning the platen 36 automatically during leftward movements of, the main carriage by means which coma shouldered prise a roller 175 pivoted on screw 176 secured to a crank arm 157 near operate with a cam 177 carried by a slide mounted adjustably' on a toothed bar 179 secured to lugs 4 on the posts 4, the bar 179 extendin transversely .of the machine. The upper e ge of the bar 179 is formed at letter space intervals with 'teeth 180 and."

these teeth cooperate with a tooth 181'on the slide or cam member 178. The slide is formed with 'lips or troughs atits top and bottom so that it partly embraces the bar 179 and cannot be detached therefrom except by being slid ofi it .endwise. The tooth- 181 is maintained in engagement with the teeth 180 by a bowed spring 182 carried by counter to its sprin 159, and the pawl 164 will engage with t e ratchet wheel 149 to ,-;;turn the platen, as when the handle 156 is arrange so the slide and cooperative with the bottom face of said bar 179. The construction'is such that by pressing upward against the slide its spring may be overcome and its tooth disengaged, and it {m'aythen he slid to desired positions along e bar Jso as to vary the location of the camiand its consequent point or time of co action with the roll 175,.

A scale: on the bar-179 is preferably pro vided facilitate adjustment of the parts carrie thereby. When during leftward movements of the cariia'ge the roll 17 con.-

tacts with the cam 177 it will ride" up said ca'm until arrested by a dwell or stop por-" tion 177 in whicb ithe left endof the cam terminates. As a consequence the crank arm 157carrying-the roll. will swing on its axis and the shaft 154 will be forced to tur'n operated. The parts are proportioned and into-the ratchet-wheel by "the stop 174 to arrest the parts the roll 175 will be in engagement withthe stop 177, and since the rol can swingno farther about the shaft 154 it will act in cooperation with the end on part 177 as a stop to limit the leftward movement of the mam carriage and also to prevent disconnection of the automatically e platen 36 connected thereto. The turn- I "depending from the base plate 183 an outer end. Said roller is adapted to co gular plates 231 thatwhen the pawl-is jammed as shown in the arm 157 is releasably connected withthe shaft 154 so that the roller 175 may be ren:

dered inoperative, if desired. 7 I

The sub-carriage which is supported for relative movement on the main comprises, as appears from Fig. 2, plate183'having upturnedend rtions 183. Said'sub-carriage underlies e cross bar of the main carriage, said cross bar being formed with a groove 184 providing a track-way with which the base plate 183 is connected by roller bearing devices 185. The sub-carriage is provided with a In 193 am by a cord 193 to aspring drum194 which' constantly impels the subcai'riage toward the right. To hold the subcarriage againstthe pull of'its spring drum 194 and set in propel-"relationship with the main carriage, detent fievices are provided comprising a rack bar 198 on the main cars riage and a cooperative releasable pawl or detent 200 pivoted at 201 on the sub-ear.-

gers 225 that are mounted on arms 227 which are'fixed to a sleeve on hollow rock shaft 229. The ends of said shaft receive bushings 230 which bear in openings-in an- 183'. The arms 227 alsoprovide bearings for a shaft 232 which carries a feed roller 233 that projects rearward through slots in the deflector 224. The roller 233 cooperates secured to the base plate with a larger or main feed or pressure roller located prising a sleeve 237 and a sheath 238. A13 will be understood from Fig.- 4 there is'fi xed in each end of the tube 237 by a'lltcrew 239 a flanged bushing 240, the flan" end whereof is outside the tube an abuts behind the deflector -224and co against'the associate end portion or bar 183' p of the sub-carriage. Extendin through the} ace'by screwsbushings 240 and secured p 239 are inner bushings of which th right;

over the face. of the platen 36, said paper feed -roller 237 238 comprising,

handone 242 is shown, the af or enlargement outside the end 20 are being indicated at 482 (Fig. 5). Said feed rollers 233 and 238 are maintained in spring pressed cooperation by draw springs 247, the springs tending constantly to turn the rocking frame comprising the shaft 229 and arms 227 toward the rear and maintain the feed rollersin engagement while the guide plate 224 on said rocking frame is. normally maintaind with its upper edge contiguous to the-platen36. The swinging of.said frame to control the deflector and feed rollers is performed by meansandin the manner set forthi n our said prior application, Serial No. 742,786 to which reference may be had for a fuller description of the sub-carriage and its paper feedingand controlling devices.

Means are also-provided operative from the main carriage for turningthe subcan riage feed roller 237, 238 to advance or retract at will the work sheetior sheets carried by the sub-carriagel Said means, as illustrated in Figs. 3, 4-and '12-to .14 comprise a squared shaft 265 which passesthrough said feed roller and bears in the end bars 26 and 27 of the main marriage. Said shaft is adapted to transmit motion to the feed roller throiigh the bushing 242 which, as

.shown in Fig. 4, has a depression 266 slightly larger in diameter than the greatest cross dimension of said shaft. -Said depression, however, extends only. partway through' the. bushing, leavlng a bottom or web 267 which is formed with a squared hole of slightly greater'dimensi'ons than the shaft 265 so that while the bushing may ,slide freely alongth e shaft'26d during endwise movements of the sub-carriage on the mam carriage,"yet in any of its positions rotary motion communicated to the shaft 265 will be transmittedthrough the bushing 242 to the roller 237,238, causing it-to turn and advance or retract the paper in'cooperation with the roller 233. portion of the shaft265 projects some dis-. tance beyond the" end bar'27 and is provided with a knurled fingerwheel 26.8 by .which the feed roller 237, 238 may be turnedback and forth for feeding and adjusting purposes; Arranged on the shaft 265 just out side the end bar 27 is a line spiking ratchet. wheel269 provided with a hub 270 which,

receive' a set fscrew27l by which the ratchet wheel fixed to'thesh'afti Cooperative with said ratchet wheelie apawl carrying memher or" lever2 72provided =with twov pawl 73 and 2 74 and also ,with a stop lug at 2 76 I edon' a. shouldered screw-.278 secured in thee its other end' anchored to-a'fpinj 281 onthe end washer 27 .8. isarranged on the depression 290.

The right-hand end 275) Said fpawl member is pivoted f n n armor lever 277 which. in turn H dbai'1j27f The arm 277. is. provided with a restoring'spring 279 having one of its. ends hooked over a pill 280' onsaid arm and the shouldered screw 278 between the arm 277 and the spring- 279, said spring 006perating with said washer to prev; displacement of the arm 277 rightward away from the end plate-27. Forward of'its ivot 276 the lever '272 is connected to the ower end of a link 282 which extends upward and is connected at itsupper end to a. crank arm.

2.83 fixed by a clamping nut 284 to vthe re-- duced rear end 285 of a rock shaft 286' that extends horizontally forward above the. end bar27 and terminates in a handle or finger piece 287 which extends angularly downward forward of the entire carriage structure and of the top plate. The rock shaft 286' bears at its rear end in a bracket 288 secured to the end bar 27 and also bears in a housing 289 fixed to said endbar near its front end. The housing is bored out at 290 to receive a pawl spring 291, one end of which is anchored to the'housing and the other end to a collar 292 rigid onthe rock shaft and bearing in the housing at the forward end of The springs 291 and 279'tend to maintain the line spacing de: vices thus described in the normal positions shown in Fig. 3. By swinging the line spacing handle or lever 2S7 toward the right theshaftj 286 is rocked and the crank arm ,5 M

283 swung upward, said crank arm acting on the link282 to swing the lever 272 on its pivot 276"ihdepend'ently of the arm ,277 to the" position. indicated in Fig. 12. This movement brings the finger 275 into contact -with the pin 280 and also, swings the pawl tooth 273 into engagement with theratchet wheel 269. During further turning of the lever 287tl1e upward pull of the.

Ink 282 5 will be transmitted through the lever 272g).

to the arm or lever 277, causing the latter movnig upward the lever 272 whose roletion'ship with its support will notvary during the first portion of the upward swing thereof. .As a result the pa wl tooth 27 3 will. cotiperate with the ratchet 269 -to turn the its to swing upward on its pivot 278, bodily feed roller 237, 238 a units distance asregnsa lateld by its .detent -devices-and'succeedmg i this movement thepawl tooth 274; which has been brought into;v engagement -withthe ratchet wheel will, duringthe continuance of the upward swing of 'the parts, turn-the ratchet wheel through another -units distance, the partsbeing arrested finally and the line spacing movement determined 'by .the engagement of the finger 275 with the ratchet wlieel as illustrated in 13.

Thus an operation of the line space lever 287, i I

communicates-a line spacing movement equal "to two units to the pa er, on the sub-carriage. It will also "nderstood thatsaid lever 287 is operative o retract the main the double function of communicating pro.
