the motor is mounted upon the frame a carried by the column 0, The upper end of the column 0 1s screw threaded and provided with a lock-nut p, so that the frame 7% may be adjusted vertically on the column, to tighten the driving belt 9 connecting the pulley r on the motor with the driving pulley J.

0 represents the roll of paper and P is the paper straightening de ice to which the paper first passes, shown in detail in Fig. 18. From thence thejiaper passes to the paper tension device Q, shown in detail in F igs. 25 to 28 inclusive. The frames E and F are provided with the platens R having the tympan beds q, over which the paper passes in a straight line, the paper being indicated by the numeral 2. The form car riers S for the upper print sections are similar to the form carrier S for the under -print,section, and inking devices T are pro vided for the upper print sections, while a suitable inking device T is indicated in Fig. 1 for the under print section. The construction of the inking device '1" is substantially the same as the inking devices T, exceptthat theink is fed upwardly instead of downwardly. The upper portion of the frame F on unit C is provided with the offset paper device U having the unwinding roll 1" and the rewinding roll .9 for the offset paper if.

The paper is printed on the upper side by the form carriers S of the upper print sections and printed on the under side by the form carrier S of the under print section. The offset paper device is provided for protecting the printed paper as an impression is being taken in the under printsection. The chases u of the printing sections are transversely adjustable in their form carriers and the details of the devices for ad- '15 is shouldered at 3 and the driving pulley J and its bushing l turn loosely on the reduced portion. of the shaft. 'lurningwith the shaft K is a mutilated wheel 5 on the hub 6' of which slides the grooved sleeve 7. The sleeve 7 turns with the hub 6 by means of a feather. The wheel 5, as shown, is cut away at the points 8 in its periphery and friction stra s 9 and 10 are carried on the periphery o the Wheel. The strap 9 cooperates with the internal flange 11 on the pulley J, while the strap 10 cotiperates with the housing 12 connected to the frame of the unit A.

At the other side of the ratchet wheel is an arm 261 loose on the shaft and carrying on its hub a gear 262 meshing with the rack 263 on the rackbar 264 connected to the crank-pin 265 on the crank-disk 266 on the end of the powershaft 230. Pivoted between the

arms

260 and 261 is the pawl 267 adapted to engage the ratchet-wheel. 258 on the downward stroke of the rack-bar 264 and thus advances the fountain-roll step by step. The end of ]the shaft 257 is provided with a hand wheel 268 for turning the fountain-roll by hand. if desired.

The brayer-roll 269 is carried on the brayer-arms 270 secured to the brayer-shaft provided at one endwith a crank-arm 272 connected by therod 273 to the crank-pin 252 on the gear 234, whereby rotation of the shaft 230 and gear vibrates the brayerarms 270 and with them the brayerroll 269 between the inking-drum 231 and inking plate 99.

The crank-pin 265 on the crank-disk 266 for actuating the fountain-roll 253 is preferably radially adjustable in order to vary the throw ofthe rack-bar 264. As shown, the crank-pin 265 is carried on the sliding block 27 4, sliding in grooves 275 in the crank disk 266. A screw threaded rod 276 passes through the block 275 and is provided with a hand-wheel 277 dered end 278 having a nut 279.

The operative connections for the inking l B are upper print sections and unlt C is an The duetor-roller 247 is carried in the arms 248 connected to the transverse shaft 249' fountain-roll 253 and pressure-roll 246,.

at one end and a shoul-- head and inking device of unit O are sub 271 carried in hearings in the brackets 223 hearing 282. The shaft 280 is provided with fhe bevel gears 283 and 284 meshing with "the bevel gears144 and 154 respectivel The transverse shaft 153 carrying the bevel gear 154 of unit C- 18 provided with hearings in the frame F of the offset paper device.

Ofi'sef (Zem'ce.l3ehind the gear 154 of" unit C, is a gear 285011 shaft 153 from which power is taken for actuating the connections of the offset paper device. 1 The paper roll 7* from which the paper t is unwound and the paper roll .9 upon which the paper is wound are both supported in suitable bearings in the frame F. The paper passes from the roll 7' over the tension-roller 286, thence over the guide-roller 287, between'the chase and tympan bed, thence over the guide-roller 288, between the feed-drum 289 and pressure-roller 290, thence over the tensionroller 291 and thence to the winding roll .9.

, The tension-

rollers

286 and 291 are carried on arms and 293 pivoted to the upright 294 carried upon the frame F. A tension spring 295 connecting the short end 296 of one arm zwith the longer end of the other F arm, normally tends to elevate the outer ends of the tension arms and. apply tension to the paper t. v

The gear 297 meshes with the gear 285 and is provided with a crank-disk 298 having an adjustable crank pin 299 to which is connected the rack-bar 300 having the rack 301 meshing with the pinion 302 loose on the shaft 303 of the feed-drum 289. A collar 304 pinned to the shaft 303 holds the pinion 302 against, the sleeve" 305. The rack and pinion are provided with a suitable housing 306 open at one side to expose the'teeth 307 on the outer face of the pinion 302 which in effect forms a toothed clutch member adapted to coiiperate with the teeth 308 on the sliding sleeve 309, which forms the other .clutch member, said sleeve heing pinned to the shaft 303 by the pin 310, which is adapt ed to permit the slight longitudinal movement of the sleeve 309. lVhen said sleeve 309 is forced into engagement with the pinion 302, the npward stroke of the rack bar 300 will rotate the shaft 303 and feeddrum 289 in the proper direction to rewind the paper t. The

teeth

307 and 308 are so disposed and have the proper pitch to cause the pinion 302 to run idle on the return stroke of the rack-bar.

The gear 298 meshes with another gear 311 having a crank disk 312 provided with an adjustable crank-pin 313 connected by a connecting rod 314 with the arm 315 carrying a. pawl 316 coiiperating with the ratchetwheel 317 on the shaft 318. Connizted to the ratchet-wheel 317 is a disk 319 provided with a cam 320.cooperating with a pivoted lever 321 pivoted at 322 to the bracket 323. The outer end of said lever is adapted to bear upon the spring pressed pin 324 having a collar 325 beneath the cap 326 on the end of the sleeve 309. In the recess 327 in the sleeve 309 is a compression-spring 328 between the shoulder 329 and collar 325. The pin 324 extends loosely through the shoulder -329' and between saidshoulder and the end 330 of the shaft 303 is another compressionspring 331 which is weaker than the spring 328. The spring 328 normally forces the toe of the pm 324 outwardly beyond the cap 326' and when the cam 320 forces the outer end of the lever 321 inwardly, the pin 324 is carried inwardly against the pressure of the spring 328, thereby forcing the sleeve 309 longitudinally of the shaft 303 and overcoming the pressure of the spring 331, thus cushioning the engagement of the

teeth

307 and 308. The function of the light spring 331'is to return the sleeve 309 to its butermost position with the

teeth

307 and 308 of the clutch members disengaged. By'varying the throw of the crank-pin 299the amount of feed may be varied, and by varying the throw of the crank-pin 313 the rate of feed 'may be varied. Y

in order to drive the rewinding-roller s the crank-disk 312 is provided with the groove 332 for receiving the-belt 333 which also engages the grooved pulley 334 on the shaft The end of the rewinding roller shaft 5- is also provided with -a grooved pulley s which is frictionally driven by the same belt 333 which drives the grooved pul ley 334, thereby driving the rewinding roller 8 in the proper direction to rewind the paper. The unwinding roller r is preferably provided with a brake-disk 'r and the brakeshoe rv for regulating the unwinding of the paper. r

In Fig. 32 details of a device for automatically disconnecting any one of the units is shown 111 0358 any part of the mechanisn'i becomes 1annned, due to dropping of the type for instance. The gear 154 on transverse shaft 153 is mounted on a sleeve 340 splined to the shaft. Two shear sleeves 341' and 342 are set into the hub of the gear and the sleeve 340, and inclose a shear pin 343 of less st-rengththan the gear teeth, so that said pin 343 will shear oh? before the teeth will strip, thus disconnecting gear 154 from its sleeve and shaft. v
