Original application filed February 20, 1914, Serial No. 820,642. Divided and this application 1ed. .Tan-

uary 18, 1918.

To all whom t may concern:

Be it known that I, WILLIAM M. KELLY, a citizen of the United States, and residing at Jersey City, Hudson county, State of New Jersey, have invented certain new and useful improvements in Printing-Presses, of which the following is a specification.

This application which is a division of my application Ser. No. 820,042, filed February 20, 1914, relates to printing/presses and more particularly to the inking mechanism thereof. l

The objects of the invention are to provide an arrangement of the parts of the press whereby the members over and covering the inking rolls and mechanism may be raised to inspect the inking mechanism without in any way disturbing the operative connection of said members; to provide a novel mechanism for regulating the flow of the ink from the fountain; to provide a novel mechanism for varying the angular movement of the fountain roll to thereby control the ink feed; to provide a means for supporting the fupper rolls of the inking mechanism so that they can be raised to permit inspection of Iall the rollers; to provide a4 mechansim for adjusting the eX- tent of vibration of the ink transferring rolls; to provide means for adjusting the bottom ink rollers in two directions, and generally to improve the construction and arrangement of the inking. mechanism of the press.

Referring to the drawings, 4() represents the frame or base casting of the press and this frame has secured thereon the side ways 41 and 42 for the reciprocatingbed 43. The 85 ways 41 and 42 are provided with tracks or rails 44, and the bed 43 is"`provided with tracks or rails 45 between which and the rails 44 are arranged the rollers 46. The frame 40 also'carries ways 47 which sup- 90 port the central part ofthe bed. The ways 47 are provided with tracks 48 similar to the tracks 44 and the bed is provided with tracks 49 which register with the tracks 48 and between which and the tracks 48 the 95 roller bearings 50 are arranged. From Fig. 3 it will be evident that the bed is supported along four lines throughout its length and beingmounted upon rollers will move freely to and fro.

The frame 40 carries, at the opposite ends thereof, pairs of cushioning cylinders 51 with which plungers 52, carried by the bed, cooperate to bring the bed to an easy stop 'the shaft 80 (Fig. 4

at the' ends of its strokes and aid in the reversal of the movements of the bed.

The bed is reciprocated by mechanism engaging the racks 59 and 73 (Fig. 3) on the bottom of the bed, the mechanism being driven from shaft 88 which may be rotated by any suitable means, such as the pulley 91. As this mechanism forms no part of the structure claimed it is not necessary to describe the same. A full description however will be found in the above mentioned application. The shaft 72 arranged parallel to shaft 88is rotated by means of the gear train 71, 84, 86 and 87 and 1n turn through the bevel ears 7 8 and 79 rotates which operates mechanism described hereafter.

Secured to the frame 40, on opposite sides thereof, are the upwardly projecting brackets 153 and 154, these. brackets supporting a feed board 155 and feed table 362 and auto- 'matic feeding mechanism A. Above the shaft 275 the brackets 153 and 154 have journaled therein a shaft 292, this shaft being driven from the shaft 275 by means of gear wheels 293 and 294 (Fig. 2). Arms 295 and 296 are pivotally supported on the shaft 292 and are normally arranged immediately above the side portions of the feed board 155, and are connected by cross-bars 297 and 298. These arms -carry retarding ingers, feeler lingers, side register mechanism, etc. and devices which coperate withv the feed board 155, all parts being actuated from the shaft 292, whereby the arms may be swung upward to the dotted line position shown at 358, Fig. 5, without disturbing any parts carried thereby. Likewise the feed board 155, which has the feed tapes, driven from shaft 270 which in turn is rotated by means of gear trains 271, 272 and 273 may be swung about shaft 270 to the position indicated in dotted lines at 361. Of course, the feed board can be swung to this raised position only after the frame comprising the arms 295 and 296 has been j raised. When raised, the arms engage and are supported by the pins 359, these pins being arran ed in lugs 360 on the brackets 153 and 154. n swinging the arms 295 and 296 to the inoperative position none of the mechanism carried thereby is disturbed, and when the arms are again swung down to the feed board the parts are in operative position.

The inking mechanism comprises an ink plate 386, secured to the type bed, and a set of inking rollers 387, 388, and 389 which engage the ink plate and convey the ink to the type on each reciprocation of the bed.

Secured to the opposite sides of the machine are ink fountain brackets 390 and 391 and oppositely arranged supporting bars 392 and 393 are supported on these brackets, and the brackets 98 and 99, (see Figs. 1, 2 and 5). The spindle of the inking roll 387 has its opposite ends supported in bearings 394, these bearings being provided with downwardly projecting Shanks 395 by means of which the bearings are supported in brackets -396 secured to the bars 392 and 393 (see Figs. 9 and 10). The brackets 396 are secured to the bars 393 by means of screws 397 and lips 398, the latter engaging the upper andlower sides of the bars and preventing the brackets from turning. From Fig. 7 it will be observed that the screw 397 is arranged in a slot in the bracket 396, the screw entering a threaded opening 397 (Fig. 5) 'in the vbar 393. This construction permits the brackets 396 to be adjusted longitudinally of the bars 393 and also permits the brackets to be' readily removed from the bars.

A side elevation of the brackets 399 which support the bearings for the inking roll 388 is shown in Fig. 8. The inking roll 389 is supported in a manner similar to the roll 387, except that the bracket 399 is non-adjustably secured to the bar 393 by screws arranged in the openings 400.

The brackets 396 and 399 have threaded openings in alinement with the recesses for the bearing shanks and in these recesses are arranged screws 401 having heads 402 below the brackets and notched on their upper surface as shown at 403 (s'ee Fig. 11). Arranged in suitable recesses in the brack` ets 396 and 399 are spring-pressed plungers 404 which are adapted to engage the recesses 403 and hold the screws'401 in anv adjusted position. From Fig. 9 it will bve evident that the elevation of the ends of the inking rolls may be readily adjusted by turning the screws 401.

The brackets 390 and 391 support a plate 405 which coperates with the roll 406 to form the ink fountain. The upper edge of the plate 405 carries a bar 407 which is secured to a plate by means of screws 408. A blade 409 is secured to a bar 407 and, as shown in Fig. 5, contacts with the roll 406. On the underside of the blade 409 is a plate 410, a portion of which, adjacent the roll 406, is provided with slits 411 which form independently adjustable'tongues 412. Each of the tongues 412 has in engagement with the lower side thereof the end of a screw 413 carried in a threaded opening in the plate 405. As will be clearly seen from Fig. 5, the pressure of the plate 409 against the roll 406 may be conveniently adjusted to vary the amount of ink fed along the different portions of the roll, by turning the screws 413.

The brackets 390 and 391 carry an oscillating shaft 414 on which are secured a pair of arms 415, and these arms carry in suitable bearings on their upper ends, a ductor roll 416. Exteriorly of the bracket 391 the shaft 414 carries an arm 417 to which is .pivoted the upper end oa rod 418. vThe lower end of thel rod 418 is adjustably secured in the slotted arm 419 by means of a clamping member 420. The arm 419 is carried by a short shaft 421 which is journaled in a bearing 422 secured to the frame 40, (see Figs. 4 and 17). The shaft 421 carries, within the frame 40, an. arm 423 having at its upper end a cam roller 424 which engages a face cam 4425 on the shaft 80, this cam causing the shaft 421 and the shaft 414 to be intermittently oscillated to swing the ductor roll 416 from a position in contact with the roll 406 to -a position in contact with a roll 426 in order to transfer ink to the latter roll from the former. The cam roll 424 is held in engagement with the cam 425 by means of a spring 424 having one end connected with the bracket 391 and the other end connected with the arm 419, (see Fig. 2).

The roll 426 and a companion roll 427 are carried in brackets 428 pivotallysuspended from the shaft 429. the roll 426 carries a gear 430 and the spindle of the roll 427 carries a gear 431 which meshes with a gear 432, the latter gear being supported on a stub shaft on the bracket 98 (see Fig. 1). rlhe shaft 429 carries an ink roller 433 which engages the rolls 426 and 427. rlhis shaft also carries a gear 434 which meshes with the gears 430 and 431. The gear 432 meshes with the gear 435 and the latter gear meshes with a gear 436, (see Figs. 1 and 3). The gears 435 and 436 are carried on stub shafts on the bracket 98' and the gear 436 is adapted to mesh with a rack 437 (see Fig. 3) on the bed'43 and be rotated thereby. The rotation of the gear 436 effects the rotation of the rollers 426 and 427, and the latter rollers contacting with the rollers 387,388 and 389 will cause the same to be rotated so that the lower surfaces thereof, which engage the ink plate and the type, will move in the saine direction as the bed. The rollers 426 and 427 are arranged to be vilrrated in an axial direction and for this purpose the spindles of these rolls are extended onthe left side of the press and each provided with a pair of spaced collars 438, as shown in F ig. 17. A lever 439 is pivotally mounted on bracket 440 as at 439 and carries on its upper end a pair of rollers 441 arranged between the collars 438. It will be seen that bv this construction the rollers 426 and 427 may be vibrated axially by oscillating the lever 439. For the purpose of oscillating the lever 439, the bracket 440 having pivotally mounted thereon at 442 a lever 442, and the lower end of this lever is pivotallyconnected with the eccentric rod 443, this eccentric rod being actuated by an eccentric 444 on the shaft 80 (see Fig. 4). The lever 442 is provided with a longitudi- 'lhe spindle of nal slot 445 Yin one side thereof, as shown in Fig. 18, and arranged in this slot is a roller 446 carried by a pin 447 which is adjustablvsecured in a slot 448 in the lever The pin 447 has an integral collar 450 which engages one side of the lever 439 and the portion of the pin on the opposite side of the lever 439 is threaded to receive a nut 451 by means of which the pin is secured in any desired position in the slot 448. fr? rom Figs. 2 and 17, it will be seen that the slot 448 is of sufficient length to permit the axis of the pin 447 to be in alinement with the pivotal su port of the lever 442, and when the pin 44 is in alinement with this pivotal support no oscillatory movement will be transmitted from the lever 442 to the lever 439. When the pin 447 is in the position shown in Fig. 17, however, the lever 439 will be oscillated by the lever 442 and extent of oscillation of the lever 439 may be varied by changing the relation of the pin 447 to the pivotal support of the lever 442.

The shaft 429 is journaled in arms 452 and 453 (Figs. 1 and 2) which are pivoted on the spindle 454 of the roll 406 and are connected together by means of a cross rod 455. Referring to Fig. 5, it will be seen that the arms 452 and 453 are adapted to be swung upwardly to the dotted position and when so swung carry with them the brackets 428 and the rolls 426 and 427. When these parts are swung 'to the dotted position, the inking rolls 387, 388 and 389 are accessible and may be readily removed.

ln order to feed the ink from the ink fountain, the roll 406 is intermittently rotated in the direction of the arrow shown in Fig. 5, and for this purpose the spindle 454 carries at the left side of the press a ratchet wheel 456, (see Figs. 2, 12 and 13). Loosely mounted on the spindle 454 is a lever 457 which carries a pivot 458 on which is mounted a pawl 459 adapted -to engage the teeth of the ratchet Wheel 456 and rotate the latter. The pawl 459 is normally pressed toward the ratchet Wheel by means of a spring 460 carried by the lever 457. The lever 457 also has pivoted .thereto al rod 461, the lower end of which is pivoted to an arm 462 on a shaft 463 which is supported in a bearing 464 on the frame 40. Within the frame 40, the shaft 463 carries an arm 465 having a cam roller 466 which engages a face cam 467 on the shaft 80 so that the shaft 463 will be oscillated on every rotation of the shaft 80. The roll'er 466 is held in engagement with the cam 467 by means of a spring 466 which has one end secured to the bracket 391 and the other end secured to the arm 462. Oscillation of the shaft 463 causes the lever 457 to be oscillated and the pawl 459 to intermittently `rotate the ratchet wheel 456 and the spindle 454. The degree of oscillation of the lever 457 is constant, and in order to vary the amount of rotation iven to the ratchet wh'eel.456 by this oscillatory movement of 5` the lever 457, there is loosely mounted on the spindle 454 a gear wheel 468 having teeth extending. around only a portion of its circumference and carrylng a plate 469 which extends into the plane of the ratchet 10 wheel 456 so that when the wheel 466 is rotated te a position to bring the` plate 469 between the point of the pawl 459 and the ratchet wheel, the pawl will be prevented from engaging the teeth of the ratchet wheel and thereby prevent it from rotating the latter. By adjusting the position of the plate 469 relative to the path of movement of the point of the pawl 459 any part of the movement of the pawl, from zero to the maximum, may be transmitted to the ratchet wheel and the spindle 454. In this way the rate at which ink is fed from the ink fountain may be regulated.

For the purpose of adjusting the gear 468 to vary the extent of rotation of the roll 406 there is arranged in mesh with the gear 468 a pinion 470 mounted on a shaft 471 journaled in the brackets 390 and 391. At the right side of the machine the shaft 471 carries a4 sector plate 472 having a handle 473 and provided on its inner side with a series of recesses 474 (see Figs. 12 and 15),y these recesses being adapted to receive the point of a latch pin 475 which is pressed against the plate 472 by means of a spring 476. The

end portions 477 and 478 of the plate 472 are adapted to engage the shaft 414 and thereby limit the movement of the sector plate.- It will be evident from this construction that by swinging the sector plate from the position shown in Fig. 12, the plate 469 will be carried into-the path of the point of the pawl 459, and when the end 47 8 of the plate 472 engages the shaft 414 the plate 469 will be in positionto prevent the pawl from actuating the ratchet wheel 456. The cam wheels 425 and 467 are so arranged that the roll 406 will be normally rotated when the ductor roll 416 is in engagement there- 50 with and therefore the ink will be transmitted from the roll 406 to'the roll 416.-

When the roll 406 is not rotated it will be evident that the ductor roll 416 will ynot carry ink to the roll 426. The ro1l`406 may also be rotated manuall by means of a hand wheel 479 onthe end o the spindle 454 (see Figs. 12 and 14). This hand wheel `was omitted from Fig. 2 in order to illustrate parts which would be concealed thereb Although a specific embodiment o the invention has been shown and described it is understood that the details thereof may be varied within the scope of the appended r claims without departing from the spirit of the invention.
