xetented. July 24, 1906.

To all whmn it may concern:

Be it known that I, Moinusson J. BAR" NETT, a citizen of the United States, residing at San Francisco, in the county of Sen Frencisco and State of California, have invented certain new and useful lmproveinen s in Delivery Mechanism for Printing Presses, of which the following is a); specification.

My invention relates to an improved de livery mechanism for printing-pro"see, the object of my invention being to provide mechanism of this character which shall be simple and cheap in construction end. certain and effective in operation.

My invention, therefore, resides in the novel construction, combination, and arrangement of parts for the above ends, hereinafter hilly specified, and particularly pointed out in the claims.

In the accompanying drawings. Figure l an elevation (i the rear portion oi n printingress containing the delivery mechanism. ig. 2 is a. horizontal section. of the some. Fig. 3 is a long tudinal vertical section on the line- A A. of Fig. 1. Fig. 4 is it view similar to Fig. 3, showing the ports in ii diilerent pose tion.

Referring to the drawings, repress bed of a. printing-press, end Loo iznpr cylinder. Said cylinder has secured thereon. hollow trunnions 3, revolving in boxes 4, sliding on the f nine 5 oi" the press, ttllil is revolved by inf-ans of gear-wheels 6, engaging with rocks 7 on the bed 1 of the prim In addition, it longitudinal rno'wcin H ported to the cylinder by means or Slllttli gear-wheels 8, secured upon the trunnions, which mesh with reeks sccurod upon the frame of the printing-press. 'lhis pa rt oi the apparatus, however, forms no part of my present invention.

The paper to be rinted (shown at 10) is held tothe'cylindor y grippenlingers en'- gaging one edge of the paper, snid. lingers be. ing formed integral with a. gripywi=plste 12, having pins 1'3, which slide in holes in the thickened portion 14 of the wall of the cylin' der, the inner ends of said pins being rounded to be engaged by the czun-czirrying shaft 15, having cam-shaped portions 16 thereon. One endiof said shaft is supported. in one oi? the hollow trunnions of the cylinder and is pressed in a longitudinal direction therein by means of a spring] 7 in said trunnion adjusted by ascrew 18 screwed therein. The other end of the shaft is supported in the other hollow trunnion, and its end projects outwardly from said trunnion and is adapted in the iongitudinal movement oi the cylinder to engage a. cam 19, justeble in a beveled groove 20 by rneens of it screw 2-1, the flanged head 22 of which engages groove in said cam 19. When the projecting end of the cairn-shaft 15 reaches said earn 10, said cairn-shaft is pi ished immrd, thereby causing the cannslia ed portions 16 thereof to engage the roun ed ends of the pins 13 and move the grippenfingers outwardly, thereby releasing the edge of the paper which has been printed on. This takes place just at the time when'sziid edge comes over the upwzirdlyprojecting ends of separiitor-strips These stri s are secured to cross-bars 24; 25, of which t 1e bin 24mg its ends secured to sliding carriers 26, said-can 'rn being i'iornie-lly retracted by me ris of 'lhese springs pull do Wm ard as uYWillTl, and thus hold the carriers 26 seats. The gripper-plate is out out dge, as shown at 28, to {eceivethe l l the Iiiterstrips. .it the same time hat the edge oi the peper is released from I t :e grnnier-iingers andjs also brought over the ends of the sepztretor-strips the boxes 4 engage upward projections or lugs 29 on the carriers 26, "so that thenceforth said carriers more with, the bores, the ends of the separator-strips being in close proximity to the Clli 'lllllffiltillCG oi the cylinder. In the meantime the "revolutipn of. the cylinder causes the paper 'to travel do sun on the to of the sopmotor-strips, midwhen the cylinr or is arrested the/paper, being c uite "free at its rear edge, continues onward by its acquired Inoinentuin end over said strips into any ble receptacle. Upon. the return movement of the eylihder the carriers 26 re errcstod by stop-pins 30 on the frame.

The rear upper corner of the bed has at cylinder byincens oi verticel Wires which ex- 'teched thereto vulcanized. iiber 31, and when log tend close to the cylinder between horizontal upper and lower bars 32 33, secured. to and traveling with the slide-boxes 4.

In order to adjust the separator-strips, so as to engage the paper at different elevations, the nuts 34 are provided. i

I claim 1. In printing-press delivery mechanism, the combination of a traveling rotary cylinder, gripping mechanism holding the edge of the sheet to the cylinder, means forwitlidrawing said mechanism from said sheet and separating mechanism comprising a part into close proximity with which the part of the circumference of the cylinder carrying the edge of the sheet is brought simultaneously with the Withdrawal of the gripping mechanism, said separatin mechanism then moving bodily in front of t e cylinder with the same direction and velocity, substantially as de scribed.

2. In printing-press delivery mechanism, the combination of a traveling rotary cylinder, gripping mechanism holding the edge of the sheet to the cylinder, means for withdrawing said mechanism from said sheet and sepa rating mechanism. comprising a part into close proximity with which the part of the circumference of the cylinder carrying the edge of the sheet is brought simultaneously with the withdrawal of the gripping mechanism, said separating mechanism then moving bodily in front of the cylinder in the same direction therewith, substantially as described.

3. In arinting-press delivery mechanism, the com ination of the cylinder, means for holding an edge of the sheet to the cylinder,

, separator strips, a movable cross bar to ich said separator-strips are secured, car- Here for said bar, s rings for said carriers, and means moving ongitudmally with the senses impression cylinder for engaging said care riers to move said bar against the action of said springs, substantially as described.

4. In rintingpress delivery mechanism, the comliination of a frame, boxes sliding thereon, an impression-cylinder having trunnions revolving in said boxes, a grip er holding the edge of the sheet to the cylin er, separator-strips, a movable cross-bar to which said strips are secured, carriers for said movable bar, springs retracting said carriers, and projections on the boxes enga ing said carriers to move them against sai springs, substantially as described. 1

5. In printing-press delivery mechanism, the combination of a cylinder, grip ing mechanism for holding the edge of the s set to the cylinder, separating mechanism adapted to engage the edge of the sheet at a redetermined point in the path of the cylin er means for withdrawing said gripping mechanism to release the edge of the sheet and means act ing simultaneously with said latter means for im arting longitudinal motion with the cylin or to the separating mechanism, substantially as described.

6. 1n printing-press delivery mechanism, the combination of a cylinder, means for delivering the sheets from the cylinder comprising means for engaging the edge of the sheet and a chute for directing the movement of the sheet, and a bed arranged to impinge uponsaid chute to agitate the same to shake the sheets down, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing Wit- IlElSSBS.
