:messia Be it known that LIRVING F.-N1nns,al citizen yof the United?y States,- residing' at Plainfield,vcountyofllnion, and 'State of. New Jersey, have invented certain. new and:

- useful Improvements in 'Delivery Mecha nisms, fully-described andrep'resented inthe following specification and theu accompany` ing drawings, forming a part ofl the same.

rlhis inventionrelates to'jcertain improve n ythe,grlpperson the impression cylinder.

parts, improvements rand vcomloinations as will be hereinafter fully described and their speciicallly pointed out.

Referring to the accompanying drawings FigureV 1 represents the'fside: elevation of the main elements of apnintingnpress rto.

- Machines embodying the invention` will include `a printing coupley onemember at` least of which is acylinder. yInfthe y'particular machine'selected'tofillustrate the inf vention which, is of the stop cylinder type,`

The sheets aredeliveredg to the cylinder, in the particular'machine illustrated, from a feed-board"illustratedat'* 13.? The flat delivery mechanismemployedy in Ina-rn chines embodyingtheinvention will usually be of the fly type. The fly is indicated vat 14 and delivers the sheets flat to azt-able, indicated at 15. The/shaft of theily is provided Wlth a toothed segment 16 Which is operated in an robvious manner from abent segment lever 17 through connections ivhich it is unnecessary' to describe.` r

Pawnee@ Aug10s 1915i; ApplicatiaanieaMay 2,1912, serialnce'eesa this transferring mechanism may be varied," f 1n the construction illustrated, it' includesr the usual delivery cylinder 18 providedwith grippers,` asy usual, which take the sheets from In the particular, construction shown .the

Y sheetsare delivered by the cylinder 181`to1a conveyer Winch/comprises' .:(seek Fig. 2) a pairof horizontally disposed endless chains 19;L These endless chains areV shown-as mountedon four sprocket vvheelsiZO, 21, kthe Wheels 20 being mounted on a shaft 22 and the Wheels 21 on a shaft 23,y these Vshafts being suitably supportedin bearings arrangedy yunderneat-li the feed-board- The shaft 22 is driven from they cylinder 10 by meansfof ya gear 50k on cylinder 10 meshing With a gear 51 on the delivery cylinder 18, vWhich gear in turn meshes with a gear carried on the shaft 22. The 'chains' supporty a cross' shaft QA anda cross rod 25, theshaftbeing mounted and.r theI rod socketed `in blocks 25 carried by the chains. The shaft supports a" .pair of gripper ng'ers. 27 which coperate with abutments 28 mounted on the rodQ; The gripper shaft is provided With 1a torsion spring :29vvhich yserves to; rockqfthe shaft and hold the grippers closed, the'shaft being rockedto open the 4grippers by an arm' 3() This arm 30 is provided with an offset roller 31 ,fvvhich at the proper time, that is to say, when the grippers are to be opened, strikesqan `anchored arm positioned on the. shaft` 22 before referred to. This armnot onlyopens the grippersQf to release thesheetfas" Will befhereinafter referred to, but also causes they grippers` tok remain open, so that .they take the sheetfrom the grippers 33 on the delivery cylinder, these grippers" being of the It will be understoodl that this, delivery cylinder 18is of the usual skeleton-` typ'e, thatis, it is made ,up ofl'disks' which* arepo'sitioned yso. as to bear ony the'sheet at its center and margins only. y The transferring mechanism, in the par-k ticular machine illustrated, includes a sheet c carrier which, as illustrated,y comprises a pair of tapes 3e arranged to run in a direcy tion opposite to the run of the chains 19.

VVhilekthis may be eiected by any desired means, in the Yparticular Vconstruction illustrated, Vthe shaft 22 Yhas a-'pair of`Y looseV pulleys mounted thereon over which the tapes run, the tapes also running over apair of pulleys 36 whichare fasten the shafti23.

e This shaft 23 maybe driven'in any suitable manner-.f Asshowm'it is provided with a sprocket wheel 37 over which runs a chain 3S, this chain'runningover a sprocket wheel 39. This sprocket'wheel vis connected to a gear 40 meshing with a gear 41, vthis being one ofthe main gears ofthe machine. It

Vwill be observed that thetapes are .so located that the upper runof' the chains overlies the tapes. Stationary guides 42 are or may be provided to insure correct travel of thev i chains. Y

rlhe operationr ofthemechanism willfbe clear from the ldescription before given.-

Thesheets are talren fromV the usual grippers Y on theimpres'sion `cylinder by the grippers on the delivery Cylinder 1S and by them de-Vv veyer.` The sheet is forwarded by theron-V veyer, the grippers of whichhold it by' its forward edge. After the grippers have coin- K- pleted their movement away frointhe cylinder 18 and during the time they are moving toward it, the lower .edge and under side of the sheet is dragging across the carrier tapes, but as the freshlyprinted surfaceof thesheetis uppermost, the sheet is not blurred,r Ars thefgrippers are completing their movement toward `thecylinder 18, they are opened andthe sheetfdrops onto the car- Vio - i 'Y following' sheet.
