To all whom t may concern u Be itlinown that I, lVAL'rER SCOTT, a citizen of the AUnited States, and a resident. of Plainfield, in the county of Union' and State of New Jersey, have invented certain new and'nseful Iinprovei'nentsfin Printing- Presses., ofwhich the following is a speci'li cation; y

My inventi'oiirel'ates generally toprinting presses, and hasmoreparticular reference to the means for cont-rolling the sheets in a two revolution rotary' printing machine, and. to the general arrangement 'of the parts and combination oit elements as will more fully hereinafter appear.

In its general arrangement, the invention contemplates a structure embodying a two revolution impression cylinder,a two revoln-v tion plate. cylinder, and a two revolution .collecting cylinder.

."he use of a two revolution impression cylinder or a cylinder making two revolutions 'to each sheet printedallo'ws the sheet c. to be deliveredin -`front ot the said impression cylinder. By the eni'iloyment of a two revolution plate cylinder adjacentto the cially when a. high grade of work is to be'\ done. I thereforelind it advantageous to employ a collect-ing cylinder making two or more revolutions to. each sheet printed-so as to deliver a pack of sheets of two or more to the tlv or other delivery means at a time, thereby venablii'ig the said fly tobe operated v at one-half the speed ofthe re'stof the machine, or in other proportions if Vtheelelnents' are dill'crently 'arranged and timed. The parts are made adynstable 'so that one sheet at a time can be transferred fro'mthe collect-A .ing vcylinder to `the ily it desired.l Av still fnrtheradrantage of a two revolution col lecting cylinder resides in lthe fact that the.

` lirst lsheet kwill pass around the' cylinder a cert-ain extent before the'- printed side' twice with the printed A'side ont in Contact with the'at.mospliere,thns drying the nik to comes in 'contact'with or meets the second sheet coming from the impression cylinder.

Ymachine embodying my' invention'.

This also enables the delivery mechanism to be run at a slower speed than when deliver'- ing one sheet at a time, which is of'great'advantage. in -rotary machines where high speed is attained. In the present instance where the" collecting cylinder deliversA two 'sheets ata' time, to

the iyor other delivery mechanism,fthe said collecting cylinder may Ibe described as a" long and a short pat-11'; that is a long path, namely, two revolutions `for the first sheet, and short path for the second' sheet. tly or other delivery .mechanism` is further made adjustable to operatelat aspeed corresponding to the number of revolutions which the collecting cylinder makes before delivering the sheets tothe fly, or to operate at variably predetermined intervals corre-` sponding tothe frequency of delivery of the sheets. l

`Other `improvements will --appear as the' specification proceeds.

In" the accompanying drawing, I haveshown myv invention embodied' in a suitable form, which, however, is siiscepti'bleof being changed materially, without-departing from the spirit ol the invention'. i

l. are marginal tapes on the upper surface of the cylinder D contactinfr with the margin of the printed sheets. Tzh'ese, however, may be omitted, or other means. used instead., f

The sheets are fed down on top of the feed boaid K by suitable'ineans, either from a roll ont into sheets from ay pile of any ot' the well known sheet feeders, or they may ,he ftd byh'and in the usual way. When the sheet reaches the impression cylinder, the gvippeis b1 will receive the said sheet and carry it' around the impression cylinder receiving an imprint while passing between the cylinders'B and C.` lVhen it reaches the upper side of the cylinderlB, after havreleased by the grippers 721and the throwoff. lingers 2'# raise the front edge of the sheet and place it upon the guides N. The sheet in passing over the guides N is slit by the slitter, itldesired,.and then passes on 'the upper edge of the cylinder D, where it is seized by the rrippers d1 which are at this moment operated by the cani cl3.

-When it is desired to collect, as is shown in the drawings, two sheets on the cylinder D before transferring them to the Hy, the lever Z5 is shifted down so that the roll Z comes in contactwith the cam (/T whereby the fly will operate once to every four revolutionsof the cylinder D, and the holt .2; is removed, allowing the cam Z4 to be operout of thc way every other time, so that the grippers all arelno-topened, but remain closed carrying r the sheet around with the cylinder a second timefan'd. being opened' to receive another .sheet bythe cani derand then opened by the cam dt thereby delivering the two sheets to getlier. j is' separated 'Vhen it is desired ,to deliver one sheet at 115 a time, the saiid sheet, after being seized b v the grippers di, iscarried' along to'the point of the sheet guide P Where it is released by thc said grippers all which 'latter are operatedby -the cani d4. In this instance, the cani bf lis all'owednto remain stationary by fastening the lever connecting it with the rotating .canig on`the framework by means ci' the bolt w. Likewise, incthis instance, the lever l5 has been shifted toa posxtionby the means 125 hereinbefore described, where the friction roll 7G will he in contact with. the cani g on the shaft G, wher'eby the-fly will operate once to 'every twogrevolutions of the cyltimes v than vthe collecting cylinder. The 'fly i, lIt is .obvious that by changing tne gears on the cam shafts, any number of sheets can be" collected by the cylinder D lbefore delivering theni'to the fly L,and the 4.iy can be adjusted to operate at a. spee-d 'corre-- sponding tothe speed of the said cam shafts,

ora variably predetermined less number of delivers the sheets to the. table' Q in thel usual manner. It will .beobse'rved that the printed sheetsV do not come in contact with their printed surface with anything unless the marginal tapes above the cylinder D 'are used, until they are delivered. Of course the cylinderD could be the last of the number of cylinders transferring the sheets from the impression cylinder.
