To aZ'Z whom it may concern/:

Be it known that we, RICHARD M. Hot: and

STEPHEN D. TUCKER, of the city, county, and

State of NewYork, have invented certain Inn provements .in Printing-ltlachines, m" which the following is a specification.

This invention consists, mainly, in amechanism whereby sheets are successively carried onward for delivery, with which co-o'perate automaticallyanoved switches, that operate to direct alternate sheets conveyed within their range of action into separate conducting-chair nels. said vibrating switches, of cylinders constructed of separate pulleys placed on a common shaft. It includes a type cylinder provided with longitudinal and transverse grooves, in which slide clamp-blocks, which are secured to counter clamp-blocks that engage withand hold the prilitingplates; and said invention further comprehends combinations of devices, as will be particularly hereinafter set forth and claimed. Figure 1 represents one side-elevation of the- Inachinekmd Fig. 2 the opposite side elevation of the same. Fig. 3 represents a longitudinal vertical section taken in planes parallel with the plane of Figs. 1 and 2, andshowing, in side elevation, the meeh anism beyond the feeding-in cylinder. Fig. 4 represents a plan view of one of the type-cylinders with the stereo: type'plates secured to it; and Fig. 5 is a like view with the stereotype-plates removed.

Similar letters of reference indicate like.

parts in the several figures in which they oc' cur.

We will first describe the construction and operation of the first part of said invention.

In Figs. 1, 2, and 3 of the drawings, 20 and 30 represent inclined feeding-tables, on which the sheets of paper are to be placed, and from which they aresuccessively fed by operatives to the feeding-in cylinder F.

and that of the table 30 just below, the feeding-in cylinder F. Thesetables are to. be provided with the usual means'to enable theoper- It also embraces the combination, with The lower end" of the upperlieeding-table, 20, is just above,

and carry forward the sheets; and it receives motion from the main shaft Si by the train of cog-wheels 32 33 34.

It is providedin the usual-manner with gripingfiugers 5, projectingi'ronra shaft, 6, mounted in a recess made in the cylinder F for that purpose, and one end of the said griper-shaft projects beyond one end of said cylinder, and is provided with a rockarm and crank-pin, 7, which rock-arm, actuated bynnechanisms mounted in the side frame, rocks said shaft and turns the gripingfingers in one direction to gripe the edge of 'a sheet 01' paper againstthe surface of the cy1-' inder, and then in the. opposite directiomto liberate the sheet, .These griper--operating mechanisms are in their separate elements of the usualand well-known construction heretoi'ore used; but that part of them for closing the fingers is duplicated, the same consisting of two revolving-cams,l8 9','whose p'iniops17- 18 are geared to ether and driven by an Inter that is fast on the shaft ol' mediate pinion, the cylinder Egyvhich camsco-operatej'with fixed cams 26 2'7, fastened to the side'l'frame. One set or part of this gri'per mechanism'is arranged above and the other below the shaft of the feeding-in cylinder Fone settof-o perate the fingers for taking thesheets-from one and the other for'etaking the sheets from the other feedingtable. Said pinions are opened to release the sheets to be carried onto the impressioncylinder I by a fixed stud, 70.-

he machine being in operation, a sheet of pa er on the feeding-table 20 is moved down by the operative to the proper gage, so that its lower edge will be in the required position to be griped by the fingers 5 of the feeding-in cylinder.

carried around and presented to the impression-cylinder I, which is on thes'liaft'ot the I cog-wheel 33, and receives motion from the main shaft by the cogwheel 32. This cylinder is provided, as in the usual manner, with gripi'ng-fingers 10, operated in the usual manner, which gripe the same edge of the sheet as it is liberatedby the griping-fingers of they feeding-in cylinder.

The sheet of paper thus transferred is carried around with the cylinder I and presented tothe type-cylinder T, and receives the required im;

So soon as it is griped the sheet is ferred.
