improved sheet feeding and delivering devices for feeding sheets of'metal, wood, cardboard, or fabric to the printing mechanism of the machine and delivering them after the impressions have been received'thereon. The specific improvements will be readily understood from the following detailed description taken in connection with the accompanying drawings; in which bigure 1 is a broken plan view of the printing machine embodying the invention. Fig. 2 is a broken side elevation of the machine.

Fig. 3 is a cross section through the ma chine. I v

Fig. 4 is a detailed view illustrating the guiding mechanism for feeding the work between the printing cylinders after it has been moved toward the printing point by the feeding mechanism. 1 y

In the embodiment of the invention illustrated in the drawings the machine comprises an open metal frame including cornerv standards 1 preferably composed of angle iron, said standards supporting alower rectangular frame 2 and an upper frame. 3. Approximately centrally disposed and rising at the side of the frame areheavy stand- 'ards 4 constructedpreferably of I-beams.

The motor M' for operating the machine is mounted on a standard 5 extending transversely of the machine and carried. by the side members'of' the lowerframe 2.

I Extendingtransversely and lying within the frame is a cylinder 6 supported upon a shaft 7, the shaft 7 being journaled at each end in'movablefbearings 8 slidably mounted in openings 9 ,in the web of standards 4. The bearings .8 are raised and lowered by bearing adjusting mechanism of known construction which is operated the hand rod 10. The cylinder 6 constitutes theplaten upon which the work is fed to receive printing impressions from the printing roller.

As it is desirable to adapt the machine to receive, material of various thicknesses and to adjust the pressure of the work against the printing cylinder, the machine has been arranged so that by the operation of the hand rod 10 an extremely accurate adjustment of the shaft 7 may be effected.

The type cylinder 11 is carried on a shaft 12 which is journaled at each end in permanently adjusted bearings 13 mounted at thetopof the standards 4. The axis of the shaft 12 1s 1n parallel vertical alinement with the axis of the shaft 7 and since the shaft 7 1s adjustable vertically the space be tween the proximate peripheries of the cyllnders 6 and 11 may be varied as requiredv for receiving the work at the printing point of varying thickness, so that regardless of the thickness of the work a uniform pressure is exerted thereon toeffect the printing as it passes between said cylinders 6 and 11 at the printing point. The mechanism for rotating the cylinders 6-and11 in synchronism comprises a pinion 14 attached to the drive shaft 15of the motor which extends beyond the frame work at one side ofthe machine. The pinion 14 meshes with and drives a large gear wheel 16 which is fast on an extended end of the shaft 7 An intermediate pair of gears are arranged in a movable bearing 17, said mov-.

able bearing being supported at the junction of links 18 and 19, theouter ends of which are'respectiv-ely pivoted upon. shafts 7 and 12. The pair of intermediate gears are mounted upon a common shaft 20 which is revolubly mounted in the adjustable bearing 17. The pair of gears are in parallel vertical planes and the inner one 21 of said gears meshes with the large gear 16 and the outer one22 of said pair of gears meshes .with a gear 23 whichis mounted upon the link 19, the gear 23 in turn meshing with and driving a gear 24 secured to an extension of the shaft 12. The gear 24 has a releasable connectionv with the shaft 12 in the form of an adjustable cone clutch 25 of known construction. The gear 24 is ar-. ranged so that itv may be rotated in adjusting operations without rotating the shaft 12 and thereby the cylinder 11, so that after the adjustment is effected the-gear wheel may be locked to the shaft 12. I

It will be observed that the drive connection whereby the shaft 12 is driven permits the elevation of the axis of the shaft 7 to be changed without throwing out of mesh the driving connection between the two cylinders. Obviously, as the shaft 7 is lowered the axes of the pair of gears 21 and 22 is drawn inwardly, preserving the meshing engagement between the gear 21 and the gear 16, the normal adjustment of the axes of the gears 22 and 23 and between the axes of the gear 23 and 24. By this arrangement it will be seen that the two cylinders 6 and 11 may be driven in synchronismregardless of the adjustment of theshaft 7 upon which the cylinder 6 is supported.

The mechanism for feeding the work to the printing point between the cylinders comprises an endless belt or chain 26 which operates over alined sprockets 27 and 28, said sprockets being carried respectively by shafts 29 and 30 journaled in bearings 31 and 32 on the upper face of the frame 3. The shaft 29 is disposed near one end of the frame and the shaft 30 is arranged in parallel alinement therewith but near the printing cylinders. The sprockets 27 and .28 are arranged so that the endless belt or chain 26 extends longitudinally with the frame of the machine at a position intermediate of the width of the machine. At one side of the belt 26 is a series of permanently fixed revoluble rollers 33, said rollers being arranged in supports with the axes thereof parallel in ahorizontal plane and inclining forwardly toward the right hand side of the machine. At the right hand side of the belt 26 is a second series of rollers 34 which are in alaterally adjustable support comprising side members35 and end members 36,,the end members 36 being adjustably supported by cross bars 37 'carriedby the frame of the machine; Thus the entireframe in which the rollers 34 are supported may be moved toward and awayfromthe belt 26 so that the feeding mechanism is adapted to receive material ofdifferent widths. When the adjustment has been effected the support may be locked in position by set screws 38, which look the end members 36 of the roller supporting frame with the bars The rollers 34 are arranged in the same horizontal plane with the rollers 33 and have their axes inclined outwardly toward the right hand side of the machine at thesame angle of inclination as the axes ofthe rollers .33.

At the outer side of the movable frame,

.in which the rollers 34 are supported, is a vertically disposed guide strip 39 for guiding-the edge of the work as iii is fed by the feeding mechanism to the. printing rollers. The belt 26 carries a number of adjustable lugs 40 which contact with the forward end of the fiat sheetsof work when the same are placed uponthe. rollers 33 and 34,- and the lugs extend above the horizontal plane of the upper surface of the two sets of rollers.

As the work is moved forwardly by the inward movement of the belt, exerting pressure upon the front edge ofthe work through the lugs 40, the fiat sheets aremoved'to the right hand side of the machine against the inner face of the guide strip 39 and at the same time fed inwardly toward the printing point. The feeding mechanism thus automatically adjusts the position of the sheets clearly shown from which View it will be observed that a sheet S of the work, after it leaves the roller, is raised by thejguide strip 41 to a horizontal plane coincident with the space between the cylinders 6 and 11. The guide strip 41 has sufficient resilience so that when the cylinder 6 is lowered the forward end of the strip will be depressed sufficiently to maintain the adjustment between the periphery of the cylinder at the printing point and the inner edge of the guide strip so that regardless of the adjustment of the cylinder 6, the work will always be presented in the proper horizontal plane to be received between the cylinders 6 and 11 at the printing point, f

In the rear of the cylinders is a work discharging mechanism comprisinga number of longitudinally disposed and parallel alined belts 42 which operate over rollers 43 supported on shafts 44 journaled in brackets 45 mounted on the upper face of the frame of the machine. Both the belt 26 and the belts 42 are movedin the same direction, that is from the forward. end of the machine toward the rear thereof, by driving mechanism comprising a gear 46 which meshes with the large gear wheel 16, the gear 46 in turn meshing with and driving a pinion 47 fast onthe forward oneof the shafts 44, thereby rotating said shaft 44, The shaft'44' carries alsprocketwheel 48, and the inner'one of the shafts 30 carries a sprocket wheel 49. i A belt connection-50 operating over the sprockets 48 and 49 pro,-

myself therefore to the exact construction shown and described, but'what I claim and vdesire to secure by LettersPatent, is
