The present invention relates to new and useful improvements in printing presses and has for its primary object to provide, in a manner as hereinafter set forth, a printingpress em- .5bodyinga novel construction, combination and arrangement of parts through the medium of which either sheets or a web may be fed to said press.

Other objects of the invention are to provide a press of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in operation, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of thefollowing specificaticn, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:--

Referring now tothe drawings in detail, it will 0 be seen that the embodiment of theinvention which has been illustrated comprises a supporting structure or frame which is designated gen;- erally by the reference numeral 1 and in which the cylinder 2 is operatively mounted in the usual 55 manner. The supporting structure or frame 1 taken substantially on in section through the FIE of the press includes uprights 3 having mounted on their inner sides pairs of spaced, vertical strips 4 defining channels 5.

The strips 4 thus constitute guides for the vertically adjustable rack bars 6 which are fixed on the ends of upper and

lower rods

7 and 8, respectively, said rack bars 6 having tongues 9 in the form of strips thereon which are engaged in the/channels Extending transversely between the uprights 3 is ashaft'lo having gears 11 fixed thereon which are engaged with the rack bars 6. Hand wheels 12 are fixed on the ends of the shaft 10. Mounted for swinging movement upper rod 7 are arms 13 between which theimpressionroller 14 is journaled- The'reference numeral 15 designates an elevating rod for. the impression roller 14 which is adjustablyand detachably connected to one of the arms 13, as at 16. The lower end of the elevating or lifting rod 15 is connected to a bracket 17 by a 23.5,

toggle 18. The reference numeral 19 designates a foot plate on the supporting structure 1 of the press from which a hanger 20 depends. Mounted for rocking movement on the hanger 20 is a spider 21 which is operatively connected to the toggle 18 by a link 22. Pivotally cc. mounted on the free end portions of oppositely extending legs of the spider 21 are foot pedals 23 which are operable in openings 24 provided therefor in the plate 19. The

shanks of the pedals 23 are notched, as at 25, for s5,

engagement with the plate 19 for releasably looking said pedals in depressed position. 1 It will'thus be seen that the impression roller 1% may be conveniently swung upwardly away from the cylinder 2 when desired by simply rocking the spider 21in a direction to elevate the rod 15 through the toggle 18. It will further be seen that the supporting means for the impression roller 14 may be conveniently adjusted various sizes of cylinders by rotating the shaft 10.

vertically as desired for If desirable or necessa-ry, any suitable means may be provided for-retaining the rack bars 6 in vertically adjusted position The reference numeral 26 designates an inclined, vertically adjustable feed board having a guide 2'7 thereon. Extending transversely across thelower portion of the feed board 26 is a series of openings 28, the purp ently. set forth. I The fe ose of which will be presed board 26, is adjustably supported by pairs oflinks 29 which are pivotally connected to nuts 30 which are mounted on the oppositely threaded end portions of screw shafts 31 which are coupled to in unison by a chain an each other for operation d sprocket connection 32.

A hand wheel 33 is provided for raising or lowering the feed board 26.

Journaled in the free end portions of the arms 13 are brackets 34 (see Figure 5) in which a feeder frame 35 is secured by set screws 36. It will thus be seen that the feeder frame 35 is mounted for swinging movement in a vertical plane on the arms 13. Stop lugs 37 which project from the arms 13 limit the downward swinging movement of the frame 35.

Fixed on the free end of the frame 35 are

hearing blocks

33 and 39 in which a shaft 40 is journaled, said shaft 40 projecting laterally beyond the block 38 and having fixed on its projecting end portion a pulley 41. Fixed at spaced points on the shaft 40 are feeding disks or wheels 42.

The bearing block 38 has slidably mounted thereon an elongated housing 43 having longitudinal slots 44 therein which accommodate the shaft 40. Journaled longitudinally in the housing 43 is an adjusting screw 45 which is threaded through the bearing block 38 and which has fixed on one end a hand wheel 46. Journaled transversely on the lower end portion of the housing 43 is a shaft 47 having

pulleys

43 and 49 fixed on its end portions. pulley as and around a pulley 51 on the upper portion of the housing 43, the flights of said belt being engaged with diametrically opposite sides of the pulley 41 for actuating the shaft 40. The pulley 48 rides on a cam 52 which is fixed on the cylinder shaft 53, said cam 52 constituting means for driving the feeder and for periodically raising and lowering the same.

Extending between the

bearing blocks

38 and 39 is a bar 54 having mounted thereon a plurality of stops 55 which are operable in the openings 28 in the feed board 26. The construction of the feeder is such that when. the disks or wheels 42 are raised to inoperative position by the cam 52 the stops 55 are projected above the upper surface of the feed board 26 for engagement by the next sheet that is to go into the press. Of course, when the feed disks or wheels 42 are lowered into engagement with the'sheet the stops 55 are retracted or lowered to permit the passage of said sheet. This is illustrated to advantage in Figure 7 of the drawmgs.

When the low portion of the cam 52 reaches the pulley 48 the feeding mechanism swings downwardly by gravity for engaging the disks or wheels 42 with the sheet, as will be apparent, and when said low portion of the cam passes the pulley 48 the feeding mechanism is raised to inoperative position. However, it will be noted that the feeder disks or wheels 42 are in constant operation. When the impression roller 14 is swung upwardly or raised the lugs 37 support and raise the feeding mechanism. When a web or roll, instead of sheets, is to be fed into the press, the feeding mechanism is simply swung upwardly and forwardly to an out of the way position on the An endless belt 50 is trained around the i 2.
