adjustably secured thereto at their ends the brackets 15. Rotatably mounted in one of the brackets 15 is a friction roller 16 which is normally out of contact with the impression-cylinder 11 but is designed to engage the cylinder when a sheet of paper is inaccurately placed or fed to the machine and is to be ejected, as will be fully described. The roller 16, when operated, drives a sprocketwheel 17 over which passes a chain 18 to a second sprocket-wheel 19 that is secured to a stub-shaft 20 which is mounted for rotation in the bracket 15. Secured to the shaft 20 is a gear 22 which meshes with the gear 23 on the shaft Qtthat carries the rubber-faced sheebejecting wheels 25. These wheels, by reason of the connection just described, will rotate in a direction opposite to the direction of rotation of the press impression-cylinder 11, as will be clear from the use of the gears 22 and Q3,the direction of rotation of the impression-cylinder being indicated by the arrow 26, and the direction of rotation of the sheet-ejector wheels being indicated by. the arrows 27.

It was stated above that the wheel 16 is normally out of engagement with the impression-cylinder 11, and it should be stated that the ejector wheels 25 are also normally out of contact with the press feedboard 10, as

shown in Fig. 1 by the space 28. The structure which sustains the roller 16 and the r0llers 25 in an inoperative position, is the liftrod 29 that is attached at its lower end to a cam-operatedlever 30 that is pivotallysecured to a casing or bracket-member 31 which is secured to one of the uprights 12 by means of the foot-piece 32. The upper end of the liftrod 29 is vprovided with an angular-shaped arm 33, the upper surface of which engages a bent arm 31S (see Fig. 2) that is attached to an elbow-shaped member which is secured tothe rod the arms of the elbow-shaped member are indicated at 36 and 37 The arm 36 is pivotally connected to a link 38 which, inturn is pivotally connected to a slidable rod 39 at the point 40. The rod 39 moves in a bracket 41 that is part of the bracket 15 and engages the feed-board to elevate the ejector wheels 25 out of contact with the sheet of paper when the same is accurately positioned. The arm 37 engages a setscrew 42 by means of which the pressure of the roller 16 on the impression-cylinder 11 may be varied to cause it to rotate. The sheet-ejector wheels 25 are independently adjusted by means of the mechanism shown in Figs.12 and 13, in which shaft 24 that carries the wheels 25 is mounted for adjust ment on the bracket 15 by means of the setscrew 25 that passes through the slot 25 in the plate 25 This plate turns ori pivots.

about the shaft 20, and bymeans of the set screw 25 the pressure of the sheet-ejecton indicate wheels 25 may be varied orthe feedboard 10.

clamped, by means of the screws 43, in

In the normal operation of the machine, the frame'brackets 15 which turn on the rod 13 at 13, are'raised and lowered by means of the cam-operated lever 30 which is attached to the lift-rod 29' at 46 and is pivoted to the'casing 31 at 47. "The cam=operated lever 30 is formed with a shoulder 48that engages the slidable stop 451 on the downaward movement of th'erod 29. When the shoulder 48 engages the stop 49, which is normally projected into the. path of this shoulder, as shown in Fig. 7, the downward movement of the sheet-ejecting wheels 25 and the rollerQlG is" prevented Should this slidable stop 49ihowever; wheii'a sheet is inaccurately rfilace'd; be withdrawmas will beexplained, e wheels 16 and25 will be opera ated from the press cylinder 11 and thes ejected or evented from entering thepress. The camever 30 is operated by means of a roller 50'whichen agesfithe ca'm5l" -that is securedto the shai I leaves the.

If the stop 49 is retracted by means of i the compressionspring 5/; when released by the electrofmagnets 55', should a sheet be inaccurately placed on the feed-board, leaving any one of the sheet-engaging contacts closed, permitting'the electro-magnet '55 to operate, the lift-rod passes by the stop 49 and the sheet-ejecting wheels '25 are operated as described. When thej'roller 50 rengages the concentrid surface '53, the lift-rod is pushed upward and the arms 14 elevated as described to permit the placing of a sheet on the feed-board 10 beneath the sheet-ejecting.

\vheels25 and against the press-guides.

Coming now to the description of the mechanism by means of which'the rod 49' is released and then reset in the position shown in Fig. 6 and the means by which the same is retracted when a sheet is inaccurately fed and the sheet-ejecting mechanism operated. f

56 designates a main gear'or operating member which is driven from the pinion 57 which, in turn, is driven from the gear 58 that is operated by the gear 12 motive pover being transmitted thereto by an suitable means. The gear 58 is mounted for adjustmnt" in the arms 59 which are pivotally supported on the main shaft 52. One of the arms is rovided with an adjusting device d at (30 which is merely a slot and screw construction.

The g r 56 is' formed with a groove 61 v V Referring to Fig. 10, GT designat'esa bearelectromechanical and inthis groove is secured a curvedshaped ca1n62 and a second cam 63 of less length than the cam 62. but terminating in -.the same plane as the cam G2, as indicated stilt. (see Fi 10). The thickness of the cam 63 is greater than the cam (32. The purpose of the earns 62 111x163 is to set the latch in locking position, which consists of an electro-magnet havling-the latch 65 which normally retains the stop 49 projected shown in Fig. 7. This latch is provided with a roller 66 which is normally retained elevated by a suitable spring (not shown). The latcli,ho\\'ever; is of common construction.

g in which is mounted a rod (38. Attached to one end of this rod is a crank-arm (39- or finger which lies back of the lever .70 (sec Figs..8 and 10'). The other end 68 is connected by means of a pin-and-sl0t ,connectjon 71 and 72- with amember 73 which is formed wlth an arm 7 a and a roller V 1 75 pivoted thereon. as shhwn in these figures. l

Secured to the side of the main gear-wheel 56' another cam construction 82, shown in Side elevation in Fig. 10. This cam is formed wit-ha cut-out portion 83 and an in r-lined surface 84: with which a roller 85 on the lever engages. formed with a. second cut-away portion 86 having a beveled surface 87. When tho roller 85 engages the inclined surface 84:, the leverTO, which is pivoted at the point 88 is moved transverse to the face of the wheel 56 against the tension of the spring 89. The pin 88 is connected to the arms 9" Of the lever 91. which latter pivotis pivoted to the sides 9:? and 93 of the frame at 9i. The lever 91 extends forwardas shown in Fig. '5 and to the outer end is attached the link 95 that is connected to the usual device, which operate the press cylinder trip so that the type will not engage the same when there is no sheet on the press cylinder. The arm G9,.when rocked by the roller in setting the latch and locking the stop rod d9, simultaneously operates the lever 'ZO to hold it out of operative position with the cam 82.

The cut-out portion 86 of the cam 82 with its inclined surface 87 -is for the purpose of permittingthe roller to drop into portion 86 without a jar to the ciit-a'way the mechanism. The purpose of the inclined surface Set is to force the lever 70 outward away from the operative edge of the cam 82 to render the link 'lfhe next step in the operation of the mechanism is to follow up the movement of the lever 70 by means of the finger 69 which will force (by an additional distance outward away from the iace of-the cam 82, and prevent the roller from engaging the operative, edge .of the cam When the electromechanical lock holds the stop 49 extended, as shown in F ig. 7 the roller 7 5 is away from the bottom of the groove Gland during the normal operation of the wheel 56 the roller 75 passes idly over the upper surface of the lower cam 62, but when the latch is tripped or withdrawn by the circuit being' closed the roller engages the bottom of the groove 61 and is then forced inwfnd by means ofithe cam 62 and brought into engagement with the cam surface 63, the outer face of which higher than the outer surface of the cam 62, to reset the latch and stop 49. The electro-mechanical latch is secured to' the frame by means of "the hracket-arm :96 by means of. the" screws '97. I A

"The cam51' which causes the lift-rod 29 to operate is provided. with an adjustable contact device 98 secured in place by means of theslot-bolt connection 99. This contact evice engages inoperative.

means of the roller 75). this lever This cam is also a fixed contact device IOO-to closed and the same energized, which will nets 55 which extends to the sheet-contact the contacts at 111" are opened, there will be which the wires 101 and 102 are attached, wire 102 being connected to one terminal of the electro-mag'nets 55, a wire 103 being connected to the other terminal of the magdevices 104, 105 and 106 which are connected in parallel with the wires 101 and 103. A detail view of the sheet-engaging contact is shown in Fig. 3, wherein the contact-carr'yin plate is shown at 107, a blocl: of insulation at 108, to which is secured a contact wire 109, a pivoted fin er 110 which engages the wire 109 at 111. K spring 112 WhlCh is attached to the finger 110 normally closes the contact 111. The source of electrical energy is supposed to be connected at the point 118. The finger 110 is located in a slot or opening 110 in the plate that is secured to the press-feed table and, as shown, extends down below the surface of the table to prevent the paper gaining access below the finger when the sheet is placed on the table 10. The operation of the sheet-engagingmechanism shown in Fig. 31 is as follows: When a sheet of paper is placed on the press table 10 with two of its 'ed es engaging each of the pivoted contact gers 110 and plates 107 each finger is moved on its pivot against the tension of the spring 112 to open the circuit to the magnet 55 at the contact point 111 (see Fig. 3). If the sheet is accurately positioned for printing on thepress-hoard 10 it is drawn into the press by means of the usual paper gripping fingers (not shown). Simultaneously with the op eration of the gripping fingers to draw the sheet into the press the rod 13'is rocked by the usual prcss mechanism to elevate the contact plates 10? to allow the sheet thereunder by the contact supportin arms which are secured to the rocking shat t 13.

The 0 eration of the mechanism is as follows: W en a sheet to be printed is placed on the press feed board 10 against the contact fin ers110 of the contact devices 104, 105, an 5106 and the stop-plate 107, if the sheet isaccuretely positioned so that all of no current through the magnet 55. Should, however, one of the contacts at 111 be left closed, the circuit to the magnet 55 will be cause the armature 55' of the latch to be attracted, with the result that the stop 49 will be withdrawn, permitting the lift-rod 29 to pass by the stop 49 and allowing the roller 16 to engage the press cylinder 11 and the sheet-ejecting wheels to engage the in accurately fed sheet of paper and eject the same. \Vhen this operation takes place, the

This] face 62 ofthe cam 62 and pushesthe arm 81, back into the lockedposition shown in Fig. 7. At the same time the stop 49 is projected outward and the finger 09 follows up the movement of the lever on its pivot 88 to move the roller '85 out of the path of the cam 82. When the machine tripped to eject a sheet, the roller 85 engages the cam 82 to operate the levers 70 and link 95 to automatically throw the press cylinder away from the type-form to prevent its receiving an impression thereon in the usual mannerl" If the sheet is accurately fedto present invention.

From the description it will be seen that I have produced an inaccurately-ted sheetdetecting device that can, by reason of its compact structure of lever mechanism, be placed or attached to machines now in use, which have the uprights 12 and gear 12 The term type has reference to a print ing form that is either fiat or circular in form.

The feed-board at its forward edge is sup plied with a flexible or elastic t ngue 110 shown in Figs. 1 and 3. The opening 110 in the flexible tongue receives the contact fin er 110, as shown in these figures.

t should be stated that the guide contact devices and 106 against which ihc'shcct of paper is placed to accurately position the same are secured to, and form a par-t ot the usual printing press construction. "lhcse contact devices are automatically raised and lowered by the press mechanism at the proper time to allow the sheet of paper to be ted to the press cylinder after it is accurately positioned. in practice 3 the contact guides 105 and 106 are mounted on arms that rod which is parallel with the rod 13, and, as stated these guides are raised and lowered by the usual press mechanism. i
