Serial No. 587,015.

This invention relates to feed and control means for power operated printing presses, such for instance as check printing machines.

An object of the invention is to provide means for releasing the printing drive means as the check or other form is brought to printing position.

Another object of the invention is to provide means for automatically securing the check in printing position.

The invention consists in the novel construction and combination of parts, as set forth in the appended claim.

In the accompanying drawings:

Fig. 11 is a detail of the drive clutch releasing means.

Fig. 12 is a left-hand side elevation of the printing drive clutch member.

Fig. 13 is a detail side elevation.

In the accompanying drawings the invention is shown, for convenience, as used in a check printing machine.

In the contemplated mode of operation a check 1 (Fig. 1) is placed upon rearwardly extending fingers 2 and 3 with the left hand edge against the inner surface of a guide member 4 and its forward edge against the projections 5 of a guide plate 6. The guide member 4 extends rearwardly and forms part of a reciprocating frame 7. The guide plate 6 is adjustably mounted upon the forward end of the reciprocating frame by means of the thumb screws 8. The fingers 2 and 3 are stationary parts and adjustablv secured to the top cover plate 9 of the machine by bolt and slot connections 10 and 11 (Figs. 3 and 4). The reciprocating frame 7 is slidably secured to the cover plate 9 by means of guide rails 12 and 13.

When a form is placed in contact with the frame, as previously described, the operator, grasping the raised forward edge 14 of frame 7, slides said frame rearwardly whereupon the projections 5 will push the check rearwardly beyond the support fingers 2 and 3 to printing position.

As the check is brought to the printin line 84 its rear edge will be positioned overlying the forwardly extending fingers 15, 16 and 17 and beneath projections 27 and 28 as shown in Fig. 3, for the purpose hereinafter described.

The frame 7 is provided with suitable cam edges 83 and will slide beneath the finger 16.

The following means are provided to simultaneously stop the rearward movement of frame 7 and secure the check in position for a printing operation.

Securely fast to the right-hand forward end of. the frame 7 is a bracket or plate 18 provided with a shoulder 19 and a rearwardly extending arm 20, the end of which is bent upwardly to form a cam surface 21 (Fig. 10).

Mounted upon the framing of the machine by pin and slot engagement is a slide member 22, normally in forward position, and provided with a recess 23 as shown in Figs. 1, 3 and 8.

A rock arm 24, pivotally mounted in suitable slot openings of a bracket 25, fast to the framing'of the machine, has loosely mounted upon its free end a two armed lever 26 provided with downwardly projecting ends 27 and 28. The lever 26 is loosely secured to the rock arm 24 by rivets 29 in such manner as to be held rigid horizontally but flexible vertically.

'18 will contact the forward edge of the slide 22 and move said slide rearwardly to bring the cam edge 31 thereof into active relation with a corresponding cam surface 32 of the block 30 (Fig. 8). At this instant the cam face 21 of the projection 20 of bracket 18 contacts a corresponding cam surface 33 of the rock arm 24. Rearward pressure offrame"? now causes the cam surface21 acting on surface 33 to force the rock arm downwardly until the projections 27 and 28 contact the surface of the check, which is thus forced against the lingers 16 & 17 and thereby held securely.

As arm 24 is rocked downwardly the block 30 is forced'down into the recess 23 of slide 22, as shown in Fig. 9, thesurface 32 of block 30 merely forcing the slide 22 rearwardly as the block seats in the recess 23. 30

Thus the above-described co-ordination of the rock arm 24 with the frame member 7 makes it possible to stop the'positioning movement of the check simultaneously 'with the operation of the securing means and elimi nates the possibility of throwing the check out of positionin rapid operation as well as'the danger of printing out of position or crumpling of the check which might occur in slow operation. p v

The following means are provided to release the power operated printing means:

As bracket 18 is carried 'rearwardly by the frame 7 an ad'ustable set screw 34 mounted upon said bracket will contact the free end.

35 of a bell crank lever 36 (Fig. 10) pivotally mounted at 37 upon the framing of the ma chine, and rock said lever in a clockwise direction. During this movement shoulder 38 of said bell crank lever contacts a projection 39 of lever 40, 'pivotally mounted at 41 upon the'framing of the machine, and rocks said lever counter-clockwise to free its end 42 from beneath a stud 43 fast to the printing head 44. Clockwise movement of bell crank lever 36 will also impart downwardmovementto' a comiecting link 45, having its upper end pivotally connectedto hell crank 36 and its lower end pivotally connected to the free end of a rock lever 46, fulcrumedat 47 upon the framing of the machine.

Fulcrumed at 48 upon the framing, as shown in Fig. 11, is a bell crank lever 49. Pivot'ally mounted at 67 upon one arm of said bell crank lever is a spring tensioned latch meinber 50, provided with a tooth 51 normally frame of the machine.

The arm 55 of bell crank lever 49 extends beneath a projection 56 (Fig. 10) of rock lever 46, and as said lever is rocked downwardly about point 47 by connecting link 45, the projection 56 will contact the arm 55 of hell crank lever 49 and cause said bell crank lever to be rocked in a clockwise direction as viewed in Fig. 11. v

The clockwise movement of hell crank lever 49 will cause the tooth 51 of latch 50, contacting stud 52, to rock the latch member 531 in'a clockwise direction about point 54.

A shoulder 57 of latch 53 normallyoverlies ,a projection 58 of a pawl 59 pivotally mounted at 60 upon a plate 61, fast to shaft As latch 53 is rocked, the shoulder 57. will release pawl 69 and said pawl,"under infiuence of spring 62 will be rocked to bring surface 63 into engagement with the teeth of a ratchet 64, loosely mounted upon shaft and forming a part of the drive means'f The engagement of pawl 59 with ratchet 64 will cause. the disc 61 torotate shaft 85 clockwise, as viewed in Fig. 12, to operate the 87 of an m ;-p a11 mounted at 89 upon the framing. 1 1

- Uponrotationof shaft 85 (counter-clock,-

wise as viewed in Fig. 10) the cam. 86 will free projection 87 and arm 88 will be rocked downwardly, about point 89, under influence of a spring 90. Y

Pivotally mounted at 91 upon the arm 88-is a connect-ingrod 92 having its upper end pivotally secured to the printing head 44; The printing head 44 extends transversely of the machine and is suitably supported at its ends uponthe shaft 93, as shown in Figs. 2 and 10. 'As arm 88 is pulled downwardly by spring connecting'rod 92 will rock the printing:

head 44 downwardly to cause platens 94, suitably supported by said printing head, to press the check or other form, against type drums (not shown) mounted within the body of the machine. v

As shaft 85 continues to rotate, the surface 95 of cam 86 contacts the lower'surface of projection 87 and rocks arm 88 upwardly and connec ing rod 92 will lift the printing head 44 to normal position.

During the rotation of the disc .61 a pin65, fast to said disc, will contact a projection 66 of latch 50 and raise said latch about point 67 to disengage the shoulder 51 of said latch from the stud 52 of latch 53, whereupon latch 53, under influence of spring68, will be re turned to normal position, in the path of movement of the projection 58 of pawl 59.

At the end of a revolution the projection 58 of pawl 59 strikes the shoulder 57 of latch 53 and rocks said pawl out of engagement with the ratchet 64.

Suitable locating means are also provided, comprising a spring tensioned arm 69, adapted to enter the notched opening 7 0 cut in the periphery of disc 61.

Upon completion of a printing operation, the frame 7 is drawn forwardly by the operator, whereupon the bracket or plate 18 will release the arm 24, a light spring 71 serving, however, to keep a slight pressure of projections 27 and 28 upon the check.

Securely mounted upon the frame 7 are inclined fingers 72 and 73 (Figs. 1, 3 and 13) so arranged that as frame 7 is drawn forwardly they will pass beneath and to a position just forward of the check, the slight pressure of projections 27 and 28 holding the check in position as fingers 72 and 7 3 pass beneath.

During the last portion of the return move ment of frame 7 a stud 80, mounted upon said frame, contacts a projection 81 of the slide 22 and moves said slide forwardly.

The forward movement of slide 22 will cause the cam surface 31 of said slide, acting on surface 32 of block 30, to raise the arm 24 and release the check.

Forward movement of frame 7 is limited by means of the bracket 18, contacting a stop stud 82, secured to the framing of the machine.

A new check is now inserted and the frame 7 operated in the manner previously de scribed, whereupon the raised rearward sur face of the fingers 72 and 7 3 will contact the forward edge of the printed check and push the same rearwardly beyond the fingers 15, 16 and 17, to the position shown in Fig. 2.

As frame 7 is again brought forward, preparatory to receiving another check form, check 1 will contact the surfaces 74% of fingers 15, 16 and 17, which will hold said check as frame 7 is drawn from beneath it.

Check 1 now drops into a suitable hopper 75, but in so doing the right hand edge of said check will contact the surface 76 of plate 9 thus allowing the left hand edge of the check to fall first, which is a Well known means of loose leaf stacking and needs no further explanation.

To adjust the machine for checks of different width, loosen the thumb screws 8 holding plate 6 and set the check with the printing line opposite the arrow and adjust plate 6 to bring its projections 5 against the forward edge of the check. Slide the frame 7 forwardly and adjust the fingers 2 and 3, by means of slot and bolt connections 10 and 11, to a position slightly forward of the advanced projections 5 of plate 6.
