Application filed July. 5,

State of Illinois, have invented certain new and useful Improvements in Printing.

Presses and like Machines, of which the following is a. specification. N

This invention relates to improvements in printing presses and like machines and has for its object to provide means whereby sheets of paper or like material in advancing to, the printing-rolls are accurately positioned with relation thereto and in advancing-past a selected point are subjected to guiding mechanism that will automatically act in case of imperfections in the margin of the sheets or when thesheet of paper or like material is feeding into the machine in imperfect alignment either by reason of the sheet being placed before or beyond the side guiding mechanism whereby the stopping action of the. machine is actuated.

In the drawings:

Fig. 1 is a fragmentary side elevation of part of a printing press and automatic feed ing mechanism showing the improved device applied thereto. 7 1

Fig. 2 is a plan view 'of part of the mechanism shown in Fig. '1, parts being omitted and other parts broken away for clearness of illustration.

Fig. 3 is an enlarged side elevation of the side'guiding mechanism with the improvements applied thereto. I

Fig. 4 is a detail view of the mechanism embodying my invention.-

Fig. ,5 "s a sectional view taken on lines 55 of Fig. 4 and looking in the direction of the arrows. v f

Fig. 6 is a view similar to Fig. 4 but in different relative position of the several parts.

Fig. 7 is a detail ofthe detector witha sheet improperly fed entirely under the con-' tacting arm.

. Referring particularly to Figs. 1 '2 and: 8 of the drawings, the frame 1 has mounted thereon an automatic paper feeder 2 which is of the type used with a flat bed two revolution cylinder press and to. which .the de-' vice embodying the invention isa plied. 3 indicates one of the printing cylin ers. The sheets of paper 4 are advancedsuccessively.

' over. the sticks 5 and are subjected to the ac- 1919. Serial No. 30 ,843.

side guide is of awell known type and comprises gripping shoes 7 pivotally mounted on an angle bar 8 which bar is pivoted at 9 to bracketarm 10 and has means for causing the shoes to engage the paper and adjust PATENT- OFFICE,

tion of theside guide mechanism 6. This the paper sidewise of the machine, The bar I is provided with spring 11 having one end fixed at 12- to thehub 13 of the angle bar, 1 and has its other end secured to a nut '14 having threaded engagement with the pivotj pin 15. The action of spring 11 isto rockthe angle bar on its pivot and cause the shoes to engage the margin of the paper sheet and hold it between the shoes and base. plate 16 of the bracket 10.

The bracket 10 is adjustably secured at 17 to a clamp 18 mounted on the side guide ops crating shaft 19. The shaft 19 terminates.

in a rack extension 20 slidable in the bearing 21 in the standard 22: Theside guide oper-' ating shaft is reciprocated by reason of the actuating of a segmental gear 23 on stub shaft2 l engaging the rack 20. This action is produced by the pull rod 25 secured to the.

cross head 26 on the outerend'of the stub shaft 24. I The upper' angle arm 8 of the:

angle bar 8 is provided with a seat ,8 toreceive roller 27 on the arm28 of a bell crank 29 pivoted at, 30 to the bracket 10.. A depending arm 31 of the bell crank 29 .is caused v to engage a lug 32 on'the'inward movement of the shaft 19 transverselyof. the travelof the paper sheet and thereby trip the'angle bar and through the action of. thejspring 11 rock the angle'bar downward bringing the shoes in contact with the margin of the paper and securely holdingthe paper between the' shoes 'Tand the base plate 16 of'brack'et 10. The spring 11 has just enough tension, when regulated, for heavy or light paper stock, so that the grippers merely shift the paper against the side lugs and then'slip off}, a If tension is too great, the paper will cramp and the stock be mutilated. The sheet of paper will be carried transversely of its travel when shaft. 19 moves outwardly by the mechanisms just described until the arm 31- of the bell crankengages the lug 33 which lug and also the lug 32 are secured to a bed plate 34 adjustably mounted on a bar 35 secured to the table 2 of the automatic feed mechanism. At the point of contact ofthe bell crank arm 31 with the lug 33. (shown in Fig. 3),v the paper will have moved to a point where the margin thereof will be therefrom and the sheet of paper will be advanced through the printing press in the usual and well known manner. The grippers remain in a closed position with the sheet firmly grasped until the latter edge of the sheet contacts the guide stops 36, as shown in Fig. 2, at which time the jaws are opened and the paper isr'eleased'.

Referring tothe bed plate 34 it will be noticed that the inner end orthat next to the edge of the papersheet projects beneath the "path of travel of the incoming sheets oi paper and is provided with an extended member 37. Upon the base member 37 are posts 38 and -39: A'bar, 40 is-pivotally mounted'at 41 to post 38 and projects toward the incoming sheet's oif'paper and has adepend ing finger 42 which finger is above and slightly one side of themargin of the paper when the paper is properly placed with relationto the side g-uidestops 36. The forward end" or bar 40 passes through a slot 43 in the post 39 and is normally held upward by a lever 44 pivoted at 45 to a post 46,611 the base 37, said l'e-ver havinga spring 47 secured thereto a'iid the spring having i'ts other end secured at 48' to post 46 thereby causing an upward pull'cn the lever- 44 and through contact of' the-lever 44 and bar 40 the latter is held upand in contact with a pin 49 secured to a locl 'ri n-glatchi member 50 pivoted at- 51 to bar '40 the other end of which latch member is caused co-engage the stop bar 52 secured "to 'post 49 As shown in Figure 4, the latch lever 50 in its-downwardmovemen-t will centact'the pin 50 in serted in the post-39 and having an end projecting into the space The position-of the pin 50 is predetermined in orderthat it will not contact the latch 'member 50 during normal operation. lVhen-the finger 42 afall's intov the slot 61, the latch member" 50 will contactth'e pin-50 and: will beftripp'ed up- Ward on: its pivot 51, so that the latch "mem ber' 50: will not intercept the 'hook portion- 62' of lever 53.

A latch member 53'i'spiv-otal 'ly secured at 54tothe post 46 and has 'a cam ii'ace pro jection 55 thereon adapted to cont'act'the end 516 of le'ver- '44. As show'n in Fig. 1,the link 57'is secured at 5 8't0 the latch and has-its other end pi-votally secured to an arm 58 which arm is fixed to a shaft-59 known as the kick-off shaft. The shaft 59 is rocked through the actuation of the pull rod 60 and its associated parts which are of a well known structure and form no part of this invention. "In preventing the reciprocation of the'pull rod 60, the detecting device functions the'starting (and stopping mechanism of the pri'ning'press' to which it is attached not-shown in the drawings, nor explaihed in tion, to each other the specification. This starting and stopping mechanism of an ordinary printing press is not apart of the present invention and its only importance is that it is functioned by the operation of they detecting device when it fails to contact with the edge of the paper sheet. All of the aforesaid mechanisms are assembled and are operated in timed rela- It will be understood that as the shaft 59 is rocked the latch member'53 through its connections therewith will be rocked onits pivot and caused to travel forwardand back carrying the cam faced projection thereof beneath the end of the lever 44 thereby rockingthe lever on its pivot andreleasi'ng the other end of the lever from contactwith the bar 40 thereby allowing the bar 40 by gravity to descend and in sodoing bring the finger 42 of the bar 40 into contact with the margin of the paper which contact with the incoming paper or like material will cause the'b'ar 40 to come to rest, and be returned to its former position When'the shai't 59 causes a return movement of the bar to its former position. While the shaft 59 is causing through-the aforesaid connections therewith a vibratory action of the bar 40, the side guides are performing their functions whereby the sheets of paper or like material are brought to proper position against the stops 36. As the paper passes beneath the finger 42 of the bar 40, should a sheet through improper'alignment from any cause or through i'ai l'u re of the side guides to perform their function not come within the vertical plane of action of the bar and finger or should the margin of material be mutilated the finger wi l l fai1to be stoppedand will drop into the aperture 6 1 and infidoing so'will causethe bar 40 to fa-ll'bel'ow a point which willall'ow the re turn of the latch member 53 by reason of the; tooth 62011. latch 53' engaging the bar 40, preventing oscillating motion thereby arresting the rocking of shaft 59 and inso doingcausing through the usual means not shown a stoppage ot the entire press mechanism. It will-bereadil'y'uinderstood'that an overfeeding of the paper will produce a like result by reason of the projection-"63 ot the finger 42 contacting-the paper and holding the oscillating arm '40 -in a position where the pivotal latch 50 is engaged by the hook portion 6-2 of the swin-ginglatch member 53, as shown in'Eig. 7. Tlratipart of the l'atch member, which is engaged by this hook por tion, is a notched projection on its lower edge which moves down'into positionby r0- tation or the latc-hupon its. pivot 51. The actuation of the latch member being stopped in this manner has alike e-ifect to the previous mode of stopping a machine, as explained where the'paper is not contacted by the arm 40, *as shown in Fig. 6.

It is believedthat an'understanding of the operation of the improvements embodying the invention will be had without further detailed description.

This invention is notlimited to the details of construction.

I claim as my invention:

1. In a printing press having an automatic stopping device, the combination with a means for feeding the paper sheet to the press, of a pivoted vibrating element having contacting relation with the lateral edge of the paper sheet as it is fed to the press, operative connections between the pivoted vvibrating element and the stoppingdevice whereby the press is automatically stopped when the lateral edge of the paper is out of position.

2. In a printing press having automatic stopping mechanism, guide paper shifting mechanism, the combination with a vibrating element intermittently contacting a lateral edge of the sheet fed to the press, of operative connections between the contacting element and the stopping mechanism whereby the interruption of the actuation of the vibratory element will act to cause a stopping of the press when the material is improperly positioned.

8. In a sheet detector for printing presses, having automatic stopping and feeding mechanism, the combination of a detector device comprising a vibrating pivoted lever adapted to contact the paper sheet on one of its lateral edges, of a spring actuated pivoted lever adapted to lift the contact lever and having an actuating cam acting on the lifting lever, operable connections between the detector device and the stopping mechanism whereby the press is stopped when the sheets are improperly aligned.

4;. In a sheet detector for printing presses, having automatic stopping and feeding mechanism, the combination of a detector device comprising a vibratory pivoted lever adapted to contactthe lateral edge of the sheet during travel of the sheet, a cam actuated lever operating against spring tension and functioning the vibratory lever, operating connections with the automatic stop whereby failure of contact of the vibratory lever with the sheet will cause stopping of the press.

5. In a sheet detector for printing presses, having automatic stopping and feeding mechanism, the combination of a detector device comprising a vibratory pivoted lever adapted to contact the lateral edge of the sheet, a suspended cam latch and a pivoted lever actuated thereby and functioning the vibratory lever, operating connections between the suspended cam latch and stopping mechanism whereby the failure of'the vibratory lever to contact the sheet will produce a stopping of the machine.
