SHEET-FEEDING MECHANISM.

To all 'whomz't may concern.'

Be it known that we, JOHN STOGDELL STORES and JAMES D. REIFSNYDER, citizens of the United States, residing at Moorestown, county of Burlington, and State of New Jersey, and Philadelphia, inthe county of Philadelphia and State of Pennsylvania, respectively, have invented new and useful Improvements in Sheet-Feeding Mechanism, of which the following is a specification.

This invention relates to printing presses, and similar machines having means for automatically feeding sheets, blanks, or other articles, into the machine.

The invention is particularly applicable where the sheets or blanks are to be fed ordinarily without exercising great care asA to their' alinement, as they enter the machine, but which at times must be fed in a particular relation or alinement. For this reason the invention is particularly applicable to a printing press in which the sheets may be fed to be printed if desired without using great care, but which may at times be alined carefully so as to bring about accurate register, such register is desirable particularly where the sheets are printed on both sides, or where border lines vare used of different colors which will not present a good appearance if they are not properly alined.

A principal object of the invention is t0 provide an automatic feeding mechanism which may be used ordinarily to feed the sheets directly into the machine with which the feeding mechanism is employed, but having coperating with it a registering mech-H anism 'which may or may not be used as desired. When in use the registering mechanism operates to insure a proper allnement or register of the sheet as it goes into the machine. Y

A further object of the invention is to provide a construction for this purpose which is very simple and "readily operated so as to change the machine fromthe ordi-I nary feed to the register feed.

A further object of the invention is t0I arrange and construct the parts in such a.

way that it is unnecessary to make any changes in the connections to the feedingmechanism or the 'registering mechanism.

in shifting from the ordinary feed to the" registering feed.

'Further objects of the invention will appear more clearly hereinafter.

In the vdrawing which illustrates a preferred embodiment of our invention, Figure 1 is a side elevation, certain parts being broken away, showing a printing press to which our invention has been applied. This View illustrates the invention operating with the registering mechanism active or opera-tive. Fig. 2 is a longitudinal vertical section through the machine showing the parts in the same relation illustrated in Fig. 1. Fig. 3 is a longitudinal vertical section also broken away but illustrating the feeding mechanism operating to deliver the sheets directly to the machinethe registering mechanism belng held in an inoperative or inactive relation. Fig. 4 1s a conventional plan of the machine, showing the frames which carry the feeding mechanism and the registering mechanism as though they were disposed in a horizontal position.

Referring morel particularly to the parts, 10 represents the main frame of the machine which may be a printing press, such as illustrated, comprising a form cylinder 11, an impression cylinder 12, and a take-ofi' frame or cylinder 13. The'form cylinder may be driven by means of a gear wheel 130, which may mesh with a driving gear not illustrated.

I n applying our invention to such a press we prefer to arrange the feeding mechanism and registering mechanism so that the feeding mechanism when operating in the'ordinary manner is disposed adjacent to the impression cylinder to which it delivers the sheets directly to be printed, and we prefer to arrange the registering mechanism in such a way thatat this time it may be held in an inoperative relation, but when desired instead f having the sheet pass by a direct path from the feeding mechanism to the machine, we may interposethe registering mechanism in its path, so as to give a proper control 0f the sheet to insure proper register as it passes into the machine.

The feeding mechanism is preferably mounted on a movable feed frame 15, which is prgferably supported at its inner end on a pair of links 16, pivotally attached at 17 to the sides of the main frame. The feed frame is preferably provided at its outer end with short legs 18, which coperate with means lon the 'main frame in such a way that the table or feed frame 15 can be in a In order to'holelthefeedframe most conveniently in these two positions, we prefer to provide the end of the main frame 10 with sockets 19- and 20, which receive large pins 21 formed at the lower ends of the legs 18. The frame 10 preferably presents an inclined face 22 between these sockets, so that the feed frame can be pushed upwardlyfrom the position in which it is indicated in Fig. 1. ,The studs or pins 21 drop into the sockets 19.

On the feed frame 15 we refer to provide feeding mechanismi23, and) provide an arrangement enabling this mechanism to be driven from a 'moving part on the main frame Ain both of the positions of the feed frame. This construction issuch that the driving connection is maintained in `throwing the feed frame from one position to the other without necessitating t e removal or reassembly of any parts'. For this purpose we prefer to employ the feeding mechanism ofthe type illustrated, comprising a reciprocating part preferably in the form of a plate 24, which is arranged to reciprocate longitudinally between side guides 25. This feed plate is preferably reciprocated by a link 25 attached to its under side and connected to the upper end of a rocker or'rocking lever 26 supported on one of the legs 18, and having its lower arm connected with a vlink 27. This link is preferably extensible, so as to adapt it to rock the lever 26 in either position of the feed frame. For this reasonthis link is preferably formed o'f two ` sections 27 and 27", one of which is of tubular form and receives the other section which may be rigidly secured to it by any means such as the set screws 28. The lmoving part to which the extensible link 27 attaches, is preferably a disk 29, which may be co-axial with the form cylinder 11, and in order to provide for adjusting the position of the feed plate, we prefer to 'connect tl1e` disk or wheel 29 adjustably to the cylinder."

' For this purpose we prefer to provide the cylinder with circumferential slots 30, in which clamping'bolts 81 are received, the said bolts being'v carried by the said disk,

small worm 32 mounted on the disk and meshing with the teeth of a worm wheel 33 rigid with the cylinder.

Evidently by rotating the thumb head 34 on the worm the disk 29`can be nicely adjusted.y The extensible rod 27 performs the function of a pitman or connectin rod, its end being connected to a crank pin 35 on the disk. It is evident that when the cylinder rotates the disk 29 moves with it'and the motion will be imparted through the rocker 26 to the reciprocating plate. For the purpose of holding a pile or supply 36 of sheets or blanks on the feed plate We prefer to pro vide alining plates 37 Ywhich engage the side edges of the pile, and these alining plates4 are adjustable inwardly in suitable brackets 38 which may be secured in different positions on the feed plate. For this purpose the brackets are preferably provided with dowel pins 39 which may be received in any one'of a plurality of sockets 40. Similar sockets 41 are provided in a row opposite the sockets 40, and coperatin with a movable locking pin 42 which may ie pivotally supported at 43 and pressed by a springL 44, and an adjusting screw 45 is provided which may swing the pin laterally after it is in its socket as .indicated in Fig. 3, so as to lock the bracket in position. Each alining plate or gage 37 is provided with a clamping screw 46 mounted in the bracket for holdin it in position. The outer edge 47 of the p1leof sheets is alined by means of an alinmg plate 48, which may br adjusted longitudinall of the feed plate through the medium o a slot 49 inthe feed plate, and a clamp 50 carried on plate 48.

When thefeed plate 24 slides away from the cylinder 11, the forward edge of the pile of sheets 36 overhangs the forwardedge of the plate, but the sheets are all vsupported by means of flat straps or bands 51 of stout tape or similar material, one end of these tapes. being vattached at 52 .to the forward edge of the feed plate so that the tapes form loops passing around a horizontal feed roller 53 mounted in the feed frame. The outer portions of these tapes pass around guide rollers 54 and their ends are connected to springs 55 on the under side of the feed plate. These springs maintain tension 1n the tapes so as to resist the welght of the sheets. The roller 53 is preferably rotated at each reciprocatioiof the feedplate by means of a rack 56 which meshes with a pinion 57 on the roller, and the roller is of tubular form and provided with a perforation 58 so that when connectedlwith a vacuum device a partial vacuum in the roller operates through the perforation 58 to at-l tract the lowermost sheet of the p ile and carry it partly around the roller lwhen the feed plate moves forwardly. In this way the sheet which is being fed is made to pass under the inclined lower` face 59 of a finger 60 which projects toward the feed table. The sheet then passes downwardly under Ia presser roller 61 onto the impression cyl-Y inder 12, where itis engaged by grippers not illustrated. l

The presser roller 61 coperates with a roller 62, which roller 62 is continuously rotated by a mechanism which will now be described. This mechanism preferably comprises bevel gears 63, 64, carried vco-axially on the axes of the pivot pins at the ends of the links 16, the motion being` imparted from the bevel gear 64 to the bevel' gear 63 through a shaft 65 extending radially from the point 17. This shaft is suitably mounted on brackets. In order to retain the pile of sheets 36 in position we prefer to provide a keeper device 66 preferably in the form of hooked arms mounted on a rod 67, said arms being pulled over toward the pile of sheets by an adjustably attached spring 68. The

Vinner end of the table or feed frame 15 preferably projects beyond the axis of the gear 63, that is beyond the axis of the upper pivotal connection of the links 16, and this overhanging portion is preferably provided with a cross head 69.l This cross head may' l present means for holding the finger 60',

accomplish this we prefer to provide regis- 4 tering mechanism 72 on a movable register frame 73. This frame is preferably supported 'pivotally at 74 on the overhanging lend of the feed frame. The outer portion of the register frame may be provided with set screws 75 which may rest on the upper face ofthe main frame 10.50 as to support the registering mechanism in its operative position, as indicated in Fig. 1.

The registering frame preferably includes a rigid feed plate 76, the upper end of which lies near the point of tangency between the rollers 61 and 62, and this feed plate may be provided with feed belts 77, arranged to be driven at a high speed, and guided overrollers 78 so that the upper run of the belt moves rearwardly on the upper face of the feed plate 7 6. The rollers 78 are carried on a shaft 79 which may be driven through ter frame.

an idle gear 80 meshing' with ay gear 81, which is rigid with the bevel gear wheel 63, said idle gear 8O meshing with the gear wheel 82 rigid with theshaft 79. These belts 77 may be tightened by means of belt tighteners 83. As the sheet comes from the rollers 61 and 62 it passes down the feed plate 76 .and passes under presser rollers 84 which run upon the. upper faces of the belts 77, said rollers being mounted on arms which are adjustable on a bracket 85, which may be secured at any point desired in a slotted bzlir 86 extending longitudinally of the feed p ate.

.We provide means for arresting the advance of the sheet being fed on the registering mechanism, and then we aline, and release the sheet at a predetermined time which will insure that the sheet will have the proper register or alinement with relation to the printing matter 87 on the form cylinder. For this purpose we' prefer to provide the lower end of the feed plate 76 with projecting fingers 88, and near the ends of these fingers stops 89 are provided, the ends of which project into the path of the sheet and engage its forward edge as it advances. These stops 89 are preferably providedrwith spring fingers 90, which may be adjusted by small screws 91 so as to adjust them toward or away from the coperating fingers 88. These stops 89 are preferably mounted so as to be adjusted toward or away from the feed plate 76. This may be accomplished by means of an adjusting nut 92 mounted on an adjusting screw 93 coperating with a check nut 94. In addition to this a dowel pin 95 may be provided for guiding the stop 89 as it is adjusted in or out. These adjusting screws 98 are mounted in rocker arms 96 which support the stops 89, said rocker arms being adjustably secured on a. transverse rockshaft 97 which extends across theregis- Arrangements have been made for rocking this rock shaft 97 at a predetermined moment so as to swing it rearwardly and upwardly and release the sheet. This mechanism will be described hereinafter.

Beforethe sheet comes against the stops 89 its motion is partially arrested by 1li-ears of a brake device 98, the lower end of which retains a ball 99 resting on the feed plate 76. As the sheet passesunder this ball 99 it `has -to raise it off the table, and this acts as a brake tending to stop the sheet. After the sheet comes against the stops 89 it is shoved over against an alining gage or bar 99 at one side of the feed plate, see Fig. 4. In order to shove the sheet over against the gage 99 we prefer to provide a cross bar 10() on which is mounted a pusher 101 which is adapted to overhang the edges of a sheet. and which presents a shoulder 102 adapted to engage the edge of the sheet. This pusher 101- also comprises a sleeve 103 whichv may be attached at any desired point on the rod or bar 100 by reason of a row of perforations or sockets 104 in the upper side or bar with which coperates a'removable pin 105 carried by the pusher.

The pusheris shoved over at a predetermined time by means of a cam 106, see Fig. 1, the edge of said cam operating to raise a lever 107 through the4 medium of the roller 108, said lever having a link 109 connecting the same through a'rock shaft 110 with an arm 111,'said arm being connected by a short link 112 with the bar 100. A spring 113 attached to the bar tends to push it against the sheetwhenever the cam 106 will permit.

In order to effect' the releaseI of the sheet at any predetermined time we provide the cam 114 which is mounted on the same axis with thecam l106, and this cam rocks an arm 115 fulcrumed at 116 and carrying a roller 117 which rolls on the cam. The outer `end of the arm 115 connects by a link 1.18 and arm 119 withthe aforesaid rock shaft 97. A helical spring 120 is provided around the rock shaft which tends to hold the roller 117 firmly against the cam 114. One end of this sprin may-be provided with a rigidly secured co lar 121 having a' socket 122 which may engage a pin on the `rpck shaft in different. positions so as to regulate the force of the spring, the other end of the spring being secured at 123 to the side of the register frame.

In order to enable the cams to be adjusted so as to regulate the time at which the sheet is releasedthe cams are provided with circumferential slots 124 through which clamping bolts 125 pass, attaching the cams to a vgear wheel 126, said gear wheel being rotatably mounted on a stud 127 on the main frame, and driven by a gear wheel 128 on the shaft of the take-off cylinder 13. The takeoff cylinder is driven from a gear wheel 129 meshing with the gear wheel 130 rigid with the slide 14. The take-off cylinder may be provided with a gear wheel 131 meshing with the hgear wheel 129. In order to drive the shaft 65 to drive the; j f,eed belts of the registering mechamsm wep'refer to provide a pinion 132 which mesheswith the gear wheel 131, and which is rigid with a gear wheel 133, meshing with a gear wheel 134, rigid with the bevel gear 64. In order to guide the sheet in passing onto the impression cylinder 12, we prefer to provide curved guide shoes 135 which may be arranged as indicated in Fig. 2, and secured to a cross'- bar 136 carried by the register frame.

The general mode of operation of the machine will now be described. When theordinary feed is in use the feed frame 15 has the position shown in Fig. 3, and the sheet is held in an uppermost position, such as y that indicated in Fig. 3, supported on a cross heador cross bar 69. In order to shift to the other position or relation with the re 'stering mechanism in operation, it is o y necessary to raise the outer end of the feed frame 15 to disengage it from the socket 19 and then drop it down until it is supported in the socket 20. At the same time the register frame may be swung forwardly so as to come down to thel position in which it is shown in Fig. 1.4 Before moving the feed frame 15 to this osition the set screws 28 should be loosened) -so as to permit the extension of the extensible rod 27. When the register frame swings down into the operative position of the registering mechanism the rollers 108 and 117 rest on their corresponding cams so that connection is made in this way to drive the registering mechanism. Evidently by swinging the register frame upwardly the connection from the register frame is disconnected.

It is understood that the -embodiment of the invention described above is only one of the many embodiments or forms of the l invention, and We do not wish to be limited inthe practice of the invention, nor in vthe claims, to the embodiments set forth.

The use of the pneumatic hose 53a enables connection to be maintained to the pneumatic feed roller in any position of the feed frame, so that a pneumatic feed is particularly advantageous when used in the invention set forth.
