The present invention relates to sheet feedingapparatus and particularly to that type in which a feed table is associated with a supply table, and mechanism is provided for de i vering the paper from the supply table to the feed table, and from the feed table to the instrumentalities that operate on the individual sheets, as for example, a ruling ma.- chine, printing press, folding machine or the like.

One of the objects of the invention is to provide feeding mechanism that will successfully operate on any size of sheet within the maximum capacity of the apparatus.

K further and important object is to provde nevel means for transferr1ng the sheets from the supply table to the feed table, and forcontrolling the transfer and feeding operations at the delivery end of the feedng table 'by mechanism that is dependent on the amount of materie] or number of sheets at sad delvery end of the feed table.

Figure 12 is a perspective view of a portion of the belt showing the adjustable side walls of the supply table.

Figure 13 is a similar view of the feed table.

In the embodiment disclosed, a feed table 10 is employed, supported on suitable standards 11, and in turn supporting thereabove a supply .table 12. The supply table 12 is inclined reversely to the feed table 10, and has its lower end mounted in suitable frame brackets 13. Its upper end is carried by supportin g rods 14 suitably based on fraine brackets 15 at the lower or delivery end of the feed table 10.

The upper or supply table 12 is provided with upstanding side walls 16-16, and an endless belt of a width substantially equal to the maximum distance between said side walls, has an upper stretch 17 operating over the table between said side walls. This belt passes around adirecting roller 18 interposed between the lower end of the supply table 12 and the upper end of the feed table 10. Its rear end asses around a guide roller 19 10- cated at t. e upperend of the supply table 12. The guide roller 19, as shown more particularly in Figure 11, is journaled in brackets 20 slidably mounted in boxes 21, and having slots 22, through which holding bolts 23 pass. Adjusting screws 24, threaded thiough the rear ends of the boxes 21, bear against the rear ends of the brackets 20. The side wall 16 is adjustable across the adjacent margin of the belt 17, its upper end bein supported by a hanger 16 slidably mounte on a cross rod 16 that extends over the table and the belt. The cross rod is supported in brackets 16 mounted on the table on opposite sides of the belt. The lower end of the side wall 16 has an outstanding slotted arm 16, through which is passed a set screw 16. The centra]. portion of the side wall has an.outstanding stem 16 slidably mounted in a collar at 16 that is fixed to the table. A set screw 16 serves to hold the stem against movement in the collar. This wall constitutes an abutment wall. against which the pile of paper is placed. The opposite or rear side wall 16 has its upper end carried by a hanger 16 that is slidably mounted on the cross rod 16. Its lower end is slidably mounted on a cross rod 16 fixedto the lower end of the side wal] 16.

A roller 16", ournaled on the central porton of the side wall 16*, is adapted to ride upon the belt and thus prevent frictional contact between the side Wall and the belt When the side wall is adjusted, as indicated in dotted lines in F igure 12. With this arrangement, it Will be evident that the active width of the tablemay be varied to suit any Width of paper from a very small size to the maximum that can be placed on the belt.

The lower or feed table 10 has side walls 25 and 25, and over said table operates the upper stretch of an endless belt 26, having a width substantially equal to the maximum space betvveen said side walls 25. The belt 26 at the upper end of the table 10 passes around a guide roller 27, and at the lower or delivery end of said table passes around a roller 28. A tension roller 29 rests upon the lower Stretch of the belt and is journaled in swinging arms 30 pivoted, as shown at 31, to the frame brackets 15.

The side wall 25 has a limited adjustment over the belt 26 similarto the side Wall 16, except that as said side wall 25 does not constitute an abutment against which a pile of paper is placed, the intermediate support is eliminated. In like manner the sidewall 25 is adjustable toward and from the side wall 25, corresponding to the adjustment of the side wall 16. The roller, in this instai1ce, is preferably, though not necessarily, located at the upper end of the side Wall25, as shown at 25".

A driving shaft in the form of a roller 32 is journaled in the frame brackets 13 and is eared, as shown at 33, to the roller 27.

.earing. 34 also transmits motion from the roller or drive shaft 32, to the drum 18. This driving shaft or roller 32 projeets from one side of the frame and has fixed thereto, a ratchet wheel 35. A bell crank 36 is journaled on the projecting portion of the shaft 32, and as shown in detail in F igure 5, one arm of the bell crankhas pivoted thereon a pawl37 that Operates on the teeth of the ratchet Wheel 35. The pawl is spring-pressed, as shown at 38, so as to maintain its engagement with the teeth. The other arm of the bell crank 36 has pivoted thereto a link 39 extending longituclinally of the feed table 10 to the delivel(iy endof the same. Saidend of the link is a justably and pivotally connected to the depending arm 40 of a bell crank pivoted, as shown at 41, on the frame bracket 15. The other arm 42 of the bell crank is pivotally engaged with a stud 43, carried by a collar 44 ad ustably mounted On a reciprocatory actuating plunger 45. The plunger 45 is vertically disposed, its lower end sliding in 2.

guide 46, its upper end being slotted, as shown at 47, and sliding on a transverse shaft 48 extending across the delivery end of the machine. A spring 49, operating on the lower end of the plunger rod 45, serves to normally move it downwardly. The upper end of said plunger rod carries a roller 50 operating on a cam 51 carried by the shaft 48.

It Will thus be evident that When the shaft 48 and cam 51 are rotated, the plunger 45 will be reciprocated, thereby swinging the bell crank 40-42, causing the longtudinal reciprocation of the link 39 and the back and forth movement of the pawl carrier bell crank 36. This Will obviously cause the stepby-step rotation of the roller shaft 32 and theconsequent movement of the belts 17 and 26 and the transfer roller 18. By shifting the pivotal mounting of the link in the depending arm 40 of the bell crank, the efiective throw of the link and therefore of the pawl can be varied in order that the feed will be changed to the length of the sheets passing through the apparatus.

The operation of these parts is controlled by the thickness or number of sheets at the delivery end of the feed table 10. The plunger 45 is provided with a laterally ex tendrig lug 52, and a swinging latch 53 ivoted to the frame bracket 15, is adapte to IIIOVG to and from a position beneath and in the path of the lug 52. Swinging move ment of this latch is limited by oppositely arranged adjustable stops 54. A rock shaft 55, journaled in the said frame bracket 15,

is provided with a depending arm 56, in the lower end of which is slidably engaged a link member 57, and said link member has a slot 58 in which is engaged a pin 59 carried by the latch 53. A spring 60 on the link member 57 serves to normally secure its movement with the arm 56, and an adjusting nut 61, threaded on the outer end of the link member. The shaft 48, which carries the plunger actuating cam 51, also carries a cam 62, and operating on said cam, is a roller 63 journaled on the free end of an arm 64 that is carried by the rock shaft 55. The cams 51 and 62 are so related that nor mally the latch 53 Will be withdrawn from beneath the lug 52 When the actuating plunger 45 is permitted to drop by the cam 51, and said latch is alternately moved into and out of the path of said lug on each reciprocation of the actuatin plunger 45. Secured to the inner end of t e rock shaft 55 is another crank arm 65, having at its free end a ball or head 66 which is adapted to rest upon the sheets moved to the delivery end of the table. This crank arm 65 is mounted on the rock shaft 55 and is capable of adjustment longitudinally along the same. body ofshets is at 01' below a predetermined thickness, the arm 65 and head 66 Will be allowed to swing downwardly, thereby per When the mittng the outwardmovement of the latch 53 from beneath the holding lug 52, but if the thickness o the sheets increases, said arm and hemd act as a detector, and will prevent the full rocking movement of the shaft 55, thereby preventing the outward movement of the latch 53 to its inactive position. As a consequence the In 52 will rest upon the latch and the actuat1on of the eeding means will be stopped. As soon, however, as the thiokness of the pile decreases snfiioientlythe arm will again be permitted to drop, the latch will resume its normal swinging movements to an inoperative position and the operation will again begin. By adjusting the nut 61 threaded on the link member 57, the osition of the arm 56 will be varied, there y raising or lowering the detector hall so that the amount of paper that is permitted t0 corne Operation on by the suction roller can be Ahy suitable mechanism may be employed forfeeding the sheets from the delivery end of the apparatus, such as combing or delivering rollers, rubber push fingers, or suction devices, well known to those skilled in this art. In the present embodiment there is disclosed a suction roller 68 carried by the shaft 48. This roller may be of the type disclosed in Patent No. 1,494303, dated May 13, 1924.

In order toinsure the proper passage of the paper from the upper belt 17 to the lower belt 26 and around the transfer roller18, the following mechanism is preferably employed. An upper guide roller 69 is looated above the transfer roller 18 and a lower guide roller 70 is located below said transfer roller and adjacent to the roller 27. Around these rollers pass sets of endless tapes 71 that operate against the portion of the upper belt 17 g:ssing around the roller 18. These tapes are ven by gearing 72, extending from the gear of the roller" 18 to the upper guide roller G9. Extending alongside the roller 18 is a supporting rod 7 3, on which are journaled a pluraity of oarrying arms 74. Each of these arms has journaled on the opposite sides of its free end tension rollers 75 around which a set of tapes 71 pass. The arms 74 are adjustable along the supporting rods73 and en be held at any desired position by collars 76 seoured by set screws 7 7, the eollars beng located in bifurcations in the pivoted ends of the arms 74. Guide pulleys 78 are prefmtbly mounted on intermediate portions of the a.rms .74 and around them the said tapes pass. S ecured to the supporting rods 73 are ether arms 79 connected by a rod 80, on which aan: slidahly mounted collars 81. Connecting these collars with the carrier arm 74 are spaings 82. The structure is such that the springs 82serve to hold the tapes 71 taut. It

will be evident however, thatas the sheets pass aarsr beneath it for around the transfer roller 18, the portions of the tapes coacting therewith will be separated from the roller, and this separation is permitted by the swinging of the arms 74 against the tension of gers 83 are pivotally mounted, .as shown at 84, on a cross rod 85 at the delivery end of: the upper table 12, and have th eir free ouds extending over the transfer roller 18 and to pointsadjacent to the tapes 71. ()ther directing fingers in the form of curved springs 86 have hookedends 87 embracing the supporting rod 73, and have their lower ends resting on the guid e roller 70, these fingers extending betweenthe tapes 71.

With this construetion,it will be evident that a pile of sheets placed upon the upper stretch of the belt 17 on the supply table 12, will be carried downwardly, and. passed around the transfer roller 18 on to the belt of 1 the feeding table 26, the transfer mechanism insuring the proper frictional 01 carrying engagement with the belt around the roller 18. The sheets in turn will be carrie d longitudinally along the feed table 10 on the belt 26 and the sheets will be suocessively delivcrcd rom the machine by the suction roller 68.

During the reciproeation of the actuating plunger the cam 62 is causing the swinging of the arm 64, thereby alternatly raising and lowering the ar1n 65,- having the hall or head 66 thereon, so that the paper sheets can pass thereunder. As long as the sheets at the delivery end do not exceed a predetermincd number, the ball will drop suffieiently to permit the shaft to turn and withdraw the lateh 53 from beneath the lug 52, but whenever the supply exceeds that desired, this detector will not be ermitted to drop because of the paper beneat it and consequently the latch cannot swing outwardly, but will maintain it-s position beneath the lug and hold the actuating plunger against operation. The use of belts on the table has been found peculiarly advantageous in that sheets of any width less than the distance between theside walls mag, be fed without diiliculty and the only adjustment that may be necessary is of the side walls and transfer tapes7 1. These being located in sets, said sets can be relatively adj usted and will cooperate with the transfer roller and the directing fingers to insure the proper delivery of the sheets from the upper to the lower table.

1 From the oregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without fur ther description, and it will be understood that various changes in the size, shape, proportion and minor details of construct-ion may be resorted to without departing from the. spirit or sacrificing any of the advantags of the invention.
