act description, reference being had to the.

accompanying drawings, which form a part of my specification.

My invention relates to the feeding mech anism for presses and other machines wherein the paper to be operated on must be automatically fed forward to the desired point, and is more especially adapted for use in connection with machines for folding and wrapping newspapers and periodicals, the mechanism being operated by the power used for drivin the balance of the press or machine to w 'ch my improved feedin mechanism is attached, it bein understood that the mechanism is propery geared to the balance of,the machine in such a manner as to have the papers fed forward at predetermined intervals, as will more fully hereinafter appear.

In the drawings, Figure 1 is a top plan view of my improved. feeding mechanism as applied to a machine for folding and wrapping newspapers and periodicals, only a portion of the machine being illustrated. Fig. 2 is a side elevation thereof, while Fig. 3 1s a longitudinalsectional view of the same.

Like letters of reference indicate identical parts the various figures.

A is a part of a fol ing-machine on which is mounted the feed-box B, provided with a series of rollers 11 in its bottom, of which there may be any suitable number, the rollers exten'ding, preferably, entirely across the bottom of the feed-box and having suitable hearings in the side walls of the box. Mounted in yokes or hangers b, which are adjustably secured to the rear walls of the feedbox, are rollers (1'. Endless tapes or bands 0 take about the rollers and are given movement thereby. The roller a in the forwardend of the feed-box B extends through one of the side walls of the box and is provided with pinion F, as shown in Fig. 1, which meshes with caring receiving power from the driving-s aft of the machine. This roller 0/ being revolved compels the endless belts 'or tapes 0 to travel in a similar direc-' able plate g,

tion. In order that the belts or tapes may operate, it of course is necessary to keep them taut, and for that reason the yokes b are made adjustable. Any slack that may occur in the endless belts or ta es can be taken up by turning the thum -screws d, which. take over the screwethreaded shank of the yokes, the shank ofthe yokes 6, passing throughthe rear wall of the feed box, being held in place by the thumb-screws d. I prefer to construct the yokes or hangers in.

this manner, as I believe it to bethe most convenient way in which to accomplish the result desired. l

, With the construction as shown in. the drawings and just described in order to keep the yokes b from turning the screwthreaded shanks are formed with a flat uper surface, as is usual in cases of this sort, and the thumb-screw e, (see Fig. 3,) which has its seat in the rear wall of the box B,

takes onto the fiat surface of the shanks when screw 6 is screwed down into place, and thus prevents theyoke b from turning. Of course it is understood that a similar thumb-screw c is provided for each yoke or hanger b. The box is provided with cut-out portions in its rear wall to permit of the screws 6 and access. thereto.

Thelower ortion of the front wall of the feed-box B is eft open, 'as-atf. (See Fig. 3.) The front wall of the feed-box is an ad ustwhose lower end is bent forward at an angle andextends in the direction in which the papers are fed.- This plate g is adjustably secured to the front side of the box, so that the opening between the bottom of the plate 9 and the endless belts or tapes beneath it may be varied according to the thickness of the papers or periodicals to be fed from the box. This plate 9 is provided with slots through which bolts it take, where- I by it is secured to the box B.

Taking through extensions *5 to are set-screws j, he d down in place and prevented from be ng shifted or jarred upward, enlarging the opening beneath and t we ermitting more than one paper to be passe throu h. Of course on the boxthe set-screws 1' might have their seat through 1 05 whereby the plate 9 is 1oo so that no adjustable plate 9,

when bolts k are loosened by turning the setout of the feed-box. Just forward of the box ,7 B is a shaft Zr, (see Fig. 3,) loosely mounted in the frame of the machine and provided with any suitable number of dogs 1, which are adapted to extend up above the to of the machine slightly and into the path oi the papersy, soi as to retard their, forward movement caused by belt m, mounted on rollers n and n, which are geared to the driving-shaft, andthus the papers are lined up," as it were, and the papers held until the dogs I are dropped out of their path.. The shaft "7r, on which the do s l are mounted, is operated by the bell-cran lever 0, secured at its end, which latter is secured to the shaft p. The bell-crank lever 0 is provided with a dependent arm g, which is adapted to ride on the cam'r, (see Fig. 2,) secured to the end of a shaft 8. This shaft s has also mounted, on it the bevel-gear s, which meshes with the bevel-gear t, mounted on shaft 13, which latter is shown broken away, as it is geared at its opposite end to the driving-shaft of the machine to which the feeding mechanism is attached.

It is apparent that the shaft 1c and the dogs Z mounted thereon are made to oscillate by reason of the bell-crank lever being operated by the arm g riding on the cam r, the dogs 1 dropping down by their own weight after the dependent arm gilhas passed over the cam r.

Mounted on' s areprovided with rollers v '0, which" are adapted to ride on the belts or tapes m. There may be as many of these bearing-roll- The pur ose of these belt and insure its being fe forward. The

arms a are securely fastened to shaft p so out of the box B and lined that when shaft is rocked by the bell-crank lever 0 they will be similarly rocked. It will be seen that the bearing-arms u and their rollers Q) will be brought or rocked down onto the paper on the belts m, while the dogs Z are tipped or rocked downward and out of the path of the paper which has already been fed up by the dogs 1, thus bearin the paper down on the belts m and compel g it to move forward with the belts m to the point where it is to be acted upon by the remainder of the machine or press.

I The bearing-arms u and; their rollers v are loosely mounted on the shaft 10 and are merely intended to hold the paper weight on the belt or tape m.

l pfefer to have mounted in front of the feedox B some flat spring guiding-blades aft p are arms a u, whichdown by their w, which guide the paper in a horizontal plane as it is being fed out of the box B.

These blades are simply flat pieces of steel or other metal, preferably bent, as illustrated, and are mounted on a cross-piece w, which is slightly above the path of the paper.

In order'to keep the papers to the front end of the machine, with the lower ones slightly in advance of the upper, I provide the retainer or supportin arm 0, which is-secured to thecross-piece which may be adjustably secured on top of the feed-box, so as to accommodate papers of different sizes.

In practice the papers to be fed are stacked and arranged so that each paper will lie in the same direction, and the retainer or supporting arm C is arranged a distance away from ,the forward end of the receptacle substantially corresponding at its top with the width of the papers to be fed, thus bringing the lower free end of the retaineror supporting arm C a distance away from the forward end of the receptacle slightly short of the size or width of the papers. It will be seen that this retainer or supporting arm by reason of its forward curvature will not permit the papers to lie fiat in the bottom of the rece tacle, but will hold them up at therear en on an incline, thus forcing the forward end of the papers against the front of the receptacle at a point sl ghtly below the rear ends, permitting the undermost paper, of course, to

come into contact with the belts or tapes 0. This arrangement prevents any crowding of the papers at the forward end of the receptacle.

I also find that it. is preferable Where the papers to be fed are not of the full width of the feed-box I and in order to'have them feed from the feed-box at the same point to have a gage-in the feed-box against which the ends of the papers be laced, thus insuring all of the papers being ed out evenly and so as to be in a position for the bearing-rollers to' grasp them alike. 'This-ga' e, E may be of any desirable form, preferab y as illustrated,

.witha vertical and horizontal arm, the horizontal portion or arm being provided with a slot, as shown inFig. 1; through which a bolt takes, whereby it is secured to the feed-box top. The slot permits the gage to be adjusted or set fordifferent-sized I apers.

The roller n, about which be t m takes, is provided with a pinion G, (see Fig. 1,) which is driven by the remainder of the machine.

As will be seen, the bottom paper is fed out of the box, and this is made possible by providing the forwardly-sloping plate g, thus permitting the papers to be placed in the opper or feed-box B with the lower papers sli htly forward of the upper. he hopper or feed-box is pivotally mouirti at its rear-end, as at ed on the machine the front simply'being supported on the machine 1n any suitable manner, thus permitany occasion that may arise.

I have thus described what proved feeding mechanism; but it will be readily understood that slight modifications may be made without departing from the spirit of my invention.

Having thus described my invention, what 7 I claim, and desire to secure by Letters Patent, is

1. The feeding mechanism for presses and the like, comprising a receptacle with an opening in its forward lower end, said forward end being adjustable and inclined at its bottom, means for securing it in its adjusted position, rollers arran ed in the. plane of the receptacle-bottom, belts or tapes adapted to take about said rollers and pass along the bottom of said receptacle, and mechanism whereby the tension of said belts or tapes is regulated, in combination with mechanism normally held in the path of the paper fed from thereceptacle and in advance thereof, and means for holding the paper in its horizontal path, substantially as shown and for the purpose described.

2. The feeding mechanism for presses and the like, comprising a receptacle with an ope in its forward lower end, said forward end being adjustable and inclining outward at its lower end, means for securing it in its adjusted position, rollers arranged in the bottom of said receptacle, belts or tapes adapted to take about saidrollers, one of said rollers being adjustable, whereby the belts or tapes are kept under proper.tension, mechanism against-which the rear ends of the papers to be fed rest and whereby they are forced forward against the inclined lower part of said forward end, means normally eld in the path of the papers fed, whereby they are alined, and mechanism for retainl believeis the v simplest and best construction of my iming the papers in their proper path, substantially as shown and described.

3. Feeding mechanism for presses and the like, comprising a receptacle with an opening in its forward lower end, said forward end being adjustable, means for securing it in its adjusted position, rollers arranged along the bottom of the receptacle, one of said rollers being adjustably mounted, belts or tapes taking about said rollers, gages 'slidably mounted on the receptacle whereby the papers are held in the desired path and against the forward end of the receptacle, mechanism normally held in the path of the papers fed from the receptacle whereby they are alined, and means for. holding the papers down to their proper horizontal path, substantially as shown and described.
