cutting mechanism, or other device Where itf is desired to have individual sheets fed successively.

In my mechanism I employ means friotionally engaging the paper and shoving Vforward one or more sheets thereof, and an overhanging shield adapted to engage such v fed sheets and retard all. of them but one,

allowing its movement to continue. The invention covers such mechanism broadly.

The invention is hereinafter more fully described and its essential characteristics are summarized in the claims.

In the drawings, Figure l is a front elevation of my feeding mechanism adapted to carry a number of sheets standing vertically on edge and successively feeding the innermost sheet; F ig. 2 is a side elevation of such mechanism; Fig. 3 is an enlarged vertical cross 'section through the shield and mainl feeding roller. Fig. 4 is a perspective view of the shield.

Referring to the parts shown .in the draw ings by reference characters, A represents any suitable frame; which carries the paper support, the advancing mechanism and my retarding shield. The paper support as shown comprises the vertical plate B, adjustable side guides B', and the adjustable bottom support B2. The guides are held on the plate by set's'crevvs C passing through slots b in the back plate,- whereby these guides may be adjusted in and out and clamped in place. A bottom support B2 is similarly clamped in place, adjustable by reason of the verticalI slot b. It 1s provided with .an upwardly extending tongue b2 which is adapted to bear on the front side (if a pile of papers placed vertically on the support.

Above the paper support and placed substantially tangentially with the outer snrface of the plate B is the main feed roller D. Thisroller preferably has an elastic periphery, provided by sleeves d on a core, and is rotated in any convenient manner as indicated by the gear D'. In front of this roller D is a roller E which also preferably has an elastic periphery and is spring-pressed toward the roller D. Theblock of paper (indicated by X in Fig. 3) stands vertically with its upper portion between these two rollers.

The spring-pressing of the roller vE may be accomplished in anysuitable manner. As shown in the drawing. it is provided by extending the shaft E of the roller E and mounting its end on a. pair of arms F which are pivoted at a stationary point. as, for example, on ears b3 turned forward from the back plate B, suitable springs being provided t-o act on the arms F. These springs are shown at G. They surround. the pin H on which the arm F is pnnnalcd and are secured at one end to a stationary pin J pro jecting from the ear b3 and at the other end to a disk K surrounding the stud ll and ad-v justably clamped to arm F by the screw le acting through a slot in the disk. By this means the force of the spring on the arm F may be nicely adjusted to cause the roller E not. only to bear with the desired pressure on the paper but to have the t\vo ends bear equally. The pin J by passing through a slot. in the lower end of the arm F also forms a stop limiting the movement of the arm and prevent-ing straining ofthe spring.

Snitably supported above the parts described is my shield X. which consists of a trough-like member extending horizontally in such position that the sheet of paper nearest the roller D may be f"ed into it. As shown, this shield has a vt ical portion n, the rear face of which is a iery slight distance in front of the front face of the plate B. From this vertical portion the shield curves rearwardly for approximately a semi- -circle, as shown at n From the lower end opposes snllicient resistance to the advancingr y the retarding force on an)v of the subsequent of the vertical portion extends a horizontal flange ne adapted to lie 'over the most of the block of paper. This tlange 1F may be turned downward at its end as at gli". and then turned laterally to provide ears n* by which the shield may be secured to the fraaie A by screws l).

Q represents a plate or table at the rear of the roller D and tangent with its upper surface; v

t and R2 designate a pair of rollers which are intended as an illustration of any suitable mechanism to which the paper is to be f ed.

ln the mechanism described, the paper is placed on the .support b r the Aoperator swinging oatwardlythe roller li and dropping the paper into place on the bottom piece b2 and between the `guide strips li'. 'l`he roller E then being released holds the block 0f paper against the front side of the roller D as shown in Fig. 3. A\'ow when this roller D is rotated in the right hand direction, as indicated by the arrow in Fig. 3, the rear sheet of paper and several of the adjacent sheets are fed upwardly along the rear face of the vertical pta-tien n of the shield into this shield. The upper edges of these fed sheets abut against the curved portion of the shield. as indicated at .r in Fig. 3. This paper that there is less friction between the rear sheet' and the next adjacent sheet than sheets, and accordinglr the rear sheet slips on the next to the rear sheet and its upper edge buclrles'in the trough until the free edge curves under the extreme edge of the shield N. whereupon this sheet passes ont from the shield and rearwardly above the table Q, as shown at a" in Fig. 3. The continued rotation of the roller D shores thisreleased sheet rearward until it passes to the mechanism indicated by the rellers R and R2: then. as the bottom edge of the sheet clears the roller D, this roller acts on the next sheet. which is correspondingi)v advanced, and 'so on. The roller E acts ordinarily as a pressing bar, but; rotates as the last sheet of paper is engaged and moved. It thus results that the rotation of the roller D, which may be continuons or intermittent as desired` causes the sheets to be fed one after the other. There are ordinarily several sheets of paper projecting into the shield during normal rnnning. The number of such sheets varies with the thickness of the paper and the ad jnstments. Frequently three. or four, or more sheets thus project into the shield. but only the sheet nearest the feed roller escapes from the shield. This ability of the shield to take care of several sheets of paper ob-V riates the necessity of tine adjustment and of continuons readjustment for different thicknesses of paper. The mechanism per? ates- I'apidly, and with the desired precision.

and there is' nothing about it to get ont of order.
