PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,844, dated March I5, 1898. Application filed February 27, 1897. Serial No. 625,346. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN H. RUssELL, of Amsterdam, in the county of Montgomery, in the State of New York, have invented new and useful Improvements in Paper-Feeding Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to paper-feeding machines; and the object is to provide suitable and efficient means for automatically feeding thick paper, as pasteboard or strawboard, to the folding apparatus of paper-boX-making machinery.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a side elevation of my improved paper-feeding machine. Fig. 2 is an end view of the same, looking from right to left of Fig. 1.v Fig. 3 is atop plan view of the machine. Fig. 4 is a sectional view taken on line no a: of Fig. 3. Fig. 5 is a detail view, and Fig. 6 is a sectional view taken through the center of the cross-bar.

Referring specifically to the drawings, A is a table, having four legs a a and a a. Near one end of the table, below the surface and extending transversely across'the same, is the driving-shaft B. Mounted on the center of this shaft to turn with it is a large roll or cylinder 0, having a central peripheral groove therein for a small roller, to be hereinafter referred to. The periphery of this roller extends slightly above the surfaceof the table and may be covered with felt.. Abovethe.

roll O is a smaller roller O, which has its ends fulcrumed in yielding bearings working in brackets c a, mounted on the sides of the table. I) b are coil-springs above said bearings, and o c are adjusting-screws passing through the brackets c c and bearing upon the springs to regulate the pressure of the roll 0 upon the paper passing between the rolls 0 and O.

A sprocket-wheel D on the shaft B serves to drive the shaft at the proper speed, depending upon the speed of the folding apparatus. Another smaller sprocket-wheel E on the same shaft is connected by a chain E with a large sprocket-wheel F, keyed to a shaft F turning in bearings adapted to slide in dovetailed grooves in a pair of rails G G,

secured at their endsto the legs of the table.

The chain connecting the sprocket-wheels E and F is loose or of sufficient length to allow the shaft F to be moved a greater distance from the shaft E to accommodate longer sheets of paper or board when necessary.

Mounted on the shaft F, near its center, are a pair of large narrow rollers H H, separated from each other. Theserollers extend a considerable distance above the top surface of the table and haveat diametrically opposite points on their peripheries transverse inclined ribs d, which are stationary on the rollers, and back of these adjustable ribs 6 are springs which serve to strike the edge of the paper or board sheet as the rolls revolve and carry it forward between the rollers O and C, which feed said sheet to the folding apparatus. (Not shown.) The rear end of the pile of paper-boards P is raised by the rolls to an inclined position, and the stationary ribs d on the rolls serve to insure the catching of the adjustable ribs against the rear edge of the lower board even if it be somewhat warped, as it is liable to be. For instance, should the rear edge of the lower sheet be warped these inclined ribs 01 will tend to raise the depressed portion of the edge and to straighten it. By simply turning the adj llSiJlHg-SCIGWS f f more or less the adjustable ribs may be moved toward or from the periphery of the roll, de-

pending upon the thickness of the sheets of paper P.

In order to provide a smooth inclined surface for the paper, a frame I, having three parallel longitudinal plates joined together at their ends, is hinged below the surface of the table between the rolls H and (J and held at the other end above the table by a screw 6, passing through the table and bearing upon its lower side. By means of the screw the inclination of the frame I may be varied as desired. The large rolls H H are moved toward and from the roll 0 by means of a screw J, connected with the shaftF between the rolls H H and passing through a cross-bar K, extending between the legs a. a and a wheel h on the screw fulcrumed in said bar.

By locating the feeding-disks or large rolls' II II with their peripheries extending above the point of contact of the feed-rollers and also above the frame I the ribs 6 on the disks can easily catch the edge of the lower sheet when in its inclined position on the frame. When the sheets are inclined with their rear edges raised, the lower sheet can be moved more easily by the rolls H H, and this arrangement necessitates the raising of the peripheries of the large rolls.

L L are parallel side guides for the paper, mounted upon the top of the table and adj ustable toward and from each other by means of a transverse screw-shaft M below the top of the table, said screw-shaft having right and left thread-engaging studs mm, extending downward from the said guides. The studs m m pass through slots 2' i in the top of the table. The screw-shaft M is turned by means of a small wheel n on the end of the shaft at one side of the table.

Between the roll 0 and the front ends of the guides L L is an upright board N, secured at its ends to the table. This board has its lower edge cut away to provide a passage for the lower sheet of paper when it it forced forward by the large rolls H H. Said board N is cut away to accommodate the thickest sheets that may be fed, and in order that this passage may be closed more or less I provide an adjustable sliding board or gate R, which may be raised or lowered, as desired. Said gate slides between two vertical ribs 1" r, secured to the board N. A screw j projects from the gate through a small slot is in the board N, and upon the end of the screw and bearing upon the opposite side of the board is a thumb-nut Z, which secures the gate in position. The lower end of the gate is beveled, as shown in Fig. 4, so that the sheet of paper may be more easily passed through even if somewhat warped.

Directly below the board N, below the surface of the table but projecting slightly above the same, is a small roller .9, fulcrumed in suitable bearings. This roller decreases the friction at the commencement of the movement of the lower sheet of paper. Said roller .9 is located in the groove in the center of the roll 0.

The sheets of paper to be fed are out to the same size and placed upon the inclined frame of the table, with their front edges bearing against the gate R. The side guides are then moved together to hold the sheets in place loosely. The rolls H H are moved so that the shaft F is directly below the rear edges of the sheets P. When in operation, the rolls H H will catch and carry successively the lower sheet to and between the rolls 0 and C, and these rolls carry the sheets to the folder of the box-making machine. Small rollers may be set in the plates of the frame I to decrease friction.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a paper-feeding machine, the combination with the table and the guides, of horizontal feed-rollers between which the sheet is passed, large rolls having catches on diametrically opposite sides, said rolls having their peripheries extending above the point of contact of the feed-rollers, and means to move the large rolls toward and from the feed-rollers, substantially as described.
