POWER MOVEMENT FOR PRESSES.

SPECIFICATION forming part of Letters Patent No. 243,399, dated June- 28, 1881.

Application filed May 14, 1881.

To all whom it may concern Be it known that I, GEORGE A. PORTER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Power Movement for Presses for the Purpose of Pressing Cotton, Hay, &c., of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improved means of transmitting power to the screw of a press; and it consists, essentially, in the combination, with said screw, of anut provided with a wormgear, a worm-shaft engaging said gear and provided with a friction-wheel and a belt-pulley, the driving-shaft mounted in a sliding box and provided with a friction-wheel and abeltpulley, a belt connecting said pulleys, and a lever or other suitable device connected with the sliding box for the purpose of shifting the driving-shaft, and by the resultant change in the position of its friction-wheel and belt-pulley in relation to those of the worm-shaft reversing the motion of the screw, all as hereinafter more fully described.

In the annexed drawings, Figure l is a front view of a power-press provided with my improvements. Fig. 2 is a side view of same with a piece of the frame broken away to better illustrate the connection of the screw with the nut which operates it. Fig. 3 is a view of the actuating mechanism of the press, taken on the line m w in Fig. 1; Fig. 4, a plan view taken on line y y; and Fig. 5 is a vertical section of the nut, showing the detail construction of same and its connection with the screw, pressframe, and worm-shaft.

Similar letters of reference indicate corresponding parts.

A represents the hopper or case in which to place the hay, cotton, or other substance to be pressed, said case being supported by a suitable upright frame, B, adapted to firmly hold the cover on the case. The bottom of the case is movable and constitutes the follower of the press.

S denotes the press-screw, having its upper end fixed stationary in a socket or step, 8, properly secured to the follower.

N represents a nut fitted to the screw S, and

(No model.)

having a cylindrical body, a, by which it is journaled in a box, on, secured to cross-beams E E of the press-frame, as best seen in Fig. 5 of the drawings. One end of the nut N is provided with a worm wheel or gear, a, which is rigidly secured or cast thereon. The wormwheel'a is operated by a worm-shaft, b, journaled in suitable bearings, f f, on the pressframe, and having fixed to its extremity a friction-wheel, c, and a belt-pulley, d.

D denotes the driving-shaft, arranged parallel to the worm-shaft, and provided at one end with a driving-pulley, h, and at the opposite end with a friction-wheel, c, and a belt-pulley, e, which latter is connected with the pulley d of the worm-shaft by a belt, '1'. That end of the driving-shaft which carries the frictionwheel 0 and belt-pulley e aforesaid is mounted in a box, c, which slides in guides a secured to the press-frame, as shown in Figs. 3 and 4 of the drawings. By means of a pivoted lever, Z, connected with the box '11, the latter can be moved back and forth in the guides to, thereby swinging the end of the shaft mounted therein toward and from the worm-shaft.

The two friction-wheels c and c are of such diameters as to cause them to be brought in contact with each other by the approach of the driving-shaft, and the belt 1" is of such a length as to allow the driving-shaft suflicient play to disengage the two friction-wheels aforesaid and simultaneously tighten the belt. Since the direct contact of the two friction-wheels causes said wheels to rotate in contrary directions, while the belt-connection drives the two 8 5 pulleys in one direction, the shifting of the drivin g-shaft and resultant ch an ge in the transmission of the motion, as before described, reverses the motion of the nut N and screw S.

The friction-wheels are used for imparting a go pulley, and the lever I, connected with the slidin g box 0), all combined and operating substantially as shown and set forth.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 10th day of May, 1881.

GEORGE A. PORTER.
