EDWARD DILL, OF SHELBYVILLE, INDIANA.

s'PEcIFrcATIo'N forming i95 Li To "all whom it they concern Be it known that I, EDWARD DILL, a itizen of the United States, residing at She yville, in the county of Shelby and State'rof 5 Indiana, have invented a new and useful Improvement in Cider-Presses, of which the following is a specification.

My invention relates to improvements in cider-presses in which a pair of reciprocating plungers operate in conjunction with a pair of reciprocating followers and the objects of my invention are, first, to provide a pair of strainer-cylinders with a pair of reciprocating plungers; second, to provide each strain-cylinder with a reciprocating follower or movable pressure-head third, to afford facilities for the discharge of the pulp after being pressed; fourth, to provide mechanism for moving the followers back into their respective cylinders after the pulp has been discharged. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top or plan View of the entire device. Fig. 2 is a longitudinal vertical sec- 2 5 tion of the same; and Fig. 3 is a view of part of the operating mechanism at one side of the machine, one side of the frame being removed to show the parts fully.

Similar letters refer to similar parts throughout the several views.

A A represent the two sides of the frame, and A A the end pieces. B, B, B B and B represent cross-pieces let into the side frames, A A. The sides A, ends A and cross- 3 5 pieces B are each made in two pieces and all united at the central joint, A Thus theframe is composed of a top and bottom half, as

shown.

The perforated pressing-cylinders O O are 0 provided with hoppers D, and each cylinder is securely fastened in the cross-bars B and B the bar B Fig. 2, being cut away around the cylinders, as at d, to permit the juice to freely pass out. Each cylinder is provided with a long piston, E, and the rear end of each piston is firmly attached to a yoke, P, and on the opposite side of the yoke P from thaton which the piston is secured is an extended guidebar, 1, which operates in suitable bearings formed in the cross-bar B as shown in Figs. 1 and 2. These yokes P are provided with etters Patent No. 233,333, dated October 19, 1880. Application '"led August 5. 1880. No model.)

slide-blocks n n, in which the cranks w w of the crank-shaft M operate, and by means of which the piston receives a reciprocating motion in an alternate manner.

The crank-shaft M is provided with two cranks, to w, diametrically opposite each other, and the shaft M, outside of each crank butinside of the frame A A, is provided with the ratchet-wheels R R, while the shaft M, outside of the frame, on one side, is provided with a wheel, L, which is also provided with acrankhandle, L, by means of which the crank-shaft M is revolved. either by hand or by the gearing of a grinding-mill, (not shown,) which may be located above the press, if desired.

The followers G are piston-heads fitting loosely inside of the cylinders (J 0. Each follower-head G is provided with a rack-bar,

G, which extends back and operates in suitable slides formed in the cross-pieces B B. The outer ends of each raek'bar G is provided with a pin or stop, I), to prevent the head G from entering the hopper part of the cylinders O 0. Between the cross-bars B and B, 7 and also between the sides A A and longitudinal bar B, are located two independent shafts, J. These shafts are provided with two spur-wheels each, one near each endthatis, the wheel H is secured to the shaft J near the side frame, A, while the wheel H is secured to the same shaft near the longitudinal bar B and immediately under the rack-bar G of the cylinder 0.

The shaft J is provided with a coil-spring, I, the end 43 being secured to the side of the wheel H, while the other end i rests against the cross-piece B. Thus, when the wheels H H are rotated so as to twist or wind up the spring I on the shaft J, the spring will exert a counter power and cause the wheels to rotate back when the force is removed that turned them forward.

At each side of the machine, on the inside of the side frames, A A, as shown in Figs. 2 and 3, are arranged rack-rods K. The rod K, Fig. 3, is provided with the rack K on its upper side, and this rack is held in gear with the wheel H by the guide '1, on which the rod slides freely. Above the rack K a short dis- Ioo tance the rod K is provided with a series of ratchet-teeth, m, in which the projecting lip of the lever 0 operates, as will be hereinafter described. The upper end of the rod K, on the lower side, is also provided with ratchet-teeth K which operate on the ratchet- 5 wheel It of the crankshaft M. Above the bar K is a spring, I, for holding the ratchet-teeth R in gear with the wheel It. The wheel Itis provided on its outer side with a pin or stud, s, which, as the wheel 1t revolves, strikes the end of the lever 0, carrying it downward, thus releasing the lip o from the ratchet m, the use of which will be hereinafter described.

A trough, U, with discharge-spout n, is located under the perforated cylinders to catch and conduct off the elder.

The operation of my device is as follows, to wit: The ground massis placed in thehoppers D D, and falls, by its own weight, into the cylinders (J C in front of each plunger as the plungers move back. The forward thrust of the plungers compresses the ground mass between the head of the piston E and head G of the follower, the follower G and its rackbar G being held forward by the spring I on the shaft J with sutiicient force to squeeze the juice out of the mass of ground apples before it commences its backward stroke. After the juice has been squeezed out of the mass, then the further advanee movement of the piston E and pulp forces the follower G and its rackrod G back until the pulp is entirely beyond the end of the cylinder. At the same time that the follower is driven back the rack G rotates the wheels H and II, causing the spring I to be twisted up together on the shaft J. At the same time the wheel II causes the rod K to move diagonally upward by reason of the cogs K, and the ratchet teeth K" slip over the ratchetteeth of the wheel R, at which point the lip 0 of the lever falls into the ratchetteeth at of the rod K, and hold the rod stationary and prevent the spring I from acting on the shaft J and wheels H ll,thus preventing the follower (x G from following the piston E back into the cylinder until after the pressed pulp a has been released and allowed to drop down from between the follower-head G and piston-head E. As the wheel I. and cranks w to still continue to rotate the pin .s' on the wheel It strikes the lever 0, causing the lip 0 to be released from the ratchet m. At the same time the spring 1: forces the ratchet-teeth K of the rod K into gear with the teeth of the wheel R, thus preventing the spring I from revolving the wheels H H and throwing the rod K violently back, but allows the rod K to be carried back as the crankshaft and wheel R are revolved, the spring I aiding the movement and the wheel H carrying the follower forward into the cylinder, where the same operation is again repeated.

It is obvious that the two plungers E E and the two followers act in alternate manner, thus forcing a double-acting continuous press-that is, while one piston is squeezing out the juice the other piston is going back to allow more material to be fed into the cylinder in front of it for pressure.

WhatI claim as my invention, and desire to secure by Letters Patent, is-

1. In a cider-press, the combination of the cylinder 0, the piston E, the followers G with rack-rod G, the wheels H H, the shaft J, the spring I, the rod K, with rack K at one end and ratchet K at the other end, with ratchet 121 near its middle, the lever 0, with lip 0, the wheel It, with its pin .9, and the crank mechanism, substantially as shown and described.

2. In combination, the wheels H H, the spring I, the rod K, the spring 11, the wheel It, the pin 8, and lever O, as and for the purpose specified.

3. The combination of the piston E, the follower G with rack G, the wheels H H, the shaft J, the spring I, whereby the wheels H H are rotated and the spring I wound up as the follower is forced back, as and for the purpose specified.

4. The combination of the rod K, the wheel 11, the lever 0, the ratchet-wheel R, and pin 8, whereby the wheel H is prevented from revolving back until the lever O is tripped by the stud s, and the wheel H revolved by the rotary movement of the wheel R, aided by the spring 1, substantially as shown and described.

In testimony whereofl have signed my name to this specification in the presence of two snbscribin g witnesses.

EDWARD DILL.
