T0 to whom it may concern:

Be it known that we, AUGUST ZILLER and HENRY BOUOHARD, citizens of the United States, residing-at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Hay- Presses, of which the following is a specification.

This invention has relation to presses having a rebounding and intermittently-operated plunger, and aims to provide a novel and fication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which 7 Figure 1 is a perspective view of a press embodying the invention. Fig. 2 is a side view, a portion of the baling-chamber and the hopper being in section. Fig. 3 is a section on the line X X of Fig. 2, showing the parts on a larger scale and the sweep disconnected from' the driver. Fig. 4 is a perspective view of the slide-frame, driver, and mountings therefor. Fig. 5 is a detail view showing a modification. Fig. 6 is a transverse section of the baling-chamber about on the line Y Y of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The component parts of the press are preferably mounted upon opposite ends of a bed or base 1, consisting of a board or plate and comprising a baling-chamber and operating means for the plunger. The baling-chamber is indicated at 2 and may be of anyconstruction and consists of inclosing'walls and a series of strengthening and bracing frames, the latter comprising lower transverse sills,upper cross-bars, and uprights connecting the sills and cross-bars and bracing the side walls of the chamber. The hopper 3 is located at the innerupper end of the baling-chamber and receives and directs the charges to the balingchamber in the operation of the press. The upper side or wall 4 of the baling-chamber is pivoted at its inner end and is adjustable at its outer end by means of a set-screw 5, threaded into the cross-bar of the rear bracingframe. A retainer is located immediately in the rear of the hopper and is pivoted or hinged to the crossbar of the intermediate bracingframe and consists of a plate 6 and a down- Wardly-extended lip 7, beveled upon the side adjacent to the hopper, so as to admit of the charge passing readily by the lip in the operation of the press. A cleat 8 is applied to the upper side of theplate 6, adjacent to its free end,and projects beyond the sides of the baling-chamber and is connected at its ends to the latter by springs 9, which are of a strength to force the lip 7 in the rear of the charge after the same has cleared the lip in the forward movement of the plunger. Other retainers 10 are applied to the sides of the baling-chamber and consist of flat springs secured at one end to the side walls of the baling-chamber and having the opposite end flexed so as to extend into the baling-chamher and across the path of the charge, so as .to cooperate with theupper retainer or lip 7 and prevent the charge from following the plunger upon its return stroke.

The plunger or follower 11 is adapted to reciprocate below the hopper 3, and its stem 12 is provided at its outer end with a rectangular slide-frame .13, held in place and directed in its movements by four posts 14, projected upwardly from the bed or plate 1, said posts having notches 15 in their outer sides to receive the longitudinal bars of the slide-frame 13, so as to retain the same in position against casual displacement. A plate, strip, or board 16 extends crosswiseof the bed 1 and slide-frame 13 and is secured to the upper ends of the posts 14: and is provided at its ends with cams 17, facing in opposite directions and adapted to unship the sweep 18 from the driver 19 at proper and determinate points in the revolution of said sweep.

The operating means comprise a shaft 20, driver 19, sweep 18, clutch between said sweep and driver, and a flexible connection 21, the latter being attached at one end to the driver 19 and at its opposite end to the outer crossbar of the slide-frame 13. The sweep is provided with a tube 22, pendent therefrom and journaled in the plate or part 16 and provided at its lower end with a half-clutch 23. The tubular bearing 22 is secured to the sweep in any substantial way and is provided at its upper end with an outer flange apertured to receive the fastenings employed for attachment thereof to the sweep. The shaft is journaled at its lower end in the bed 1 and its upper end in the tubular bearing 22 and is secured to the driver 19 so as to rotate therewith. A plate 24 is secured in any substantial manner to the lower end of the shaft 20 and underlaps the bed 1 and serves to prevent vertical displacement of said shaft,while at the same time admitting of free rotation thereof. The driver 19 is preferably of wood, although this is not essential, and its peripheral portion is grooved to insure seating of the flexible connection 21 to efiect rectilinear movement of the plunger 11. A tube is secured to the driver, and its upper end is provided witha half-clutch 26 for cooperation with the half-clutch 23 in the manner presently to be explained. The lower end of the tube 25 is flanged to space the driver upon the bed and alsoto receive the fastening means connecting the-tube 25 with the driver 19. The sweep 18 may be operated by hand, horse, or other power and is mounted upon the shaft 20 and within the plate 16,- so as to receive a combined rotary and np-anddown movement, the latter being essential to admit of unshipping of the sweep from the driver inorder to permit a rebound of the plunger after compressing the charge and to .admit of a new charge being supplied to the baling-chamber. The rebound of the plunger is eifected by means of a spring 27, which is connected at one end to the stem 12 and at its opposite end to the plate 16. The spring 27, which is of the coil type, is expanded as the plunger is driven forward, and the instant the driver is released from the impelling means the spring contracts and returns the plunger to a normal position. The sweep is forced downward to hold the half- clutches 23 and 26 in engagement by means of a spring interposed between it and the shaft 20. In the preferable construction the spring is of bow form, as shown at 28, and is secured at a central point to the shaft 20 by means .of a headed fastening 29, the end portions of the spring exerting a downward pressure upon the sweep at opposite sides of the shaft, whereby the sweep is held level and in clutched engagement with the driver in the manner stated. In the construction shown in Fig. 5

the spring 30 is of the coil type and surrounds the upper portion of the shaft 20 and is confined between a washer and the sweep.

In the operation of the press the sweep 18 is rotated and eifects a corresponding rotation of the driver 19 through the instrumentality of the interposed clutch, and as a result of this operation the flexible connection 21 is wound upon the driver and the slideframe 13 is moved inward and forces the plunger into the baling-chamber, whereby a compression of the charge supplied to said baling-chamber through the hopper is effected. When the sweep alines with the plate 16, it receives an upward movement by riding upon the cams 17, thereby unshipping the half-clutches and disconnecting the sweep from the driver, whereupon the spring 27 returns the plunger to a normal position in the manner stated. As soon as the sweep clears the cams in its further movement it is moved downward by either the spring 28 or spring 30 or like means, thereby permitting the sweep to again become clutched to the driver, when the operation just described will be repeated. In the construction shown the sweep is disconnected from the driver twice during each complete revolution. The cams and parts of the sweep coming in contact with said cams are protected, so as to resist wear, or, as shown in Fig. 5, a roller 31 may be applied to the under side of the sweep to come in contact with and ride upon the cams,there by reducing the friction and resistance to a minimum amount.

Having thus described the invention, what is claimed as new is 1. In a press, and in combination with the baling chamber, and plunger, operating means for said plunger comprising a shaft journaled at its lower end, a driver journaled to said shaft, a cam-plate, a sweep journaled in said cam-plate and forming a bearing for the upper end of the aforementioned shaft, a clutch between the sweep and driver, and connecting means between the plunger and driver, substantially as set forth.

2. In a press, and in combination with the baling-chamber and plunger, a shaft, a driver journaled to the shaft, a cam-plate,- a sweep journaled to the cam-plate and forming a bearing for an endportion of the aforementioned shaft, a clutch between the driver and sweep, and a spring confined between the projecting end of the shaft and sweep to normally hold the parts of the aforesaid clutch in engagement, substantially as described.

3. In a press, and in combination with the baling-chamber and plunger, a slide-frame connected to the stem .of the plunger, posts notched in their outer sides to receive the 1ongitudinal bars of the slide-frame to hold the latter in place and direct it in its reciprocating movements, a cam-plate secured to said posts, a sweep journaled to the cam-plate, a shaft journaled at one end to the sweep and at its opposite end to the bed of the press, a driver journaled to the shaft, a clutch having its component parts applied, respectively, to the driver and sweep, a spring for effect ing a rebound of the plunger, and a. flexible connection between said plunger and driver, substantially as specified.

In testimony whereof we aflix our signatures in presence of two witnesses.
