HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 305,163, dated September 16, 1884.

Application filed August 1, 1884. (No model.)

To all whom it may 0072100772,.-

Be it known that I, GEORGE W. DUNN, a citizen. of the United States, residing at Morning View,'in the'county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Hay-Presses; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will "enable others skilled in the 'art to which it appertains to make and use the same.

This invention relates to that class of upright baling-presses which are adapted for hay, cotton, hemp, flax, and the like, and which employ 'a gravity-plunger connected I 5 with and elev ated by horse-power mechanism.

The object of my improvements is to provide a simple press of this class which will possess advantages in point of inexpensiveness and durability of construction and convenience and general efficiency in operation.

In the drawings, Figure 1 is a perspective view of myimproved press. Fig. 2 is a side elevation ,of the same. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is a vertical transverse sectional view. Fig. dis a detail sectional view.

Corresponding parts in the figures are de noted by the same letters of reference.

Referring to the drawings, A A designate 0 the horizontal sills of the press, which are connected and braced by cross pieces B, and support at oneend the upright frame. This framecompr-ises four uprights, O, which are united and braced at their top ends by cross- V 3 5 pieces D, and at the top of the frame are provided bearings for a horizontal shaft, E, carrying a fixed pulley, F, over which the rope Gpasses. The inner end of this rope is connected to the plunger H, while its other end 0 is secured to a drum, 1, fixed upon a shaft, J, having its bearings upon the sills A A. One end of this shaft carries a pinion, K, adapted to engage with as'egmental rack, L, fixed upon the rear end of a horse-power sweep, M, which preferably comprises a main bar, N, carrying a clevis, O, to which is connected a singletree, P, the rear end of the said bar being bifurcated to form divergent arms a a, between which is secured a pivot block or plate, Q,

" through which the pivot-pin R passes and enters the sill S of the horse-power frame. To the ends of the arms a n is preferably secured a segmental strip or plate, T, arranged under the and T. A horizontal platform, V, is preferably comprised in the horse-power frame, and the said frame is connected to one of the sills A by means of cross-beams XV, extending from the same to the sill S of the horse-power.

From the foregoing arran gement it is apparent that as the sweep is operated by the horse, and its segmental. rack meshes with the pinion K, the shaft J is revolved to cause the rope G to wind upon the drum and elevate the plunger. Then, when the rack has passed out of engagement with the pinion and to the other side of the same, the plunger is permitted to drop by its own gravity. The horse is then turned and driven in an opposite direetion, when the rack again engages the pinion, and causes the latter to turn in an opposite direction and again effect the elevation of the plunger. The segmental rack preferably forms a quadrant, whereby four beats of the plunger are effected by a movement of the sweep equal to one complete circle.

X designates a swinging beam, which is secured at its lower end to a shaft, Y, having bearings upon uprights E E. The top end of the said beam is provided with a slot, 00, in which is j ournaled a pulley, Z, over which the rope G passes to the drum, the office of the said beam being to takeup the slack of the rope as the plunger falls. The top end of the swinging beam is drawn against the pulley F during the elevation of the plunger, whereby it is adapted to act as a brake upon the said pulley to obviate premature dropping of the 5 plunger, the said end being preferably curved, as shown at x", to adapt it to the periphery of the pulley.

A designates the bale box, which has an open top, and comprisesa bottom, B seated 10o upon the sills A A, vertical sides 0 secured to crossstrips 6-, extending between the uprights 0, and a vertical end strip, D secured also between the uprights O, as shown. The bale-box is-adapted to receive the plunger, which corresponds to the boX, and is preferably rectangular, and moves, when out of the box, within vertical guide-strips a", formed or provided upon the uprights C. One end of the bale-box is formed by a hinged door, E through which doorway the bale may be removed after it is pressed. The said door is secured firmly in position during the operation of the plunger by means of a pivoted cross bar, F engaging a pin or staple, G or by any other suitable fastening means.

Above the door E is provided a feed-door, 1-1, which is hinged or pivoted at its lower end upon a cross bar, 1 and is provided at its top with a crossbar, J adapted to limit its inward movement. This feed-door is adapted to swing downwardly and outwardly by its own gravity, and to facilitate this movement it may be provided with a weight, K at its top. The door is automatically closed by means of a cord, L-, secured to the crossbar J passing over a pulley, M upon one of the uprights O, and from thence passing down be-' tween two pulleys, N N journaled in a slot, 0 in a beam or bracket, P extending from one of the crosspieces O, the lower end of the cord being connected to the rear end of the sweep. By this arrangement, as the rack upon the sweep meshes with the pinion and the plunger is elevated, the feed-door automatically opens until theplunger has passed above it and the rack has performed about half of its full movement, when, during the continued movement of the rack, the sweep draws upon the cord, and thereby effects the closing of the feed-door before the rack passes from under the pinion and the plunger falls.

Q designates slots or kerfs in the end strip, D through which cords or bands may be passed to secure the bale. Corresponding slots, R are formed in the bottom of the door E and grooves are provided also in the bottom of the plunger, as shown at S T designates a block pivoted upon one of the uprights G, and provided with an operating arm or handle, U", by which it may be set over the top edge of one of the vertical sides of the bale-box and serve to support the plunger while the baleis being removed, or at any other desired time. hen the plunger is again elevated, this block is adapted to drop down by its own gravity from position for engagement with the plunger.

I claim as my invention and desire to secure by Letters Patent 1. The combination of an upright frame embodying a bale-box at its bottom, a pulley at the top of the frame, a plunger, a shaft carrying the pinion and a drum, the rope con- 6 5 nected with a plunger and secured to the drum, and the sweep carrying a segmental rack adapted to mesh with the pinion, substantially as set forth.

The combination of an upright frame embodying a press-box at its bottom, apulley at the top of the frame, the shaft carrying a pinion and a drum, the plunger, the rope connecting the plunger and the drum, the sweep carrying the segmental rack, and the swinging beam hinged to the upright frame and carrying a pulley engaged by the rope carrying the plunger, substantially as set forth.

3. The combination of an upright frame comprising the press-boX, the pulley at the top of the frame, the horizontal shaft carrying a pinion and a drum, the plunger, the rope for elevating the same, the semicircular guide-plate terminating in stop shoulders, and the sweep moving over said plate, and provided with a rack-quadrant adapted to mesh with the pinion, substantially as and for the purpose set forth.

4. The combination, in a press embodying a gravity plunger and means for elevating the same, with the elevating-cord, of aswinging beam engaged by the same and adapted to take up the slack, substantially as and for the purpose set forth.
