HAY-PRESS.

SPECIFICATION forming part of Letters Patent .N o. 670,421, dated March 26, 1901. Application filed September 11, 1900. Serial No. 29,671. (No model.)

To all?, whom t may concern:

Be it known that I, ROBERT D. EMMoNs, a citizen of the United States, residing at Meridian, in the county of Lauderdale and State of Mississippi, have invented a new and useful Hay-Press, of whichthe following is a specification.

This invention relates to presses in general, and more particularly to that class employed in baling hay, straw, &c., the object of the invention being to provide a construction in which a maximum compression will be secured with a minimum of energy applied and in which, furthermore, the plunger will be released and returned after each operation and in which the ends of the straws will be tucked into the press to form a neat bale.

Additional advantages and objects of the invention will be evident from the following description. v

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view showing the complete baling-press in its operative position. Fig. 2 isa central longitudinal section of the press. Fig. 3 is a plan View showing the toggle-levers and their operating means.

Referring now to the drawings, the press comprises a boX,including a base 5 and sides 6 and 7, the rear portions of the sides being slotted, as shown, and which is the usual construction, this slotted portion having a top 8. Cross-braces 9 are secured to the under side of the box, and additional braces 10 are disposed transversely of the upper side thereof, these braces being perforated for the reception of the usual tie-rods 11, there being employed also the usual vertical braces 12, having tie-rods 13 at their ends.

Between the foremost cross-brace 9 and the one in the rear thereof is the hopper, through which the material to be baled is contributed to the press, the front edge of the hopper being formed by the rear edge of a top portion 14 for the front end. of the press-box.

A plunger or piston 15 is disposed within the press-box and is provided with a rod 16,

which is operated in a manner hereinafter described to perform the pressing operation.

To provide for tu cking the ends of the straw or hay into the press, atucker is arranged at the rear side of the hopper, this tucker consisting of a board or plate 16', fixed upon a shaft 17, which is rotatably mounted in the sides of the press-box in such a manner that when the tucker is in a vertical plane its side kabove the shaft 17 will lie against the front lit pivotally, causing the upper edge thereof to move downwardly and tuck the ends of the straws and hay into the press-box, the upper end of the plunger being cut away at its forward portion to receive the tucker and to permit sufficient space under it to allow thetucked ends to be drawn from under the plate as the plunger is returned. When the plunger is withdrawn, the tucker returns to its former position.

The plunger-operating mechanism is'mounted at the outer end of a sill 20, which may be attached to or formed integral with the base of the press-box, and it consists of a pair of toggle-levers, one of which includes links 21 and 22 and the other of which includes links 23 and 24. The links 22 and 24 are pivotally connected by means of a pivot-bolt 25, which is engaged with the sill 20 and is braced at its upper end. above the links by a metallic strap 26, as shown. The links 21 and 23 are pivotally connected by a bolt 27, which engages the plates 29 and 30 above and below the links and'which are secured to the upper and lower faces, respectively, of the plungerrod, the several links being halved at their ends in order that they may all lie in a common horizontal plane.

In order to operate the toggle-levers, a windlass-shaft 31 is rotatably mounted in the ,sill 20 and-within the inclosure of the levers, which shaft has the usual sweep 32 fixedto its upper end, while a winding-drum 33 is mounted loosely on the shaft and in the plane of the toggle-levers, this drum having at- IOO tached to its periphery at diametrically opposite points the ends of chain- sections 34 and 35, the opposite ends of which are connected with their respective toggle-levers, so that as the drum is rotated the chain-sections will be wound thereon and the toggle-levers will be operated to advance the plunger` for the compressing operation. When the plunger is released, it is returned by a helical spring 3G, which is attached at one end to the plungerrod and at its opposite end to the sill.

To alternately rotate and release the winding-drum, so that it may have an oscillatory movement, a latch 40 is pivoted upon the upper end of the drum and is limited in its pivotal movement in one direction by means of a pin LIl upon the upper end near the edge of the drum, the latch being held normally against the pin by means of a helical spring 4t2, attached 'at one end to the drum and at the other to an arm 3, extending at right angles to the latch and from a point at the opposite side of the pin from the fulcru 1n of the latch. The opposite end of the latch, which projects inwardly of the drum, has an engaging hook 4A, and this hook engages alternately with the ends of a double arm 45, which is fixed upon the shaft 31. In the path of movement of the opposite end of the latch is a plate or lug 45', mounted upon the link 24, and when the latch strikes this lug it is moved on its pivot to release the engaged end of the arm 45.

The operation of the plungeroperating mechanism is as follows: The parts being in the positions shown in Fig. l, if the outer end of the sweep is moved to the left the engagement of arm 45 with the latch-hook will cause the drum to rotate with the sweep and wind the chains 3a and 36 upon the drum, thus drawing the togglelevers inwardly and projecting their ends to move the plunger forwardly. The lug 45 is so positioned that when the plunger is about to complete its forward movement the latch will strike the lug, and further movement of the drum causes the latch to swing upon its pivot and release the arm. The drum being then free of the shaft, pressure upon the plunger is released and its spring returns it, causing the sides of the toggle-levers to move outwardly and the drum to return to its former position. The opposite end of the double arm then moves into engagement with the latch and the plu nger is again moved forward, there being thus two operations of the plunger' for each complete rotation of the windlass-shaft.

The sweep is adapted for the attachment of a draft-animal thereto, as shown.

With this construction it will be seen that a great pressure can be applied to the compressing` operation and that the ends are properly tucked into the press-box; also, that the entire apparatus is simple and efficient.

In practice various modifications of the structure shown may be made, and any suitable materials and proportions may be used for the various parts, without departing from the spirit of the invention.

What is claimed isl. A press comprising a press-box and a plunger operable therein, a rotatable shaft provided with operating means, a drum upon the shaft, a toggle-lever connected with the plunger for operating it, a chain connected with the toggle-lever and with the drum to be wound upon the latter to operate the togglelever, a latch upon the drum for engagement with the shaft to rotate the drum therewith, and means carried by an element of the toggle-lever for engagement with the latch to operate the latter to release the shaft.

2. A press comprising a press-box and a plunger operable therein, a rotatable shaft provided with operating means, a drum on the shaft, a toggle-lever at each side of the drum and connected with the plunger, chains connected with the toggle-levers and with the drum to be wound on the latter, an arm fixed to the shaft, a latch upon the drum for engagement by the arm to rotate the drum, and means in the path of movement of the latch for moving it pivotally to release the arm and permit return movement of the plunger.

3. A press comprising a press-box and a plunger operable therein, a rotatable shaft provided with operating means, a drum mounted loosely on the shaft, a toggle-lever at each side of the drum and connected with the plunger, chains connected with the toggle-lever and with the periphery of the drum, an

larm fixed upon the shaft, a latch pivoted upon the drum for engagement with the arm to lock the drum to rotate with the shaft, a stop in the path of bodily movement of the latch to move it pivotally and release the arm, means for returning the plunger, an arm upon the latch and a spring connecting the latcharm and the drum and adapted to hold the latch yieldably in position for engagement by the arm upon the shaft.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ROBERT D. EMMONS.
