JOI-IN W. GUYNES, OF OALVERT, TEXAS.

HAY-PRESS.

Specicaton of Letters Patent.

Patented Mar. 15, 1910.

To all 'whom it may concern:

Be it known that I, JOHN W. GUYNES, a citizen of the United States, residing at Calvert, in the county lof Robertson and State of rIexas, have invented a new and useful Improvement in Hay-Presses, of which the following is a specification.

My invention relates to new and useful improvements in hay presses.

The object of the invention is to provide a hay press comprising an elevated baling chamber', a press head operating vertically and a lever operating mechanism when the bale may be formed without undue exertion on the part of operators.

Another object resides in a novel press chamber construction and fastening means for the top and sides thereof, together with particular forms of lever connections and retaining devices for the press head.

Finally the object of the invention is to provide means of the character described that will be strong, durable, ecient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out oforder.

Vith the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this specin fication and illustrated in the accompanying drawings, wherein:

Figure l is a plan view or the press showing the sides of the press chamber open, Fig. 2 is a side elevation with the press chamber closed, Fig. 3 is a vertical section through the upper portion of the press with the top door raised and the levers at opposite ends of their stroke, Fig. 4 is an elevation with the parts as shown in Fig. 2, Fig. 5 is a detail of press chamber side fastening, and Fig. 6 is a detail in vertical section showing a modified form of the lever elevating mechanism.

In the drawings the numeral l designates a vertical press box mounted on a suitable base 2. At the Lipper end of the press box a baling chamber 3 is formed. At each end and centrally the box is provided with vertical slots 4 through each of which an arm 7 fixed to a press head 5 projects. The slots extend upward from the base to the bottom of the baling chamber; while the press head is free to be moved up and down in the press box. At the bottom of the baling chamber` parallel horizontal beams 6 are secured, one to each side of the box and project some distance beyond each end of the box as shown in Figs. l, 2 and 3. Near each end of the beams, a cross bar 8 is fastened. On each of these bars, a truss support 9 is mounted, being connected at its upper end with the outer ends of parallel braces l0 extending horizontally inward to the end of the press box to which they are secured. Plunger rods 11 extend vertically from the arms 7, with which they have pivoted connection, up between the braces which form a guide for the rod at each end of the box. Non mally the press head 5 rests in the bottom of the press box as indicated in Fig. 2, and the rods terminate just above the braces. When the press box has been filled with the material to be pressed, as will be hereinafter described, the pressing operation is carried out by elevating the press head in the box and pressing the material in the baling chamber to form the bale.

lThe means for elevating the press head comprises opposed levers l2 of suitable length and suspended a short distance from their inner ends by pivot links 13 pivotally supported from the upper central portion of the truss supports 9. This manner of suspending the levers gives a great leverage and enables the operators at the outer ends to exert considerable power on the inner ends when the levers are swung. Each lever at its inner end has pivotal connection with a collar 14 surrounding the adjacent plungerl rod and an inner diameter slightly greater than the diameter of the plunger rod. It is obvious that as long as the collars remain horizontal, they slide on the rod, but when the collar is rocked or tilted on the rod, owing to its larger diameter, the upper edge on one side and the lower edge on the opposite side will bite into the rod, thus taking a hold or binding on the same. IV hen either lever is swung down, the collar connected to the inner end thereof is tilted and binding on the rod, continued downward movement of the lever raises the rod. `When the lever reaches the end of its down swing, it is swung upward to begin a new stroke. When the upward swing is begun the collar is tilted back to a horizontal position, the lever swinging on its pivot link 13. This permits them to freely move up the rod without binding. However to accomplish this last movement and hold the press head in the position to which it is elevated, a dog 15 having an internal diameter like the collar, is engaged about each rod above the collar 111 and pivotally supported from between links 16 pivotall'y supported from the braces 10. When the collars 1l` are moved down the downward pull of the rods 11 tilts the dogs causing them to bind about the rods and hold them and the head 5 against downward movement. Any upward movement of the rods will break the binding act-ion and permit the rods and press head to be freely carried upward. The operator on each lever swings the lever thus elevating the press head intermittently until it reaches the bottom of the baling chamber and the arms 7 contact with the top of the slots 4f. lVhen the parts have reached this position the bale will be formed and is ready for tying and removing from the press.

The sides 17 of the baling chamber 3 are mounted at one end on strap hinges 18, which hinges al-so brace the box. Near its free end and at the central portion each side is provided with a wear plate 19 adapted to be engaged by the tapered inturned ends of a fastening bail 20 pivoted across the end of the chamber and provided with an upstanding lever 21, which when swung outward rocks the ends of the bail out of engagement with the plates and releases the sides. The tapered ends of the bail force the sides into close contact with end of the press chamber when closed.

The top 22 of the baling chamber is hinged at the same end as the sides being braced across the upper side by a transverse bar 23. On cach side of the bar metal plates 24. are secured, said plates terminating at the free end of the top in hooks 25 projecting over and a short distance down the face of the end of the baling chamber. These hooks are engaged by the looped portions of fastening bail 2G pivoted across the end of the baling chamber and having an upstanding lever 27, which when swung down rocks the bail out of engagement with the hooks, the looped portions straddling the plunger rods. At their opposite ends the plates 241 are connected to a hinge member 2S secured to the end of the baling chamber. One of the plates is extended to form a lever 29 by which the top may be swung. The surface of the press head and the under side of the top are provided with groovesl 30 to receive the tying wires.

In iillinp' the press the top is swung upward, the `lever 29 acting as a stop by contacting with the end wall of the baling chamber'. One of the sides may be left open until the loose material reaches up to the bal-ing chamber. After the press has been filled, the sides and top are closed and fastened and the baling operation as before described, carried out. After the bale is formed, the top and sides are released and swung open and the bale tied and removed. Before the next bale can be formed the press head 5 must be lowered which is acco1n plished by lifting up the collars and dogs to a horizontal position, releasing the plunger rods and allowing the press head to freely slide down to the bottom of the Ipress box by its own weight.

In Fig. 6 I show a modified form in which the plunger rods 11 are each provided with teeth 31 vadapted to be engaged by lugs 32 and 33 carried on the collar 111 and dog 15 respectively; otherwise the parts are the same.

I wish to call attention to the fact that by employing opposed levers and two operators, material may be baled by hand without a great amount of labor and expeditiously and by reason of the leverage had by the lever arrangement considerable pressure may be placed upon the bale. Also that the operation is quick, simple and easy.

It will be noted that as the levers 12 are operated and the press head moved upward, the latter will be brought to a stop when the arms 7 reach the upper ends of the slots 4, thus indicating to the operators that the pressing operation has been completed and preventing further operation of the levers until the head is lowered.
