HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 712,338, dated October 28, 1902.

Ap'lliimion flied Mmh 7, 1902. serial No. 97,075. (No model.)

To all whom, it Wawy concern,.-

Be it-known that I, TILDEN SHANK, a citizen of the United States, residing at Glass, State of Alabama,have invented anew and useful Improvement in Hay-Presses, of which the following is a specilication.

My invention consists of an improvement in hay-presses of a suitable body portion with a plunger moving therein and guides for said plunger and means for operating the same.

Figure l represents a plan view of a haypress embodying my invention. Fig. 2 represents a partial side elevation and a partial sectional view on line a; x, Fig. 1. Fig. 3 represents a partial sectional view on line y y, Fig. l. Fig. 4 represents a sectional view on line a a', Fig.- 2.

.Similar letters of reference indicate corresponding parts inthe figures. l

Referring to the drawings, A designates a hay-press having a box or frame which is of unusual construction and has the usual central opening therethrough in which is mounted and'guided aplunger-head D, to Which is pivotally attached a plunger-arm E, which latter is bifurcatcd at one end and has mounted therein a wheel F, which is journaled on a pin G, the ends of which project and on which are mountedv the rollers U. Pivoted at H to a suitable portion of the frame is a crank-arm J, which is provided with bifurcated ends K and L, whichare adapted to engage with the rollers U on the pin G when said crank-arm is properly'turned, the latter having a crank M thereon Vfor manipulation thereof. p

N designates a cam or quadrant which has the slot P therein in which the Wheel F is adapted to travel and is guided thereby.

Q designates a spring whichis suitably attached to the plunger-arm E and to the frame of the machine, said spring being adapted to return the parts to their Anormal position after operation.

R designates a bar which is mounted on the frame of the machineand which is suitably guided in slots in the' ears S, secured to the frame B, a spring T being adapted to return the said bar to its normal position after it has been moved therefrom.

In the sides of the frame B are the slots or openings C, in which are the elbow-arms V, which have the shoulders W, which project ,intothe interior of the frame B, said arms being connected with suitable springs A, which are adapted to hold the same normally in position, as shown in Fig. 4.

The operation is as follows: The hay or other material is placed Within the casing and the crank M operated to turn the crank-arm J untiloneend-foreXample,L-contacts with the rollers U on the pin G, when the said crank-arm is movedin the direction indicated by the arrow. The plunger-arm E is forced in the direction indicated by the arrow, being guided by reason of the roller F moving in the slot P, which is in the quadrant N. This operates the plunger-head D to press the hay, andthe spring Q returns lthe plunger head and arm to their normal position, when the crank M is operated in the opposite direction, it being seen that when the hay is being pressed by the plunger D it will force outthe springs V through the opening C; but after the pressure on the arm V ceases the springs A will force in the arms V ,to the positionseen in Fig. 4, and the shoulder W will prevent the hay from springing back.

It willb evidentthat various changes may be made by those skilled in the art which will come within the scope of my invention, and

I do not, therefore, desire to be limited in every instance to the/exact construction as herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1 In a press,abody portion,a plunger-head, a plunger pivotally connected therewith and bifurcated at its outer end, a roller carried in said bifurcated end, a fixed quadrant embraced by said bifurcation and having a camslot in which said roller travels and a bifurcated crank-arm embracing the plunger and engaging means independent of said roller carried by the latter to actuate the same.

2. In a press, the combination of a-body portion, a plunger-head movable therein, a plunger pivotally connected with said head and bifurcated at its free end, a roller mounted in said bifurcation, rollers upon opposite sides of the same; a quadrant with a cam-slot and IOO a crank-arm having bifurcated ends to enito brace the plunger and quadrant and to enbrace the plunger and quadrant and to engage said. outer rollers. gage said outer rollers, and means for return- 3. In apress, the combination of abody poring; the plunger and head to their normal potion, a plunger-head movable therein, a plunsition.

a crank-arm having,` bifureated ends to emger pivotally connected with said head and TILDEN SHANK. bifurcated at its free end, a roller mounted in "Witnesses:

said bifurcation, rollers upon opposite sides S. M. MALEY,

of the same, a quadrant with a cam-slot and C. R. GLASS.
