EDMUND HARRISON, OF 'MOUNTAIN VIEW, CALIFORNIA.

IMPROVEMENT I-N A PPARATUS FOR UNLOADING HAV, &c.'

Specification forming part of Letters Patent No. 118,531, dated August 29, 1871.

To all whom it may concern:

Be it known that I, EDMUND HARErsoN, of Mountain View, in the county of Santa Clara and State of California, have invented a new and use- Hay, Grain, Ste.; and I do hereby declare thatv the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a side view of my improved apparatus. Fig. 2 is a detail bottom view of the receiver. Fig. 3 is a detail side view of the bottom barsof the same.

Similar letters of reference indicate corresponding parts.

My invention has for its obj ect to furnish an improved apparatus for unloading hay, grain, te.,

a wagon-box or rack, for stacking hay or grain, and removing grain from a stack or mow to feed and inexpensive in construction, speedy and effective in operation, and conveniently operated; and it consists in the construction and combination of various parts of the apparatus, as hereinafter more fully described.

A is the receiver, which is designed to cover or be spread over the inside of the bed or rack of the wagon, and to be under and around the load. The receiver A may be made of heavy canvas or of a network of small ropes. The receiver A is made in two parts, and its edges may be strengthened with ropes. The outer edges of the two parts are attached to side and end bars al, to keep said edges extended. The adjacent edges of the bottom of the receiver A are attached to two bars, a2, each of which may be made in two or more parts, jointed to each other at their ends. The bars c2 I prefer to make in the form of angle-irons, the vertical iian ges of which lie along each other, and to the lateral iianges of which the netting or canvas is attached. To the vertical iiange of one of the bars c2 are attached keepers or staples, which pass through holes or slots in the vertical iiange of the other bar, and which receive hooks or bolts to lock the sa-id bars a2 to each other. The lock-bar a3, with which the lock-hooks or bolts are connected, ex-

tends along the angle of the bar a2, and is kept in place by and works in keepers attached to said bar a2. The lock-bar a3 is jointed wherever the bars a2 are jointed, and is operated by the lever a4, to which one of its ends is pivoted, and which is pivoted to the bar a2, to which the lock-bar a3 is pivoted. rlhe lever at is made of such a length that it may be conveniently operated to lock the parts of the receiver to each other, and to its end is attached the end of a cord, a5, which extends down into such a position that it ma-y be conveniently operated to unlock the parts ofthe receiver and discharge its contents when the receiver has been brought over the place upon which the load is to be deposited. To the side and end bars al, near their ends, are attached ropes a6, provided with eyes to hook upon hooks attached to the corners of the Wagon-box to keep the receiver extended while receiving the hay or grain. Vhen the loading has been completed these eyes are detached from the wagon-box and are hooked upon hooks attached to the corners of the frame B. Additional ropes as may be attached to the middle parts of the side and end bars a? When desired or necessary. rIhe frame B should be made somewhat smaller than the receiver A, and to its central part is attached the end of the hoisting-rope C for raising and lowering the receiver A. D is the derrick-pole or shaft, which should be thirty feet, more or less, in height, and the lower end of which is pivoted to the bedplate E, which should be staked or spiked to the ground or `floor in the place where the hay or grain is to be handled. The upper end of the shaf't D is swiveled to a plate, F, to which are attached the upper ends of a suflicient number of guy-ropes, G, to hold the said shaft securely in position. The lower ends of the guy-ropes Gr are staked to the ground or are attached to other suitable supports. H are the arms of the derrick, the inner ends of which are hinged or jointed to ears. attached to the upper parts of the shaft D, so that the outer ends of the arms H may be raised or lowered, as may be desired. I is a rope, the ends of which are attached to the outer ends ofthe arms H, and which passes through a hole or around a pulley in the upper part of the shaft D. To the middle parts of the arms H are attached the upper ends of the ropes J, the lower ends of which are secured to belaying-cleats or'` other suitable supports attached to the lower part of the shaft D, so that, by adljusting the ropes J, the arms H may be adjusted Without its being necessary to ascend the shaft D or lower it to adjust the said arms H. The hoisting-ropes C pass over a pulley, K, connected with the outer ends of the arms H, and over a pulley, L, connected with said arms H, but placed further in- Ward or toward the shaft D. rEhe ropes C then pass down and around pulleys M, pivoted to the bed-plate E as near as possible to the foot of the shaft D, and to them is attached the draft.

For stacking hay from the cock or Wagon, and

for various other purposes, it may be advisable to use a hay-fork, N. In this case a fork, N, should be attached to the end of the hoisting-rope C of each arm H, so that an empty fork may be descending While a loaded fork is ascending; andv the two hoisting-ropes G should be continuous, so that the horse, When moving in one direction, may raise one fork, N, and When movin g back, or in the other direction, may raise the other fork, and thus need not make a round trip for each fork-load.

Having thus described my invention, I claim as neyg and desire to secure by Letters Patentl. The receiver A al a2 a3 a4 a5 a6 and frame B, constructed and operating, substantially as herein shown and described, to adapt it to receive the hay or grain and transfer the load bodily, by means of a derrick, to the place Where it is to be deposited, as set forth.
