MACHINE FOR HOIS'IING HAY, 8w.

Specification forming; part of Letters Patent No. 27,994, dated Apri1'24, 1860; Reissued September To all whom it may concern:

Be it known that I, JOHN S. LLOYD, of

Salem, in the county of Salem and State of New Jersey, have invented a new and useful improvement in machinery for elevating or hoisting hay, grain, coal, sand, marl, or other material and depositing the same in any place desired; and I do hereby declare thatthe following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

Figure 1 is a perspective view of the machinery as seen in operation, in which A represents an inclined single rail railway, attached to the rafters of a barn or other building near the peak, or to a frame overhead, by framework shown at B in Fig. 3.

On the upper side of this rail is a groove or gutter in which the wheels B, B, attached to the blocks D, D, move to convey the hay, grain or other material to or over any part of the barn or other place required. Upon the axles of these wheels, are placed the arms C, O, which connect together at the bottom and form part of, or are firmly secured to the side of the upper double block D. Upon the upper part or top of this block are firmly fastened the two arms E, E, which terminate in loops to which are attached the ropes G, G, the forward one of which passes around the pulleys in the blocks D, D, under the railway A, to the opposite end of the building or frame, over the upper pulley I and under the lower pulley I, to the swingle tree L, to which the horse is harnessed. The rope attached to the other arm E, )asses over the pulley I, at the lower end of the railway, and is fastened to the weight W, to pull back the wheels B, B, after the fork or bucket has discharged its load. To the lower block D is attached the fork F, by means of a joint or hinge, which allows it to move forward freely. The fork is kept to its place and prevented from discharging prematurely by a bolt or slide K placed upon the handle or shank of the fork, and confined to REISSUEH its place by loops or clasps, which allow it to have a slight motion along the shank. The head of this slide is beveled upon one side, and on the other is fitted into a notch n, in the lower end of the lower block D. A spring .9 placed either in the handle or head of the fork keeps the slide in its place.

To the lower end of the slide a rope or cord is attached, by means of which the slide can be drawn from the notch n, and the load discharged at any given point.

The lower or outer end of the railway A, is supported by a stout'iron strap H, one

railway, and the other end is firmly bolted to the rafters at the apex. here the machinery is used in a frame instead of a building, the lower end of the railway should be supported by a post firmly placed on the ground instead of this strap. At the opposite end of the building or frame are two pulleys I, I, placed nearly under the railway. The rope Gr passes over the upper pulley, which is near the railway perpendicularly down, under the lower pulley, which is placed near the ground to the swingle tree L to which the horse is attached. Immediately in front of this, and at half the distance from it required to be traversed by the horse in raising the weight, a stout box is sunk in the ground into which the bottom of the post P is fitted. By this ar rangement the post can be readily taken away when not in use. The back part of this post is beveled toward the top, so that the rope in passing around it is thrown into the groove of the pulley I placed on the upper end of the lever'R, which works in a hollow in the upper end of the post P to which it is attached by a pin or 'bolt upon which it turns forward. The outer part of the lower end of this lever is beveled, and the inner part is notched at n, so as: to fit against the front of the upper part of the slide K, which is attached to the front of the post P, by clasps which allow it to work perpendicularly. The head of this slide is end of which is fastened to the end of the.

beveled on the inside. When the slide is'in' its proper position, the head or upper end of it fits into the notch n, in the lever B, and prevents the bottom of it from moving inward. It is kept to its place by a spring S which passes through the post at 39 into a notch or hole in the slide. This spring is kept to its place by a wedge half its length inserted in the post P, beneath it, and made to fit tightly. A rope f is attached to the lower end of the slide, and passes under the pulley I, placed in front of the post near the bottom, by means of which the slide K is drawn down, and the head of the lever B allowed to move forward and liberate the rope G without having to back the horse.

A broad band Z2 passes around the back and sides of the upper part of the post P, which serves the double purpose of strengthening the post and furnishing a firm support for the pin or bolt upon which the lever B turns.

Fig. 2 represents a back and lateral view of the fork F, blocks D D, slide K, joint J, notch n, and cord 9.

In Fig. 3, A, represents the end of the barn, and B the method, by which the railway with the rafters of the building or with a frame, so as to allow the wheels B, B, Fig. 1 to work upon the railway free from all obstruction.

Fig. 4 represents a self adjusting bucket A upon the sides of which are placed obliquely two pieces of wood or metal as shown by B, the upper part of which terminates in cars or bales for receiving the handle or bale of the bucket, and the lower part supporting the hinge g at the lower corner. These pieces are placed opposite and so firmly attached to the bucket as to sustain its weight when filled. The bottom of the bucket is movable and is designed to turn upon the hinge g to which it is attached at one end. The other end rests upon the notch 17,, in the spring f. Upon the under side of this bottom, and connected with it by the clasps or loops 6, e, is a slide C, which passes a short distance beyond the bucket, at the back part, and terminates at the other end, in a large oblong head d, which is beveled on the upper side. When in its natural position the under part of this head projects below the bottom of the spring and on a line with the inner surface of the bucket. The spring f is firmly fastened upon the front of the bucket, in such a manner that when in a state of rest, the notch n, passes under the front part of the movable bottom and supports it in its place. When ready to be discharged the projecting part of the slide C, strikes against a post or other firm substance and is driven forward against the lower part of the spring f driving it off and forcing the notch 92, from under the bottom, when the pressure of the materials within the bucket presses open the bottom and effects a discharge. When the bucket again descends to the ground the projecting head of the slide first strikes and forces the bucket into its proper position on the notch 'It.

D, D, represents the strap by which the block is fastened, and also the hook which connects to the handle or bale of the bucket.

Fig. 5 represents an ordinary scoop which is merely designed to be set upon the fingers of the fork F, Fig. 1, and secured to its place by screws passing through its head into the shank of the fork.

Operation: In unloadin hay, the fork F is dropped upon the load standin under the lower end of the railway, and fil ed with hay by pressing the fingers of the fork into the load or otherwise. The horse attached to the rope G at L is then started forward, drawing up the fork F until the blocks D, D, come together, when the wheels B, B, are drawn forward up the inclined railway, carrying along the fork and hay. When at the desired oint, the rope g, attached to the slide K 1n the fork F, is pulled, when the fingers of the fork turn, and the hay slips off, by its own weight. In drawing up the fork or bucket the horse passes around the post P and returns to the place of starting. Then the contents of the fork or bucket are discharged, the cord attached to the slide in the post P is pu led, and the rope G, which had passed around the post, and guided by the beveled back into the groove of the pulley I at the top of the post, draws the upper end of the lever B forward allowing the rope to pass out of the groove in the pulley and become slack, when the weight W draws the wheels B B, down the inclined railway to the lower end of it when the fork F again drops upon the load by its own weight. The lower end of the lever B being heavier than the upper, it returns to its proper position when released from the rope, by passing over the beveled head of the spring 8 and forcing it downward either by its own force, or that of a person, until the spring again moves up into the notch n. By holding the spring down by the cord f until the lever had fallen back to its place, the result would be most readily accomplished.

The mode of operatin the machinery being so nearly the same or all kinds of material a further description of the mode of operating is deemed unnecessary.

I do not claim the invention of blocks, pulleys, forks or railways for raising hay or other material, but

What I do claim and desire to secure by Letters Patent is 1. The construction, combination and arrangement of the fork, bucket, cords, levers,

pulleys, sprin%s and railway, the arms E E 2. I also claim the post P, as constructed to the block and the mode of attaching in combination with the pulley, lever, slide, and supporting the railway t0 the barn or spring and cord.

frame so as to allow the wheels B B, with JOHN S. LLOYD. 5 the attached blocks and fork or bucket, to Witnesses:
