IMPROVEMENT lN HAY-ELEVATORS.

Specification forming part of Letters Patent No. 39,128. dated July 7, 1863.

To all whom it may concern Be it known that I, JAMES M. DICK, of Buffalo, in Erie county, and State of New York,

I have invented certain new and useful Improvements in a Device or Means for Unloading Hay; and I do hereby declare the following to be a clear and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. v

The nature of my invention consists in the employment of a bar of iron, steel, or other suitable material, sharp at the point, and bent into the form of a corkscrew, which is connected at the top with a handle and swivel, and so constructed that the handle may be allowed to act as a swivel or be made fast and stationary by means of a bolt.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 2 represents a side elevation of the instrument complete. Fig. 1 is a side elevation showing the manner in which the hay or grass is held up by the screw.

A is the handle, by which the instrument is screwed down into the hay. This handle is made to revolve easily around the shaft J. It is kept from moving down up or down by two flanges, (marked G and H.) The upper flange, G, has a slot into which the end of the bolt D is placed when it is necessary to prevent the handle A from revolving.

G is a swivel-joint.

I is a ring by which the instrument is suspended.

The dotted lines F represent that partof the shaft J which passes through the handle.

When in use the instrument is operated as follows: It is attached to a tackle at the ring I. The bolt D is'then forced down into the groove in flange G, as shown in Fig. 2. The handle is now stationary and fast on the shaft J, and the instrument may be screwed down into the hay, as shown in Fig. 1. It is then raised by means of the tackle. then raised up as in Fig. 2, which leaves the screw B free to revolve as the weight of the hay will cause it to while coming or dropping off from the screw. The bolt D is raised by means of the rope O. I also use a hook to prevent the hay from turning and coming off the screw while being hoisted up. This hook is marked L. It is fastened to a staple at the point marked L. When not in use it is fastened in another staple at M.

What I claim as myinvention, and desire to secure by Letters Patent, is

1. The employment of the screw B, in the manner and for the purpose herein described and set forth.

2. The bolt D,in combination with the flange E and screw B, when used for the purpose herein specified. I

3. The hook L,in combination with the handle A and screw B, when used as herein set forth.
