HORSE HAY-FORK.

SPECIFICATION forming part of Letters Patent No. 233,533, dated October 19, 1880. Application filed September 6,1880. (No model.)

To all whom it may concern:

Beit known that ILJOHN A. MGANULTY, a citizen ot the United States, residing at Indiana,in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Hay-Forks 5 and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it apro pertains to make and use the same, reference being had to the accompanying drawings, and to letters or figuresof reference marked thereon, which form a part of this specication.

Figure 1 is a side elevation, showing the fork as in readiness to be plunged into the hay. Fig. 2 is a side elevation, showing the fork as in position when raised from the hay-load and carrying on its extended fin gers a mass of hay. Fig-3 is a detail in section on line ac w of Fig.

2o 2. Fig. 4 is a detail on line y y, Fig. 2.

The design of the present invention is to produce an easily-operated, strong, and service` able fork for use in hay elevators and stackers 5 and the novelty consistsvin the construction of the device and the combination of the several parts of which it is composed, all as will now be more fully set out and explained.

In the accompanying drawings, A denotes the bail or loop of the fork, by which it is at- 3o tached to or connected with the carriage of any hay elevator or stacker. This loop is preferably elliptical in form, and near the lower part its sides or legs a are not brought together, but are prolonged for a considerable and proper distance. To and in their lower ends are pivoted, at b, the lingers B. At the lower part of the loop A its sides or legs a are secured in place by the yoke or band O, which can be made of two pieces clamped to- 4o gether by bolts and nuts c, or these sides can be secured in any desired way or manner.

The central stem or rod, D, can be moved up and down between the sides a, and to its lower end are pivoted, at b', the inner ends of .1,5 the fingers B. At its upper end this stem or rod D passes through a slot or hole in the yoke or band C about midway between the two sides a, and is secured to the elliptical ring E,

which is sustained about centrally in the loop A on the pulley or roller L, and has movement 5o between the upper ends of the tlat cheek or side pieces, F. These side pieces are fastened at their lower ends to and outside the yoke or band G by the the same bolts c which unite the parts of the yoke together. This ring E can be raised or lowered by means of the looplever H, bent at h, and there pivoted, at f, between the upper ends ot' the cheek-pieces F outside ot' the ring E. The long end ot' this lever H extends outside of the loop A, and can 6o be raised or lowered by means ot' the rope I, attached to the arm K, hinged in the outer part of H. This rope runs thence up and outward, and is operated by the attendant according as the lingers B are to be opened or closed.

In the inner and opposite end of this looplever is pivoted the roller L, which thus comes inside of the ring E, and when the arm K is down it draws down the long outer end of the 7o lever H. This raises the opposite short end H', and thus the roller L, acting inside the flattened ring E opposite to its joint of suspension, raises it up in its grooved path on the side a of the loop A. When these parts are in this position the fingers B are closed and point downward, as shown in Fig. 1, and in this condition the fork is in readiness to be let down into the hay on the carriage. When thus let down the fingers can be opened, as 8o seen in Fig. 2, by raising the lever H, when they will be so extended under the mass of the hay that when the fork is drawn up by the usual means or mechanism in hay-elevators the extended ngers will bear away a full 8 5 load ot hay. When the ngers are so extended the loop-lever H will be moved up on the side of A until the offset 7c on the under side of the jointed arm K falls into the notch a on the outside of a. Thus the fingers B 9o will be retained in this outspread position until the hay or straw has been carried by the movement ot' the fork on the elevator to the proper place of discharge on the mow or loft, when the arm K can be raised by drawing on rope L, and thus released from the notch a',-

then the weight of the hay will cause the fingers B to corne together and let the hay slide oi'; then the fork will be ready for again being placed into the hay for another load.

Having thus described my invention, what 1 consider new, and desire to secure by Letters Patent, is-

1. In a hay fork, in combination with the loop A, having legs a, secured together by straps or yoke C, and the fingers B, pivoted thereto, and the central stem, D, pivoted to ngers B, the ring E, hung between the side pieces, F, and lever H, whereby said stein is
