IMPROVEMENT IN HORSE HAY-FORKS.

Specification forming part of Letters Patent VNo. 47,982, dated May 30, 1865.

To all whom it 11mg/ concern.-

Be it known that we, RENssELAER REY- No'Lns and CHAnLEs'YoUNG, both of Stockport, in the county of Columbia` and State of New York, have invented a new and Improved Hay-Fork, and we do hereby declare that 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 drawings, forming part of this specification, iny which- Figure l represents a side elevation of our invention when closed and in the position of being hoisted up. Fig. 2 is a similar View of the same when open and ready to take in a fresh load. Fig. 3 is a frontelevation of the same.

This invention consists in combining with two hinged tined jaws two levers or togglearms in such a manner that when said togglearms are straightened out the jaws are firmly closed, and a load of hay taken up fby them can be hoisted up to any desired height, and by a slight pull on one of the toggle-arms they are thrown out of line, and the jaws open to clamp their load; and, furthermore7 by the action of the togglelever the operation of entering the fork in the hay is facilitated.

It consists, further, in placing the ring which takes the hoisting-rope out of the center of the fork and in such position in relation to the toggle-arms and to the pivot connecting the two jaws that by the strain on the hoistingrope the opening and the closing of the fork is facilitated. i

A represents a fork made of ironor any other suitable material, and composed of two jaws, B B, which are hinged together by a Each jaw is provided with two or more tines, b b, and the pivot a, which connects the two jaws, is far from being central between the' tines,-` as clearly shown in Figs. l and 2 of the drawings.

C is a ring secured to the jaw B', and intended to take the hoisting-rope. `This ring is also out of the center on the opposite side of the pivot c, and by this position of the ring and pivot in relation to each other and to the tines the discharge of the hay is considerably facilitated, andthefork drops the load just as l it was taken up, instead of rolling it up, as is the case with most forks. For this reason our fork is particularly valuable in mowing or stacking where it is desirable to deposit the load just as it was taken up. The two jaws of the fork are also connected by two ar1ns,.D D', which are connected to each other by a pivot, c, and to the jaws by pivots d cl,'as clearly shown in the drawings. beyond its.pivot d', and is provided wit-h a loop, e, to receive the line f, which serves to discharge the load. The arms D D form a toggle-joint, and if the fork is closed the pivot c, which connects said toggle-arms, is within the .pivots d d. In this position the end of the fork retains its load, and the weight of the load itself', together with the strain on the hoistingrope, prevents the fork from opening spontaneously. The load rests on' the jaw B, and consequently has a tendency to throw said jaw in the` direction of the arrow marked near it in Fig. 1, and by this strain on said jaw the fulcrum of the toggle-j oint is pressed in, :and consequently said togglejoint is `prevented from releasing the jaws. takes place by the strain of the hoisting-rope on the jaw B". This strain has a tendency to throw said jaw in the direction of the arrow marked near it in the same figure, and the toggle-joint is held tight. By pulling the line is open, as shown in Fig. 2, a slight pressure on the fork, added to the action of the lever and toggle-joint by pulling the lever, causes the fork to catch and grasp the hay firmly with f the least possibleeffort, and this operation is further facilitated by the peculiar form ofthe tines, which are curved in such a manner that they will readily enter the hay.
