IMPROVEMENT 1NV HORSE HAY-FORKS.

@the rlgehnh referrer tu ir time Enters zztnnimrennhmmumnlhtnmt I TO ALL WHOIWI IT MAY CONCERN Be it known that We, SAMUEL HARRIS and DANIEL A. HARRIS, of Shippensburg, in the county ot Cumberland, and State of Pennsylvania, have invented a new and improved Hay-Fork; 'andn'e do hereby declare that the following is a full, clear, and exact description thereof',4 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, in I Which Figure l representsa side elevation of our improved fork, in a position while raising the hay. 'Figure 2 is a side elevation of the fork in a position afterdumping.

Figure 3 is an edge view of the same. l Figure 4 is a front View of a double fork constructed on our improved plan. Similar letters ofreference indicate like parts. Our invention relates to a hay-fork of that cla-ss known under the name of harpoon fork. v The invention consists in the construction of thelevers and bars by which the finger or harpoon is operated;

the whole construction being so simple and substantial that the fork is not liable to get out of order easily. v

The same principle mayy beemployed on a douhlefo'rk, that is, a. fork with two harpoons or fingers, which point towards each other when brought to a horizontal position. Y

A represents the main bar of the fork, to its upper cud being attached the rope B, by which the fork is lowered or raised. Tothe lower end of bnr A is pivoted the harpoon or finger C, by means of a. pin, a. The rear end of the finger C projects beyond the pivoting-pin fl, and is secured by a pin, b, to the rod D. The rod D extends up, and is secured to the lever E by a pin, c. A curved bar, F, which extends from, and is rigidly secured to, the bar A forms the support for the lever E, and is pivoted to it by the -pin cl. When in the position shown in iig. 1, no Weight on the finger C will be able to depress the said finger, and bring it to the position shown in iig. 2, as the pin c isthroivn even beyond the line that may be drawn from b and cl, and so the. weight on the Enger C would have the tendency to press the point c ot' the lever E against the bar A.4 Only by pulling on the rope f will the linger be depressed and brought to the position shown in fig. 2. Thus it is seen that Without the use of springs, slots, hooks, or other devices, which tend to wenken an instrument like this, our fork` willbe very firmly locked, while elevating the hay.

'The same principle rnay be employed on double forks, like the one represented in tig. 4. In this the fra-mc A takes the place of the bar A, the lingers C are connected to the levers E', by means of the rods D. The operation is similar to that of the single fork. To bring the ngers to a vertical or discharge position` the levers E will have to be raised towards thc support-bar A, on which the fork is suspended by a rope.

Having thus described our invention, we claim as new, and desire to secure by Letters Patent- Pivoting the lever E to the forked .arm F of the bnr A and to the lever D, as herein described, in such a manner that the Weight upon the finger C will cause the upper end of the lever E to be drawn toward said bar A, thereby securing and retaining the finger C in a horizontal position, as herein shown and described.

DANL A. HARRIS. Witnesses:
