UNITED STATES PATENT FincEo FRANK H. BOL'IE, OF MILVAUKEE, VVISGONSIN, ASSIGNOR TO THE EGEL- IIOFF MANUFACTURING COMPANY, OF SAME PLACE. f

HORSE HAY-FORK.

SPECIFICATION forming part of Letters Patent No, 307,906, dated November 11, 1884.-.

Application led May 1G, 1884. (No model.)

To all whom it may concern.-

Beit known that I, FRANK H. BoL'rn, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented cer- 5 tain new and useful Improvements in Hay- Forks; and I do hereby declare that the following is a full, clear, and exact description thereof.

illy invention relates to improvements in 1o hay-forks, and will be fully described hereinafter.

In the drawings, Figure l is a perspective View of my improved device. Fig. 2is avertical section of the broken upper part of the same, showing the fork when locked t'or hoisting; and Fig. 3 is a like section of the sanne, showing the fork locked for loading.

The object of my invention is to simplify the locking mechanism of that class of hayforks known as harpoon-forks, and thereby considerably reduce the cost of manufacture and render the operation of the fork more efiective and its working parts less liable to get out of order.

A is the sheath ot the fork, and B the sliding rod, to the lower end of which are attached the retaining-times b b. The upper ends of the side bars lof the sheath are provided with ears c c a2 a2, projecting outward and perforated 3o to receive the connecting-pins a c, both ends of which are riveted against the outer faces of said cars, while the inner faces of the ears rest against shoulders upon said pins. Hinged n on the pin a, between the ears a2 at of the side bars of the sheath, is the lockinglever C. The hinged end of this lever has dat-faced shoulders c c', formed on the opposite sides, which shoulders are designed to lock the fork in the positions required either for piercing 4o the hay or for locking the tines when loaded by bringing one or the other in close contact with the adjoining face of the sliding rod B. For that purpose the opposite face of this rod 'is formed in the notched face of the sliding has the semicircular notches b b2, in one of which lits half of the pin at as the sliding rod Bis acted.` upon by one or the other ofthe shoulders cc ofthe locking-lever C. In the position represented in Fig. 3 the shoulder c is in contact with the rod, holding the notch bi in engagement with the pin a4, thus locking it in place prior to its introduction into the hay. In the position shown in Fig. 2 the shoulder c is in Contact with the rod, with the notch b engaging the pin at. A stop, o",

rod B, just below the notch b2. to prevent said rod from sliding too far out of the sheath.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a hay-fork, the combination of the sliding rod B, provided with two notches in its rear edge, the inclosing-sheath A, having its sides connected at the top by two pins, one in front and the other in rear of said rod, and a locking-lever pivoted to the front pin, and having a dat-faced projecting shoulder on each side of its pivoted end, whereby one or the other notch in said rod may be locked in e11- gagement with the rear pin, substantially as set forth.

2. .In a hay-fork, in combination with the sheath A, having ears a a c2 a2, and connect-- ing-pins a a, thesliding tineoperating rod B, having notches b b2 and stop b3, and the hinged locking-lever C, having shoulders c c', substantially as and for the purpose set forth.

In testimony that I claim the foregoing l have hereunto set my hand,v at Milwaukee, in the county of Milwaukee and State of VWis- 8o consin, in the presence of two witnesses.

FRANK H. BOLTE.
