ABRAHAM w. yLezen-R, orA NEW YORK, N. Y. Leners Patent No. 88,397, dazed March 3o, 1869.

VThe-Schedule referred to in these Letters Patent, and 'making part of the lima' To `all whom t ma/y concern:V

l Be it known that'I, ABRAHAM W. LOZIER, of the city, county, and State of 4New York, have invented certain new and useful Improvements in Hay-Elevating Forks; and I do hereby declarethe following to be a,

full, clear, and `exact description of the construction and operation of the same, reference being had to the accompan yin g/drawings, 'in which- Figure l is a View df my fork when closed, to grasp the load to/be elevated.

Figure? is a view of the same when opened, to be thrust into the hay.

Y Figure 3 isa sectional detail view., Similar letters of reference indicate like parts in the several drawings.

This :invention is animprovement upon the hay-elev rating fork for which Letters Patent `were granted to me, December l, 1868, No. 84,559, and consists ina` novel arrangement and combination of the fork with-l Ithe head, so that the latter may be readily used as the handle by which to manipulate the fork, as well as to hoist the load.

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

A represents the head, in which the tines G O are Vfirmly secured. in the manner represented ing'. 3.-

, A plate, F, formed of one piece of metal, is bolted v to this head, and constitutes a hinge for the bar B,

which is pivoted to it by the bolt c.

The third tine,D, fits in a socket inl one end ofthe bar B, and-is held in place -by a setscrew,.h. On the bar B are secured the pulleys d e j; and t0 itis pivoted the tripping-lever E, held in position by the coil-spring k, vand operated bythe rope j.

The curved end c of the platelli" rests on a ledge on the end of the tripping-lever, and holds the grasping-tiues G in proper position to retain the load. v y The pulley e is securedto the'bar Bin such Vposition as to form astop when the bar is turned back, whereby itis held in a rigid position with respect to me head A, and forms a handle in operating the fork. y

The fork being attached to the hoist-rope i, it is op erated as follows:

The operator, ,having turned the bar B back until,

the stop e strikes against the head, grasps it with one hand, and seizing one of the tines, Q, with the other, thrusts the two tines into or under the hay; then, by throwing the bar B over the tine D, cuts iilto the hay,

and the ledge on the end of the tripping-lever E springs into place, beneath the catch a, so that when power is applied to the hoist-rope, the several parts ofthe fork are held in their proper positions to grasp and retainw jmeans of the pulleyf.

It will be evident tliata hay-fork as described, though very simple in construction, and composed of few parts, is yet very elieotual in operation, not liable to become disarranged, and easily manipulated.

What I claim, and desire to secure by Letters Pat- The arrangement and combination of the fork-tines O G, fork-head A, pivoted hoist-bar and handle B,

plate F, and catch E, the whole constructed and operating substantially as described.
