vIMPROVEMENT IN HAYSPREADERS.\

The Schedule :referred to :in these Letters Patent making part of the same.A

To all whom it may concern Be it known that I, GILBERT I. WoosTna, of Plymouth, in the county ofrLtchield and State of Connecticut, have invented a new Improvement in Il :1y-Spreader; and I do hereby declare the following, when taken iu connection with the accompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which said drawings constitute part of this specih'cation, aud-represent in- Figure 1, a top view,

Figure 2, a side view, andin Figure 3, a longitudinal central section.

This ,invention relates to an improvement in machines for spreading new-niown hay, and consists in the arrangement of the crank-shaft, so that bythe same operation -it is thrown out of "gear and the forks raised. v

A A are two ends of the frame, attached together by two cross-bars, B C, and supported. upon an axle, I), on which are arranged wheels E E, upon which the l nrichine is moved.

FF are two crank-shafts, driven, by connection with the wheels E, through gears f f.

u are the forks, each attached to its respective crank el, so t-hat the crank will turn freely therein, the upper end of the fork passing up through a fixed bar, I, ,but playing freely in the said bar; therefore, as the cranks revolve, the forks will be thrown 'from the position denoted at a, tig. 2, forward to the position at a in the same figure. The upper end being held by the bar I, the whole movement of the crank is imparted to the fork or lower end only.

The crank-shaft F is arrangedii-u Vblocks L L L,'

each hinged to its respective part' of the frame, asin figs 2'and 3, and from the central block a lever, I,

extends forward beneath the seatof the driver, upon the end n of which he can `conveniently place vhis foot.v

lever, heilig depressed, as deuotedin broken lines, ti". 3, will raise the blocksL and turn'thecrank-shaft and forks np, throwing the shaft out of gear, and thus arrest` vthe operation of the fork :it anytime whilein operation. l l

Als it is necessary, iu order to the opera-tion of the forks, that the crank-shaft shouldalways be the saine distance from the gronmhsome adjustment must he luadefor the dil'ferent'height-s of` horses. To do this, I .hinge the shafts R R to the bar ILL-as at s, and secure the shafts adjustably t-o the bar C by screws t, or otherwise, so that the shafts may begraised or lowered tolacconimodate the height of the; horse.

I do -not broadly claim oombiningthe spreading hay'.
