"L SPECIFICATION.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY NEUMEYER, of Millerstown, in the county of Lehigh, and State of Pennsylvania, have invented a new and useful improvement in Horse Hay Elevators, and I 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, in which- Figure 1 is a front view of my improved hay elevator, with the hooks projected.

Figure 2 is a side view of the same.

Figure 3 is a longitudinal section of the same taken through the line a: x, iig. 2, the hooks being drawn in.

Figure 4 is a longitudinal section of the same taken through the line y y, iig. 1, the hooks being drawn in'.

r 1 Figure 5 is a detailed sectional view of the same taken through the line z e, fig. 1..

Similar letters of` reference indicate like parts. Y My invention has for its object to furnish an improved machine for raising and transporting hay from one place to another. And it consists,fnst, in a hay elevator formed by combining the tube, bar,-hooks, catch,l spring, and lock-lever with each other as hereinafter more fully described; second, in the combination 0f the crank, shaft, cog-wheel, and spring with each other, and with the bar and tube.,

A is. a tube or hollow bar, the lower end of which is made solidand pointed, as shown, so as to be easily forced into the hay. B is a bar', the lower part of which s made of such a shape and size as to lit the interior of the tube A, but the upper part is made thinner, as shown in figs. 3 and 5, and it passes up through the upper end of the tube A. a is a pin projecting inward from the side of the tube A, against which pin the shoulder b', formed upon the bar B, strikes and stops the said bar at the proper elevation. C are hooks made inthe form represented in f1gs. 1 and 3, the upper ends of which are pivoted to the lower end of the bar B, as shown in figs. 3 and The hooksipass out and in through slots formed in the sides of the lower end of the tube Ai and they are of such a form that when drawn in their ends will be flush with the sides of the tube A, as shown in fig. 3. When the hooks C are extended in the position shown in g. 1, their lower edges rest against the edges of the slots in the tube A, through which theywork, and their ends rest against the shoulder b2, formed upon the lower end of the bar B, so that no strain comes upon the pivoting pin, however much or little weight may be suspended from said hooks C. The drawings represent the elevator as being made with two hooks prod jecting from opposite sides of thel elevator, and for ordinary purposes two will be sufficient; but if desired, four may be used, projecting from the lower end of the tube at right angles to each other. This construction may be employed with advantage when the elevation is to be used'for handling fine hay. Tothe upper end of'the bar B is attached the handle D, which is' made of such a shape and size as to be easily grasped in operating thc machine. Through one of the arms of the handle D is formed a slot, in which is placed a friction pulley, E. To the upper end of the tube A are pivoted the lower ends or arms of the catch F, which enters notches formed in the edge of the bar B, and holds the elevator with the hooks C extended, as shown in fig. 1, or witlrsaid hooks drawn in, as shown in iig. 3. The catch F is held forward to its vplace by the spring G, the lower end of which is attached to the upper end of the tube A, and its upper end presses against the said catch F, as shown in figs. 2, 4, and 5. H is the lock-lever, which is pivoted to the upper end of the bar B in such a position that when the said lock-lever is placed in the position shown in iig. 2 the notch formed in the edge of the said lever may shut down over the upper end of the catch F and hold it securely in place. The lower end of the lever H is made in the form of a cam, so that when moved into the position shown in iig. 4 it may push the catch F out E of the upper notch, allowing the, tube A to slide down along the bar B, drawing the hooks C into said tube and dropping the hay from the elevator. To enable this to be done at whatever place -fthe elevator may be, there is attached to the upper end of the said lever, H, a cord, I, which passes over the ypulley E, and thence to the place l where the operator is stationed. In using the apparatus, the parts being in the position shown in figs. 3 and 4, the tube A is forced down vertically into the. hay, the spring C and catch F` are then drawn hack with one hand, and the bar B forced down with the other. This forces the hooks C out into the position shown in iig. 1, and at the same time the spring G forces the catch F into the upper notch in the bar B, where it is secured by bringing the lock-lever H into the position shown in fig. 2. J is a shaft revolving in bearings attached to the upper end of the tube A, and which is so constructed as to have a longitudinal movement. K is a cog-wheel attached to the shaft J, the teeth of which are of such aysize as to mesh int`o the teeth formed upon the edge of the bar B. r L is a coiled wire spring, one end of which rests against .the bearing of the shaft J, and the other against the cpg-wheel hldin'g it away from the bar r B when not required `for use.' M is a crank hinged to the end of the shaft J, as yshown in gs. 1 and 2, so that when vnot vr;qu"ired.fo` 1- use it maybe'foldedover into the position shown in fig. @and be. out of' the way. This deviel is designed to be' usedwhen the 4h a'y is so solid that it `is difficult to force the hooks C out through it. In this case the shaft is movedl along until the teeth of the cog-wheel mesh into the teeth of thefhar B; then, hy'turning the crankl M, the bar B is easily forced down, lforcing the hooks C out through the hay. i i What I claim as new, and desire to secure by' Letters Patent, lis 1: The forked locking-lever H, with its -short arm or prong adapted to pressthe ,catch F in against the iiotch, and its longer arm releasing it, in combination with the rack-bar B,.a`nd slotted handle D, receiving the pulley E, substantially as described for the purpose specified. v *I 'i 2. The combination-of tho crank M, shaft J, cog-wheel K, and spring L, with 'each other and with the tube A. and bar B, substantially as described and for the-purpose set forth. i x -i f 'HENRY NEUMEYER.
