HAY- ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 233,759, dated October 26, 1880.

Application filed August 30,1880. (No model.)

To all whom it may concern:

Be it known that I, LOUIS HOEPNER, of Sandwich, in the county of De Kalb, and in the State of Illinois, have invented certain new and useful Improvements in Hay-Elevators and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference in arked thereon, making a part of this specification.

This invention relates to certain improvements in hay-carriers; and it has for its object to provide a simple and effective device that may be held stationary upon a rail until the load of hay has been sufficiently elevated, and then automatically released, so that the device may be run forward upon the track to the point required to dump the hay, the device being operated at the moment of its release to grasp the sheave or pulley, by which the hay is elevated, and retain it while being carried along the track. These objects I attain by the device illustrated in the accompanying tdrawin gs, in which Figure 1 represents a side elevation, and Fig. 2 a top view, of my improved device.

The letter A indicates a frame provided with flanged wheels B, adapted to travel upon a suitable track in such manner as to permit the frame to depend therefrom. The said frame carries a grooved pulley, 0, over which the rope, chain, or cord D, by means of which the load of hay is elevated, passes.

The letter E indicates an angle-lever, fulcrumed at its angle in a slot, F, at one end of the frame. The lower long arm of the lever is bent or curved, as shown, and has attached to it one end of the cord D.

The letter G indicates the sheave to which the hay-fork or other grasping device is at tached. under which the cord D passes, and by which the pulley and sheave may be elevated. The upper or short arm of the lever E is provided The said sheave carries a pulley, H,

with an upwardly-extending hook or catch, I, 5

which is beveled at its outer edge, and on the sides is provided with a catch, L, and 'stop M, to operate in connection with a pawl, N, piv- 'oted to an extension on the frame A, the lower end of said pawl extending between the catch and stop above mentioned, and having a shoulder, 0, which is adapted to engage the catch L, for the purpose hereinafter specified.

While the hay is being elevated the anglelever is in the position indicated in dotted lines, the hooked upper end of the said lever engaging a suitable stop on the track, by

which the device is held stationary upon the rail.

\Vhen the load is fully elevated the pulley H rides up on the curved end of the anglelever, and the final draft upon the cord D draws the said curved end toward the pulley U, the pawl N drops into position with its shoulder over the catch L, holding the pulley H fast, and releasing the hooked end of the lever from its stop and permitting the carriage to travel to the desired point for dumping.

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

The traveling frame A, mounted on flanged wheels B, and provided with a flanged pulley, C, over which the lifting-rope D passes, in combination with a lifting-pulley, H, an anglelever, E, curved at its lower end and provided with a hooked upper arm having a catch, L, and stop M at its sides, and the shouldered pawl N, pivoted to the frame A, the whole arranged to operate substantially in the manner specified.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of August, 1880.
