dated Janna/ry 26, 1869.

HAY-ELEVATOR AND CONVEYER.

'l'he l Schedule referred to in these Letters Patent and making part of the sama.

To all whom it may concern Be it known that I, THOMAS I. POWELL, of Naples, in the county of Ontario, and State of New York, have invented a certain new and useful Improvement in Hay-Elevators and Oonveyers; and I do hereby dethereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an elevation of the device in the locked position.

Figure 2, a similar view of the same in the unlocked position.

Like letters of reference indicate corresponding parts in both figures.

My invention consists in combining, wit-h the carriage and with a stop ou the track, an arrangement of parts by which the carriage may be locked in place on the hay, but be unlocked automatically when the hay is fully elevated and ready to be conveyed, as hereinafter set forth.

In the drawings- V A indicates the track er way, which is preferably stretched from over the load to the place of deposit.

B indicates the stop, made fast thereto; and

C represents the carriage, which is composed of a, frame, a, and trucks b b, which run upon the track.

To the under side of the carriage is pivoted, at one end, a pulley, c, and to the other a segment, D, the latter having a concentric face, j; and a stiff arm o1' horn, g.

A cord, E, is attached to the segment, passing under a pulley, h, which holds the fork-block Gr, and thence extending over the pulley c of the carriage, `and over another pulley at the place of deposit, and thence extends tothe operators hand.

A latch, H, is pivoted to the front end of the carriage, having, at the opposite end, two catches, t le, the iirst engaging with the stop B, when elevated iu the rear of the same, as in iig. l, and the latter engaging with the point Z of the segment, when depressed, as in g. 2.

An elbow, 1, is also pivoted -at m to the carriage, the arm u resting under latch H, and the forked arm o stiiding the track, so as to strike the stop B in back action, and thereby raise the latch.

The action is as follows:

When the carriage is drawn back bythe guide-cord K, the forked arm 0, striking the stop B, will throw the latch up from the position in iig. 2 to that in iig. l, thereby allowing the tackleeblock to fall to the load, and engaging the catch lwith the rear of the stop, and holding the carriage from sliding forward while the fork-load is being elevated. When the 4load has been sufficiently elevated, as in tig. 2,- the segment-block I) moves from under catch, k, allowing the latch to fall, and the carriage, with the load attached, can. then be moved forward by the continued action ofthe elevatingcord. i

I am aware that elevators and conveyers for hay have before been employed; therefore I do not claim the broad principle.

- The novelty in my invention consists in the employ ment of the autoinatic locking and unlocking-arrangement, by which the carriage is securely held while raising the load, and released for conveying it, as above set forth.

I claim the combination of the elbow I and the latch H, provided with the catches i k, when the said parts are employed in combination with the stop B, in the manner and for the purpose specified.

I also claim, in combination with the latch, the segment D, operating iu-the manner and l'orthe purpose spccied.

In witness whereof, I have hereunto signed my name, in the presence of two subscribing witnesses. NVitnesses: THOMAS I. POV/'ELL ALFRED GlnswoLn, CHARLES R. DUNTON.
