Lam Plllt'hl N .101,407, dated March 29, 1870.

IMPROVED ELEVATOR.

The Schedule referred to in thfllb Letters Patent and making part f the lame.

To all whom it may concern:

Be it known that I, Hmsu 0. 81:0 urrnn, of Salem,- in the county of Golumbiana and in the State of Ohio, have invented certain new and useful Imprln-ements in Elevators; and do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification. v

The nature of my in ention consists in the constrnction and arrangement of an elevator for hay, grain, and other similar articles, with animproved latching-device attached to the same.

In order to enable others skilled'in the art to which my invention appertainsto make and use the same, 1 will now proceed to describe its construction and upemtion,referring to the annexed drawings, in which-'- Figure 1 is a side view of the entire elevator, and

Figure 2 is an enlarged longitudinal vertical section of the latching-device.

A represents the frame-work of a barn or hay-mow of any desired dimensions and construction.

In the upper portion of this frame is stretched a wire rope, B, from which the carriage C is suspgnded and moved back and forth. This wire rope is used for heavy loads; for light loads it may be entirely 'dis 1, said bail also swinging from the axis of the pulley D, and having a loop, b, immediately in-i'ront of the pulley E.

The carriage C is provided with a pulley, H, at its.-

upper end, and a similar pulley, H, at its lower end; and at the upper end of the carriage are two arms, :1

d, between which a pulley, I, is pivoted, the wire rope B passing between said arms under the pulley I, the pulley resting and moving on'the wire rope, by which means the carriage is suspended from the same.

The'side or rather edge of the carriage nearest the bail G is slotted for 2. sm table distance for the insertion of the bail, and under said slot within the carriage is pivoted a latch, J, constructed in the peculiar shape shown in fig. 2, having teeth or projections e e on its upper front, and rear corners, and a tooth, or projec-' tion, i, on its under side. Under the latch J is pivoted a lever or pawl, K, the front end of which catcheszon the tooth i to lock the latch, while the other-or rear endis weighted so as to hold the pawl in proper position. From this rear end a rod, f, passes downward, and

is, at its lower end, below the carriage, provided with a loop, 11.

The hoisting-rope L is attached at a suitable point on the under side of the carriage O, and passes under a pulley, m, in the top of the hay-fork, and up through the loop haround or over the pulley H, then around the pulley D and under the pulley H, over the pulley I), and down to the horse-power.

()n the front edge of the'carriage just above the slot therein is attached another rope, M, which passes through the loop b on the bail G, over the pulley B, and downward, being, at its lower end, provided with a weight, N.

The operation of this elevator is'very simple. The fork being loaded and the horse-power put inv motion, the fork with the load is raised perpendicularly.until 'the pulley m. on the fork strikes the loop h at the lower end of the rod f, which raises the weighted end of the lever K, removing its front end from the projection i on the latch. The front or outer end of the latch J being the heaviest, it falls down assoo'n as the lever or pawl K is removed from the tooth i, releasing the bail G, causing the carriage to move on the wire rope B to any point desired to unload the hay. \Vhen unloaded and the hoisting-rope is slackcd up, the weight N draws the carriage toward the bail G. The man ner of attaching the rope M to the carriage and passing it through the' loop b causes it to guide the bail G so that it will enter the slot in the carriage, striking the rear projection, d, on the latch J causiug its front end to rise so that the pawl K will catch on the tooth i, holding the upper front projection, e, within the bail, and thus locking the carriage, when the fork descends by its own weight, to be againloaded and hoisted up.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The latch J, constructed as shown, and provided with teeth or projections-c c and a, substantially as and for the purposes herein set forth.

2. In combination with the latch J, constructed as shown and described, the weighted lever K, rod f, and loop It, all substantially as and for the purposes herein set forth.

3. The combination of the bail G, slotted carriage O, latch J, lever or pawl K, 'with rod f and loop h, all constructed and arranged to operate substantially in the manner and for the purposes herein set forth.

In testimony that I claim the foregoing, I have I hereunto set my hand this 15th day of ,March, 1870.

HIRAM O. STOUFFER.
