BENJAMIN OBORN, OF MARION, OHIO.

HAY-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 330,918, dated November 24, 1885.

Application filed October 2, 1885.

To all whom it may concern:

Be it known that I, BENJAMIN OBORN, of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Hay-Elevators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hay elevators and carriers.

' In that class of hay-elevators which are adapted to be reversed by changing the location of the fixed pulley it has been customary to either construct the carriage in two parts, the lower section being arranged to swing around on a swivel-connection or its equi valent, or it has been necessary to change the attachment of the rope to the elevator or some portions of the guide or latch.

The object of my present invention is to provide an elevator and carrier which may be reversed by changing the fixed pulley without making any changes whatever in the carriage and its attachments.

A further object is to provide a latch which may be worked in either direction with equal facility, and to provide a simple, effective, and inexpensive elevator.

With these ends in View my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure .1 is a view of the elevator in side elevation, and Fig. 2 is a similar view of the opposite side.

A represents the carriage of the elevator suspended from the track B, and adapted to travel thereon by means of two or fourpreferably four-wheels, O. The carriage is formed of a single piece, and is consequently less expensive than when formed of two or more parts, and stronger than two-part carriages of the same weight. One side of the carriage is provided with a pair of pulleys, D D, located in the same vertical plane, and approaching each other as near as is consistent with a free rendering of the hoisting-rope E between their faces. On the other side the carriage is provided with the latch mechanism. This consists of a pair of curved levers, F F, shaped something like a pair of pinchers.

Serial No.178,824. (No model.)

Their short arms f f are adapted to embrace the opposite sides of the stop-lug G, secured to the under side of the track, and their long arms curved semicircular shape toward each other, the ends being adapted to engage a laterally-extending arm or lug, h, secured to or formed integral with the side of the gravitylatch H. The latch H is pivoted to the carriage at one end, as shown, the opposite end terminating in a longer operating finger or projection, I, and a shorter retaininghook, 13. A funnel-shaped entrance, K, formed in the bottom of the carriage, is adapted to guide the loop k of the movable-block strap L into engagement with the finger I.

M represents the movable block or pulley. A cross-bar or pair of cross-bars, m, is or are provided with perforations in their ends, through which the hoisting-rope E extends, and by which it isheld in position on the face of the pulley M. The hoisting-rope E is secured at one end to the end of the carriage opposite the pulleys D D. From thence it leads through one end of the guide m, be neath the pulley M, upwardly through the opposite end of the guide m, and from thence between the pulleys D D and off to the fixed pulley (not shown) in either direction, as may be desired.

Fig. 1 represents the several parts in the positions which they assume when the carrier is locked in position over the hay to be ele vated and the movable pulley with its load is being elevated.

As the loop is engages the finger I, it lifts the gravity-latch H, inserting the hook t through the loop is, and raising the arm or lug it out of engagement with the ends of the levers F F. At the same time the strain on the rope E either toward the right or left will swing that lever F F on the opposite side of the stop G from the feed-pulley out of engagement with the said lug G, or will tilt it sufficiently to allow it to slip past the stop, and will at the same time insert the lower end of said lever F or F under the arm h, and thereby lock the hook i in elevated adjust-- ment within the loop k. The carriage is now free to move along the track, with its load, to the point where it is to be deposited. As the carriage returns to raise another load, the lever F or F engages the stop G, and its lower end is thereby tilted'outwardly as its upper end slides beneath the stop, the arm h is released, the latch H drops, and the movable block is free to run downwardly. v

The construction of the lock-levers F F and the latch is such that, no matter in which direction the hoisting-rope leads toward the fixed pulley, they will act in precisely the same manner, while the two pulleys D D admit of the change of the fixed pulley from right to left without the slightest rearrangement of the working parts connected with the carriage or movable block.

It is evident that theform and arrangement of the several parts might be slightly changed in many particulars without departing from the spirit and scope of my invention; hence I do not wish to limit mys lf strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hay-elevator, the combination, with "the carriage, of a pairof sheaves or pulleys journaled therein and adapted to receive the hoisting-rope leading in either of two opposite directions, and thereby operate the elevator in either of said directions without changing any part of the carriage or its attachments, 30 substantially as set forth.

2. In a hay-elevator in which a pair of ing witnesses.

sheaves or pulleys journaled in the carriage are adapted to receive the operating-rope from opposite directions, and thereby move the carriage in the direction from which it leads, the combination, with the gravity-latch and the funnel-shaped guide adapted to conduct the loop on the movable block into engagement with the gravity-latch, of a pair of bent locking-levers adapted to engage the stop on the track and an arm on. the gravity-latch, for the purpose substantially as set forth.

3. In a hay-elevator, a carriage-frame cast in one piece, substantially as set forth.

4:. In a hay-elevator, the combination, with the carriage provided with the pair of sheaves or pulleys for changing the direction of the carriage, and a movable block provided with a looped strap and a cross-bar guide, of the gravity-hook adapted to engage the loop, sub- 50 stantially as stated, and the pair of ,lockinglevers adapted to engage the opposite sides of the stop and the arm on the gravity-latch, substantially as set forth. i

In testimony whereof I have signed this 55 specification in the presence of two subscrib- BENJAMIN OBORN.
