NlTED STATES ROBERT H. MORRIS, OF JANESVILLE, \VISCONSIN, ASSIGNOR OF ONE-HALF TO NELS GARLSON, OF SAME PLACE.

HAY ELEVATOR AND CARRIER.

SPECIFICATIQN forming part of Letters Patent No. 312,151, dated February 10, 1885.

Application filed December 20, 1884. (No model.)

T aZZ whom, it may concern.-

Be it known that I, ROBERT H. MORRIS, of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and.

useful Improvements in Hay Elevators and Carriers; 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 appertaius to make and use the same.

. My invention relates to an improvement in hay elevators and carriers, the object of the same being to provide improved means for automatically locking the hoistipg-tackle in 1 5 elevated adjustment and simultaneouslytherewith releasing the carriage, and for simultaneously releasing the hoisting-tackle and stopping the carriage.

With these ends in view my invention consists in an eccentric bar or plate pivoted to the carriage and adapted to engage a grip-lever, said eccentric being positively operated by a link pivoted thereto and adapted to engage a stationary incline.

My invention further 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 0 aview in side elevation, partly in section, of

I a hay elevator and carrier embodying my invention; and Fig. 2 is a sectional view of the carriage-way, incline, link, and eccentric through the line :0 y of Fig. 1.

A represents a track or way, on which a carriage, B, depending therefrom, is adapted to move. The carriage B is supported on the way by suitable wheels, 0. The tackle a is provided with a sheave, 1), adapted to receive a hoisting-rope, 0, on its face, with a depending hook, D, for attaching the hay-grapple, and with an upwardly-extending loop, d, for engaging and receiving the grip-lever, as will appear hereinafter. Ahoisting and operating rope, 0, passes over the face of a pulley, E, journaled near one end of the carriage, thence about the sheave b in the tackle a, thence over a pulley, F, journaled near the opposite end of the carriage. The rope is provided with knots or other suitable stops,

(not shown,) so that either end may be prevented from freely sliding over the pulleys E and F, as desired. Near the central lower portion of the carriage a grip-lever, f, is piv otally secured. The leverf has its lower end curved toward a stationary projection, f, se cured to the lower portion of the carriage, and is adapted to close in contact with the projection within the loop (Z of the tackle a. The lever f is also provided with an arm, h, which extends laterally over the loop d. The upper end of the lever f is shaped to engage the notches on an irregular-shaped eccentric,

I, and thereby lock said eccentric against movement, and in turn be locked by the eccentric against movement, in the manner and for the purposes, as will hereinafter appear. The eccentric I is pivoted to the carriage above and to one side of the pivotal point of the lever f, and preferably on a vertical line passing through the center of the tackle. The said eccentric is provided with two shoulders or notches, t and j, adapted to engage the end of the lever f when the latter is in open and closed adjustment, respectively. A link, 7 5 K, is pivotally secured at its lower end to the eccentric I at a point, It, located about halfway between the pivotal point of the eccentric and one end thereof. The link K passes upwardly through a slot, L, in the carriage, and is provided at its upper end with a laterally-extending lug or lugs, Z, which latter are adapted to engage an inclined groove or inclined grooves, m. The groove or grooves m are formed in the side or sides of a stationary block, M, secured to the under side of the carriage-way A, and consist of an incline in the form of an open inverted C.

In the position represented in Fig; 1, full lines, the tackle is supposed to be attached to 0 a fork-load of hay, and the same is being elevated. The carriage is now held against motion on the way by means of the link K, which is prevented from being depressed as long as the notch t on the eccentric 'rests in contact 5 with the end of the lever f, and because of the downward direction of the grooves with which the upper end of the link is in contact the carriage cannot be moved without depressing the said link. As the tackle is elevated the upper end of the loop (1 passes between the lower end of the lever f and the stationary projection f, and strikes against the end of the arm h, lifting it upwardly, and thereby closing the lower end of the grip-lever into contact with the projection f within the loop. This action of the grip-lever sets free the eocentric, allows the link to move down the incline, and the carriage being now free to move will respond to the pull on the hoisting-rope, force the link down the incline, rotate the cocentric into the position represented in dotted lines, Fig. 1, and thereby lock the grip-lever in closed adjustment, as shown, the upper end of the lever f engaging the notch j on the eccentric. The carriage is now moved on the way without liability of releasing the load until the upper end of the link K comes in contact with a second incline over the point where it is desired to deposit the load. The link, as the carriage moves on, will be drawn up this second incline, unlock the upper end of the grip-lever from the eccentric, release the tackle with its load, and stop the carriage, since the moment the lever f releases the tackle its upper end engages the notch t on the eccentric and prevents the link from further motion down the incline. The return-of the carriage for another load is a repetition of the operation just explained.

One of the several advantages of my pres ent invention consists in the positive action of the locking device, by which the annoyance often caused by the clogging of gravity de vices is entirely avoided. Furthermore, the arrangement of the link, incline, and. eccentric is such that the carriage is not brought to an abrupt stop, and the several parts are saved from sudden shocks and damage.

It is evident that slight changes may be made in the form and construction of the several parts without departing from the spirit and scope of my inventionas, for example, the eccentric might be of many shapes different from that shown and yet perform the same function; hence I do not wish to limit myself 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 and carrier, the combination, with a grip-lever pivoted to a carriage and a projection rigidly secured to said carriage, of an eccentric bar or plate having two shoulders thereon, with which the lever engages, a stationary incline, and a link eonnected to the eccentric and adapted to engage I the incline, thereby locking the lever in open adjustment and stopping the carriage, substantially as set forth.

2. In a hay elevator and carrier, the combination, with a carriage, a projection secured thereto, and a grip-lever pivoted to a carriage, and adapted to be closed by the action of a movable tackle, of an eccentric bar or plate having two shoulders thereon, adapted to engage the lever and respectively hold the latter in closed and open adjustment, a stationary incline, and a link pivotally secured to the eccentric and adapted to engage the incline, whereby the lever is locked in closed adjustment and the carriage released, substantially as set forth.

3. In a hay elevator and carrier, the combination, with a carriage, a grip-lever pivoted thereto, and an eccentric bar or plate having shoulders thereo11,which latter engage the upper end of the lever, of a sliding link connected with the eccentric, and adapted to engage an incline secured to the carriage-way, whereby the reciprocating motion of the carriage imparts a positive rocking motion to the eccentric, substantially as set forth.

4. In a hay elevator and carrier, the combi nation, with a grip-lever adapted to be opened and closed by the downward and upward pressure of a movable tackle, of a notched or shouldered rock bar or plate located above the lever and adapted to engage the upper end of said lever, a stationaryincline, and a link pivotally secured to the rock bar or plate near one end of the latter, the link being adapted to engage the said incline,a nd thereby operate the rock bar or plate, substantially as set forth.

5. In a hay elevator and carrier, the combination, with a carriage and a rock bar or plate located near the upper end of a grip-lever, and provided with two notches or shoulders on one side for engaging the end of the lever, the plate and lever being pivotally secured to the carriage, of an operating-link pivoted to the rock-bar near one end of the latter, said link being held against lateral motion by passing through a slot in the carriage and caused to move vertically in the slot by an incline, substantially as set forth.

In testimony whereof I have signed this specification in the prcsen cc of two subscribing witnesses.
