HAY ELEVATOR AND CARRIER.

SPECIFICATION formingpart of Letters Patent No. 274,317, dated March 20, 1883,

Application filed February 17, 1883. (No model.)

To all whom it may concern:

Be it known that I, EDWINL. HALL, of Deavertown, in the county of Morgan and State of Ohio, have invented a new and useful Improvement in Hay Elevators and Carriers; and-I do hereby declarethat the followingisa full, clear, and exact description of the same.

My invention relates to hay elevators and carriers of that class in which the hoist-ingrope is suspended from a carriage or truck whichrnns or slides on a track to convey the load, after it is hoisted, to its place of deposit.

In elevators and conveyors of this class, when used in barns,-the track, consisting of wooden beam or iron bar or rod, is ordinarily extended across the floor or wagon-way and over the bay or scaffold on each side, so that the hay, when unloaded from the wagon, may be conveyed either.to one side or the other. Withthe track so arranged ithas been necessary, as the trucks have heretofore been constructed, whenever the scafi'old or bay on one side had been filled, orfor any other reason it was desirable to shift the discharge from one side to the other, to reverse the truck upon the way or track and to shift the ropes to corresponding position on the other side. This has always been a matter of great inconvenience, since it. required climbing to the central part of the track over the floor in order to reverse I is the better carried into effect. 45

In the accompanying drawings, Figure l is a side elevation of my improved apparatus. Fig. 2 is a central longitudinal section of the truck, with the way in side elevation. Fig. 3 is a bottom View of the truck. Fig. 4is a section on line 00 w of Fig. 2. Fig. 5 is a transverse section on line 3 y of Fig. 1. Fig. 6 is a bottom view.of the truck with the turntable removed.

In these drawings, A represents the track or way, which may be of any suitable material and suspended by any suitable means. As shown, it is a beam suspended by rods and rectangular in cross section. The truck B runs upon this, having overlapping flanges b I), which bear upon the upper side of the beam, with or without rollers to lessen friction. The space a between the flanges permits the truck to pass the suspending-rods. In the bottom of the truck is a chamber, a, in which are pivoted two levers, d d. The outer ends of these are bent upward, so that when the inner ends lie upon the bottom of the chamber the outer ends are raised to engage with blocks econ the under surface of the track. The inner ends of the levers are cutaway and lap,as shown atf, Fig. 4., these inner andlapping ends fallingjust over the hole 9 in the bottom of the truck, where the stem of the hoist-bloclcenters from below.

It will be observed that the outer ends of the levers engage with the blocks 0 e on theirinner faces,and thus lock the truck against movement in either direction. This locking takes place automatically in the apparatus, when the truck reaches its proper position over the load, by the action of the inner weighted ends of said levers. These inner ends of the levers are raised by the stem h of the hoist-block,as explained, when the said block has been raised itsfull height and locked to the truck. The locking of this stem of the hoist-block is effected by means of pivoted jaws is k in a recess in the truck, and under the ends of thetwo levers. Thejaws are fitted to receive and hold the head 1 of the block-stem. They are pressed together by means of a spring, m, and opened by a lever, n, pivotedbetween the ends 0 0 ot' the jaws, so that motion of the lever at either way will separate the jaws and release the block. This motion of the lever nis effected by means of a bracket, D, on the track, which the bottom of the truck, under the center of 7 projects downward into the path of the end of the lever n, so that the said levermay he turned aside as the truck moves past the bracket, but which still permits the lever n to slip by. Vhichever way, therefore, the truck. moves, it will cause the lever n to strike the bracket and release the block, and in that position it sired point. A weight (not shown) on the free remains until the load is raised to bring again the block-stem to the jaws. Of course the stops on the way or track are set in proper relation to the bracket, so that the bracket will move the lever n and release the block when the truck is in proper position to allow the block and fork to descend to the load or operator.

Underneath the truck is the turning-plate E, to which the rope p is attached, and which also carries the pulley q. This plate is held to the under side of the truck by overlapping cleats 1' r. A hole, 8, registers with thejaws, and is preferably flaring torecei've and guide the conical or tapering end ot the stem. The rope 19 is attached to one side and the pulley q to the opposite, the rope passing through the moving block t, and thence to the pulley q, and thence to an ordinary pulley attached by ordinary clamp to a rafter or other support. It will be apparent, therefore, that in order to 7 reverse the truck and shift it from one side to the other it is only necessary to detach the rafter-clutch (which is ordinarily done with a pole, requiring no climbing) and to shit'tand attachments and the truck may be greatly varied in shape and details. Forexample, it may be in the form of a swivel and the clutch devices modified to fit this construction. I do not limit myself in this respect, provided a suitable swiveled or turning device be attached to the truck, in connection with suitable stops and clutch for the support of the block.

I provide, also, in connection with the hereinbetore-described devices, means for returning the truck from one or either direction. This consists of a pair of horizontal sheaves, 1 1, in a cross-bar, u, on the bracket, through which runs a rope, 2, connected to the truck and passing through a pulley placed at any deend brings back the truck alike from either direction.

It will be understood that any suitable hayfork may be attached to the lower end of the moving block.

The device may of course be used for hoists ing and conveying any kind of merchandise.

Having thus described my invention, what I claim is l. A hay elevator and carrier consisting of a truck and suitable way, stops to arrest the truck properly over the load, a hoisting-rope and pulleys, suitable catch to take hold of and retain the loaded fork when elevated, suitable releasing devices, and a reversible connection between the pulley and rope attachment and the frame of the truck, whereby the rope is I connected tothe truck reversibly, substantially as described. ,g

2. The way B, extending over the floor to either side, a moving truck, an automatic catch adapted to hold the truck in place and to be released by the movable block, a clutch for automatically catching and holding the block, and means for releasing the same, a turning device attached to the under side of said truck, and provided with a rope and pulley attached thereto, whereby the movement of the truck may be made in either direction, substantially as described. I

3. The combination of the truck 13, pivoted levers lapping over clutch and weighted on inner ends, the pivoted jaws, the spring and opening-lever n, and the turning-plate and pulley and rope with movable pulley having headed stem, substantially as described.

4. The combination of the truck having devices whereby it may be moved either way without turning said t-ruck,and bracket on the way, provided with sheaves, and a cord passing between said sheaves and attached to the truck, a pulley, and a weight, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWIN L. HALL.
