HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 318,085, dated May 19, 1885.

Application filed October 4, 1884.

To ctZZ whom it may concern.-

Be it known that I, MARoUs -W. CHAMBER- LAIN,2L citizen of the United States, and a resident of Branchville, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Hay Elevators and Carriers, of which the following around and upon which the operating-rope is made to work, and which are made with fixed journals secured thereto or integral therewith, in slotted journal-bearings so formed in the frame that while the loaded pulley is held in position while performing its office it may be readily removed from its bearings in the frame. The pulley-wheels are made interchangeable the one with the other in their respective bear- 2 5 ings.

My invention furthermore consists in pivoting the bolt-plate upon a loose pin resting in vertical grooves or slots in the frame, and in making the opening through the plat. e larger 3 than the pivotal pin, so as to allow a slight play or rocking of the plate upon the lockinglugs before the plate begins to revolve upon its pivot.

In the accompanying drawings, Figure l is 3 5 a side elevation of a hay-carrier mounted upon a track, the frame being broken away in places to illustrate my invention; and Fig. 2 is a partly-sectionalview of the slotted j on rnal-bearing.

A is the carrier-fram e, mounted upon a trackrail, B, and is provided with wheels or rollers resting on said rail.

0 D are the pulley-wheels over and around which the operatingrope K is passed. This rope K is in all ordinary cases secured by one 5 end to one of the pulleys, as at O, andispassed from there down around a pulley, E, mounted in a bail, I, to which the load is attached, and which serves, as hereinafter described,to secure the load in its elevated position. The pulleys G and D are fixed. upon their shafts or (No model.)

journals, and upon the inner faces of the frame are formed sockets or j ournal-bearings F, open toward the top, so that when it is so desired the pulleys may be removed from their bearings, and the pulleys being of the same form and size, they may be changed about from end to end of the frame. The bolt-plate G is mounted in the central part of the frame in suchposition that the locking hooks or bolts formed upon its lower sides will be in position to pass through the bail I when it is passed into the frame A. This plate is mounted upon a pin, H, which is itself mounted in vertical slots or grooves upon the inner faces of the frame A, so that it mayhave a limited vertical movement, but no movement from side to side. The opening in the plate G through which the bolt or pin H passes is enlarged laterally, so as to allow a limited side movement of the plate before it begins to rotate on its bearings,and this is found to greatly assist in moving the plate when it rests upon the locking lugs h 71, upon which the plate rests when the load is suspended therefrom. The stop-block L is secured to the track B in position to en- 5 gage the vertical slot in the upper side of the plate G, and when the bolts upon the under side of G are in position to allow the entrance of the bail I, and resting with their ends against the locking-lugs M, the block L serves to hold the frame A in position. S0 soon,however, as the bail I enters the frame and presses up on the plate, the carriage is free to more, and such movement will cause the plate G to rotate and pass one of its bolts through the bail I, and thus secure theload to the carriage.

When it is desired to free the bail I, with its load, from the carriage, the lateral move ment of the plate G upon its pivotal pin, by reason of the laterally enlarged opening through said plate, will greatly decrease the frictional contact of said plate with the lugs 71, and allow a ready withdrawal of the boltplate from said bail.

Having described my invention, what I claim is- 1. In a hay elevator and carrier, the combination, with the carriage and the pulleys mounted therein, of the slotted journal-bearings F, formed within the frame, and adapted ICO 10 ing through a laterally-enlarged opening in the plate, substantially as and for the purpose set forth.
