HAY ELEVATOR AND CARRIER.

The hay-carrier 2 is The carrier is held stationary and in position l constructed of suitable material and may be while the fork with the hay is being elevated I of either a square or oblong shape. On op-- and until the drawing tension of the ropeand 5o posite ends of said carrier and partly within the compression of said jaws by the entrance of said adjustable ball on the hay-rope releases the same from behind said shoulders. The carrier, if desired to be changed in the direction of travel, may be done so by simply withdrawing the operating-rope from one pulley and shifting to the one in the opposite side of the casing, the catch and trip on the bottom of the track being of course correspondingly changed.

In operating my improved hay-carrier upon the track I avoid, as previously stated, the objections of having the horse pull directly on the hay-rope and then back, slackening the rope and tangling oftentimes and dragging in the mud by the use of a hoisting-jack 19. This jack is placed in a convenient position for operating the hay-carrier, and is constructed upon suitable frame-pieces 20. Upon said frame is secured a shaft 21, provided with suitable bearings and on one portion of which is loosely mounted a drum 22, around which the hay-rope is designed to wrap and unwrap, according to the movement of the haycarrier, passing therefrom to the said spool under the customary ground-pulley 23. A clutch 24, normally closed by a spring 25, is also mounted on said shaft and is controlled by a lever 26, secured to the jack-frame by a bracket 27, and is operated by a cord 32, pass ing .over pulley 27*, attached to upright 28, secured to said frame. The clutch is designed to revolve said drum and wind the hay-rope thereon to hoist the hay-fork to the carrier and carry the same to the position desired, and to be thrown out of engagement with said drum when the carrier is being returned to its loading position, thus allowing the drum to revolve independently of the jack-gearing as it pays out ,the hay-rope, being held in check in its revolution by a spring-actuated brake 29, secured to the frame of the jack. The shaft 22 is provided with suitable gearing 30 to regulate the speed of said spool, and which is connected with an ordinary sweep horse-power 31, by which motion is communicated to the Whole machine and carrier. The operation of my invention is now thought to be apparent. The hay-fork in the end of the hay-rope having received its load is hoisted. up by the winding of the rope on the hoisting-spool and is held in an elevated position by the adjustable ball on the hay-rope becoming locked within the locking-jaws of the carrier. The drawing tension of the hay-rope and the entering of the said ball within the carrier releases the upper ends of the lock ing-jaws from the shoulders on the converging strips beneath the track and permits the carrier to be conveyed to the proper place, where the fork is tripped and discharged of its load. The clutch on the jack is now released from engagement with the windingspool and the carrier is drawn back to its original position; but when the extended arms of the locking-jaws enter the flaring mouth of the converging strips and are compressed together the ball is released from the lower locking ends of said jaws and the fork dropping down to be loaded up again and the operation repeated, as described.

Having described my invention, What I claim,and desire to secure by Letters Patent,

In a hay elevator and carrier, a suitable hoist, a track provided on its under side with converging strips having a flaring mouth and shoulders, a carrier provided with integral bracket-arms carrying rollers to engage said track, twin jaws pivoted Within saidcarrier and having extended portions projecting beyond the top of said carrier and said jaws also having arrow-head portions forming a flaring opening and lockin -shoulders, triangular and beveled blocks secured within the carrier at the bottom between the ends of said pivoted jaws, leaf-springs secured. to the outside of the carrier, provided with an inwardlyextending right-angular portion projecting through said carrier and abutting against said pivoted jaws, pulleys journaled in opposite sides of said carrier, and a hoisting and operating rope provided with an adjustable locking-ball, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ELI J. GILPIN.
