HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 483,845, dated October 4, 1892.

Application filed January 22, 1892. Serial No. 418,928. (No model.)

To all whom it may concern.-

Be it known that I, NORMAN IsAoHsoN, a citizen of the United States of America, residing at Marion, in the county of Cassia and State of Idaho, have invented certain new and usefullmprovements inHay-Carriers,of which the following is a specification.

My invention is a hay-carrier of that type which is provided with wheels to run upon suitable ways and with lockin g devices to antomatically engage the load as it is lifted and to automatically disengage the load or the empty fork at the desired point.

The invention consists in the locking devices and in the means or operating them, these means including a ring or collar fixed to the way.

In the accompanying drawings, Figure 1 is an elevation of a carrier embodying my invention with one side removed. Fig. 2 is a bottom plan view. Fig. 3 is a detail view of the locking-slide.

In the figures the working parts are inclosed between side plates A, which terminate upon the bottom thereof in a bell-shaped mouth, as is usual in such carriers. Pulleys a are journaled in bearings in the said side walls at each end of the lower edge, and these receive the loops of the hoisting-ropes B, one end of the rope being secured to the carriage The pulley-block O is carried in the loops of the hoisting-ropes and is provided with two pulleys, the lower one larger than the upper, so as to increase the power in lifting and at the same time permit the load to be lifted steadily without twisting the hoisting-rope. The frame of the pulley-block holder is provided with a hook at its lower end for engagement with the hay-fork, while the upper end is pointed and is provided with a lateral opening or eye passing through the same in the direction of the length of the carrier. A looking and holding slide 1) is adapted to slide upon flanges 0, turned in on the lower edge of the side plates of the carrier, the line of movement of the said locking-plate being back and forth across the entrance of the opening in the upper part of the bell-shaped mouth. The slide has a central tongue 00, which is adapted to pass through the opening in the pointed extension or of the pulley-block frame, and

thus hold it and its load to the carrier, and has also side extensions in lines parallel to the the tongue, and these bear in upon the turnedin flanges of the frame and serve to support and sustain the slide and the load. The side extensions are shown at d.

In order to relieve the tongue 0:: from the full weight of the load, I extend a cross-bar 6 between the side plates of the frame, and upon this cross-bar the free end of the tongue rest-s when in its extreme position to the right,

and thus there is no danger of the tongue being ruptured by having one end unsupported.

In order to prevent the accidental withdrawal of the locking-slide, I form a groove 6 on the under face of each extension d, near the ends thereof, and this engages with a slight rise in the guidefianges of the frame, and thus some little pressure is required to withdraw the slide.

I have shown the carrier as running upon a cable; but it will be understood that it may be as readily applied to the tracks used in many instances in place of the cable. Secured to the cable or track at the end of the way by means of a set-screw I place a collar, which consists of a cylindrical plate having an annular opening with a beveled edge, and this is adapted to receive the latch f, which engages the beveled edge 9 of the collar It. By making the collar cylindrical it will be seen that the latch of the carrier will always engage with it, even though the carrier has a swinging movement as it reaches the end of the way, and there is a decided advantage in havinga stop and catch which entirely encircles the way rather than a simple projection directly beneath the track, which only engages with the latch of the carrier when directly in line therewith. The carrier-latch extends to the opposite end of the frame, where it is pivoted at 'i, and has a cam-shaped portion 70, which has a locking -notch Z. A combined lever and dog m, pivoted at n, with its front end extending over the opening of the bell-shaped month has its rear end engaging the notch, and while thus engaged the latch cannot be lifted, but will be kept in engagement with the collar at the end of the way. The lever at has an upward extension 0, and when the pulley-block is elevated the upper end thereof passes through the bell-shaped mouth and lifts the lower end of the lever m, which releases the opposite end from the notch Z, while the extension 0 elevates the latch and frees it from engagement from the holding-collar. The lifting of the lower end of the lever m has another effect-namely, to operate the locking-slide so as to advance it to engage with the pulley-block holder and hold the fork and its load in its elevated position. A bell-crank lever 19 is pivoted at 3 and has one arm directly above the lower end of the lever m, while the other end of the bell-crank engages a slide q. The bell-crank has a downward extension 0", the reduced end of which passes through a slot in the end of the locking-slide, and thus when the end of the lever m is lifted by the end of the pulley-block frame it in turn comes in contact with the horizontal extension of the bell-crank lever with the effect to turn the lever on the pivot and through the downward extension 0 move the lockinglock in g-slide, and-a bell-crank lever connected with the slide and operated by the lever m, substantially as described. 2. In a hay-carrier, a lever m, a locklngslide, a bell-crank connected therewith and operated by the lever m, and a slide for operating the bell-crank, said slide being acted upon by the stop on the way, substantially as described.

3. In combination with the lever m, the bellcrank lever operated thereby, a locking-slide operated by the bell-crank lever, and an unlocking-slide connected with the bell-crank and projecting beyond the frame, a collar encircling the way and concentric therewith, and a latch on the carrierengagrng said collar,.said

' collar presenting a plane surface adapted to form a stop to actuate the: unlocking-slide,

substantially as described.

4:. In a hay-carrier, the combination of a locking-slide having a tongue-00, and; also: hav-- ing side extensions d d grooved on the under faces near the outer ends, across-bar extending between the side plates of the carrierframe for supporting the free end of the tongue, and means for operating; the lockingslide, substantially as described. 7
