HAY-CARRIER.

SPECIFICATION forming` part of Letters Patent No. 284,269, dated September 11, 1883.

Application filed March 24, 1883. (No model.)

To all whom it may concern.-

Be it known that I, Oscnn LovELAND, a citizen of the United States of America, residing at Adams, inthe county of Jefferson and State of New York, have invented certain new and useful Improvements in Hay-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 appertains to make and use the same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.

This invention relates to transferring hay and sheaf-grain from wagons to the hay-mow or grain-bins of a barn, its object being to enable wagons to be rapidly unloaded with a comparatively small amount of labor.

The improvement consists in certain novel constructions and combinations of devices composing an unloading apparatus, which will be hereinafter particularly described in connection with the accompanying drawings, and its novel features definitely pointed out in the appended claims.

In the drawings, Figure l is a side view of an unloading apparatus constructed according to my invention. Fig. 2 is a section on the line x x of Fig. l. Fig., 8 is a plan view of the sling. Fig. 4 is a detached perspective view of one of the sling-clutcheswith the parts arranged as about to separate.

The letter A indicates a track or rail, provided with suspending rods and hooks c, by which it may be suspended from the rafters or other suitable supports in a barn. Upon this track travels a depending carriage, B, composed of hangers c c c c, arranged in two pairs, secured at the ends and on opposite sides of a connecting-bar, d. The upper ends of the hangers c extend above the rail, and each lhas to its inner side pivoted a wheel, e, which runs upon the upper side of said rail. At one end of the carriage both of the two hangers at that end have pivoted to the inner sides of their lower ends pulleys f f', and at their other end one of thehangers only has pivoted to the inner side of its lower end a pulley, f2.

To the under side of the rail A is secured a lug or catch, g, and to the upper side ol' the bar d of the carriage is secured a spring-latch provided with a notch to engage said catch. In a slot formed in the rail Ais pivoted atripping-lever, z', which is provided at its lower end with projections c, which extend through the rail on opposite sides of the catch g, and

either of these projections may be forced against the latch to throw it out of engagement with said catch by swinging the trip-lever on its pivot. The latch is beveled on both sides of its notch, so that in whichever direcpulley f, or upon the cord which passes 'overV said pulley when the lever is free, and the upper end of said lever is bent to form a short arm, c, which will be struck by the catch g and pressed downward, so that the lower end of the lever 7c will be lifted clear of the pulley f and its cord. L L indicate two double pulley-blocks, provided with hooks If, which are to be attached to the opposite ends of a sling, M, as shown in Fig. I.

N designates a rope, which has one end secured to the end of the carriage B adjacent toA the pulley f, and passes downward through both of the blocks L L, then upward over pulley f, thence over pulley f2, again downward through the blocks L L, and thence over pulley f, and off to a stationary pulley, which may be located at any convenient point.

Referring to Fig. 3, the sling M is composed4 of two parts, m m', connected by clutches p p.

rEach half of the sling in the present instance.

is composed of twocross-bars, q, and four ropes passing through said bars, the outer ends of the four ropes of each part being secured to rings r, but the inner ends of the ropes being connected in pairs to the clutches, respectively. Each clutch is composed of two parts, the first consist-` ing of a block, s, having two slots, s and s2. In the slot s is pivoted alever,s3,whichhas projecting from one side a lug,-s", which is arrangedv to partially close the slot s2 when the lever s3 lies longitudinally in its slot, but will be raised or IOO turned back to open said slot s2 when the lever s3 stands transversely. The block s is Yprovided with bail 85, by which it may be attached to the ropes. The other part of the clutch consists of a tongue or catch piece, s, having one end provided with an eye for attachment to the ropes, and its other end provided with a lateral projection, which is adapted to catch over and engage with the lug s4 of the lever s3 when the end of the tongue is inserted through the slot s2, as shown in Fig. 3. These tongues s6 are attached to the looped ends of the ropes of the part m of the sling, and the other parts of the clutches are attached to the ropes of the other part, m, of the same. To the long arms of the levers s3 are attached cords t, by which said levers may be thrown to a transverse position when it is desired to disengage the tongues and allow the two parts of the sling to separate.

The operation of my unloading apparatus as now described is as follows: The carriage B is run to such position that its spring-latch h will engage with the lug g on the rail, and at th'is time said lug strikes the upper end of the lever 7c and lifts its lower end clear of the pulley f. The carriage being thus held stationary, the loaded wagon is driven under the same and a quantity of hay or sheaf-grain is placed upon the sling, the two parts of which are clutched together. The rope N is then slacked up to lower the double pulley-,blocks L L, and these blocks are hooked to the opposite ends of the sling, which, with its load, may be then raised clear of the wagon by pulling on'the free end of the rope N. The trip-lever i being then swung to one side by means of a cord attached thereto, the latch h will be disengaged from the lug g, and the carriage may then be started to travel on the rail to carry its load to where it is to b e deposited. Immediately the carriage leaves its original position the lever k becomes released from the lug g, and the lower end of said lever falls upon the rope, passing over the pulley f, and binds said rope to prevent its running back over the pulley. When the carriage reaches the point where the grain is to be deposited, the cords t are pulled to turn the levers s3 of the clutches and permit the two Vand its upper end arranged to be pressed downward by the lug g at the same time that said lug engages the spring-latch, substantially as described.

2. rlhe combination, with the rail A, the depending carriage arranged to travel on said rail, and the pulleys, cords, and pulley-blocks connected with said carriage, as described, of

the sling composed of two parts, connected with said pulley-blocks, respectively, and connected together by detachable clutches, essen tially as setforth.

3. The combination, with the sling composed of two parts, m m', of the clutches, each composed'of two parts, which are attached to the parts of the sling, respectively, each clutch being composed of the slotted block-lever s and attached lugs s4, and the tongue s, adapted to engage said lug, substantially as described.

4. The herein-described unloading appara tus, composed of the rail A, provided with the lug g and trippinglever t', the depending carriage B, arranged to travel on said rail, and provided with the spring-latch h, pulleys f, f and f2, and the lever k, the double pulleyblocks L L, the cord N, the sling composed of two parts connected with said pulley-blocks, respectively, and the clutches arranged to connect and disconnect the two parts of said sling, the whole being constructed and arranged to operate as specified.

In testimony whereof I afliX my signature in presence of two witnesses.

OSCAR LOVELAND.
