HAY-UNLOADER.

SPECIFICATION forming part of Letters Patent No. 226,457, dated April 13, 1880.

v Application filed February 1S, 1880.

To all whom t may concern l Beit known that I, FRANK PATRICK, of Brownville, in the county ot' Jefferson and State of New York, have invented certain new and useful Improvements in Hay-Unloaders; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertai-ns to n ke and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

Figure l is a side elevation. Fig.2 is a longitudinal vertical sectional view. Fig. 3 is a view, in perspective, of the car and track. Fig. 4 is a detail view, and Fig. 5 is a view of the sling detached.

Corresponding parts in the several figures are denoted by like letters of reference.

Thisinvention relates to hay-unloaders 5 and it l:onsists in certain improvements in the const iction of the same, which will be hereinaft fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A represents the track, which consists of two parallel beams, B B, united by bails or brackets C C in such a manner' as to be held some distance apart, as clearly shown in the drawings. The lower ends of the brackets are bent to form shoulders, upon which the beams rest. The bails or brackets C hang upon staples D, one of which is secured to each pair of rafters of the barn, the ends of the staples passing on either side of the rafters and through a metal plate or washer, E, upon the upper side of which they are secured by nuts F.

Gris the car. rIhis consists of a metallic frame, the two upper corners of which are provided with rollers or casters H, adapted to run upon the track.

I I are pulleys arranged in the lower corners of frame G, and centrally under the frame, between the pulleys I I, is hung a` pulleyblock, J. K K are brake-levers pivoted centrally in frame G and extending to and bearing against the pulleys I I, respectively. The outer ends of said levers are provided with transverse cross-bars L.

M is the draft-rope. One end of this is sepasses over the pulley in block J, under the pulley in block N, under the pulley in a loose block, O, and over one of the pulleys I at the corners of frame G. From thence it passes over pulleys suitably arranged at the ends of the barn to the point where the team is to be attached. l

The free end of the draft-rope M is provided with a hook, H2, by which it maybe connected to one of two small ropes or cords, P P, oneI V V are slides attached to the legs of the bail R and arranged to cover the notches T. It will be seen, however, that the said notches at either end of the frame may be uncovered, which may be done by rocking the bail It by means of suitably-arran ged cords W W attached to the upper end oi' said bail.

X is the sling, which consists of two parts, Y Z, each consisting of a rope, which is doubled and provided at its central or doubled portion with a hook, A'. The ends of the rope Y are provided with the latch-boxes B', which con- Sist of suitably-shaped castings, having longitudinal openings O', in which are placed springs D', working against bolts E', the front ends of which are beveled, as shown. The sides of the castings B' have openings F', and .at their rear ends they have suitable bearings for the pulleys Gr'.

H' H' are ropes attached to the latch-bolts, passed over the pulleys, and connected to each other and to a triprope ,1'. To each end of the rope Z are attached the catches J', which consist simply of plates provided with laterallyprojecting studs K'. In operation said plates enter the latch-boxes, the studs K' passing into the openings F', where they are kept by the beveled bolt, which, by the spring, is forced forward between the plates. The parts of the sling which are in this manner connected may IOO be disconnected by pulling the trip-rope, thus drawing the bolts back and permitting the catches J' to withdraw from the latch-boxes. Rods L' are employed to space the sling-ropes, as shown.

From theforegoin g description, taken in connection with the drawings hereto annexed, the operation of my invention and its advantages will be readily understood.

In loading the wagon the sling is placed in the bottom thereof in such a manner as to encircle the whole load. 0n reaching the barn the wagon is driven nnde'r the ear, which is held in position by the cross-bar L upon one of the brake-levers engaging one of the notches T in frame Q, where it is held safely by the slides V. The ends of the sling are then hooked into rings or eyes at the lower ends of the pulley-blocksN 0, which now, by applying power to the draft-rope, are elevated with the load to any desired height. The car is now released from the notch T in frame Q by operating bail R so as to withdraw the covering-slide V, and travels along the track until the placeis reached where the load is to be deposited. At this point the load is retained at the proper elevation by one of the brakes K. The parts of the sling are-now disconnected in the manner dewhich the caris returned to frame Q, to be ready for another load.

To reverse the car I proceed in the following manner First, the draft-rope M is drawn out through the several pulleys through which it runs, together with the small rope or cord P, which is at the time attached to its free u end. The said small rope is then detached, and

the free end of rope M is then hooked or otherwise secured to the small rope I? at the other end of the car. By pulling the said (last) small rope the draft-rope is pulled over the pulleys at the end of the car opposite to those over which it was previously adjusted, thus adapting the car to be moved in an opposite direction. f

It should be observed that the small rope P, which remains in one of the pulleys I, is small enough to permit the brake -lever bearing against said pulley to come down far enough to permit its cross-bar L to pass under frame Q, which would otherwise obstruct the pas sage of the car.

Having thus described my invention, I claim and desire to secure by Letters Patent of `the United Statesl. The car consisting of the frame G, having rollers H, pulleys I I, and brake-levers K, having cross-bars L, substantially as and for the purpose set forth.

2. The combination, with the car G, having pulleys I I, and brake-levers K K, with cross bars L L, of the frame Q, having spring-bail R, notches T T, inclined guides U U, and slides V V, substantially as and for the purpose set forth.

3. The combination, with the car G, having pulleys I I, brake-levers K K, and block J, of the draft-rope M, having hook H2, small ropes P I), and pulleys N O, substantially as and for the purpose set forth.

4. The herein-described sling X, consisting of ropes Y Z, having latch-boxes B' B', catches -J J', and operating-ropes H' H', all conscribed, thus allowing the load to drop, after structed, arranged, and operating subst-antially as and for the purpose set forth.

5. The herein-described hay-unloading device, consisting of track A, frame Q, car G, sling X, draft-rope M, ropes I? I?, and pulleys N O, all constructed, arranged, and operating substantially as and for the purpose herein shown and specified.

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

FRANK PATRICK.
