LUOIUS E. MILES, OF FULTON, WISGONSIN.

HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 233,633, dated October 26, 1880.

Application filed August 27, 1880.

T 0 all whom it may concern Be it known that I, LUCIUS E. MILES, of Fulton, in the county of Rock and State of Wisconsin, have invented a new and useful Improvement in Hay Elevators and Carriers, which improvement is fully set forth in the following specification and accompanying drawlugs.

My invention relates to improvements in hayelevatin g machines for unloading hay into barns or on stacks, by which a car on rollers and operated by ropes and pulleys is used to elevate and carry the hay to any point desired, said car being suspended under a beam or runway, depositing the hay wherever desired by means of a snatch-rope attached to a harpoonfork of the usual kind. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation. Fig. 2 is a perspective view of the car detached. Fig. 3 is a view of the loose pulley and block, Fig. 4 of the hinged grappling-hooks, and Fig. 5 of the pawl for opening the hooks and holding the car.

Similar letters refer to similarparts throughout the several views.-

The machine may be attached to the ridgepole of a barn or to a beam provided for the purpose, under which it is suspended by hooks on the under side of the beam to enter staples in the upper side of the runway B, said runway-beam being about six inches wide and two and a half inches thick and any length desired. At each end of said beam are pulleys a a. Staples are set crosswise on the upper side of said beam in range with said pulleys, so that the draft-rope, passing over the pulleys, will run freely through said staples.

The car 0, Fig. 2, is suspended under the runway-beam by iron straps b 1), extending up above the runway, to receive the wheels or rollers 1 2 3 4 in their upper ends,to carry the car upon the runway-beam, and passing entirely around under the same. The car is made in two parts, having an open space between the parts, in the center of which is located a pair of hinged grapplinghooks, Fig. 4, for engaging and holding the loose pulley, Fig. 3. These hinged grappling-hooks are pivoted to crossbars 6 6, extending across the two parts of the car. On the forward end of said car is a pul- (ModeL) ley, 01, over which passes the draft-rope. Said draft-rope is attached firmly to the rear end of the car at g, and passes through the loose pulley, and thence up over pulley d in the forward end of the car; thence running along under the runway-beam to its farther end up over pulley a; thence back along the upper side of the runway-beam through the staples to the other end of said runway; thence down over pulley a to a pulley suitably arranged for connecting the power.

At the rear of the car is attached a weightrope, which passes over pulley f, located near the rear end of the runway on its under side,

to which rope is to be connected a weight to draw the car back to its original position after the fork is released.

The pawl, Fig. 5, is pivoted at its rear end near the end of therunway, and passes through a rest, 9, located about a quarter of its length from the rear end, which rest also serves as a bumper or stop for the car. The forward end of the pawl is wedge-shaped, so that when the car is brought back to its place the wed ge-shaped point passes between the hinged grapplinghooks, opens them, and releases the pulleyblock which carries the fork, so that the latter will descend down to the load below. To insure the opening of both parts of the grapplin ghooks at the same time, a groove is made longitudinally on the under side of said pawl from its point, so that the top of the pulleyblock, which is sharpened, will slide in said groove and open the grapples each side alike; also, on the under side of said pawl, at its forward end, it is provided with a catch, a, which runs over a bar, h, in therear part of the car, thus serving as a detent for the purpose of holding the car to its place until afork-load of hay is elevated to it and said car is ready for motion.

.When the head of the loose pulley-block is run up and slipped into the grapples it strikes the under side of the pawl, thus raising it, so that it is unhooked from the bar h, and the car is then released.

I do not use any particular kind of fork, as any may be attached to the loose pulley, and is independent of the car in its operation, and any fork may be used which experience proves to be the most suitable.

What I claim, and desire to secure by Letgrappling-hooks attached to said car, a de- 10 ters Patent, istachable pulley-block provided with a pointed The combination, with beam B, provided head, and suitable draft and weight ropes, subwith pulleys a and pawl-rest g, of a pivoted srantially as shown and described. pawl attached to said beam, and provided with a Wedge-shaped or pointed head having a LUOIUS MILES groove on its under side, the ear 0, adapted to Witnesses: run upon said beam,andhavingabar, It, for the ED. 1?.
