LEWIS W. DELP, OF PEOlEtIA, ILLINOIS.

HOlSTlNG-MACHINE.

SPEGIFICATION forming part of Letters atent No. 736,234, dated August 1 1, 1903.

Application iiled January 22, 1903. Serial No.140.194. (No model.)

have invented a new and useful Hoisting- Machine, and particularly a Machine to Recall a Hay-Carrier to the Loading-Point, of which the 4following is a specification.

My invention relates to improvements in i hoisting-machines, particularly a machine to recall a hay-carrier to the loading-point Wh en unloaded, in which two drums and two ropes, being set in motion by Weights, work in conj unctiong and the objects of my improvement are, iist, to provide a combination of machinery to recall a hay-carrier to the loadingpoint when unloaded; second, to provide an easy-working machine which will add small weight to the loaded carrier as it is pulled to its place of destination; and, third, to reduce the speed of the reverse action of the machine gradually until it has brought the carrier back, (and thereby prevent injury to the carrier.) l attain these objects by the mechanism illustrated in the accompanying drawings, in

Figure l is a detailed view of theentire machine When carrier is ready for loading. Fig. 2 is also a detailed view of the machine, showing machine when carrier is pulled to its destination, being set to recall thecarrier when unloaded.

Similar letters refer to similar parts throughout the several views.

The pieces of wood a; @c a; fastened togetherby bolts, form the framework of the machine.

d d is an iron shaft secured to the pieces of frame 0c m and to the center piece of frame by means of holes inframe t t t. On'this shaft d d, to the left of the center of the machine, is fastened a twenty-four-inch wood drum A, around which coils the rope G, one end of said rope G being secured to drum A and the other 'to the carrier on, the track, and to the right of the center of the machine on the same shaft CZ cl is fastened the eightinch Wood drum B, around which coils rope H, one end of which is secured to drumB, and on the other end is fastened the Weights o U2 o3 U4 e5 '06, which set machine in motion.

S S is a post extending from the ground to the carrier-track at the top of the barn. The machineis fastened on the post S S by means of bolts through the frameV of machine and through the post.

u, u are iron rods fastened to the lower part of the frame and extending parallel to each other and parallel to the post S S to the ground, where they are firmly fastened.

t t2 t3 o4 U5 U6 are adjustable iron weights having each a circular hole fm m mm m m in the center, through which the rope H works; also, having circular holes n n n, n n n in the ends thereof, through which pass the iron rods u u.

c c are iron chains suspended by ropes r r and fastened to each of the weights o' u2 o3 o4 v5 o6 in holes n n n n n n. Veights o' 112 o3 U4 t5 @s are fastened to chains c c at desired distances apart. p p are pulleys fastened to frame through which work the ropes r fr.

c is an iron cleat on which is fastened the ends of ropes r r.

The way this machine works is this: As thev loaded hay-carrier, attached to rope G, is pulled along the track to its destination the rope G uncoils from drum A, turning said I drum, thereby turning the shaft CZ cl and drum B on said shaft and winding up on drum B, rope H thereby pulling up Weights QJ Q12 v3 o4 v5 lv attached to said ropes, thereby setting the machine for reverse action. When the haycarrier is unloaded, the weights, dropping, set in motion drum B, which turns shaft ol d, thereby turning drum A and winding up on drum A rope G, and brings back the hay-carrier to the loading-point. As the machine reverses and the chains c c are lowered the weights stop, respectively o' o2 o3 @41;5 v6, as the chains are lowered the full lengths between the weights. As they stop in their respective places they each lessen the speed of the Inaon which the weights are fastened, and the chains may be lowered or raised to suit the length of the carrier-track, higher for a long track and lower for a short track.

What I claim as my invention, and desire to secure by Letters Patent, is-

sired, and which lessen the speed of the Inachine, all substantially as above set forth.

In testimony whereof I have signed my name to the speoifioation'in the presence of two subscribing witnesses.
