-HAY SLING 0R FORK RETURN.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed April 30, 1913. Serial No. 764,642.

To all whom it may concern: I

Be it known that I, HAROLD L. WVINsoR, a citizen of the United States, residing at Butler, in the county of Bates, State of Missouri, have invented certain new and useful Improvements in Hay Sling or Fork Returns; 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.

The present invention is directed to improvements in loaders, and more particularly to one for loading hay.

The invention has for its object to construct a device of this character which after discharging its load will be returned automatically toits loading position.

A further object of the invention is to provide a device of this character which is exceedingly simple in construction, efficient in operation, and one which can be manufactured at a small cost.

lVith these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a view showing the hay sling or fork in a position to unload the hay. Fig. 2 is an enlarged front view of the drum and reel. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 1 is a similar view on line 4=1 of Fig. 2. Fig. 5 is a similar view on line 5-5 of Fig. 1. Fig. 6 is a similar view on line 66 of Fig. 1.

Referring to the drawing, the numeral 1 designates a pair of spaced posts, the upper ends of which are connected by a bar 2, and supported by said bar is a pair of pulley blocks 3 of the usual construction. One of the posts 1 is mortised, as at 4, for receiving the bracket 5, said bracket being bolted in the mortise and provided with bearings 6 for rotatably supporting the shaft 7. Fixed to one end of the shaft 7 is a reel 8, which consists of circular side plates 9, the same being held in spaced relation by the bolts 10, to one of which is connected one end of the rope 11. The rope 11 has connected thereto a hay sling or fork 12, of any well known construction. The rope 11 passes over the pulley 13 carried by the carriage 14:, the same being adapted for travel backwardly and forwardly upon the track 15, said track being shown in this instance as suspended in a barn or a like structure. The rope 11 thence passes through the pulley block 16, which is suitably supported in the barn. It will be understood that the rope 11 has one of its ends equipped with a draft appliance so that an animal can be attached thereto for pulling the rope 11 and fork 12.

Fixed to the shaft 7, and between the bearings 6 is a drum 17 which has its periphery provided with spiral grooves 18 which are continuous, said grooves at their inner terminal being contracted, as at 19, so that the same opens upon the minor end, of the tapered integrally formed drum 20, the major end of which being provided with spaced flanges 21 which form guideways for the brake shoe 22, which is pivotally mounted for contact with the drum 20 be tween the flanges 21, said brake being used in case it is desired to limit the rotary movement of the drums.

A cable 23 is provided and has one of its ends connected to the hook 2 1, said hook being attached in the outermost groove 18 of the drum 17. The cable 23 is adapted to wind or unwind in the groove 18, and when winding thereon the same will finally engage the contracted terminal and will then wind upon the tapered drum 20, during which time the weight 25 will be elevated through the medium of the pulley blocks 3, around which said cable is trained. It will be of course understood that when the cable 23 is winding upon the drums 17 and 20 the rope 11 is unwinding from the reel 8, which action imparts rotary movement to said drums. The weight 25 is preferably formed from a rectangular casing 26, in which sand or the like may be placed and the lower end of the cable 23 is fixed to the removable cover 27 of the casing, as clearly shown in Fig. 6.

When the draft animal draws upon the rope 11, the same will move the fork 12 upwardly until the same engages the carriage 1 1, and continued strain upon said rope will cause the carriage to travel upon the track 15, and to the point where it is desired to release the load of hay from the fork. During the movement of the rope 11, the reel 8 will be rotated as the rope unwinds therefrom, and during this time the cable 23 will be winding upon the drum 17, which being greater in circumference than the drum 20 will exert greater pulling force upon the cable 23 so that the loaded fork will be elevated until it contacts with the assuage 14,

and at which time the weight 25' isyelevated' proportionately. Upon continued strain less power is necessary to move the carfiag'e' 14 as the same travels upon the track 15 with the fork 12 in eega emem; therewith. After' strain has been released from the rope 11,-fthe' w'ei g'ht' 2'5 willdescend, which causes the rope 11 to wind uponthe reel and the cable 23 to unwind first from the drum 20 and then from the drum 17, thereby causilig the ro e 1 1 to return the carriage 1 4; and the grapple 1 9) to their operative or loading position, as shown in Fig. 1.

It will be' apparent that by forming the drum 1 7 and drum QQ iin the mainirer' described the cable" 23 will be unwinding from the drum 20" when the least power is requi regil to return the carriage to the point on the trackat whichthe fork or sling startsto descend, and that when the most power is necessary the cable will have passed from the drum 20 and will be unwinding 'from the drum I7, and at which time the zfork or sling will be descending from the track to the load of hay.

upon the rope 11, the cable 23 will wind upon the tapered drum 20, at which time a bracket, hearings mounted upon the bracket, a shaft revolubly mounted in the What is claimed is A device of the class described comprising bearings, a reel fixed to one end of the shaft, a drum fixed to said shaft, said drum ha ing a spiral groove formed therein, one end of which terminates in a contracted groove, a second drum formed integral with the first named drum and being tapered with its minor end adjacent the first named drum, and in contact with the contracted groove of the other drum. r

testimony whereof, I affix my signature, in the presence of two witnesses.
