HOISTING AND UNLOADING SLING FOR WAGON S AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed June 4, 1919. Serial No. 301,784.

North Dakota, have invented certain new' and useful Improvements in Hoisting and Unloading Slings for Wagons and the like, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved hoisting and unloading sling for wagons, carts, cars and the like, particularly adapted for hoisting and unloading bundles of material out of loaded carts, cars or Wagons, and is especially adapted for unloading cane, corn and the like, whereby the material to be hoisted or lifted may be easily and quickly removed, and then easily, quickly and conveniently removed from the sling;

While the design and construction at pres ent illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes,- the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a perspective view of the improved unloading sling constructed in accordance with the invention, showing the sling arranged in the form of a loop, to hold and support the material to be unloaded.

Fig. 2 is a plan view of the sling opened up.

Fig. 3 is an enlarged detail perspective view of the locking means between the opposite sides of the sling;

Fig. 4 is an enlarged longitudinal sectional view through the locking means.

Fig. 5 is an enlarged detail perspective view of the locking bar properof the locking means.

Fig. 6 is a sectional view on line 66 of Fig. 4:, showing the staples connected to the tubular member of the locking means, and between the shanks of the staples the looking bar is capable of movement.

Fig. 7 is an enlarged sectional View of one of the tubular rods, showing one end of the latching or locking bar locked, and the rope attaching member detached.

Referring more especially to the drawings, l designates an elongated tubular rod, and 2 denotes staples, which are fastened to the tubular rod at intervals along its length. The shanks of these staples pass through the tubular rod, and where they pass through the rod they are spaced, as shown in Fig. 6. The end portions of the shanks of the staples are deflected or mashed or swaged as shown at 3, to anchor the ends of the shanks of the staples securely to the tubular rod. Where the curvature of the loop end of each staple occurs, as indicated at 1, they cooperate with the mashed or deflected ends 3 of the shanks of the staple to hold the staple in place.

Extending longitudinally of the tubular rod is a locking rod 5 provided with enlargements 6 at intervals, one at each end, and two intermediate the enlargements at the ends. These enlargements 6 are flattened,

and are provided with L-shaped or bayonet slot 8, to receive a bolt 9, which extends transversely of the tubular rod, in order to hold the locking rod in the tubular rod for limited movement. The enlargement at the other end of the locking rod has attached thereto a ring 10, to which a trip rope 11 is connected. The enlargement having. the ring 10 is formed with a V-shaped slit 12, thereby causing to be formed a yieldable prong or spring catch 13, which is provided with a lug 14:. A spring 15 is connected at 16 to the enlargement having the ring 10, and the other end of the spring is fastened at 17 to the interior wall of the tubular rod; The tubular rod at intervals along its length is provided with slots or openings 18, which are formed transversely, and occur where the L-shaped or bayonet slots are formed in the locking rod 5. The slots 18 are designed primarily for the receptionof the contracted loop ends 19 of the rings or eyes 20. The sling ropes 21 (which are arranged in parallelism for the greater parts of their lengths) are attached to the staples 2 of the tubular rod of the locking means. These sling ropes 21 are connected by transverse pieces 22, which are constructed of any suitable material, such as elm, in order to hold the sling ropes or cables equally spaced and in parallelism, as shown in the drawings. The end portions of the sling ropes 21 at one end of the unloading sling converge toward each other as shown at 23 and are attached to the eyes 2% of the semi-circular ring 25. The unloading sling comprises additional sling ropes or cables 26, which are attached to the eyes or rings 20, and these sling ropes are also spaced in parallelism by the transverse pieces 28, which may be constructed of any suitable material, preferably elm, and have their end portions 29 converging toward each other, the extremities of which are fastened to the eyes 30 of the semicircular ring 31. W hen the contracted loops 19 are inserted in the slots 18 of the tubular rod, the locking rod is allowed to spring back in place under the action of the coil spring 15, thereby permitting the tongues 31 (which adjoin the L-shaped slots 7) to enter the elongated openings 32 of the contracted loops 19, thereby connecting the loops 19 to the tubular rod of the locking means between the two sets of sling ropes or cables. lVhen the locking rod 5 is moved in the direction of the arrow a, by pulling upon the trip rope, which is attached to the ring 10, the lug 14 of the spring catch or resilient tongue will engage the end of the tubular rod, holding the locking rod in an unlocked position, with the tongues 31 out of engagement with the elongated openings 32 of the contracted loops 19.

In the operation of the unloading sling for wagons, it is to be observed that the sling is arranged on the wagon body transversely thereof, the locking means engaging the bottom of the body of the wagon longitudinally thereof, while the sling ropes or cables extend upwardly of the inner faces of the sides of the body, and overhang the sides of the body. The material to be unloaded is arranged in the body of the wagon on the sling, until the body is completely loaded. The other end portions of the sling ropes are brought together, until the eyes 25 and 31 are in registration, and may be connected in any suitable manner if desired. The wagon is then driven to the barn or other place where the material is 'to be unloaded. Any suitable attaching device of a hoisting means (not shown) may then be connected to the eyes 25 and 31, and the hoisting means is then operated, whereby the material may be lifted or hoisted from the body of the wagon. The load of material is then hoisted and swung into position to be released. To release the load of material, the trip rope is pulled, actuating the locking rod 5 against the action of the coil spring 15, thereby disengaging the tongues 31 from the elongated openings 32 of the contracted loops 19. The contracted loops 19 quickly disengage from the elongated slots 18, allowing the load of material to be released from the sling ropes. The sling ropes or cables 26 are then reconnected to the tubular rod, by means of the locking rod and the contracted loops 19, the sling is then disconnected from the hoisting means, after which the sling is then ready to be replaced upon the wagon body to receive another load of material.

The invention having been set forth, what is claimed as new and useful is:

1. The combination with the adjacent ends of sling ropes, of a connecting device between the adjacent ends, said connecting device comprising a tubular rod having staples to which one set of the adjacent ends are permanently attached, said tubular rod having a series of elongated slots, the other adjacent ends of the sling ropes having contracted loops engaging through the slots, a locking rod longitudinally movable through the tubular rod and provided with L-shaped slots having adjoining tongues to enter the openings of the contracted loops of the latter adjacent ends of the sling ropes, spring means for the locking rod, and means for manually actuating the locking rod against the action of the spring means, and a spring latching means carried by the lock ing rod provided with means to engage the end of the tubular rod, to hold the locking rod in an inoperative position.

2. The combination with the adjacent ends of sling ropes, of a tubular rod, a plurality of staples having spaced shanks eX- tending transversely of the tubular rod and being permanently fixed thereto, and to which one set of adjacent ends are attached, contracted loops connected to the other set of adjacent ends, said tubular rod having a plurality of slots to receive said contracted loops, a locking rod extending, movably through the tubular rod and guided between the spaced shanks of the staples, and provided with tongues at intervals to engage the contracted loops, spring means for the locking rod, and means for actuating the locking rod against the action of the spring means, means for limiting the locking rod in its movement. and a spring latching means carried by the locking rod to engage one end of the tubular rod to hold the locking rod in an inoperative position, with the tongues detached from the contracted loops. I

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
