GRAPPLE FOR EAY-LOADERS.

Specification of Letters Patent.

Patented Nov. 6, 191 '7 Application filed. July 31, 1916. Serial No. 112,295.

To all whom it may concern:

Be it known that I, TAMESABU'RO AnAKI, a citizen of Japan, and a resident of Fromberg, in the county of Carbon and State of Montana, have invented a new and Improved Grapple for Hay-Loaders, of whleh the following is a full, clear, and exact description.

My invention relates to a portable apparatus for loading hay or the like, and is more particularly intended for use in loading material from a stack onto a vehicle.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

F igure 1 is a plan view of my improved grapple, some of the controlling cables and portions of others being omitted;

Fig. 2 is a side elevation of the grapple.

My improved grapple is adapted to be suspended from any overhead boom or other support. The grapple is equipped with a series of grabs, 19, 19 said grabs being alternately shorter and longer so that they may be clustered in compact form. Each grab has a tine, or tines, 20, and the grabs are pivoted as at 21, 21 for radial swinging movement to close and open the grapple when grabbing and depositing a load. The pivots are in brackets, 22, 28, on thegrapple frame 18. The grapple is suspended from a hoisting cable 24 from which branches 25 run to the upper ends of the grabs 19, 19*. In order to swing the grabs outwardly on their pivots for opening the grapple, a cable 26 connects with a ring 27, from which branch cables 28 run over sheaves 29 on the heels 30 of the grabs, the ends of the cables being fast to the frame of the grapple as at 31.

The cable 26 controlling the grabs, 19, 19 runs in practice to any suitable operating means (not shown).

In the use of the grapple, as for example in taking hay or straw from a stack, the grapple is raised to the desired height through the medium of the cable 24 and positioned over the stack. The grapple is then lowered by the operator onto the stack and the cables 24, 26, are so manipulated as to open the grabs and close the same on a load, whereupon the grapple is raised and moved by any suitable carrying means (not shown) over a wagon to be loaded, for example. When the grapple is over the point of deposit of the load, the cable 26 is manipulated to release the grabs and permit the load to drop.

By the described construction, one man stationed adjacent to the hand wheels 42, 62, can control the complete operations of opening and closing the carrier as required, tilting the walking beam and swinging the jib 15. The lever by a proper proportion of its longer and shorter arms, gives the necessary power for raising the walking beam, and the provision of the lever 37 enables the cable 24 to accommodate itself to the rocking movement of the walking beam.

The lever 37 is counter-balanced by a weight 89, (Fig. I), hung on a cable 90 connected with said lever as at 91 and running over a sheave 92 on the post 84.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. In a loader of the class described, a grapple comprising a series of grabs pivoted between their ends to rock in a vertical plane and provided at their lower ends with tines, the respective tines being disposed toward one another, a cable having connections with the several grabs above the pivots thereof, to suspend the grapple and serve to open the grabs, a second cable to close the grabs, and branch cables connected with the second cable and each having running engagement with the grabs below the pivots thereof and made fast to a relatively fixed part of the grapple. V

2. In a loader, a frame, a series of grabs pivotally hung between their ends on said frame, a cable connected with the several grabs above the pivots thereof to close the grabs, a second cable, a ring suspended on the second cable, and flexible elements each connected at one end with the ring, and made fast at their opposite ends to said frame, said flexible elements having running engagement with the grabs below the pivots thereof.
