DEVICE FOR HOISTING GRAIN.

SPECIFICATION forming part of Letters Patent No. 641,961, dated January 23, 1900.

Application filed April 5, 1899. Serial No, 711,803. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID D. HILL, of L0- gan, in the county of Phillips and State of Kansas, have invented a new and Improved Device for Hoisting Grain, of which the following is a full, clear, and exact description.

The object of this invention is to provide a simple, durable, and portable device especially adapted for hoisting headed grain to a wagon or to a stack and to so construct the device that the grain will not be injured in handling and so that the grain may be readily carried to and dumped at any side of a stack.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

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

Figure 1 is a perspective view of the improved device, and Fig. 2 is a partial side elevation and partial vertical section of one side of the hoisting-frame.

The body of the device consists of a frame D, adapted to be supported by a hoist-rope 21, which may be connected with any source of power. This frame isshown as rectangular, the rear bar 24 and side bars 25 being securely attached, while the front bar 26 of the frame is connected with the side bars by hinges 27, the hinges being at the under faces of both the front and the side bars, so that it is possible for the front bar to drop downward below the plane of the under face of the frame, as shown in dotted lines in Fig. 2. The frame is connected with the hoist-rope 21, usually through the medium of four auxiliary ropes or chains 23, all of these auxiliary ropes or chains being attached to the main hoist-rope, and two of the auxiliary ropes or chains 23 are attached to the upper face of the rear bar of the frame, while the other two are secured to the under face of the front or drop bar of the frame. Thus while the frame is sustaining a load the tendency of the auxiliary ropes or chains connected with the drop-bar is to force the bar downward; but the front bar is held in position for engagement with the face of the side bars or in normal position by means of a latch 29, which is secured, preferably, to the upper face of one side bar and extends across the top of the front or drop bar 26 and downward at its forward surface.

Outwardly-facing hooks 28 are secured to the front bar 24 of the hoisting-frame and the drop-bar 26, the hooks extending below the under faces of these bars. Thelatch 29 is raised through the medium of the crank-arm 30 of a lever 31, said crank-arm 30 being held to turn in a recess 32, made in the side bar 25, immediately under the latch 29, as shown in Fig. 2. Thus by raising the crank-arms the latch is raised, and when the crank-arm is horizontal the latch occupies a like position. The lever 31 is operated through the medium of a rope 33, that may extend to the ground.

A canvas 34 is employed in connection with the hoisting-frame D, and this canvas is provided with a series of rings 35 at the front and at the rear edge, the rings being so placed that they may receive the hooks 28 on the hoisting-frame, as shown in Fig. 1.

In operation the canvas is placed upon the hay rack or carriage of a wagon and the grain is loaded onto the canvas. The loaded wagon is then driven beneath the frame D and said frame is lowered until the rings 35 on the canvas can be passed over the hooks 28 on said hoisting-frame and the latch 29 is made to engage with the front or drop bar 26 of the hoisting-frame D. By means of the hoistrope 21 the canvas and the load carried thereby are drawn upward and the canvas and load of grain are taken over a stack or over a point where the stack is to be built. When the grain has been properly distributed, by drawing rearward upon the rope 33 the crankarm of the lever 31 is carried upward and the latch 29 is released from the front bar 26 of the hoisting-frame D, and said front bar 26 will drop to the position shown in dotted lines in Fig. 2 and the rings carried by its hooks will become disengaged, permitting the load of grain to escape from the canvas.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A hoisting-frame for grain, consisting of side bars, and a cross-bar secured to the side bars at one of their ends, a drop-bar hinged to the opposite ends of the side bars, a looking device for the drop-bar and a trip for the locking device, substantially as described.

2. A hoisting-frame for grain, consisting of two side bars, a cross-bar fastened to the side bars at one of their ends, a drop-bar having a hinged connection with the side bars, a latch for the drop-bar carried by a side bar, a releasing-lever for the latch, and retaining devices for a grain-receptacle carried by the cross-bar and drop-bar, substantially as described.
