J. H. BRINTON, OF THORNBURY,PENNSYLVANIA.

Letters Patent No 93,590, dated August 10, 1869; antcdaterl August 6, 1869.

IMPROVED GRAPPLE.

The Schedule referred to in these Letters Patent and makin part of the same.

To all whom it may concern:

' Be it known that-I, J. H. Bnmron, of Thornbury,

Chester county, Pennsylvania, have invented ah Imscribe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which Figure 1 is 'a side view of my improved hay-elevator, and

Figure 2 the same, as it appears after the discharge of a load from between its jaws.

Theapparatus consists of two metal bars, A and A, crossed and jointed at a, and so bent at their lower ends as to form curved jaws, between which a mass of hay may be held, while the upper ends or arms of-the said bars. are straight, and nearly parallel with each other when the jaws are closed, as shown in'fig. 1. The apparatus is suspended by a rope, B, which passes through slots at the upper ends of the arms A andA, and beneath pulleys c 0, arranged to turn in the same, one end of the said ropebeing secured to some stationary object, and its opposite end passing over a pulley,:v, and thence-to the point from which the apparatus is to be operated.

The cord F is secured to the jaw A, at the point (1, and passes around a pulley, j; which is attached to the upper end of the bar A, there being at the outer end of the said cord, a metal ring or eye, It, through which the operating-rope passes, but the diameter of which is too contracted to admit of the passage of the ball H.

The mndeofloading-the grapple with hay or othermaterial is apparent, the jaws being opened and forced downward into a mass of hay, and closing and grasping a portion of the mass, when the whole is raised by means of the Operating rope. 7

When the elevator and its load have been raised to r the required point, the ball H of the operating-rope passes beneath the pulleys -c c, and-strikes against the ring'k of the cord F, but cannot pass through the same, and as the ball continues to move toward the pulley as, carrying the ring and end of the cord F with it, thelatter will draw the jaw A, and upper end of the bar A toward each other, until the centre of gravity of the apparatus becoming suddenly shifted, the jaws are completely opened, and the load discharged.- I claim as my invention, and desire to secure by Letters Patent- A cord, F,tconne cted to the jaws A A of a grapple,

and having a ring or eye, k, at its outer end, for the passage of the operating-rope, all substantially as and
