GRAPPLlNG-IRON.

SPECIFICATION forming part of Letters Batent No. 660,219, dated October 23, 1900. Application filed February 13, 1900. Serial No. 5, 069. (No model.)

To aZZ whom it may concern.-

Be it known that I, PEARSON F. McCLIN- TICK, a citizen of the United States, residing at Brookfield, in the county of Linn, State of Missouri, have invented certain new and useful Improvements in Grappling-Irons; 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.

This invention relates to grapples in general, and more particularly to that class employed in grappling and raising objects from the bottoms of wells and from other locations where the operator cannot manipulate the grapple entirely with his hands to engage it.

The object of the invention is to'provide a construction in which there are employed no rigid connections for manipulation of the jaws of the grapple and in which there will be few parts so constructed that the chances for injury and disorder will be reduced to the minimum. p

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is a perspective view showing the portions of the parts when the jaws are open for engagement with a body to be raised. Fig. 2 is a side elevation with the parts in position to close the jaws. I

Referring now to the drawings, the present invention comprises a carrier for the operating-cords, including a metallic strap which is bent upon itself to form a bight 5, and two arms 6 and 7, the free ends of which are curved outwardly in opposite directions and are provided with longitudinal slots 8 and 9, as shown. Fastened to the metallic bight 5 of the metallic strap is a cross-head 10, lying at right angles to the medial line of the arms (3 and 7, and in the extremities of the crosshead are perforations 11 and 12.

In connection with the carrier above described there are employed two jaws 15 and 16, the mutually-adjacent ends of which are connected by means of a hinge l7,and these jaws are so shaped that when they are in their grappling positions, as illustrated, they will outline substantially an oval, the apex flexible connection, the inner end of which is connected wit-h the inner face of the opposite jaw, the ends being secured as shown. These cords 20 are passed upwardly through the slots 8 and 9 and the perforations 11 and 12 in the cross-head 10, above which latter they are connected, as illustrated. It will thus be seen that by drawing upon the cords 20 the jaws will be moved upwardly and into contact with the arms 6 and 7 and that further upward movement will bring the grappling edges of the jaws together by drawing the jaws upwardly between the ends of the arms. The cords 20 are shown as continued through the jaws as a means of attachment thereto and are knotted at each side of the jaws to prevent displacement with respect thereto, after which they are continued upwardly and through the perforation adjacent the extremities of the cross-head, at both sides of which they are knotted to preventdisplacement. The opposite ends of the cords, as shown, are passed through alining perforations in the bight 5 and the cross-head, and the corresponding ends of the cords are joined together and provided with a single rope attached thereto, these ropes being indicated at 25 and 26. It will thus be seen that if the device be suspended by the rope 25 the mutually-connected ends of the jaws will fall downwardly and the jaws will drop away from the arms 6 and 7 and will open. Thegrapple may then be manipulated through the medium of the cord 25 to cause the jaws to take over an object, and bythen allowing the cord 25 to fall slack and drawing in on the cord 26 the carrier will be dropped and the connected ends of the jaws will be brought to lie wedged between the arms 6 and 7, and thereby will secure a tight grip.

Having thus described my invention, what I claim is 1. A grapple comprising hinged jaws having perforations adjacent their mutual connection, and a cord passed through the perforation of each jaw and connected with the opposite jaw between the perforations and the grip edge of the jaw, whereby the jaws may be suspended in a closed position.

2. A grapple comprising jaws having a hinged connection, a guide in each jaw adjacent the hinge,a cord passed through the guide of each jaw and connected with the opposite jaw between the guide and the gripping edge thereof whereby the jaws may be suspended in a closed position and means connected with the jaws for holding them in their open position.

3. A grapple comprisingacarrier including converging members having openings in their outer extremities,a cross-head connected with the carrier, jaws having a hinged connection and adapted to fold andenter between mem bers of the carrier to close them, means for raising the jaws to enter between the converging members of the carrier to close the jaws and means for raising the carrier from the jaws to permit them to open.

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