The" structure of the grip illustrated in Figs. 5 and 6, is particularly adapted for use as a lire escape for Wire or rope climbers, and it includes :L body 20, which is sub stantially lll-shaped in crosssection includn ing sides 2l and 22 and a bight portion 23.
The vsides' 2l and 22 are `provided with alin ing. slots 2d formed in the Sider. 2l. and f which sides are positioned at angles to the longitudinal lines of the body 20. A gripping pin is slidablymounted Within the to vthe bight portion 23, adjacent to its lower end, .y and it hasva stirrup 31 mounted upon its'lower end. In using the structure of grip illustrated inv Figs. -5 and 6`forthe purpose of climbing a wire, a pair o'such devices` isordinarily used, and by. actuating the bars 28 and 26, the grip upon a rope or Wire, such as is yindicated at 33 lmay be changed as desired.' For instance: a personL using the device for climbing a wire, .would place one of his feet in the stirrup 31 of one of the devices, and operate the bars28 and 26 for "securelyclamping the wire 33 between the gripping rods25 and the bight portion of the body 20. After a irm grip upon the Wire has been obtained by one of the Vmembers20, the second member would be loosened and raisedA upwardly upon the wire or rope, after which `it would befastened so as to rmly grip the Wire, and one of thefeet `of the operator vplaced in the stirrup carried thereby. This operation might be continued until the desired height is .reached ontherope or wire. In using this structure as a fire escape, the speed of the descent of a person traveling down the rope or wire Vcould be regulated by adjusting thejgripping action by the grippingrod 25 through the adjustment of the bars or levers 28 and26. Y,
The. modiied form illustrated in Figs. 7 and 8 of the drawings, such asis used for the*V purpose or" grabbing tools such as broken bitsor the like from Wells, includes a body 40 which may be conical-shaped, cylindrical-shaped or square, as desired, Without departing from the spirit of this invention. The body 40 is provided .with a pair of. angularly disposed slots 41 in n Whichisslidably,seated a clamping pin or Y bolt 42. The bolt'or pin 42 hasarms 43 and 44connected to itsopposite end, which bars are in turn pivotally vconnected as is shown at 45 to bars 46. The bars 46 are pivotally connected at 47 to the body 40 and they have flexible members, such as cord or wire 48 secured thereto and extending upwardly therefrom.
A pin 49 extends diametrically through the body 40 upwardly of angularly disposed slots 41 and it has a wire 50 attached thereto, as is shown at 51. When the grab structure is used for the purpose of grabbing pieces of broken bits from the well or the like, the body 40 is lowered into the well, and the cords 48 are slack. When the pieces of bits or tools in the well are engaged by the grip or grab structure, the wires or iiexible members 48 are drawn taut which moves the clamping pin 42 upwardly in the body 40 and causes the pin to securely clamp the piece of the bit between the inner wall of the body 40 and the pin 42. After the piece of bit has been securedly clamped between the pin 42 and the wall of the member 40, the entire structure is withdrawn from `the well through the medium of the wire 50.
In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alteration to which the patentec is entitled provided such alterations are comprehended within the scope of what is claimed. y
Nhat is claimed is Agrip structure as specified comprising aframe of U-shaped form in cross section and embodying a base and side pieces, said side pieces being provided with a pair of alined angularly disposed slots, a clamping pin extending through and slidably mounted Within said slots, operating bars pivotally secured to the outer surfaces lol the side pieces, links `pivotally connecting the operating bars and the ends of the clamping pin, and enlarged heads formed on the ends of said. clamping pin and engaging said links to prevent accidental removal of the same by lateral movement of the clamping p In testimony whereof I aix my signature in presence of two Witnesses.
