SPECIFICATION forming part of Letters Patent No. 701,654, dated June 3, 1902. Application filed November 2'7, 1901. Serial No. 83,847. (No model.)
'forlifting objects out of wells, but may be usedfor any purpose where it is required to lift objects out of holes' or out of the water.
Referring to the accompanying drawings, in which the samev parts are designated by similar letters of reference throughout the several views, Figure 1 represents a side elevation of my improved grapple, the parts being shown'in their set position ready for lowering into a well. Fig. 2 represents a vertical section of the same, taken on the line 2 2 of Fig. 1. Fig. 3 represents a perspective view of the setting and releasing device. Fig. 4 represents a horizontal section of the de- Vice, on an enlarged scale, taken on the line 4 4 of Fig. 1. Fig. 5 representsa perspective view of one of the grappling-hooks. Fig. 6 represents a perspective View of a series of grappling-hooks attached to a cross-bar, which device may be used in place of the hook shown in Fig. 5. i
A and A designate a pair of shanks, each pivoted about midway of its length in a pair of plates B and B, as at a and a, respectively. The upper ends of these shanks are straight, and the lower ends' are curved away from each other just below the plates B and B, and, then curved to bringtheir lower ends approximately parallel, as shown in Fig. 1.
Between the upper ends of the shanks A and A and just above the plates B and B is secured a V-shaped spring 0, which tends to press the upper ends of the shanks apart,and consequently bring the lower ends together.
Pivoted at a point a. on the shank A is a cross-bar D, formed of two pieces (1 and d. The piece dis provided with threaded sockets d to receive a screw d which projects from the piece at. By this construction the length of the bar D may be varied by turning the screw 1 The free end of the bar D is beveled, as at d, leaving a small square end (1 and the shank A is provided witha shoulder A against which the end d of the bar D is adapted to engage, the beveled part (1 resting against an inclined portion a. of the shoulder. The upper part of the shoulder is inclined, as at a to allow the end of the bar D to slide 0E easily when disengaged. Hung from the middle portion of the bar D is the tripping-arm or the trigger E, which is jointed, as at e, to allow it to swing out of the way of the shank A when the said bar is raised above the shoulder A The upper part ,of the shanks A and A are wider than the lower part and are slotted, as at a, to receive a triangular frame F, the base f of which rests horizontally in the bottom of the slot a and the apex extends slightly above the shanks and isfprovided with an eye f situated above the center 'of the device. The guide-rollers a ando. are journaled in each of the slots a the inclined sides f of the triangular frame F passing between the two rollers of each pair, as shown in Fig. 1. When the triangular frame F is raised,the tendency of the two outer rollers a will be to roll down the inclined sides f and thus open the upper ends of the shanks A and A, closing the lower ends thereof. When the triangular frame is lowered, the inside edges of the sides f? of the triangular frame will press against the rollers (1 and thus close the upper ends ofthe shanks A and A, opening the lower ends thereof. The rope or cable G is attached to the eye f so that in lifting the device the tendency will always be to close the lower ends of the shanks A and'A.
A hook H, like that shown in Fig. 5, or a series of hooks H, like that shown in Fig. 6, is secured to the lower ends of the shanks A and A by set-screws h, the said hooks being pointedat their" 'en'ds, as at h,"and having pointed hooks 7L When, the device is to be lowered into' a well, the lower ends of the shanks having the hooks attached are opened and set in that position by the bar D being placed in engagement with the shoulder A as shown in Fig. 1, the tripping-arm E hanging down between the hooks. The. trippingarm E is provided with a cross-piece c, having a series of pins e pointing downwardly therefrom, and when the hooks H pass down on the sides of an object the tripping-arm will strike the said object and the bar D will be pushed upwardly, thus releasing the shanks A and A, which by the pressure of the spring 0 will immediately close upon the object. When the device is raised, the pull upon the rope G, which is attached to the triangular frame F, will tend to force the upper ends of the shanks apart and close the lower ends tighter, so that the harder the pull upon the rope the tighter the hooks will grip the object to be raised.
A grooved pulley I is mounted in a suitable bracket 1 on the plate B, and an eye F is secured to the base f of the triangular frame F. One end of a rope K is secured to the eye F, and the said rope is then passed downward and around the pulley I and up through the eye F and alongside of the rope G. By pulling upon the upper end of this rope K the triangular frame will be pulled downwardly, thus closing the upper ends of the shanks and opening the hooks. By this means an object which it is impossible or undesirable to lift may be released.
When it is desired to use the device in deep water, a bar M is passed through the plates B and B and one of the shanks A or A in place of the pivot-pin aor a. This bar may be secured in place by a key m, and weights M are secured on the ends of the bar M by set-screws 121..
Although I have described my invention as especially designed for lifting objects out of wells, deep holes, and water, it is obvious that the invention may be used to advantage for other purposes-such as, for instance, the hoisting or lowering of goods to and from the upper stories of warehouses or loading or unloading timber or other objects on cars or the holds of vessels and like purposes. It will also be understood thatI do not wish to limit myself to the precise details of construction as herein described, as many slight modifications might be made in the device without departing from the spirit of the invention.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
1. In a grappling-hook, the combination with the spring-operated pivoted hooks, of a tripping-bar for holding said hooks open, and a trigger suspended from said tripping-bar for tripping the same.
