v CABLE HOOK.

Application filed November 13, w26. Serial No. 148,161.

This invention relates to cable hooks and, more especially, to a type ot cable hook suitable for connecting a cable to the beam hanger oit` a. pumping apparatus, though it is to be understood that the invention is not limited to this use. This invention is a division ot my copending application i'or patont, iiled April 13, 1925, Serial No. 22,768.

More spec-itically, the invention relates to a` cable hook constructed ot opposed members positioned so as to permit ot' a cable being placed trom one side on one et the members and from the opposite side on the other member.

Other objects and advantages may appear in the subjoined detailed description.

The accompanying drawings illustrate invention.

Figure 1 is a broken side elevation or' a pumping apparatus having as a part thereoit a cable hook embodying the invention. T he walking beam is shown partly in section.

Figure 2 is an enlarged edge view ot' the cable hook, fragments ot the means tor snspending the cable hook also being shown.

Figure 3 is an elevation ot Fig. l trom the lett thereof.

Figure l is an elevation ol the cable hook on a smaller scale than shown in Fig. 3, with the hook members in open position to permit of removal or replacement ot the cable.

Figure 5 is a perspective view of one oi the hook members.

Referring irst to the apparatus shown complete in Fig. 1, there is an operating member 6 which, in this instance, is in the form ot a nalking beam. ri`he member 6 is pivoted at to a Samson post 8. finspended from one end ot the member G is a beam hanger, indicated in general by the character 9. This beam hanger may be el any suitable construction and, in this instance, is .of a type that eil'ects rotation ol the polish rod. a fragment ot which is indicated 10. It is to be understood that the beam hanger may be ot the nonrotating type it desired, since the type ot' beam hanger has no particular bearing upon the present invention. The beam hanger shown is the subject oi' my copending application tor patent filed April 13, 1925, Serial No. 22,768.

My invention is suspended trom the. beam hanger 9 and is indicated in general by the character 11, and engaged by the cable hook is a cable 12 which connects With a suitable i. tu@

polish rod grip 13 in which the polish rod 1G is clamped.

The cable hook 11 is constructed as iollows: To the beam hanger E) is connected a pivot pin let and mounted to swing on this pin is a pair or' hook-shaped members lo, the open sides ot the hooks being turned toward ay plane intersecting both hooks when said hooks are closed together. as in Figs. l., il and 3 and said plane being normal to the axis ot the pivot pin. The members 15 have their shanks or upper portions 1G in overlapping relation sizlewise. The lower, grooved portions 17 ot the members 15 arey in overlapping' relation edgewisc. The cable 12, when engaged with kthe hook members and connected with a load, prevents swinging of the hook members away from one another. Then the cable is relieved ot its load. the hook members may be swung awajv troni each other, as in F ig. i, thus spacing their grooved portions suliiciently to admitetl the entrance or exit of the bight oi' the cable.

lfilhen the hook members 15 are closed, as

in Figs 2 and the cable 12 rests in both hook members so that each hook member prevent-s removal ot the cable trom the other member. rl`he reason for this is that the hook menibers are opposed or complementary to each other with the backs ot' the hook members on opposite sides ot' the cable.

From the foregoing, it will be readily understood that the invention broadly comprises opposed hook-shaped members, provided with cable grooves on their adjacent tacos, and the backs ot' the hooks being on opposite sides of the cable. It is not absolutely necessary that the hook members be in pivotal relation, but the pivotal construction facilitates entrance and exit ot the lable to the grooves of the hook members.

it desired, one ot the hook members may be provided with a stud 18 adapted to engage in a socket 19 in the other hook memj hook members are in closed position, the stud and socket being on th-e adjacent edges ot the hook members. The stud and socket will resist any tendency to thrusting of the hook members away from one another in directions at right angles to a plane intersecting both hook members.

it may be of advantage in some instances to provide a means tor preventing any tendency to jumping upwardly of the cables in the hook members, and tor this reason I have ber when the Slion'n eaieli liooli member rnforided on ils onler edge wit-b :i parir olf eers Q0, tbe ears of eeeb paiir being on opposilte sides el lille "able Passing' through eneb peil' of eers is :i eoller pin-21, und illus. militer tbe Cable has been placed .in tbe hook memberI :ind l'lie eol'l'er pins lmre been pleieed in position, l'lie alble will lie between, Jrbe oppoeed book .membern 'l5 and also between Clie eoi'iter pins.
