3 Claims (01. 145-50)...

The invention relates generally to tools-used by linemen, andmore .particularlytoqa tool to assist a telephone lin'emanin installing 'a ,hook to support an insulator.

h eral. ob ect. of t i ren niisjto' 'p o.-. e. a novel i001 f cil ti he' sta la'tion f. insulator hooks, which is adapted .to be used with other tools, ordinarilycarried by a telephone, lineman, and which permits themto installlthe hooks quickly and with a minimum o-f efiprh.

Another object is to provide a novel tool ofthe foregoing character, which maybe easily .placed, on a hook and removed therefrom, andgwhich engages the hook without marring the t ieads: thereon.

A further object; is to .providea noveltool of; the foregoing character which so .-interfits .withthe hook that, whenend pressure isplaced m1. the tool to force the hook inwandly,the-$0014 held in axial .alignment with the hook- Other i ts {and a van a e w l-b come. ap.-, parent from the following descriptiqnt takonzrini connection with t e acc mpanyin d awi s; 3. which:

In installing a telephone in a building such as a house, the wire which extends from a nearby pole is secured to an insulator usually mounted on the side of the house. The insulator is so secured to the structure of the house that it will carry the physical stress of supporting the wire. Thus, in Fig. 1, I have shown a portion of a house at It) with an insulator H mounted thereon. The insulator is usually made of ceramic material or the like and preferably has a spoollike form. To support the insulator, a hook, indicated generally at [2, is provided.

The hook I2 is of standard form and comprises a shank l3 provided at its end with woodscrew threads l4 adapted to be screwed into the structure of the building. Intermediate the ends 2 of thehook an offset-portion'lfi. is vprovided and the outersend. ofthezxhook indicated-at 11-6, is ntiataan angle o-the shank to extend upwardly andn'outwardiyiifrom the-building structure: to receive the insulator i l. The-endportionlfi is threadedas 813 1112 to receive a nut 1'82 adapted to hold theinsulator :H ;on:.ithe hook. It vis commonpraotice among; telephonelinemen to' install such a ;'hook by:- firstydriving; a starting:- hole in: the building structure into which the 1 threaded: end. M. of the thookwis inserted." Such-starting hole is frequentlyformed .merely by: driving. a spike: a short distance into'.thebuilding structure and then removing it.

In screwing the hook into the buildingafter inserting it into the starting hole; considerable torque is required-and the lineman has difficulty in applying such torque i f he merelyattemptsto--do so by means-ofpliersor an ordinary-wrench. However, a telephone lineman usually carries, as part of his kit', a carpenters brace, so that'if a tool-adapted--tobe-utilized with such a brace were-provided; the insertion of the hook would be greatlyffacilitated; i The-present invention-provides-such, a tool:

shown inf'thezdrawings, the preferred embodiment of thetool comprises-a shank 20 provided atone end with-a taperingsquared portion 2l"0f usual form to .fit. into 'a carpenters brace; 0111 the other endof the shank .Zllithere is provided means for gripping-the hook and holding it inaccurate axial; alignmentwith the brace. To.th'is,.en'd, such meanscomprises a pair of jaws 2'2' spaced apart sufficiently to embrace the hook and preferably of sufficient width and length, as indicated in Fig. 4, to completely. embrace the offset portion l5 of the hook. Extending generally laterally from the jaws and in proper angular relation is a tubular extension 23 adapted to receive the portion l6 of the hook. The tubular extension 23 is of substantial length and extends for a substantial distance laterally from the jaws so that adequate torque may be applied to the hook without chance of damaging the threads I! thereon. The bore of the tubular extension 23 extends through the space between the jaws 22 so that the tool may be placed on the hook merely by sliding it laterally over the end portion is thereof.

As heretofore mentioned, some end pressure must be applied to the hook by the tool when inserting it into the starting hole in the building structure. Such end pressure is necessary in order to cause the threads M to bite into the 3 wood of the building. The particular angular relationship of the portion [6 of the hook to the shank 12 would tend to cause the tool to shift laterally on the hook, when end pressure is applied, and thus would tend to cause the tool to become misaligned with the hook. To prevent such action from occurring, I so form the tubular extension 23 as to engage the offset portion l of the hook when the shank 2B of the tool and the shank 12 of the hook are aligned. Thus, the tubular extension 23 has a portion 24 extending between the jaws 22 to engage the bend of the oifset portion l5 when the shank 20 of the tool and the shank l2 of the hook are in axial alignment. Consequently, when end pressure is applied to the tool, it will tend to shift laterally,

because of the angular position of the tubular extension 23, until the portion 24 engages the offset portion I5, and at such time proper align-' ment of the tool and hook are provided.

From the foregoing description, it will be apparent that I have provided a novel tool to facilitate the work by a telephone lineman of installing an insulator hook. With a tool of the character herein disclosed, such hooks may be quickly installed with a minimum of' effort. The tool is easily placed on and removed from the hook and engages it in such a manner that the threads thereon wil1 not become marred and so that torque may readily be applied to the hook to screw it into the building structure. The tool interfits with the hook in such a way that, when end pressure is applied to the tool, it shifts to an aligned position with the hook.

I claim:

1. A tool for inserting a. hook formed with a shank portion, a stem portion extending at an obtuse angle to said shank portion and a bent offset portion between said shank and stem portions, the bend of said offset portion lying in the plane passing through the shank and stem portions, said tool comprising a, shank, a pair of parallel spaced jaws extending from the end of the shank, the spacing of said jaws being suificient to embrace the offset portion of said hook, and a tubular extension projecting generally laterally from the jaws and at substantially the same angle to the jaws as that between the shank and stem portions of the hook and adapted to receive the stem of the hook, said tubular extension having a portion projecting between the jaws to engage in the bend of the ofiset portion of the hook, whereby the shank of the hook and the shank of the tool become axially aligned upon application of end pressure to the shank of the tool and toward the hook.

2. A tool for inserting a hook having a. shank portion, a stem portion extending at an obtuse angle to said shank portion and a bent portion connecting said shank and stem portions, said bent portion lying in the plane of said shank and stem portions, comprising a shank, a pair of spaced jaws extending from the end of the shank and adapted to embrace the bent portion of the hook, and a tubular extension projecting laterally from the jaws at substantially the same angle to the jaws as that between the shank and stem portions of the hook, the space between the jaws adjacent the tubular extension forming a continuation of the bore of said extension whereby the tool may be readily placed on the hook by sliding it laterally over the stem of the hook, the angular relation of the tubular extension to the jaws causing the bent portion of the hook to shift into engagement with the inner end of the tubular portion when end pressure toward the hook is applied to the shank of the tool.

3. A tool for inserting a hook comprising a threaded shank portion, a stem portion extending at an obtuse angle to said shank portion, and a bent portion lying in the plane defined by said shank and stem portions, said toolcomprising a shank, a pair of spaced jaws extending from one end of the shank of the tool and adapted to embrace said bent portion of the hook, and a tubular extension projecting laterally at said end of the shank of the tool at the same angle to the jaws as that between the shank and stem portions of the hook to receive the stem portion of the hook, said tubular extension having a portion extending between the jaws to engage in said bent portion and thereby prevent the tool from shifting laterally of the hook when end pressure toward the hook is applied to the shank of the tool, said end pressure forcing the shank portion of the hook into centered relation with said shank of the tool by virtue of the angular relation between said extension and the shank of the tool.
