CONDUCTOR SUPPORT Filed Feb. 6, 1936 10 avoid damage to the conductor.

iatenteci Apr. 2 7, 193'? PATENT OFFICE 2,079,424 ooivnn'c'ron surr oit'r Loid M. Stinchcomb; Jackson, Mich. Application February 6, 1936, Serial No. 62,554} s elaim s. (01. 248-63) This-invention relates to supports forelectrical conductors and particularlyto such fittings for use in stringing electric power lines in ruraldistricts. 1

5 When. stringingan electrical conductor along a country road, for instance, which has a bend, care must be taken to avoid too sharp a bend in the conductor, particularly when aluminum conductors, which are relatively brittle, are used, to

Furthermore When it is necessary to tap an intersecting conductor onto the through one some device must be provided to prevent the pull exerted by the intersecting conductor from being applied direct- 15 ly to the through one.

According to the present invention a single device is provided to perform both functions so that only one connection to the pole is necessary. In general the device, according to the present inventiomfor performingthese functions comprises a separate corner fitting for guiding the through conductor around the. bend, the conductor being supported with a bend of a nondamaging radius and a separate end fitting detachably connected to the first fitting for bearing the pull exerted by'the intersecting conductor.

An object of the invention is to. provide detachable end and corner fittings asdescribed above.

Another object is to provide the corner fitting so that a conductor may pass through it at any angle from 180 to 90 degrees or less, as desired.

A further object of the invention is to design both the corner and the end fittings so that they 35 may be separately used.

These and other objects will be apparent from the following specification when taken with the accompanying drawing in which:

Fig. 1 is a side view of the assembled end and corner fittings having a portion of the corner fitting taken away,

Fig. 2 is an edge of the corner fitting,

Fig. 3 is an edge view of the end fitting,

Fig. 4 is a side view of the invention showing a 45 connected through conductor and intersecting conductor supported by the assembled corner and end fittings, and

Fig. 5 is an elevation of a modification wherein the necessity of a separate corner fitting and 60 end fitting is dispensed with.

Referring particularly to the drawing the corner fitting I is provided with supporting ears 2 having opposed openings 3 and an opposed connecting eye 4. Intermediate the ears 2 and 55 the eye 4 is disposed a curved wire supporting member 5 somewhat in the shape of a channel having through the sides thereof a plurality of transverse slots 6 defining outwardly extending conductor retaining projections 1, the slots 6 being for the purpose of receiving wrapping for binding a supported wire in the member 5. The conductor receiving member 5 is preferably arouate in shape and in length equal to a quarter of a circle. It should be observed that the corner fitting I may support a wire going straight through or one having any bend up to 90 degrees. Each end of the wire supporting member 5 is belled out to provide a slightly enlarged entrance to prevent chafing.

Supported from the connecting eye 4 is an end fitting 8 generally annular in form and having a peripheral channel 9. Extending in one direction from opposed sides of the peripheral channel 9' are ears l0 being provided with opposed pin receiving openings II. The end fitting B is connected .to the corner fitting I by moving the ears l0 into overlapping relation with the connecting eye 4, aligning the pin receiving openings II with the eye 4 and inserting therethrough a pin l2 which may be retained against removal by a cotter pin I3, for instance.

In operation. as disclosed in Fig. 4 the straight through wire or conductor [5 is disposed about the corner fitting I" at an angle corresponding to the bend in'the road along which the wire or conductor is being strung and is securely bound with a wrapping Hi. It will be obvious that the curvature of the corner fitting determines the curvature of the conductor l5. Accordingly the curvature of the corner fitting should be sufficiently great to prevent damage to the conductor for which it is to be used. The intersecting conductor I! is looped about the end fitting 8, bound to itself by a wrapping I8 and the free end secured in any suitable manner to the through conductor [5. Thus the pull exerted by the intersecting conductor I1 is transferred through the end fitting 8 to the ears 2. If desired either the end fitting 8 or the corner fitting I may be separately used.

In Fig. 5 a modification is disclosed wherein the end fitting 8 may be dispensed with without dispensing with its function. In this modification only a corner fitting 20 is necessary. The corner fitting 20 is provided with supporting ears 2| corresponding to the supporting ears 2 and a through support 22 corresponding to the through conductor support 5 of Fig. 1. In order to provide a support for the intersecting conductor the corner fitting 20 includes extensions 23 from the through conductor support 22. The extensions 23 preferably are arcuate in form having the same radius and center of curvature as the through conductor support 22 and are of sumcient length to prevent any sharp bends in the intersecting conductor when it is looped around the corner fitting 20 and bound against itself in a manner illustrated in Fig. 4. The width of the support disclosed in Fig. 5 may be the same as that disclosed in the embodiment of Fig. 1 but preferably it is sufliciently wide to receive the through conductor and intersecting conductor side by side.

While the invention has been described as particularly adapted for carrying conductors in rural use it is not necessarily so limited. and it is intended that the invention be used wherever feasible and for whatever purpose desired.

While the foregoing description describes a specific embodiment it is illustrative of the invention and, therefore, I do not wish to be limited except by the scope of the following claims.

I claim:
