WIRE SUPPORT Original Filed May 9, 1928 Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE Application May 9, 1928, Serial No. 276,370

Renewed March 5, 1932 13 Claims.

My invention relates to wire supports or fixtures for attaching electric wires to buildings and poles and particularly to devices adapted for parallel drop wire as used with telephone installations.

An object of the invention resides in constructing the support so that the service wire may be attached to the same without the necessity of twisting or splicing.

Another object of the invention resides in providing a device whereby the service wire may be drawn taut about the support and when attached to the same will remain in detachable position through the tension of the service wire.

Another object of the invention resides in constructing the support with a pair of spaced body members constructed with encircling grooves and in forming the wire with a tie having a pair of loops adapted to encircle said body members and lie within said grooves.

A still further object resides in forming the two loops with coextensive reaches positioned within said grooves and adapted to be crowded against one another through the tension of the wire to hold the wire attached to the support.

Another object of the invention resides in mounting said body members for movement toward one another to clamp the adjacent reaches of the wire upon tensioning the wire.

A still further object of the invention resides in mounting said body members upon a U-shaped resilient frame adapted to hold the same in proper manner to place friction on the wires disposed within said grooves.

Another object of the invention resides in providing one of said body members with a socket and the other with a lug adapted to cooperate therewith for holding the same in proper relative position.

With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangements of parts and in the details of construction hereinafter described and claimed.

Fig. 5 is a sectional view of the support shown in Fig. 4 with the service wire firmly attached and taken substantially on line 5-5 of said figure.

In the use of the ordinary dead-end insulator or wire support, considerable time is involved in securing the end of the service wire to the same and in splicing the lead in wire thereto. In addition, breaks and corrosion frequently occur and occasionally the wires become shorted, particularly where a duplex wire is used. My invention overcomes these difficulties by providing a simple and eifective device which may be attached to the wire intermediate its ends so that the trailing end of the service wire may be directly brought into the building and used as a lead-in instead of employing a separate wire for the purpose and making a connection therewith to the service wire.

The wire support proper as best shown in Fig.

1, comprises two body members 10 and 11 which are formed with facing planiform sides 12 and 7 13 and with curved sides 14 and 15. These members are so constructed that when the same are assembled with the planiform sides 12 and 13 facing one another they form a heart shaped construction in which the two sides 12 and 13 extend medially thereof. In each of the body members 10 and 11 and along the walls 12 and 13 thereof are formed longitudinal grooves 16 and 17 which are disposed somewhat below the center thereof. These grooves are adapted to 35 communicate with peripheral grooves 18 and 19 on the curved walls 14 and 15 of said body members which communicate with the grooves 16 and 17 at the shouldered ends 20 and 21 of said body members and which spiral upwardly so as to clear said grooves at the tips 22 and 23 of said body members. These grooves are adapted to receive the wire in a manner to be presently described and serve to hold the same securely attached to the insulator.

The two body members 10 and 11 are supported upon a U-shaped frame 24 formed of wire with two substantially parallel arms 25 and 26, connected together through a looped por tion. The material from which the frame 24 is constructed is preferably a metal having suincient resiliency to cause said arms to return to normal position when sprung outwardly a limited amount. These arms 25 and 26 are constructed with upturned ends 27 and 28 which are threaded as indicated at 29 to receive nuts 30. Each of the body members 10 and 11 is constructed with a central bore 31 adapted to receive the two upturned ends 27 and 28 of the frame 24 and are further constructed with short grooves 32 along the bottom of the same which communicate with the bores 31 and are adapted to receive portions of the arms 25 and 26. By screwing the nuts 30 tight upon the body members l0 and 11, the same may be rigidly clamped upon the arms 25 and 26 and held from rotational or other movement relative thereto. The frame 24 is preferably constructed of spring material and tends to urge the body members 10 and 11 toward one another. The loop at the end of the frame 24 is preferably bent up to bring the same in alignment with the grooves 16 and 17 so as to give a straight pull on the line wire.

For preventing relative lateral movement of the two body members 10 and 11 in the plane of the sides 12 and 13 the body member 11 is constructed at a point below the groove 17 with a lug 33 protruding outwardly therefrom, which serves as a key. This lug is adapted to fit into a corresponding socket 24 formed in the body member 10 at substantially the same relative position. This structure serves to hold the body members 10 and 11 from lateral movement but at the same time permits the two faces 12 and 13 to be moved toward or from one another to permit of the insertion'of the wire therebetween and into the grooves 16 and 17 as will be presently explained.

For the purpose of attaching the support to a building pole or other desired structure, a screw eye such as indicated at 35 in Fig. 4 or any other suitable or equivalent device may be employed.

In using the invention the frame 24 is hooked upon such screw eye the same engaging the looped end thereof. The service wire which I have designated at 36 in said figure is then threaded through the groove 16 and wrapped about the shoulder 20 lying partly in the groove 18 of body member 10. Upon drawing the free end 311 of the wire away from the body member 11 the same is caused to slide around the shoulder 20 and to draw the suspended end of the service wire 36 taut. By pressing against a portion of the end 311 immediately past the shoulder 20 the wire remains temporarily in place. In further attaching the wire to the wire support the free end 311 is twisted into a loop 37 in the form of a half hitch which is looped about the body member 11 with the outgoing portion 38 of the wire lowermost. The outgoing portion 38 of the wire is next forced into the space 39 between the walls 12 and 13 of the body members 10 and Y11 which is made possible by arranging the upturned portions 27 and 28 of the support 24 in slightly diverging relation and by champhering the corners 40 of said body members at the upper portion of the walls 12 and 13 thereof. As soon as the outgoing portion 38 of wire 36 becomes seated within the groove 17 adjacent the incoming portion 36, the loop 37 may be adjusted to fit within the groove 19. The service wire is now properly attached to the insulator and by drawing the outgoing end 38 taut all the slack in the wire will be taken up. Due to the resiliency of the frame 24 the portions of the wire within the grooves 16 and 17 are always held in contact so as to prevent sliding thereof relative to one another and to the insulator. Placing tension upon the wire 36 has a tendency to force the two body members 18 and 11 of the insulator together causing further friction upon said wires and absolutely preventing the slippage or unintentional removal of the wires from the insulator. After the wire has been so attached the free end of the same may then be bent down and brought into the building in the customary manner, thereby entirely eliminating the usual procedure of tying and splicing the service wire to the lead in wire.

Although I have shown my invention as particularly adapted for use in conjunction with porcelain, glass or similar insulating materials, yet. it can be readily comprehended that any of the moulded compositions now available for insulating purposes may be employed and directly cast upon the ends of the supports, thereby eliminating the fastening means shown in the drawing.

The body members 10 and 11 may be also constructed of metal or any other suitable material and may be made integral with the frame 24 or separate therefrom.

My invention is advantageous in that the same can be constructed at a nominal cost from materials such as are now readily available. The entire strain upon the support is taken up in compression through an extended portion of the body members so that breakage due to the tension of the wire is completely eliminated where fragile materials are used in the construction thereof. The tension of the wire serves to hold the portions of the wire in proper relation within the longitudinal groove and serves to retain the free portion of the wire in position so that the same may be conveniently brought out from the wire support in any desired direction and led into a building without danger of loosening or becoming detached from the support proper. Upon sagging of the service wire or upon breakage of the support, the attached end of said service wire may be readily detached from the support and the service wire drawn taut and reattached, or a new support installed without the necessity of disconnecting the lead in from the apparatus to which it is connected. An exceedingly short time is required to attach the wire and considerable economy in both time and materials result in the use of my invention.
