1 Claim.
This invention relates to supporting brackets for telephone wires, feed wires and other electric conductors, and has for its object to provide a comparatively simple and inexpensive device 5 of this character by means of which electric conductors may be securely supported on the insulators of telephone poles and other supports.
A further object of the invention is to provide a supporting bracket which may be conveniently 10 carried by a line man and quickly attached to or removed from an insulator without the employment of the usual tie wires, the construction of the device being such as to permit the opposite ends thereof to yield or sway with the electric conductor during wind-storms or when the conductor is subjected to the weight of sleet or snow and thus assist in preventing bending or breakage of said conductor at its point of entrance into the bracket.
" A further object is to provide a supporting bracket comprising coacrting sections each provided with an opening and having a lateral slot spaced therefrom and opening through one edge thereof for the reception of the adjacent legs of a clamping yoke by means of which the bracket is secured to an insulator and the sections held in gripping engagement wth a conductor wire disposed between jaws of the two sections.
A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efiiciency.
In the accompanying drawing forming a part of this specification and in which similar numerals of reference indicate corresponding parts in all the figures of the drawing:
Figure 1 is a perspective View of a supporting bracket embodying the present invention showing the same in position on the cross arm of a pole,
Figure 2 is a longitudinal sectional view showing the sections comprising the bracket clamped in engagement with an electric conductor,
Figure 3 is a front elevation partly in section, the view being taken along the line 3-3 of Figure 2, Figure 4 is a detail transverse section taken on the line 4-4 of Figure 2, and
Figure 5 is a perspective view of the mating sections comprising the bracket detached and r showing the clamping yoke in position to engage said sections.
The improved bracket forming the subjectmatter of the present invention may be used for supporting any kind of electric conductors, and
by way of illustration is shown in position on the insulator 5 of a cross arm 6 and supporting a feed wire 1. The device comprises mating sections 8 and 9 having longitudinally disposed registering grooves 10 formed therein for the reception of the feed wire, as shown. The sections 8 and 9 are preferably constructed of metal 5 possessing sufficient resiliency to permit the 0pposite ends of the sections when united to yield or sway with the conductor 1 during violent wind-storms or when the conductor is subjected to the weight of ice or snow in inclement weather 10 and thereby prevent the conductor from bending or breaking at its point of entrance into the bracket. The groove I0 is preferably of a diameter greater than the diameter of the conductor 1 and the walls of the groove at the opposite ends 1 of the sections are tapered or flared outwardly at H to allow slight lateral play of the conductor within the groove. The walls of the groove [0 at the intermediate portion of each of the sections 8 and 9 are preferably angular in cross section, as indicated at 12, so as to firmly grip the conductor when the sections are assembled and clamped together, there being a rubber casing or bushing 13 fitting over the conductor 1 for the entire length of the bracket, as best shown in Figure 2 of the drawing. The section 9 is provided with a lateral extension or boss l4 having a concave seat l5 which fits within the groove of the adjacent insulator 5 and to which it is securely fastened by a U-shaped yoke or clamping member l6 formed of resilient material. Each bracket section is provided with an opening l1 adapted to receive the adjacent leg of the clamping yoke 16, there being a slot l8 formed in each bracket section in spaced relation to the opening I! and adapted to receive the other leg of the clamping yoke. Each slot l8 opens through one side of the section so as to permit either section to be swung laterally to the inoperative position. The ends of the clamping member iii are threaded for the reception of nuts I9 by tightening which the bracket sections may be clamped in engagement with the electric conductor and the boss M in engagement with the adjacent in- 4 sulator. 5 Inasmuch as one leg of the clamping member I6 extends through the opening I! in one bracket section and the other leg of the yoke through the opening I! in the other section, said legs form pivots for the sections irrespective of which section is swung laterally to open or inoperative position. The construction of the device is such that a number of the supporting brackets may be suspended from the belt of a lineman and conveniently carried from place to place for instant use when necessary.
It will, of course; be understood that the brackets may be made in different sizes and shapes and constructed of any suitable material without departing from the spirit of the invention.
Having thus described the invention, What is claimed as new is:
A supporting bracket for a conductor wire comprising coacting elongated sections normally disposed in substantially parallel side by side relation to each other, the confronting inner side faces of said sections being formed with opposed longitudinally extending wire-receiving grooves open at their ends and spaced from upper and lower edges of the inner faces of the sections, said sections having their intermediate portions thickened to form depending extensions, the said extensions being each formed with a slot leading from its lower edge and an opening spaced from the slot longitudinally of the section and positioned to register with the slot of the other section, a boss extending laterally from the outer face of one section between the opening of the slot formed therein and having a concaved outer end for receiving a portion of an insulator, and a U-shaped fastener for securing an insulator in the concaved end of said boss having its arms extending along opposite sides of the boss and through the openings and the slots of said sections and provided with securing nuts upon their protruding. ends.
