HERBERT COTTRELL, OF NEXVARK, NEW JERSEY.
DEVICE FOR ATTACHING TELEGRAPH-WIRES TO POSTS AND INSULATING THEM THEREFROM.
SPECEEICATIQN forming part of Letters Patent No. 297,677, dated April 29, 1884:.
(No model.)
Jib (tit whom it may concern:
Be it known that I, HERBERT CorrnnLL, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Device for Attaching Telegraph-Wi res to their Posts or Supports and Insulating them Therefrom, of which the following is a specification.
The object of my invention is to provide a combined hook, insulator, and tie for attaching telegraph-wires to poles or other supports which will facilitate the rapid construction and repair of telegraph-lines, and which will also, without the use of binding-wire, hold the telegraph-wire positively at each support, so that in case of a break of the wire it will only drop between the supports where the break occurs.
To this end theinvention consists in a novel construction and combination of parts, as will be hereinafter explained, and pointed out in the claims.
- In the drawings, Figures 1 and 2 represent a hook, insulator, and tie constructed according to my invention, Fig. 2 being a View at right angles to that of Fig. 1. Fig. 3 is a longi-' tudinal view of the inner face of one-half of the divided tie or clamp and insulator. Fig. 4 is a transverse section through the line 00 90, Fig. 2.
Similar letters refer to similar parts throughout the several views.
A designates a hook, which may be screwthreaded or otherwise suitably constructed at one end, a, to be attached to a pole or other support, and which has its other end, 6, constructed in the form of a hook, to receive a longitudinally-divided clamp or tie, B B, 0011- taining insulating material C 0, within which the telegraph-wire D is placed and secured.
The divided clamp or tie B B is provided at one end with a head, 0, adapted to receive a wrench, and that part of its exterior which is received within the hook A is of slightly elliptical or cam-like transverse section, as shown in Fig. 4, so that by turning it in the hook by means of a wrench it may be tightened and locked both within the hook and upon the wire. The interior of the hook may be of true circular form, with a throat or opening, 9, considerably less than half of its circle, and the exterior of the clamp or tie B B may be circu lar, to correspond therewith, except that at one portion of its circumference it may be made with a slight fullness or projection, so that when this part so projecting is opposite the throat g of the hook the clamp will fit within the hook loosely, and can be freely inserted or withdrawn from it endwise, but that the clamp on being turned either way will be caused by the projecting part to tighten within the hook and lock the parts firmly together.
The exterior of the divided clamp B B, instead of being made as Just mentioned, may be made of oval form, as shown in Fig. 4, its greater diameter 0 0 very slightly exceeding the diameter of the circular opening of the hook, while its smaller diameter ff corresponds very nearly to that of the hook, so that on the clamp being placed with its greater diameter e e in line with the center of the throat g of the hook it can'be operated to lock-the parts firmly together by turning it in either direction in a similar manner to that already described, as is illustrated in Fig. 1.
The insulating material in the divided clamp G O, with which the two halves or members of the divided clamp islined, may be gutta-percha or vitreous material, the former, when used, being pressed into place while plastic, and the latter being cast into recesses provided for it in the interiors of O O.
The joint in the clamp and insulator may be protected against entry of moisture, and consequent destructionof the insulation of the wire, by being varnished with waterproof varnish, which will run in between the two faces of the insulator and clamp, if applied after the latter is in place, ready to be turned and locked within the hook, or the complete insulation may be secured by a thin strip of rubber, a, laid in the full length and width of the joint, as shown in Figs. 1 and 4. The hook, after being screwed into a pole or other support by means of a pin or lever inserted into its loop to turn it, will first receive the line-wire D through the mouth after which the two halves of the clamp B B are so placed around the wire that the greater diameter 0 0 will be in line with the center of the throat g of the hook A, when they are inserted endwise into the hook, and afterward slightly turned by a wrench applied to the head 0, by which latter operation the clamp is both firmly secured in the hook and the wire is firmly grasped by it, the wire being thus insulated and tied or secured firmly to the pole or support without the use of the binding-wire, which is used commonly to secure the wire to an insulating-hook. WVhen these hooks are used all along a line, the wire is secured to every pole independently of each other, and any single breakage of the wire only causes it to fall between two poles.
I do not wish to be understood as broadly claiming an insulator for telegraph-wires composed of two sections for embracing the wire and adapted to be turned in a socket of an arm on the telegraph-pole to retain the sections in place, as such is not of itself new.
hat I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination oft-hchook constructed to be attached to a telegraph-pole, and the divided clamp B B, lined with insulating material C O, the sections of said clamp being adapted to be placed together with the wire between them, and then slipped laterally through the hook, and afterward turned, the divided clamp being formed elliptical or eam-like in crosssectio'n, whereby when it is inserted in the hook and turned it will bind both against the hook and the wire, substantially as described.
said clamp being adapted to be placed together with the wire between them while the wire is in. the hook, and then slipped laterally through the hook, and afterward turned, and said clamp having its circumference constructed with a projection which binds against the hooks when the clamp is turned and locks the latter in contact with both the hook and the wire, substantially as described.
' 3. The combination of a hook and a divided clamp elliptical or cam-like in cross-section and lined with insulating material, substantially as described.
4. The combination of a hook and a divided clamp elliptical or canrlike in cross-section and lined with insulating material, said clamp having an angular head, 0, for receiving a wrench, the sections composing the clamp being adapted to be placed together upon the wire while the latter is in the hook, and then slipped laterally through the hook and turned, substantially as described.
