Electrical Supply Company introduces a line of new brackets

Insulation Brackets.

The progress made in the last two years in line construction and in devices used in the work, has been marked. The construction of electric light, telegraph and telephone lines under all conditions in pole and housetop work seems to have been carefully studied, and the required devices may be readily obtained. In this connection considerations of high insulation are of the most vital importance. Electric companies

have found that high insulation is a great essential of commercial success. Illustrated herewith is a complete system of special wire brackets and appliances. The brackets possess advantages over the ordinary insulator support and sockets, in that the insulator itself is always held in an absolutely upright position, so that moisture cannot get under it and destroy its insulating properties. They are adapted for the use of any standard insulator.

Figs. 1 and 2 show a new form of loop or spreader bracket, the former for lateral attachment, and the latter being for forward projection. These are attached upon cross-arms or other suitable supports, and take the wires from the insulators upon the cross-arms, forming the terminal of the service loop. Fig. 3 shows a wall bracket for brick, stone or other walls. The wires are led from the spreader arms to these wall brackets, thence down to the window, service wires, converter, or other devices to be supplied. Fig. 4 represents an offset roof bracket, by means of which insulators are securely fastened to roofs or attached to cornices for the purpose of leading down wires at the edge of the cornice, at a considerable distance from it, or from the walls. Fig. 5 represents a straight roof bracket, the purpose of which is the same

as Fig. 4. It is also useful for utilizing the extreme top ends of uprights upon roofs and walls which are used in supporting cross-arms. Fig. 6 is a cornice bracket. It is often very difficult to secure insulators upon cornices without inverting the insulator or holding it at such an angle that the moisture will destroy its insulating properties, but by the use of this bracket the insulator maybe supported in an upright position, and yet project at any desired angle. Figs. 7 and 8 are lateral brackets, which are used for corners of buildings. They are made both right and left, and may be fastened to stone, brick, or other walls, supporting the insulators always in an upright position. The bracket's are put on the market by the Electrical Supply company of Chicago.
