CONDUCTOR SUPPORT AND INSULATOR.

SPECIFICATION forming part of Letters Patent No. 503,519, dated August 15, 1893.

Application filed May 15, 1893. gerial No. 474,220. on model.)

To all whom it may concern.-

Be it known that I, DAVID T. BENNETT, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Electric Conductors and Fastenings for the Same; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to an improvement in electric conductors and fastenings for the same, together with an improvement in insulators, to be used on electric railroads, either overhead, underground, or surface lines, and the novelty will be fully understood from the following description and claims when taken in connection with the annexed drawings, in which- Figure 1, is a side view, partly in section of a part of a conductor,the holding or connecting device and insulator,in a position as used on a surface or underground line. Fig. 2, is a side elevation of the improvements in a position as used on an overhead line. Fig. 3, is a perspective view of the bracket for receiving and connecting the conductor. Fig. 4:, is a perspective, detail view of one of the conductors, in section. Fig. 5, is an elevation with the conductor in section showing the improvements in an overhead system. Fig. 6, is a perspective view of the insulator holder, removed.

Referring byletter to said drawings: A, indicates the conductors. These conductors are of a form substantially as shown, and are made from copper or other suitable material, having a rolled head a, and a web or flange Z). These conductors which are solid, may be of any suitable length, and thickness; the diameter of course depending upon the force of current to be conducted. The webs or flanges Z), of the conductors, are provided at a suitable point from their ends, with transverse holes 0, which are designed to register with holes (1, in the bracket to receive connecting bolts 6, which may be secured in position by means of nuts f, or other suitable fastening devices.

13, indicates the bracket for connecting and supporting the contiguous ends of two conductor sections. This bracket as better shown in Fig. 1, of the drawings, has a head g, provided with a longitudinal, angular slot or recess h, of a shape corresponding with the web or flange b, of the conductors and is designed to receive the same. The walls 2', of this slotted or recessed head have the holes (Z, arranged in alignment and are designed to register with the holes 0, in the conductor sections when said sections are to be connected and secured by the transverse bolts. This head is provided centrally on the opposite side from the slot and in a plane at right angles thereto, with a stem 70, which is screw threaded at its outer or free end as shown at Z, and may have a shoulder m, at its opposite end formed integral with or contiguous to the head g. Arranged upon this stem 71:, is an insulator G, which maybe formed from porcelain, glass, rubber, or other suitable non-conducting material. This insulator,has a central, longitudinal aperture n, to receive said stem,and the insulator may be provided on its opposite outer side, with annular shoulders 19, to receive a band D, between them. This band may be formed from copper or other suitable material, and is provided on its outer side with diametrically arranged arms q,having apertures r, in their outer ends to receive bolts or other suitable means for connecting them to a support.

As illustrated in Fig. 1, of the drawings, I have shown a base E, which may be that of a cross tie as used on a surface or underground road. Secured on this tie or support is a plate F, and rising from this plate are two parallel standards G, which are reduced and threaded at their upper ends as shown at K, to receive nuts L, after passing through the apertures or holes r, of the arms q.

As shown in Figs. 2, and 5, of the drawings, where the improvements are to be used on an overhead cable road, I dispense with the standards and connect the arms q, with the cross wires M, extending from the poles N, which are usually employed.

The longitudinal edges of the walls 71,0f the clamp are beveled as shown so that they will bear snugly against the under side of the head of the conductors and absolutely close any tendency there might be in the opening of the circuit due to the separation of parts.

With a device of the construction described, I get a very smooth surface for the trolley.

The parts are firmly secured and held in position, and are not liable to become impaired or injured, and should a break occur in any part of the conductor it is obvious that the joint might be made by one of the clamping brackets and connecting parts; it being simply necessary to punch holes through the flanges of the contiguous sections, when they can be connected and secured in the brackets by means of the transverse bolts.

Having described my invention, What I claim is- 1. The combination with two sections of an electric conductor, having a head a, and a web or flange b, and also having perforations through the Web; of the bracket having the slot and also having holes to register with the holes or apertures in the web of the conductor, and provided with a threaded stem, the insulator surrounding the stem, the nut for securing the stem to the insulator, the band em-.

bracing the insulator, and having perforated branches, posts having" threaded ends and entering the apertures in said branches, and nuts or the like for securing the branches to the bolts, substantially as specified.

2. The combination with a conductor; of the bracket having the threaded stem is, the insulator c, surrounding said stem, and havingthe shoulders 10, on opposite ends, the band D, embracing the insulator, and arranged be tween the shoulders thereof, and provided with the diametrically arranged arms q, bolts and nuts secured to said arms, and suitable supporting means for the attachment of said bolts, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID T. BENNETT.
