BRACKET FOR INSULATING-SUPPORTS FOR ELECTRICAL CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 296,558, dated April 8, 1884.

Application filed November 30, 188.). (No model.)

To all whom it may concern:

Be it known that we, DAVID S. I-IAINEs, of the city and county of New York, and STEPHEN D. LAKE, of Brooklyn, county of Kings, both in the State of New York, have jointly invented certain new and useful Improvements in Brackets for InsulatingSupports for Electrical Conductors, of which the following is a specification.

This invention relates to certain improvements in the construction of brackets for receiving insulators for telegraphic and other electric conductors, and particularly an insulator of the character invented by us,for which application for Letters Patent has been made bearing even date with this. This insulator may be briefly described as being constructed in two cylindrical sections adapted to be placed and securely fastened with their ends against each other. The confronting ends are grooved to receive the conductors to be supported, and in the groove are formed lugs or projections adapted to bind the conductor tightly by forcing it out of astraight line. The sections of the insulators are provided with axial apertures, through which extends a spindle or support for holdingthe same in position.

Ourinvention consistsin constructing a supporting-bracket of iron or other suitable material in a form designed to secure strength, and provided with the necessary parts for rein any desired place. Brackets for similar purposes have heretofore been made of wood, which is liable to split, and, in order to be of sufficient strength, are necessarily so large as to be clumsy and unsightly. WVhere their use has been discontinued and their removal becomes necessary, they are apt to be so damaged by removal that they cannot be used again.

In the accompanying drawings, which illustrate'our invention, Figure 1 is a plan view of a double bracket; and Fig. 2 is a side elevation of the same, a portion being shown in section with an insulator applied. Fig. 3 is a plan view of a single bracket. Fig. etis a plan view of an angular form adapted to be placed upon the corners of buildings, and Fig. 5v is a side elevation of the same.

Referring to Figs. 1 and 2, A represents the base of the bracket, which is preferably made of malleable iron, although different metals or compositions may be used, if desired. The base A, which is of any convenient form or shape, is provided with a suitable number of holes, B, B, B, B, and B, for receiving the screws or nails which are used for securing the brackets to awall or other main support. The general surface of the base A is preferably depressed, as shown more clearly in the sectional View, Fig. 2, thus forming a ridge, 0, around the entire bracket, which serves to strengthen it. Slight elevations D and D", of a size corresponding to the insulating-supports G, which are to be placed upon them, are raised upon the depressed surface, and they may be of the same or greater height than the ridge O.

Extending from the centers of the raised surfaces D and D, respectively, are projections or spindles E E forming part of the bracket. These projections are drilled and tapped, as shown at f, for the admission of machine-screws .F. The projections E are somewhat shorter than the two sections of the insulating-support G which is placed upon it, in order that the screw may clamp the two sections firmly together, as shBwn in Fig. 2. In some cases, to secure greater strength, the So spindle may be omitted, the seat for the insulator raised somewhat more, and the screw may then be of the full size of the aperture formed in the insulator, and be screwed into the base. This construction is shown in the right-hand portion of Fig. 2.

Fig. 3 illustrates the invention as embodied in a single support. The various parts are constructed in substantially the same manner as has been described, and are indicated by corresponding reference-letters, and will therefore not require further description.

Figs. at and 5 represent the device arranged especially for attachment to the corners of buildings. The construction employed in this modification is essentially the same. The projection D however, preferably extends from the exterior angle formed by the two sides a,

and a of the main support A, instead of from the Hat surface of the same, thus holding the insulator in the position generally inost desired, when attached to the corner of any structure.

Other forms may be used, adapted to differ ent positions upon the surface or angles ofthc structure to which they are to be fastened.

\Ve claim as our invention 1. The combination, substantially as hereinbefore set forth, of aninsulator-braeket, means for securing the same to a support, a stem for receiving an insulator, and a serewfittinginto said stem and serving to bind said insulator upon said stem.

2. The combination, substantially ashereinbefore set forth, of the bracket A, having a stem, 1 the screw F, and the insulator G.

The combination, substantially ashercinbefore set forth, of an insulator-bracket, means for securing the same to a permanent support, a seat for an insulator raised upon the surface of said bracket, and means, substantially such as described for securing an insu- ]ator upon such seat.

In testimony whereof we have hereunto subscribed on r names this 28th day of November, A. l). .1883.
