WILLIAM B. BRAGDON, or CUMBERLAND MILLS, MAINE.
ELECTRIC-WIRE SUPPORT.
SPECIFICATION forming part of Letters Patent No. 479,052, dated July 19, 1892.
I Application filed March 4, 1892. $erial No. 423,760- (No model.)
To aZZ whom it may concern:
Be it known that I, WILLIAM B. BRAeDoN, a citizen of the United States, residing at Cumberland Mills, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Tripods for Supporting Electric-Wire Insulators; 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to certain new and useful improvements in devices for supporting electric wires; and it has for its object to provide a simple form of tripod, which is designed especially for use in conducting wires over the roofs of buildings.
The device is simple and cheap of construction, of few parts, and adapted to be readily put up, and when not required for use the several parts may be separated and packed within small space, thus rendering it convenient for storage or transportation.
To these ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.
The invention is fully illustratedin the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, like letters of reference indicating the same parts throughout the several views, and in which drawings- Figure 1 is a side view of a wire-supporting tripod embodying my improvements. Figs. 2, 3, 4E, and 5 are enlarged detail views of the several castings, which will be more particularly hereinafter referred to.
Reference now being had to the details of the drawings by letter, A represents an ordinary cross-bar, such as is commonly employed for supporting electric wire insulators, as shown at A. This cross-bar is supported upon the tripod consisting of the castings B O, the rods or legs E, and the castings D,
which form the feet or supports for the legs or rods E.
Each of the castings D consists of a base portion d, which may be either of the circular form shown, or, if preferred, may be rectangular and provided at intervals around its outer edge with recesses d, within which are placed the nails, bolts, or screws which are employed in securing the casting to the roof of the build ing. The body portion 6 of the casting is inclined at an angle from the base portion, is hollow to permit of the passage of the rod E, and is provided with an enlarged chamber 6 for the reception of the nut e upon the lower end of the rod. 7
The casting 0 consists of a body portion 0, having at its center an opening 0 for the passage of the bolt which is used in securing to gether the parts of the tripod, as will be presently explained, and atits outer edge the bifurcated and slightly-upwardly-inclined arms or projections 0 The upper ends of the legs or rods E are received within the bifurcations of the said arms 0 and are retained therein by means of the nuts 0 which are placed upon the said rods both above and below the arms.
The casting B, which forms a support for the cross-bar A, consists of the body portion B, having at its ends upwardlyextended arms or projections B which engage openings provided for their reception in thelower face of the cross-bar, and upon the lowerface of the said casting B are provided a series of bosses or projections B which engage corresponding apertures in the casting O.
In assembling the parts the castings D are first secured to the lower ends of the rods E. The casting O is next attached to the upper ends ofthe rods. The part B is then placed upon the upper face of the casting O, and upon said casting B is placed the cross-bar A. A bolt G is then passed through the cross-bar A and extended downward through openings in the castings B and O, and the parts thus united are drawn securely together by means of a nut upon the upper end of the rod G, as shown.
Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is
1. In a device of the character described, in combination, the rods E, the castings D, forming the feet of the tripod and adapted to be bolted to the lower ends of the rods E, and the casting C, having body portion C'and inclined bifurcated arms, the upper ends of the rods being secured within the bifurcations of said arms by nuts upon the rods, substantially as described, and for the purpose specified.
2. The herein-described tripod for supportingelectric-Wireinsulators, the same comprising, in combination, the rods E, forming the legs of the tripod, the castings D, detachably secured to the lower ends of the rods E and adapted to be secured to the roof of a building, the casting 0, having inclined bifurcated arms to receive the upper ends of the rods E, the nuts 0 upon said rods, the casting B, having upwardly-extended arms or projections B and bosses B upon its lower face, said bosses being adapted to engage recesses in the casting 0, the cross-bar A, seated upon the casting B, and the bolt G, passed through said cross-bar and castings and serving to hold the same together, substantially as described.
In testimony whereof I affix my signature in presence of two Witnesses.
