LIGHTNING CONDUCTOR.

THOMAS H. DODGE, OF YVORCESTER, MASSACHUSETTS.
LlGHTNlNG CONDUCTOR.
SPECIFICATION forming part of Letters Patent No. 289,076, dated November 27, i883 Application filed April To aZZ whom it may concern:
Be it known that I, THOMAS H. DODGE, of the city and county of W'orcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Lightning or Electric Conductors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figurel representsasection of myimproved device. Figs. 2, 3, 4, and 5 represent. upon an enlarged scale, views of the parts shown in Fig. 1, as will be hereinafter described.
To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe the device more in detail.
The nature of my invention consists in the special mode or manner of constructing the body of the electric receiving or discharging parts.
' In the drawings, the part marked A represents a twisted-wire cable, composed in this instance of two wires, B B, one of which I prefer to make of copper, and C the electric or lightning receiving parts, which parts I prefer to make of copper wire of large size-say of No. 9 gage. The part 0 by preference is cut with pointed ends D D, and also has four projections, E E E E, pressed out, two on the upper and two on the under side thereof. It also has two other projections, F F, one on the front and the other on the rear side of the piece, as fully shown in the drawings. Vhen the stran d-wires B B are twisted together, the pieces 0 are fed in, so that the wires B B will pass one over the round part G and between the projections E E, while the other wire passes under the round part H and between the projections EE. Consequently when the wires are cabled the pieces 0 are held securely I 21, 1883. (No model.)
in place, while at the same time the projections F F fit into the crotches or angles formed by the wires when cabled about the pieces 0, as fully indicated in the drawings, the projections E E E E preventing longitudinal movement of the parts 0, and the projections F F rotary motion. In addition, the projections F F serve to conduct the electric fluid forward and back, and to both wires.
This cable may be utilized both as an elec* tric conductor and a trellis-wire for vines to run on, the parts 0 forming good supports to the runners of the vines. The product can be wound upon spools and handled very conveniently.
If preferred, one of the projections F or F may be omitted, and permit the wires on the side where the projection is omitted to twist up close against the body of the part 0. The projections may be punched or forced out by machinery in a very quick and expeditious manner, the machinery being so arranged that the operation of punching, feeding in, and cutting off the pieces may all be automatic.
It will be seen that the pieces Care stiffened and not weakened by reason of the projections, since the metal. is forced into such form as to brace the central portions thereof.
Having described myinvention, what I claim as new, and desire to secure by Letters Patent, 1s
The combination, with the cabled wires, of the metallic part 0, provided with projections E E E E, and also with proj ectionsFF, which latter projections prevent the part from turning in the cabled wires, substantially as described.
