WILLIAM G PIKE, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 70,741, dated November 12, 1867.

IMPROVEMENT IN LIGHTNING-GONDUGTORS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, IVILIZIAM G. PIKE, of the city of Philadelphia, State of Pennsylvania, have invented a new and useful Lightning-Conductor; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being bad to the annexed drawing, forming part hereof, and to the letters of reference marked thereon.

The drawing represents the conductor partly in perspective and partly in section.

My invention consists of a woven, braided, or plaited wire, in the shape of a cylindrical or flattened tube, or a gasket, terminated, in each instance, by a solid metallic point, and insulated, and connected with the ground in the ordinary manner.

In the drawing, a is the wire tube; 6 is the solid point; a is a solid rod, inserted in the upper end of the wire tube a, to support that portion of the same which extends above the building or other object to be protected. d d d are insulators, secured by staples in the ordinary manner. e is an angular short rod, employed where it is desired to connect a. .branch tube to the main tube a, it being provided with notches or recesses e and holes f, the different wire tubes employed being fastened to the rod e by wire, which is wound around the rod in the recesses, and theends passed through holes, as represented at g.

It is to be understood that the conductor may extend to any length, may have any desired number of branches, and may have, at its upper extremity, any desired number of points.

Instead of employing the angular rod 0 where it is desired to connect dificrent branches of the conductor,

this rod may be dispensed with, and the connection secured by passing the end of one branch of the conductor around the other branch.

Having thus described my invention, I claim, and desire to secure by Letters Patent 1. A lightning-conductor consisting of a cylindrical or flattened tube or gasket of Woven, braided, or plaited wire, terminated at its upper end by a solid point, substantially as-shown and described.

2. The angular rod e, for connecting separate branches of the tubular conductor, constructed substantially as set forth.

3. The combination of the wire tube a, solid point I), inserted rod 0, and insulators d, arranged and constructed in the manner and for the purpose substantially as set forth.
