Definitions
- the improvement in the construction of the insulator which I claim consists in making the inner surface convex as represented at A, C, Figures 1, 3 and 5, this With the outer conformation represented by the drawing presents a circular surface both inside and out making the thickness of the insulator uniform in all parts; a conformation which combines the greatest strength With the greatest economy of material, and by having the least possible amount of surface in contact With the rod and opposing the least possible resistance to the passage or expansion of air produced by the lightning renders less liable to be broken by the lightning or any other cause.

T. U. WEBB. INSULATOR AND FASTENING FOR LIGHTNING RODS.
No. 11,539. Patented Aug. 15, 1854.,
TIMOTHY U. WEBB, OF JERSEY CITY, NEW JERSEY.
INSULATOR FOB LIGHTNING-RODS.
Specification of Letters Patent No. 11,539, dated August 15, 1854.
To all whom it may concern:
Be it known that I, TIMOTHY U. WEBB, of Jersey City, in the county of Hudson, the State of New Jersey, have invented a new and Improved Mode of Insulating Lightning-Rods, and Securing the Insulators; and I do hereby declare that the following contains a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.
The improvement in the construction of the insulator, which I claim consists in making the inner surface convex as represented at A, C, Figures 1, 3 and 5, this With the outer conformation represented by the drawing presents a circular surface both inside and out making the thickness of the insulator uniform in all parts; a conformation Which combines the greatest strength With the greatest economy of material, and by having the least possible amount of surface in contact With the rod and opposing the least possible resistance to the passage or expansion of air produced by the lightning renders less liable to be broken by the lightning or any other cause.
I do not claim making the outside of the insulator With a horizontal groove in'the middle and a flange on each side of the groove but lVhat I claim is- Making the inner surface convex in the manner and for the purposes described.
TIMOTHY U. WEBB. Witnesses:
M. S. BREWSTER, FRANKLIN BROWN.
