TO ALL WHOM IT MAY CONCERN:
Be it known that we, Tuonns J. Loexuanr and Josrnu LOCKE, of the city of Pittsburg, gheny, and State of Pennsylvania, have invented a new and improved Insulators to slate roofs, by which damage to the slates is prevented, and danger of causing leaky root's obviated; and we hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.
e construct our insulators in any of the known forms. The shape which we most generally use is represented inthc accompanying drawings; and to this insulator we have attached our shank for slate roofs."
Figure No. 1 is a perspective view.
Figure No. 2 is a transverse section.
Figure No. 3 is a longitudinal elevation.
A is the glass insulator which supports the lightning-rodv B. copper wires, .0 C, which pass through a hole in the insulator, and are twisted together on the outside of the rod. The insulator has a lip over which is fitted a malleable-iron collar, D, with ears having holes. is riveted through the ears to a galvanized sheet-iron shank, E; This shank may be twelve inches, more or less, in length, and two inches, more or less, in width. After the insulators are attached, by collars riveted to the shank, this shank may be fastened to the roof at the time the slates are fastened. The same nail used for nailing the slate may also be used for fastening the shank at the upper end marked thus: 0-the lower end projecting below the lower edge of the slate. If the slates are on the roof when it is desired to put on the lightning rod, in such case this shank E may have its upper end pushed underneath and between the flat surfaces of the slates, without injury to the slates, and which shank will thus be held securely; other insulators being fastened by screws or nails, in the ordinary manner, upon the chimney, apex, and cornice, or other parts of the building not covered with slate, tho lightning-rod is then attached to all these insulators and held securely.
county of Alle- Mode of Attaching Lightning-Rod The rod is secured to the insulator by two The collar What we claim, and desire to secure by Letters Patent, is-- The application to lightning-rod insulators of the metallic shank E, as herein stantially the same, and which will produce the intended efi'ect.
