LIGHTNING-ROD COUPLING. No.176,769. Patented May 2, 1876.
Attorney UNITED STATEs PATENT OFFICE.-
SYLVESTER BRADLEY, on BLooMIN'GToN, ILLINOIS.
IMPROVEMENT lN LlGHTNlNG-RbD COUPLINGS.
Specification forming part of Letters Patent No. 176,769, dated May 2, 1876; application filed October 4, 1875.
f To all whom it may concern:
Be it known that I, SYLVESTER BRADLEY, of Bloomington, in the county of McLean, and
in the State of Illinois, have invented certain new and useful Improvements in Lightning- Rod Coupling; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention consists in the construction and arrangementof a coupling for lightning-rods, as will be hereinafter more fully set forth.
- In order-to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- 1 igure 1 shows two detached sections of lightning-rod with the coupling therein. Fig. 2 is a longitudinal section of the same when coupled together. Fig. 3 is a perspective view of the coupling.
A and B represent two sections of a lightning-rod, constructed in any of the known and usual ways, and -to be connected together by means of a coupling constructed in the following manner:
The coupling consists of a male part, (J, and a female part, D, secured in the adjoining ends of the two sections A B. The male part (1 of the coupling is, at its'inner end, made large enough to fit in and be permanently secured to the end of the section A, the portion 0' of said-part 0 extending beyond the section A,
being turned down of smaller diameter, as shown. The female part D of the coupling fits in and is secured to the end of the lightning-rod section B, and has a central aperture for the passage of the part 0. In this aperture, on opposite sides, are longitudinal grooves 00 m for the passage of pins (1 a, which project from opposite sides of the part 0 near its end.
The inner end of the female partD is made with two inclines, I) b, as shown particularly in Fig. 3, so that'when the male part 0 G is inserted in the female part D and then turned around, the pins 11 a will move up said inclines b b, and bind the two parts of the coupling together, and thereby uniting the two sections In testimony that I claim the foregoing I have hereunto set my hand this 13th day of September, 1875. I
