which form a part of this specification.

To all whom it may concern: base in any suitable manner as for instance Be it known that I, EUGENE W. VOGEL, a by bolts t) extending through the base citizen of the United States, residing at Chiand upwardly throng the posts. The heads cago, county of Cook, State of Illinois, have of the bolts are preferably located in recesses so invented a certain new and useful lniprovel in the under surface of the basemerit in Lightning-Arresters, and declare the i In order to prevent the posts from rotattollowing to be a full, clear, and exact tleing relatively to the base, dowel pins such scription of the same, such as will enable indicated at may, it desired, be formed on others skilled in the art. to which it perthe lower ends 01'? the posts andreceivcd in tains to make and use the same, reference sockets in the plate.

The posts may be secured to the l The operation of my invention is as fol lows: The device is located at any desired point and may be supported by screws extending through holes a 1n the base plate.

The base plate is preferably loosely connected with its support as the arrester 18 less] passes from the circuit through the coil 1* it will be choked or retarded so that it will pass from the convolutions of the coil F to the plate H and thence to the ground. The

current may also be grounded by passing directly from the posts B B to the plate H without passing through the coil F in which event the teeth on the ends of the plate H facilitate the passage of the lightning from the posts to the plate.

The strain to which the arrester is subjected by the passage of lightning therethrough would result in the breaking of the insulating tube G were it not for the cushioning effect of the end caps g g interposed between its ends and the posts.

From the foregoing description it will be observed that I have invented an improved lightning arrester which though simple and inexpensive in manufacture is durable and efficient in use.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a lightning arrester, the combination with a base of insulating material, a pair'of posts of conducting material supported on said base, a conducting coil of wire interposed between and secured at its ends to said posts, and a ground conductor supported on said base in proximity to said coil and having its ends projecting into proximity to said posts.

2. In a lightningarrester, a base of insulating material, a pair of posts of conduct ing material on said base, a conducting coil of wire interposed between said posts, a pair of bolts passing through said base and securing the ends of the coil to the posts and the posts to the base, and a ground conductor supported on said base in proximity to said coil and having its ends projecting into proximity to said post.

In testimony whereof, I sign this specification in the presence of two witnesses.
