' Be it known that I, JOHN S. Swanson, a citizen of the United States, residing at Cresco, in the county ofI-Ioward and State of Iowa, have invented new and useful'Im provements in Lightning-Rod High 'Tops,

. of which-the following is a specification.

This invention provides a high .top for lightning conductors and aims to devise .novel connecting and. bracing means whereby a close joint is maintained between the top and conductor and such topis stayed from every direction so as to preserve a givenposition.

The'invention resides the connecting 'means. between the top and conductor, and the peculiar form of brace for holding the.

' top in vertical position, the several partsbeing attractive,light, durable and effective for the purpose intended.

' The drawingillustrates an embodiment of the invention and it is to be understood that within the scope of the invention as claimed various changes in the tform, proportion and minor details may be resorted to without departing from the spirit of the invention. "Referring to the attached drawing,.Fig-

ure 1 is a perspective viewof a high top for lightning conductors illustrating the appli-' cation ofv the inaction. Fig. 2 is a sectional view of the lower portion ofthe'top;

3 is a'- detail view of ,the brace.

Corresponding and like parts are indicated inth'e several viewsby the same reference characters, like reference characters a being employed in the following description toindicate corresponding parts. 4

The top "1 preferably consists of a tube and is usually above five feet in length,

said top being pointed at its upper end and having a coupling 2 fitted to its lower end for making connection with the lightning conductor 3 which'may consist 'of'a copper cable or other form of, conductor commonly employed for carrying, ofi' atmosphericcharges of electricity. j: The coupling 2 com-' prises, an annular member fitted on' the conductor 3 and the vertical'projection b adapts ed to be received by the top 1, the latter being provided with an instruck tongue c for engagement with the shoulders of the' porjectionb 'to retain the pai ts operatively associated. The coupling 2on gages theconductor 3 which is connected joint. .A

is formed with opposedbraces 5' which lover} lie the conductor 3 and are secured thereto and to the structure 6 to which the lightning,

appliance is fitted.- The stay-piece 4 consists preferably at a length of tube which is adapted to slip uponthe top, saidtube having its .lower portion formed with a longitudinal slit,' the parts thus separated being bent in opposite directions to form the braces '5 which are secured, by means of staples 7 or like fastenings, to the structure 6. The

same fastenings 7 also serve to secure the conductor 3 to the structure 6.

top 1 and consists-of an up er ring 8, a lower ring 9 and a plurality oi legs 10, such legs having their upper portions engaged with the rings 8 and 9 and their lower portibns oppositely inclined and adapted to be secured at their lower ends to the structure 6. The top 1 and stay-piece 4 are usually consist of light rods whose upper ends are 'attached to the rings 8 andg9 by passing through openings formed therein. The rings 8 and 9 have a comparatively closefit with the top 1 so as to prevent any play. It is to be understood that the legs IO-maybe provided in any number inorder'to brace the top in each direction. a o

It is noted that the- 'stay-piece 4 constitutes positive connecting means between the top and conductor and also serves; to hold the ,A brace stays the upper portion of the" of copper whereas the brace is" generally formed of galvanized iron. The legs 10 may- 'top in the required position both with reference to the structure 6 and'the conductor 3.

The brace consisting of the the rings 8 and 9 and the legs 10 acts solely as staying (the invention appertains, and while I have,

' described the principle of operation of the invention, together. with the device which I now consider 'to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and

that such changes may be made when desired as are within the scope of the invention as claimed. I 1

Having thus described the invention what is claimed as new, is

2. In combination, a lightning conductor, 'a tubular top therefor having its lower end d ing said conductor,

the branches thereto.
