IMPROVEMENT IN LIGHTNING-RODS.

,msonsoniq' retenodtointhosowot'amtsndinsldngpmotthom To whom it may concern Be it known that I, LEWIS KING, of EastClereland,

' in the county of Ouyahoga and-State of Ohio, have invented certain new and useful Improvements in Lighthing-Rods; and Ido hereby declare that the following is a full andcomplete description'of the construct-ion of the same, reference being bad to the accompanying specification and of the some:

' Specification.

Figure 1 represents a portion of a lightning-rod. Figure 2 is a section of the same. Figures 8, 4, 5, and 6 are detached sections that will be referred to in the description.

Like letters of reference denote similar parts in the different views.

My improvement relates to'constructin a light-- ning-rod in such a manner that the joiutso the main rod and the joints at the junction of the branch parts of the rod'wit-h the main rod are made without links orousside projections, iormingone continuous rod that presents an unobstructed surface for the passage of Thcre'are various modcs of forming the joints rep- I resented in the drawing, and will be described as follows Where sections of a main or straight rod are L( be connected together, as the sections or pipes A and B,

a dowel, d, of any suitable form is screwedinto or otherwise secured in or .to the end of one rod or pipe, so that a part of the dowel or tenon joined on one section will project, onto which the end of the other i is screwed or fastened to form a close 'oint even P 1 J V a on the outside, and which is perfectly secure.

' In unitinghramch rods or pipes to a straight or main rod,as at B, one end of the dowel is screwed in the branch pipe or section D, as represented, and on the i projecting end of the dowel is placed acollar, f, fitting up close to the end. of the pipe D, being of the same shape and diameter across.

.TIIQ other end of the collar is curved out, as shown at e in figs. 1 and 6, which isa perspective view of the collar detached.

It is cutout in that form so as to fit close'arouud the rod A, and it is curved out more or less on either side,

according to the anglcthat thebranch rod is placed in reference to the rod with which it is to format junction.

The end of the dowei extending into the pipe A is formed into a head, 0, seen-in figs. 2 and 4, in which there is a hole or opening that a pin, g, in the pipe A is put through, whereby it is hcld'flrmly in place,

- that when the end of the pipe D is screwed onto the dowel against the collar, a perfectly close joint is the annexed drawing making a part Witnesses:

' y W. H. Bunnrncs,

Hnuur H. Roe.

formed in connection with the main rod Aand collar, as represented.

Another manner of forming and securing such 5.

joint is shown at F, in figs. 2, 3, and 6.

The end of the dowel extending into the pipe G is formed into a head, I, as clearly shown in fig. 6, which represents the dowel in the pipe G with the collar de-- tached. v I

The head is cut or notched out on the sides, as at a, so that the staple J, with two fingers or prongs, I, seen in fig. 3, put into the pipes G, will fit into the grooves or notches r, by which the dowel will be firmly secured in place.

The collar on the dowcl, which is the samqas the one before described, fits around the pipe G when the, branch pipe G is screwed onto the end of the dowel,

forming. close joints, as represented.

Still another form of srcuring such a joint is shown at H, in figs. 2 and 5, in which the inner end of the dowel is formed into a. fiat rounded head that is put B, and then turned at through aslot, n, in the pipe right angles to theslot, as shown in fig. 5, which holds the dowcl firmly, thereby securing a close joint when the collar is put on, and a pipe, L, screwed onto the dowel in the manner before stated.

In any of ,these ways as described joints can be formed at the junction of branch sections of the rod with one another where they come together at any angle, making a smooth, close, and secure joint, by which,

together with the manner of joining straight pipes directly, a continuous or branching rod is formed, with a perfectly smooth surface on the outside, which presents no obstruction to the passage of the electric currents.

Where these joints are formed in the ordinary way,

with links or projecting collars, the projectionsnre not only liable to obstruct the currents, but rain and wet lodge on them, which oxidize the metal,thereby producing an imperfect conductor, the dangerous conse-;'

quences of which are well known.

Claims.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The connection of branch pipes or tubular lights I niug-rods by means of the pin g, head 0, collar f, and dowel (l, substantially as and for the purpose set forth. f

2. The dowel or tenou d, in combination witli straight or main sections of tubular lightning-rods, substantially as and for the purpose set forth.
