Letters Patent No. 9( ),949, dated June 8, 1869.

IMPROVEMENT IN LIGHTNING-RODS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, THEODORE T. KINSEY, of Philadelphia, Pennsylvania, have invented'a new and us ful Lightning-0onductor and I do hereby declare that the following is a full and exact description thereof, reference being bad to the annexed drawings, forming part hereof, in which p I Figure 1 is a perspective view of two 'sections of the conductor united.

Figure 2, a' similar view of the same sections separated, this view being intended to exhibit the recesses formed in thestrips, or plates of one section, to facilitate the uniting of any two contiguous sections.

My invention consists of a lightning-conductor, the body of which is formed of strips of sheet-copper or iron, first severally folded longitudinally so as to form a triangle or angle, then fastened together with rivets inserted through the angles at short intervals, the whole being then twisted so that the several strips assume the spiral form shown in the drawings; or the conductor may consist of any number of separate sec tions, each composed of folded strips, as aforesaid, the several sections employed being then joined at their ends, in' the manner illustrated in the drawings, and the whole being then twisted as aforesaid.

In the drawingswire, as at g, fig. 1.

a represents one strip, and b, the other strip, they being each folded longitudinally, as shown.

a are the rivets by which the folded strips are fast, ened together.

When two sections are intended to be united, each of the strips of one of such sections has a narrow slot, (1, fig. 2, about one-half inch in depth, formed in it.

The ends of the strips of the other section are then inserted in the slots (1, and the two sections arefirmly united, either with rivets, as at f, or by being tied with I prefer to use rivets for this purpose.

No point or head of the conductor is represented, but the ordinary point is riveted, or otherwise atfixed to the body of the conductor.

Having thus described my invention,

I claim, and desire to secure by Letters Patent A lightning-conductor, the body of which consists of two strips of sheet-metal folded longitudinally, riveted together through their angles, and twisted into a spiral form, substantially as set forth.

THEODORE '1. KINSEY.
