GEORGE ROW, OF II DIANA, PENNSYLVANIA Letters Patent No. 109,455, dated November 22, 1870.
IMPRQVEMENT LlGHTEdlNG-RQDS.
The $chedule referred .li'atn're and Objects of the ll-zeemon.
The first part of my invention relate construct- 'ing a lightning-rod oi sheet-copper of onvenient size by series of 'plications or inverse folds or plain; running longitudinally and lightly pressed down, leavinssmall "vacuums or spaces intervening the folds whereby the conduction surface of the rod is largely increased, the extent of such surface being; limited on by the number and breadth of the folds 'ihc rod also twisted spirally, adding to its symmetry and preventing the folds being opened, thereby strengthening it. The point section, or tliatpart, which may extend above the building or other object upon which it, may be erected, may he further strengthened by i sci-ting between the outer folds or leaves as many wires shall be necessary to insure the desired result.
The second part of my invention relates to the man-- ner,as Sll0\\l],0f joining together the respective pieces or sections of rod, make as above described, said joint-s or connect-ions being formed by cutting away a portion of the back of the respective folds at one end ofeaen sectional part of the rod, separating the leaves, and creating a shoulder to meet the ends of the connecting section; then, by taking the ends of the several sections of red thus prepared, and inserting the separated leaves or folds into the interstices of the eonmeeting," s :,tion, a substantial joint is effected, whichis thus fully secured by common copper rivet.
.Dcseripioe of Drawing.
Figure 1 represents a sectional part of the rod, showing the several folds A, the Width of the folds l3, and rivetdioles for fastening joints 0.
Figure 2 illnstn es the sections joined, the transve. e line exhibiting the point ofjunction with the istening a ;ure 3 represents the head of section with the hacks or folds cut, down, fern-linga shoulde and. se ne ratin the leaves.
Figure l illustrates the foot, of section, showing spaces between folds, into which the separated leaves, as shown in i 3, are inserted, forming the connections between the several sections.
Claims.
l claim as. any inVent-ioh ll. r-rlightning-rod, constructed of a series of plications or folds of metal, substantially as and for the purposes hereinbefore set forth.
The manner of connecting the several sectional parts, substantially as and for the purposes hereinbei'ore set ihrih.
