TFEET ER-W INSULATDR.
Specification of Letters Patent.
Patented Nov. 10, 1908.
Application filed may 20, 1903. Serial No. 433,880.
T all whom it may; concern:
Be it known that Grotto-Elli. FINCKEL, a citizen of the United States, residing at C0- luinhus in the county of F 'anklin and Stat of Ohio, have invented a certain new and useful Improvement in i eeder-Viire Insulators, of which the following is a specification.
The object of this invention is to provide an improved insulator especially adapted for feeder or other electric wires.
The invention consists in the construction hereinafter described and then particularly pointed out in the claims.
lu the accompanying drawings illustrat- Eng forms of the invention, but to which .tornis the invention is not lin1ited-Figure 1 shows in elevation the device ith the parts assembled; Fig. 2 is a plan view looking at the upper end of Fig. lrhigi 3 is a ient'ralsection on the line Fig. Fig. 'i is a similar section on the line 3y--3/ Fig. 5 Fig. 5 is a plan view looking at the inner end of the insulator body or the under side at the device as viewed in Fig. 4; Fig. 6 is an elevation of the pin; Fig. 7 is a View lo king at the upper end or the pin, and Fig s is a sectional. view like Fig. of anoth r form of insulator oody.
'lhc insulator body 8 is formed of the usual material, as porcelain, glass or other vitreous material. The insulator body has a ventral circularwuacning 9 with a key way or groove it). The inner end of the central opening is shown to he enlarged to torni a socketll. the shoulder l 2 between the socket H and opening 9 being or spiral form. The ext rior of the insulator hody is Formed with the usual annular groove 13 to receive the elm-tritcondiud'or or devices for attaching lilo l-ointiu'tor thereto.
l t designates the metallic pin, preferably tlutmf and barbed at one end to form a spur as seen at l5 and provided with a small r 'iiudriral portion It? at the other to fit. in tit" opening 5) ot the insulator body. 'lhc spur is to ho driven into the coal or other wall as asuat The portion in is provided at ts end with a laterally projecting lug 17. \t the haso of" the portion '16 is a shoulder If at a dia water to lit in the socket 11, said shoulder having its outer side of spiral form as m n at l.) corresponding substantially in pit h to the pitch of the shoulder 12 in tho :uiator hody.
The insulator body is placed on the small or reduced end 16 of the pin by sliding it thereon with the lug 17 in line with the key way or groove 13 until the lug lies hayond the outer end of the insulator body and then giving it a turn to tightly pinch the body between the spiral surface and lug of the pin. It is understood, of course, that the lug should he located-at such a distance from the spiral shoulder 10 as to require the lug 17 to be turned out of line with the groove 13 to obtain the pinching effect. One of the important advantages of this construction is that the spiral shoulders of the insulator body and pin afford large contacting surfaces thereby giving a firmer binding ellect he tween the insulator body and the pin. By diminishing the pitch of the spiral contacting surfaces and placing the pin a trifle nearer the spiral surface of the 'pin the binding effect might be increased Another important advantage of this construction in The shoulder between the large and smallopenings of the body can be provided at the proper point with a small non-spiral por tion, as seen at 20, Fig. 8, to cooperate with the spiral shoulder of the pin. llut l, at
p'cscnt, prefer the two spiral surfaces, one
on the pin and one on the block as first set forth, because of the more extended contact. between the parts.
lVhat i claim and desire to secure by lictitors Patent is:
l. The combination with an insulator body havlug a through opening provided with a key way and a shoulder at. the inner end of said opening, of a supporting pin having a holly engaging portion provided with a lug to pass through said opening and key way, said lug to engage when turned the outer end oi the insulator body, said pin also provided with a spiral shoi-ddcr against which the shoulder at the inner end ot the insulator hody is turned, substantially as described.
2. lhc(coinhiiuition with an insulator body having a through opening proviihrd with a key way and a spiral surt'arc around the inner and of said opening. ot' a supporting pin having a body-engaging portion provided llt) with a lug to pass through said opening and key way, said lug to engage, when turned, the outer end of the insulator bod said pin also provided with a spiral shoul er against which the spiral shoulder of the insulator bodyis turned, substantially as described.
3. The combination with an insulator body 'having a through openin provided with a key way, and a spiral surface aroundthe inner end of said opening, of a supportlng in having a body engaging portion provi ed with a lug to pass through said opening and key Way, said lug to engage, when turned, the outer end of the insulator body, said pin also provided with a shoulder at the base oil; the body engaging portion against which said spiral surface in the insulator b0. 1 is turned, substantiall as described.
