ELECTRIC SWITCH.

SPECIFICATION forming part of Letters Patent No. 582,825, dated August 8, 1893.

Applicationl filedhAngnst 2 2,

rier adapted to be slid horizontally in`connec.

tion with contact membersin line with the ends of said carrier. I attain these objects by the construction illustrated in the accompanying drawings in which- Figure l is a perspective view of an electric switch constructed in accordance with myinvention. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a longitudinal central section of a slightly modified form of electric switch, the modification consisting in attaching one of the wireholding jaws to the longitudinally movable switch-bolt. Fig. 4 isv a top vie'w of a double wire switch constructed in accordance with my invention. Fig.l 5 is a top view of a modification of the means to gperate the longitudinally movable switcholt. .V

In said drawings A represents the support base block of the switch.A Said block is preferably of porcelain or other wellknown nonconducting material. To the top of saidv block, about the centerthereof, the switchbolt Bis located. Said'bolt is guided by two arched metal straps C that are secured on top of the block A. Said straps are also preferably united together on one side by a bar C? that pivot-ally receives the pivot bolt d of an eccentric D used to longitudinally slide the switch-bolt B, that has a mortise cut in its top to receive the eccentric D. Said eccentricis controlled and operated by a lever E that has one end secured to the eccentric by means of the bolt d that is pivotally connected with the bar C2. The opposite end of said lever is provided with a handle e of insulating material and the portion adjacent to said handle is received into one of the notches f of the leverretaining plate F. The latter is preferably sesam. 443.741. (No modela a sleeveG thathas its inner end preferably slotted longitudinally to form spring lingers g' that constantly retain one end of the switchbolt in electrical `connection with the sleeve .although said bolt may be easily moved longitudinally along the inner surface of the tingers g. The sleeve Gis secured on top of the tudiiiallylslott'edl or removed, to give to its lower half or jaw a trough-like form G2 to receive one vot the wire conductors H used with the switch. The interior of said trough is preferably provided with teeth ga, and to the inner end of said trough is pivoted a jaw G3 that has serrations g3 on its under side for engagement` with the conductor H. To promptly adj ust and retainsaid jaw GS in engagement with said conductor, an internally smooth ring I is made to encircle the jaws G2 Gand to retain said ring at a proper distance from the pivot of the jaw G3, said ring has lugs t' projecting from its periphery to which is pivoted "a dog 2 that has its inner end in engagement withY teeth or notches g4 made in the top edge of the jaw G3. A spring s secured to thedring and Ahaving its outer end pressing against the turned up tail off,I

the dog retains the latter in engagement with the notches g4. And as the jaw G3 is vertically WiderV toward its outer end,whenr the ring is toward that end, 4the conductor becomes strongly retained clasped between the jaws. In front of the opposite end/of the `switch-bolt B, there is secured to theblock A,

a Vsleeve K, by means of screws passing through lugs k projecting from its sides. The interior diameter of said sleeve is larger than vthe diameter of the boltl B at that end,"so that electrical connection when it'o'ccurs, will take place only with its end and not with its sides.

and prevent sparking when the switch-boltis withdrawn from the sleeve. The disk k2 is retained and guided within the sleeve bylugs 7a4 passing through short slots 7.95 in the sides of sleeve K. Said sleeve is provided with a trough-like jaw G2, a serrated jaw G3 and a ring and dog as described for the sleeve G.

In Fig. 3 the jaws G2 G3 are attached directly to one end of the switch-bolt B, and a bend or loop is preferably made in the conductor II so that said loop will be easily bent and thus lengthened or shortened in operating the bolt.

In Fig. 4 the eccentric is made double to operate at the same instant two switch-bolts with sleeve K that are placed at diagonal corners of the block A.

In Fig. 5 the switch-bolt B is longitudinally guided by a metal strap C secured to the block A, but its inner end is connected with the sleeve G by means of toggle-levers m m2 and operated by ahandle m3 connected thereto at the point where said levers are hinged to each other.

Having fully described my invention, I claim- 1. In a circuit controlling device or switch, the combination of a circuit terminal having its inner end longitudinally slitted and its outer end provided with a trough-like jaw and a pivoted jaw provided with teeth on its top and bottom edge, a ring and pivoted dog riding on the pivoted jaw, a second circuit terminal provided with a trough-like jaw, a toothed pivoted jaw, and a ring and dog thereon,with a longitudinally sliding switchbolt permanently in electric connection with one of the circuit terminals, and` means to slide said bolt substantially as described.

2. In a circuit controlling device or switch, the combination of a horizontally sliding switch-bolt permanently in electrical connection at one end with a pair of jaws closed by a ring, and at the other end with a circuitterminal having a pair of jaws at its outer end, and in its inner end a cavity of larger diameter than the end of the switch-bolt substantially as described. Y

3. In a circuit, controlling device or switch, the combination `of a horizontally sliding switch-bolt permanently in electrical connec tion at one end with a circuit terminal, and

at the other with a circuit terminal having a pair of jaws at its outer end, and within the inner end a cavity of larger diameter than the end of the switch-bolt, and a disk and spring within said cavity substantially as described.

ll. In a circuit controlling device or switch, the combination of a horizontally sliding switch-bolt, with circuit terminals in line with said bolt, each terminal having a trough like jaw, a pivoted jaw provided with teeth on its upper edge a ring encircling said jaws and a spring dog pivoted to said ring substantially as described.

In testimony whereof Iaix my signature in presence of two witnesses.
