INCANDESCENT ELECTRIC LAMP SWiTCl-l.
SPECIFICATION forming part of Letters Patent No 328,83l, dated Gctober 20, 1885. Application filed December 26, 1884. Serial No. 151,265. (No model.)
To all whom it may concern.-
Be it known that I, CRAIG R. ARNOLD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Switches for Electric Incandescent Lamps, of which the following is a specification, reference being had therein to the accompanying drawings, where- 1n Figure 1 is a sectional elevation of an electric incandescent lamp and switch mechanism therefor embodying my improvements.
Fig. 2 is an elevation of the switch-holder.
Fig. 3 is a vertical section of the same. Fig. 4 is a plan of switch-andlhorizontal section of the holder, and Fig. 5 is a horizontal section of the same.
My invention has relation to switching or circuit-connecting devices for electric incandescent lamps; and it has for its object to provide a simple and inexpensive construction of switch of extreme durability.
My invention accordingly consists in the combination, construction, and arrangements of parts as hereinafter described and claimed, having reference particularly to two fixed split or doubled jaw contact-points and a rotary switch so arranged that it makes and breaks circuit Without producing undue sparking.
In the drawings, A represents a tubular casing or holder with contracted or other form of neck or bottom a, through which lead the line-wires B B.
O 0 represent spring or other metal clamps, and D D the contact-points. One of these contact-points is connected to or forms part of clamp O, and the other contact-point is insulated from said clamps, which in turn are insulated from one another. Each contact point is split or composed of two fingers or jaws, d, which approach or incline toward each other at their outer ends, as more plainly shown in Figs. 4 and 5, and between the jaws of each contact-point rotates the switch E, it being supported upon or fixed to a pintle, e, having a turn-button, e, exterior to the holder A.
The wire B connects with contact-point D,
and wire B with clamp G, as shown, so that when the lamp indicated at F is in the holder A, with the leading wires of the former in contact with the clamps O O, and the switch E bridging or connecting the contacts D D, as illustrated in Fig. 1, the circuit is then by way of wire B, clamp O, to lamp, and from it by way of clamp 0, contact D, switch E, contact D, to wire B.
The inclination of the jaws d of the contactpoints insures perfect electrical contact at all times between them and the switch as the impinging surfaces of all of said parts wear.
The switch E being an elongated block, and both its ends e 6 simultaneously making and breaking connections with the contacts D D in different planes or on different or opposite sides of the same, little or no sparking of the current occurs at the time of forming and severing the contact. Consequently the switch and contacts do not rapidly deteriorate or wear away, as has heretofore been the case with the switches in use.
The switch E may be turned either to the right or left, and, if desired, be provided with suitable stop-pins.
' WVhat I claim is- 1. A switch for electric incandescent lamps, comprising a holder or casing, spring-clamps G O, rotating block E, and contact-points D D, each of which is composed of two jaws, d, and one of which is insulated and separate from said clamps, substantially as shown and described.
2. A switch for electric lamps, composed of two tubular clamps insulated from one another, a rotary switch block, and contactpoints, one of which is insulated from said clamps and the other connected to one of the clamps, substantially as shown and described.
3. A switch for electric incandescent lamps, composed of two split or doubled jaw contact-points, a switch-block: rotating between the jaws of the contact points, and metal clamps, one of which is insulated. from the contact-points and the other connected to one of said contacts, substantially as shown and described.
4. In a switch for electric incandescent lamps, the contact-points D D, composed of I00 split or double jaws which incline toward In testimony whereof I affix my signature each other at their outer ends, substantially in presence of two witnesses. as shown and described.
5. The combination of case or holder A, CRAIG ARNOLD- 5 clamps O O, contact-points D D, composed of Witnesses:
jaws d, rotary switch E, and wires B B, sub- S. J. VAN STAVOREN,
stantially as shown and described. CHAS. F. VAN HORN.
