UNITED STATES YArmar CHARLES G. PERKINS, OF HARTFORD, CONNECTICUT.
ELECTRIC LAMP AND SOCKET.
SPECIFICATION forming part of Letters Patent No. 360,244, dated March 29, 1887.
Application tiled October 11, 1886.
To @ZZ whom it may concern:
Be it known that I, CHARLES G. PERKINS, ofthe city and county of Hartford, Connecticut, have invented certain new and useful 1mprovemeuts in Electric Lamps and Sockets, which are described in the following specification, and illustrated by the accompanying drawings.
This invention relates to incandescent or glow lamps, so called, and to switches and switchsockets appartenant thereto.
The object of the invention is to produce a multiple-carbon lamp and appurtenant switch and socket, which are certain and convenient in operation and manipulation.
The best modein which I have contemplated the application of my invention is illustrated in said drawings, in which- Figure 1 is a side View of my improved lamp, socket, and switch, the casing of the socket being removed. Fig. 2 is a perspective View of said casing. Fig. 3 is a top View of said switch and socket, said casing being removed. Fig. 4 is a bottom view of said lamp.
In these views, the numeral 1 denotes the translucent exhausted globe of the lamp, while 2 and 3 are two independent carbons which are inclosed therein. These carbons are electrically continuous with two pairs of platinum strips, numbered 4 and 5, respectively, which are sealed in globe 1 in the usual manner. The neck of said globe is provided with an external cylindrical metallic casing, 6, which projects beyond said neck, and contains a thick annular disk of insulating material, 7. One end of casing 6 hugs said neck, and the other end of the same hugs disk 7. This casing is provided with two pins, 8, which project radially therefrom. The exposed side of disk 7 is provided with two pairs of nibs or pins, 9 and 10, which are formed of electrically-conductive material, and project a short distance from disk 7, as shown in Fig. 1. Said pairs of pins 9 and 10 are respectively connected with said pairs of platinum strips 4 and 5 by two pairs, 11 and 12, of copper wires, which are terminally soldered to said strips and pins, and pass through the open middle of said annular disk 7 The numeral 13 denotes the baseplate of the switchfsocket. This plate is an annular disk,
of bonzalete or other insulating material,
Serial No. 215.866. (No model.)
mounted in a brass socket, 14. This socket has a projecting hollow neck, 15, whose internal cavity is continuous with the central perforation through the annular disk 13, and is threaded as a female screw. A brass arbor, 16, provided with iinger-piece 17, is journalcd in a standard, 1S, which rises from disk 13. Thisl arbor carries a loose contact-block, 19, which is of the general form of a quadrangular prism, having, however, each olx its several faces a littlc inclined and prolonged, after the manner ot' a quadruple cam or a ratchet with four teeth. Two opposite faces ot' this block and the two ends ofthe same are sheathed withathin strip of copper, 20. On arbor 16, between standard 16 and block 19, is a iiXed collar, 21, which is provided with an engagement-piu, 22, projecting toward block 19. From this block another engagement-pin, 23, projects in the opposite direction. On arbor 16, between collar 2L and block 19, is a shortloose flat spiral or annular spring, 24. Standard 18 has a foot extending upon plate 13 to screw 25, which may be termed the positive terminal77 of the switch. Two hollow cylindrical standards, 26 and 27, rise from plate 13 upon opposite sides of block 19. The foot of standard 26 extends upon plate 13 to screw 2S,which is the negative terminal ofthe switch. The foot of standard 27 reaches up from plate 13 in the form of a contact-spring, 29, which is adapted to press upon block 19. Standards 26 and 27 are provided with spring'seated contact- rods 30 and 31, respectively, and these are provided with fixed terminal stops or collars 32 and 33, respectively.
The brass casing shown in Fig. 2 is of general cylindrical form, and, in conjunction with plate 13, forms a switch-socket The longer end of said casing lits snugly about plate 13, and is held in position by screws 34. Slot 37 is for the accommodation of arbor 16. smaller end of said easing is adapted to t closely upon casing 6, and is provided with two pairs of hook-shaped slots, 35 and 36, for the accommodation of pins 8.
Such being the construction ofmy invention, its operation is as follows: The switch-socket is applied to the lamp by slipping the casing of Fig. 2 upon casing 6 in such a position that pins 8 enter slots 35, or in such a position that pins 8 enter slots 36, and said casings are The I IOO turned relatively to each other by hand, so as to allow pins 8 to enter the hooked portion of such slots. W'hile said casings are being so turned the heads 32 and 33 brush against pins 9, or against pins 10, as the case may be, until one pair of said pins 9 or 10 is brought to a middle position of Contact with heads 32 and 33. The springs in standards 27 then acting upon the lamp through said pins 9 or 10, as the case may be, force pins 8 into the hooked portion of slots 35 or 36,` as the case may be, and so the socket and the lamp are held to each other by a double spring-catch acting through the electrical contacts between them. In this manner the lamp and socket may be applied to each other in such relative positions that terminals 25 and 28 shall, for the time being, constitute the terminals of carbon 2, as illustrated in Fig. 1, or in such positions that terminals 25 and 28 shall, for the time being, constitute the terminals of carbon 3.
I claim as my invention- 1. In an electric lamp, a translucent globe containingv two separate carbons, an insulating-disk which is provided with two pairs of pins or projecting pole-pieces, and a metallic casing which is fitted about the periphery of said disk and the neck of said globe, in combination with four wires or other conductors which pass through a hole in the middle oi' "said disk and connect each of said carbons with `one pair of said pole-pieces, substantially as and for the purpose specied.
2. In combination with the globe of an electric glow-lamp, an annular insulating-disk which is fastened to the neck of said globe by a cylindrical casing and is provided with two pairs of projecting contact points or polepieces which are connected with the carbons of said lamp by means of conductors which pass through the central aperture of said au# s vided with a pair of vprojecting pins, in eombination with asWitch-socket which is provided with two pairs of hook-shaped slots adapted to engage said pairs of pins successively, and with a pair of spring-seated contacts adapted to press upon said pairs of contact-points successively, and thereby to maintain the engagement of said pins with each of said pairs of slots in succession, as may be necessary for the successive use of said cai-bons, substantially as and for the purpose specied.
In testimony whereof I hereunto set my hand in the presence of two witnesses.
