Patented Aug. 13, 1935 a gases The invention relates to electric lightrsockets and :the- "socket according to the present llnverie tion is especially adaptedto baused in connection with narrow. reflectors such as are commonly usedonrading'lamps and the like.

The object of the invention is to provide a socket which consists of two parts hingedly connected with each other so, that the one part may be fastened relatively, stationary and permanently inside the reflector while the other portion which really'contains the socket proper, may be the socket proper is in working position, that is,

when it is located inside the reflector.

A still further object of the invention 'isto provide a socket for electric lamps consisting of two parts hingedly connected with each other and having means for urging said two parts out of working position after the electric contacts, with which the two parts are provided and which cooperate to close the circuit in which the socket is arranged, have been'disengaged from each other.

Other objects of the invention not specifically mentioned will be easily ascertained and understood from the following description in connection with the accompanying drawing forming a part thereof. It is however to be understood.

that the invention is not to be limited or restricted to the exact formation and construction shown in. the drawing and described in the specification, but that said invention is only to be limited by the scope of the claims appended hereto.

d In the drawing illustrating a preferred embodiment of the invention:

Fig. 1 is a side view of a. socket according to the present invention, the two parts being shown in a position, in which the contacts electrically connecting said two parts with each other are closed.

Fig. 2 is an end view of Fig. l and Fig. 3 is a sectional view taken on line13-3 in Fig. 2, the two parts of the socket being shown in a position, in which the contacts electrically connecting said two parts are open.

Fig. 4 and Fig. 5 are end view and top view rethe present invention.

. The socket according to the present invention has a body consisting of a main portion 6, in which puma 1 y i I sesame i J iuji wentaloicrt, arid saga iiirsiiaem, f f p f thesocket proper is arranged. Inthe drawing a common" screw socket is shown consisting of a metal sleeve l hav ing threads formed in:its. inner circumference 'I'his metal 'wall is electrically connectedwitha contact plate 8, the' connection being made in, any suitableway as shown at !a in Fig; 2. On the bottom of the socket a spring contact 9 is provided, which in turn is electrically connected with a contact plate I!) as shown in 'Fig. 3. In the main portion 6 a second portion II is pivotally attached by. means of ahinge l2. This portion H is adapted to befastened in a y desired manner relatively, stationary and permanently to any desired supports. On the free end of said second portion H a pair of contact rods 13 of any suitable construction is provided and they are so arranged that each of said rods will contact with one of the plates 8 and I respectively, when the two socket portions 6 and I l are in the position shown in Fig. 1. From the foregoing it will be apparent that the rods [3 function as detent members andmaintain the member il in operative position with the member 6.

Preferably the endof the rods I3 extending somewhat beyond the portion II has a globular shape and the free ends of the plates 8 and H! are formed with respective hollows l3a so as to accommodate said globular parts of the contact rods. When the two portions 6 and Il are forced against each other the globular ends of the contact rods l3 will be forced into the hollows formed in the contact plates, so that the two contact portions will be held in working position through the engagement of the contact rods and contact plates. The plates 8 and) are resilient, readily permitting a flexing thereof, whereby the rods l3 may seat in the hollows.

A pair of binding posts I4 is provided in the second socket portion II and electrically connected with the contact rods [3.

The exact construction of the binding post shown in Figs. 4 and and indicated in the other figures of the drawing is the subject matter of Patent #1,795,627 issued March 10, 1931 and said binding posts are therefore not described in detail in this application. It is hereto to be noted, that binding post of any suitable construction may be used in connection with the present invention as long as they are adapted to be connected to and to hold electric wires or cables l5 and to be electrically connected with a plate I4 fastened to the second socket portion l l and contacting with the spring contact l3, so that an electric lamp, inserted in the socket 1, may be energized when the contact rods and contact plates are in working position.

By the use of a socket as described above the exchange of an electric lamp arranged in said socket will be facilitated in so far, as it is not necessary to disengage such lamp while it is arranged in the narrow confined space inside of a lamp reflector, but that it is possible to pivot the portion of the body containing the electric lamp into a position where said lamp extends outwardly of a reflector in which the lamp is being used. At the same time the connection between the electric circuit and the lamp is automatically broken when the lamp is pivoted into position for removal, so that it will be impossible to receive an electric shock while removing or exchanging a lamp.

Having described our invention and how the same is to be performed we claim as new and desire to secure by Letters Patent:

1. In a device of the class described a body portion, a socket for an electric lamp, a pair of contact plates, one of which is connectedwith saidisocket, a spring contact electrically connected with the second plate and arranged at the bottom of the socket but spaced therefrom, a second body portion, a hinge connecting said two body portions with each other, a pair of binding posts in said second body portion, a pair of contact rods electrically connected with said the other of which includes a spring contact 1 within the socket, each of the contact plates terminating exteriorly of the socket, a second body member hingedly connected with the first body member, a pair of binding posts in the second body member; a contact rod electrically connected with respective binding posts, the outer ends of the contact rods projecting slightly beyond the second body member, and the outer ends of thetcontactplates having hollows for reception of respective contact rods. 3
