LIGHTING-FIXTURE.

Specification of Letters Patent.

Applieatlia filed May 24, 1915. Serial No. 30,054.

To all whom it may concern:

lie it known that I, Auous'r Ilooonenr, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented new and useful Improvements in Lighting-Fixtures, of which the following is as ccification.

his invention relates to electric lighting fixtures, and it is the primary object of the invention to provide means to carry a lamp socket or sockets and having an electric connection plug, common to all the sockets, whereby to support the socket or sockets and the socket c arrying means by the plug from a connection in circuit with the source of current, and said plug being adapted to be connected to.

.and disconnected from a connection in cir:

cnit with the source of current as a unitwitll the socket or sockets and the socket and plug carryin means.

Anot ier object of the invention is to providea fixture fora. portable electric lamp stand whereby the stand may be adapted to carry a single lampor a plurality of lamps.

In the drawing accomlpanying and forming a part of 121118 speci cation Figure 1 is 1 side elevation of a portable electric lamp :tand or fixture illustrating in full lines an mbodiment of In invention ap lied thereto, .nd showing in ottcd lines a ampor bulb arried thereby in the ordinary use of the ame; and

Fig. 2- is an enlarged side elevation of my nproved fixture, said view being partly in action to illustrate the manner electriilly connecting the sockets to the plug and N3 connection of the socket carrying means i the plug, and showing the plug connected and supported by a connection in circuit ith the source of current.

Similar characters of reference designate to arts throughout the diflerent views of e rowing.

In Fig. 1 of the drawing I have shown an \bodiment of my invention in connection th a portable electric lamp stand comprisa base 3 having a stem or standard 4 to ich is secured a lamp carrying socket 5. this type of lamp stand as now conacted it is so constituted as to carry a le lamp socket to which a lamp or bulb own in dotted lines, may be connected. 0 adapt such a lamp stand so that two core lamps or bulbs may be carried thereelectrically connected with and "disconnectedfrom a socket by that any bore and are connected by and without changing the electrical installation or the structure of the stand itself, I provide a series of arms 7, shown in the resent instance as crably tubular, secured to and extending from an electric connection plug, shown in a encral way at 8 in Fig. 1. a

ecured to each of said arms, preferably the extremities thereof, is a socket 9. The plug 8 has positive and negative contacts-as usual and is common to all ofthe sockets that is, the lamp sockets are connected in circuit with said plug by current conductors 10 and 11 carried and con- 70 cealed by the arms 7.

In Fig. 2 I have shown an embodiment of my invention in connection with a fixture, such as a socket 12, secured in permanent position as to a wall or carried by a cured in permanent position, and in direct. circuit with the source of current. I

-I have shown my invention in connection with a plug adapted to be con' ected to and .nali'movenjent, although it will beo vious uitable connection plug may be utilized, In the present, instance the plug consists'of a block of insulating materia 13 havinga contact 14' centrally tocontact with the usual. contact 15 in the socket, a longitudinal bore 16 in said plug comminiicatin with a recess adjacent to contact 14. no conductor of each of the conductors 10 and 11 to the contact 1A. The other contact of the plug consists of a member 17 in the nature of a shouldered plunger or ball movably mounted in a transverse ingly forced out through an opening in an abutment 19, in the form of a washer or eyelet in one end of said bore by a spring 20, said s ring being retained in the bore by a meta 21 and in circuit with a member 17 through the spring], said plate havin a binding 0st 22. he plate and bimfing post are ocated in a longitudinal recess 23 in ,the side of the binding post the at or conductor or com ductors 10 and 11 is connected. The yielding contact 17 is adapted to engage with the usual screw threaded contact shell in the socket to retain the plug therein. A 110 cap 24 is removably connected as by a screw, to the reduced end of the block, said Patented Mar. 5, 1918.
