EDWARD WESTON, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF NEW YORK, N. Y.

INCANDESCE NT ELECTRIC-LAMP HOLDER.

SPECIFICATION forming part of Letters Patent No. 268,330, dated November 28, 1882.

Application filed July 17, 1882. No model?) To all whom it may concern:

.Be it known that I, EDWARD WESTON, a subject of the Queen of Great Britain, residing in Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Incandescent Lamp Holders, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

The object of my present invention is to provide for the incandescent lamps as now commonly made a socket or holder from which the lamps may be readily and easily removed,

but by which under ordinary conditions they are securely held and maintained in the circuit,

and this I accomplish in the following manner:

' I turn out of wood, vulcanized fiber, or other insulating material, a cup or socket, and in the bottom ,I clamp approximately semicircular springs, leaving one end of each free, bending the free ends or tacking on them small pieces of metal, to form catches. These springs 1 connect in any desired manner with the conductors of an electric circuit.

In making the lamps I flatten-out the conducting-wires and bend them near their ends at right angles. If the wires are not sufficiently heavy or stiflt' they may be supplanted by strips formed especially for this purpose, and

0 having one end somewhat heavier than the other, or the ordinary wires may be thickened by metal coatings electro-deposited thereon,

or joined to short pieces of stouter wire in well-understood ways, either before or after being placed in the lamp-base. In any case they should be bent or fashioned in such manner that when the lamp-neck is inserted in the socket and turned the wires will slip under the free ends of the contact-sprin gs and be 40 there held by the indentations or catches in the same. This means of securing the lamp and maintaining good contact is obviously applicable to incandescent lamps generally, when a portion of the lamp, whether contracted to form a neck or not, is adapted to fit'in a socket.

In the drawings 1 have represented a lamp of ordinary construction and a socket combined therewith, the means of securing the two being that above described, Figure 1 representing a lamp and socket combined, the latter being shown in section, and Fig. 2 a plan view of the socket.

The letter A designates 'a lamp-globe, in this case having a contracted neck fitting in aninsulating socket or cup, B. The wires 0 O, forming the leading-in conductors of the lamp, are sealed in the base or support D. of the lamp, and their projecting ends bent over or hooked, as shown at c c. As stated above, the wires without thelamp-globeshould be of sufticient strength to hold the lamp, and for this purpose may be strengthened by the electrodeposition of copper.

In the bottom of the cup-shaped socketB are the flat springs E E, arc-shaped or semicircular in general conformation. They are secured to the socket by screws passing through their ends, and are connected with screw-posts F F, to which the wires of a circuit may be connected. 7o

Near the free ends of the springs E E are formed indentations or corrugations e e, or pieces of metal may be tacked onto the springs to subserve the same purpose, as will be well understood.

To use a lamp with the socket it is only necessary to insert the neck in the cup and turn the lamp until the ends of the wires 0 O catch under the springs E E and slip into the corrugations or catches formed thereon. The lamp will by this means be securely held in place and a good electrical contact with its conductors insured.

The specific construction of the devices which I have now described may be varied to a considerable extent without departure from the invention, which comprehends generally spring-catches in the socket, with which the ends of the lamp-wires may be brought into engagement by the insertion in the socket of 0 that portion of the lamp through which the wires project and turning the lamp around until the ends of the wires are brought under the springs.

What I therefore claim is- 1. The com bination,with an electricincandescent lamp, having wires sealed in and projecting from the same and bent into hooks, of a socket containing spring-catches, with which the bent or hooked ends of the lamp-wires may 10o be caused to engage,substantially in the manner set forth.

2. The combination, with an electric lumpglobe having its metal conductors bent or booked at their outer ends, as described, in combination with a cup or socket containing arc-shaped springs or spring-catches, under which the bent ends of the Wires may be caused to engage by turning the lamp in the socket, as set forth.

3. The combination, with an incandescent lamp having its Wires strengthened and bent
