INOANDESCENT-LAMP SOCKET.

Specification of Letters Patent. Patented Dec. 21, 1909.

7 Application filed December 11, 1908. Serial No. 467,012.

To all whom it may concern:

' Be it known that we, LE0 DORNER and Gnonor. H. NoR Uis'r, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented a new and useful Incandescent-Lamp Socket, of which the following is a specification. 1

This socket is designed for use in connection with chandeliers, and such other electrical appliances as may require it.

The objectof the present invention is to provide a socket'conslsting of separablescc tions which may be readily detached, and also to provide improved means for lockin the sections in assembled positions.

Theinvention also has for its object to provide a socketwhich is simple in structure, and which can be easily and cheaply manufactured.

In the accompanying drawings :Figure 1 is an elevation .of the socket: Fig. 2dis a vertical sectional view thereof: Figs. 3 to 5 are elevations of the three sections constitut-,

ing the socket, said sections beingshown detached.

Referring more particularly tothe drawings, the three sections comprising the socket are indicated at 5, G and 7, respectively, the

first mentioned one being the shell which receives the lamp. The section 7 is the cap throughwhich the wires enter, and the section 6 serves as a .connection'between said sections 5 and/L The section 6 is a ringwhich is attached to the cap 7 by a close-fittingrolled joint allowing it to turn. The cap has a flange 8 over the outside of which the ring fits. The end of the shell 5 is placed within the flange 8, and said end is nely ridged or corrugated as indicated at 9, andis engageable by inwardly projecting crimps 10 011 the-flange, whereby the shell is held at adjustment after it is turned to the desired point. Projectin from the edge of the ring 6 is a series of Tiooks 11, whichare'engageab'le with tongues 12 on the shell- 5. The shell is vslitted, and the ton es thus" formed are bent outwardly to stan a short distance away from the'outer surface of-the shell,in order that the hooks may be engaged therewith. The hooks are also bent slightly outwardly so that they may be brought in line with'the tongues.

The hooks are engaged over the tongues by thereon, which come together, thereby preventing endwise separation of the parts, and the/hooks cannot be disengaged from the tongues except by a tu'rnin movement of the shell or the ring/ One of tie hooks carries a spring tongue 14, having a small hole 15, which snaps' over a projection'or lug. 16 on the shell 5, when the hooks are engaged with the tongues as stated, whereby theshell and the ring are securely locked together.

The socket sections, when looked as herein described, will hold any ordinary weight without the sections becoming separated. No screws are used in fastening the sections together, therefore making it more economical in manufacturing them than the ordi nary socket now in use.

It will be of course understood that, in actual use, the socket will be lined with a suitable insulating material.

The slits forming the tongues 12 are angular shaped, as clearly shown in Fig. 3 of the drawings, whereby a stop is formed by the body of the shell at the inner end of the tongues, and the ring is thereby prevented from being turned too far. \Vhen the cap 7 is turned in place, the key of the socket can be placed in any desired position without movin the cap.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

- 1. An incandescent lamp socketcomprising a shell having outstanding locking tongues, and a ing, a 'cap removably connected to the shell, a ring rotatably mounted on the cap, hooks on the cap engageable with the aforesaid tongues, and a spring tongue on one of the hooks having an openend of the tongues, acap connected to the shell, and a' ring rotatably mounted on the cap, and having hooks engageable withthe aforesaid locking members.

3. An incandescent lamp socket eoinpris- In testimony that we claim the foregoing it) ing a shell having outstanding looking as our own, we have hereto affixed our signatongfiile's, and oorrugateld at one of 1ts e11ds,a tlll'OSill the presence of two witnesses. cap tting at one end t 1e corru ated ortion of the shell, and having crimfis eng a geable gig %B b w with the corrugations, a ring carried by the J J eap on the outside thereof, and rotatable Witnesses: thereon, and hooks onthe ring engageable ROBERT H. KANE, with the aforesaid tongues. MAY HAYS.
