4 Claims.
The present invention relates to an incandescent lamp assembly and has as its prime object maximum saving of metals required in the assembly.
To this end applicant has designed a lamp base for use in a socket of the Edison type, which requires but a small percentage of the metal ordinarily employed in a base of this character.4
In the accompanying drawing Fig. 1 is a plan view of a lamp assembly embodying. the invention;
Fig. 2 is a side elevatio of the same partly in section along line 2 2 of Fig. 1;
Fig. 3 is an enlarged plan view of the base portion only with a detail partly broken away; and
Fig. 4 is a fragmentary view showing alternative details of the assembly.
Referring to the drawing in detail, the lamp assembly comprises the usual sealed envelope II, having lead-in wires I2 and. I3 projecting therefrom for connection with terminals adapted to with the shell and central contact button of an Edison type socket.
The base comprises a threaded shell I5 which may be conveniently molded of glass or other dielectric materials. The threads vII are of the usual pitch adapted to thread into an Edison type socket. Transverse of threads I6 is a groove I1 for accommodating a terminal strip I8 and with an aperture I9 through which one end of the terminal strip I8 may be projected and bent over to anchor one end of the strip to the base. The surrounding space is then preferably luted with cement 22. An apertured boss 20 is also an in" for an apertured disc 2| of conventional form usually employed as the central terminal of the assembly. ,Y
The interior of base I5 telescopes over and is attached to the base of envelope I I with cement 22 interposed between the envelope and its free'end allowed to probase I5 opposite its groove I1. The terminal strip I8 at the end adjoining the Wire I2 attached thereto in any II and base I5 groovev I'I and is anchored at eachI end Where it passes through and under shell I5. As is clearly apparent from Fig. 2, strip I8 is normally positioned intermediate the root and crest of threads I8 is preferably made of phosphor bronze or some similar resilient metal and, accordingly, effects a very dependable electrical connection with-the shell terminal of the lamp socket. The wire I3 is threaded through the apertures in boss 20 and disc 2| and solder is applied to anchor it in place.
In Fig. 4 the base is provided with a cavity 24 into which the upper end of a terminal strip I8' is projected and anchored with the aid of cement 22. This form of structure affords a further saving in metal employed and a reduction in cost of manufacture of the base. Preferably terminal strips I8 and I8 are given a slight curvature as shownin Figs. 1 and 3 to prevent unnecessary friction between the edges of the strip and the socket shell threads while the base is being threaded into or out of a socket.
From the foregoing it will at once be appreciated that the terminal strip I8 as used in place of the usually employed threaded metal shell effects a very material saving in metal without sacriiice of any of the dependable qualities of the metal shell form of structure. f
Although in the foregoing there has been shown and described the preferred embodiment of the invention, it is to be understood that minor changes in details of construction may be resorted to without departing from the spirit and scope of the invention as claimed.
I claim:
l. In an incandescent lamp assembly, an envelope, a lamp base attached to said envelope composed of a threaded shell of'dielectric material, and a strip of resilient conductive material extending transverse to the shell threads and electrically connected to a conducting element within said envelope.
2. In an incandescent electric lamp, a lamp envelope, a base of dielectric material having threads formed on the exterior thereof for threading into a light socket, and e, narrow band of metal arranged adjacent to but transverse of the threads for establishing electrical connections between the interior of the envelope and the shell terminal of a lamp socket into which the base is adapted to be threaded.
3. In a lamp assembly, a sealed envelope having `protruding wires for conducting electrical current into the interior of the envelope, a glass base attached to the end oi' the envelope from which the wires protrude; said base having threads for threading thesame into an Edison type velectric lamp socket, said base having a channel transverse of its threads for accommodating a metal terminal for contact with the shell of a socket and having an aperture for accommodating a button for electrical contact with the l socket base, a. metal terminal in said channel having one end attached to one of the protruding wires, and a. conducting button arranged over the base aperture and attached to the other of the' surface adapted to be threaded into a lamp socket,
10 socket.
said base having a longitudinal groove running transverse of said threads and of greater depth than the root diameter thereof, a resilient electrical conductor connected to said base at either end of said groove and normally occupying a position in said groove intermediate the root and the crest of said thread, said conductor being displaceable into said groove ush with the root of said thread when the base is screwed into a lamp HARRY RAY ICIEI-IL.
