Description

Feb. 21, 1933. 1 PQKRNEY 1,898,498
QUICK DETACHABLE LAMP Filed May l, 1931 nven for liomey Patented Feb. 2i, 193s PATENT OFFICE JOSEPH POXOBNEY, OF BALTIMORE, MARYLAND QUICK DETACHABLE LAMP Application led Hay 1, 1931.
This invention appertains to new and useful improvements in electrical incandescent lamps, and more particularly to a lamp of the quick detachable type. The principal object of this invention is to provide a lamp which can be quickly inserted and quickly removed from the conventional threaded types of lamp sockets.
During the course of the following specification and claim, other important objects and advantages of the invention will become apparent to the reader.
In the drawing Figure 1 represents-.a fragmentary side elevational view of the lamp.
Fig. 2 represents a fragmentary side ele vational view of the lamp showing the detente in a different position.
Fig. 3 -represents a fragmentary detailed sectional view of the lamp engaged in a socket.
Fig. 4:` represents a fragmentary detailed sectional view showing a modification of the invention engaged into al conventional socket.
Fig. 5 represents a fragmentary detailed sectional view taken substantially on the line 5-5 of Fig. 4.
Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 represents the shell of a conventional lamp socket which has been stamped to provide the threads 6. At the inner end of the socket 5 is the usual spring 7, with which the central contact 8 on the lamp base 9 engages.
To facilitate quick attachment and detachment of the lam with respect to this conventional type o socket a detent such as is generally referred to by numeral 10 is provided on the base 5 along with transversely ribbed plates 11. Y
This detent 10 is substituted for one of the plates 11 and consists of a leaf spring 1 2 secured at one end as at 13 to the outer end portion of the base 9. The spring 12 is offset outwardly as atl 14 adjacent the portion 13 and then extends along the side of the base 9 and for a short distance of the neck portion of the globe l15. Nv pim, if. Y
VKTins-latter portion of the spring 12 1s pro- Serial No. 534,380.
vided with a di-electric covering 16. A spring 17 is secured at one end to the base 9 opposed to the intermediate portion of the spring 12 and bears against the latter to normally maintain the latter in an offset urged position.
The outer side of this spring 12 is provided with the outwardl extending teeth 1S which engage with the t reads 6 of the socket 5 to maintain the base 9 of the lamp in the socket. 50
The spring action of the springs 12 and 17 also serves to maintain the ribs on the plates 11 engaged with the threads 6.
Fig. 4 shows a modification of the invention wherein the base 9 is provided with a 55 bracket 19, the major portion of which is spaced from the base 9 -while its end portions are secured to thebase. One end portion of the bracket 19 is bifurcated to pro- 21 protrudes. The end of the spring 21 within the bracket 19 is secured to the outer end of the bracket and this spring 21 is provided with a tooth 22 operative through an opening vide a space 20 through which the leaf spring 7 23 inthe bracket 19 to engage the teeth' 23 75 of the lamp socket 5.
The outer free end ofthe spring 21 is provided with a di-electric covering 24. Thus it can be seen, that by moving the di-electric plug of 'the spring 21 toward the bulb 15, the 30 tooth 22 is disengaged from the threads 23 so that the. lamp can be inserted into the" socket or removed therefrom.
Obviously, when the base 9 is inserted into the socket and the spring 21 released, the 35 departing from the spirit and scope of the invention as claimed hereinafter.
,f ffi'm electric lamp, a base for the lamp,
a leaf spring member secured at one end to the base and being diverged outwardly from the base at its remaining end, a. tooth on the member, a bracket for the spring having an opening therethrough, through which the 5 tooth is operative, said bracket serving as a stop to limit outward movement of the member.
In testimony whereof I affix my signature.
