Description

Feb. 13, 1934. FEATHER$TQ- 1,946,786
ELECTRIC LAMP SOCKET Filed May 18, 1951 'IITIVIENTOR: a. 5%-
A TTORNEY Patented Feb. 1934 UNITED STATES PATENT OFFICE This invention relates generally to electric lamp sockets and more particularly to a combination plug and outlet.
The main object of the invention is to provide a device of this kind which will allow the connection of the usual electric lamp or bulb with its threaded base to the conventional form of wall or socket outlet of the type adapted to receive the spaced blades or prongs of an attachment plug. To this end the invention comprises a socket for the reception of the bulb or lamp and extended blades or prongs for inser-' tion into the outlet.
Another object is to provide a device of this kind in a simple, inexpensive, efllcient and easily portable form.
With these and other objects in view the invention resides in the novel construction and arrangement of parts as hereinafter set forth and claimed, reference being had to the accompanying drawing wherein:
Figure 1 is a side elevation of the invention.
Figure 2 is a similar view taken at an angle of ninety degrees relative to the first.
Figure 3 is an end view looking at that end in which the lamp socket is provided.
Figure 4 is an enlarged longitudinal section through the invention.
Referring now more particularly to the drawing the body portion 1 of the invention is moulded in conventional manner of an insulating material such as Bakelite, hard rubber or the like and as shown is of circular cross section and tapered from its center to its ends though it is obvious that it may take any other form desired. A recess 2 is formed in one end of the body 1 and a threaded metallic socket 3 is seated in this recess, said socket being of conventional diameter and thread to receive the threaded base of the usual electric lamp or bulb (not shown). The inner end of the socket 3 has an inwardly extended annular lip or flange 4 and a circular plate or disk 5 of mica er 9 and a screw 10 is passed centrally through thediskfiandthreadedinthe attachingarm8 of the blade 7. Thus when the lamp is screwed intothesocket3theblades6and'1willmake connection to the base of the lamp .through the said socket and the screw 10. The screw 10 has a relatively large head 11 and passes through a washer 12 ensuring'a positive electrical connection to the center contact of'the lamps base. The screw 10 and the'biade 7 are V insulated from the socket 3 by the disk 5 as will be readily apparent. I
Inusethelampisthreadedinthe socket3 and the blades 8 and-7 arethen'inserted in thespaced slots in the wall outlet orconvenience plug (not shown). The lampis of course thus connected tothe source of currentand will be in places hitherto impossible and is of such small size that it may be readily carried from place to place or moved from outlet to outlet. Further uses and advantages of the invention While I have hereinset forth a certain preferred embodiment of my invention it is understood thatimayvaryfrom thesame in minor parting from the spirit of the invention and withicfixge scope of the appended claim.
In a device of the kind described, an elongated body portion tapered circumferentially from end and having a recasinoneend,athreadedmetallicsocket seatedinth'ereussandhavinganinwardly disk of insulation placed in the socket flange, rivets passed through the marthe disk and the flange, a prong exded lomitudinally through the body portion ha an angularly bent attaching arm at resting against the flange of the of the said rivets passing also said attaching arm of the prong, prong extended longitudinally through thebodyportioninparallelismwlththenrst mentioned prong and having an angularly bent arm at its inner and disposed inwardsocket flange and against the insulaand a contact screw threaded centralthe said disk into the attaching arm MARION FEATHE'RS'IUN. no
