Specification of Letters Patent.
Patented ul 27, 1909.
Application filed December 14, 1907. Serial No. 406,528.
To all whomjit may concern:
Be it known that I, JAMES MCGAVIN, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Electric-Lamp Sockets, of which the following is a specification.
This invention relates to electric lamp sockets, the object of the invention being to provide a supplemental or auxiliary lamp socket which is applicable to the usual sockets of incandescent electric lamps, whereby the lamp and the reflector attached thereto may be adjusted to any desired angle with relation to the supporting wire or conductor, thereby making the lamp as a wholemuch more effective and salable 'without adding but a trifle to the original cost thereof.
With the above and other objects in view,
the nature of which will more fully appear as the description proceeds, the invention consistsin the novel construction, combination. and arrangement of parts as herein fully described, illustrated and claimed.
- In the accompanying drawings :Figure 1 is a side elevation partly in section of'an incandescent electric lamp, showing the improvement applied thereto. Fig. 2 is a detail vertical section through the socket of this invention.
Referring to the drawing 1 designates lfaving the ordinary socket 2 and having a reflector 3 connected therewith.
In carrying out the present invention, I
employ a device which is in the nature of a tumbling or universal joint embodying .ball and socket members 4 and 5, respectively, each of said members being preferably formed of thin sheet metal such as brass which may be stamped or pressed into the desired shape by means of suitable guides. The ball member 4 is in the form of a hollowsphere cutaway at one side as shown at 6 to admit of the necessary movement of the ball within the socket and also to provide an opening through which the supporting wire or conductor passes to the lamp as shown in Fig. 1. The ball member 4 is further provided with a cap flange 8 which embraces the usual socket or head 2 of the lamp and is secured thereto by means of a screw 9 or other suitable fastening device. 7
Theball socket member 5 is preferablythe lamp against such conductor.
latter in any position or at any angle to which the lamps may be adjusted as indicated in the drawings. r
At its upper end the socket member 5 is 'provided with an opening 11 through which the conductor 7 passes and adjacent to said opening the member 5 is'provided with oppositely projecting jaws 12 adapted to bear against the conductor and frictionally hold 7 A clamping collar 13 embraces the upper end of the socket member 5 and receives a clamplng screw 14 which engages one of the jaws 12 and presses the same toward the other jawso as to firmly clamp the conductor 7 between both jaws, thereby placingweight and straindirectly on the conductor and relieving the points of connection of said conductor to the electrodes or binding posts of the lamp.
By means of the construction above described, it will be seen that the lamp proper maybe turned to any desired. angle relatively to-the socket member 5 and the con- I ductor 7 as fully illustrated in the drawings, thus enabling the light .to be reflected and directed in any desired direction.
I claim An electric lamp socket comprising a lower ball member and an upper ball socket member having the upper portion thereof divided to form s ring aws, both members having openings or the conductor and Saul lower ball member having means for engaging and supporting the ordinary electrlc lamp, a clamping band encircling the spring jaws of the socket meinber, and a clamping screw carried by said'band and impinging 'against'one of said jaws.
In testimony whereof I aflix my signature,
in presence of two witnesses.
