Oct. 29, 1929. LUDWIG SOCKET FOR ELECTRIC LAMPS Filed Sept. 14. 1926 'Palettes-oct. 2e, 192e LOUIS LUDWIG, OF BROOKLYN, NEW 'YORK SOCKET FOR ELECTRIC LAMPS v v Application mea september 14, Isae. serial no. 135,303.
'This invention relates to a socket for electric lamps'and has for its'object the provislon of a compact socket containing a thery mostatic circuit controller so that by the use of this socket a blinking electric light can be used wherever current is available. Further objects and advantages of the invention will Y become apparent as the descriptionproceeds.
While a preferred embodiment of the invention has been disclosed for purposes of illustration, it should be understood that various changes maybe made in the structure without departing from the spirit and sco .of the invention as hereinafter set forth and claimed. w
In the drawings; 1 Fig. 1 is a horizontal section through a socket embodying the invention;
Eig. 2 is a cross section oni line v2 2 of F l; n
x 1g. 3 is a section on line 3-3 of Fig. 4;
Fig. 4 is an elevation of the thermostatic Referring more specifically. to the drawings,rthe socket comprises the tubular metal`- lic shell 10 the lower end of which is threaded as at 11 to -cooperate with a conventional socket, while the upper end is threaded at 124 to receive a lamp A partition disc 13 of insulating material extends across the middle of the shell, and forms the bottom, of the lamp-receiving socket. The thermostatic unit is supported on a base 14- of mica or other insulatingv material. The thermostatic arm 15 is of a well-known construction and is spaced from the base 14 by a metallic bushing 16, a screw bolt 17 holding the arm in place. The upper' end of the thermostatic arm carries the contact point 18 adapted for cooperation with the Contact n scriew 19 adjustably mounted on the basevll. The lower end of the tubular shell '1Q is i closed by a core 20 of insulating material through which is formed a tapered aperture 21. The lower end of the thermostatic unit v projects into the aperturev 21 and is held in thermostatic element is freely suspended in f an insulated position in such a manner that it cannot contact with the side walls of the:
shell. v y v y fI'he thermostatic arm is surrounded by a co1l'26 of ne wire in a well-known manner,
the lower end ofthe coil belng connected to pe screw bolt 17 and its upper end bein connected to contact screw 19. The side o shell 10 1s apertured as at 27 to permit circulation not glow. ,At the same time the heating of the coilcauses the thermostatic arm to bend until it makes contact with the screw 19. At this time the `current passes directly throu h the arml 15 and the lamp becomes illuminated while the coil cools and nally 'the arm 15` of air so that the thermostatic arm can cool'to.
breaks the contact and returns to the starting l position.
The structure set forth comprises a simple and inexpensive socket including a thermostatic circuit-breaking mechanism and is adapted to produce a blinking light heretopensive apparatus.
I claim v l A thermostatic circuit controller for inser tion in a conventional lamp socket and comprising a base of insulating material, a conductive binding post mounted at one end of `the base, a thermostat arm carried by said post and extending normally parallel to the wire and carrying a contact at its free end, a
'fore obtained by more complicated and exvbase,lsaid arm havinga. winding of resistance screw extending through the base in alinement with said contact, said screw being electrically connected to the resistance Wiring of the arm, and nuts on said screw on opposite sides of the base holding the screw in adjusted position, one of the nuts forming a binding nut for a lead Wire. A In testimony whereof I affix my signature.
LOUIS LUDWIG.
