LEO :ll/LAYER, OF IOSTON, MASSACHUSETTS, ASSGNOR TO HENRY COLE COMPANY, OF BOSTON, MASSACHUSETTS.
SOCKET FOR ELECTRC LAMPS.
Application filed October 17, 1925. Serial No. 63,097.
This invention relates to sockets for electric lamps and more particularly to sockets for use in spot lights and domes for automobiles.
It is an object ofthe invention to simplify sockets of this class by a reduction in the number of parts used to thereby correspondingly reduce the cost.
It is also an object of the invention to produce a socket wherein the wire terminal plug is revoluble, and has at one end thereof contacts which coact with the lamp base for the control of the light, thus dispensing with intermediate plugs or contact carriers which have heretofore increased the cost and complication of the sockets.
Other objects of the invention will be fully' understood from a description of the drawings and the claim hereinafter given.
f the drawings: Y
Figure 1 represents a longitudinal section through a socket, some of the parts being shown in elevation.
Figure 2 is a section on the line 2-3 Figure 1 looking in the direction of the arrow marked 2.
Figure 3 is a section on'the line 2 3 looking in the direction of the arrow marked 3.
Like characters represent like parts throughout the several figures of the drawings.
tteferring to the drawings:
The drawings herewith illustrate a simple form of lamp socket embodying the invention which might be used in connection with a spot light, a portion of the reflector being shown by dotted lines at 10.
A tube 11 fast to the spot light proper in any usual or suitable manner has at one end thereof two bayonet joints 12. one of which is indicatedv by dotted lines Figure 1 of the drawings, and at its other end has revolubly mounted therein a wire terminal plug 13.
The lamp let is provided with laterally ez;- tended pins 15 to engage the oints 12 in well known manner.
The plug 13 has laterally extended pins 16. one of Awhich is indicated by dotted lines, to engage slots 17 in the tube 11 to thereby control the rotative movement of the plug 13.
The lamp base 18 is provided with two electric terminals 19 and 2O arranged to form electrical connection with two yieldingly mounted contacts 21 and 22 carried by the plug 13 in cylindrical members 23 and 24 which also receive the wires 25 and 26.
The terminal plug 13 of insulating material, is provided with screw threads 27 to receive the hand piece 28, also of insulating material, which is bored at 29 to loosely rel ceive the tube 11.
The hand piece 23 will be quite iirmly screwed onto the threads 2T with the end of the plug 13 abutting the shoulder 30 to thereby increase the frictional contact so that the hand piece 28 may be freely turned to rotate the plug 13 to control the lamp without loosening it. I
F rom the foregoing it will be readily seen that the socket consists of but three members, viz: the tube 11, plug 13 and hand piece 28.
When a lamp is in place in the socket, the
contact plungers 21 and 22 are held in close contactwith the base 18 when the light is out, or in contact with the terminals 19 and 2O when the light is on, by the action of the springs 35 and 36 which are compressed when the lamp is inserted in the socket.
The plug 13 which is freely revoluble in the tube 11 might have a tendency to rattle but for the fact that the said springs 35 and 36 also function to hold the pins 16 closely against the sides 37 of the slots 17, thus retaining the plug in a given position until such time as it is to be rotated by the hand piece 28.
Having described the invention I claim:
A lamp socket comprising a tubular member arranged to receive a lamp in one end thereof and a wire terminal plug in the other end; a wire terminal plug permanently assembled with said tubular member but revoluble therein and having an end extending bevond said tubular member and having yieldingly mounted electrical contact plungers at the other end* said Contact plungers being arranged to at times Contact with electrical terminals of said lamp; and means to revolve said terminal-plug.
