$PEOIFICATION forming part of Letters Patent No, 725,133, dated April 14,, 1903.
Application filed February 3, 1902. Serial No. 92,244. (No model.)
To ctZZ whom it may concern:
Be it known that I, GUY H. PROOTOR, a citizen of the United States, residing at Somerville, in the county of Middlesex, State of Massachusetts, have invented a new and useful Improvement in Electric-Incandescent-Lamp Sockets, of which the following is a specification.
My invention consists in a new form of snap circuit-controller and ofa combination of this with two disks and with the circuit connections, shell, and other parts of such lamps.
Referring to the drawings, Figure 1 'is a view of the socket and shell. Fig. 2 is a top plan with disk C removed. Fig. 3 is a section on 3 3 of Fig. 2. Fig. 4 is a section on 4 4; of Fig. 2. Fig. 5 is a plan of the innersurface of disk C. Fig. 10 is'a section in part, showing a modification. Fig. 6,7, 8, 9, 11, and 12 are details of spring-plate, contact-piece, standard-support, and bottom of the shell, respectively.
Referring to said drawings, A is the shell, which differs from the usual shell in having a bottom part in place of a mere flange, a being a slot for contact L, and a a slot for a screw Z for holding the upper disk to standard E, as shown in Fig. 9.
B is the lower disk, formed with an opening Z) for depression d of spring-plate D, and C the upper disk.
D is the spring-plate, and d the depressed spring portion of said plate.
' E E are two supporting-standards, and e the circuit screw connection on standard E, and e e are lugs or projections on standard E.
F is the hub-handle, and G the shaft connected therewith, having a pin 9 thereon and also a collar g to hold said shaft in place against the stress of the spring H encircling the same. I is the circuit closing piece loosely mounted on said shaft and having one end of the spring H connected to it, the other end of said spring being connected to the shaft. This circuit-closing piece I has two bevels t' t' on opposite sides of the same, Fig. against which the pin or shoulder g on the shaft bears in rotating, while 2" t" are the circuit-closing tips of the piece I.
K is an insulating-plate, of mica or similar substance.
Asimpler modification of shaft, spring, and circuit-closing piece is shown in Figs. 1O, 11, and 12, in which the collar g is omitted and fiat spring H replaces spiral spring I-I, being attached to standard E by screw 2 and its free end always bearing against shoulders X X of circuit-closing piece I, and standard E replaces E, or, in other words, the standard is made without the lugs e of Fig. 8.
It will be seen that upon inserting the ordinary lamp connection will be made with its base and the center-spring connection L, which extends to binding-screw3 forone wire.
The other wire is attached at binding-screw c,
Fig. 2, to an arm, Fig. 4, on standard E. Thus the circuit when the current is turned on is through binding-screw e, arm 4., standard E, shaft G, tip 2" of contact-piece, spring-plate D, shell A to the screw-shell of the usual lamp, and through the lamp-filament to center contact L. The contact is made and broken between the tips of the contact-piece and the depressed portion 01 of the springplate D.
The operation of my apparatus will be plain from the drawings and the above de scription. Assuming the circuit to be broken between the depressed spring part d of the spring-plateD and the tips of the circuitclosing piece I, it will be seen that rotating the shaft G by the hub-handle F will cause the pin 9 upon the shaft to bear against one or the other bevels i upon the circuit-closing piece 1, thereby crowding the same against the stress of the springH out, so as to enable it to pass a lug or projection c upon the standard E, and thereupon to be snapped by the stress of the spring H, so as to bring one of the tips 2" of said circuit-closing piece into contact with the depressed spring portion cl of the spring-plate D, thereby establishing the circuit. A further quarter-rotation of said hub and handle will snap the circuitclosing piece I out of contact with said depressed spring portion d. If the simpler modification of Figs. 10, 11, and 12 be used, the only difierence will be that rotating shaft G will cause contact-piece I, Fig. 11, to snap from a horizontal into its vertical position, as shown in Fig. 10, against the stress of spring H, thus bringing a tip t" of the contact-piece into connection with the depressed portion d of the spring-plate D.- I
Having described my invention, what I claim is 1. An electric-incandescent-lamp socket composed of the following parts: a socketshell with bottom A, a lower disk B supporting said shell, an upper disk 0, a springplate D having a depressed spring portion (1, two supporting-standards E E, said standard E being provided with a circuit screw connection eand said standard Ebeing provided with lugs e e; a contact L with circuit screw connection 3, a handle connected with a shaft carrying a pin, adapted to move a circuit-closing piece, and a collar, a circuit-closing piece I formed with bevels ii and tips 1" 'i, a coiled spring H connecting said shaft and said circuit-closing piece, and an. insulating-piece K.
2. In an incandescent-lamp socket a snap circuit-controlling device composed of two standards E E, said standard E being provided with two lugs or projections e e, and said standard E being provided with a hearing for one circuit-connecting screw; a contact L with circuit screw connection 3, a hubhandle F, a shaft G, a pin 9 on said shaft and a collar g also thereonfa circuit-closing piece I loosely on said shaft and constructed with the opposite beveled portions thereoft' t' and with two contact-tips thereof 11'1", and a spring H connected to said circuit-closing piece I and said shaft-G; substantially as described and shown.
3. An incandescent-lamp socket composed a spring-plate, a second insulating-disk, two
standards connecting said disks, a handle, shaft and contact-piece on said shaft constituting a circuit-breaker supported by said standards, a spring-plate adapted to be supported upon the disk supporting the shell and in electrical connection with said shell and having a depressed portion adapted for make and break of the contact with said circuit-piece, a center contact supported on one of the insulating-disks; circuit screw connection on one of said standards and a second circuit screw connection upon said contact, and an insulator between said spring-plate and center contact, all substantially as described and shown.
4. In an incandescent-lamp socket, the combination of an insulating-disk, a second insulating-disk having an opening for permitting contact of a circuit-breaker with a contactspring, means for holding the two disks together, a revolving circuit-breaker supported between said disks, a contact-plate with a depressed portion and supported on the shellsupporting disk and said depression projecting through its opening; and a second contact-piece supported by one of said disks and bent over the center of the shell-supporting disk, and an insulator between said center contact-piece and said contact-plate, substantially as described.
In witness whereof I hereunto set my hand this 31st day of January, 1902.
