Specificationv of Letters Patent.
Patented Dec. 26, 1916.
Application .led'December 26, 1913. Serial No. 808,664.
To all vwhom t may concern.'
Be it known that I, CLARENCE A. VETTER, a citizen of the United States. residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful improvements in Lamp- Sockets, of which the following is a specification.
My invention refers to improvements in the class of sockets for incandescent lamps.
It has for its object to provide a keyactu ated socket adapted to'operate for'making and breaking the vcurrent vby partial rotation of the actuating key' within' the base, the device being provided with co-acting spring-actuated elements, whereby the completion of the operation is effected to insure. a. quick make and break of the contact` or 'current establishing mechanism.
Thel invention, as constructed, and for the purpose of accomplishing such objects, consists generally of a base portion of insulating material having the usual terminal connections and the central and screw shell contact portions for engagement with ther lamp base: an intermittently operative actuating key and stem: a make-and-break circuit opening and closing device thereon having a lost motion connection with the key: a` fixedly attached spring-actuated throw device oii the stem: and a. lost motion connection between the key and the stem, as shall be. more fully hereinafter described.
Retcrring'now to thedrawings illustrating` one preferred form ofthe invention,.
Figure 1 is a vertical sectional view through the socket, indicated by the section line I. of Fig. Fig. 2 is a similar vertical sectional view at right ang-.les to Fig. l. indicated by the section line Il. ll. of Fig. 3. Fig. 3 is aplan view oi: the socket. Fig. at is a 'horizontal sectional view. taken on the line IV. IV. ot' Fig. l. Fig. 5 is a vertical sectional view through the insulating base portions. indicated by the line V. Y. -ot' Fig. 3. Fig. is a partial vertical sectional view. similar to Fig. 2. showing the switch open. Fig. 7 is a perspective detail vir-w ot the current establishing key-actuated conductor block. Fig. S is a similar view of the spring for the stem controlling block.
In the drawings. the insulating base of the socket is composed of two parts. fr and of porcelain or other suitable insulating material. fixedly connected in any vsuitable manner, as by screws c, the lower base member 71 having the screw shell 2 for receiving the base el' of the lamp D ofthe usual construction, and having the central contacting terminal portion d. Shell '2 is fixedly connected with base member b by screws 3, 8. to vone of which, by a. binding screw device 4, is connected the terminal of one of the main supply wires e. The other contact wire` fis connected by a binding screw device 5 with an upper spring. contact terminal 6, which is fixedly mounted within the upper portion of th socket, and to member a thereof, by screw 7. vAs shown, the inner central portion of meinbers a and 7) is hollowed out for clearance of these parts and of the other operating ele ivided with an actuating finger terminal 10. of suitable insulating material. inwardly from which extends the stud portion l1. em-
bracing the endof stem 8.- The ystud 11 is lprovided with transverse slots 12 at one or both sides. into which extend the terminal or terminals of a transverse pin or key 13. which likewise extends through or is iixedly connected with the stern S.
The-purpose of slot 1'2 is to permit the rotation of stem 8 by the` accelerating spring-actuated mechanism for completion of the throw ot the stem to effect quick make orvbreak ot' the contact mechanism. supplemental to the initial turning action by the terminal l() .and its stui'l l1. For the purpose oit' effecting such supplemental ac-4 cele'rated movement of stem S. and its conductor block. l provide a rectangular block 1l fixedly secured or mounted on the stem b v soldering or other suitable means. he ving opposite parallel faces which are normally embracml bctwecn. the inwardly pressing spring leaves l5, 15, of a resilient cievis. the base. 1G of which is ixedly secured to the lower insulating base member 7i by a hohling screw li' or other suitable device.
The conductor block 1S. oic suitable conducting material. as brass. is loosely mounted upon stein which passes tlirougi
