IBEBN'HABD BENEDICT, OF NEW YORK, N. Y., ASSIGNOB '10 BEACON ELECTRIC COMPANY, NEW YORK, N. I.
Specification of Letters Patent. Pate nted Aug. 18, 1914 Application filed September 80, 1913. Scriallo. 792,57L-
To all whom it may concern:
Be it known that I, BnnNnARn BENEmcT, citizen of. the United States of America, residing at New York, in the county of New York and State of New York, have invented certain, new and useful Improvements in Circuit-Closers, of which the following is a specification.
The present invention pertains to electric flash light lamps, and particularly to circuit closers or switches whereby the lamp may be lighted o'rextinguished.
The hitherto used structures have been found objectionable because the switch after a short time of use, becomes ineffective, as the parts wear off very quickly. p
The object of my invention is to provide a switch that will be more durable and simpler in construction. I
With this object in view, my invention consists in the construction, combination and arrangement of parts as hereinafter described and set forth in the claims.
To make my invention clear, I shall refer to 'the accompanying drawing, in which similar reference characters denote corresponding parts and in which Fi re 1 is a front elevation of my new switc as applied to the casing, which is shown broken away at its ends; Fig. 2 is a longitudinal section of the complete lamp taken on line 22 of Fig. 1; Fig. 3 is a partial longitudinal section taken at a right angle tothat of Fig.2, the ends of the lamp bein broken away; Fig. 4 is an enlarged partial section similar to that of Fig. 2;
and Fig. 5 is a rear view of the slide forming a part of the switch.
The lamp is composed, as usual, of a casing a of hard rubber or other insulating material, which'is open at both ends. In one of these open ends is fastened, by the usual threaded thimble b, the reflector b which carries the lam (not shown), and the other end through w 'ch the battery 0 is inserted, is closed by a removable ca d. As usual, one terminal of the lamp ma es contact with one pole of the battery, while the other terminal of the lamp is electrically connected to the metal reflector b. Inside the casing two longitudinall extending metal strips e, f are provided, 0 which strip f, as usual, is in electric connection with the reflector b and is riveted to the casing. as at f, while the strip a is electrically. connected to the other pole of the battery located at the opposite end of the latter.
Secured to the outside of the casing a is a box-shaped metal frame 9 in which 15 ar-' ranged the spring slide forming part of the circuit closer or switch. Thus far the construction is well known.
My invention resides in an improvement in the circuit closer or switch whereby the latter is rendered more reliable and durable. The improvement consists in that the metal strip f at its free end is formed to a spring hook f which is adapted to project with its outwardly bulging surface into the box 9 through a narrow slot (1" in the casing a. The slide 72. is a flat metal piece having a rough outer surface and slidably bearing on the outer surface of the box or frame 9. The same is provided with a neck portion h that projects through a narrow slot 9' of the frame 9 and carries inside the lattera spring plate 71 suitably fastened to said neck. This spring plate at its upper end is also formed to a spring hook i which with its bulging surface is directed toward the casing a and is adapted to normally bear on the latter as at a.
The metal strip e is conductively connected to the metal box or frame g, as by a rivet e. When the slide it is moved from its inoperative or circuit openin position into the circuit closing position, tie spring part operativeness of the latter. 1
In order that the slide may be held in the circuit opening position when the lamp is not in use and that the life of the battery may thus be lengthened, I provide an automatically working locking means for the slide.-
In the present embodiment of my inven-- tion this locking means consists of a rounded projection gr extending from the inner sur ace of the frame or box 9 and adapted to engage acorrespondingly shaped depres sion z' in the plate 2' when the slide is moved into inoperative position.
Since various modifications may be made in the structure without deviating from the spirit of my invention, I do not wish to restrict niyself to the. details described and shown;
What I claim and desire to secure by Letters Patent is I 3 1. In a circuit closer, a casing having a circumferential aperture, a conductor strip in said casing the free end of which is resilient and formed to a part bulging outwardly through said aperture and a second conductor consisting of a slidable resilient member outside of said casing and having a part bulging" inwardly, the two bulging partsloeing adapted to constantly project into oneanothers path and to close the circuit when the sliding member is moved into circuit closing position.
2. in a circuit closer, a casing having a circumferential aperture, a box fastened to the exterior of said casing over said aperture, a conductor consisting of a fiat slide lnovably guided in said box and a spring plate carried by said slide and having a part bulging toward said casing, and a sec- 0nd conductor consisting of a strip having a bulging part projecting through said aperture into the said box, said two spring parts beini adapted to constantly project into one anot ers path and to come H1130 contact with one another when the sllde' is moved into circuit closing positron.
3. In a circuit closer, a casing having a circumferential aperture, a box fastened to the exterior of said casing over said aperture, a conductor consisting of a flat slide vmovably guided in said box and'a spring plate carried by said slide and having a part bulging toward said casing, a second conductor consisting of a stri bulging part projecting throng ture into the said box, said two spring parts being adapted to constantly project into one anothers path and to come into contact having a.- sald aper-= With one another when the slide is moved
