INEENTOR. 'eayaflM/mleuv BY fF/Afkrmmvmi GEORGE A. SOEHNLEIN, OF BROOKLYN, NEW YORK.
PORTABLE nLl-zc'rmc LIGHT.
Specification Letters Patent.
Patented Aug. 14, 1917.
Application filed October 5, 1916. Serial N 123,821.
To all whom it may concern:
Be it known that I, Gnonon A. Sonrmrmm, a citizen of the United States, and a resident of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements 'in Portable Electric l' ights, of which the following is a specification.
This invention relates to portable electric lights, and particularly to the means by which the current from the batter is conduct-ed to the-lamp." ()ne of-the 0 ects of my invention is to provide a cheap, simple and cflicient' means by which any possibility of the short-(1i rcuiting of the battery may be )reventcd and by which a conducting,
pat1.- directto the'tcrminals of the lamp will be provided.
With these and other objects in view, my invention consists of certain novel features of construction, combination and arran ement of parts, as will be'more fully escribed and pointed Out in the appended claim. y
In the drawings, Figure 1 represents a partial longitudinal sectionofone type of flashlight which I have chosen for purposes of illustration, which figure shows one form of my invention.
-tery. 12 is the usual lens, 13 .the re ector,
14 the incandescent lamp and 15 theferrule,
. which, in the form illustrated, is screwed on the casing 10 to hold the lens 12'and the reflector 13 in place againsbthe outer edge of the casing 10.
i The reflector 13 is provided with an pening into which is placed a bushing 16 0 nonconducting material. The bushing 16 is provided with a ,flan'gc which projects on the inside of reflector 1 3 and preferably this bushing 16 is also internally threaded.- Into the opening in'the'bushing 16 extends, pref- .erably by suitable threads, a conductor 17,
which in the form illustrated, is a circular plate having upstanding edges 18, The prothrough rivets 23 with a sliding F1 2 is a plan o f the circular contactexterior of the battery 11 and the pole 21 thereof. It will be understood that in this type of lamp the battery 11 contacts either directly or indirectly with the'casinge 10, so that any conductor makin pout-act with the casing "10 and also with. tie conducting late 17 will-provide a circuit throu the amp when the pole 21 is in contact with the other terminal of the lamp. As one form of suitable switch for this purpose, I have illustrated a slidable member 22 connected thumb piece 24. The member 22 preferab y has an inwardly bent ortion 25 which, when the member 22 sli es upward, contacts with the upstanding members 18 of the plate 17. This upstanding rim of the plate 17 is preferably cut in a. number of places as shown best in Fig. 2,'so that this rim may be bent outward slightly in order to insure contact between it and the sliding member 22.
-It will be'seen that since the reflector 13 .1
is insulated entirely from the lamp, there is no possibility of short'circuiting the battery nor the accidental lighting of the lamp 14 by any metal contacting with the reflector and the casing 10. Moreover, by reason 01 the construction of th parts 16, 17 and 20, it will be obvious that the same may be readily assembled or disassembled, and that since the parts can be separately made and assembled by hand, the construction is not only efficient but extremely cheap, without any possibility of the reflector 13 coming in contact with either of the terminals of the lamp 14.
