Specification of Letters ratent.

Application filed January 19, 1916. Serial No.. 72,881.

To all 'whom t may concern:

Be it known that l, ERNEST ALSGHULER,

'a citizen of the United States of America,

l cap and sleeve engaged thereby to prevent Short circuiting between said cap and the circuit-closer vfor the lamp should the deM vice come in contact with any conducting element 'which' touches both the cap and cir cuit-closer.

This device is designed especially for that class of'pocket flashlights, the reflector of which is part of the circuit for the lamp carried thereby.

Other features of improvement will hereinafter appear.

I will now-proceed to describe my invention in-detaih the essential features of which will be summarized in the appended claims, reference being had to'the accompanying drawing, forming part hereof, wherein:

F igure' 1 is a sectional view, partly iii elevation, of a pocket flashlight embodying my improvements; Fig. 2 is a detail sectional side View, enlarged, of the movably connected conducting strips; Fig. 3 is a fragmentary face view thereof; Fig. 4 is a side elevation of a portion of' a flashlight showing another form of my invention; and Fig. 5 is a sectional-planview, of a portion of' the reflector and Contact carried thereby, the section lbeing taken on a line 5--5 in Fig. 4. In the drawing, the casing of a pocket vflashlight is indicated' by l, the said casing being-of insulatin, imiterial, Such as fiber and containing a battery 2. Each end of the casingll is 'providedwvith a threaded sleeve,,the Vlower sleeve 3 being connected to the `conductor/l which comprises a plurality ofslidably connected metallic strips 5 and (3, the lower strip 5 vbeing,r connected to the lower cap 3. The upper cap 7 engages and supports a metal cap 8 which holds the lens 9 in position1 as well'as the reflector,

10 and lamp 11 carried thereby, the said lamp being; screwed .into a socket 12 in the reflector 10.

As can be seen, the sleeve 7 is positioned below the upper or contiguous edge 13 'of the casing 1, that is to say, the edge 11 of the sleeve 7 is below the edge 13 of the casing; this is 'for the purpose of keepingr the sleeve 'i' and reflector 10 out of'contact one with the other, so that current cannot be conveyed from the reflector by direct contact or through any other conducting element, for the reason that vthe glass lens insulates the reflector 10 from the cap S which is carried by the said sleeve i'. The flange 15 of the reflector 10 does not overlap the casing 1, but is smaller in. diameter than the casing 1.

Current for the lamp is conveyed thereto `from the battery by the conducting strips 5 and through the medium of a slidable button 16 secured to the strip 6.

As can be geen in Figs. 2 and 3, the strips and 6 are slidably connected at 17 by a rivet and slot connection; hence when the button 1G is moved, the strip 6 will slide upon the strip 5. To close the circuit for the lamp 11 the button 16 Iwill be moved toward the end of the casing which carries the lamp` until the free end of the strip 6 touches the reflector 10, after which the lamp will glow.

lfroin the foregoing,y description, it will be apparent that a short circuit between the button 1G and cap 8 cannot be eilected, becausel the reflector as well as all other conducting elements are insulated :from the said cap 8.

ln the form illustrated iiilig. 4, the reflector 181s made of' insulating material, but carries a metallic lainp socket 19, havllatented June i3, 19156.

ing an annular flange 2() which rests in contactwith the conducting; strip 21, which may be movable as in the forni illustrated `iii Fig. 1, or fixed, as in the ordinary pocket flashlights.

The reflector 18 can be made of glass, porcelain, or any other suitable refleet-ingrr substance other than metal. The lamp-socket 19 with its flange can be secured to the reflector by any suitable means, such as byvcementiiiir, by plaster-ofaris, riveting;r or otherwise. rlhe reflector 18 carries a flange which rests upon the casing` A cap 24, engaging a sleeve 25, holds'- the l 'fion Vith n @und
