To all whom t may concern.' f

Be -it known that I, 'ANKER S. LYHNii, a citizen of the United States, residing at Bridgeport, county Connecticut, have invented an Improvement in' Pocket Flash Lights, of which the followingjs alspecification.

he object of the present inventionis to provide a pocket flash light of simple structure, practical design and convenient shape which will be cheap to'manufacture and reliable and eilicient in use.

With the above and other objects in view, the invention comprises the construction and arrangement of parts as now to be fully described a and hereinafter specifically claimed.

In the accompanying drawing forming a p part of this specification,

lin two parts, denoted by 11 and 12, which are Fig. 1 is a perspective View of a pocket flash light embodying the features of the invention;

Fi 2 is a lon tudinal, sectional view-of the iigash light ofig. 1 and Fig. 3 is a partial longitudinal section of a modified form of' the invention. i

The novel fiash light of this invention is composed of a few simply-constructed parts. The cylindrical casin which is adapted to receive a battery 10, t e cover of which is of course of insulating material, is constructed detachably connected to each other, part 12 being screwed into part 11 as indicated at 13.

Part 11 of the casing is adapted to carry a bulb 14 and for this purpose is curved backwardly` upon itself to provide an internally threaded neck 15 to receive the screw shell 16 of the bulb, and a properly shaped ortion 17 to act as a reflector. As shown in ig.

2, part 12 of the casing is adapted to carrya ring shaped insulating disk 18, and for this purpose is provided with inwardly extending beads 19 which insure the .position of the disk. The disk is provided with a central aperture 20 which is adapted to receive one end of a push button 21 the opposite end of which extends through an opening 22 in the outer end of part 12. The push button is provided with a shoulder 23 and has thereon a compression spring 24 which is located between the shoulder and the disk, the spring normally holding the shoulder against'the outer end of part 12. As shown in Fig. 3, part 12 of the casing is provided with a single bead 19 and is adaptedA to carry an inlpeoieatlon ot Letten Intent.

of Fairfield,` State of' sulating button 29 which extends between the bead and the outer end of part 12 as clearly disclosed. The insulating button is provided with a central aperture 2O which is enlarged to .form a cavity 30 for the compression spring, the lower end of the spring resting against the circumferential shoulder, denoted by 31, at the bottom of the cavit The push. button of the modified form isi entical with the push lbutton hereinbefore described and functions in precisely the same manner. A clip 25, attached to part 12 as indicated at 26, provides means whereby the Hash light may be frictionally held in a pocket, as will be understood As'shown, 27 denotes the negative pole and 28 the Positive pole of a battery of ordinary or pre erred construction. As will be clear from Figs. 2 and 3, the relative lengths of the casing and battery are such that when the battery has been positioned in one of the parts of the casin and the other part has been screwed in, t e center contact of the bulb rests against one of the poles of the battery,` while the other pole is positioned against the insulating disk or insulating button, as the case ma be, and in alinement with the 'aperture therein. The battery is thuslocated in the casing. Also, the push button is made of sulicient length to extend, when depressed, the entire ,distance between pole 28 and the battery and the outer end of part 12 and project slightly beyond the cas- It will be apparent that when the push button is in its normal position, as disclosed in Figs. 2 and 3, there is no electric connection between thepoles of the battery. When now the push button is depressed so that its inner end engages pole 28 of the battery, a circuit is completed and the bulb is conse uently lighted. The electric circuit, it will evident, extends from a pole of the battery to the 'center contactvof the bulb, through the bulb, through the screw shell thereof, through the casing, by reason of its contact with the screw shell, through the push button, by reason of its contact with the casing at openingv?, and to the other pole o f the battery. en pressure has been removed from the push button, it will be returned to normal position b the compression spring.

By arranging t e push button in an end of thecasing I rovide an article of the present character w ich is especially suitable for Patented Mar. '1, 1922. application nien my 1a, im: mm n. man
