FLASH LIGHT.

Application filed July 25,

My invention relates to flashlights and particularly to the type commonly known as pocket flashlights.

An object of the invention is to provide a flashlight of the type described in which the sides thereof are free of all protuberances including the switch.

Another object is to provide a switch for the light, which is adapted to be actuated in a manner that will insure against the accidental closing thereof.

A further object is to provide a flashlight in which the construction readily lends itself to the inclusion of a receptacle for storing extra lamps.

The invention possesses other objects and features of advantage, some of wh ch, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within. the scope of my invention as set forth in the claims.

Referring to said drawings:

Figure lis a longitudinal sectional view of the flashlight.

Figure 2'is a transverse section taken on the line of Figure 1.

Figure 3 is a side cleva tion of the cap and combined lamp receptacle and switch member, parts being broken away to disclose the construction more clearly.

Most pocket flashlights are made with a switch positioned on the sides'thereof. The

switch is usually provided with a movable actuating member which protrudes considerably from the sides of the flashlight. Freuently while placing the unlighted flashllght in a persons pocket, or even after the light is placed therein, the actuating member of the switch will he accidentally moved to close the circuit. Thus without-knowledge to the person, the battery will be needlessly run down and the attendant annoyances precipitated, In accordance with myinvention the switch is for the most part arranged on the inner side of the flashlight the lamp is adapted 1921. Serial No. 487,425.

ent type are provided. As a consequence of the foregoing the sides of the device may be thus cleared of all undesirable protuberances.

The flashlight in the form illustrated comprises the usual cylindrical casing 4 preferably formed of insulating material and provided at each end with threaded metallic rings 6 and 7 suitabl fixed to the casing. The lamp 8 of the flas light is supported in the reflector 9 which together with. the lens 12 are held in proper position by the threaded retaining member 13 which engages the ring 6. Arranged within the casing is the battery 14 provided at its opposite ends with terminals 16 and 17 the former of which is adapted to contact with one of the electrodes 18 of the lamp. The other electrode 19 of to be connected to the terminal 17 by means of the grounded. reflector, a conductor 21, switch 22 and preferably spring 23. The conductor 21 comprises a'longitudinal strip fixed to the inner side of the casing and having one end in contact with the reflector and the other end adapted for cooperation with the switch.

Threaded for engagement with the ring 7 is a'cap or closure25 to the inner face of which is secured a cylindrical member 26 preferably in the form of a receptacle. The

receptacle which is preferably formed of an electric conducting material is insulated from the cap, and is arranged to extend in-' wardly within the casing so as to enable it to contact with the conductor. A "portion of the side wall of the receptacle is cut away so that upon the slight rotation of the cap the segmental wall of the receptacle or the cut away portion thereof may be made to alternately engage correspondingly closing or opening the lighting circuit. The spring 23 which forms a part of the circuit is preferably secured to the top of receptacle and is adapted to hold the battery terminal 16 and lamp electrode 18 in proper contact. The spring 23 also functions to hold the threaded portions of the ring? and cap 25 in frictional engagement, thereby preventing any accidental rotation of the cap.

' It will thus-be seen that the flashlight may be lighted or extinguished by merely rotating the cap, and furthermore that the side walls of the casing are enabled to be perfectthe conductor, thereby ly smooth, and that practically all danger of the accidental closing of the switch is eliminated. I

By referring to Figure 3 it will be noted that the receptacle is well adapted for the storage of extra lamps or the like, thus adding greatly to the convenience of the user. The lamps in the storage receptacle are preferably packed in tissue or the like so that they will not rattle or breakby contact with each other. I claim:
