'PATENT oFFics. 1



Application led June 29, 1920, Seriall No. 392,708. Renewed January 10, 1925.

To all whom it may concern -Be it known that I, linie J. -Vooiiiii:iis, a citizen of 'the United States, residing at New York, in the county ol New York and 5 State of New York, have invented certain,

new4 and usefulo Improvements in Flash Lights, of which the following is a speci.

iication. l

This invention relates to flashlights and more particularly-to an ,attachment for a pocket flashlight whereby one or more spare miniature incandescent lamps for the flashany. of the essential parts ot' such standard l flashlights and without materially increasing the size or length of the casing thereof. i

In the illustrated embodiment, the objects and desirable results are obtained by providing a compartment at the rear end of the well known type of flashlight, which coimpartment is formed by an extension applied to the end of the 'casing and serves as a receptacle for one or more spare lamps for the flashlight. o

The above and other objects and the novel features of the invention will be' apparent from the following description taken in conv i nection with theaccompanying drawing, in which Fig. 1 is a View, partly in side elevation and partly in section, showing a flashlight .45 carrying a lamp holder' attachment embodying the present invention, and Figs 2 and 3 are, respectively, side and Vplan views lof the mounting means for supportingthe lamp or lamps 1n the shell of the lamp holder attachment.

Referrin to the drawing, F designates the'tubularfiber or metal casing of a well known-"type oflashlightwhch at-its forward end Vis provided with the usual means for carrying a miniature incandescent lamp, retlector, lens and removable screw cap.

lhe rear end or the casing F is open and Aadapted to .permit the removal and i'cplacey nient of a battery l); which furnishes the current for lighting the lamp at the iront end of the casing. The open end of the casing F is normally closed in the usual manner by means of a! cap C which isidetachably connected to the casing l" in any suitable manner, and' -desirably by a threaded 'portion -15 on the cap C that intertits with a corresponding threaded portion 16 on the exterior of and adjacent the open end of the casing F, such threaded portion lbeing either formed inthe wall of the casing or by means of' a threaded fel-rule secured to the casing.

The battery B is yieldingly held in'A place by suitable meansk such .as a spiral spring S lwhich at one end bears against the rear end ofthe battery and at its other'end has a coil that is adapted to fit in a groove 17 1n the cap C, such cap when attached to the' casing pressing the inner end of the spring against the battery B. The spring holds the battery in operative position iii the casing and is a conductive portion of a lighting circuit including the battery. rap C has a knurled portion.v 18 whereby it may be gripped to readily attach or detach 1 The foregoing features arewell known elements of the usual pocket flashlight and require no additional explanation.

In accordance with the objects and principles of the present invention, I provide an attachment for the above described type lblt' flashlight which may be readily applied i thereto without altering any of the elements -of the flashlight now on the market `and without materially or objectionably increasing `the s ize or length' of such flashlight. These objects are most readiliyl1 obtained jby providing a compartment at t le rear eri/d of the flashlight casing which serves as a receptacle for one or more extra lamps. In the present advantageous arrangement .these desirable results are most readily obtained by providing a lamp holder attachment or carriei-` that is adapted to be 'inserted between the rear end ofthe flashlight casing and the cap thereof and detachably connected to lboth rthe flashlight casing and the cap. Such extension of the flashlight casing is obtained by means of the tubular member or shell T which is made of metal or other suitable material and is provided adjacent its opposite ends with means whereby it may be- `thread 20 adjacent Vone end of the shell T adapted to lit the thread 16 on 'the casing and a threaded-portion 21 adjacent the other opposed ben end of the shell T, to which the threaded portionl 15 of the cap C mayl be detachably connected. A knurled bead 2 2 is provided intermediate the ends of the shell T to facilitate the connection and disconnection of `the shell T to the casing and cap.

The shell T constitutes the receptacle for carrying the spare lamps and may be provided with suitable means therein for supporting such lamps so that they will not be readily damaged by jars or otherwise. The simple arrangement herein illustrated comprises amounting plate or diaphragm P of thin sheet brass or other suitable material, and of substantially the same dialneter'as theinterior of the shell T. The marginal edge portion of the mounting plate P fits into the interior groove 23 formed. by the bead 22 and against the shoulder 24 thereat and may be held against such-shoulder by the end coil of the spring S which is also fitted in the groove 23, and when the attachment is in place on the casingF, the cornpression of s ald spring serves yto securely old the Aplate P and the battery B in position. A

plate P for removably holding one or more eXtra lamps, and vas herein shown, such means comprises- U-shape lspring clips having their bases 25 secured to the `outer face of the mounting, plate by suitable means, such as rivets or'eyelts 26. The upstan'ding spaced spri-n4 lingers 27 are provided with gs or A depressions 28 :adapting themr to yieldingly grip the base 29 of a miniature incandescentl'amp L and-securelyv hold the same. Thespring i'gers 27 of each clip are arranged to receive the bases of the lamps, which may be readilyinserted and removed therefrom at will. The spring clips extend into the spare .part or lamp receptacle or compartment A formed between the top of the cap C and the plate orwall -P and may be arranged in, any suitable manner Yupon the outer'face of the plate P., but in order to economize space and only slightly increase the length of the ordinary flashlight casing, such clips are arranged so vthat they support the lamps or bulbs 4inposition With their axes parallel to the plane of the plate P. Furthermore, it Willbe noted that.y the buitablev means maybe provided on the .carried by said member.

clips Vare arranged vso that the'bulbs supported thereby are in such position that the bulb and base o f one lamp are respectively opposite 'the base and bulb of the other lamp,

. thereby holding the bulbs at a-distance from the Wall of the. shell T and preventing breakage of the bulbs.

The application ofthe attachment to an ordinary flashlight will be readily understood from the drawing and the foregoing descri tion.

plate carrying lamps is in position in thev shell T and it is desired to apply the attach-` ment to an ordinary liashlight, it is merely,

necessary-to detach the usual cap at the rear end of the ashlight, remove the usual spiral spring therein and insert the end' of the coil Assuming that a mounting of such'spring in the groove-23 of the at-tach- -the'compartment A it fis, of course, merely necessary to detach the-cap C, and. inl order to removeor replacea battery it is merely necessary to detach the shell T, the cap and shell being removable as a unit.' l

While 'I have shown land described the invention in detail, it will be Vunderstood that the principlesof the invention may be.

applied in other Ways and that various changes maybe made in the structure herein disclosed without departing from the spirit of the invention'or sacrificing any ofv the-advantages thereof.
