" i r' LIGHT.

To all whom it concern:

Be it, known that I, EDMUND R. BARANY, a citizenof the United States, residing in the boron h of Brooklyn, county of Kings city and tate of'New York, have invented certain new and useful Improvements in Flash Lights, of which the following is a specification. I I

This invention relates to portable electric lamps of the type generally. referred to as flashlights.

An important object of the invention is to provide in a flashlight an improved means forvmounting a plurality of electric bulbs together with their several associated cooperative elements, and a novel and improved means for controlling the independent circuits leading to said lamps from a suitable source of electric energy.

Other objects and certain advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawings in which;

Figure 1 is a view partly in section and (partly in elevation of a flashlight embo ying my invention.

Figure 2 is a fragmental sectional view 11- lustratin the flashlight as viewed from the right in *igure 1.

Figure 3 is a transverse sectional view taken on line 3-3 of Figure 1.

Figure 4- is a transverse sectional view taken on line 4-4 of Figure 1.

In the drawingswherein is shown what I at present consider the preferred form of my invention, the numeral '5 indicates an elongated casing, within which is arranged the usual form of cell 6, the carbon electrode 7 of which is arranged centrally within the customary zinc container 8 which forms the opposite electrode of the cell. The cell 6 is rovided with a cardboard or other insulating sleeve 9, which, as will be readily understood, serves to insulate the cell from the casing 5. It may be remarked that while I have shown the source of electrical energy as consisting of a single cell, a plurality of cells may be employed and maintained in an end to end relation within the casing 5 in accordance with usual practice. In order to retain the cell 6'or other suitahis source of electrical energy such as a plurality ofcells, properl positioned within the casing-l employ t e usual form of screw threaded cap 10 which is carried at one end of the casing and provided with a thrust spring 11, one end of which engages the. bottom of the zinc electrode 8 The sprin 11 which is arranged to exert a 1011- gitudinal thrust upon the cell 6 tends to maintain the carbon electrode Lthereof in intimate electrical engagement with a U- shaped conductor strip 12, which is carried by an insulating disc 13, and suitably connected thereto by meansof a rivet 14 which also serves to retain a reflector on aging conductor 15 in position upon the o verse side of the disc 13. This insulating disc is readily removable and is arranged u on a seat 13 formed at one end of the casing 5. It will be readily appreciated that by this construction rapid assembly of the device is made possible. The reflector engaging conductor 15 projects an appreciabledistance above the u per face of the disc 13 and at its free en is maintained in engagement with a reflector 16 which is arranged cen-= trally within a reflector head 17, carried by the casing 5. The reflector 16 in this particular ty e of flashlight is insulated from the casing y means of an insulating ring 18, which is adapted to rest upon-a ledge 19, formed in the reflector head relatively near the outer end thereof. Upon the reflector 16 there is arranged the usual'form of lens or closure 20 which is retained in position by means of a lens ring 21 having screw threaded engagement with the reflector head 17 at the outer end thereof.

'The reflector 16 is provided centrally with a screw threaded support 22 adapted to receive the screw threaded outer contact 23 of an electric lamp 2%, the central contact 25 of which projects a slight distance into the reflector head 17 as clearly shown in Figure 1. Adjacent the lamp 2% there is provided a pairof auxiliary amp supports 26 and 27 which project an appreciable distance into the reflector head 17. These supports are screw --threaded at their lower ends as shown at 28 and 29 and are adapted to receive respectively the screw threaded

outer contacts

30 and 31 of

electric lamps

32 and 33. The lower ends of the

supports

26 and 27 are provided with

insulating rings

34 and 35 which are adapted to prevent short circuiting between the

lamps

32 and 33 and

conductors

36 and 37 respectively.

The

conductors

36 and 37 are carried by tially identical, are bent to provide

contact bases

40 and 41 adapted to engage respectively the

central contacts

42 and 43 of the 1 lamps 32 and 33] The

contact bases

40 and 41 are provided with oppositely disposed resilient fingers 44 and intermediate resilient arms 45 which are grouped about the insulating rings 34 and 35when thereflector 16 is placed in position within the reflector head 17. It will be appreciated that by reason of the position of the fingers 44 and the arms 45, the

conductors

36 and 37 may be utilized to a certain extent to insure a correct positioning of the reflector 16 ,when the device is being assembled.v Since the

conductors

36 and 37 are more or less resilient they function also as. a means for efl'ectively retaining the, insulating support 13 properly positioned upon its seat 13' under all conditions when the lens ring 21 is .run down into its proper position as shown in Figures 1 and 2. l

As a means for closing the circuit through the several lamps I rovide a plurality of slides 46, 47 and 48 wiiich are mounted upon the casing 5 in the usual manner and provided respectively with

elongated conductor strips

49, 50 and 51, arranged within the casing 5. These strips are, at their up or ends, bent to provide

feet

52, 53 and 54. 13y moving the intermediate slide 47 the strip 50 is so moved as to bring its foot 53 into contact with a rivet 55, which serves to secure a conductor strip 56 to the disc 13,

which conductor strip is bent into a U-shape at one end and adapted to en age the central contact 25 of the lamp 24. y so actuating the slide 47 current from the cell 6 or other source of electrical supply is permitted to pass through the conductor 12, the reflector engaging conductor 15, the reflector 16, the outer contact 23 of the lamp 24 from whence it travels through the filament thereof to the central contact 25, thence through the conductor 56 to the conductor 50 and back to the zinc container 8 by way of the casing 5 and the spring 11. If the central lamp 24 should burn out the secondary lamp 32 may be readily placed in circuit by so moving the slide 46 as to bring the foot 52 of the conductor 49 into engagement with the rivet 38 in which case the current from the cell 6 or other source of supply is permitted to travel through the conductor 12, the reflector engaging conductor 15, the reflector 16, into the lamp 32 through the outer contact 30, out of the lamp 32 through the central contact 42 to the conductor 36 from whence it travels through the conductor 49 and back to the zinc electrode 8 b way of the casin 5, and the spring 11. hould it be desired to place the lamp 33 in circuit, the slide 48 is so moved as to bring the foot 54 of the conductor 51 into engagement with the rivet 39 thereby permitting the current to'travel through the conductor 12, the reflector engaging conductor 15, the reflector 16, into the lamp 33 through the outer contact .31, out of the lamp 33 through the central contact 43 to the conductor 37, through the conductor 51 back to the zinc electrode 8, by we of the casing 5 and the spring 11.

1 will be noted that the circuit through anyone of the

lamps

24, 32 and 33 may be closed independently of each other in the event thatit is desired to place only one lamp in circuit with a source of electrical supply. If, on the other hand it is desired to place two or more of the lamps in circuit this may be accomplished by so moving the lected to function collectively as a source of illumination. I
