EDMUND R. BARAINY, OF NEW YORK, N. Y., ASSIGNOR T FBiANCO ELECTRIC CORPORATION, A CORPORATION OF NEW YORK.

FLASH LIGHT.

Application filed December 21, 1921. Serial No. 523,842.

To all whom it may concern: 1

Be it known that I, EDMUND R. BARANY, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain mnewfland useful Improvements in Flash Lights, of which the followin is a specification.

y invention relates to flashlights and has for one of its objects the provision of such a device so constructed that the particular form of electric connectors employed therein may be utilized to center and retain the reflector together with its various cooperative elements in proper relative positions with respect to the battery container and reflector head during assembling and thereafter retain the assembled elements correctly positioned. so A further object of the invention is to so construct the various cooperative elements enterin into the combination as to produce a flashlight which is strong, durable, easily assembled, and reliable in operation. at To these and other ends my invention consists in certain improvements and combinations of parts as will be pointed out with greater particularity in the clalms appended to this specification.

In the drawings Figure 1 is a longitudinal section showing my invention embodied in a flashlight.

Figure 2 is a top plan view of the device shown in Figure 1, with the reflector re 5 moved. V

Figure 3 is an enlarged perspective of one of my improved connector members. I

Referring to the drawin wherein my invention is shown embodie in aflashlight.

the numeral 10 indicates a housing or casing preferably constructed from fibrous or other insulating material within which a battery 11 or other source of current is arranged. The casing or container 10 carries at one end thereof a reflector head 12 the outer end of which is screw-threaded to receive a lens ring 13 adapted to retain in position the usual form of lens 14 which is mounted directly upon a reflector 15, the reflector at its outer end being spaced an appreciable distance from the outer end of the reflector head 12 as shown in Figure 1 to prevent short-circuiting as will e readily appreciated. The reflector 15 is of the parabolical type Jcorrectly located, and to prevent any tion thereof with respect to the container 10.

and is provided with angularly disposed extensions or tubular protrusions 16 which are screw-threaded as shown, and are adapted to receive and retain in an angularly disposed relatlon, a plurality of: electric lamps 17 provided with the conventional formof screw threaded outer contacts 18 which are maintained in screw threaded engagement with the screw threaded portions of the protrusions, 16.

One side of the current supply is electrically connected with the reflector 15 by a more or less resilient contact strip 19 wherei as the other side of the current supply is adapted to be connected with the reflector 15 through the outer contacts, 18, the lamp filaments, not shown, and the central contacts 20 of the lamps by means of suitable electrical connectors 21, 22 and 23 which are supported by the casing 10 and through which the current may be controlled byany suitable form of switch not shown.

The connectors 22 and 23 function also as supports for the reflector 15 and are of a peculiar shape as clearly shown in Figure 1 they being so formed as to enable the reflector 15 to be easily inserted or removed from the reflector head 12 as the occasion may require, to insure accuracy in placing the same in position, to positively retain the same rota- The connectors 22 and 23 are bent to acute angles as shown most clearly in Figure 3 and terminate at their outer ends in'con'tact bases 24 provided with upwardly and slightly outwardly projecting side or looking members 25 and 26. These members 26 -are'at their upper ends flared or curved outwardly to a greater extent than are the ends of the side members 25, this being done for the reason that such aconstruction makes possible a more easy removal or insertion of the reflector 15 as will be readily appreciated inasmuch as it becomes necessary to spring the connectors 22 and 23 and particularly the side members 26 thereof outwardly or awa from. each other when the reflector 15 1s either inserted or removed.

To prevent short-circuiting of the current between thereflector 15 and the connectors 22 and 23 when the reflector 15 is positioned as shown in Figure 1, I provide insulating sleeves 27 which are threaded upon' the screw threaded protrusions 16 and are adapted to snugly fit between the side members 25 and 26 of the connectors 22 and 23. From Figure 1 it will be seen that the insulating sleeves 27 rest upon the connectors .22 and 23 in a position approximately or substantially directly over the end of the casing 10,.fso that part of the weight of the lamps and the reflector is carried by the connectorsfat a point where the bending moment is practically zero, by which arrangement any tendency-of the more or less resilient connectors to be" bent out of shape by the weight of the reflector and lamps is practically eliminated. However, a certain amount of thrust is exerted upon the connectors 22 and 23, and also upon the conductor 17 by the lamps 12 inasmuch as the central contacts 20 of thelamps engageand slightly move these members under tension when the reflector 15 is placed in position, the inherent resiliency of these members being taken advantage of to maintain the central contacts 20 of thelampsin intimate f electrical engagement. with the conductor 17 and the connectors 22 and 23.
