FLASH-LIGHT-BULB SUPPORT.

Application filed August 14, 1922. Serial No. 581,598.

T 0 all whom it may canoe-m:

Be it known that I, EDMUND R. B'AnANY, a citizen of the United States, residingin the borough of Brooklyn, county of Kings, city and State'of New York, have invented certain new and useful Improvements in Flash-Light'Bulb Supports, of which the following is a specification;

This invention relates to :flashlight' bulb supports.

An important object of my invention is to provide a support of the character mentioned, which is so constructed as to relieve the electric bulb from any excessive shock or impact which may be imparted thereto upon an accidental, or otherwise, undue longitudinal displacement of the battery within the flashlight casing. V V A further object of my invention is to provide a support of the character -m'en- 'tioned in the form of a unitary structure, which is inexpensive to manufacture, easily assembled and reliable in use.

Other objectsand certain advantages of the invention will become apparent from the following description when taken in con nection with the accompanying drawings, in which I r Figure 1 is a side elevation of a flashlight, a portion thereof being broken away to illustrate the several elements of the support embodying my invention.

. Figure 2 is a top plan view of the support.

7 the head 8 as a means for supporting an Figure 3 is a bottom plan view of the support shown in Figure 2.

Figure A} is a view in perspective showing the several elements of the support in their order of assembly.

In the drawings, wherein for the 'pur pose of illustration is shown what I at present consider the preferred form of my'invention, the numeral 5 indicates anelongated casing or housing, adapted toreceive the-rein the usual form of battery 6', having a carbon electrode 7. The casing, as shown, is provided with a conventionaliorm of head 8 having screw threaded engagement with .the casing 5 and provided with the conventional type of lens 9 and lens ring 10.

The support embodying my invention is illustrated as a whole by the numeral 11 and is adapted to be suitably retained within with av central opening 20, to receive the central contact 14: adapted to engage a resilient'tong'ue 21', struck up from a metallic conductor plate-22, with which is associated a similar plate 23;, having a resilient tongue 24 struck therefrom, adapted to electrically engage the central contact 7 of the battery.

The plates and 23 are provided at corresponding ends with openings 25 and 26, re-

spectively, to accommodate rivets 27, which 7 are utilized to retain the plates in their respective positions upon the washer 19,-

the rivets being passed through the insulating washer 15, and relatively large openings 28, provided in the plate 18, the openings 28 being somewhat larger than the rivets 27 for the purpose of preventing short circuiting between the battery 6 and bulb 12 as will be readily appreciated.

The circuit through the bulb 12 is adapted to be controlled by the usual form of switch 29, carried by the casing 5 to which is suitably connected a conductor 30 having elec- ,trical engagement with the plate 18 at or relatively near the peripheral edge thereof. In tracing the circuit through the lamp, it will be observed that the current passes from the electrode 7 through the resilient tongue 24, the plates-22 and 23, the resilient tongue '21, into the lamp 12 through the central contact 14, and out of the same by way oi the outer contact 13, from whence it passes pbnductor 30, which is adapted to be electhrough-the sleeve 17, and plate 18, to the trically connected with or disconnected from the usual form of zinc electrode of the battery by means of the circuit controlling switch 29.

, With the device embodying my invention, 1

it .is apparent that when the bulb 12 is run the same is permitted to slightly yield when a further thrust is exerted thereupon, and

that such resiliency as the tongue 21 might sult from undue displacement of the battery 6 within the container 5, since the tongue 24 is adapted to yield to a material degree, due to its inherentresiliency, when a longitudinal thrust is exerted upon the battery in the direction of p the flashlight head.

Having thus described my invention, I claim:

1. In a flashlight having a bulb and a battery, a bulb support disposed intermediate said bulb and batter comprising a plate having a screw threa ed sleeve adapt ed to receive said bulb, a pair of plates having electric connection with each other resilient tongues carried by said plates, one of said, tongues being-adapted to electrical ly engage the central contact. of said bun,
