ELECTRIC FLASH-LAMP.

I Application filed October 16, 1915.

To all whom it may concern:

Be it known that I, CHARLES A. BENNETT a citizen of the United States, residing at Galt, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Electric Flash- Lamps, of which the following is a specification.

The invention relates to lamps, and more particularly to the class of electric flash lamps,

The primary object of the invention is the provision of a lamp of this character, wherein the lamp head is fastened directly to the binding post of-a battery, thereby obviating the necessity of inclosing the latter within a casing, the lamp head being of novel construction, for the convenient fastening of the saine on the battery, and also for mounting of the electric bulb therein.

Another object of the invention is the provision of a lamp of this character, wherein the circuit between the bulb and battery is closed in a novel manner, the head of the lamp being designed to connect to any ordinary dry cell battery. I

A further object of the invention is the provision of a lamp'of this character, which is extremely simple in construction, reliable and efficient in its operation, neat and attractive in appearance, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the features of construction, combination of elements and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the accompanying drawing: Figure 1,

is a side elevation of a dry cell battery, showing the electric lamp constructed in accordance with the invention applied. Fig. 2, is an enlarged vertical longitudinal sectional View through the lamp.

Similar reference characters indicate cor responding parts throughout the several views in the drawing.

Referring to the drawing in detail, the letter A, designates generally a dry cell battery, of any ordinary well known construction, B, the exteriorly threaded central binding post, and C, the binding nut thereon.

The lamp comprises a base 5, preferably made from porcelain, although it may be Specification of Letters Patent.

Patented July 4, 1916. Serial No. 56,213.

- from for the insertion of the post B, in the openings, and thereafter the placed upon the post for the fastening the base upon the top of the battery A, and also the securing of the reflector in the seat in said base. An insulating washer is interposed between the reflector and nut,.the washer being mounted upon the post B, While secured'to the reflector body 7, concentrically of the post B, is a-resilient socket said nut C, is

ofv

member 10, in which is detachably engaged the electric light bulb 11, the to being closed in a manner scribed.

Formed at the periphery of the base is a swell or boss 12, having a groove or channel 13, therein, while within the latter andfixed circuit therepresently deto the reflector body 7, is a resilient contact arm 14, the same being normally out of engagement with the zinc wall of the battery,

but is adapted to be pressed against the said wall for closing the circuit between the battery and the bulb for the flashing of the latter. The arm 14, is formed with a push button 15, so that the same can be manipulated by hand with one of the fingers thereof.

From the foregoing it is thought that the 5 construction and manner of use of the lamp will be clearly understood and therefore a more extended explanation has been omitted.

What is claimed is 1. The combination with a dry cell battery, of a lamp comprising a base of non con ducting material having an opening for receiving the center binding post of the battery, a. reflector body, a nut on the post for fastening the base and reflector body on the battery, 2. socket member carried by the reflectorbody for receiving an electric bulb for its engagement with the binding post, and means on the reflector for engagement with the body of the battery to close the circuit to the bulb.

2. The combination with a dry cell, of a lamp including a body of insulation adapted to substantially cover the terminal end of the cell and provided With an opening through which the center terminal of the cell projects, a metal reflector carried by the body, a spring clip carried by the reflector and normally out of contact with the casing of the cell, a lamp socket having a central connection insulated from the reflector and connected to the terminal of the cell, the shell of the socket being electrically connect- -10 ed to the reflector, and a lamp bulb mounted in the socket, whereby the engagement of the spring clip with the casing of the cell, closes the circuit with the cell and bulb.

In testimony whereof I aflix my signature. 15
