` UNITED STATES PATENT oEEIcE. y

EMIL GRAH,4 OF TOLEDO, OHIO.

FLASH-LIGHT.

Application led October 22, 1914. Serial N o. 867,942.

To all whom t ma'g/ concern.'

' Be it known that I, EMU. GRAU, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented a new and useful Flash-Light, of' which the following is a specification.

rlhis invention relates to electric current `conipletir/ig attaching devices.

rl`his invention has utility when incorporated in connection with a pair of electric current supply terminals, say with a dry celljor battery for forming an illuminating device. p

Referring to the drawings: Figure 1 1s a fragmentary side elevation of a flashlight embodying the invention; Fig. 2 is a plan view of' the device of' Fig. 1, with a portion of the reflector broken away; Fig. 3 is a side elevation of. the attachment; and Figs. 4 and 5 show attachn'ient adaptations to cells.

The dry cell lor battery 1 lnay be provided with a waterproof cap 2ifl desired. The battery has the electric current supply terminals 3, 4. Upon one of these terminals may be threaded the insulator 5, having the flange. G against which may abut the lower coil of the conductor elelnent or wire having the socket coil portion 7. The insulator 5 accordingly has 'centrally thereof the threaded seat for the supply terminal protruding therethrough, while exteriorly it has the threaded seat for holding the coils 7 of the wire conductor. The wire conductor may .thus beconveniently and firmly mounted in position with its flexible integral portion or arm 8 to be bent to touch the other terminal, or swung upward and lapped thereover to hold a circuit'closed, as shown in Fig. 1. For continuous lighting of the lamp 9 having the terminal 10 the arm 8 continuous with the conductor element coil 7 may -be snapped over the terminal 3. The other lamp terminal 11 directly contacts the cell terminal 4 protruding through the insulatorl 5, thereby completing the circuit.v

Mounted upon the attachment to surround the lamp 9 is the reflector 12 through which may extend the end-13 of the conductor wire to assist in interlocking mounting .of the refiector 12, while the tubular eXtension 14 of the reflector 12 may be pressed against the coils 5 of the outside of the socket and strengthen the interlocking mounting of the reflector. In the article of Specification of Letters Patent.

Patented Nov, 30,1915.

manufacture disclosed there is a small Aand effective. flashlight attachment for batteries or dry cells.

The showing of the attachment mounted and operated as in Fig. 2 shows the ready adaptation for intermittent or flashlight use, in that the arm 8 may be easily flexed by one finger to close the. circuit for giving the desired illumination. n

The device is compact, simple and reliable, and involves no intern'iediate joints to cause trouble.

The sleeve portion 14 of' the. reflector 12 may be of such extent as to protect from moisture the lamp terminals notwithstandingv the screwing in of the lamp may tend to open up the socket coils a little. This opening up of the socket coils provides an automatic gripping of the lamp against accidental working loose of the lamp from the socket. i

lnasmuch as the conductor element of the attachn'lent has its arm 8 of material readily configured or bent to various directions, there is convenient adaptation of the flash light for use as a lamp by bending the terminal il to a horizontaly position to permit the cell to rest on its base, and' then the arm S is also bent to move in the desired plane as to terminal 4 (Fig. 4). (ells having a horizontally projecting `terminal (Fig. 5) may have the socket mounted thereon, and the, arm bent to contact the other terminal.

lVhat is claimed and it is desired to secure by Letters Patent is:

1. A flash light comprising the combination with a cell having a pair of' terminals of an insulator mounted upon one terminal, a conductor wire coiled upon said insulator to form a lamp socket and having a fiexible arm movable to engage the other' terminal, a reflector mounted on the socket, and a lamp seated in the socket.

2. In an electric illuminating device, a continuous wire conductor coiled for a portion of its length to form a socket for a lamp, and means comprising insulating material to secure said socket to a terminal, the uneoiled portion of the conductor eX- tending away from said socket and adapted to engage a second terminal.

3. In an electric illuminating device, a wire conductor coiled to form a socket for a lamp, and a reflector interlocked with the conductor coil.

4. A flashlight attachment for mounting in connection with a pair of laterally spaced terminals, comprising an insulator for mounting on one terminal, `a lamp socket mounted on said insulator and having integral therewith an extension for engaging the other terminal directly, a lamp mounty ed in the socket, and a reflector for the lamp mounted by the socket independently of the lamp.

`5. An article of manufacture for mount ing in connection With a pair of terminals comprising an insulator for mountin upon one terminal, and a Wire conductor or engaging the other terminal and extending t0 coil about the insulator and form a lamp socket.

6. A flashlight comprising the combination with a lamp having a pair of terminals, one threaded and the other central thereof and spaced therefrom, a source of current supply having a conductor leading to the central terminal, an insulator about the conductor adjacent thecentral terminal, and a second conductor fromthe source of current supply embodying a Wire coil section about the threaded terminal and insulator to hold the lamp in position as to the conductor through the insulator, said wire having a flexible extension beyondy the coil lamp holding portion movable to bring the conductors and current supply into circuit closing position, there being interengaging means opposing opening ofthe circuit.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
