Application filed September 30, 1916. Serial No. 123,044.

To allwhom it may concern: I Be it known that I, GEORGE A. LEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain useful Improvements in Fuses, of which the following is a specification, reference being bad therein to the accompanying drawing.

The invention relates to a fuse, and more particularly to the class of electric flash light uses.

The primary object of the invention is the provision of a fuse of this character wherein the base of the fuse has fastened thereon an electric current conductor which supplies heat to an inflammable substance for the ignition thereof so that when the fuse is placed within a flash light pan the same will serve to ignite the flash powder when a circuit is closed to the conductor, thereby enabling the instantaneous lighting of the powder with the use of minimum current and the breaking of the circuit quicker to give the battery or batteries longer life.

Another object of the invention is the provision of a fuse of this character wherein the construction thereof is novel in form so that the same can be readily placed in position in an igniting system or outfit so that on the charging of the fuse with an electric current the same will light the flash powder contained within a flash light pan, the fuse being of a construction to insure the instantaneous lighting of the flash powder.

A further object of the invention is the provision of a fuse of this character wherein the construction thereof affords an instantaneous lighter or igniter for the ignition of flash powder for use in photography.

A still further object of the invention is the provision of a fuse of this character which is extremely simple in construction, thoroughly reliable and efficient in its purpose and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction herein after described, and the scope of the application of which will be indicated in the appended claim.

In the accompanying drawings:

Figure 1 is a top plan view of a fuse constructed in accordance with the invention;

Fig. 2 is a bottom plan view thereof; V -Fig..3 is a vertical sectional view through the fuse;

Fig.4 is an elevation of a flash light pan partly in section, showing the fuse in position therein, and by diagrammatic illustra tion an electric circuit.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawing in detail, the fuse comprises a base piece 5 preferably made from paste-board having the required rigidity, although the same may be made from any other suitable material which will serve as an insulation slab or section and constitute the base for the fuse. F astened in the base 5 are spaced parallel wire staples 6 which have their end portions passed entirely through the base and bent, as at 7, against the face adjacent thereto, and these staples secure in place upon the opposite face of the base 5 the thin or hair-like wire 8 which forms an electric conductor and igniter for a purpose presently described.

Supported upon the base 5 and the wire 8 is an inflammable composition forming a match-like head 9 which, when exploded, will act upon flash light powder for instantaneously firing the same, the fuse being used in a flash light outfit in a manner hereinafter fully described.

In Fig. 4 there is shown a flash light pan 10 which has arranged on its bottom resilient members 11 which serve as holders and contacts for the fuse, the members 11 being provided with binding posts 12 to which are connected the wires 13 of an electric circuit which is opened and closed through the medium of any suitable switch. The members 11 engage the ends 7 of the staples 6 carried by the base 5 when the same is inserted in place upon the holder so that the inflammable head 9 will be exposed through the opening 13 in the bottom of the pan 10, and upon the closing of the electric circuit the current willflow through the wires 13, members 11, staples 6 and wire 8 which, when heated by the electric current, will ignite the inflammable head 9 for exploding the flash light powder contained within the pan 10 for the flashing of light therefrom to be used in photography for the usual purpose.

The construction of the fuse permits the use of less current and causes the igniting instantaneously of the head 9 when the circuit is closed "for the lighting or ignition of the flash powderi From the foregoing description, taken in connection With the accompanying drawing, the construction and manner of use of the hereln described fuse Will be readily apparent and, thereforee more extended-ex phi-nation has been omitted.

Having thus described my invention, I claim:

A fuse of the character described including a relatively thin flat base of non-conducting material, a, wire, disposed across one face of the base, an infiemmable'hea'd carried by the Wire, fasteners formed of conducting material iengageziblethrough the base for clampingthe respective ends of the Wire to the bitse and thus being electrically connected to the Wire, andthe portions of the fasteners on the opposite face of the base {forming 2 GEORGE A; LEY;
