ELECTRIC HEADLIGHT.

Application led July 12, 1924. -SerialNo. 725,568.'

My invention relates to' a headlight including carrier and battery for the same;

arranged in such a manner that it may be conveniently attached to the operators head around automobiles and other machinery,

as it leaves both hands of the operator free Jand directs the light' exactly on the parts to be operated upon. as a miners'lamp.v

In. the accompanying drawings, one embodiment of the invention is illustrated, and

Figure 1 is a front elevation of the device as attached to an o erators head and body;

Fig. 2 is a top p an view of the head set with the lamp; v

Fig. 3 'is a detail section through the ball and socket joint; l Fig. 4 is a section on the line 1 --4Eof Figure 1 showing the battery box;

Fig. 5l is'a fragmentaryend elevation of the box, and

Fig. `6 is a' section on the line 6-6 of Figure 2.

fn the drawings, the reference nummeral 10 represents the head set of the device and 11 the battery box for the velectric lamp. The head set consists ofv a shield12 to which is attached, as by rivets 13, a resilient clip 11 having forwardly directed arms terminating wlth semi-spherical ball sockets 15.

By means of aset screw and wing nut 16,

the arms 14 may be drawn together in order to clam the cups or sockets 15 around a ball 17 whic is rigidly secured tothe lamp car'- rier 18, as best seen in Figure2. Between the cups and the ball are preferably provided packings 29 of some pliable material, such as leather or rubber. The lamp carrier is of any suitable construction provided with lens 19 in front of the electric lamp 20.

The shield 12 which is preferably made It may. also be used the linings 21 and 22. From the top el the shield l2 extends 'rearwardly a top strap 2 6 also stitched to the linings 21 and 22 and provided with a buckle 27 forlengthening or shortening the same. The -rear end of the to strap has a loop 28 which is taken aroun the side strapl 23 inI order to have slidable engagement therewith.

The reference numeral 30 `'represents a double conductor for the lamp 20 which continues from the samein upward direction through an eyelet 31 near the upper end ofthe shleldJ through a second eyelet 32 onl the upper side of top strap 26 andthrough a third eyelet 33 on the side strap 23.v The other end of the double conductor 330 is taken to the battery box 11 and connected with the cells 34 therein. In Figure 4a battery box con aining two cells has been shown but it is evident that any number of cells may be provided according to thestrengthof the lighty in the lamp. The battery box has a hinged lid 35 held down by ia clasp 36` and at one end of the battery box is'furnished' a switch 37 which,l

when swung in one direction, contacts with the terminal 38 and if swungin the opposite dil'ectionwill be locked by a'clamp39 when no current is furnished for the lamp 20.

4A shoulder strap- 40 is secured on the battery box, as best seen in Figure 1, so that the operator may 'conveniently carry the battery. box on one side or on his back; The reference numeral 41 designatesabelt secured to the battery box and adapted to be taken around the operators body to hold the box firmly thereon.

By means of-the ball and socket joints 15 and 17 and the clamping screw v16, it is possible to adjust the position of the lamp in the direction desired so that it may point not only straight ahead of the operator but at any angle upwards, downwards 'or sideways as he may desire.

Having thus described the invention, I claim:

A headlight device comprising an elonof springsteel and curved to the contour' gated plate curved longitudinally to conof the forehead of the operator is rectangu lar-in shape and embedded between the inform to the forehead, a'casing for said plate formed of front and rear strips of Vgreater dimensions than saidV plate and having their edge portions extending from theplate and joined ther, said front. stri being formed with an openinginterme 'ate its' length and width, ahead encircling-strap set @ma .a one end a me and of mdin',

a fastener connected with the other end of said casing and adapted for adjustable engagement with the free end of said strap to vhold the strap tightly about the head, an upper. strap for extendingv over the head having its forward end secure-d to said casing intermediate the ends of the casing and havin its rear end provided with a loop: to slidably receive said head encircling strap, a U-sliaped bearing bracket secured to said plate within the opening-of the front strip and having. its arms projected lforwardly 'from `the plate and casing .and terminating in socket-forming-cups, a lamp including 'a casing and a shank extending rearwardl?I '15 1 f for tight gripping of the ballbetween the 20 cups. e i Y In testimony whereof I affix my signature.
