A cap-plate [8 which may be formed of the same material as that of the frame comprises a medial semi-cylindrical barrel portion I! and a pair of flanges 20 extending from the sides thereof to cooperate with the flanges I 6 and are perforated correspondingly therewith. One or two screw-bolts 2| extend through said perforations on each side of the frame whereby a lamp-socket attached to the cord 9 may be readily and securely mounted in the frame. With the employment of a relatively wide cap-plate I8 lamps of greater or less candlepower varying in their lengths may be accommodated in the frame and secured with equal facility.

With the frame-member constructed and combined substantially in the manner described, with an electric-light bulb 22 operatively mounted in the terminal socket I therefor, and the socket clamped to the frame with the cord therefrom extending through the channel 3 and connected to a source of electric current, the device is ready for use and mounting upon the users head. This is accomplished by stretching the band-portions I 2 apart and placing over thehead sothat the band lightly and resiliently grip the sides of the head over the ears and across the temples while the lamp and reflector therefor extend frontally above the eyes which are protected from the direct rays from the lamp by the reflector 6. The frame-member carrying the current wires on its upper side does not come in contact with the head of the wearer at any point: the front and rear portions thereof are held away from the head by the elastic band and the channeled portions are arched above and away from the head so that no possibility of current leakage or short circuiting that may reach the body is to be feared, and especially so should the frame be composed of non-conducting material as is contemplated.

The ease and convenience with which the familiar and universally used electric-light cord assembly usually found in every household may be utilized and combined with my improved headfrarne to provide a head-light for facilitating and illuminating the many jobs and chores about a home, together with its simple and economical construction making it available at a relatively low cost are distinctive and essential qualities of the invention.

I have provided a light and serviceable guard for the lamp utilized in my improved head-light, which consists of a continuous wire cage hingedly mounted upon the reflector 6 and together with the reflector fully enclosing the lamp to safeguard it from injury, and providing ready access to the lamp for disassembling or for making replacements.

A substantially tubular hinge-member 23 is formed or secured at the outer extremity and upon the inner side of the reflector 6 and symmetrically with the longitudinal axis thereof. Said hinge-member may be formed by turning inwardly an integral tab 24 of the reflector material and securing the extremity thereof with a rivet 25. A spacing frame is provided consisting of a pair of semi-circular plates 26 and 21 connected together at their extremities 2B and arranged at approximately ninety degrees divergence. A plurality of apertures 29 are formed in said arcuate plates for the insertion of guardwires therethrough, as will be later explained. A convenient and preferred mode of forming said plates and that shown in the drawing is to diecut an annulus from a sheet metal plate together with the apertures 28 and then bend V annulus diametrically at their apices 28 to obtain an integral structure.

A length of wire 30 of relatively ductile 'material, such as aluminum, is formed with rectangular bends 3| at its middle portion and the two ends 32 of even lengths are threaded through the apertures 29 in the arcuate plates 28 21. Said ends are then each given a bend at l and threaded in opposite directions through thl: barrel portion 23 of the hinge-member and an! thence continued at 34 reversely in parallel with the portions 32 through the plates 26 and 21 to their extremities where hooks 35 are formed engageable at each side in notches 36 formed at tion 5 of the frame-member and secured therein by the clamp it so that the forward end of the light terminates approximately midway of the length of the reflector.

Having described my invention, what I claim is:

1. A head-lamp support, comprising a curved frame adapted to arch over the head of the wearer and to'extend a spaced distance forwardly and rearwardly thereof, means to retain an electric extension-cord along said frame in detachable condition, clamping means upon the forward end of said; frame to secure a lamp thereto, and an elastic band secured to the opposite ends of said frame for gripping the sides only of the head of the wearer therebetween, thereby securely supporting the lamp without exerting clamping pressure on the forehead.

. 2. A head-lamp support, comprising a curved frame arranged to arch over the head of the wearer and to extend a. spaced distance forwardly and rearwardly thereof, said frame having a longitudinal channel formed along its upper portion to receive an electric extension-cord in detachable condition, clamping means upon the forward end of said frame to secure a lamp thereto, and an elastic band secured to the opposite ends of said frame to grip the sides only of the head of the wearer therebetween, thereby supporting the lamp without exerting clamping pressure on the forehead.

3. A head-lamp support, comprising a curved frame arranged to arch over the head of the wearer and to extend a spaced distance forwardly and rearwardly thereof, said frame having a longitudinal channel formed along its upper portion to receive an electric extension-cord in detachable condition, the margins of said channel having a plurality of projections extending over said channel in staggered relation, clamping 'means upon the for-ward end of said frame to secure a lamp thereto, laterally directed flanges extending from the rear end of said frame, and an elastic band secured to the forward end of said frame and to said flanges to grip the head of the wearer therebetween, thereby supporting the lamp without exerting clamping pressure on the forehead.

4. A head-lamp support, comprising a curved frame arranged to arch over the head of the same at a plurality of points, thereby supporting the head-lamp in balanced relationship to the head without the exertion of clamping pressure reflector and to said flanges arranged to grip the head of the wearer therebetween, threby supporting the lamp without exerting clamping pressure on the forehead, clamping devices to secure ithe lamp attached to said cord to said frame, and

lamp-guard hingedly mounted on said reflector at one end and detachably connected to the frame at its opposite end. 5. A support for a head-lamp comprising a substantially arcuate elongated member adapted 'to extend longitudinally over the head of the wearer and to carry thereon a lamp and means for lighting the same, the elongated member terminating forwardly of the forehead and out of contact therewith, and head engaging means comprising elastic band means interconnecting the forward and rearward terminal portions of the elongated member and adapted to engage the opposite sides only of the head of the wearer, thereby supporting the head-lamp in a balanced position without the exertion of clamping pressure on either the forehead or the back of the head.

6. A support for a head-lamp comprising an elongated member adapted to extend longitudinally over the head of the wearer and to carry thereon a lamp and means for lighting the same, the elongated member extending forwardly of the forehead and out of contact therewith, and head engaging means comprising an elastic band means attached to the forward terminal portion of the elongated member and to the rearward terminal portion of the elongated member, the rearward terminal portion of the elongated member receiving said elastic band and supporting the on either the front or back portions thereof.

7. In combination with a head-lamp comprising a lamp, means for lighting the lamp, and a reflector; a support comprising an arcuate member adapted to extend longitudinally over the head of the wearer, and to terminate forwardly of the forehead of the wearer and out of contact therewith, the reflector being positioned at the forward terminal portion of the arcuate support in rigid relationship therewith to form a substantially integral extension of said terminal;

means on the arcuate support for mounting thereon the lamp and the lamp lighting means, and elastic band means interconnecting the refiector and the rearward terminal portion of the arcuate support and adapted to engage each side of the head of the wearer and to clasp the same, thereby supporting the head-lamp without the exertion of clamping pressure on the forehead.
