' Application filed July 16, 1926. Serial No. 12 2,936.
D To the attainment of the al.)ove, thc improvement resides in the construct ion, com
bination and operative associal ion of parts, a satisfactory embodiment of which is ex.- emplified by the accompanying drawings.
In the drawings: Figure 1 is a front elevation of the improvement.
Fi-gure 2is a side elevation tlIGIGOf-Wltli parts 1 in section.
In the showing of the drawings my -im-' provement is employed in connection with the ordinary. type of electric flash lights. Thus the'improvement embodies a. hollow handle portion 1 which, ordinarily serves 5 as a pocket for a storage battery. In this instance, of'cour'se, the battery is not employed. There. is screwed'on one end of the body 1' a semi-spherical head 2, and
" in this head there is a parabolic reflector 3. Between the head and body 3 there is a bulb 4. In .this instance 'thebulb is frosted or coated with' a radium'paste or similar luminous substance. The 'head 3 has screwed thereon the usual cap that se- 5 cures the lens 5 thereto. The'inner face of the lens 5, from ajpoint adjacent the cencular coatin luminous su stance, indicated by the 'nu-f meral 6. It is to be noted that the Inner 40 ter and theperiphery thereof, has a cirof radium paste or similar edge of the luminous surface 6 is ar ranged centrally with respect to the coated bulb 4. The radium. pasteor similarlun'iinous substance will castslightrays of light against the reflector 3, the substance 6 hav-v ing a similar effect, and these reflected rays will be directed through the central portion 7 of the lens 5. The result is that I haveproduced a simple lighting'element which can be observed for a considerable distance therefrom'in darkness or,at night a 1 time, and the rays of light reflected from my improvementare at least equal to those reflected from that classfof small lamps known "as glow lights]? I @Having described the invention, .1 claim:-- t I A device for the purpose set forth, comprising, a body having a reflectoron the outer; end thereof, a globular member een-" trally seated in the reflector and treated with a luminous substance, a lens on the I outer face of the reflector and said lens having its inner face provided with a clr- .cular strip of luminous substance and the 5 center of the lens which is not treated with globular body.
In testimony whereof I aflix my signature.
said substance being'disposed opposite the ,f I
