Application March‘ 26, 1936, Serial No. 70,946 4 Claims. (01. 240—10.6) . This invention relates to a ?ashlight that is especially useful in connection with signaling. bright to re?ect rays of light from the lamp bulb of the ?ashlight against the inside surfaces of By this invention a ?ashlight is made in sucha way that it is readily visible from the sides as well as the lighted end. _ the glass II to light it up. . The usual re?ector l5 for the ?ashlight is located at the upper end of the'flashlight I with 5 In carrying out the invention glass windows,’ the lamp bulb I6 as usual. which may be made of different colors if desired, Instead of having a re?ector l3 to re?ect rays ‘are provided'along the circular periphery of the v of light against the glass ring II, as shown in cap which holds the glass, these windows being in Fig. 2, the glass ring may be made as shown in Fig. 4 with annular dovetail shaped grooves I! 10 10 position so that they are illuminated by rays of light from the regular bulb for the light, so that therein to provide stepped or o?set portions with these windows are conspicuously .visible from the annular sloping re?ecting surface I! and with 1 sides of the ?ashlight. The invention will be understood from the description in connection with the accompanying drawing, in which Fig. 1 is a side view of the ?ashlight in which the invention is included; Fig. 2-is a section along the line 2-2 of Fig. 1; Fig. 3 is a section along the line 3-3 of Fig. 2; and Fig. 4 is a section similar to Fig. 2 showing a modi?cation. In the drawing, reference character I indicates a ?ashlight that may be provided with the usual button switch 2 along one side and screw cap 3 at its lower end for replacing the battery. The upper end of the ?ashlight is screw threaded in circular vertical portions 20, so that the rays of light which strike the surfaces I! are re?ected against the portions 20 and illuminate the same to make the glass ring l'l conspicuously visible. Other means can be used to avoid the likeli hood of the glass ring that closes the windows I0 being invisible or only dimly visible because the rays from the bulb- l6 passing near the inner surface of the ring extend so nearly parallel thereto. For example, the inside surface of the glass ring may be provided with irregularities, such as hills and valleys, beads, bumps, or stria tions, thus interrupting rays of light and making the outside of this glass more readily visible. the usual way as indicated by thereference char‘- a'cter 4. The usual cap of a ?ashlight at the lamp bulb 30 end is replaced, in the present-invention, by the cap 5. - ‘ - » 20 25 This invention may be used very conveniently as an auxiliary marine light, especially when the glass is made up of semi-circular portions that are respectively colored red‘ and green. Signal- 30 ing with this device when carried in the user's This cap 5 is provided with a screw threaded portion 6 by which it is screwed onto the screw thl'eaded end 4 0f the flashlight l. The screw threaded Portion 5 is “in?ected by a plurality of hand is also facilitated, because the light can be ‘seen from the front as well as the sides. There fore it is considerably safer for pedestrians to use on highways and is also well adapted for 35 integral metal strips ‘I to the top portion 8 of the use by traffic omcers at night. cap which may be made octagonal around the upper edge similar‘ to the way caps of this sort are frequently made. The usual glass 9 is carried ‘ 40 at the outer end of the cap 5. Arc-shaped windows It are left between the strips 1 and circular or arc-shaped glass H ?ts inside of the cap 5 against the inner surfaces of the strips 1. 5.5 15 I claim: ' ' ; _ 1. In a ?ashlight having a lamp bulb, a cap at the- lamp end having windows, and a circular strip of colored glass in front of said windows, 40 said glass being provided along its inner surface with an annular rib having an outwardly re?ect ing surface in the path of rays of light from said This glass may be made in the form‘ ‘ lamp bulb.
