Application April 3, 1934, Serial No. 718,838

3 Claims.

This invention relates to folding duplex flashlights. a

The invention will be fully and comprehensively understood from a consideration or" the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not afiect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig 1 is a plan view of my improved folding duplex flashlight and shows a pair of flashlights in axial alignment; and

Fig. 2 is a plan View showing the flashlight of Fig. 1 so positioned that the pair of lights are in side by side parallel relation.

Referring to the drawing for a more detailed description thereof, numerals 3 and 4indicate flashlights of the usual construction, the same being pivotally connected by means of a hinge 5 at their proximal ends so that they may be positioned either in axial alignment, as shown in Fig. 1, or in side by side parallel relation, as shown in Fig. 2. The proximal end of one of the flashlights is provided with a catch '7 adapted to be snapped into an aperture 8 in the flashlight 3 so as to hold the two lights in axial alignment when the lights are desired in that position. In order to hold the lights in parallel relation, as

shown in Fig. 2, the light 3 is provided with a catch 9 adapted to be snapped into an aperture 10 formed in the light 4.

The pair of lights are desirably positioned in axial alignment when they are used by a person walking along the road, so that the forward light may be used for guidance and may be seen by the driver of an oncoming automobile, While the rear light may serve as a signal to automobile drivers coming from the rear.

Either one or both of the lenses in the lights may be of red glass or other color.

When the lights are positioned in parallel relation, the device affords more light than would a single light of the power used in one of the lights.

to aligned position.

3. A pair of hand flashlights having tubular casings and lamps at one end of each, said casings being pivotally connected at their proximal ends to allow them to be moved from parallel to aligned position and vice versa, and means for holding them together in either position.
