Patented Oct. 29, 1940 l UNITED STATES PATENT OFFICE A' 4 Claims.

This invention relates to a lamp, particularly adapted for use in connection with bicycles, and which may be either clamped upon the bicycle, such as the handle bars, or may be held in the o hand while riding.

The purpose of the invention is to provide a simplified flashelight type of lamp which will provide both a headlight beam and a tail light. This is accomplished by suspending the usual l battery in a tubular housing, such as that now commonly employed in flash lights, together with suitable reflectors so arranged that certain of the rays, preferably the direct rays, from the lamp bulb will be reflected rearwardly about the 16 battery contained in the housing to the rear end thereof and there reflected through a red lens to provide a signal, danger or tail light.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims:

Fig. 1 is a central vertical section taken through the lamp with parts thereof broken away. Fig. 2 is a diagrammatical illustration of the reected light rays. Fig. 3 is a section taken on the line 3-3 of Fig. 1. Fig. 4 is a section taken on the line 4-4 of Fig. 1. Fig. 5 is an elevation of the lamp.

In the drawing there is shown a tubular lamp casing ID provided with a clear glass lens II at the forward end thereof and a red or signal lens I2 at the rear thereof. The casing IIl is provided with the usual switch button I3. Mounted within the casing I0 there is a tubular metal lining I4 having inwardly sprung spacing fingers I5. Said lingers I5 support the usual flash light battery I6 in spaced and floating relation with respect to the lining I4 and casing I0.

The front end of the casing is provided with a screw threaded portion upon which a bezel I'I is threaded for securing the lens II in position against a reecting member I8. Between the reiiecting member and the lining I4 there is a supporting disk I9 having a plurality of apertures 20 spaced around the periphery thereof for admission of light rays therethrough. Said disk is clamped and securely held between the abutting edges of the lining I4 and reflector I8, the latter being held in place between said lining and lens II by the bezel I'I.

The center of the disk I9 is turned up and threaded to provide a socket 2| for the reception of a lamp bulb 22, and also secure in position a concavo-convex reflector 23. The flexing of the disk I9 holds the lamp 22 in contact under spring pressure of the contact plate 24 on the bat-r tery I6.

The rear end of the battery has clamped thereto a concave reflecting surface 25 herein illustrated as a mirror, Abut which may be of reflecting 5 metal. For providing an electric contact with the rear end of the battery, there is provided a contact linger 2,6 which extends radially beyond the periphery of the battery in position to be slidably engaged by the Contact spring 2l mounted 10 upon the switch button I3. Thus the spring 21 maybe caused to slide out of engagement with the terminal of the contact finger 26 to break the circuit and be caused to slide into engagement therewith for closing the circuit. The 16 linger 26 with its terminal, as well as the reflector 25, is clamped to the end of the battery I6 by a flanged ring 28 provided with apertures corresponding with apertures 29 of the disk I9. Said ring also functions to anchor the battery to pre- 20 vent longitudinal rearward movement, and to that end it is held between the abutting ends of the reector 3U and lining I4.

The lens I2 is secured in position by a bezel 29 which screws upon the rear end of the casing 25 I0, clamping said lens against a rear reflector 30 which in turn abuts against the rear end of the lining I4, said reiiector 30 having its central portion open to emit the light rays through the lens I2. 30

The lamp may be readily assembled or disassembled for removal or replacement of the battery by unscrewing the bezel at either end and sliding the parts from the casing I0 other than the lining which would remain therein. The 35 reflector 25 may be readily removed from an old battery and clamped to a new one. When assembled and in use, the depression of the switch button I3 will close a circuit through the strip 2'I, lining I4, disk I9 and lamp 22. 40

When the lamp is illuminated, the rays are directed as indicated in the diagram of' Fig. 2l. The headlight rays projected through the lens II comprise both direct rays from the lamp and the reflected rays from the reiiector 23. These are indicated as rays a, a. More laterally directed rays of the lamp are reected by the refleeting ring I8 rearwardly between the battery and casing to the reflecting ring 30, as indi- 50 cated by the rays b, c and the rays b', c. The reflecting ring 30 directs the rays c to the reflector 25, as indicated at d, which again reflects the rays rearwardly as indicated at e through the colored or signal lens I2. Similarly the rays 55 c are reected as the rays d which are again reected as the rays e.

By reason of the reflector 25, any light projected from the rear toward the lamp will pass through the lens I2 and be projected thereon by the reflector 25 so as to illuminate the colored signal lens even though the lamp 22 is not illuminated.

The invention claimed is:

l. A lamp structure comprising a, casing, a light emitting lens mounted at each end thereof, a battery supported within said casing in spaced relation thereto so as to provide a passageway between said battery and casing throughout the length thereof, a lamp bulb mounted within said ,casing adapted to be illuminated by said battery,

and reflecting means mounted Within said casing for simultaneously projecting light rays from said lamp bulb to one of said lenses and through said passageway to the other lens.

2. A lamp structure comprising` a casing, a light emitting lens secured to each end thereof, a battery supported within said casing, a plurality of inwardly extending projections for sup-porting said battery in spaced relation to at least a portion of the inner periphery of said casing, a lamp bulb carried by said casing at one end of said battery adapted to be illuminated thereby, and reflecting means mounted within said casing for simultaneously directing a portion of the light rays from said bulb directly through one of said lenses and a portion thereof between the battery and casing through the other lens.

3. A lamp structure comprising a, casing having a light emitting lens at each end thereof, a battery carried within said casing, means for supporting said battery in spaced relation to at least a portion of said casing, a lamp bulb carried by said casing adjacent one end of said battery and one of said lenses, a concave reflector directly associated with said lamp bulb for projecting rays directly through said adjacent lens, and an oppositely disposed reflector ring carried by said casing forwardly of said bulb beyond the periphery of said reflector to receive rays from said bulb for reflection between the casing and battery to the other end thereof for projection through the other lens.

4. A lamp structure comprising a casing having a light emitting lens at each end thereof, a battery carried within said casing, means for supporting said battery in spaced relation to at least a portion of said casing, a lamp bulb carried by said casing adjacent one end of said battery and one of said lenses, a concave reflector directly associated with said lamp bulb for projecting rays through said adjacent lens, an oppositely disposed reflector ring carried by said casing forwardly of said bulb beyond the periphery of said refiector to receive rays from said bulb for reflection between the casing and battery to the other end thereof, and a reector ring adapted to receive the rays projected beyond said battery for projecting them upon a centrally positioned reflector adapted to reflect the rays through the other lens.
