This invention relates to? improvements in fiaslilights 1 V v '"Theprimary ohject'of'this invention' is" the provision of an improved flashlight by means tor which' withia single battery or -seteof batiteries-different, coloretlsi'gna]smaybe simullltaneously flashed froin -opposite ends of-an elongated flashlight casing by the action of a singleswitch. l

'iL' further object of this invention ;-is' t'lie provision or an improved *fi-ashlig'ht, L of the conventional shapg' except that at opposite ends there -are positioned signal lamps, one

' :end having therein ajclearlens and: tlie other 5' {having {a red-"lens, with bulbs?adjacent there- "to e connected in series andope'rated simultaneously by means of a single switch: *{Other"objects andgadvantages of this .in- -venti0n will b e appar'ent during the course of S0 the{following detaileddescription.

'-I'n' the drawings-wherein for the purpose of illustration is shown only a preferred embodiment of the invention, j

Figure 1 is a side elevation of the improved flashlight.

Figure 2 is a longitudinal sectional View taken through the improved flashlight.

1 Figure ,3 is a diagrammatic representation of the circuit of the improved flashlight.

, In the drawings, wherein similar reference characters designate corresponding parts throughout the several views, the letter A may generally designate the improved flashlightpwhich may consists of a casing B adapted to receive a set of batteries C therein,

which are adapted to -operate bulbs D and E placed in opposite ends of the casing and mounted on reflectors F and G respectively, which are held in position by lens supporting closures H and K respectively.

Thecasing B is of conventional formation, preferably being formed of conducting material, although it may beformed of insulation material and suitable conducting strips placed therealong to carryout the object of this invention. It is of elongated cylindrical formation," providing a compartment 10 therein open at both ends of the casing, and

ada ted to receive a plurality of conventional iez's.

The bulb D is screwthreaded into the socket so that the filament lies within the reflector F, and the central terminal oft-hefilament on the socket engages the terminal 46 of the adj acent batterycell 11. The closure H is provided with a screw threaded body 50, adapted to externally screw thread on the threaded end 16 of the casing B, and it is provided with suitable flange means 51 for detachably' supporting a clear lens52. It is apparent that the bulb D is grounded on the socket 40 and the disc 42, but not on the reflector F or the casing B, the same being insulated therefrom by the bushingtl.

A switch housing is secured as at 61 over an opening 62 in the casing B; the compartment in said housing 60 facing the compartment in the housing B and therein'being provided with :a bracket 63 which supports a contact strip .65. The contact strip 65 is covered withinsulation 67 at the bracket 63 'and therealong, except at the opposite ends;

without departing from the spirit of the in vention or thescope of the claim.

I claim:

i In a flashlightthe combination of a flashlight casing of conductive material and of cylindrical elongated formation of a diameter that Will enable a person to place the same bodilyin his or her hand and carry it in the palm between the ends of the casing, a dry cell battery arrangement in the casing having directly opposed positive and negative terminals facing the ends of said casing, an electric bulb in one end of the casing having a terminal thereof in directfengagementwith the adjacent terminal of the-battery and the other terminal of said bulb being insulated from said casing, switch means for operativelyflgrounding the said last mentioned terminal of the said bulb direct upon theconductor casing, a lens on theflashlight casing for said bulb, a second bulb, means supporting the second bulb in the casing at the opposite end from the first mentionedbulbin .di rect contact with the terminal of the battery adjacent said end of the casing, the second mentioned bulb having its other terminal grounded directly on the flashlight casing at all times, and a lenseover the end of the casing for thesecond bulb, of a contrasting color with respect to the lens first mentioned.

ed, I preferably: being; red "and clear respec- From the foregoing description of this in- 5 vention it is'apparent' that a novel type'of flashlight has been provided, which will'find its use by pedestrians walking'upon highways where there are little, if any, illumina- 7 tion; In fact, it has been'recomm'ended and proposed by legislatures that. pedestrians walking in darkness on highways, "where 'there is no illumination, be required to carry some light'by means of whichvehicular driversmaydistinguish such pedestrians. With only to throw the switch 72 to close the circuit andcarrying the flashlight conveniently in hishandi there will:be thrown forwardly i a clear light to illumina te the path ahead-of
