HEADLIGHT.

V Applicatlonflled April 23, 1928. v Serial Ito. 684,601.

Be it known that I, Moses J. DAVIS, a citizen of the Unlted States, residing at Pueblo,

in the county of Pueblo and State of Colo-- rado,'have invented a new and useful Headlight, of which the following is a specificar tlon.

This invention relates to headlights of that type used for example on locomotives.

One of the objects of the invention. isto provide means whereby, through the actuation of a switch, the lamp can be caused to throw either a white light or a colored light.

Another object is to provide a headlight utilizing lamps of the colors to be projected,

said lamps being stationary in the housing and so located that neither of them will interfere with the proper projection of light rays from. the other.

A still further object is to provide improved means for mounting the lamps adjustably whereby they can be positioned ac- 33 Figure 2.

curately with reference to the reflector in the lamp housing.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combination of parts which" will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit of the invention as claimed. In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a side elevation of the headlight.

Figure '2 is a front elevation thereof.

Figure 3 IS an enlarged section on-line Figure 4 is a rear elevation of the lamp support and reflector removed from the housing.

Figure 5 isa diagram of wiring that may be used with the lamps.

Referring to the figures by characters of reference 1 designates a lamp housing provided with the usual lens 2 at the front thereof and a door 3 serves dicated at 4, is formed with a transverse 3. 4 The side walls of this channel are under- 7 I to close one side of the housing. The base of the housing, in-

7 formed along opposite sides of a slide 8 insertable into the channel 5 through the side f the housing. Secured on the slide 8 are standards 9 soldered or otherwise attached to the rear portion of arefiector 10. p

The front portion of the reflector has an ear 11 extending tached to the slide 8.

10 is a pedestal 12 having a tubularbody portio 13 in which is slidably mounted a rotata 1e stem 14. This stem projects downwardlv from an angular-sleeve 15 inwhich downwardly therefrom at-. v

i Secured on the slide 8 back of the reflector is slidably mounted a supporting bar 16. 5 A set screw 17 serves to hold stem 14: against f movement in the body 13 and another set screw 18 is used for holding the bar 16 against movement within the sleeve 15.

An opening 19 is provided in the rear end or apex portion of the reflector 10 and bar 16 extends throughthis opening. An incandescent lamp 20 is carried by the front end portion of bar 16 and is adapted to throw a white light. Another incandescent lamp 21 is carried by bar 16 directly back of lamp 20 and is designed to throw a red light. Both lamps are electrically connected to a switch 2 that can be located in the cab of the l0C( .otive or at any other convenient place. The lamps can be disposed in any suitable circuit such as shown for example in Figure 5.

It is to be understood that the bar 16 die be adjusted vertically and angularly relative to the reflector by loosening the set screw 17 and sliding and'rotating By loosening setscrew 18 bar 16 can be adjusted longitudinally. Thus the lamps 20 and 21. can be properly positioned relative to the reflector.

By moving the switch 22 to one position be placed in circuit and the I the lamp 20 will rays therefrom will be properly reflected by stem 14.

the reflector 10. As the lamp 21 is lpcatedf between lamp 20 and the opening 19 1t will lamp21 will be placed in cirm the red their proper projection will not he iutvrfered with.

By proi 'iding t. headlight such' as de scribed the usual White light projected therefrom can be quickly changed to a red light in the event 01" an emergency or Whenever it is desired to display a danger signal.

While this invention is: designed especially for use on locomotives it 1s to he understood that it can be employed efficiently on boats or wherever :1 head-light 13 used. 7 hat is ('lflllllOd is:

Ina headlight, the combination with a housing and a relieetor therein hav ng an OPG IIi DQLlH the apex ortion thereof, ofav pedestal mounted in jtie housing and back of i he n icetor, a stein rotatably and slidably mountwi iii the pedestal, means for holding Witnesses dir ally through the opening in the reflector,

and into position in front of the reflecting surface, front and rear lamps mounted en the ear and movable therewith into position in front of the opening in the reflector, and

means for closing a, circuit to either lump.

In testimony that I claim the foregoing as my own, I have hereto affixed by signature in the presence of two WiiLEiBSSGS.

' MOSES J. DAVIS.
