Application filed August 20; i925, serial 110.5 1.4232.

This invention relates to reflectors, and

more particularly. to that type which are employed as headlights for vehicles, although it may be used with equal facility as a signal device or upon fixed objects.

' There is employed two reflectors which may be simultaneously or selectively illuminated, and which in'either case, will throw a light in such a manner as to cast no glare in theeyes of the ordinary observer.

-Th'ere is embodied a housing in which a conical reflector is eccentrically mounted, and a second reflector of substantially the form'of an-ell1pt1cal cone, arranged at an angle. in' the said housing By this'construction, it. is possible to throw a beam of light directly forward, and at the same time,

desired configuration. The housing-10, as-

usual, is formed of metal, but, of course, other suitable materials can be employed.

Fitted in the housing 10 and brazed there substantially conical shape having the lower portion of its interior'surfaceof non-reflecting material. It is to be observed that the open end of the cone is substantially flush with the front open end of the housing 10, and that the rear wall 12 of the cone is in abutting relation to the rear wall 13 of the housing. Arranged below vthe conical reflector 11 is shown in Figure 1, is substantially elliptical in transverse cross section, and is tapered so that the entire reflector has the form of an elliptical cone. tor 14 is substantially flush with the open end of the housing 10, and with the open end of the conical reflector 11. His to be 7 observed that the two reflectors are mount' ed in tangential relation, and'that' the re:

to,-or otherwise secured,'isa reflector 11 .of v

a second reflector 14. This reflector, as'

The open end of this reflecflector 14 has its top side, which'is in abut ting relation to the reflector 11, arranged parallel thereto, while the lower side of said reflector 14 is extended at a greater angle than said upper side." Thus thereflector 14 is arranged at an angleto the housing for a purpose which will'be presently described.

' The .rear wall 15 of the reflector'14 is arranged to'abut the rear wall 13015 the hous ing .10, as in the case; of the-reflector 11, and

' it is to beobserved that the two reflector a thereby very-compactly and rigidly arranged within the housing.

oI-I 'DUNTERM'AN, or ,7

Formed in the-rear wall 13 of sai'dhous- 7 .ing are openings 16 which register respectively with suitable openings 1? in therear walls of the respective reflectors. These openings are'each adapted to receive a suit ableilanip mountingg as shown,'which may be secured in position either by the usual method, or such mountings may be brazed or clamped, as desired. A It will be seen that the lamp conical reflector extends parallel to the axis oftliecasing, while the lamp 19 of'the coni e calielliptical reflector is arranged at an angle to the'axis of the casing,'so asto be appropriately positioned 'wvithin the angularly disposed reflector 14. 1 I

Referring to Figure l, it will be seen that byreason of the angular position of the re 18 bf the flector -14 and the disposition of its lamp therein, that said lamp is only partially visilamp is substantially concealed, the contour of the reflector permits of the downward vpropagation of a steady and non-glaring beam, as, for example, to illumlnatea roadway. 1

The'said reflectors may have their open ends provided with any suitable lens, al-

though this is not essential, and the openings ble to the ordinary observer, but while this in the housing will obviously be closed to provide a neat structure and prevent the admission of foreign matter. Y

It isto'be understood that the reflectors may be either simultaneously or selectively illuminated. i p

For example, the conical reflector may be found desirable for city use. where the streets are usually lw'ell illuminated, and the roadway smooth, while thejconi'cal elliptical reflector may be "employedupon roads of doubtfulcontour, or "V108 versa.

It is to be observed that the conical-reflector will throw a difiusedlight which will 7 approaching the head lamp.

The device may be used as a signal lantern, and may have suitable colored lens adapted to be illuminated as desired.

An important feature of the invention is the. positioningoi the reflectors within the housing. The conical reflector is brazed at its rear wall to the rear wall of the housing, and this is also true of the conical elliptical reflector. The conical elliptical reflector also engages by reason of its shape,

' the periphery of the open end otthe housing .at two points, and 1S brazed or otherwise secured to the housing at these points. The

conical reflector which is adapted to rest upon the upper side of the conical elliptical reflector in tangential relation thereto, may be brazed o-r soldered to the conical elliptical reflector, and at its point of contact was the open end o'f'the housing it is similarly brazed or soldered to said housing. Byvmak-ing the cones'or reflectors slightly truncated, their rear ends are adapted to fit flush with the rear wall of the housing, so that a rigid construction is provided, while, atthe same time, a simple arrangement may be accomplished by passing the lamp mountings through the registering openings in the rear walls of the respective parts.- Y

each case provision is made for diiiusing the light, while at the same time, the projected light is etficient forall ordinary purposes 7 of a motor vehicle or similar adaptation.

We claim A device of the character described comprising a housing, reflectors disposed in said housing, one of said reflectors having the form of a truncated cone, a second reflector disposed in said housing and having the form of atruncated cone elliptical in cross section, said second mentioned reflector being arranged in abutting tangential relation to said first mentioned reflector and at an angle to the walls of the housing, said reflectors being secured together and secured at their ends to the adjacent walls of the'housing, the end walls of the reflectors being disposed in abutting relation flush with the wall of the housing, registering openings in the end walls of the reflectors andthe housing to receive lamp mountings, and lamps carried by said mountings and disposed in said reflectors whereby a beam of light is projected forwardly of the housing and a second beam of light is projected downwardly thereof.

In testimony whereof we have hereunto set our hands.
