HEADLIGHT. l

Application led February 9,1924. Serial No. 691,623.

To all wko-m z'z may concern:

Be it known that I, OSCAR It. Hoorrs, a citizen of the United States, and resident of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Headlights; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to headlights particularly applicable to motor driven vehicles.

The object of my invention is to provide a simple, effective and economically constructed headlight which will eliminate r' glare or blinding of a driver facing the lights, but which, at the same time, will produce maximum efficiency with reference to the Volume of light.

The specific object of my invention is to provide a horizontally disposed concavo-convex deflector in connection with the light hood, together with other reflector means, for directing the rays of light upwardly against the concavo-convex deflector, whereby said rays will be broken and indirectly exposed. In other words the light bulb will be at all times concealed from vision of a oncoming driver.

Further objects of the invention are to direct the rays upwardly whereby they are deflected downwardly at a predetermined distance from the vehicle so as to obstruct the vision.

Further objects of my invention are to provide means for concealing the light bulb in connection with means for shifting this concealing blind whereby access may be had for removing or renewing the bulb.

lVith the above and other objects in view the invention consists in certain practices of construction and invention of parts as will be hereinafter set forth in reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a sectional elevation of a headlight embodying the features of my invention.

Figure 2 represents a cross section of the same the section being indicated by the line 2*2 of Figure 1.

Referring by characters to the drawing, l represents a standard metallic hood having the usual front glass plate 2. 'Ihe hood at its rear portion, is formed with a lamp socket 2 which extends obliquely with reference to the curved base of the hood so positioned that the lamp 8 when fitted to a rsplcketis approximately centrally disposed.

lar reflector 4 positioned in axial alignment with the socket. The hood l is also provided with a deflector plate 5, the forward portion of which is troughlike in shape. The

ne lampv socket is fitted` with a semi-circurear portion of the deflector plate 5 is curved y downwardly as shown in Figure l and gradually merges into the forward portion thereof. If desired the cylindrical portion of the deflector plate 5 may be tilted forwardly and downwardly a slight extent, for instance the entire headlight may be set so that its axis points slightly downwardly. rThis deflector is held in place by ribs or lugs 6 which project from the juxtaposed wall of the hood whereby said deflector plate can be readily inserted or removed. The deflector plate is held in position longitudinally by abutting engagement with the rear portion of the hood and forwardly by the glass plate 2.

In order to shield the direct rays of light from the vision of a party in front of the same, I provide a blind 7, the base of which is connected by hinge members 8 to the adjacent inner wall of the hood and approximately in parallel relations with the inclination of the bulb and socket 2. It is evident that the blind can be adjusted in or out so as to change its angle from a set position, as shown in the drawings, and this change of angle, when effected, is permanently held by set screws 9 which pass through lugs in the blind and frictionally engage the walls of the hood. The upper edge of the blind engages the lower edge of the deflector plate and it is cut downwardly in semicircular shape to form in conjunction with the defiector plate, a light discharging throat of such area as to meet general requirements. 'Ihe blind, however, will at all times effectually conceal the light bulb whereby only the reflecting rays of said light bulb are visible.

From the foregoing description it will be manifest that, as indicated by dotted lines, the rays of light will strike the concaved defiector plate which is highly surfaced, and the rays thus reflected will be directed thro-ugh the throat in a forwardly direction, such throat being formed by the deflector plate 5 and the juxtaposed edge of the blind or baffle plate 7. Thus a full volume of light will, at all times, be visible to provide safety when driving at night,

A viv/bile,` at the. Sametime, thefdanger of blind-VV ing onooming'vehcles is entirely eliminated.

While I' have shownrand `described a the claim and that, obviously, the vshape or general designy illustrated may be. departed from tothe taste of the manufacturer.

I claim:-

hood, a baffle extending Vupwardly and for-y Y Wardly from the hottoin Vportion of saidhood and ending a spacedy distanceV from the upmerging into a downwardly *Y y v 'Y tially Spherical rear portion. lheadlight comprising ahell shapedy 'per portion ofioaid hoocLa -lamp1seenred Within said hood rearwardly'of said' 'baille plate' and projecting upwardly and for- ,Wai-elly,y and a detleotor'inounted Within Vsaid said cylindrical forward portion gradually curved substan In testimony that I elaiin the foreg ing I have hereunto` set my hand at Janesville, in
