ZEITZ, OF CLARKSBURG, WEST VIRGINIA i HEADLIGHT Application filed April 30, 1927; Serial No. 187,774.

My invention relates to improvements in headlights and particularly to a. headlight provided with a reflector adapted to be tilted to direct the light beams at different angles and the invention resides particularly in an improved mounting for the re flector.

In a light structure of this character it is desirable that the reflector be so mounted as to be readily tilted to any desired angle and that in addition the construction be such as to minimize the frictional resistance of the moving parts and prevent any rattle or unnecessary noise. My invention comprises a minimum number of parts; the construction is simple and the parts are readily actuated to accomplish the desired tilting of the reflector and the parts are so coupled together that the reflector is readily and easily tilted and there, is no unnecessary noise or rattle caused by travel of the vehicle over the road.

Other objects and advantages, together with important structural features, will iore fully appear from the following description of the illustrative embodiments of my invention herein shown. from the appended elaims and from the accompanying drawintm, wherein:

Fig. 1 is a vertical sectional view through a headlight en'ihodying my invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is sectional. view through a modified form of a mountin Fig. 5 is a cross-sectional view taken on line 55 of Fig. 4-.

Fig. 6 is a fragmentary elevation of a second modified form of mounting, and

Fig. 7 is a cross-sectional view taken on line 7 -7 of Fig. 6.

In the drawings, 10 indicates the headlight casing provided with a retaining ring 12 and lens 14, and an annular member 16' supported within the casing engaging the lens. The casing is provided with pivotally supported guides and there is mounted with in the casing a reflector 18 provided with an encircling band 20, which is supported upon said guides to travel thereover. In Figs; 1 and 2 the guides are shown as comprising guide members 22 provided with rollers 24; and supported for pivotal move ment upon pivots 26. The band 20 is mounted within the guides 22 to travel over the rollers 24 andpreierably carries an inherent tension which causes it to exert a pressure upon such rollers. The band extends about the reflector 18 and is provided with a socket 28 which extends through the reflector and is adapted to receive a light bulb 30.

In order tov prevent bodily displacement of the band as pressure is exerted thereon to tilt it, the band; here shown is provided with a supplemental arcuate portion 32 which travels through a guide 34 carried by the casing. This guide 34 engages both sides of the member 32 and is formed on a radius so that the rolling movement of the band is permitted.

To actuate the band I provide a conncction 36 which is secured thereto in a suit able fashion itor example, as shown in Fig. 1, and which extends through a tubular mounting 38 caried by the casing. Actuation of this connection 36 in the direction of its length will exerta pressure on the band tencing' to, cause the same to roll through the guides and tilt the reflector in a vertical plane; I j

In order to tilt the reflectorin a horizontal plane, I have provided the band 20 with an angular-1y extending portion 21 to which is attached connection 37, which also extends through the tubular guide 38 to a point outside the casing and through the actuation. of which in the direction of its length pressure is exerted upon theband to cause the same to actuate the, guides 22 upon their pivots 26-to swing the reflector laterally. 1 I Q In Figs. 4 and 5 the guides are shown as comprising a portionAO which issecured to the casing and channeled guide portion 42, which is pivotally supported upon the portion 40 by a ball l i, which hall also engages the band here indicated as 46, which band is secured to the reflector as heretofore set forth and the operation of which is as has been heretofore set forth.

In Figs. 6 and 7 I have shown a second modified form of construction wherein the casing is provided with a bearing plate 4C8 which has a spherical face 5O within which is mounted a ball 52, which ball engages the band here indicated as 54 and which band is provided with a longitudinally extending channel 56 seated upon the ball to hold the hand against lateral displacement.

What- I claim is:

1. In a headlight, a casing having opposed pivotally mounted guides, a reflector within the casing provided with an encircling supporting band mounted within said guides to travel therethrough to tilt the rehector, means engaging the band to actuate the same to travel through the guides, said band provided with a laterally extending portion partially encircling the reflector, and means engaging said angularly extending portion of the band to swing the band upon the pivotal supports of the guides to tilt the reflector.

2. In a headlight, a casing provided with pivotally supported roller guides arranged on opposite sides within a determined plane, a reflector provided with an encircling band mounted within said guides to travel over the rollers thereof to tilt the reflector within said plane, said band so mounted within the guides as to swing the guides about their pivotal supports, means engaging the band to actuate the same to travel through the guides over the rollers and means engaging the band to actuate the same to swing with the guides about their pivot.

3. In a headlight, a casing provided with opposed pivotally supported guides, a reflector within the casing provided with an encircling band mounted within said guides to travel therethrough or to swing therewith about the guide pivots, said band tensioned to exert an outward pressure upon said guides.

4. In a headlight, a casing provided with opposed pivotally supported guides, a reflector within the casing provided with an encircling band mounted within said guides to travel therethrough or to swing therewith about the guide pivots, and a lamp socket carried by the band and extending through the reflector and having a lamp bulb mounted therein.

5. In a headlight, a casing provided with opposed pivotally supported guides, a reflector within the casing provided with an encircling band mounted within said guides to travel therethrough or to swing therewith about the guide pivots, and means engaging the band rearwardly of the reflector to hold it against bodily displacement relative the first mentioned guide members while permitting rolling movement of the hand therethrough.

6. In a headlight, a casing provided with opposed pivotally supported guides, a reflector within the casing provided with an encircling band mounted within said guides to travel therethrough or to swing therewith about the guide pivots, said band provided rearwardly of the reflector with a supplemental arcuate longitudinally extending segment secured thereto at its ends and spaced rearwardly thereof, and a perpendicularly arranged reversely curved guide carried by the casing engaging said supplemental portion to prevent bodily displacement of the band while permitting rolling movement thereof.

7. In a headlight, a casing provided with opposed pivotally supported guides, a reflec tor within the casing provided with an encircling band mounted within said guides to travel therethrough or to swing therewith about the guide pivots, said band provided with an arcuate angularly projecting portion partially encircling the reflector, an arcuate supplemental band portion extending longitudinally of the band and secured thereto at the ends of the supplemental band portion and spaced rearwardly of the band, a reversely curved arcuate guide for the supplemental band carried by the casing and disposed perpendicularly with respect to the supplemental band and engaging the same on opposite sides permitting the travel of said band portion through said guide longitudinally or transversely, means engaging the band to actuate the same to travel over the pivotally supported guides to tilt the reflector, and secondary means engaging the angularly projecting portion of the band to actuate the band to swing the guides upon their pivots to tilt the reflector.

In testimony whereof, I, JAME-s A. STREET, sign this specification.

JAMES A. STREET.
