Continuation of application Serial No. 248,303, filedAugust 5, 1918., This application filed. October 2,

' T 0 all whom it may concern.

.Be it known that I, VVILLIAM G. Woon, a

citizen of the United States, residing at adjusted wlth relation to the forks in which they are supported.

One of the objects of the present invention is to provide a simple and substantial mounting for headlights, such as are employed on automobiles and the like, whereby the vertical angular position of the headlights may be adjusted with relation to the forks supporting the same. Another ob ect of the invention is to "provide a mounting of without resorting the character described which may be attached to any standard form of headlight and also a mounting of novel construction which permits a wide range of adjustment to. bending of the forks, and which is provided with means for positiyely locking the headlights when; adjusted. Further objects will hereinaftera'ppear.

Having reference to the accompanying drawings Figure 1 is a plan view of the type of lamp shown in my co-pending application, said view also showing the mounting whereby the vertical angular adjustment of the headlight is obtained.

Fig. 2 is an enlarged detail side elevation of the mounting. Fig. 3 is a vertical cross section on the line 3-3 of Fig. 1. V

Fig. 4 is a plan view of a standard form of headlight employing a parabolic reflector showing the application of the invention.

Referring to the drawings in detail, A indicates the casing of a headlight such as shown in my co-pending application previously referred to and B the casing of a standard form of headlight employing a parabolic reflector. mobile headlights in use today are supported on forks rigidly secured to the main frame of the car or to the forward mud guards. Many prior headlights are pro- Most forms of auto- Serial No. 327,908.

vided with fixed perforated lugs on each 7 side for the reception of the forks and as the lugs and the forks are fixed and nonadjustable, it is obvious that vertical ad ustinent' of the beams projected by the headlights can only be obtained by bending the forks. i

, The purpose of the present invention isto provlde a mounting which permits vertical angular adjustment of the headlights with relation to the forks without resorting to the necessity of bending the forks. This'is accomplished in the following manner: Referring to Figs. 1, 2 and 3, A indicates the casing of a headlight, which is pivotally mounted on a pair of bearing members arranged one on each side thereof. Each 2 bearing member consists of a pair of disks 2 and 3 which extend through the walls of thecasing and about which the casing is other by means of a set-screw 5. The disks 2 and 3 are each provided with an annular shoulder 6 of reduced! diameter, thereby formingan annular channel ,for the-reception of an annular shoulder 7 formed on the casing, said shoulder securing the disks 2 and 3 against lateral movement with relat1on to the casing and simultaneously permlttlng turning movement of the casin with relation to the disks. 6

Formed on each outer disk 3 is a perforated lug ,8, through which the'fork supporting the headlight extends each arm of the fork passing through the perforation or opening indicated at 9, and being secured therein bya set-screw 10. Also formed on .each disk 3 is a radially extending arm 11,

in the outer end of which is formed a seg-' mental slot 12 through which extends a clamp screw 13. This screw is receivedby a threaded opening 14: formed in the wall of the casing and serves the function of securing the casing against turning movement about the disks 2 and 3. V r

A slight modification of the structure shown in Figs. 1, 2 and 3 is resorted to when applying the mounting to a headlight such as shown in Fig. 4:; that is, the disks 2 and 3 are'in this instance turnably mounted in a plate l5 formed integrally with or otherwise secured to the casing B; the clamp screw 16 being also secured by the plate 15, as shown.

In actual operation with the headlights V placed in position on the forks, it is possible to raise or lower the projected beams with relation to the roadway by merely releasing the thumb screws 13. The casings of the headlights are thenturned about the disks 2 and 3 until the angular adjustment desired is obtained. They are then locked by tightening the clamp screws 13.

The turning movement of the casings with relation to the disks 2 and 3 is limited by the length of the segmental slots 12 formed in the radially projecting arms 11. A wide range of movement or adjustment is, however, obtained due to the length of the segmental slots 12 and it is, therefore, unnecessary at anytime to resort to the bending of the forks when adjustment is desired.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. Thecoinbination with the casing of a headlight and a fork bywhich it is supported, of a pivotal mounting on each side of the casing by which the casing is supported and upon which the casingis turnably mounted, a perforated lug on each supporting member for the reception of the fork, a radially extending arm on each member exteriorly of the caslng, a segmental slot formed in the outer end of each arm,

and a clamping screw extending through each segmental slot and carried by the casing. V Y

,2. The combination with a casing of a headlight and-a fork by which it is supported, of an inner and an outer disk member on each side of the casing about which the casing is turnably mounted, means securing said disk members together, a perforated lug formed on each outer disk member for the reception of the fork, a radially extending arm on each outer disk member, a segmental slot formed in the outer end of each arm, and a clamp screw on each side of the casing extending through each segmental slot. 7

3. A headlight comprising a casing, a source of light in said casing, a reflector cooperating with said light adapted to project, the light forwardly through an aperture formed in the casing, a pair of bearing members adapted to support the headlight, said bearing members projecting through the sides of the casing and being turnably mounted therein, a perforated lug on each bearing member for the reception of a fork or other similar support, a slotted projecting lug on each bearing member, and a screw secured in the casing extending through said slot, one for each bearing member, said screws adapted to lock the bearing member's against turning movement with relation to the casing.

4, The combination set forth in claim 3 wherein the bearing members are formed in two parts, each with a flange, and means for clamping the two parts non-rotatably together with the wall of the casing between the flanges thereof.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
