OF SAN' FRANCISCO, CALIFORNIA AUTOIEOBILE HEADLIGHT VApplication iled January 23, 1929. Serial No. 334,425.

rIhis invention relates to an automobile* headlight and more particularly to an automobile headlight having an adjustable relector.

" The principal object of this invention is closed in two preferred embodiments, but

it is to be understood that the invention is not conned to these forms because it may be embodied in other forms. It is also to be understood that in and by the claims ol- F lowing the description the invention is desired to be covered in whatsoever form it may be embodied.

Fig. 1 is a vertical sectional view of the headlight.

Fig. 2 is a front elevation of the same.

Fig. 3 is a detail view of the headlight showing one of the slides which carries the reflector.

Fig. l is a side elevation of the modified form of the auxiliary headlight.

Fig. 5 is a vertical sectional view of the headlight shown in Fig. 4c.

Fig. 6 is a back view of the reflector showing the means for connecting it to the slide and operating mechanism, and

Fig. 7 is a pla-n view of the clamp used for securing the lamp on the lling neck of a radiator.

The socket 3 is fixed to the conventional standard 1 which supports the yoke 2. The cylindrical drum portion l of the headlight has the conical back end 3 and is provided with a conventional glass pane l', which is retained in position by means of the flanged ring 5.

llithinthe cylinder 4: are two fixed slides 6 and 7 which carry the reflector 8. The rel-lector is of the concave 'spheroidal type, with a suitable metal backing 9,Y which has extensions 10 and 11 to operate in the slides 6 and 7. The metal backing 9 is connected to a yoke 12,`which is threaded on a rod 13, which is held in a iiXed lateral position by the bushing 14 at the back of the casing 3 The rod 13 is flexibly connected to the rod 16 by means of the universal'joint 15. The rod 16 extends through the dash and is bent to form the crank 17. Turning the crank 17 Vrotates the threaded rod 13 and thereby slides the reflector 8.

The bracket 13 is pivotally mounted behind the light socket 19 with the electric light globe .2O therein. A rubber pad 21 is placed on the back of the socket 19 and contacts and plane 4 to hold the bracketwlS in position and to prevent its rattling.

The insulated wires 22 and 23` extend through an insulated bushing 211 and are connected to the socket 19 in the conventional manner. rlhese wires 22 and 23 carry current from the automobile battery to the light globe 20 when the controlling switch is closed. Y

The focus of the light rays may be varied as may be required by adjusting the position of the reflector 8 with respect to the light bulb 20. fWhen properly adjusted the headlight projects a strong light without the usual attendant glare.

lWhen the pan 4 is removed the bracket 18 may be swung outwardly on its pivot to facilitate the replacement ofthe light'globe 20.

pane 1'l and carries the electric 1n the form of the invention shown in end of the arm 35.

Vthe headlight is curved and is rigid The bolt 34 holds the clamps rigid with the radiator neck.

The yoke 36 depends from the arm 35 and is pivoted thereto by means ot the bolt 33. This bolt may be loosened to permit angular adjustment ot the yoke. The washer holds the yoke in a ixed positon when the nut 40 is tightened. rlhe drum 37 is pivoted to the yoke 36 and is capable ot rotary movement at the will of the driver by means presently described.

The headlight comprises the cylindrical drum 37, having the angular flange 4l containing the glass pane 42. The back 43 of with the cylindrical drum 37.

lVithin `theV drum 37 are two channels 44-45 which` guide the ends of the arms 46-47, which extend from a central member 48. Also projecting from the member 43 are four angularly disposed arms 4.9-50-51 and 52 bent over the edges of the concave spherodial reflector 53.

The member 48 is connectedY to an arm 53 by the bolt 34. This arm extends to the top of the drum 37 and is provided with the hub 57 which engages the threaded rod 56, which is enclosed by the housing 58. The rod 56 isflexibly rconnected to the rod 62 by means ot' two universal joints 59-60, which are 'joined by the rod 61. The rod 62 is' supported by the bearing 64 which extends through the dashboard 66. The under side of the bearing is notched and enga'ges'the plate 65 which is fixed to the dashboard 66.

Longitudinal movement of the rod 62 tilts the headlight on its horizontal axis to raise or lower the beam of light. The notches in the bearing 64 serve as stops to hold the headlight in an adjusted position.

The end of the rod 62 is bent to form a crank 63. Rotation of this crank turns the rod 56 which slides the reflector, thereby adjusting the Jfocus ot the headlight. rlhe light globe 67 is carried in the socket 68 on the pivoted bracket 69, which is similar to that described in connection with the pre- Jerred embodiment ot the invention. rlhe rubber pad 70 bears against the pane 42 to prevent rattling of the bracket.

The wires tor the illumination ot the lamp are shown at 71, 72 and extend through the back of the lamp and are protected by the dielectric bushing 73. Y

Having thus described my invention, what l desire to secure by Letters Patent ot the United States is as follows, but modifications may be made in carrying out the invention as shown in the drawings, and in the above particularly described orm thereof, within the purview of the annexed claims.

1. An automobile headlight, comprising aI vsaid reflector and extending through a slot in the top of said cylindrical casing, a threaded rod engaging said arm, an operating rod extending from the dashboard of the automobile and flexibly connected to said threaded rod and adapted to rotate said threaded rod, thereby sliding said reflector in said casing, a pivot support for said cylindrical casing, thereby permitting tilting of said casing upon longitudinal movement ot said operating rod. l
