HEADLIGHT.

Specification oi' Letters Patent.

Patented July 13, 1909.

1908; Serial No. 428,863.

T 0 all whom it may con-cem:

Be it known that I, CHARLES L. BnTrs, a citizen of the United States, residing at New York, borough of Brooklyn, in the county of' Kings and State of New York, have invented a new and useful Improvement in Headlights, of which the following is a s ecification.

This invention relates to t iat class of headlights which are used on vehicles, articularly automobiles, and has for its oliject to provide such headlights with means for quickly and conveniently changing the forward reflection of light so that the full refleeting power can be had when required, for instance, when running on a darli road, while the reflection can be quickly diminished when running on a lighted street, where the full reflection is objectionable by reason of the blinding glare.

In the accompanying drawings: Figure 1 is a rear elevation parti in section in line 1--1, Fig. 2. Fig. 2 is a ongitudinal section showing the rear reflector in its normal posi tion. Fig. 3 is a sectional elevation showing the rear reflector tilted. Fig. 4- is a fragmentary longitudinal section of the lower portion of the rear reflector and connecting parts, on an enlarged scale. Fig. 5 is a vertical transverse section on line 5*5, Fig. 4.

Like reference characters referto like parts in the several figures.

A represents the shell or casing ofthe headlight which maybe of any desired formand which -is shown as comprising a horizontal cylindrical body l0, a flaring front 11 and a closed back 12.

13 represents an acetylene burner oi other suitable source of light arranged within the body 1() of the shell in any suitable manner.

14 represents the front glass or lens and 15 the front reflector secured within the front ortion of the shell and having the form of a orwardly flaring truncated cone.

B represents the rear reflector arranged within the rear portion of the shell and comprisiiiga shallow concave glass reflector 16 -and an annular metallic frame 17 in which the glass is secured, This reflector is suspended within thesliell by means of a transverse hinge or pivotal joint 18`which is ar- 4ranged at the top of the reflector' and on which the latter can be adjusted with a forward or backward pendulous movement, so that the reflector can be placed either in its normal upright position, represented in Fig. 2, or obliquely, as represented in Fig. 3.

fixed front reflector 15, while in the oblique position the axis of the rear reflector is deiiected. downwardly.

The rear reflector is provided at its lower end with a threaded screw stem 19 which'extends downwardly through a longitudinal slot 20 in the shell and which isA rovided with a screw nut 21 which can be tightened against the under side of the shell for securing the reflector in its adjusted position. The rearward movement of the reflector may be lirnited by a stop 22 secured in the shell. Upon releasing the screw nut the reflector can beshifted from one position to another and when the reflector has been shifted it is readily secured in the desired position by tightening the nut.

In the normal position of the movable rear reflector its o tical axis is in line with the optical axis o the fixed front reflector and a owerful forward reflection is secured, which is resorted to when necessary, as for instance, when ruiming on an unlighted road. -Upon tilting the rear reflector, the latter is rendered' ineffective to a large extent and the forward illumination is furnished mainly by the direct light of the flame or'other source of light and the front reflector, which illumination is sufficient for running on lighted streets or roads. Either the full forward illumination or the partial illumination can be quickly secured by means ofthe adjusting mechanism under control of the driver.y

I claim as my invention:

ing and a source of light arranged therein, of a movable reflector hinged at one end to swing forwardly and backwardly at the o osite free end, a stein extending from t e flee end of the reflector through the casing,

In the normal position the optical axis of j the rear reflector coincides with that of the,k

l. The combination with a headlight casl reflector supported et the to and means on the outer side ofthe easing for securing the stem in position, substantially as set forth.

2. The combination with a headlight oasi 'having a longitudinal slot, and a source ght arranged in seid Casin of a movable y a transverse hinge and provided at the ovver end with e screw stem which projects through said slot and is provided on the under side of the casl0 ing with a clamp nut, substantially as set forth.

Witness my hand in the presence of two subscribing Witnesses.
