AUTOMOBILE HEAD LAMP.

a mauonm a March, 1924. Serial 80.102391.

To all 1071 am it may concern:

, Be it known that I, MELVIN A. ZFLAUTT, a citizen-of the United States, residing at Waynesboro, in the county of Franklin and State of Pennsylvania; have invented certain new and useful Improvements in Automobile Head Lamps, of which the following is I a substantially horizontal direction, thereby a specification.

The-present invention relates to means for controlling or directing the rays of light from the head lamps of automobiles and thelike, and the object is to provide a simplestructure of this character, preferably in the form of an attachment that can be applied to the standard type of head lamp and will insure the light therefrom being confined to eliminating the broad glarethat ordinarily emanates; from lamps of this character.

In the accompanying drawings Figure 1 is a. ;vertical sectional view through the preferred embodiment of the invention,

, Figure 2 is a front elevation of the same, the structure being illustrated as mounted ona head lam Inthe drawing, the head lamp is desig nated by thereference'numeral 3 and includes a reflector 4;, in front of the central portion of which is mounted an ele tric. lamp 5. The usual ring or rim for holding the glass in place is shown'at 6. In the embodiment disclosed the glass is supplanted by the light controlling means.

.. This means comprises a cylindrical housing 7 open to the passagegof light there through,'but preferably havinga glass 8 across its front end.

'- ring or rim 6 in a manner well understood to those skilled in the art. Within this housing is a strip of any suitable opaqpe material, formed into. a coil 10. The space between the whorls of the coil increases from the center or inner end of the strip to the outer end of the same. This spacing is preferably maintained byright angular rods 11 passing through the coil. It will also be noted by reference to Figure 1 that the strip increases in width from its inner end or the center of the coil to itsouter-end.

The lower side of the housing 7 is preferably provided with alight emitting open- .ing 12 and the whorls of the coil on their y Y e rear end of thehousing has an outstandingannular flange 9 its outer end.

line with this-o ning. As a consequence (a beam of light Wlll be emitted forwardly and downwardly upon the roadway. I Bythis construction, the widely divergent.- rays of light ordinarily eoming from a head lamp 'are, prevented and a relatively straight-ahead beam is projected from the lamp. The continuously increasing width of the walls formed by the coils is also of importance'. Obviously the rays of light projected from the reflector can have limited diagonal paths determined by the space .be-; tween the walls. This furnishes a flood of light ahead, but as the point of vision of", 79 said lamp, for. example by an approaching automobilist, lessens, the width of the flood of light decreases so that the vision of a' person approaching is not blinded by the lght but the path of the latter is wholly at one side .as two cars come within passing distance and the lights do not interfere. In addition provisionis made for illuminating the roadway in front of the automobile carrying the lamp. It will be noted that'the structure may be in the form of an attachment that can be readily applied to the standard lamp.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will. be apparent to those skilled in the art, withoutfurther description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from 1 the spirit or'sacrificing' any of the advantages of theinvention.

What I claim, is 1. A light-shield for head lamps and the like comprising a, housing open at its ends to the passage of light, and a light-controL ling strip in the form of'acontinuous 0 en coil located within the housing, said s rip increasing in width from itsunner to its outerend. i

2. A light-shield for head lamps and the like comprising a housing open at its ends to the passage of continuous light, and a light-controlling strip in the form of an open coil located within the housing, the

- space between the whorls of the coil increasing toward one end of said coil and said strip increasing in width from itsinner to no 3L-'A light-shield for head lamps and the like comprising a housing'having its ends open to the passage of light, a coiled lightcontrolling strip in the housing, said strip 5 increasing in width from its inner towards its outer end and the space between the whorls also increasing from its inner towards its outer'cnd, said housing and a portion of said strip having alined cutaway portions to permit the, lateral passage of a 1D beam of light. s

In testimony whereof, I afiix my signature.
