AUTOMOBILE HEADLAMP.

applmationaiea octgber 11, 1924. serial No. 742,971.

To all whom t may concer/n.:

Be it known that I, MELvTN A. FLAU'rr, a citizen of the United States, residing at Waynesboro, in the county of Franklin and State of Pennsylvania, have invented cer tain new and useful Improvements in Automobile Headlamps, of which the following is a specification. U

The present invention relates to means for controlling or directing the rays of light from the head lamps offautomobiles and the like, andthe object is to provide a simple structure of this character, preferably in the form 'of an attachment that can 1 5 be applied to the standard type of head lamp and will insure the light therefrom` properly directed and thev glareelimi-- being nated.

In the accompanying drawings:

Figure 1 is a horizontal sectional lview through the preferred embodiment of vthe invention,

Figure 2 .is a rear elevation ofthe attachment and the glass to` which it is applied, l

on the line 3-3 of Figure 2,

Fi re 4 is a detail erspecti've view showing the screw mountlng for the `wall adjusting means. v

In the embodiment disclosed, a wellknown form of lamp is shown and is designated generally by the reference numeral 5.

' In it is located the usual electric light bulb 6. The `glass for the lamp is shown at 7.

Crossed supporting arms or bars 8 are provided as a mounting for the light-icontrolling or directing. means. vThese arms terminate in hooks 9 that are .engaged over diametrically opposite edges of the glass 7. 4o Mounted on the arms at their crossing point is 'a series of walls, one within the other,

these walls preferably being formed by a strip'A that is coiled, the convolutions '10' Figure 3 is a detail sectional view taken width it will be noted that as the outer edge of the strip rests against the glass the inner edge extending farther and farther from the same forms in the rear end of the light directing means, a recessed seat that receives the front end of the electric lamp 6.

The coil is surrounded by an outer wall ring .12 having diametrically opposite lugs in the form of nuts 13 that are located in openings 14 formed in one of the supporting bars 8. Screws 15, journaled inthe said bar, have' threaded engagements with said lugs.

In the inner sides of the walls are formed openings 16 which are aligned vand there-- fore allow the light lfrom the lamp 6A to pass inwardly and downwardly, `the two `amps producing along the road diagonal.

lbeams ofliofht as illustrated in Figure 1.

Preferably the inner and outer faces of the 'coiland'the inner face of the surrounding wall 12-are bronzed, as a consequence of 7 5 which the light reiiected inwardly from 'said walls'is toned down u on the reflector -and is refiected outwardly 1n the form of a glow .which vgives splendid illumination but so entirely eliminating the glare. The wall 12 ismade adjustable so that its rear edge may be paced in or behind the line extending from the filament of the lamp to the inner edge ofthe bezel or exposed portion of the glass 7. By this adjustment the device can be properly fitted to the particular lamp so that no rays will escape directly from the lamp through the marginal portions of the glass and the entire structure may be made to emit the glareless glow above indicated.

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, without further description and it 4will be understood that various changes in the size,

shape, proportion and minor details of construction lmay be resorted. to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

1. A light shield for head lamps, comprising a series of walls formedby a coiled strip, the convolutions of which are spaced "apart, the inner ortion of said strip and the inner convolut1ons formed thereby being ,narrower than the outer portion and outer volutions that increase in width toward the outer portion of the shield, and said strip having its convolutions increasing in dis-- tance apart from its inner to its outerend.

3. A light shield for head lamps comprising a series of walls, one Within the other leaving open-ended spaces, the-inner of said walls being Vof less Width than the outer,

forming a lamp-receiving recess, the outer of said walls having aligned openings therethrough to permit lateral direct` rays from a lamp placed in the recess.

4:. A light shield for head lamps, comprisi ing a series of walls formed by a coiled strip, the convolutions of which are spacedV apart, said strip gradually increasing in width from its inner to its outer end, forming a lamp-receiving recess, said strip having its convolutions increasing in distance from its inner to its outer end, the outer of said convolutions having aligned openings therethroughy to permit lateral direct rays from a lamp placed in the recess.

5. A light shield for head lamps, comprising a series of walls, one within theother, leaving open-ended, light emitting spaces, an outer wall surrounding the said series, and means for adjusting said wall with respect to the series of walls. w

6. A light shield for head lamps, comprising a coil forming a series of walls, one within the other, leaving open-ended, light- .emitting spaces, an outer wall ring surrounding the coil, and means for adjusting said Wall withI respect to the series of walls.

7; A light shield for head lamps, comprising crossed supporting bars, a strip in the form of a coil located at the' juncture of the bars, the strip increasing in width from the `inner towards the outer end, a wall ring surrounding the coil, and a screw adjustment means between the. wall ring and one of the su porting b ars `forA holding said ring in di erent positlons with respect to the coil.

'In testimony whereof, I aiix my signature.

MELVIN A. FLAUTT.
