LIGHT DIFFUSER FOR HEADLIGHTS.
APPLICATION FILED MAR. T. I9I8.

CHARLES HQ MUCKENHIRN, 01F DETROIT, MICHIGAN.
LIGHT-DIFFUSER FOR HEADLIGHTS. I
Specification of Letters Patent.
Patented Dec. 1'7, 1918.
Application filed March 7, 1918. Serial No. 221,019.
To all whom it may concern:
Be it known that I, CHARLES H. MUCKEN- HLRN, citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Light-Diffusers for Headlights, of which the following is a specification, reference being had the front or lens portion of a head light of glass, and whether plane or provided with projecting parts, there is a constant danger of breaking the same both because of vibrations or jars, and the binding action of the clamping means thereagainst, owing to the lack of capability of the glass to inherently yield.
it-h the foregoing in mind I form my front or diffusing device of a flexible material such as pyroxylin, celluloid, or a celluloid-like material which will be flexible throughout enabling the device to give or yield around its clamping marginal portion, and reinforcing th central portion of the body by what may be variously disposed projections or bulges which will also act as light dilfusing elements.
The device. will be inexpensive and of inconsequential weight, thus lending itself to the many uses for which it may be formed and where the supporting or mounting thereof before a lamp will not require material consideration.
Preferably the device is formed of two thicknesses superposed and securely fastened together so that one layer or thickness will additionally strengthen and support the other. all giving'an increased thickness or body to the whole, and also, in motor vehicle service, giving a backing to the layer or thickness used as the exposed front.
In some cases, where desirable for ornamental or color efi'ect the-layers may be different and for example, one layer may be perforated to permit of a variegated color effect, as differentiated from a solid color where but one layer is colored, or where both are colored and merge to combine to produce a third ultimate solid effect or color.
The details in construction and arrange ment of parts will be more apparent from the specific description hereinafter contained when read in connection with the accompanying drawings, forming part hereof, and wherein the preferred embodiment of the invention is illustrated.
In the drawings:
Figure 1 is a vertical sectional view showing my device applied to an ordinary automobile head light.
Fig. 2 is a sectional view of the device showing the layers before they are secured together as a unit.
Figs. 3 and 4 are respeetively'front and rear views of the bulged or reinforced layer of the device, and
Figs. 5 and 6 are respectively front and vertical sectional views of another embodiment of the invention.
Referring more specifically to the drawings, and for the present with reference to the first f our views, wherein like reference letters refer to the same parts in the several views, A represents an ordinary head light and B the lens clamping means thereof which may be of any well known type, not necessary to be particularly defined herein.
C represents the outer layer and D the inner layer of my improved lens or light diffusing device. the same being entirely fo rr..ed of a flexible material such as pyroxylm, celluloid or celluloid-like material. The
two layers are secured together, by appros,
priate cementitious material such as amylacetate, or otherwise, to constitute a firmly united whole or entity. The outer sheet or layer, in this instance intended to serve as the exposed outer face of the lamp is smooth so as to afford no obstruction for the accumulation of snow, dirt, or similar obscuring elements, but the inner 'layer is provided with a central bulge E and a series of, as here shown, radial elongated pear shaped bulges F extending entirely around the center and converging toward the center, to serve the double function of diffusing the light, and of strengthening the flexible relatively light and thin material. Other shapes and designs may, however, obviously be employed. These elongated pear shape bulges increase in depth toward the surrounding liio hulges, ta
marginal. portion G which is left smooth for engaging Within the clamping means the outer terminal portion of said bulges represented at H, rounding laterally in both ilireotions as Well as longitudinally.
The inner layer constitutes an efficient backing for the forward layer 1'30 resist inward henrling pressures or slrains and the outer tapering oi the bulged portions near the sevuring nmrginal portions e eitlererl in connection with the llexilile, yielclahle nafure thereof, will without breakage should clamping means or other obstructions Contact the some.
