NONGLARE AUTOMOBILE LAMP SHADE.

Application i1ed April 7,

This invention relates to a shade for the headlamp or" a motor vehicle, the general object of the invention being to provide a shade so constructed that it will prevent the 5 rays ot' light 'from the lamp from blinding drivers of approaching vehicles without interfering with the proper illumination of the road, with adjustable means for attaching the shade to the lamp so that the shade can be used on different kinds and makes of lamps.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specilically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a front view showing the shade attached vto a lamp.

Figure 2 is a plan view of Figure l.

KV Figure 3 is a section on line 3--3 of Figure l, with the lamp omitted.

ln these views, the numeral l indicates the shade which may he formed of any suitable material, either opaque or translucent, said shade litting over the upper part of the front et the lamp and curving downwardly and forwardly to al point in front of the lamp. The front of the shade is formed with a centrally arranged beak 2 which extends downwardly and forwardly and this beak and the central part of the shade extend in front of the bulb ot' the lamp so as to prevent the central rays of light from the bulb from blinding drivers ot' approaching cars. The sides of the beak are connected with the front of the shade by the sharply defined curved portions 3, and these curved portions permit some of the rays of light from the lamp to illuminate the sides of the road and prevent shadows being formed by the beak. Thus the central rays from the lamp bulb are 1928. Serial No. 268,197.

split by the beak and such rays are deflected downwardly and to the sides of the road.

The device is preferably provided with strengthening ribs 4 which extend transversely and if desired, the device may be formed in sections. with the sections united at the. ribs, though the drawing shows the de vice termed of one piece.

A rod 5, bent into bow shape7 has its ends threaded and passed through perforated lugs 6 at the sides ot' the rear part of the shade, with nuts 7 on the threaded ends for clamping the rod and shade to the front part of the headlamp, such as shown at A. A tube 00 S of rubber or the like is placed on the rod to prevent the rod from marring the lamp.

It is thought 'from the foregoing description that the advantages and novel features oi my invention will be readily apparent.

t is to be understood that may make changes in the construction and in the combination and arrangement oit the several parts, provided that such changes fall within the scope of the appended claim.

lV hat I claim is A shade ttor a headlamp of substantially semi-circular form in cross section and curving downwardly and vforwardly from its rear to its front, with its Yliront edges substantially straight, a downwardly and forwardly extending beak centrally arranged at its 'forward end. the edges of the beak being connected with the front of the shade by sharply defined curves whereby some of the rays of light trein the lamp will illuminate the sides ol the road and prevent shadows being formed by the beak, a rod bent into bow shape for embracing the lower part of the headlamp and having its ends threaded, perfo- 85 rated lugs at the lower edges of the rear of the shade through which the ends of the rod pass, nuts on the threaded ends and a tube of resilient material on the rod.

ln testimony whereof I aflix my signature.

MRS. ELLA R. HOUK.
