DAVID Gr. KNECT, OF ALLENTOWN, PENNSYLVANIA.

HEADLIGHT @LAKE-SHIELD.

y, T all whom if may concern:

Be it known that I, DAVID G. KNECHT, a citizen of the United States, and a resident of Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Headlight Glare-Shields, of which the following is a specification.

My invention relates to improvements in glare shields for the headlights of automobiles or other similar vehicles, and it consists in the combinations, constructions and arrangements herein described and claimed.

The object of my invention is to provide a device in which the light is directed downwardly so as to illumine the road, without, however, being diminished in intensity.

A further object of my invention is to provide a device of the type described in which means is provided for preventing the glare which is so dangerous for persons approaching the machine.

Other objects and advantages will appear in the following specication, and the `novel features of the invention will be particularly pointedout in the appended claims.

My inventionv is illustrated in the accompanying drawings, in which:

-Figure 1 is a perspective view of the device.

2 is a section through the device.

Fig. 3 is a plan view of the device.

Fig. 4: is a front view, and t H Fig. 5 is an enlarged sectionthrough a portion of the device shown in Fig. 2.

In carrying out my invention I provide a ring lof standard size, this ring being E shaped 1n cross section, as shown in Fig. 5. Secured to the ring is a series of louvers such as those shown at 2, ,3, 4, etc. These lou-` vers are preferably metal plates which are arranged in substantially parallel relation. As willbe seen from Fig. 2, in the normal position of the lens plate P, the plates are inclined downwardly fromA the horizontal, the front end of one plate being substantiallyslevel'with the rear end of the plate beneath it, or in other words the louvers are inclined tothe normal to the lens plate P. The top plateeor louver'2 has ya substantially flat portion 2", a curved portion 2y on either side thereof, and flat portions 2z at the sides. The next plate 3 and the remaining plates Specification of Letters Patent. Patgntedl Dec, 31 1918.

extend slightly beyond the ring 1, as shown in Fig. 4, but have reduced portions 9 which are' arranged to enter the ring and are secured to it by riveting or any other suitable manner.

In order to hold the louvers in spaced relation, I provide at the sides, brace members 10, these brace members having portions which straddle the edges of the louvers, the portion of the brace members between the adjacent louvers being straight. The brace members l0 are soldered or otherwise secured to the louvers.

As will be seen from Fig.' 2, the upper lou-- v er 2 is the longest one and the lower louver 8 the shortest one. bviously the device might be built of any other than the number of louvers shown, without departing from the spirit of the invention. U

The upper surface of each louver 1s painted or otherwise made a dead black, with the exception of the top one, the idea being to prevent reflection of light from the upper surface. rIhe under surface of each louver is made reflecting by means of a metallic paint or by polishing the metal, or in any other suitable way.

rllhe ring 1 is made of a standard size, and it is secured to a ring 12 preferably by riveting, as shown in Fig. 5.` rIhe rings 12 may be made in various sizes to adapt them to lamps of various sizes. rIhe ring 12 is preferably hinged to the lamp housing I-I and is provided with locking members L forsecurely holding the ring 12 to the lamp housing. l l

Frompthe foregoing description of the various parts of the device, the operation thereof will be readily understood.

The' light from' the lamp M cannot shine directly ahead, because of the fact that the louvers are in the path ofthe rays.` The rays of light are deflected downwardly in front of the vehicle so that a person aproaching the headlight could not be blinded Ey the light. rIhe volume of light will be substantially the same as that given by the lamp without the delecting` louvers, but the light will be brought into the position where it is most needed and where itcannot cause dangerous collisions due to an unprotected ened, and the ring 12 with the louvers may be swung on the hinge K so as to permit the cleaningof the lens P.

l claim:

1. A headlight glare shield 'comprising a ring hin edly secured to the headlight housing, a p urality of louversl secured to said ring, all of said louvers extending forwardly from the headlight and being inclined downwardly, and means for spacing the front ends of the louvers apart and holding them in spaced relation, the front end of each louver being substantially on a horizontal level with the rear end of the louver below it.

2. A headlight glare shield comprising a ring hingedly secured to the headlight housmg, a plurality of louvers'secured to said ring, all of said louvers extending forwardly from the headlight and bein inclined down# wardly, means for spacing t e front ends of the louvers apart and holding them in spaced relation, the front end of each louver being substantially on a horizontal level with the rear end of the louver below it, the upper surface of all the louvers except the top one, being black, and each louver having a lower reflecting surface. i

3. A headlight glareshield comprising a ring hingedly secured to the headlight housing at the top thereof, a plurality of louvers secured to said rin said louvers extending forwardly from t e headlight and being inclined downwardly, means for spacing the front ends of the louvers apart and for holding them in spaced relation, the front end of each lover being substantially on a horizontal level with the rear end of the louver below it, the upper surface of all of the louvers except the top one, being black, and each louver having a lower reflecting surface, and locking means for holding the ring in position on the housing.
