HEADLIGHT.

Application filed July 13, 1923. Serial No. 651,209.

To all whom it may concern:

Be it known that I, FREDERICK Brznrom), a citizen of the United States. resid ng at Stratton. in the county of Hitchcock and State of Nebraska, have invented certain new and useful Improvements 1n Headlights, of which the following is a specificavinvolving the objectionable glare of headlights and the blinding of motorists coming toward the lights.

Another object of the invention is to provide a lens in which the light rays normally horizontal or directed downwards will be given passage without interference but wherein those rays reflected upwards will be absorbed and cut off.

A further object of the invention consists in securing the above-described results in simple, inexpensive and compact construction such as will conform to the standard structure of vehicle lamps and may be subst-ituted for. the lenses thereof.

With the foregoing and other objects in View, the invention will be more fully .described hereinafter, and will be more par ticularly pointed out in the claims appended hereto.

\ In the drawings, wherein like symbols refer to like or corresponding parts throughout theseveral views,

Figure 1 is a' longitudinal section taken vertically along the medial line of Figure 2.

Figure 2 is a front elevation or face, the glass 14 being removed.

Figure 3 is a plan view of a fin orsanded.

member.

Figure 4 is a plan view of a number of incised lower fins.

Figure 5 is a section of a fin.

Figure 6 is a longitudinal section-of'a.

modification of the device.

Figure 7 is a plan view of a modified fin. Figures 8 and 9 are sectional views of modifications of fin constructions.

In the drawings the numeral 10 indicates a metal shell or housing 11 a reflector of polished silver plated metal, which is substantially semiglobular. in shape, provided with an electric light bulb-12 adapted to be connected with a battery (not shown).

The parts are well known in present lamp construction and additionally a metal ring 13. is usually provided with which to secure the glass or lens in place. However no glass or lens, at least of the usual character is employed in the present case and the ring 13 subserves the function of holding. the glass bulb or globe 14 and the glare shield member as now described. p

In Figure 1 a semi-globular glass 14 is employed, for the purpose of preventing the elements from entering the headlight.

The new device or shield is semi-globular in contour and consists of a metal ring 15 having a flange 16 adapted to be secured by the locking ring 13. The upper portion plan as shown in Figure 3 and are soldered or otherwise suitably secured to the ring 15. These fins are treated. as follows: In Figure 5 a section is shown. The numeral 21 indicates a shellac coating on the fins which are first dipped into a bath of this material and then dustedwith sand 22 for purposes later described.

The lower fins need not be so treated unless a uniform appearance .is desired and these fins, numbered 23, to 27, are segmental in plan as shown in Figure 4. Such fins are mounted on the ring 15 in a manner so that, preferably, they radiate from thelight bulb 12 as a common center, or fanw1se. The fins are provided with elongated slots 28 through which beams of light are adapted to be projected as later explained.

The fin 25 or the other may have one or more slots 28. Any number of fins may be employed according to the size anddiameter of the headlight and according to how fine a division of the space is re uired.

In Figure 6 is shown a m ification. The ring 15 is wider and provided with an extension fastening ring 13' for securing the flat lass 14. The fins 19 are rectangular in p an as shown in Fi re 7 and'coated with sand :22, The 01*. 29* are beveled for accurate fitting and soldering to the ring 15 which may also becoated with sand 22 if desired as shown near the top of Figure 6. The lower fins 27, 26, 25, 24' and 23' are similar to Figure 1 except that they are rectangular in plan. An desired number ,may be employed having s ots 28'.

ates in the same manner as that shown in Figure 6 and therefore but Figure 6 will be described.

In Figure 5 the numeral 32 indicates a ray ,of light which is projected against the fin 19 at a tangent angle, where it strikes the grain of. sand 22 which functions as a stop, bar or detent in a manner to absorb or obstruct, the further reflection of the ray as indicated by the dotted line 33. If any' of the light is not killed at 22' but is deflected upward as at 33, such ray of light will be of course weaker.

The irregular indentations projections, lumps or the like as shown in Figure 8 at 30 serve the same purpose. Also the regular wave-like corrugations 31 (Figure 9) do the same, but not as well. i

In Figure 6 the ray of light 34starts from the bulb 12. and is deflected and reflected at 35 to the fin at 36 where it is partly or wholly killed or again deflected to 37 where it is totally minimized in a manner so that it will not'project as at 38, at an up-' ward angle to strike and blind an approaching driver.

A ray such as 39 may pass the fins, at a horizontal with the ground. Such ray will not project upwardly.

Direct rays such as 40 may pass the lower fin but will be directed to the ground. A

ray such as 41 may pass through the elongated slots of the lower fins and do useful work. A ray 42 or 43 will be trapped and prevented from an upward slant, and be projected to the ground in front of the auto mobile for useful work.

I do not wish to be restricted to the size, form, and proportions of the various parts, and obviously changes could be made in the construction herein described without departing from the spirit of the invention, it being only necessary that such changes fall Within the scope of the appended claims.

What is claimed is 1. A device as described comprising a light source, a reflector, a series of spaced apart substantially horizontal fins disposed in front of the upper portion of the reflector and having corrugated surfaces, and a second series of fins disposed in front of the lower portion ofthe reflector and being inclined from the reflector downwardly and outwardly, certain of said inclined fins having single slots therein and certain other of the inclined fins having a plurality of slots therein.

2. A device as described comprising a light source, a reflector associated therewith. a ring extending about the edge of the re-. flector, means to hold the ring in place, a hood carried by the upper end of said ring, a plurality of fins secured to said ring and extending theieacross in a substantially horizontaldirection, said fins being spaced apart and being elongated in the direction of the path of the light rays, said fins being provided with light-absorbent surfaces, certain of said fins beinginclined and provided with slots, the slots in one fin adapted to register into substantially horizontal direction with the slots of adjacent fins.

In testimony whereof, I have aflixed my signature in presence of two witnesses.

FREDERICK BEDFORD.
