Application filed November 9, 1925.
This invention relates to headlights for automobiles and the like and particularly to means for deflecting the light, and the primary object of the same is to provide a deflecting attachment that may be readily applied to the interior of the reflector without materially modifying'the structure of the ordinary form of headlight embodying a parabolic reflector, andwhereby light rays projected from the headlight may be modified to such an extent as to eliminateobjectionable glare and yet give sufficient light with relation to the roadway to enable a driver to be guided in the operation of the machine.
A further object of the invention is to provide a deflecting attachment for a headlight or the like which may be applied within the headlight atone operation and positioned toeifect control of the projected light rays as may be desired, and particularly the usual upwardly flaring light rays which are so objectionable to pedestrians and those operating machines progressing in a. direction opposite to that of the machine carrying the attachment.
With these and other objects and advantages inview, the invention consists in the preferred construction and arrangement of parts which will be more fully hereinafter described and claimed.
In the drawings:

Serial No. 68,020.
Fig. 5 is a detail perspective view of a portion of'the side of the frame opposite that shown by Fig. 4 and particularly illustrating the cooperating means for actuating the shutters.
Fig. 6 is a front detail elevation, partially broken away, particularly showing-the mutilated gear disks and levers and the spring in the front of the casing by any preferred means. ,The headlight is substantially of well known construction, and the only modification necessary in applying the improved deflecting attachment 1s toform openings 9 and 10 in the lower portion of the reflector 6 and easing 5 for movement therethrough of operating means for the improved attachment.
The improved attachment consists of a U- shaped frame 11, which is secured at the center of the top member 12 and at the lower ends of the side members or legs 13 by bolts or analogous fastenings 14 to the reflector. The lower part of the frame is fully open, as at 15, to allow unrestricted movement of the lower part of the deflector mechanism in a downward direction. The improved attachment is disposed in advance of and in any suitable position within the reflector 6, in the present instance the attachment being elevated to its maximum extent within the reflector, but it is obvious that it could.
be lowered to obtain a desirable modification of the projected light rays. Between the legs 13 of the frame 11 a plurality of shutters 16 and 17 are pivotally mounted, the shutters 16 being similar in construction and the lower shutters 17 somewhat varied or provided with means which will shield or diffuse a part of the lower projected light rays. All of the shutters 16 are movable from a normal horizontal position upwardly at a rearward angle of inclination as shown by Fig. 3, and'the lower shutter 17 is re versely movable in a downward and rear- Ill lie
the formation of the 'loi'er shutter ward angular direction. The shutters consist of base plates 18 with side flanges 19 at right angles to the said plates, pivot-s 20 being inserted through the side flanges 19 and secured to the 13 of the frame 11. The lower shutter 1'? comprises a flat base strip 21 with upstanding end ears or pivot flanges 22, which are connected by pivots or pivot fastenings 23 to the lower portions of the legs 13 of the frame 11, and to the lower side of the flat strip 21 a holding strip is secured having transverse corrugations or downward bends 25 on opposite sides of the center thereof. to facilitate the insertion and retention between the flat strip 21 and holding strip 2 1 of a deflector plate 26, which may be of any material adapted for the purpose, such as frosted or colored glass, mica, or prismatic glass, to serve as a softening or diffusing; means for the bright projected rays in'imediately in front of the light source or electric incandescent bulb 7. The shuttersle are reinforced by the formation of the flanges at the ends thereof in addition to the function of the said flanges of serving as means for pivotally connecting them to the legs 13 of the frame 11. The shutters 16 are shifted as a unit through the medium of a link 27 pivotally connected thereto, the lowerend of the said link being also attached to a lever 28 having a disk head 29 centrally secured to the one end pivot 20 of the lower shutter of the group of shutters 16. The disk head 29 has a mutilated gear structure, or the periphery thereof is partially toothed, as clearly shown by Fig. 1. The lower end of the link 27 is pivotally connected to the lever or lever arm 28 of the disk head 29 at a distance inwardly from the rear free end of said lever, and as a combined reinforcing and adjusting means,
an upwardly projectingarm 31 is provided and has a vertical slot 32 therein which is engaged by a header. screw 33 also secured to the lever 28. The arm 31 is fixed to the bottom plate 18 of the lowermost shutter 16,
and this lowermost shutter has the central iortion of its bottom plate 18 arcuately rccessed, as at 3 1, to clear the forwardly projecting portion of the bulb of the light source '7. The one :pivot which connects the one end ear of the strip 17 comprised in v also serves as a fulcrum means for a disk head 35 l'ia'ving a lever or lever arn'i 36 extending re wardly therefrom and serving as the mam operating instrumen'tality or actuating means for moving the entire group of shutters. The disk uead 35 has its periphery par'tially toothed, as at 37, the teeth and 37 ot the two disk heads 29 and 85 being in continual mesh and in effect serving as gear teeth segments. To return the disk head and its lever or lever arm 361:0 normal position subsequent to operation and release the lev r or leyer arm 36, the opposite QX- tremity of said spring being held fixed in a clip 1-0 secured to the outer side of the adjacent leg 13 of "he frame 11, as clearly shown by Fig. 1'. The depressions 25 on the opposite sides of the center of the holding strip 2 1 for the deflector plate which may be of opaque formation or frosted, colored or prismati hereii'ibefore indicated, serve particularly for convenience in applying the fastening means tor said plate to the strip 21 of the lower shutter 17. The bottom plates 18 and the end flanges of the shutters 16 are formed of suitable metal and polished or otherwise brightened to render them effective as subsidiary reflecting devices when the shutters 16 are in normal horizontal positions, and likewise the members of the frame 11 may be brightened or polished or provided with reflecting surfaces so that they will 'ceact with the shutters 16 as reflecting means.
The motion of the lower shutter is transmitted at its end opposite that to which the disk head is connected by means of a mutilated gear disk d0, secured'to the pivot device at the end of the strip 17 opposite that to which the disk head 35 is connected, and this mutilated disk or gear is held in continual mesh with a segmental gear ii on the forward end of a lever 1-2, pivotally held between adjacent end pivots of the lower shutter 16, the lever or lever arm 42 extending rearwardly from the said toethec segment and connected to the outer side of the end flange 19 of the lowern'iost shutter 16, to assist in regularly operating the shutters 16. l
The operating means for the. attachment preferably consists of a pull wire or small rod 15, having its upper end attached to the rear extremity of the lever or lever arm and passed downwardly through the openings 9 and 10, respectively formed in the reflector and casing, the lower end of this red having a shock spring 16 connected thereto and interposed 'therebetween and the lower extremity of an actuating wire 4:6 which is passed through a coiled tubular member extending upwardly at a rearward angle of inclination and terniiinati'nfl,- adjacent to the steering post within the body of the automobile as shown. the upperend of the wire 16 being movably connected to one end of a lever 48, pivotally attached at an intermediate point to the steering post 1 9, the said lever having a handle for actuatin rthe same. The handle extremity of the lever 48 is normally elevated and withineo'nvenient reaching distance of the steering wheel 51.
l UK) TZU The operation of the improved attachment is very simple, and consists in pressing the handle 50 of the lever 48 in a downward direction and thereby pulling upwardly on the wire 46 and drawing downwardly on the shock spring 46, which in turn exerts a downward pulling action on the wire 45 and a depression of the lever or lever arm 36. The downward movement of the lever or lever arm 36 rotates the disk head 35, and through the gear teeth or segmental gear 37, the gear 30 effects a reverse movement of the disk head 29 and an elevation of the lever or lever arm 28. which in turn transmits movement through the link 27 to the shutters 16 and a portion of the lower light rays and acts as a deflecting or diffusing plate for the said lower light rays that are projected from the light source. By this means the glare at the center of the headlight is eliminated and softened or diffused but at the same time the open spaces above the top member 12 and outside of the legs 13 of the frame and also below the limit of projection of the plate 26 permit light rays to be projected by the reflector through the lens and particularly at the side and lower portion of the headlight sufficient to guide the driver in the operation of the automobile or machine." After the improved deflecting attachment as a wholehas served its purpose by disposing the upper and lower shutters in reverse angular positions as just explained, the primary actuating lever on the steering post is released and the spring 38 instantly restores the shutters to normal position, permitting light rays from the light source to be projected therebetween and through the frame supporting said shutters. The spring 4:6 absorbs any shocks that may be present during operation of the attachment.
The improved light controlling or defleeting attachment as a whole will be found very advantageous and effective in its operation, and it is to be understood that changes in the proportions and. general dimensions of the several parts may be adopted at will to accommodate headlights of various sizes.
