.its entirety. This solution is not entirely desirable because at certain times of the day, under poor light conditions, a diminution of light transmission through the windshield reduces the visual acuity of the driver to the point of poor visibility which is conducive to accidents. Experience has shown that in the case of a glare shield in the form of a transparent tinted panel, the panel should be capable of being readily adjustable by the driver while driving so that with poor light conditions, the glare shield may be entirely or partly removed from the windshield area and with strong or harsh light conditions, a glare shield may be easily adjusted to overlie a small or a -1arge portion of the windshield area.
edge of the windshield, such visors or glare shields terminate short of the vertical central line of the windshield to provide clearance for the rear view mirror. The shortcomings of conventional visors are even more apparent in the case of the newer type of Windshields Where the windshield glass is extended further around the ends to vertically disposed door pillars.
I am well aware of the fact that attempts have been made heretofore to satisfactorily solve this problem by providing tinted, transparent panels arranged to slide into and out of the windshield area; but such arrange shield construction wherein a tinted panel is arranged 'to be easily adjusted by the driver from an extreme lowered position where it shields substantially all of the upper half portion of the windshield to an extreme raised position where it is substantially entirely removed from the windshield area.
A further object of the invention resides in the provision of an adjustable glare shield of simple and ,economical construction which with minor alterations can be applied to cars of different makes and models.
A further object of the invention lies in the provision of a combination bracket to support both the rear View mirror and the glare shield, which bracket is mountable at the top center of the windshield opening.
In the drawings:

Fig. 2 is a sectional view taken along the line 2-2 in Fig. 1.
Fig. 3 is a fragmentary view of the glare shield and surrounding structure as seen in the direction of the arrow3 in Fig. 1.
Fig. 4 is an enlarged fragmentary view of the glare shield as seen from the inner face thereof, or is a section at 44 of Fig. 1.
Fig. 5 is a sectional view taken along the line 55 in Fig. 4.
Fig. 6 is a sectional view taken along the line 66 in Fig. 4, and 66 in Fig. 1.
Fig. 7 is a sectional view taken along the line 77 in Fig. 3.
Referring to the drawings and particularly to Fig. 1, there is shown an automobile body 10 having a roof panel -12 terminating at its forward edge in a windshield header 14 which defines the upper edge of an opening for a windshield glass 16. Within the automobile, the
roof panel 12 is overlaid a headlining 18. At each side of the body 10, there is provided a front pillar 20 for a door 22 provided with a glass panel 23. The windshield glass 16 extends across the front of the automobile and around each side to the pillar 20.
The glare shield construction of this invention includes the glare shield proper, generally designated 24, and a supporting track 26. Track 26 is channel shaped in cross section (Fig. 6) and is arcuate in a longitudinal direction. A bracket 28 is provided for mounting the glare shield within the automobile. Bracket 28 is riveted to the track as at 30 and 32 and is provided with an extended portion having a pair of lugs 34 designed to be mounted flat against the header 14 by metal screws 36 at the location where the conventional rear view mirror bracket is normally mounted. Track 26 may be of the same general configuration and size for most makes and models of automobiles, whereas bracket 28 will vary to accommodate track 26 to different groups of automobiles.
Glare shield 24 may comprise a single tinted transparent panel which extends entirely across the windshield, but it also may be fashioned as shown in the drawings as two separate panels 38 which are connected together along the adjacent central edges of the glare shield. The two panels 38 are interconnected by a carriage member 40 which is preferably molded from a plastic or resin such as Bakelite. The panels 38 are mounted on a supporting base portion 42 of member 40 by a plurality of screws 44. The carriage 40 is disposed on the outer side of panels 38. A handle portion 46 molded integrally with carriage 40 projects between the adjacent edges of panels 38. At the inner face of these panels, a cover plate 48 spans the adjacent edges of panels 38 and overlies the inner face portions thereof adjacent these edges. Handle 46 projects inwardly through cover plate 48. Screws 44 extend through cover plate 48 and panels 38 and thread into the base portion 42 of carriage 40. Carriage 40 is also molded with a shoe portion 50 arranged to slidably engage within track 26. A leaf spring 52 is provided for yieldably urging shoe 50 against the inturned flanges 54 of track 26. Along the upper edge of the glare shield, there is provided a generally channel shaped metal re-enforcing member 56. It will be observed particularly from Fig. 5 that the than the carriage 40 and cover plate 48.
.material of relatively light weight. 'WOLIld have little stability as'a unit in a lateral direction, since they are secured. together and supported only 'at the central portion of the glare shield by means of the carriage 40 and cover plate 48. However, the channel re-enforcement 56 ties the panels 38 together, propanels 38 are 'arcuate in vertical section with about the sameradius as the track 26. Cover plate 48, carriage 40 and track 26 correspond with the curvature of panels 38.
Track 26 is mounted on header 14 by means of bracket 28 such that the upper portion of the track extends .adjacent'the' headlining 18 and so'thata lower portionof the track extends in a direction downwardly from .the header 14 into the area of the windshieldopening. At the upper end of track 26, there is provided a stop58 which .is removably mounted on thetrack by means of thumb screw '60. If stop 58 and thumb screw 68 are removed, then the carriage and entire glare shieldrasisembly'may be removedfrom engagement with track 26, for the purpose of washing and cleaning. A stop 62 is also provided at the lower end of track '26. .Stop 62 :includes an arm 64 which projects inwardly from the track 26. The inner free end of arm 64 supports a conventional rearxview mirror 66.
-Referring now to Figs. 3, 4 andS, it will be noted that the panels 38 are of substantially greater vertical extent Panels38 extend downwardly beyond the lower ends of carriage 40 anclcover plate 48. At the sametirne,. it 'will'be observed that the cover plate 48 extends downward-lye short distance-beyond the lower end of carriage 40. Thus/the lowermost screws 44 are secured in place to hold cover .plate 48 in clamping relation with the panels 38by means of tubular nuts 68. The adjacent vertical edges 70 ofthetwo panels 38 are spaced apart and a slot 72 extends upwardly from the lower edgeofcover plate 48 to approximately the lower end of carriage 40. The spaced apart edges 70 of panels 38 and slot 72 provide clearance for the arm 64 which forms the mirror support.
With this arrangement, the cover plate 48 imparts substantial rigidity to the two panels 38 in a lateral direction and nevertheless enables the glare shield '24to be shifted to the operative position shown in full lines in Fig. 1 wherein it overlies substantially the entire upper half portion of the windshield.
In the form of glare shield shown, each panel .38 is provided with a wing 74 at the outer end thereof which extends around and shields the side portions 76 -.of the windshield 16. In the case of an automobile provided with sloping front door pillars and wherein the windshield does not extend as far around the side of the automobile at each end, the wings 74 would be shorter.
The arrangement described herein is such that the glare shield can be shifted from the operative position In the: inoperative position,
by the sliding connection between the shoe 50 of car- 'riage'40 and the inturned flanges 54 "of track 26. Spring 52 yieldably retains the glare shield inany position along .traek'26 to which it is adjusted.
Thepanels 38 areupreferably formed from sheet plastic Normally, such panels videssubstantial lateral support, and maintains the lateral small rubber rollers 78 each of which is mounted in a bearing stand 80 fixed to the header structure at the upper edge of the windshield opening adjacent each end thereof by screws 82. The re-enforcingzmember .56 is preformed sothat thepanels38maintain pressure against .androlling contact withthe rollers 78 asthe glare shield 4 is moved upwardly and downwardly along its arcuate path determined by the track26.
Under normal conditions of driving where the surrounding light is not strong or harsh, the glare shield is retained in the inoperative position shown by broken lines in Fig. 1 where it extends substantially parallel to the headlining 18 and is substantially eompletelyremoved from the area of the windshield. When conditions of bright sunlight occur, the driver can, if he so desires, shift the glare shield to the operative position shown in solid lines in Fig. 1. With the glare shield in this position, the driver is enabled to see most of the view ahead through the lightly tinted glare shields. It will be observed that in the operative position or" the glare shield, the upper edge thereof defined generally by the re-enforcing member 56 is located slightly above the upper edge of the windshield; and the cover plate 48 and carrier 40 close the gap between the adjacent edges 70 of the panels 38 along a major portion of their extent. During the early morning or late afternoon hours, the rays of the sun may impinge directly on the eyes of the driver through the lightly tinted glare shield; and under such conditions, the glare shield panels 38 may not be suflicient to pro tect the drivers eyes from the relatively small area of such direct rays. There is therefore provided an auxiliary shield 84 of tinted transparent material which is arranged to overlie one of the panels 38 to further reduce the light transmission at the small desired area. The auxiliary shield 84 is slidably mounted on the re-enforcing member 56 of the glare shield by metal brackets 86. Thus,
the auxiliary shield 84 is adjustable laterally to a position wherein the drivers eyes are alforded the additional protection needed from the direct rays of the sun.
It will be observed from Fig. 1 that with the form of glare shield illustrated provided with the side wings 74, these side wings '74 may be designed so that in the inoperative position of the shield, shown in broken lines, these side wings will serve to shield sunlight through the glass panels 24 of the door at the area immediately to the rear of the pillars 20. This is desirable because when the sun is at the side of the car, there may be less need to maintain the glare shield in the operative lowered position. Under such conditions, it may be raised and thus utilized more for protection at each side of the car than at the front of the car.
It will be appreciated, of course, that although in the arrangement herein described, the carriage 40, panels 38 and cover plate 48 are fashioned as individual members, all of these members can be integrated into a one-piece glare shield, preferably of molded construction. Likewise, if desired, the re-enforcement member 56 may also be integrally molded with a one-piece glare shield panel by simply increasing the thickness of the edge portion of the panel.
Thus, it will be seen that I have provided a glareshield arrangement for an automobile which is of simple constnuction and still is easily adaptable to complex conditions in an automobile. The glare shield of this invention is designed to afford protection against strong light across substantially the entire upper half portion of the windshield. It is furthermore designed to be shifted readily and easily by the driver from an inoperative position extending generally parallel to the headlining ofthe automobile downwardly along the curved track 26 to a position wherein it extends generally parallel to the windshield of the vehicle. Furthermore, extremely simple friction means are provided for guiding the movement of the glare shield and for normally maintaining the glare shield in its position of adjustment. In addition,.it will be appreciated that from the standpoint of toolingfor manufacturing, economy'iseifected by designing the track and carriage assembly for use on most makes and models of automobiles and changing the design of onlybracket 28 for adapting the glare shield to different groupsof automobiles.
- In other Words, I have devised a new accessory for an automobile, a glare shield the support for which is located at the normal support for the conventional rear view mir- Ior, a glare shield which slides upwardly and downwardly between the windshield and the driver, and a glare shield having a supporting track which also supports the rear view mirror.
