Patented July 21, 1931 PATENT OFFICE LONG-WORTH B. LEWIS, OFZMONTROSS, VIRGINIA GLARE SHIELD Application filed August 19, 1929. Serial No. 386,887.

rI`his invention relates to Yanti-glare shields for motor vehicles and more particularly to a device of this character havingkmeans fork electrically controlling the same.

s The principal object -oi' this invention is to provide a glare shield operated by a* single means whereby the shield will be folded away from the line of vision of the driver and into the line of vision when so desired. At the present time there are many ant1-.

Another object is to provide means for operating the anti-glare device withoutdiverting the driver-trom his task of operating the ca r. f

Other objects will be disclosed in the speciication and drawings, which are made a part of this application.

In the drawings- Fig. 1 is an elevation illustrating the use of my device as attached to an automobile;

Fig. 2 is a front elevation, partly in section, of my device in shielding position;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2; y

Fig. 4 is an end elevation partly in section,

Fig. 5 is a vertical section taken intermediate the device and showing the device in raised inoperative position;

Fig. 6 is a similar View taken adjacent the locking ratchet to illustrate the normal locked position of the device; 1

Fig. 7 is a vertical section online 7-7 of Fig. 2 through the hinge rodl showing the .5o inoperative position; andk y f ,tion in a series of movements. yarms 11 are provided with pins 14 to slide showing the shield in partly raised position;v

Fig. 11 is a wiring diagram showing how the device may be hooked up to the battery of a vehicle and Vshowing two switches,` one of which controls the live large magnets which operate to raise the device to a horizontal position.

Referring to the drawings, in which like parts are designated with similar numerals, numeral 1 designates an anti-glare device 4having a lframe 2, containing amber or colored glass 3. Extending through the upper portion 1 of :trame 2 ,is a hinge pin 5. The frame 2 is adapted to pivotally swing from the hood 6, the hood thus being attached above a windshield in proper position. The ends 8 of said hinge pin 5 are preferably squared, to be received in square bearing openings 9, in ears 10 which are fixed to the rear of the glare shield frame 2 in i order that the turning of the pin 5 may in turn operate the frame 2. The hinge pin V5 has mounted thereon at spaced intervals,

radially extending arms 11 with contact spring members 12 fixed to the ends of said arms `11.V The radial arms 11 are spaced a predetermined distance apart for the purpose ofraising the shield 1 from a vertical operative position to a horizontal inopera- 'tive position.' A. plurality of magnets 13,

are mounted in the hood 6, in position to attract thefradial contact members 12 in successionso'that the shield 1 is Aelectrically and automatically raised from a vertical posi- The radial in spaced slots 15 cut into the hinge pin 5 lsothatthe proper lost motion is provided to permit the successive movements of the radial arms 11. A pawl 16 and ratchet 17,

mounted on thehinge pin 5, lock the shield 1 in an inoperative position; the pawl 16 being forced into engagement with the ratchet 17 by a spring 18. A. magnet 19, placed adjacent the pawlf16 will retract the said Vpawl`16 and 'free the ratchet 17, upon being energized. 'A switch 20, of the progressivetypefis mounted on steering wheel 21. The progressive switch has a terminal 22, which is connected up with the magnet 19, which controls the pawl 16 and ratchet 17 and a second terminal 23, placed beyond the terminal 22, which controls ive large magnets 18, which attract the radial arms 11.

As actually operated, the switch 2O will be pressed until it contacts with terminal 23, thus closing the circuit and energizing the ive large magnets 13'. The radial` 11` five in number, are arranged afan-shape'- so that the arm nearest perpendicular willbe directly opposite an energize-d manet.`

If I divide the 9()o of theA distanc'e'which represents the distance from the horizontal" position of the shield 1, to the perpendicular position, by 5, I find that lthere w'i'll" be 18 between each radial ar m 1 1 and 18O between the: uppe'rinostarn'i 11 and thel magnets The magnet oppositeA the uppermust strong 'enou'gh to attract the uppermos f but-'the ladjaeeiit-iiragj'` t is no tlstiiijig to attract the arm afdjiacent'to tli'e u radial arm, itbeing 36 from the magnet inl stead of 1'8"' and th'esa'nie applies totheother radial arms,- w'hicliI iare" beyoi'idy the; 18",` Since' eachof thea radial arms are a the nag-s sin:y 5, wier passai-f fof 16a motion; withthe eicepti'oiiof one arm, vvlri'crl'-r isfurthestA disposed: from: the magnets 13", there being iio'need for" lost motion int-his' instance, -the' ain nearest the: position will* be'attractedbyftlie magnetz opl-f posi-te thereto a-ndi tu'r'n will revolve'eabli of thel radial armsthrough1 ai Correspndingv distance of 1180.4 Ks soonas the ne'iitupper mostx arm r'e'ache's'fthe-v position 18 fionitthe" magnet opposite'fl-y disposedg t it,thef^iiiove"" ment willibe continued` and each arm will: be 'revolved through: a siecondlS", Ynii'ivernent being continued until"` each*radial"a'riii'y cori-Y tactsi-with its'corres'poniing magnetfa'nd tlifeE shieldllia's been raised-from perpendi' l' ular, operative position-,td alibriz'ont'al operative position.
