"ANTW-Lann SHIELD ronArrToMom-LE Leurs l i -Application ima engin-.st 2a, 1921. 'semi m 214,921
This inyention relatesto anti-glare shields for automobile lamps, and the general object of the invent-ion is to provide a shield that simple, very cheap to produce, and which may:
be readily 'applied to any automobile head; light lamp,
Our invention is illustrated in the accom` .panying drawing, wherein:-
Figure l is a side elevation of alamp bulb having ourshieldattached thereto;
Figure 2 is a front elevation of the bulb with tl'ieshield attached;
F ignre 3 is a perspe'ciziie view/tr of the shield; Figure 4 is a. plan view of the blank onr which the' shield' is made.'
Referring .to this drawing, it will be seen that our anti-glare shield is formed -of lone sheet 'of metal, as illustrated in Figure 4, Ithis blank being formed to provide a relatively jwide body portion-10, a narrow neck l1 at the fior-ward end of the hodyfportiori, and a circular diskglZ. The body portion 1.0. of the shield has its side edges inclined slightly tov'Ward the neck 11.` Rearward of the b'odylO `the shield is formed with a longitudinal prolonged portion 13*- andV two lateral lags 13.
The blank is formed so that the body por? tion l0 is longitudinally curved, the disk 12 being bent at the neck 11 s as to 'extend `down in front of the axial center of the bulb. The Alugs 13 are semiecircularly bent so as to-embrace' the neckof the lamp or the base thereof, the ends ofthe-lugs beingoiitwerd'ly turned, as at 14, affording means wherebyl the lugs 13 e base p ior l tion of the lamp liu-lb or socket for whereby the lugs may be opened out so as topermit the rea-dy remogsa'l of-the device, The disk 12 is preferably"concavozconvex, as shown, and 5U' Apreferably the portion 1'0 is formed r'ifitl-L 'f i longitudinally extending -rib- 15 which acte to strengthen the portion 10 and render it more rigid and' more roten-tive ofthe forni tow-hich it has been bent. r
The portion 10 t-alies'lcarej of `the top glare, while the centrally disposed ,disk-19, takes carel ofthe `central glare. The small extension 13'* which projects' rearward of lthe. lugs 13' is adapted to fit between the buil-h Landthe socket 60 i l so 'as to hold firmly i-n place.-
This device does not h'ca't the bulbli-ke-othe-r devices for the same purpo'seand' it permits the light to Ahe thrown the saine-distance ahead .It kills the glare of tl-ieggoncomingcar-and 1 spreads the light to a 45 angle on'each side of the roadsotha't the entire road even beV 0nd the fence postsis guten a clear, even'.lig t.
Acan he lblown in the'b'ulb if desired.
' XVe claim As an article-of manufacture, .amanti-glare dimmer-for headlights for-med :from a single 75 sheet of metal andi-providing,- relatively n wide, transversely .fiat lonfritudinaily curved body portion havinga'longitudinally'extendmg rib, e'coricavofconvex disk-lijke portion .at
the forward end .of the' 'body portion eonnect- 80 ed by a neck thereto and extending substantinlly at right angles-to the body-portion,the body portion having a rear extension, the re'ax end of 'which is ,adapted to .fit within the socket of "i1-'lmnp and said extensions ha ving'cnm-'ed 85 -conffrontin(r lugs adapted ,to 'embrace the' base chimp uib.
