Ya citizen ofnthe lliii'ted States, residingr at ic i Paterson. in the county of Passaic and State of New Jersey. have invented certain new and useful improvements in Vision Shields, of which the following is a specification.

The object of this invention is to destroy the -glare of the light of an approaching ve hicle in riding at night while preserving the visibility, it being within the object of the invention also that the dri-ver be not re quired t0 change his point of View. This object I accomplish by providing a shield composed of a series of translucent areas andVA a series of clear-vision areas Aarranged iii alternation with the translucent areas and respectively iinniediatel)1 adjoining and l e ing also appreciably narrower than thje translucent areas as viewed b v the user when said series' intervene-S between hii-ii and the objective and stan-ds substantially perpendicular to his line of vision. B v this forni of shield the two kinds of areas have a dis.- tinctv `L'ooperation with each other, Ithat is. their efi'ect on the drivers eyes is-finone or less a blended one. to the 'en d that wheieas the visibility is retained the glare is dcstroyed. and this without the driver shifting his point,- of vision. In the preferred forni each translucent area consists of a translucent body, as a vane, having surfaces in- 'fclined forward and downwardifrom the ob- Y Srvei"s side ofthe shield so that. he will y have the required better view of the'road forward^ of andi-niort: or less nearer lusowir vehicle than where the approaching light is. B v the use of in v invention the elein'ent of stantially the nature of that specified above safetv on roads at night is greatly increased.

principally vbecause the 'lights on vehicles do which may lie-readily attached `and adjusted to siii-t the requirements of the driver or -user and which shall be inexpensive to manufacture and strong-and durable.

-In the ac'coinlmnyingdrawing,

Figure 1 is a rear vieu of the shield shown mounted .on the wind-shield of an automobile; ai-id Figure 2 is a vertical sectional View of what is shown in Figure 1, bein-g' taken on line 2 2 in that figure.

a designates the aforesaid series of spaced plates. sheets or varies arranged in approxin'i-ately parallel planes each oblique to the series and each vane beinir t-raiisluc'ei'it., that is, capable of transmitting light rays without permitting obj-erts to be distinctly see-.fi theret'liroiigli. The material of the Yanes may beground or frosted, or suitably colored (as green-),- glas's or, preferably, celluloid or equivalent infrangible substance.

F or thesupport 'of these varies I- preferably provide the following structure:

There is :i rib b, which in crosssection' is Trsliaped tov give. it strength with lightness and which extends longitudinally of the series, or transversely of its component vanes, Y and is preferably arranged a )out midway between the ends of the vaiies. which are all of the ysame length, and back of them the rear of the device being"r to the. right as it is seen in Figui-e 2. a recess e at the fro-nt tliereofithat; is. in the vertical wel) of the T) which receives the series-of `Yanes. At the top it has an. extension or head L preferably 'formed flat, and near the bottoni and on theba-rk it has knob e'. I v

Two .U-shaped members f, preferably formed of sheet metal and secured at their This rib is formed with bentfoil ends g to 'the opposite sides of the l l ribrb at points above and below the recess c, are provided,- tliey bein;r reve-rse counte' parts of each other and serving as a niarg'iv l At suitably spaced; and' oblique points these i'iieiiibers have 'urnal frame for the varies.

their ui'iriglitportionsf' ielieiids h which f-orin at the inside grooves in which the endsv of the vvii-nes are Vreceived and suitably se# cured.

The wind-shield of .an automobile is indi cated at i, and this may serve a suitable means to which to attach my device. Thus I provide a clamp jliaring a suitable clamping'gdeviee sucli asma set-jserew 1(1)1 which has` pivot from the a fork-'shaped head .l receiving the hea-d l of "rib b. the two heads being penetrated by a screw-bolt m so that-a )ivotall adjustable connection is formed. `he dejv'ice-is shown.- secured by the clamp tothe `top of the windshield.l

In the operative position of my vision shield it is adjusted to stand lmore or less in the position shown by full lines in the drawing. In. this position, since the vanes a are translucentendhave some transparency the driver is not blinded by the light of a vehicle ahead of him and yet he has a fair :Pision ahead, but more or less near andahead or the vvehicle he has a erfectly unobstructed vision (downwardly Eetween the vii-nes) sothfit he can see and thus vavoid irre -laritics in the roadand other yobjects which he is only expected to see at short range. Even if the shield were swung forward -on its position shown in .Figure El, so that there would be clear visibility between the v'anes in the direction off an approaching light, I find in practice, since in the example illustrated the v'anes and spaces' are all horizontal, that the vision is not embarraed by the glare vof the approaching light, especially as the up and down motion of the vehicle incident to its travel over the road produces a shifting of the shield find the `driver-s eyes relatively to each otherA so that the glare is Aconstantly interrupted by the translucent venes. In short, the ,rays of light wing through the translucent area 'and c ear Vision area are in e'ect. blended, so that the visibility is retained but the glare is destroyed, 4find this, moreienwvithont the driver changing his point of view. In the daytime, or otherwise when the device is not in use, it may be swung u to the position shown by dotted lines in i-gum Q n i ving thus fully described .my invent-ion,

the translucent areas' and respectively immediately adjoining and 'appecinbly nnr- 59 row-er than the translucent areasns viewed by the user when said 'se-ries intervenes between him and the objective and stands Subr s tantially perpendicular to his line of vision.
