Patented ov.4 28, `1944 George H. Schauweker. Southbridge, Mass., assignor to American Optical CompanyfSouthbridge,Mass., a voluntary association of Mas- -sachusetts Application December 23, 1942, Serial No.' 469,917

Claims;v (Cl. 2 9) 'I'his invention'relates to improvements in face shield means and has particular reference to novel means for supporting said shield means in position of use.

One of the principal objects of the invention is to provide novel nose and brow shield means adapted to be attached` to and supported in position of use by spectacle type goggles.

Another object of the invention is to provide` a shield of this nature having portions adapted to lie between the face of the wearer and the por tions of the goggle that tend to contact the face. Another object of the invention is to provide novel means whereby a shield of this nature may be quickly and'easily attached to a goggle frame.

Another object of the invention ls to provide a nose and brow shield that is simple and economical to manufacture.

Other objects and advantages of the invention v will become apparent from the followingdescrip.

tion taken in connection with the accompanying drawing, and it will be apparent that many changes may be made in thedetails of construction Vand arrangement of parts shown and described Without departing from the spirit of the invention as expressed in the accompanying claims. I therefore do not wish to be limited to the exact details as the preferred form only has been shown by way of illustration.

Referring to the drawing: f

Fig. 1 shows a front view ofthe nose and brow protector attached` to a spectacle goggle.

Fig. `2shows the nose and brow protector in its blanked out form and `before folding and stitching. I

Fig; 3 is a sectional view of the nose and brow protector as taken on line 3-3 of Fig. 1, Iand shown in position with a profile view of a face.

In the past, Vseveral different types of nose shields have been made for the particular purpose of protecting the nose from the rays of the sun. These shields were generally made ofa rigid plastic material and were plvotally'connected to the spectacle or sunglass by means of metal hooks which were adapted to be hooked over the bridge of the spectacle. Other types were provided with integral connection means which were formed on the outer edges of the shield and were adapted to snap over the bridge and adjacent rim portion of a spectacle.

v While devices ofV this nature served the purpose lfor which they were intended, it will be seen that they would not bei practical if used with a goggle such as worn by a furnace worker or the'like, as they would not provide heat insulation between the goggle and the face.

Other devices have been made to insulate that portion of the nose that is contacted by the bridge Vmember of a goggle. These devices are in the form of leather Vstraps which are adapted to be wound about-the bridge of a goggle.v It may be seen that with constructions of thisnature that avery small portion of the nose would be protected.

It is'therefore the prime object ol?4 this invention to provide simple and eicient means for protecting the predominant parts of the nose and brow from' reflected heat and also to insulate the face from contact with the bridge and adjacent portions of a metal goggle, spectacle or other type of ophthalmic mounting which might become heated during use.

Referring more particularly to the drawing wherein like characters of reference designate the parts through the several viewsi, the device embodying the invention as shown in Figs. l to 3 inclusive comprises broadly shield means which is preferably formed of sheet-like ilexible material such as leather, asbestos or other heat retarding material. The shield is preferably'blanked or otherwise cut to the contour shape desired from a larger sheet of material and, as shown in Fig. 2, comprises a nose shield portion 5 dimensioned to iit over and cover the major portion of the nose of the average individual. The nose shield portion 5 adjacent the top thereof is pro-- flared portions 9, which during use, is adapted to form a brow shield for the wearer. `The portion I0, as illustrated in Figs. 1 and 3, isprovided with an intermediate fold I I which causes the remainlng parts of the portion I0 to overlie each other with the tongue 8 overlying the nose shield 5. The folded portion III is provided with suitable transverse stitchings I2 which retain the parts in folded position. When in position of use, the nose shield portion 511s locatedl beneath the bridge I3 f -.of the spectacle type goggle and the brace bar I4 whereby the `shield means is retained in position of use and is readily detachable for replacement by another similar'shield when the` immediate shield hasperformed the extent of its usefulness.

The particular type of goggle with which this type shield is used has a pair of lens rims I5 con-v nected 4bythe brace bar Il and bridge member I3. Suitable lenses I6 are retained in the lens rims by separable endpieces I1 formed on the lens rims I5 in the conventional manner. 'I'he endpiece' members I .'I are secured together by a screw or the like 'I8 and also carry a pivot screw I9 to which the conventional temples attached.

Itis particularly pointed out that the shield member thus formed, particularly the part thereof lying beneath the bridge I3 and brace bar I4 not only provides means for protecting the wearer against heat radiation but also forms cushion means for increased comfort. The ared portions `9 are adapted to fltabout the bridge of the nose and extend downwardly over the sides of the nose to provide heat insulating means between the nose and the adjacent portions of the bridge and rims of the goggle and also to function as cushioning means which adds to the comfort of the wearer.

The nose shield portion is sov dimensioned as to overlie the maior part of the nose and has its side edges 2| tapered so that when the shield is tted about the nose the said edges 2| will lle in adjacent relation to the cheeks at the sides of the nose thereby affording full protection for the nose. .This portion of the shield also provides insulation means between the goggle and the face and is of extreme importance when the supporting parts of the goggle are formed of metal or other heat conducting material. The end of the tongue 8 has side portions 22 converging towards each other to. provide ease of insertion of the tongue in the respective loops 'I.

When in position of use and by reason of the fact that the bridge I3 and brace bar I4 are vspaced relative to each other with the shield means having portions tting about the opposed sides of said bridge and brace bar, the said shield means is normally held in substantial position of use with respect to the spectacle or goggle, that l is, there will be little tendency of the shield moving from its desired vertical position with respect to the -plane of the lenses. With the construction set forth herein there will be no tendency for the shield to rotate about the bridge or bar as a center even though the upper brow portion I0 and noseshl'eld portion 5 may be. lifted clear of the -face, as desired, during use.

It is pointed out that although the spectacle or V'fgoggle described herein is of the type which has "j both a bridge and brace bar, it is obvious that l' the shield means could be used with a spectacle `having only the brace bar joining the lens rims bridge member joining the lens orwith only a rims.

lSetting up the limits of the width with respect to the lenses, the brow portion I 0, as shown in Fig. l, when in position of use, extends in a sideways direction at least an amount suillcient to position the `ends thereof substantially midway of the lenses and aiords full protection for the face throughout the length of the brace` bar and the adjacent portions of the rims which might contact the face. The shielding means, in this particular instance which aiords such protection, is best Ashown by the dash lines 23 in Fig. l which are illustrated as underlining the rims.

With the arrangement set vforth above the bridge, brace bar and adjacent portions of the rims are completely insulated from the face by the' underlying portions of the shield means with the said shield means simultaneously functioning toprotect the wearer from radiated heat.
