I, SIGMUND LÖWENSOHN, of Fürth, in the Kingdom of Bavaria and German
Empire, Merchant, do hereby declare the nature of this invention to be as
follows:
This invention relates to protecting eye glasses, and has for its object in such
a device the circulation of air to prevent the over heating of the eyes, when
protected by the glasses, without permitting foreign bodies to enter through the
air orifices into the eye.
In the accompanying drawings:-
Figure 1 is a plan of the protecting glasses seen from above.
Figure 2 is a front view.
Figure 3 is a vertical section on the line -x.
Figure 4 is a view of a simpler form of construction.
Figure 5 is a vertical sectional view on the line y―y.
The frame of the glasses, conveniently made of sheets of aluminium celluloid
or other suitable material, is shaped at the back so as to correspond with the
outlines of the face, and if desired it is also provided with an elastic rim b.
Orifices are arranged along the whole frame, or parts of the same, particularly
on the lower and upper parts, which permit the circulation of air in the enclosed
space around the eye.
In the form of construction shown in Figures 1, 2 and 3, the orifices e are
formed by providing a divided frame the part which rests against the face
being oval and narrower than the part a which carries the glass e
Both parts
are bent over at the rim and extend over each other to such an extent that the
bent rims form an S shaped air passage.
The bent rims prevent foreign bodies, whether solid or fluid, entering the
interior of the protecting glasses, therefore the latter are especially suitable
for mines and chemical works.
Figures 4 and 5 show a simpler form of construction. In this case the orifices
are formed by perforating the frame at several parts f, the substance of the
frame overhanging the orifices in front and preventing small particles entering
the enclosed space.

in and by the following statement: -
This invention relates to protecting eye glasses and has for its object in such
a device the circulation of air to prevent the over heating of the eyes when
protected by the glasses without permitting foreign bodies to enter through the
air orifices into the eye.
In order that this invention may be the better understood I will now proceed
to describe the same in relation to the drawings accompanying the Provisional
Specification.
Figure 1 is a plan of the protecting glasses seen from above.
Figure 2 is a front view.
Figure 3 is a vertical section on the line -.
Figure 4 is a view of a simpler form of construction.
Figure 5 is a vertical sectional view on the line y-y.
The frame of the glasses, conveniently made of sheets of aluminium celluloid
or other suitable material, is shaped at the back so as to correspond with the
outlines of the face, and if desired it is also provided with an elastic rim b.
Orifices are arranged along the whole frame, or parts of the same, particularly
on the lower and upper parts, which permit the circulation of air in the enclosed
space around the eye.
In the form of construction shown in Figures 1, 2, and 3, the orifices e are
formed by providing a divided frame the part a' which rests against the face
being oval and narrower than the part which carries the glass c.
Both parts
are bent over at the rim and extend over each other to such an extent that the
bent rims form an S shaped air passage.
The bent rims prevent foreign bodies, whether solid or fluid, entering the
interior of the protecting glasses, therefore the latter are especially suitable
for mines and chemical works.
Figures 4 and 5 show a simpler form of construction. In this case the orifices
are formed by perforating the frame at several parts f, the substance of the
frame overhanging the orifices in front and preventing small particles entering
the enclosed space.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:-
1st. In protecting glasses for the eyes the arrangement in the frame of orifices c
covered in front and adapted to permit the circulation of air in order to prevent
the overheating of the eyes, substantially as described.
2nd. In protecting glasses for the eyes as claimed in Claim 1 the frame a made
in two parts and a¹, having a zig-zag air passage, substantially as described.
Brd. In protecting glasses for the eyes claimed in Claim 1 the frame a having
perforations and covers arranged towards the front to protect the orifices, sub-
stantially as described.
