EYE WINDOW Filed Sept. 16. 1951 I nvenlor Patented May 3, 1932 UNITED STATES PArENT oFFicE JOHN L. L'UFKIN, OIE' NEW YORK, N. Y., ASSIGNOR TO THE ENGINEERING PRODUCTS CORPORATION, INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK EYE vVVIN'DOTT Original application filed November 13, 1925, Serial No. 68,781. Divided and this application filed September 16, 1931.
This invention is a division of application Serial No. 68,781, filed November 13, 1925, and relates to eye pieces or so-called eye windows adapted to be used for the protection of the eyes of workmen engaged in hazardous occupations. lVhile not limited thereto, the particular eye window disclosed is designed for use on protective hoods such as used by workmen operating paint sprayers.
The invention will be apparent from the following specication when read in connection with the accompanying drawings in which- Fig. 1 illustrates a protective hood having my improved eye windows secured thereto;
Fig. 2 is an enlarged elevation of the eye window as viewed from the inside of the hood;
Fig. 3 is a horizontal section on an enlarged scale on line 3 3 of Fig. 2.
Referring in detail to the drawings, 10` represents a hood made of any suitable eXible fabric such as canvas, rubberized cotton or other similar material. This hood is proa vided with a suitable respirator 12 and straps 14C adapted to gather the hood about the neck of the wearer. The hood illustrated is provided with improved means whereby the eye windows or eye pieces indicated generally by numeral 16 may be quickly and easily detached.
Protective hoods of the kind shown in Fig. 1 are practically a necessity for workmen engaged in applying paint by the use of pneumatic paint spraying machines in order to protect their eyes. An ordinary sheet of glass provides a certain amount of protection for the eyes but is open to the serious objection that when used in painting operations, the
- window soon becomes practically opaque due to the paint spray settling on the glass. This will be apparent when it is remembered that in applying this paint, the operators head may be said to be surrounded by sort of a fog or mist of paint. This is especially true where one or two operators are working in close proximity to one another.
To prevent the eye windows from .becoming opaque or being rendered practically nontransparent, I provide a screen consisting of Serial No. 563,086.
wire of very fine mesh such as indicated at 36 in Figs. 2 and 3. rPhe screen is in the form of a disc-like member to the peripheral edge of which is soldered, welded or otherwise secured a wire ring 38. This ring serves to reinforce the edge of the screen and also to space it away from the surface of the eye window 18 as clearly shown in Fig. 3.
`As shown in Fig. 3, the screen 36 is seated against an annular flange 42 formed in a supporting frame 52 which is substantially 'l-shaped in cross section and provided with a groove 54C which accommodates a snap kring 5,6 which overlaps the peripheral edge of the window 18. The frame 52 is formed with a sleeve-like portion 58 which is screw threaded for coaction with threads on the ring 60. The latter is formed with an annular bead 62 which when the ring 60 is screwed down on the sleeve portion 58 is adapted to force the fabric of the hood into a. circular groove 64 formed in the frame 52 so as to e'ect a practically dust and moisture tight seal between the hood and the frame.
An eye window equipped with the protective screen device such as above described can be used in applying paint for long periods of time without becoming opaque even though a great deal of paint settles on the surface of the screen wire. A practical test shows that when to all appearance the screen is coated with paint it is still possible for the workman to see through the window. The screen protected window, therefore, has to be cleaned much less frequently than the unprotected type of window. And because of the novel arrangement of the various parts, the glass and also the screen can be very quickly and easily detached from the frame 52 for the purpose of cleaning the same and the frame. itself can be very quickly and easily detached from the fabric of the hood when it is desired to wash the latter.
While I have described in detail the construction of arrangement of the particularv embodiment of the invention illustrated, it is to be understood that various changes may be made by those skilled in the art without departing from the invention as deined in the appended claims.
What I claim is 1. An article of manufacture comprising an annular eye Window supporting frame of substantially T-shape in cross section so as to provide radially and axially extending flanges, an eye Window, a atproteetive screen contacting With one of said radially extending ianges, said screen having a marginal spacer ring secured thereto and contacting-With the flat surface of saidv eye Window, said axially extending flange having a grooved seat therein and a split ring seated Within said groove and engaging said eye Window.
2. An article of'inanufacture comprising an annular eye Window supporting frame of substantially T-shapein cross section so as to provide radially and axially extending flanges, van 'eye Window, a lat protective screen contacting With one of said radially extending flanges, said screen having a Inarginal spacer ring secured thereto androntacting with the at surface of said eye Window, said axially extending flange having a grooved seat therein and a split ring seated Within said groove and engaging said eye Window, the outer surface of said axially extending lange being screw threaded and a clamping ring in screu7 threaded engagement With said axial flange.
In Witness whereof, I have hereunto signed my name.
