Application filed March 8,1926. Serial No. 93,006.
embodying my improvements; a cross section being shown on the line 1-1 of Fig. 3, with the lens and retaining ring in position.
Fig. 2 is a side elevation looking in the direction of arrow 2 Fig. 1, but showing a cross-section on the line 2-2 of said figure fvith the head band indicated only by dotted mes.
Fig. 3 is a front-face view looking in the direction of arrow 3 Fig. 1, but showing a cross-section on the line 33 of said figure.
Fig. 4 shows the two parts of the ventilating device in edge view, slightly separated as preliminary to being telescopingly engaged.
Figs. 5 and 6 indicate a modified construction of the two part ventilating device, Fig. 15? being a cross-section on the line 6-6 of The eye cup A may be of ordinary form adapted at its forward portion to receive a lens B, and having the outer portion 10 of its approximately cylindrical wall extended so as to provide a properly curved facecontacting edge 11. An inwardly extending flange 12 provides an annular offset against which the outer portion of the lens face is seated when in place, and a circular opening 13 in the extended portion of the cup wall provides for the reception of a ventilating closure communicating with the cupped space between the lens and the users eye.
The lens B is inserted loosely in the lensreceiving forward portion of the cup, against the seating flange 12; and I provide for very conveniently placing or removin it, and at the same time yieldingly yet relia b retaining it in contact with the seating flange or offset 12. This I accomplish by forming a circular groove 15 in the inner face of the cup wall and properly spaced from saidlens seat; and by employing as a retain ing means a compressible flexible ring 16 adapted to be inserted rearwardly into the cup and into engagement with said groove by ready distortion of its normal shape and resumption thereof after being thus forcibly engaged in the groove. This ring 16 is preferably made of soft rubber or like flexible materiahand of a normal diameter equal to or slightly greater than the diameter of the groove 15, so that it may be readily passed through the smaller portion of the cup and into snug engagement with the groove 15 thereof, and when so placed will exert a suflicient retaining pressure against the lens While at the same time affording a yielding resistance to such impact of foreign'material as would ordinarily be injurious.
For securing proper ventilation of the cupped space behind the lens of the applied goggle, I employ a ventilating closure for the cup-wall opening 13 which is made up of two separately formed cup-shaped parts, 20 and 25, which are telescopically engaged; one of these parts bein rigidly secured to the mm of said opening, y flaring the inserted cylindrical edge 20= as indicated, while the other is tightly engaged with it telescopically soas to arrange the closure or bafile plates 20", 25 in parallel relation with an intervening space 21 between them. Each of these opposed plates is apertured, as indicated, by turning inwardly a cut portion of the plate, so as to provide an aperture 20 or 25, and an adjacent partition or deflector 20 or 25 within the space 21; so that only an indirect passage-way is provided between the-outer and inner apertures 20, 25, throughsaid intervening space, and objectionable admission of light is effectively prevented.
The preferred construction specifically set forth may be modified within the scope of my invention; as indicated in Figs. 5 and 6 where the telescoping ventilated parts are shown differently but equivalently apertured, each part being formed with a series of inturned eyelet apertures, 20 or 25, communicating indirectly through the space between the connected parts.
What I claim is:
1. In a goggle eye-cup having a ventilating opening in the side wall thereof; a ventilating closure for said opening comprising an outer cup section clamped to the wal opening edge and a reversely arranged inner cup section telescopingly engaged in said outer section; the spaced apart end plates of said cup sections being formed with non-registering ventilating apertures and with baffies on the respective plates extendin to? ward the opposed plate to provide in irect communication only between said apertures.
2. In a goggle eye-cup having a ventilating opening in the side wall thereof; a ventilating closure for said opening secured to said wall and comprising separately formed inner and outer closure plates spacedly arranged in the opening; said closure plates being formed with non-registering Ventilator apertures and with baflles on the respective plates extending toward the opposed plate to provide indirect communication only between said apertures.
3. In a goggle eye-cup having a ventilator opening in the wall thereof; a ventilating closure for said opening comprising a cupshaped closure part rigidly securable in said wall. opening and having a portion of the projecting closure plate thereof inwardly turned to form a ventilating aperture therein and the projecting rim portion adjacent said aperture provided with a head-band-engaging slot communicating with said aperture.
4. In a goggle eye-cup having a ventilator opening in the wall thereof; a ventilating closure for said opening comprising an apertured cup-shaped closure part rigidly secured in said opening so as to project exteriorly of the cup wall and having its rim portion provided with a head-band-engaging slot.
In testimony whereof I aflix my signature.
HARRY F. SHINDEL.
