INC., 01 READING, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA. V

GOGGLES.

Application filed February 16, 1920. Serial No. 359,006.

T 0 allwhom it may concern.

Be it known that I, HARRY F. SHINDEL, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Goggles, of which the following is a specification.

My invention relates to goggles and particularly to sheet material lens framings therefor; and it consists in the improved construction affecting the convenient and advantageous mounting of lens hereinafter described fully in connection with the accompanying drawing, the novel features being clearly defined in the claims.

Fig. 1 shows a longitudinal section of a goggle cup embodying my improvements.

Fig. 2 is a partial end elevation of the same, with a portion in section.

Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view on the line 4-4: of Fig. 2.

The goggle cup 5 as shown, corresponds in a general way with that of my Patent No. 1,296,707, of March eleventh, 1919. being formed from a folded sheet-material blank with outwardly turned clamping ends 66 which are engaged or disengaged by a clamping device 7 to fasten or release the lens 8, and being also provided with an edging 9 as in my Patent No. 1,306,357, of June nineteenth, 1919: my present improvements however relating to special features affecting the mounting of the lens and hereinafter fully described.

In eye protection glasses for metal workers or like purposes, it is well recognized that a lens reenforcing seat as provided for in Willson and Bourquin Patent No. 1,161,- 100, of November twenty-third, 1915, greatly reduces the likelihood of fracture and the danger from shattered glass. In my improved construction as shown, such a reenforcing seat 15 is provided as indicated, by the doubling up of the sheet material which forms the cup 5 so as to produce an annular flange extending inwardly sufliciently to provide contact with this inner face of the lens at a substantial distance from the periphery of the latter; a co-operating flange 16 being also provided, having an edge portion 17 arranged in a plane parallel with the seating flange 15 and arranged toonly slightly overhang the periphery of the lens for the purpose of retaining the latter in contact with the extended seating v To conveniently ment of a nose bridge for connection of a pair of these goggle cups as usual, I utilize this doubled-up seating flange formation as a means of rigidly securing a nose bridge member 20 to the cups 5 a thin end portion 21 of said separately formed member being inserted'in the fold of the sheet material and tightly clamped thereby in the final closing 21 is provided with lateral anchoring extensions 2222 which are tapered to avoid any offset in the flange, and the necessary bulge in the thickness of the flange is thrown in ward so as to maintain a level seating face for the lens. 3

The placing and removal of the lens is effected by temporary removal of the clamping device 7 from the clamping ends 6 of the folded cup. To facilitate these operations I have found it advantageous to provide for maintaining a connection of these clamping ends without interfering withthe necessary spreading of the lens engaging portion of the cup; and for such purpose I have formed at the upper portion of one of the clamping ends 6 a lateral lock extension 25, adapted to enter a corresponding aperture 26 in the opposing clamping end. This locking device has a retaining offset 27 which is passable through the aperture 26 by suitably tilting the clamping ends, but serves to normally prevent disconnection of said ends while permitting required spread for inserting or removing a lens. I

What I claim is:

1. A goggle eye-cup comprising a folded sheet material framing having a lens-engaging circumferential edge and a.cupforming portion with outwardly turned clamping ends, and a clamping sheath slidably engaging said clamping ends; the abutting turned-edge portions of the latter being proprovide for the attach-,

vided respectively with a locking extension and aperture for loosely engaging the same irrespective of the clamping sheath.

2. A pair of sheet-material lens-clamping framings, each having integrally formed opposedlens-e d 'e-engagingrflanges the ,rearward one ofvv hicli comprises an inward fold of the sheet material constituting an-- annular lens-reenforcing seat of doubled thickness, and a connecting nose bridge member having end portions arranged parallel with the respective lenses and rigidly clamped in the folds of the doubledup material.

In testimony wherec'if I agfiix signature.

HARRY F. SHIN DEL.
