UNHTE STATES earner FREDERICK WILLSON AND HARRY F. SHINDEL, OF READING, PENNSYLVANIA,

ASSIGNORS TO WILLSON GOGGLES INC., 015 READING, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA.

EYE-PROTECTOR ATTACHMENT FOB, SPECTACLES.

Application filed July 1, 1922. Serial No. 572,132.

To all whom it may concern:

Be it known that we, FREDERICK VVrLLsoN' and HARRY F. SHINDEL, both citizens of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Eye-Protector Attachments for Spectacles, of which the following is a specification.

This invention relates particularly to attachments for spectacles or eye-glasses which provide removably secured protection glasses in front of the correction glasses as shown in Patent No. 1,433,690, of Oct. 31, 1922; and it consists in the improvements fully set forth in connection with the accompanying drawings and clearly defined in the subjoined claims. Fig. 1 is a rear-view elevation of a pro tection-glass eye-cup embodying our present invention, shown attached to an eye-glass rim; Fig. 2 being a similar view showing a modified device applied to a templed spectacle rim, with a side shield extension of the cup indicated.

Fig. 3 is an enlarged cross-sectional view of the eye-cup attachment, on the line 33 of Fig. 1; and Fig. 1 is an enlarged end view of the same.

As shown in Figs. 1, 3, and -1- our complete device consists of a protection glass eye cup 10, formed of a splitring band of sheet material which provides an enclosing wall for the inserted rimmed eye glass 3 as in the patent previously referred to; said wall band however being adapted to clamp or release the protection glass 13, and being also provided with improved clips for engaging the inserted correction-glass rim, as hereinafter described. In Fig. 2, which shows the device in connection with a templed spectacle rim, a. separately formed hinged side shield is indicated adapting the same for use as complete goggles, and the preferred clamping means for the protectionglass is omitted and a modified arrangement of the rim-engaging clips indicated.

The adjacent free ends 11-11 of the split wall hand 10, are bent over outwardlv to form clamping eyes and in these eyes is engaged a tapered staple connection 12 adapted, by upward and downward movement respectively, to either clamp the rim-edge 1 1 of the band upon the protection glass 13 or to release the latter, as desired; the inward- 1 turned ends of this clamping device being adapted also, as shown, to form a head-band connection for conveniently securing the eye cup device and the engaged eye-glass frame to the head of the wearer.

The attaching devices for the correctionglass frame, upon the inner wall of the eye cup, comprise a fixed device 2021-22 adapted to provide pivotal engagement for the rim-and-nose piece junction 7 of the former as in our prior application referred to. In our present construction, the spring clip devices provided for engaging the outer portion of the correction glass rim, are formed by separate spring- metal strips 15, 15, secured to the inner wall of the eye cup band with their free rim- engaging ends 16, 16, arranged to swing in a plane substantially parallel to the plane of the clamped protection glass; so that said clip ends, after being first engaged with the outer portion of a correction glass rim, and then swung outward to permit engagement of the latter with the fixed device 2021-22, will lie in the plane of the secured correction glass rim. The extensions 17, 17 of the attached ends of these clip strips 15, 15, are shown as bent inwardly to form yielding abutments when the eye cup band 10 is clamped upon the pro- ,tection glass 13 by clamping device 12.

This z-idvantageous clamping arrangement for the protection glass may be omitted when the eye cup device is applied to aspectacle frame having a head connecting temple piece as indicated in Fig. 2; and the arrangement of the spring- clip strips 15, 15 may obviously be modified as indicated in said Fig. 2.

What we claim is:

An eye-protector attachment for spectacles consisting of a protection-glass eyecup having a rim-enclosing wall provided interiorly with a spring clip having its free end adapted to swing in a plane approximately parallel with the plane of the protection-glass and to engage an inserted spectacle rim.

In testimony whereof we affix our signatures.

FREDERICK WILLSON. HARRY F. SHINDEL.
