Specification of Letters Patent. Patented Dec, 27, 1921.

Application filed August 23, 1919. Serial No. 319,307.,

To all whom it may concern: I

Be it known that we, Fnnonnron i /Ellison and HARRY F. SI-IINDL'L, both citizens of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Tm provements in Goggles, of which the following is a specification.

This invention relates to eye protectors; and it consists in the improved construction hereinafter set forth in connection withthe accompanying drawing, and the novel ieatures or" which are fully described, and specifically defined in the claims.

Figure 1' is an inner face view of complete. eye protector embodying the several features oi the invention in preferred form; one of the pivoted eye shields beingrepre sented in outwardly-swung operative position, and the other one, together with the pivoted temple indicated, being shown in folded position.

Fig. 2 is a correspon the left hand clamping c ip and its attached head connection being disconnected and shown separately in Fig. 3. f

Fig. 1 is an outside-edge view of the split lens lamping framing, as it appears preliminary to inserting the lens; the latter being shown separately in Fig. 5 in connection with an edge-reinforcing ring. The eye shield is indicated in raised position.

Fig. 6 is a similar view to Fig. i, but showing the framing preliminarily closed upon the inserted lens, and so held by the fully swung eye shield.

Fig. 7 shows the separateiy formed framing end-pieces.

Fig. 8 is an enlarged View of a portion of the lens framing, in connection with, a showing of the clamping clip as about to be engaged with thetraming end pieces; Fig. 9 being a similar view showing the fully engaged clip, in vertical section.

Figs. 10 and 11 are vertical views of 1e clip and of the nose-bridge end portion r-' spectively.

Each lens framing, as shown, is formed or" folded sheet material, with a ions-edge engaging portion 10, and a circular eye cup or flange extension 11; and is provided with end- piece members 12, 12 adapted to be clamped together for securing the inserted members.

ng top-edge view lens 13. The eye shield 15, pivoted to the lens framing extension 11 at 16, 16, has its curved base portion 17 formed with a circular groovelS which is adapted to engage the top-edge portion of the framing exten sion 11 when the shield is swung outward to its operative position; the shield, when thus engaged, holding the abutting end piece members 12, 12 together so as to retain the previously inserted. lens and permit the easy applicationoi' the spring-clip 20 to said This clip is attached to the usual temple or head band connection 21 and is adapted to clampingly engage the end piece members 12, 12 in a manner similar to that shown in Vfillson Patent No. 1,323,431 of Dec. 2, 1919, but with improved efiect as hereinafter fully described. V

The end- piece members 12, 12, as shown in Fig 7, are separately formed, with flange portions 22 for rigidly securing them to the abutting ends of the split lens framing; and they consist of abuttingly arranged plates, the lower portions of which are formed with clip-fulcruming offsets 25 on their inner edges, and the upper portions with tit-engaging recesses 28 to provide frictional enagement with thefully engaged clip. The atter, as shown particularly in Figs. 8,19,

blank; its spaced-apart walls providinga flared opening 27 between them for the easy passage of the abutted end piece members 12, 12, and being connected by a bottom and 10, is formed from a tolded'sheet metal cross-bar 28 which is adapted to engage the f fulcruming offset 25 of said members. Ex

tending portions 80, 30 of the clip walls form a temple bar connecting jaw, and inwardly projected tits 31 of the clip walls are arranged to frictionally engage the recesses 26 of the end-piece members after the ful-y crumed clip has been forced into fully engagged position upon said members.

The circular extension 11 of the framing, which forms a shallow eye cup portionand serves, as already described, for connection of the pivoted eye shield, and for clampingly edge inwardly turned, to conform it approxiengaging the latter when in outswung' posi' base of the nose.

mately with the spreading sides and rounded The nose bridge connection of the framings consists of a shaped bridge bar, having T-shaped ends formed by separate plates 85; the raised intermediate portion of each of said plates being shaped to firmly seat the turned end of the bridge bar, which is rigidly secured thereto, and the ends of the plates being shaped to the curvature of the framing extension 11 and suitably fastened to the latter so as to provide any determined spread of' the lens framings.

In assembling the parts,or in removing and replacing the lens, the ivoted shield operates in connection with the detachable spring clip to greatly facilitate the clamping operation. The shield itself is adapted to hold the spli' framing together, upon the readily inserted lens; and it enables the spring clip, which completes the clamping, and firmly secures the temple or head securing means, to be easily applied orremoved; While the improved clip construction provides a convenient fulcrum upon which the device is swung with proper leverage for securing the final frictional engagement. The special shaping of the eye cup framing eX- tension to which the eye shield is pivoted, adapts the latter to serve as a preliminary lens-clamping means and at the same time provides a symmetrical nose-contact and for the improved nose-bridge attachment,

What we claim is 1. in an eye protector, a lens-clamping framing having opposed end-piece members and an eye-cup extension, a detachably enga' ed spring-clip band for the abntted members, anda pivoted eye shield adapted to hold said members together without interfering with the operation of said band.

2. In an eye protector, a lens-clamping framing having opposed end-piece members With clip-fnlcrurning offset, and a detachably engage spring-clip encircling said members and having an offset-engaging crossbar.

3. In an eye protector, a lens-clamping framing having opposed end-piece members with clip-fuleruming offset, and a detachably engaged spring-clip encircling said members and having an offset-engaging crossbar adj acent one end of its opening and a friction catch adj acent the other end thereof.

a. in an eye protector, a lens-clamping framing having opposed end-piece members with clip-fulcrumed offset, and a detachably engaged spring-clip encircling said members and having an offset-engaging crossbar adj acent one end of its opening, a friction catch adjacent the other end thereof, and a templeconnecting jaw.

In an eye protector, a lens-clamping framing iaving opposed end-piece members with clip-fulcrumed ofiset, and a detachably engaged spring-clip encircling said members and having an offset-engaging crossbar and a temple-connecting jawadjacent one end of its opening, and a friction catch adjacent the other end thereof.

6. In an eye protector, a lens-clamping framing having opposed end-piece members with clip-fulcruming offset, and a detachably engaged spring-clip encircling said members and having an offset engaging crossbar; the encircling portion of said clip having a flared opening for passage of the engaged end-piece members.

7. In an eye protector, a pair of lens framings each having an eye-cup extension, and a nose bridge bar having rigid T-shaped curved end portions extending circumferentially of the respective cups and rigidly secured to the latter.

In testimony whereof we aliin our signatures.

FREDERICK WILLSON. HARRY F. SHINDEL.
