ALFRED D. XVARREN, OF VORCESTER,MASSACHUSETTS.

SPECTACLE EYE-SHIELD.

SPEGIFIGATION forming' part of Letters Patent No. 466,896, dated January 12, 1892.

Application filed August 1. 1891. Serial No. 401,342. (No model.)

To all whom it may concern:

Be it known that I, ALFRED D. WARREN, a citizen of the United States, residing at Vorcester, in the county of W'orcester and State of Massachusetts, have invented a new and useful Improvement in Spectacle Eye- Shields, of which the following is a specification.

The aim of this invention is to produce a new and improved eye shield or protector that may be used in driving by workmen in shops, &c. l

To this end the invention consists of the device described and clairned in this specification and illustrated in the accompanying drawings, in which-- Figure 1 is a front elevation of my shield open and ready for use. Fig. 2 is a rear elevation. Fig. 3 is a plan. Fig. 4 is a view of one of the blanks of which the device is made, and Fig. 5 a plan with the device closed.

My device consists, primarily, of two sections of peculiar construction and nearly similar in form, which are transversely hinged together.

In detail, A and B represent the rims, of thin flexible metal, which are Originally stamped out, as shown in Fig. 4. The two blanks for each eye-piece or section are exactly the same, eXcept that the piece B may have three hingejoints and the piece A may have two. Each blank consists of the rim, projecting from which are the two series of tongues a and b and the projections c, which are formed into the hinge-joint, as described further on. The blank also has the projection d, punched wherein is a small hole, in which may be secured means, as wires or an elastic, for holdinf;` the shield on the face. On the rim is placed a piece of mica, gelatine, or other trans` parent material, preferably but not necessarily of a fiexible texture. This piece of mica M is cut out the same shape as the rim and is laid on the same, and the tongues or fingers a are back or over to secure the same in place, as shown particularly on the righthand section in Fig. 8. Now a piece of felt or other suitable material is bent` to fit the rim, as shown, and these pieces of felt are cut 01' stamped out in suitable form in large quantities. The pieces of felt are formed with suitable holes, as g' 92, to afford ventilation and with suitable notches f. The felt is placed around the rim, and the tongues b. are bent over to fit the notches f and hold the felt in place on the rim. Further, it will be seen that the notches f form additional ventilatingholes, and as the tongues b fit in the notches no part of the metallic rim Will come into contact with the face of the wearer. The pieces c of the blanks are bent back and preferably soldered, so as to form hinge-joints, and a suitable pin p is setin these joints, preferably by heading the same over, so as to form a hinge connection between the two sections. Fastened to one of the Sections are one or more projecting pieces g, which bear against the lother section when the two are opened, so

that the Sections can only be opened to the position shown, but so that the two sections may be folded back on each other, as shown in Fig. 5, for convenience in carrying. Further, it will be seen that when the Sections are folded together the lfelt will protect the mica from being scratched.

The manner in which my device is used is apparent. The sections are opened out as shown in Fig. 3, and as the mica and the rims are fiexible the device can be closed to snugly fit the face. It' the mica should be broken, there would be no fiying pieces to strike the eye; but as the mica is not brittle this is not liable to happen.

I con template in someinstances usinglenses, so as to form a pair of glasses. By the use of colored mica the device is of great utility on the water, the., where it is desired to protect the eyes from the bright light and the wind. Further, as the deviceis entirelyput together without the use of glue the same cannot come to pieces if eXposed to moisture or if dampened from pel'spiration from the face of the wearer.

I contemplate in some instances oniitting the hinge-joint and making the device in one section; but for most purposes the hinge is an important point.

Modification's of the device heren described may be made by a skilled mechanic without departing from the scope of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An eye-Shield comprising two trans- IOO parent sections, each constructed of flexible materials, transversely hinged together, substantially as described.

2. An eye-Shield consisting of two transparent sections transversely hinged together, each section being made of a fiexible transparent material, and a Vflexlole binding for each section, substantially as (lescribed.

3. An eye-Shield consisting of two transparent Sections transversely hinged together, each sect-ion made of mica and havinga binding of light fiexible metal, and a strip of felt or other suitable material held by each ofsaid bindings, substantially as described.

4. An eye-Shield consisting of the rim having two sets of fingers, as a and b, a transparent material held in place vby'the fingers a, and a strip of felt held in place by the fingers b, substantially as described.

5. An eye-Shield consisting of 'the rim having two sets of fingers, as a and b, a trans- Vparent material held in place by the fingers a, Iand a strip of felt or suitable material held in place by the fingers b, the felt being notched,

;asaat f, to receive the fin-gersb, substantially as ,described having the extending projections g, so arranged that the Sections can be opened so as to be only in substantially the same line and so that the same can then be benti to fit the face, substantially as described.

8. The blank for eye-shields, comprising the rim having the two sets of laterally-projecting fingers, as a and b, and the extending pieces c, which may be ben-t to form, h-ingejoints, substantially as descri-bed.

In testimony Whereof I have heren'ntomset my hand in the presence of two subscrib-i-n-g witnesses.

ALFRED D. WARREN.
