JOSEPH F. LAMB, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO LANDERS, FRARY & CLARK, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

EYE-SHIELD AND SECURING MEANS THEREFOR.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed March 20.11918. Serial No. 223,677.

To all whom it may concern:

Be it known that I, JOSEPH'F. LAMB, a citizen of the United States, and a resident of New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Eye- Shields and Securing Means Therefor, of which the following is a specification.

.This invention relates to improvements in eye shields, or similar devices, and means for securing them. in place.

In the drawings Figure 1 is a front view of a section of. fabric in which an eye shield is secured.

Fig. 2 is a sectional view on the line of 2-2 of Fig. l but on enlarged scale.

Referring to the drawings-A denotes a fabric or other material or structure in which the shield may be secured. 1 denotes generally the shield frame of annular form and reduced in diameter at one end 5, with its edge flared out as at 6, to provide an exterior annular channel. The fabric has an aperture smaller than the reduced end of the frame, its edge being slit to receive the frame and provide enough material to fold into the channel. The fabric at the edge of the aperture may be reinforced if desired as indicated at b. A securing spring 10, which may be snapped into the channel, has a bearing over a considerable area of the fabric, securely positioning the frame in place. For the purpose of easy removal of the spring when necessary, the wire from which it is made may be relatively soft, so that a metal point can be caught into the spring and the spring distorted permanently making its removal easy.

The reduction in diameter of the frame provides a shoulder 15, which as seen is preferably slightly inclined outwardly, and

against this shoulder is located a gasket 16; the eye shield 17, which may be of celluloid or some similar transparent material, lies against this gasket. The wall of the frame 1 is threaded, a securing ring "20, has threaded engagement therewith and is pro vided with an inturned flange 21', which has a slight annular bead or projection 22, to engage the edge of the shield 17. As the securing ring 20, is screwed down into place it engages th'outer edge ofthe shield 17,

over the opening and provides a secure grip for the edge of the eye piece, the effect of means.

back of the raised edge of the shoulder 15.

This results in stretching the eye piece tautly.

I claim as my invention 1. In a device of the character described an annular frameprovided with a shoulder, a gasket set against said shoulder, a shield member resting against said gasket, a securing ring engaged with said frame and provided with an inturned flange, and a projection on said flange for engaging said shield member. a Y e 2. In a device of the character described an annular frame provided with anoutwardly inclined shoulder, a gasket positioned against said shoulder, a shield memher with its edge resting on said gasket, and a securing ring engaged with said frame and adapted to bind said shield member against said shoulder.

3. In a device of the character described, an annular frame provided with an outwardly inclined shoulder, a shield member fitting within said frame and with its edge overlying said shoulder, a securing ring engaged with said frame and provided with an inturned flange opposite said shoulder, and projections on said flange engaging the edge of said shield member to bind it against said shoulder. v

4. In a device of the character described an annular frame having at one end a portion of reduced diameter the end of which is outwardly flared to provide an exterior annular channel, a fabric apertured to receive said reduced portion with the edge of the fabric at the aperture folded into the bottom of said annular channel, a spring member fitted into said annular channel and lying against said fabric to secure it to said frame, an annular shoulder formed in said frame by said reduced portion, a shield member fitted within said frame and with its edge overlying said shoulder, and a securing ring engaged with said frame and tomof said channel, and a ring-shape coil 10 having an inturned flange between which spring normally of smaller diameter than and the said shoulder the edge of said shield the bottom of said channel but t, adapted to member is positioned and clamped. be sprung into said channel to securely bind 5. In a device of the character described the fabric in place, said spring being made an annular frame provided at one portion of relatively soft wire to permit of easily. 15 withan exterior circumferential channel, a stretching it to facilitate its removal from fabric apertured to receive said portion with the channel. the edge of the fabric folded into the bot- JOSEPH F.
