EYEGLASSES.

APPLICATION FILED MAR. 4,. 1907.

I UNITED STATES GEORGE H. CHAPEL, OFHOWEL'L, MICHIGAN.

EYEGLASSES.

To all 'whom it may concern:

Be it known that I, GEORGE H. CHAPEL, a citizen of the United States, residing at Howell, in the county of Livingston and State of Michigan, have invented. j certain new and useful Improvements in Eyeglasses, i

of which the following'is a specification.

This invention relates in general to nose glasses, and

more particularly to the construction and arrangement of the various parts or devices thereof-cooperating collectivelyfor retaining the same to place upon the nose of the wearer and individually for supporting the i lenses in proper position with respect to the eyes.

The object of the invention is to provide a connection between the lens, brackets, and nose-bridge piv- 3 oted vto the lenses by one and the same means. 7 With these and various other objects, advantages and improved results in view the invention consists in the-novel construction and arrangement of parts wherein a rigid connection is made between the lens as regards vertical movement of the latter and with respect to any spring action on the part of the bridge or -its 'ends and in the employment of the same element to make said connections, so as to permit a pivot movement of the lens on the bridge in the plane of vision and to fix the guards to the lens.

In the accompanying drawings, forming part of this application, Figure 1 is a perspective view. Fig. 2 is a top view showing. in dotted lines the movement of the lens. Fig. 3 is a detail perspective'view of the nose-bridge. Fig. 4 is a detail perspective view of one of the guards or plaquettes. Fig. 5, is a detail perspective view of nuc ei the pivot-springs. Fig. 6 is a similarview of one of the studs. Fig. 7 is a similar view of one of the lens-brac ketsi Fig. 8 is a perspective view of amodification.

The same numeral references denote the same parts throughout the several views of-the drawings.

In the application of my device to an ordinary lens 1 the bracket 2 has the usual lens-edge bearing'3 ears 4 formed on the said bearings, with a slot 5 between them at right angles to the opening 6 in the lensbracket. The ears have central apertures 7, the lower one of which is screw-threaded. This arrangement of the ears obviates making the usual neck, lug, or projection from the bracket for connecting other parts of the device, and it affords a closer union of the parts of my invention with the lens.

The nose-guards 8 have preferably a curled top wing 9 with corrugated surface forming an aperture 10, a bottom wing 11, and a stem 12 all struck up from a flat piece, end 13 brought to right angles to the said wings by a. half twist of stem 12. The end 13 is part circular to conform-with ears 4 and has an aperture 14 and a straight edge 15 to bear against the base or end of the Specification of Beissued Letters Patent.

Original llo- 791,320. dated May 30. 1905. Serial No- 234,369.

Reissued Oct.- 29, 1907. Application for reissue filed March 4 1907. Serial No: 360,537.

I The nose-bridge 1G is not of spring metal, and it is l therefore not resilient, but is capable of being bent, i .if necessary, to suit various forms or shapes of the nose, i though ordinarily such bending will not be found necessary, inasmuch as the bridgeis only intended as a. 5 connectionbetwecn the lenses and not to rest on or i otherwise engage the nose. The bridge 16 has circui lar-shaped flat ends 17, which are turned outwardly l and forwardly from the bridge to leave a neck 17. The ends 17 have an aperture 18 and edge stop-lugs 19, which engage the base edge of the slot 5 to limit the movement of the lenses,.which with the guards are 5 controlled by a bowed or U-shaped spring 20, having coils and hook ends 22, and the bridge and guards are connected together and to the lenses by a screw-stud 23, having a journal-bearing 24 for the bridge ends 17.

in assembling the parts both lens connections being the same only one will be referred to. The bracket 2 having been clamped to a lens, the flat end oi the guard and of thenose-lrridge is placed in the'slot 5 with the bottom of the U-shaped spring resting in the neck 'of the bridge and the ends of the spring hooked over the front edge of the lens-bearing 3. Then the stud is inserted through the spring-coils and through the top: ear, bridge-end, and guard end into the screw aperture of the bottom ear. In this way the nose guards are pivoted to the'onds of the nose-bridge, and the clamps whi'cli'hold the lenses are also pivoted to the ends of the nose-bridge.

Referring to the modification shown in Fig. 8, the nose-guard 25 is made in the same piece with the bottom ear 26 of the lens-bracket 27. Otherwise this construction is the same as the preferred form.

It is well known that next to preparing lenses for correct vision it is of greatest importance to keep the lens against vertical movement, so that the vision may be through the center of the lens, for the least vertical variation will deflect the vision and impair the sight. Hence the importance of fixing the lenses permanently against vertical movement in placingand'removing the glasses. This is fully accomplished by the inflexible bridge having such connection with the lens and guards as to permit opening and closing of the latter in the plane of vision without the least vertical moverhent of the lenses or any of the parts oi the device.

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

1. The combination with the bridge, the lens-clamps and the hinges having pivots for hinging the lens-clamps .to theends' of the bridge of nose-guards held by the 'pivots' or said hinges 2. The combination with the bridge and a lens-clamp hinged to the end of said bridge of amuse-guard held by the pivot of said hinge.

3. The combination, with the bridge, or the lens-clamps l and the nose-guards pivoted to said bridge and having common pivotal centers.

4'. The combination with the rigid bridge and a lens:-

clamp hinged to the end of said bridge by a vertical pivot, of a nose-guard held by said vertical pivot and projecting back of said hinge and a spring engaging said noseguard; substantially as and for the purposes set forth.

5. In eyeglasses, the combination with the bridge, the lens-clamps and the.nose'-guards, of pivots connected to the lens clamps and to which pivots the bridge and nose guard are connected.
