EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 709,892, dated September 30, 1902.

Application filed September 11, 1901. Serial No. 75,000. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. EssIoK, a citizen of the United States of America, and a resident of Reading, in the county ofBerks and State of Pennsylvania, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification.

My invention relates particularly to frameless eyeglasses; and my main object is to provide a simple construction formed of separate economically-formed parts rigidly built up so as to have the general appearance of a more expensive construction without resorting to objectionably soldering or brazing and providing a neat and substantial as well as relatively cheap construction.

The invention is fully described in connection with the accompanying drawings, and the novel features are specifically pointed out in the claims.

Figure 1 is a front elevation, partly in section, of an eyeglass-lens having my improvements applied thereto. Fig. 2 is a partly sectional View on the line 00 d3 of Fig. 1. Figs. 3, 4, and 5 show the clamping-post, which serves to rigidly connect the several parts strung upon it. Figs. 6 and 7 are separate face views of the distance-sleeve and nosebridge, respectively.

The lens strap or clip shown in the drawings is provided with a lens-clamping ear 3, arranged at about right angles to the rim portion 2, which latter contacts with the edge of the lens 1 and is extended around the latter, so as to assist in rigidly securing the strap to \the lens when the ear 3 is clamped to the latter, as usual. Instead of one clamping-ear, as shown, two may be employed, if desired. This strap may be readily stamped out of sheet metal and is preferably provided with a rectangular perforation 4,extendin g through the thickness of the rim portion 2 in the plane of the lens and adapted to permit the passage therethrough of the rectangular-bodied clamping-post 5 and to form a correspondingly countersunk seat for the head 6 of said post, which head is formed oblong, as shown, by opposite wings or extensions, leaving its width uniform with that of its rectangular body 5. Upon the outwardly-projecting body of this clamping-post after its insertion in the lens-clamp is mounted first a distance-sleeve 7. These sleeves are very cheaply made in an automatic drilling, turning, and cutting-0E machine from a rectangular rod of metal corresponding in size with the rectangular end or head 8 of the sleeve, a longitudinal hole 9 being drilled therein and the exterior turned to suitable form, with a base 10, adapted to seat against the outer face 11 of the lensstrap. The hole 9 in the distance-sleeve is preferably drilled to a diameter slightly less than the diagonal of the rectangular body 5 of the clamping-post, so that when forced home upon the latter against the lens-strap it will be tight on the post. readily enter the latter in the sleeve, its outer corners may be broken, as indicated at 12,

and the sleeve is so set on the post that the sides of the rectangular head 8 are parallel with the sides of the rectangular body of the post, as shown in Fig. 6.

The nose-bridge 13 and guard 15 each have connecting ends'corresponding in width with the head 8 of the distance-sleeve and an aperture 14 therein adapted to fit over the rectangular body 5 of the clamping-post, sothat, as shown, when strung upon the end of the latter and pushed home against the head 8 of the distance-sleeve their edges lie flush with the sides of said head, and being, like the latter, non rotatable on the rectangular clamping-post 5 are securely retained in this relation independently of the clamping operation which rigidly unites the several parts. This clamping together of the parts strung upon the clamping-post is preferably efiected by merely-riveting over .the projecting end of the post-body, which operation strongly draws the parts together and in connection with the non-rotatable mounting of the latter insures permanent rigidity in the structure notwithstanding the separate formation and loose assembling of the parts. In addition to the economy with which this rigidity of construction is secured as compared with the ordinary brazed or soldered structure, while maintaining substantially the general appearance of the latter, I am enabled to practically secure an improved effect because of the avoidance of soldered or brazed joints, which inevitably show, notwithstand- In order to' ing more or less costly finishing of the same and because the rigidity and stability of the connection is not dependent upon the nicety of machine operation, such as milling and screw-cutting, which are constantly liable to variations through wearing of the cutting tools employed.

What I claim is 1. The combination with the lens-clip having a rim portion and an angularbodied clamping-post projecting outwardly from said rim, of separate members strung upon said angular body so as to be held from rotation thereon and means for clamping said members on the post.

2. The combination with the lens-clip having a rim portion provided with an angular countersunk perforation in the plane of the lens, of an angular-bodied clamping-post having its head seated in said countersunk perforation so as to be held from rotation therein, a bow and guard perforated to fit the angular body of the bolt and strung thereon, and means for clamping said bow and guard on the post.

3. The combination with the lens-clip having a rim portion provided with an angular countersunk perforation in the plane of the lens, of an angular-bodied clamping-post having its head seated in said perforation so as to be held from rotation therein, a distancepiece nose'bridge and guard strung upon said angular body so as to be held from rotation thereon, and means for clamping said members on the post.

Signed at Reading, Pennsylvania, this 9th day of September, 1901.
