EYEGLASSES.

SPECIFICATION formingpart of I IetterstPatent No. 701,819, dated June 3, 1902.

7 Application filed February 3. 1902.: Serial No. 92,488. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK A. STEVENS, a citizen of the United States, residing at Providence, in the'c'ounty ofProvidence and State of Rhode Island, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification;

My invention relates particularly to the binding means for securing'the post, noseguard, and spring, also to the peculiar con struction of the stud-terminal. V

The common form of eyeglass comprisesfa post terminating'in" a rectangular socket for the reception of asprin g and nosegu ard,which are retained in the socket by means of a bind-"- the contacting screw-head, and the parts are.

thereby loosened. The purpose of my inventionis to obviate this and other current defects by avnovel andinexpensive structure; and it consists in the novel construction and combination of parts 7, top and edge washer.

hereinafter described, and illustrated in the accompanying drawings, wherein- Figure lis a front View of a pair of eyeglasses embodying my invention; Fig. 2, a section on line a: or of Fig. 1; Fig. 3, a plan .view of the box-blank previous. to folding; Fig. 4:, a longitudinal central section of the same after folding; Fig. 5, an elevation of the bottom of the completed box; and Figs. 6 and views, respectively, of the Like marks of reference indicate similar parts throughout the views. I

Referring to the drawings by letters, a designates the lens-post,,engaged by clamps b with the lens 0. The post has a central cylindrical projection e'upon its-free end and is longitudinally bored to receive the screw d, which traverses the box A, the nose bow or spring f,'the guard g, and the washer h.

In detail the box A is formed, as illustrated in Fig. 3,'from an oblong blank having across its lower face transverse channels 7c, intermediate of which are similar channels Z, augmented midway their length by rectangular slots or depressions The channels aforesaid facilitate' the subsequent folding of the blank. The opposite ends 0f the blank are centrally provided with, semicircular openings j. By means of a plunger or suitable tool the blank is folded into the form of a' box, as shown in Figs. 4 and 5, having a circular openingj for engagement with the projection e of the post a, to which the bottom of the box A is soldered. The top of the box is pierced to allow admission of the head m of screw d. The latter is seated upon the washer h.' This washer is rectangular in outline,with integral ears or lugs n upon opposite sides adapted to register in theIvert-ic'al slots 'i of the box A. The edges of the washer h are in frictional Contact with the walls of the box, and hence will not turn in response to any movement of the guardor spring. While the washer is permanently retained in engagement with the box by means of its ears engaged in the slots 'i, the friction is not sufficiently pronounced to prevent longitudinal compensative adjustment to accommodate admissioninto the boxA of guards or springs of Varying thickness.

1 It isevident that the integral inclosed box em ployedhercin greatly strengthens the entire structure,while the novel construction of the same is inexpensive.

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

1. In eyeglasses, the combination with a post of a closed box composed of a single piece affixed thereto, slots at the opposite sides of said box, a spring and a guard within the box, a washer intermediate the top wall of the box and the spring and guard, said washer havand the spring and guard longitudinally movroe able in said slots, and a screw-threaded member whose head is seated upon the washer traversing the washer, spring and guard.

3. In eyeglasses, the combination with a post of aclosed box composed of a single piece aflixed thereto, slots at the opposite sides of said box, a spring and guard within the box, a washer intermediate the top wall of the box and the spring and guard, said washer havin glateral ears longitudinally movable in said slots and a binding-screw whose head is seated upon the washer traversing the washer, spring and guard.

4. Asa new article of manufacture, a blank for an eyeglass-stud consisting of an oblong metallic strip, four transverse channels upon the inner face of the same, two of which channels lie within the other two channels and upon either side of the center of the strip, and slots adjacent the two inner channels to receive the edges of an inclosed washer after the strip is folded.

5. As a new article of manufacture, a blank for an eyeglass-stud consisting of an oblong metallic strip, four transverse channels upon the inner face of the same, two of which channels lie within the other two channels and upon either side of the center of the strip, and rectangular slots adjacent the two inner channels to receive the edges of an inclosed washer after the strip is folded.

6. As a new article of manufacture, a blank for an eyeglass-stud consisting of an oblong metallic strip, transverse channels upon the inner face of the same, two of which channels lie nearer the center of the strip than the other channels, slots adjacent the two inner channels to register with the lugs of an inclosed washer, and openings in one end of the strip adapted to register when the strip is folded.

In testimony whereof I have affixed my signature in presence of two witnesses.

FREDERICK A. STEVENS.
