SPECTACLES.

SPECIFICATION forming part of Letters Patent o. 625,083, dated May 16, 1899.

Application filed January 23, 1899. Serial No. 703,105. (No model.)

T0 all whom it may concern.-

Be it known that I, WILLIAM E. BELT, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Im-` provements in Spectacles, of which the following is a specification.

My invention has for its object an improved frame for securing the lens in spectacles and providing a temple-joint for same. It has heretofore been customary to construct the joint-pieces integral with the bows and connect them with screws, rivets, or the like.

The primary object of my invention is to provide a frame which shall consist of as few parts as possible and be so assembled as to do away entirely with screws, rivets, soldering, &;c., and yet have a frame which shall be eX- ceedingly simple in construction, cheap and easy to manufacture, edective, and practically impossible to get out of order. To accomplish this end, I employ a single strip of wire to form the rim, and the bow is bent to form its own fastening at the temple-joint, and other novel features which will be hereinafter more fully explained.

In the drawingsFigure l represen ts a spectacle-frame,showing my improved form of rim and temple-joint. Fig. 2 represents an edge View showing one of the bows open and the other closed. Fig. 3 is an enlarged detail of the temple-joint. Fig. 4 is a View taken on the line 2 2 of Fig. 1. Fig. 5 represents a portion of the rim containing the lens broken away. Fig. 6 is an enlarged detail of the clamp used on the rim. Fig. 7 is a plan view of a section, showing a modified form.

In carrying out the invention, A represents the ends of the wire employed to form the entire rim. It is first bent to conform to the upper half of the lens, then outwardly, then at right angles, and back again to form an ear or projection A', then back to form the lower half of the lens,then gradually curved to form the nose-piece B and continuing around the other lens in the ,same manner as the first, and, finally, ending on the opposite side of the nose-piece, where it is securely fastened by means of a small clamp IJ.

C is the wire, which forms the bows and which also is bent to form the temple-joint.

A loop C' is bent in one end of this wire C, and this is passed through the projection A' from the outside and bent once around the wire, forming the projection A. The wire is then secured by winding tightly around the bow close to the temple-joint.

b2 is a clamp which is bent around the projection A to form an abutment for the loop C'. This serves to keep the bows adjusted to the desired position when open and prevents the loop C from coming into contact with the edge of the lens.

D, Fig. 7, represents another form of-my improved spectacle-frame, which is more simple and equally as effective as the one above described. In this I form the entire rim of a single piece of wire, and instead of providing the clamps as shown at Z)- 192 in Fig. 1 in bending the wire to form the projection at the outer end of the lens I am able to use the same wire by bending it to form a small loop d within the projection A', which will serve as effectually as an abutment for the templejoint loop C as the clamp b2. In this form of rim I am enabled todo away with the clamps b also by securing the ends of the eyewire A simply by tightly coiling them around that portion ofl the wire between the lower hal of the lens and the nose-piece, as shown at c It will thus be seen that I have provided a spectacle-frame which is exceedingly simple in construction and eective in application and have dispensed with all screw-fastenin gs,

rivets, &c., and making it practically impossible for the frame or temple-joint to get out of order. I do not desire to be limited to the specific construction shown in the drawings, as the details thereof might be changed without departing from the spirit of my invention, which consists, essentially, in providing 'a spectacle-frame composed of a single piece of wire bent in conjunction with the pieces of wire forming the bows to form the templejoint. v

Having thus described my invention, what I desire to secure by Letters Patent is-- l. Aspectacle-frame having the entire rim loop in one end of each of the bows bent Io formed of a single piece of Wire, projecting around the Wire of said projecting loops, and loops in each end of said rim, an elongated forming a hinge, substantially as described. loop on one end of each bow bent around the In testimony whereof l hereunto sign this 5 Wire of said proj eeting loop to form the hinge specification in the presence of two Witnesses. or temple-joint, substantially as described. WILLIAM E. BELT.
