GEORGE` W. WELLS, OF SOUTHBRIDGE, MASSACHUSETTS.

EYEGLASSES.

SPECIFICATION formingpart of Letters Patent No. 689,664, dated December 24, 1901.

Application tied Apiii 29, 1901.

To all whom t may concern:

Be it known that I, GEORGE. W. WELLS, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification.

My invention relates to eyeglasses, and more particularly to the post in which are secured the end of the bow-spring and the end of the nose-guard. v

In the ordinary construction of the post in eyeglasses the inner end is slotted or recessed to receive the end of the bow-spring andthe end of the nose-guard, and a screw extends loosely .through holes in said ends and is screwed into the post to secure the parts together. In this construction of the post the lianges or walls on the end of the post from overstrain or lack of strength are liable to spread suiiiciently to allowT of a slight movement of the end of the bow-spring and the end of the nose-guard edgewise. This movement will tend to turn out the screw and loosen the parts. l

The object of my invention is to prevent any spreading of the 'anges or walls on the end of the post, betweenwhich the end of the bow-spring and the end of the nose-guard ex` tend, and consequently any edgewise movement of the bow-spring and the nose-guard to cause the holding-screw to be moved out and the parts loosened.

In my improved construction of the post I preferably make the inner end of the post without the usual projecting iianges, between which the bow-spring and nose-guard extend, and I provide a rigid or solid cap or end for the post of the same width as the post and having sides extending down over the sides of the post and soldered thereto to form an 'aperture or opening at the end of the post to screw to come in contact with the end of the Serial No. v5 7,919. (No model.)

My invention consists in certain novel features of construction of my improvements in eyeglass-posts, as will be hereinafter fully described.

Referring to the drawings, Figure l is a front view of an eyeglass having eyeglassposts embodying my improvements. Fig. 2 is a vertical section through the post shown in Fig. l, Fig. 3 is an end view of the parts shown in Fig. 2 looking in the direction of arrow a, same iigurc. Fig. 4 is a horizontal sectionthrough the post at a point indicated by lines 4 4, Fig. 3, looking in the direction of arrow b, saine ligure. Fig. 5 corresponds to Fig. ,4; but the nose-guard, bow-spring, and screw are not shown. Fig. (S corresponds to Fig. 5, but shows a modified construction of the post. Figs. 2 tov, inclusive, are on an enlarged scale.

In the accompanying drawings, 1 vrepresents the lenses, which in this instance are shown as rimless. Y

2 represents the posts, each of which has a pair of attaching lugs or ears 2', between which the inner edge of' the lens l extends, and is secured in place by a screw 3 in the ordinary way. A

4 is the bow-spring of any ordinary shape, and 5 the nose-guards, which 'in this instance are shown as offset and provided with an attaching-arm .5.

I will now describe the construction of the post to which, as above stated, my invention particularly relates.

The inner end of the post 2 is made without the usual projecting lips or flanges, forming a recess to receive the end of the bowspring and the end of the arm on the noseguard. A cap 6 ofthe same widthA as the end of the post, as shown in Fig. 3,'and `preferably made of sheet metal, with its two sides 6 bent at right angles to the end, is fitted onto the end of the post 2, and the sides 6 of the cap 6 soldered to the sides of thepost 2 to rigidly secure the cap thereon and leavean aperture or opening 7, as shown in Fig. 5.

Within the opening 7 extends the end of the IOO bow-spring 4 and the end of the supportingarm 5' on the nose-guard 5, as shown in Fig. 2. The end of the cap 6 has a central opening 6" therein, and a binding-screw 8 extends loosely through said opening G" and through a hole in the end of the supporting-arm of the nose-guard and in the end of the bow-spring, with its head extending loosely in the opening 6" in the cap 6. The screw 8 is screwed into a threaded hole 2" in the post 2 to cause the head on the screw 8 to bear against the end of the supporting-arm 5 on the nose-guard 5 and secure said end and the end of the bowspring within the aperture or opening 7 in the post, as shown in Figs. 2 and 4.

It willbe understood that the details of construction of my improvements in eyeglassposts may be varied, if desired. For example, the post may be made in the usual way, as shown in Fig. 6, with the ilanges 9 on its inner end, between which the end of the noseguard and the end ot' the bow-spring extend, and a cap or plate 6, having a central opening 6a therein, soldered or fastened on the end of the iianges to form the opening 7, corresponding to the opening 7 shown in Fig. 5.

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

1. An eyeglass-post, a nose-guardand bowspring, a cap having side apertures or openings to receive the ends ofthe nose-guard and bow-spring, said cap being also provided with a central opening, and ascrew passing loosely through said central opening and bearing directly on the nose-guard or bow-spring for clamping the same between the end of the post and head of the screw.

2. An eyeglass-post, a nose-guard and bowspring, a cap having its sides fitted about the end of the post and secured thereto, said cap having a central opening and an aperture or opening to receive the end of the nose-guard and bow-spring, and a screw for securing the nose-guard and bow-spring within the cap, the said screw passing loosely through said central opening and binding the noseguard and bowspring between the head of the screw and end of the post.

3. An eyeglass-post, a nose-guard and bowspring, a cap having its sides fitted about the end of the post and soldered thereto, said cap having a central opening and an aperture or opening to receive the end of the nose-guard and bow-spring, and a screw for securing the nose-guard and bow-spring within the cap, the said screw passing loosely through said central opening and binding the nose-guard and bow-spring between the head of the screw and the end of the post.
