EYEGLASS-MOUNTI'NG.

pecification of Letters Patent,

Application filed .Tuly 27, 1911. Serial No. 640,917-

To all whom. it may concern:

Be it known that I, JOSEPH ROSENBL.-.\T1,

a. citizen of the United States, residing at Providence, in the county of Providence and'State of Rhode Island, have invented certain new and useful. Improvements in Eyeglass-Mountings, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to eyeglass mountings' of the class in whichv the grips are moved toward the nose by resilient means and are separated by manually operable portions, and the object of the invention is to provide simple andeffective means whereby the different styles of lens clamps may be rendered easily removable from the bridge member and interchangeable, and to form an.

interlockin key or spur on the bridge member adapte to enter a corresponding recess in the lens clamp whereby when these members are bolted'together'they are rigidly held and one cannot move upon the other.

A further object of the invention is to provide a. stud which performs the function of bolting the members togetherand at the same time serves the purpose of a pivot post on which the nose grips may'swing.

With these and other objects in view, the

-' locking spur on the bridge member engaging the correspondingly shaped aperture in the lens bracket. Fig. 3- shows a lateral offset connectfl to the-bridge member. Fig. 4- shows a vertical offset connected to the bridge member.

Referring to the drawings, 1 designates the bridge member which is formed separate and independent from the rest of the mount-' ing having'the usual archand being also provided with enlarged and flattened end portions 2-.-2, eachhaving a hole 3- for the reception of the fastening bolt hereinafter described. -An outwardly extending tongue or spur 4 is formed on the outer edge of each enlarged portion 2, said spur being ratentea'a r,"zeile'is.

preferably formed tapering, wedge-shaped 2.;

or having converging side walls 5-5.

The lens clamp members .6 are formed separate and independent .of-the, brid member and are provided withthe-usua'l fork portions 7 between which the lens-8 is secured by means of the screw .9. ,,Each' clamp is provided with anoutwardlya-em tending ear 10 corresponding; in size and shape and adapted to register .with the enlarged portions 2 on theends-of;the brid e. member This ear is pierced and p'refrab y threaded for the reception. of-' the;bolt aor securing stud 11. Each'lens clamp is pro f vided with a' recess 12 preferably havin'g diverging sidewalls, see Figs. 2 and, 3, into which the correspondingly wed e-shaped spur 4. on the bridge member is adapted to fit tightly. Each lens clamp may be secured to.its end of-the bridge member by means of a small screw or bolt such as that illustrated at 13, in Fig. 1, but I referably. use a stud illustrated at 11 in *ig; 1 the same being threaded through the ear or the lens clamp and provided. with a check nut 14 at its lower'end said stud having an enlarged bearing 15 above to serve as a pivot post on which the nose grip (not shown) may SWlIlg.

geo

It is understood that the essential reason for removably securing the lens clamps to the bridge member is so that the-different styles of lens clamps, such as the lateral offset either in or out, or the vertical ofi'set either up or down of all dimensions may be used whereby universal adjustment of the,

lens may be obtained to suit all requirements.

It is found in practice almost impossible in eye glass mountings of this character to connect and hold the lens clamp firmly in position by the use of a bolt alone, without the employment of additional means for keying the two members together. I have therefore devised this simple, effective and inexpensive locking method which is that of providing a wedge-shaped spur 'or tongue adapted to fit into acorrespondingly shaped recess in the opposite member whereby when a the two members are placed to other this spur naturally enters and we ges itself firmly into its recess so that when the binding bolt is passed through and-set up against the engaging ears the two members'are as rigidas though they were formed in one. An advantage of this construction aside from its great holding capacity is that-both the spur and the recesses may be formed by die work without the necessity of further finishing the walls of either in order to make them fit and hold perfectly.

I claim:

1. An eye glassmounting comprising a bridge member, a-pair of lens clamp members, an integral interlocking tapering spur on one of said members engaging a corresponding recess in the opposite member and ascrew for securing a lens clamp to each end of said bridge said screw also serving as a pivot post on which the nose grips may swing.

2. An eye glass mounting comprising a of said bridge said screw also serving as a pivot post on which the nose grips may swing.

3, An eye glass mounting comprisin a bridge member having enlarged and flattened ends, a lens clamp having a corre spondingly formed ear, a stud for securing a lens clamp to each endof said bridge, said stud also serving as a pivot poston which nose grips may swing, a tapering interlocking spur integral with and project-"' ing from each end of saidbridge into a correspondingly formed recess in said lens clamp whereby the latter are firmly held from turning on the former.

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