SPECIFICATION forming part of Letters Patent No. 739,855, dated September 29, 1903.

Application file d February 9 1901- Serial-1N0. 46,684. '(No model 7 T0 at whont it ntay concern:

Be it known that I, CHARLES GOODWIN, a citizen of the United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Eyeglass-Mountings, of which the following is a specification.

This invention relates to improvements in eyeglass-mountings,and particularly to means for assembling and securing the extremities of the spring and the nose-guard.

The principal object of the invention is to provide simple and elfective interlocking devices for reliably and positively holding the spring and the terminals of the nose-guard members and by preventing their working loose avoid the annoyance of accidental de tachment and loss of parts.

A still further object of the invention is to provide a device of this character in which the spring member isprovided with a pair of alining securing devices formed by making indentations in one side of the spring, the displaced metal forming projections at the opposite side of the spring,,while the adjacent faces of the stud and nose-guard member are provided with means for engaging such depressions and projections.

With these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter described,illustratedin the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size,

and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective view of an eyeglass-mounting embodying the features of the invention. Fig. 2 is a sectional elevation of a portion of themounting drawn to a somewhat larger scale in order to more clearly illustrate the invention. Fig. 3 is a side elevation of a portion of'the mounting, illustrating a slight modification. Fig. 4 is a view similar to Fig.

2 with the parts constructed in the manner shown in Fig. 3. Fig. 5 is a detail perspective View of one end of the spring detached. Similar numerals of reference are employed each end of the spring.

to indicate corresponding parts-throughout the several figures of the drawings.

In the drawings, 1 designates the usual studs,havingclips forsecurementtothelenses 2, 3 the spring,-and t-the nose-guards, having supporting-arms 5. The inner face of each stud is preferably provided with edge flanges to form a box-like structure, or it may be made without flanges, as shown in Fig. 3. The nose-guards may be supplied with the usual pads or strips 8 and arranged at any desired angle to the lenses.

In the construction shown in Figs. 1 and 2 the base of each stud is provided with rounded opposite sides of the spring-terminals, and

these projections are received in indentations 12, formed in the outer sides of the supporting-arms 5 of the nose-guards, the terminals of the spring and the arms being held between the side flanges of the stud and the several parts finally secured by screws 13, arranged centrally between the projections and indentations, as clearly shown in Fig. 2. This arrangement provides a positive securement for the several parts that will prevent them from working loose and in a great measure relieve the strain or friction on the single screw at It furthermore insures accurate assembling of the parts.

The construction embodied in Figs. 3 and 4 is in all particulars similar to that just described with the exception, as before indicated, that the heads of the studs, are minus the side flanges, which form the box-like structure for the reception of the spring and noseguard arms. The same reference-numerals have been used in these latter figures as in Figs. 1 and 2 to denote similar parts.

It is obvious that when the screw is turned in tightly that the several notches and indentations will be held firmly in engagement with each other and all tendency to loosen ing of the parts will be prevented.

Having thus described the invention, what is claimed is 1. In an eyeglass-mounting, a stud having a spring-engaging face provided with vertically-alining projections, a nose-guard member having a spring-engaging face provided with aiining recesses, a spring disposed between the stud and the nose-guard and provided in one side with indentations that form projections on the opposite side of the spring, the indentations receiving the projections of the stud and the projections of the spring fitting within the recesses of the nose-guard, and a securing-screw for clamping all of the members together and interlocking the same by the engagement of said projections and recesses, substantially as described.

2. In an eyeglass, the combination of a lensholding clip with an inner vertically-disposed head in the form of a box and having upper and lower vertically-alined projectionsin the bottom thereof, a straight spring extremity directly applied to said box and having corresponding recesses in longitudinal alinement to receive said projections in the bottom of the box, projections on the inner side thereof similar to those of the box, a nosepiece arm bearing against the inner side of the spring extremity and provided with recesses to receive the inner projections of the spring extremity, and a screw extending centrally between and clear of the said projections to firmly bind the said parts and prevent them from having lateral movement on each other.

In testimony that'I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

CHARLES GOODWIN.
