My invention relates to eyeglass mountings of the swinging guard arm t -yp'e',a'nd

rovide a convenguard relatively to the plane of the lenses, also transversely thereto; to provide a simple device for interlocking the guardand arm and which will prevent excessive rotary travel of the guard relatively to the arm;

to enable the guard and arm to be tightenedafter continued wear without binding the parts, and to facilitate the assemblage and connection of the guard and arm.

To the above .ends primarily my invention consists in the construction, cor'nbinzr.

tion, and mode of operation of parts set forth in and falling within the scope of the claimshereto appended.

In the accompanying 'drawings'iwhich form a part of this specification, Figure 1 is a rear elevation of a pair of eyeglasses embodying my invention, showing the lenses partially broken away, F1g. 2, a plan'vlew of the same, 3, a section taken on line' m of Fig. 2, Fig. 4, a vertical section of the screw in original form, showing in bro- ,ken lines its final form, and Fig. 5, a side elevation of the screw with the guard ear shown in sect-ion.

Like reference characters indicate like parts throughout the views.

above the plane of said face, as at h, andthen downwardly, as at it, forming avertical loop H opening downwardly. The vertical portion I of the armtermi natcs ina curved 'portionJ provided with 'an arcuate screw shank, but this is not essential. In detail this screw comprises a head having a flat bottom face 7c and an annular V shaped "groove 70 in its side. The screw shank has a smooth upper portion 71: and threads 10* upon its lower portion, the wholeadapted to -enter the opening Eachlfuard L has intermediate its length an ear of curved outline provided with an inturn ed marginal lug orprojection N adapted to register in the slot 9', and has also a circular opening 0 having a double'taper which is formed by an annular V shaped rib 70 within the opening registering in the V shaped groove 11 0f the screw head. The,

ear M isslidable or rotatable around the;

ter is in the plane of the. inner face of the ear M. A convenient method of uniting the de scribed screw head with the member M is illustrated in Fig. 4. The original form of the head is therein shown in full lines, and its final form, produced by a swaging tool, shown in broken lines.

The operationof the guards, is performed in' the usual wellknown manner and need not be described The upwardly directed loop not onlv affords ample inaterialandspace for ad ustment or the guards in all directions but 10 cates the bend above the plane of the supporting portion of the bridge where it is readily accessible for adjustment. I The peculiar construction of the screw K .makes its'head a permanent part of the member M, although loose therein, thus facilitating the assembling of the parta by making'it no longer necessary for the opera tor tosimultaneously control three separate parts while inserting the screw. Furthermore, the smooth portion of the opening 5,

serves to automatically guide the screwv to its threaded portionwithout danger of cross-. ing threadsv and prevents the screw from dropping out during adjustment. 5N has limited rotary movement in theslojt j which allows the gnardL-to'accommodate titself to'a degree to themose. If, howeyen;
