will whores concern.-

itlrnown that I, Crrasrns A. HOFFMAN, Qneapolis, Hennepin county, Minnesota,

vents certain new and useful linnientsl yogi ssldountings, of which owing 1s a specification.

invention relates to mountings departicnlarly for eyeglasses 5 and the t of the invention is to dispense with all pin, and rivet holes, which weaken the 1.1:all at the point of greatest strain, oio. solde ng and brazing, which the heat has a tendand elasticity of suitable for the ivl a mounting 't few parts o UHllJlECi. i rally in. a corn: or iins" ant, no"eguard formed 'ention consists in providiridge nose-guard that is L u: ted on the lens. Further, We tion consists in various constrnctirms 1 combinations, all as heredescribed, and particularly pointed A'e claims. I e aeoonipany drawings, forming part of this specific: on, Figure l is a rear *iew of an enla ged eyeglass-mounting embodying my invention. Fig. 2 is a top View of san'ie. l 'g. 8 a plan view of the a". no ar lbs or being bent into 4. is a g toward the all sectional securing the Fig. 6 is a J .b rins the conanr. bridge. 2 represents the lens, each i lates 3}, adapted to m. the other and ad-' one end by .n the plates.

J around the 3d thereto by are provided in the f strap 6 to resurface of the h .es tor the one- I and nose-guards, as hereinafter The bridge or s ring 11 and the r d with a clamp consisting,

nose-guards 12 are stamped out of one piece,

preferably sheet metal, and bent into the desired shape to form the mounting. The parts 13 of the bridge between its curved middle portion and the guards are adapted to fit in between the straps 3 and be clamped thereby when the screws 4 are tightened, the points 9 preventing vertical movement, but allowing the bridge and guard to be slipped horizontally back and forth toward or from the plane of the lens to fit the mounting to the contour of the nose. This form of clamp dispenses with screws or rivets, which are liable to wear and work loose, and avoids all necessity of brazing or soldering any of the parts. Between the nose-guards and the parts 13 finger-pieces 14 are provided that are bent inwardly, as shown in Fig. 2, to enable the wearer of the glasses to easily place them on the nose or remove them.

The plateirom which the bridge or spring and guards are made can be bent into various shapes to lit the nose of the person for whom the mounting is made and to suit the taste of the Optician or customer and cause the lens to hang in anormal position, or lower forreading purposes, or higher for distance vision, or, in fact, any position that best suits the needs orwishes of the purchaser.

, The bridge and guards are not perforated at any point, and thus weakening of the mounting at such places that are subject to the greatest strain is avoided.

.The clamp may be stamped out of sheet metal, as shown, or ma be made in several pieces, ifpreierred. All brazing and soldering of the bridge and guard bein avoided, the inherent stiffness and elastic ty of the metal comprising the bridge and guard are retained.

I claim as my 1nvent1on- 1. in an eyeglass-mounting, a bridge an nose-guards formed from a single plece of metal, the middle portion of which is curved.

to ,i'orni the bridge and provided with for" wardly-eirtending end loops, the ends of said loops being inwardly turned and extended rearwardly substantially parallel with. one,

another to form the guards and finger-pieces projecting forwardly from said ends, substantially as described.

2. In an eyeglass-mounting, a bridge and nose-guards formed from a. single piece of metal, the middle portion of which is curved to form the bridge and provided with forwardly-extendihg end loops, the ends of said parallel with one another to form the guards,

and finger-pieces projecting forwardly from said ends, substantially as described.

4. In an eyeglass-mounting, the combination, with a bridge and nose-guards formed in one piece, the middle portion of which is bowed or curved to form the bridge and the ends inwardly turned and rearward ly extended to 01111 the guards, and clamps secured to the lens and wherein the bridge and guards are slidably supported to permit their horizontal adjustment with respect to the vertical plane of the lens.

5. In an eyeglass-mounting, a lens-clamp comprising a plate having oneend folded over upon the other and adjustably secured thereto, a space being provided between said ends wherein the bridge is clamped, and straps provided on opposite sides of said plate and adapted to be bent toward each other to straddle the lens andbe secured thereto, substantially as described.

6. In an eyeglass-mounting, a lens-clamp comprising a plate having its ends folded together with a space between them, a series of teats or points being formed on-one end of the plate to enter depressions-in the other end and form guides for the bridge, means for drawing the ends of said plate together to clamp the bridge, and straps provided on said plate and adapted to straddle the lens and be secured thereto, substantially as described. 4

In witness whereof I have hereunto set my hand this 7th day of November, 1904.

CHARLES A. HOFFMAN.
