spectacles and eyeglasses, and has for its ob ject to provide an improved construction of nose guard or clamp.

My invention comprises a main blade or guard and a supplemental or auxiliary guard thereon adapted to anchor the main guard against displacement from the nose. The principal object of my invention is to provide means that will automatically raise up the flesh in front of the supplemental guard thereby tending to retain the guard in place on the nose and retarding displacement therefrom.

Another object of my invention is to provide nose clamps or guards which are more or less resilient or yielding whereby they will easily and comfortably adapt themselves to the nose.

I Vith these and other objects in view,'the invention consists in the novel construction and arragement of parts hereinafter de scribed, delineated in the drawings and specifically claimed, it being understood that changes properly falling within the scope of what is claimed may be made with out departing'from the spirit of my invention.

Similar numerals of reference are emdenote corresponding parts throughout the several figures of my invention.

guards in place on the nose, the nose and ridge of flesh in front of the auxiliary guard being indicated by dotted lines.

Referring Specifically to the drawings: A pair of'lenses 1 are connected in the usual manner by a bridge 2 and lens clip Nose guards 01' clamps 4: are carried on theends of levers 5 which are pivoted on the bridge ends at 6 and are operated by handles of fingerpieces 7 The nose guards are impelled toward each other by springs 8 which operate on the levers 5, being wound about the pivot 6.

The structure above described is the usual finger piece eyeglass and is well. known in the art. To the well known guard above described I add a supplemental or auxiliary guard 9, the face of which is disposed at an angle to the face of the main guard st in such a manner as to tend to raise a ridge of flesh in front of its free edge when in place on the nose, as indicated in Fig. XIII. The auxiliary guard may be made integrally with the main guard as shown in Figs. III and X'II or it may be a separate piece secured to the 'main guard as shown 'in Fig. XI. Where theauxiliary guard is made integral with the main guard an arm 1.0, Fig. III is provided between the main and auxiliary guards. This arm is then bent and looped so as to dispose the auxiliary guard at an angle with the main guard as shown in Figs. X and XII and at the same time provide a resilient fold 11, Figs. X and XII, tending to press the auxiliary guard toward the nose. If desired, although it is not necessary,:a stop 12 may beused to limitthe outward movement of the auxiliary guard; this stop comprises a tongue of metalintegral with the auxiliary guard and bentso as to forma hook engaging a portionof the The metal from which this stop is fashioned is pliable and consequently its length is adjustable by bending to accommodatevarious outward positions of the auxiliary guard. If desired the auxiliary guard may be made separate from the main guard and securely attached thereto as shown in Figs. VVI=I-VIII-IX and XI.

In Fig. V the auxiliary guard is hinged or pivoted to the main guard and a tongue 13 cut from the main guard acts as the resilient member pressing the auxiliary guard toward the nose.

The modification shown in Fig. VI is similar to the construction indicated in Fig. V with the exception that the auxiliary guard is integral with instead of hinged to the main guard.

The auxiliary guard in Fig. VII is hinged to the main guard as in Fig. V but the in tegral tongue 13 is replaced by an independent spring 14.

Figs. VIII and IX show two modifications wherein the auxiliary guards are riveted to the main guard. The auxiliary guard in Fig. VIII extends from its attachment directly toward the front edge of the guard, while in Fig. IX it extends first rearwardly, then forwardly forming a resilient and adjustable loop similar to loop 11 in Fig. X.

In operation the resilient member of the guard tends to force the auxiliary guard into intimate contact with the nose, the auxiliary guard being so angled that its front edge will tend to dig into the nose and raise a ridge of flesh in front of it as shown in Fig. XIII. When the guard is displaced forwardly on the nose the resilient member causes the auxiliary guard to follow up the contour of the nose and constantly resist displacement by its front edge digging in. The auxiliary guards will also tend to tighten their. grip on the nose when displaced forwardly due to the method of attaching the rear side of the auxiliary guard to the main guard, the front edge catching in the flesh of the nose and opening out the angle between the main and auxiliary guard, causing the free front edges of the auxiliary guards to approach each other.

The auxiliary guard may be faced or not as desired. Fig. IV shows in dotted lines a xylonite pad 15 attached to the auxiliary 'guard. This pad is shown in section in Figs. VVIVIIVIIIIX and X.

I have shown a main guard having a perforated portion, wherein the auxiliary guard is located, but it is not necessary to so perforate the main guard as the same effect can i be produced by attaching the auxiliary guard in similar manner to a non-perforated main guard. I have also shown my guard applied to finger piece eyeglasses but it may be also applied to the other forms of eyeglasses and spectacles wherein nose guards are used.

Various methods of arranging and placing the auxiliary guard may be devised without departing from the spirit of my in vention. I, therefore, do not desire to be limited to the exact details shown.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination with a main guard, of an auxiliary guard having its rear edge connected to the main guard to permit of relative movement of the main and auxiliary guards, said auxiliary guard having free front and end edges and means for resiliently forcing the front edge of the auxiliary guard outward relative to the main guard.

2. The combination with a main guard, of an auxiliary guard attached to the main guard to permit of relative movement of the main and auxiliary guard, said auxiliary guard having free front and end edges, means for resiliently forcing the front edge of the auxiliary guard outward relative to the main guard, and means for limiting the movement of the auxiliary guard.

3. The combination with a main guard, of a supplemental guard carried thereby, and means for resiliently forcing the forward edge of the auxiliary guard outward relative to the main guard a greater distance than the rear edge of the auxiliary guard.

4c- The combination with a main guard, of an auxiliary guard supported posterior to the anterior edge thereof and mounted for yielding movement relative to the main guard, and means for forcing the forward edge of the auxiliary guard outward relative to the rear edge thereof.

5. A nose guard for spectacles and eyeglasses comprising a main. guard having a perforation, an auxiliary guard in the perforation and resilient means uniting the rear edge of the auxiliary guard with the main guard.

6. A nose guard for spectacles and eyeglasses comprising a main guard and an auxiliary guard facing and disposed at anangle to the main guard, resilient means uniting the rear edge of the auxiliary guard with the main guard and means to limit the outward position of the auxiliary guard.

7. The combination with a main guard, of

an auxiliary guard disposed at an angle to the main guard, means attached to the aux- 1l1ary guard posterior of the anterior edge thereof for connecting the same to the main guard, and means for yieldingly holding" the forward edge of the auxiliary guard outward relative to the main guard.

8. In spectacles and eyeglasses a blank for a nose guard comprising a perforated main guard section, an auxiliary guard section, a

tongue uniting the main and auxiliary guard sections and a tongue extending beyond the auxiliary guard adapted to be bent into a stop.

9. A nose guard for spectacles and eyeglasses comprising a perforated main guard, an auxiliary guard within the perforation of the main guard, and an integral tongue extending from the rear edge of the auxiliary guard to the main guard substantially as shown and described.

10. A nose guard for spectacles and eyeglasses comprising a perforated main guard, an auxiliary guard within the perforation of the main guard and a resilient integral loop extending from the rear edge of the adapted to hold the auxiliary guard ex auxiliary guard to the main guard substantended beyond the main guard. 10
