DEFINITION

Classification: 351/71

(under subclass 65) Subject matter wherein the nose grips or guards are formed of resilient material or are combined with a spring to bias the guards with respect to the bridge to properly engage the nose and retain the glasses thereon.

(1) Note. In the modification here the guards may be actuated by flexible portions in the bow springs, by coil springs interposed between lens mountings and the nose-engaging member, or by moving the lenses forwardly against the resiliency of a bridge portion. However, for classification in this subclass the nose guards must be biased with respect to at least a portion of the bridge which remains rigid. A mere bridge of resilient material and flexible over its length is not provided for here but in the generic subclass 65 above.
