2. In eyeglasses the combination with a bridge and the lens-holder, of a post connected with the lens-holder, a guard having two separated, apertured ears through which the post passes, a spring coiled around the post on one side of its connection with the lensholder, means for forming a stop for the spring in one direction, the other extremity of the spring engaging an ear of the guard and having a tendency to push it off the post, and means engaging the opposite ear of the guard to prevent the guard-ear acted on by the spring, from being disengaged from the post by the spring, the arrangement being such that by pressing one ear against the spring, the other ear may be disengaged from the post, and the guard readily detached.

3. In eyeglasses the combination with the bridge and lens-holder, of a post mounted on the lens-holder, a guard provided with separated, apertured ears through which the extremities of the post pass, a spring coiled around the post, a stop on the post engaging the spring at one extremity, the other extremity of the spring bearing against an ear of the guard, and having a tendency to push it off the post, and a stop connected with the post and engaging the other ear of the guard and arranged to hold the guard in place on the post in opposition to the tendency of the spring.

4. In eyeglasses the combination with a bridge and a lens-holder, ofa post made fast to the lens-holder, a guard provided with separated apertured ears, said ears being in sliding engagement with the post, a spring coiled around the post, a stop connected with the post and engaging one extremity of the coil, the other extremity of the coil bearing against one ear of the guard, and a stop connected with the post and engaged by the other ear of the guard,the arrangement being such that the expansion of the spring holds the guard in place 011 the post, while its torsional force is exerted to throw the guard toward the bridge whereby it grasps the nose of the wearer.

5. In eyeglasses the combination with a bridge and lens-holder, of a post mounted on the lens-holder, a guard provided with two separated, apertured parts forming bearings for the post and slidable thereon, a spring coiled around the post, a stop for one extremity of the coil whose opposite extremity engages a bearing of the guard, and a stop against which the opposite bearing of the guard is held by the action of the spring.

6. In eyeglasses the combination with a bridge and lens-holder, of a post mounted on the lens-holder, a guard having separated, apertured parts forming bearings which are slidable on the post, a spring coiled around the post between the guard-bearings, one extremity of which engages the lens-holder, while the other extremity bears against the guard, a stop for one extremity of the coil whose opposite extremity engages a bearing of the guard, and a stop against which the opposite bearing of the guard is held by the action of the spring.

7. In eyeglasses the combination with a bridge andlens-holder, of a post supported by the lens-holder, a guard having two separated, apertured parts forming bearings for the post and slidable thereon, a spring coiled around the post and engagingatone extremity, one of the bearing parts of the guard, a stop which the opposite extremity of the spring engages, and a stop against which the other bearing of the guard is held by the spring, the arrangement being such that as pressure is applied to the bearing engaged by the spring, the other hearing may he slipped from the post.

8. In eyeglasses the combination with a bridge and lens-holder, of a post mounted on the bridge, a guard mounted on the post and having two separated arms terminating in nosepieces, said arms being spring-pressed toward the bridge, the guard having two separated bearings engaging the post, a spring coiled around the post and having one extremity engaging one bearing of the guard, a stop against which the opposite extremityiof the spring bears, and a stop against which the other bearing of the guard is held by the expansive action of the spring, the arrangement being such that if pressure is applied to the bearing engaged by the spring, the other bearing may be detached from the post.

9. In eyeglasses the combination with a bridge and a lens-holder, of a post mounted on the lens-holder, a guard provided with two separated apertured parts forming bearings for the post and slidable thereon, a spring coiled around the post, a stop on the frame preventing longitudinal movement of the spring, said spring engaging a bearing of the guard, and a stop against which the opposite bearing of the guard is held by the action of the spring, substantially as described.

10. In combination with a pair of lenses and a bridge, a pair of upright pivots one at each end of the bridge, a nose-guard journaled on each pivot and consisting of a handle portion lying in front of the bridge and adjacent lens and a pair of arms extending inwardly and spread apart to straddle the bridge and provided with bearing-tips at their extremities, and springs pressing the tip-carrying ends of the arms toward each other.

11. The combination with a pair of lenses and a bridge, of a pair of upright pivots mounted on the bridge, a nose-guard journaledon each pivot and consisting of a handle portion lying in front of the bridge and a pair of arms extending inwardly and spread apart to straddle the bridge and provided with bearing-tips at their extremities, and springs pressing the tip-carrying ends of the arms toward each other.

12. The combination with a pair of lenses and a bridge, of a pair of nose-guards pivotally mounted on the bridge, each nose-guard iwardly and spread apart to straddle the l bridge, said arms being provided with bear- ;ing-tips at their extremities, and springs pressing the tip-carrying ends of the arms toward each other.

In testimony whereof I affix my signature in presence of two witnesses.
