EYEGLASSES.

Application filed January 8,

To all whom it may concern:

Be it known that we, CLARENCE M. STE-- VENSON and NELSON M. BAKER, citizens of the United States, residing at Los Angeles, Los Angeles county, California, and Southbridge, in the county of \Vorcester and State of Massachusetts, respectively, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification.

Our invention relates to improvements in eyeglasses and is particularly adapted for use in connection with fingerpiece eyeglasses, although it may be used on other forms of eyeglasses.

The leadingobje'ct of our invention is the provision of an improved form of nose guard which shall be provided with free. front edge gripping portions for preventing slipping of the guard on the nose.

The further object of our invention is the provision of a nose guard which shall embody in addition to the ordinary bearing which may be adjusted to bite into the flesh at the side of the nose with any desired force and which shall aid in preventing: slipping of the guard.

Another object of our invention is the provision in conjunction with a guard of the character above described, of improved means for causing the biting in of said supplemental bearing portion automatically and of the provision of such means which may be readily adjusted to vary the initial position of the guard and supplemental bearing portion according to the peculiar con- 7 figuration of the nose of the wearer.

Other objects and advantages of our improved nose guard for eyeglasses will be readily apparent by reference to the following specification taken in connection with the accompanying drawings forming a part thereof, and it will be understood that we may make any modifications in the specific structure shown and described within the scope of the appended claims without departing from or exceeding the spirit of our invention.

Figure I represents a perspective view of a pair of eyeglasses equipped with my nose guards. Fig. II represents an enlarged perspective view of one of the guards illustrating a slightly modified construction.

1912. Serial No. 669,978.

Fig. III represents a fragmentary plan view of another form of my guard and supplemental bearing portion. Fig. IV represents a vertical sectional view of the device shown in Fig. III. Fig. V represents a sectional view taken on the line AA of Fig. III. Fig. VI represents a sectional view of a further modification of the invention. Fig. VII represents a sectional view taken on the line BB of Fig. VI. Fig. VIII represents a perspective view of the various parts constituting the guard shown in Fig. VI in disassembled relation. Fig. IX represents a view of my guards in engagement with a nose, illustrating in dotted lines the biting .of the free front edge supplemental bearing portions, and Fig. X represents a perspective view of my guard showing the same in its normal position and illustrating the same in dotted lines in its adjusted position. Fig. XI represents a stud box construction.

In the drawings, in which similar characters of reference are employed throughout to denote corresponding parts, the numeral 1 designates the lenses of an eyeglass connected by the bridge 2 and lens clips 3 in the usual manner. Said bridge 2 has the flattened portions 4 in which are engaged the pivot screws 5 having rotatably mounted thereon the flat portions 6 of the fingerpiece levers. Said fingerpiece levers have the twist 7 formed therein and the loop 8 adjacent said twist, the levers terminating in the enlarged cam heads 9.

In the various forms of our invention we have shown pivotally secured to the cam head 9 by the rivet 10 the ear 11 which is formed integral with the .main member 12 of my guard, said main member being preferably so disposed as to rest directly against the nose although in Figs. VI, VII and VIII, we have shown this main member as provided with a plurality of supplemental bearing portions 13.

In the preferred form of our invention, as illustrated in Fig. I, we form the main member 12 in the shape of a double loop, while extending as a continuation of one of said loops is the resilient portion 14: having an offset end 15 adapted to contact with the other end of the main guard member to limit the inward movement of the portion 14 relative to the memberlQ. In the use of the eyeglasses shown in Fig. I the fingerpiece levers are pressed together to separate the guards and the glasses placed on the nose. The springs 16 then serve to swing the levers and thus the guards are brought against the nose, the upper and lower portions resting firmly against the nose and the guard turn ing on the pivot 10 until it is in the best bearing position. As the main member 12 is swung on its pivot 10 the resilient portion ll which normally lies slightly back of the plane of the main portion is forced against the relatively stationary cam end 9 of the finger-piece lever and continued swinging movement of the guard will cause said cam head to force the portion M inward into biting engagement with the flesh of the nose, as is clearly illustrated in Fig. IX. This portion 1-1 having a free front edge satisfactorily bites and prevents forward slipping of the guard relative to the nose. In order to attain the most satisfactory biting of the said portion 14 after the position of the guard when in engagement with the nose has been determined, the loop 8 or the flat portion or twist of the fingerpiece lever may be bent as desired to vary the position of the cam head relative to the guard and thus to vary the amount which said cam head forces the portion. 14 inward.

In Figs. III, IV and V, we have shown the main portion 12 as having a supplemental bearing portion 14; cut central therefrom instead of at one edge thereof, while the body or main portion 12 is provided with a pair of ears 11, the cam head being pivoted between said ears and forcing the portion 14: inward in the same manner that portion 1a is distorted.

In the other modification shown in Figs. VI, VII and VIII, we have formed in the main portion 12 the apertures 17 in which are slidably engaged the pins 18 hearing on one end the bearing pads 19 and having their other ends riveted in the spring 14'. In this form of the invention the two bearing pads rest against the nose and regulate the position of the guard while the cam head 9 by hearing against the spring 14: serves to bow the same and thus to increase the pressing tendency of the pads, the pads either being adjusted together by swinging of the member 12 or independently of each other by yielding of the spring 14.

From the foregoing description taken in connection with the drawings, the construction and operation of our improved nose guard for eyeglasses should be readily understood, and it will be seen that we have provided a simple and eflicient guard in which the bearing of the upper and lower portions of the guard serves to adjust the position of the entire guard on its pivot support, while the operation of the cam end of the fingerpiece lever serves to press inward a resilient portion and thus to cause a supplemental pressure to the pressure given the guard as an entirety by the spring 16, while the free front edge of the supplemental member controlled by the cam head satisfactorily bites into the flesh to prevent slipping of the guard and the peculiar configuration of the inner portion of the finger-piece lever permits of any desired adjustment of the guard to regulate the pressure of the su iplemental bearing portion thereof.

lVhile we have described our invention as particularly adapted for use upon a finger piece mounting, this has been done merely because a finger piece is at present the type of eyeglass in vogue, but it will be under stood that our guard will prove equally desirable and identical in operation when used with spring bridge, bar spring or other forms of eyeglasses. In Fig. XI we have illustrated our device as used with a spring bridge 20 having its lower ends secured in the stud box 21, from which projects the arm 8 having the cam head which bears the guard, the construction of the guard and its supporting arm. being the same as in the other views except that the terminal end of the arm is adapted. for attachment to the stud box instead of being shaped into a finger piece lever.

'We claim:

1. A nose guard including operatively inter-related main and supplemental bearing portions and automatic means whereby the variation of pressure on one causes a variation of pressure on the other bearing portion.

2. A nose guard including a main bearing portion, a supplemental free front edge bearing portion and means for automatically forcing the supplemental free front edge bearing portion into biting engagement with the nose.

3. A nose guard including a main bearing portion, a resilient normally inoperative supplemental bearing portion, and means for forcing said resilient portion into operative position.

4. A nose guard including a main bearing portion, a supplemental bearing portion and a cam for forcing the supplemental bearing portion inward relative to the main bearing portion.

5. A nose guard including a main member having an ear, a lever having a cam head pivoted to the ear, and means carried by the main member and engaged by said cam head for biting into the nose as the main member is swung on its pivot.

6. The combination with a pliable support capable of universal adjustment, of a guard pivoted thereto having a supplemental hearing portion whose pressure is adjusted relative to the pressure of the main bearing portion of the guard by adjustment of the pliable support, the support having a projection engaging said supplemental bearing portion for attaining said adjustment.

7. A nose guard including a main member, a resilient portion integral with said member and a cam pivoted to the main member and engaging the resilient member to force the same inward relative to the main member.

8. A nose guard including a main bearing portion, a supplemental bearing portion and a cam like support pivoted to the main bearing portion in such a manner that swinging of the main bearing portion for adjustment to a nose will throw the supplemental portion into engagement with the cam and cause the cam to force said supplemental portion inward relative to the main bearing portion.

9. The combination with a nose guard arm having vertical and horizontal portions and terminating in a cam shaped head, of a nose guard having an ear pivoted to said cam shaped head and having a resilient portion resting against the cam face of the cam shaped head whereby swinging of the guard on its pivot will cause the cam to force the resilient portion inward relative to the main guard.

10. The combination with a nose guard 30 arm having vertical and horizontal portions and terminating in a cam shaped head, of a nose guard having an ear pivoted to said cam shaped head and having a resilient portion resting against the cam face of the 35 cam shaped head whereby swinging of the guard on its pivot will cause the cam to force the resilient portion inward relative to the main guard, and an offset portion formed on the resilient portion of the guard 40 and adapted to engage the main guard to limit the inward movement of said resilient portion as caused by the cam.

In testimony whereof we afiix our signatures in presence of two witnesses.
