Application filed April 3, 1914. Serial No. 829,242.
- ciency and shall present an attractive appearauce.
Figure I represents a i'raginentarv front view illustrating one embodiment of my invention. Fig. II represents a similar view illustrat ng another embodiment thereof. Fig. Ill represents a plan view of Fig. I. Fig. IV represents a plan view of Fig. II. Fig. V represents a sectional view on the line V--V of Fig. III. Fig. VI represents a plan view of one form of my spring such as is employed iii Fig. III, and Fig. VII represents a plan view of a spring such as is employed in Fig. IV.
In the drawings, in which similar characters of reference are-employed through ut to denote corresponding parts. the numeral l designates the bridge having at its end a clip 2 for securing in position the usual lens 3. Heated in the bridge is a pivot l on which swings the lever 5 bearing a nose guard or gripping member (i, these parts being of any usual construction and their particular Iea tures forming no part of the present invention.
To actuate the levers and thus t'oi-tetlie guards into satisfactory gripping engagement with the nose I employ my improved springs which comprise a helically wound portion 7 substantially circular in cross section inclosed by a wall 8 which is preferably of either I'lat or but partially round material and is as wi e as the length of the helix. as is most clear y illustrated in Fig. V.
In that form of my invention en'iployed in Figs. I and III, I have the terminal portion of the wall 8 resting against the strap or clip 2 to hold this end in position while the other end of the Spring extends outwardly and is tied around the lever 55.
30 it known that I, Joni. \VicnLs, a citizen oi the United States. residing at Southi I l i t i I t I i t i In that form of my invention illustrated in 1 Figs. II and IV and which is formed from the blank shown in Fig. VII, I reverse the position of the parts. the portion 7 having an outwardly extending end 9 resting against the strap and projecting across the edge of the portiono. the coils of the portion 7 be; ing inclosed by the portion 8 which terminates in the end 10 tied aroiindthe lever.
It to be noted in both of these forms of my invention the portion 8 serves a double purpose in that it not only forms a part of the spring and by resiliency aids inforcing the levers and guards into correct gripping position. but also on account of its shape it serves to inclose the coils of the spring,'p articularly when acting in conjunction with the screw head and the lever, so that the coil portion of the spring is protected from dust and dirt which would otherwise tend to clog the spring and also to spoil the appearance of the mounting. It will thus be seen that "in my improved spring I attain the efiiciency of the usual coil spring with the added efiieiency of the flattened portion thereof, while in addition to this the saidflattened portion presents an extremely neat and attractive appearance and. as before stated, serves as a dust guard toproteet and conceal the 0therwise somewhat unsightly coil spring.
I claim:
l. .\n actuating spring for eyeglasses comprising a central helieally wound portion and a wide inclosing band.
2. .\n actuating spring for eyeglasses comprising a central portion of substantially circular shape in cross section and an incl0s-' ing spring wall substantially rectangular'in cross section.
3. In an eyeglass mounting the combination with a support, a pivot rising therefrom. of a guard leverswinging on the pivot and an actuating spring for the lover comprising a coil wound on the pivot. said spring terminating in a wide portion bent to inclose the coil.
4. .\u eyeglass mounting including a support for the lenses. a lever mounted upon the support. a pivot for the le er carried by the support a spring coiled axially with the pivot and terminating in a widened portion inclosing the pirot and portion of the spring coiled directly thereon. said widened portion having its tree terminus ccuinectod to one of the two first named parts.
5. In an eyeglass mounting the combination with a support and a headed pivot carried thereby, of a lever mounted on the pivot, a helical spring coiled on the pivot between the lever and head, said helical spring ter- 5 minating in a wide portion inclosing the helical portion thereof and in engagement \Vitnesses: with the head. and lever, whereby said CHARLES I. KING, -,widened portion forms a protecting wall for I Prrr H. HERBERT. I
preventing access of dirt to the coils of the helix.
In testimony whereof I aifix my signature in presence of two witnesses.
