Be it known that I, WAYNE S. Snnnnns, a

citizen of the United tates, residing at and State oflthode Island, have invented certain new and useful Improvements in Eyeglass l tlountings, or which the following specification.

This invention relates to improvements in eyeglass or spectacle mountings, and has for its object to provide in such a mounting aspring-pressed guard member having a bearing-collar about its pivot opening, a sleeve beingmounted 111 said opening havi5 ing an enlarged spring bearing portion 1 above the collar so that the upper coil of the spring which is practically supported against rotation is in contact therewith and pivot post being arranged to extend through the sleeve and be secured in the bridge portion of the mounting,

With these and otlerobfects in view, the inventionconsists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a side elevation partly in section showing a portion of an eyeglass frame with my improved construction for the support of thespring mounted thereon.

Figure 2 is a top view sectioned just under the head of the pivot post.

Figure 3 is a side elevation of the sleeve which embraces the post and extends down inside of the collar on the guard-member.

Figure 4: is a view showing a modified construction of pivot post receiving sleeve mounted in operative position.

Figure 5 is a sectional elevation of the modified form of sleeve detached.

to a height to receive but a portion of the coils of the spring, and to provide an addinrnennss nonnative.

Application filed April 26, 1922. Serial No. 556,594.

tionallbearing surface for the upper coils which I haveaccomplished bythe provision p p p L of a sleeve having an enlarged portion ofa Providence, 1n the county 01: Providence diameter substantially equal to that of the collar, and the following a detailed deterial from the plane of the stock providing a collar 14 oil a height equivalent to a predetermined number of superimposed coils of the helical s 'iring 15 which in this particular instance is suiiicientto receive three coils of the four-coiled spring.

By drawing up this collar from the stock .to this particularheight the same may be accomplished by a single drawing operation whiletwo or more drawing operations would be necessary to extend the collar another twenty-five (25) per cent higher.

Then again this member is adapted to be pivotally mounted upon the saddle portion of the bridge 16 and in this collar portion I have mounted a sleeve-member 17 having an enlarged port-ion 18 at its upper end, having an outer diameter substantially the same as the collar 14L, its enlarged portion being of a width equaling substantially that of the diameter of one of the coils of the wire spring which surrounds it.

In order to pivotally mount this fingerpiece mounting upon the bridge member, I have provided a pivot-post 19 screw thread ed at its lower end 20 into the bridge-memher and this post is provided with an enlarged head 21 above the sleeve to hold the whole in place.

By my improved construction which pro vides for the sleeve 17, I am enabled to employ the standard or stock screw 19 to serve as a pivot post and the sleeve with the enlarged head serves to fill in the space between the upper end of the collar 1% and the head, to provide room for the upper coil of the spring, the shank portion of the sleeve serving as an elongated bearing to prevent excessive wear by the rotation of the sleeve in the collar and on the post.

The device is extremely simple and practioal in construction and by its use the necesslty of drawing the collar on the finger piece to the full height necessary to receive all of the coils of the spring, is obviated.

In some instances instead of forming the collar portion 18 in the sleeve 17 and positioning the sleeve inside of the collaron the guard member I place the sleeve on the out side 01 the collar and form the enlargement on the inside of the sleeve as at 22, see Figures 4 and 5, which enlargement or thickened portion also serves to fill the space between the top of the collar 14 and the head 21 of the pivot post 19.,

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended clalms.

I claim:

1. In an eyeglass mounting, the combination with a pivotally mounted springpressed guard member having a bearing collar about its pivot opening, a sleeve extend ing through said collar'and having a springbearing portion above said collar, a pivot post extending through said sleeve, and a spring coiled about said collar and sleeve, its sleeve engaging end being relatively fixed against rotation and the opposite end of the spring being connected to said guard to move therewith.

2. In an eyeglass mounting, the combination with a pivotally mounted springpressed guard-member having a hen ring collar about its pivot opening, a sleeve exten ling through said collar, and having a spring bearing portion above said collar of a diameter substantially that of the outer surface of said collar, a pivot post extending through said sleeve, and a spring coiled about said collar and sleeve having its upper end fixed and its lower end positioned to act upon said guard.

3. In an eyeglass mounting, the combination with a body member, a pivotally mounted spring-pressed guard member having a bearing collar about its pivot opening. a pivot post extending through said collar having a head at one end spared above said collar, the other end of said post being threaded into said bridge, a sleeve surroululing said post and having a thickened wall portion filling the space between the top of said collar and post head, a pivot postextending through said sleeve, and a spring coiled about said collar and sleeve having its upper end fixed and its lower end positioned to act upon said guard.

In testimony whereoi I afiix my signature.

WAYNE S. S'EAR'LES.
