'Specification of Letters Patent.

Application filed October 4, 1909. Serial No. 520,833.

speciiication,`and to the reference-numerals marked thereon.

The present invention relates to eyeglass mountings and it has for an object to provide f a construction in which the pupilary distance in a mounting having pivoted guards may be reduced to a minimum.

Another object fis, without rendering the `mounting conspicuous, to provide for increasing the length of the bearings for the pivoted guards in order to prevent the latter Wabbling on the mounting.

-, A further object is to make provision whereby the supporting arm of.a pivoted nose guard may be increased in length for the purpose of facilitating the adjustment of the guard. I l

To these and other ends the invent-1011 conwill be hereinafter more fully described7 the novel features being pointed outlin the top view underthe same co ditions.

claims at the end of the specification.

In the drawings: Fi ure 1 is an enlarged front view of a mount ng in which one of the guards has been removed. Fig. 2 isa Fig. 3 is a central transverse secti nal View. Fig. 4 is a perspective view of the support, and Fig. 5 is a perspective view of one ofthe guards. s l..

ln the present embodiment the lenses\A areconnected by a suppo'rt comprising pr`e\f erably a bridging portion 1 having its ends arranged-in rear of the plane of the lenses and connected to the lens) attaching devices 2 .45.by forwardly extending arms, each in this instance arranged in a vertical pla-ne with an end 0f the bridging porti'on transverse of the plane of the lenses and connected to the latter by a downwardl and forward bend.

The form of the support herein shown i permits the uards to be pivotally mounted` ,v in front of t 1e bridging portion s'o .that the distance between the centers of the lenses may be decreased. To this end the forward ends of the arms 3 may be enlarged in or:

der to provide horizontal seats 4 which may be perforated at 5 and have the walls of the perforations screw threaded to receive the screw threaded ends of pivot pins- 6 projectv 2 ends of the bridging portion so that the distance between the endsof the bridging porvtion and the edges ofthe lenses may be reduced.

Thenose guards which have particular 'advantages with a. support of the type described and have features also adapted for fuse on other types of supports, may each embody a nose engaging member With upper and lower pads or nose engaging surfaces 18"and 14 pivoted 'or otherwise secured at lG by an outwardly offset arm 15 to aver- 'tically offset seat 17 on a guard lever. The latter preferably embodies a supporting arm 10 operating beneath the support s0 as not Ito interfere with the end of the bridging 'portion and having the Seat 17 at its rear f end. The forward end of the supporting arm is connected toa bearing member 7 that Patenteaoct. 1,1912. y

turns in engagement with a seat 4 and also 'on a pivot 6 on the opposite or upper side of the support, this connection being estab` lished by a portion 11 which lies in fro'nt of the support and is provided with an out-l wardly extending operating portion or finger piece 12. The portion 11 with the supporting arm 10 and bearing member 7 forms a rearwardly opening loop which' may be bent to permit the nose engaging member to be raised and lowered or otherwise adjusted relatively to the bearing 7 a of the guard from a point in advance of the pla-ne of the lenses and of the turning axis of the guard. To prevent Wabbling of the guard carrier an auxlliary bearing member 9 is provided -which lies parallel with. the member `7 to `turn against the head 6a of the pivot pin the latter is bent at 30 transversely to provide bearing 9, thence transversely at31 to provide the upright or spacing portion 8 at right angles to the bearing 9, agai'nftrans-- arrangement the bearings 7a and 9a lie perpendicularly to the fiat face of the supporting arm 10 and the latter while having'a great deal of strength does not occupy much space Von the mounting.,

The springs 18 for positioning the guards may be of anyform. In this instance each is of helical formation and surounds a pin 6 between the bearings 7 and 9 with one end 19 bearing against the vsupport and the other end 2O formed into a hook engaging the guard.

To remove the mounting from the nose of a. wearer or to place it in position thereon, the finger pieces 12 are pressed together thus separating the .nose engaging members which, when the finger pieces are released,

move toward each other under the action of n springs 18.y

With eyeglasses constructed in accordance 2 with this invention the pivots of the guards 'may be located directly in front of the ends of the bridging portion of the support so that*` the length of the support may be reiduced to a minimum for a person having a short pupiliary distance. The bearings for y the guards are increased so that lost motion 40- is prevented, while the size of the mounting is notl enlarged to such an extent that it is rendered conspicuous and the length of the guard supporting arms is also increased 1 to give better. adjustment Without adding 45 materially to `the size of thev mounting. y

Byarranging the portionv 8 that connects the bearing portions 7* and 9 to one side of the plane of the lenses, or rather, spacing it from the pivot inthe direction of the length of the guard lever, as a whole, instead of laterally thereof, it is not only rendered inconspicuous butI tends to reduce pupiliary distance and hence this style of bearing support can be .used on any mounting without Wideningthe space or table between the 'archozffothebridge and the lens: attaching portion* beyond what is required to accommdatethe Width of the guard lever itself.
