. EYEGLASS-MOUNTING.

,and useful Improvements in Eyeglass ltlountings; and I do hereby declare the following to be a full, clear, and exact desoription of the same,--reference being had to the accompanying drawings, 10'

forming apart of this specification, and to the reference numerals marked thereon.

The present invention relates to eyeglass mountings and this application is a division of an application filed by me on June 2-1, 1907, Serial No. 380,027.

An object of the invention is to provide an improved mounting which will have a and be adapted disconnection so that the opti'cian may rapidly change the guards in fitting the glasses to the customer.

Another object of the invention is to provide a construction which shall have its parts so located thatthef mounting will be inconspicuous upon the wearer.

Still another object'is to provide a construction in which bearings of maximum size may be provided for the nose guards without rendering the mounting conspicuous.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features bcing pointed outi in the claims at the end ofthe specification.

In the drawings: Figure 1 is an enlarged top view of a mounting constructed in accordance with this invention, the lenses being shown as attached but broken away at their outer ends. Fig. 2 is a' front View of the same mounting partly in section. Fig. 3 is a vertical central section transverse of the plane of the lenses. Fig. 4 is a detail view of one end of the mounting with the guard removed, and Fig. 5 is a'detail view of one of the guards. I

In the embodiment of the invention herein illustrated, the support for the lenses A comprises an arched or bridging portion 1,

preferably connected to the arched or bridging portion 1 by horizontal connecting portions 3 formed by providing arms on the blank Specification of Letters Patent.

Original application filed June 21, 1907, Serial No. 380,027. Divided and sem no. 526,094.

each having Patented Feb. 27, 1912. this application filed November 3,

from which the bridging portion 1 is made and rolling said arms to provide vertical bearings 4, the arms being soldered or other wise secured to the lens attaching devices 2. Arranged to operate on the support are nose guards comprising preferably levers a finger piece 6 at its forward end and a nose eiigaging member at its rear end formed with lower nose engaging pads 7 and upper nose engaging pads 8, the nose engaging member in this instance being formed in one piece of metal with the lever 5, and to this end the metal is bent downwardly from the lever and thence upwardly to provide the lower loop 7, the upper end being carried above the lever and being enlarged toform the pad 8.

It will be noted that the lever portion of each nose guard has its flat. faces horizontally arranged. This arrangemcnthas become recognized as the most desirable manner of making a fingei piece nose guard as it reduces the vertical height of the mounting in proximity to the lens attaching devices, but it has its disadvantages when the metal of the lever is cut to provide a hearing, for the. bearing thus formed is not of sufficient length and asa consequence the guard is unsteady on the mounting. In this invention in order to overconie the unsteadiness of a guard formed as above set forth the latter is provided with a pivot pin or bearing 9 projectinglaterally from one of the flat faces of the lever 5 to turn in the bearing 4: in the connecting portion 3, the lever also cooperating with or seating-against the upper face or side of the connecting portion. Of course, the connecting portion has greater thickness than the lever and as a consequence the pivot pin may be given greater length.

The guards are positioned or moved at their rear ends toward each other by springs which in this instancefare carried by the support. Preferably these springs are formed integral with the supports by providing arms on the blanldfrom which the bridging portion is formed, these arms extending in opposite directions to the arms which form the (-(mnccting portions 3 and being located at the ends of the bridging portion. In the completed mounting each blank arm which is to form one of the springs is extended rearwardly, thence outwardly to a point bespring arm .ing the bearing on its guard in cooperatlon hind the proximate lens attaching'device 2 as at 10, thence forwardly and inwardly as at 11 to provide a spring arm, said armpreferably being carried beneath the support so as to'lie on the opposite side thereof from the guard lever which it positions. This may also be utilized for retain- With one of the bearings 4 on the support and to this end it carries a hook member 12 at.its forward end extending upwardly and over the guard lever 5 in front of the pivot of the latter.

It is apparent that the spring arms 11 act on thenguards in such a manner as to swing their nese engaging members toward each other, said'members being separated by moving theforward ends of the levers together.

In order to remove the guards for the re pair of the latter, or for fittlng the mounting,

'to a wearer, it is only necessary to displace the hooked ends of the spring from above the levers 5 when the latter may be removed.

An eye-glass mounting constructed in accordance with this invention'is simple in operation and inexpensive to manufacture. Owing to the form of the bearings greater steadiness in the mounting is obtained without increasing the size of the latter. The springs have a maximum length and strength and are so located that they are invisible from the front, except for small por tions thereof. These springs also serve for retaining the guards on the mounting and when the guards are removed the springs remain with the mounting so that there is no liability of misplacing them. The mounting as a whole has no detachable fastening devices, except the lens screwswhich are necessary in all practicable mountings.

I claim. as my invention:

1. The combination with a' support for the lenses, of a nose guard carrying a pivot pin turning in the support and detachable from the latter with the guard, and a spring for positioning the guard secured to one of said parts and detachably interlocked With the otherto hold the guard on the support.

2. The combination" with a support for the lenses having a vertical bearing, of a nose guard embodying a lever mounted to swing on one sideof the support substan tiallyin a horizontal plane and having permanently secured thereto a vertically arranged pivot pin extending into the bearing 7 of the support and detachable from the lattor with the guard, and a spring for positioning the guard carried by the support and detachably interlocked to the guard to retain the pivot pin in the bearing of the support.
