EYEGLASS CONSTRUCTION Filed Feb. 12, 1929 a INVENTOR ATTORNEY Patented Feb. 16, 1932 UNITED STATES PATENT OFFICE GEORGE E. NERNEY, OI ATTLEBORO, MASSACHUSETTS, ASSIGNOR TO BAY STATE OPTICAL COMPANY, A CORPORATION OF MAINE EYEGLASS CONSTRUCTION Application filed Iebruary 12, 1929. Serial No. 339,332.
This invention relates to eyeglass construction and more particularly to the construc tion of eyeglasses in which nose-engaging members are mounted upon swinging levers.
One of the objects thereof is to provide a practical construction of the above type of a simple and durable nature. Another object is to provide a construction of the above 15 pe characterized by efficient and dependable action. Another object is to provide a construction of the above type which shall be adapted to meet the severe conditions of practical use and maintain its original eiiiciency. Other objects will be in part obvione and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings, in which is shown one of various possible embodiments of this invention,
Figure 1 is a front elevation on an enlarged scale partially in section along the line 1-1 of ig. 2;
Fig. 2 is a plan partially broken away and partially taken in section along the line 2-2 of Fig. 1; and
Fig. 3 is a detail elevation of a lever partially cut away in order to show the construction more clearly.
Similar reference characters refer to similar parts throughout the several views of the drawings.
Referring now to these drawings in detail, there is shown a bridge interposed between a pair of lenses 11. As the construction at each side of the middle of the eyeglasses is substantially identical with that on the other side, the construction of one side only will be described in detail.
Lens 11 is here shown as mounted within a lens clamp comprising the Wings 12 upon a strap or circumferentially extending part 13, the lens being closely embraced by the Wings and resting against the strap and held in position by a screw 14 passing through the lens as well as the adjacent wings. There is nothing novel in this form of lens sup ort considered in and of itself, and it may ere' be noted that the term lens-supporting means is used throughout in a broad sense to comprehend any device capable of supporting the lens, whether of the above nature or in the form of a rim within which the lens is fitted. It may also be noted here that the term eyeglasses is used in its broad sense to include the spectacle form of ophthalmic mounting as well as the form which is supported only by the nose.
Referring to Fig. 1 of the drawings, it is to be noted that the bridge 10 extends directly into thelens support, thus bringing the lens nearer to the nose and permitting lenses of a large size to be used without undue increase of the pupillary distance. The end portion of the bridge is formedas shown at 15 into a substantially circular abutment provided with an annular bearing surface 16 which is preferably beveled in an upward and inward direction.
Formed upon the lens support beneath the part 15 and substantially registering therewith is a lug 17 which is provided with a bearing surface 18 also preferably beveled in an upward and inward direction, this beveling being exaggerated in degree as shown in the drawing A swinging lever, or so-called fingerpiece 19 is provided at its rear end with a noseengaging member or nose-pad 20, preferably secured thereto as by the curved part 21 so as to facilitate adjustment. The forward end of the lever is provided with a finger-grip 22 by which it may readily be manipulated in the usual way when the glasses are placed in position or removed from the nose.
The lever 19 is provided with a central barrel 23 adapted to fit snugly between the parts 15 and 17 and provided with surfaces shaped to coact with the bearing surfaces 16 and 18 and thus, when it is snapped into position, form a pivotal connection with the frame. Prior to the assembly of this part it has inserted therein a coil spring 24, the lower end of which is anchored within a slot 25 cut at the bottom of the barrel. The upper end passes through a recess 26 and bears against the rear side of the bridge as shown at 27, thereby tending to swing the noseengaging member 20 toward the nose to a degree limited by any suitable stop device.
It will thus be seen that the spring as well as the bearing surfaces are shielded from the accumulation of dirt and the corrosive action of perspiration and, while given ample freedom to perform their functions, are nevertheless self-contained and tend to maintain themselves in efficient condition for an indefinite time under the most severe conditions of use.
' Passing upwardly through the lug 17 is a screw 28 which is seated at its upper end 29 "in a threaded recess at the bottom of the end portion 15 of the bridge. This screw serves to adjust to some extent the tightness of the bearing surfaces of the lever, and furthermore adds to the security of the pivotal connection as well as providing a positive means of holding the spring in alignment. Although it thus to some extent acts as a pivot screw, it is to be noted that there is notendency in the use of the device to loosen or unscrew it from its original position.
. The eyeglasses as above described are used in the ordinary manner common to so-called linger-piece mountings, and the parts are readily assembled or disassembled if for any reason renewal or repairs are required.
It will thus be seen that there is provided a device in which the several objects of this invention are accomplished.
As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbeforeset forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
