EYEGLASS mum-me Filed April 15, 1937 INVENTOR.

ATTORNEY.

Patented June 20, 1939 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates generally to eye glasses, more particularly to the manner of mounting the lens in the bow and nose piece of rimless lenses.

and unique mounting for eye glass lenses of a character to avoid the piercing of the lens as is commonly the practice resulting in a weak connection between the bow or nose piece and the lens.

Further, the object of the invention is to provide a bracket for the nose piece and similar bracket for the bows permitting a ready assembly or disassembly of the bracket or mounting from the lens and to provide a construction in which, when the parts are assembled, the lens is firmly clamped by the brackets.

It is further a feature and object of the invention to provide a lens mounting that avoids use of springs and delicate parts that readily'get out of order or become inefiicient and further, to provide a simple and inexpensive mounting for securing the bow and nose piece to a lens.

These and other objects and various novel features of the invention are hereinafter more fully described and claimed, and the preferred form of construction of a mounting for the bows and nose piece of rimless spectacles is shown in the accompanying drawing in which- Fig. 1 is an elevation on an enlarged scale showing a lens and my improved bracket or mounting secured to opposite sides of the lens.

Fig. 2 is a plan, partly in section taken on line 2-2 of Fi 1.

Fig. 3 is a plan view of the mounting to which the nose piece is fastened.

Fig. 4 is an elevation partly in section showing a structural detail of the nose piece bracket.

Fig. 5 is a plan view of the mounting to which 40 the bows are attached.

The preferred form of construction of my improved lens mountings is shown in the accompanying drawing in which a lens of the rimless type is indicated at l. The lens shown is octag onal in form although the mounting is adapted for use with other forms. One of the purposes to be attained by my improved mounting is to avoid the piercing of the lens in the securing of the bracket for the nose piece and for the bow to the lens. In my improved mounting, the bow bracket is indicated at 2 and the nose piece bracket at 3 and these are quite similar in structure as is hereinafter described.

The bow mounting consists of two pivoted parts 4 and 5, the part 4 having an arm 6 and the The object of the invention is to provide a new part 5 having a similar arm I and these are pivoted on a pin 8 and thus form levers. The lever 4 has an aperture 9 at the extremity opposite the end 6 while the lever 5 has a threaded aperture ID at the end of the lever opposite the end The lever 5 has a downwardly extending glass engaging lug II and the upper lever 6 of the pair has an upwardly extending lug I2 which, as shown in Fig. 1, engages the lens edge.

Each of the lever ends 6 and is preferably spatulate in form as indicated at l3 in Fig. 1 and the spatulate end of the lever B has a small projecting knob I4 which engages in a recess provided therefor on the inner face of the lens. About this projecting knob is a compressible washer I5 preferably formed of cork and the. arm 1 has also a washer 5, these two washers therefore engage the glass under pressure when the parts are assembled.

In placing the bracket 2 on the lens, it is first in the open position as shown in Fig. 5 and is placed over the glass. The ends of the parts 4 and 5 containing the apertures 9 and ID are reduced in thickness and provide a space into which the eyed end ll of the bow l8 may be positioned. The bracket elements 6 and l are broughttogether to the position shown in Fig. 2 which causes the aperture 9 to align with the threaded aperture II]. A screw I9 is then introduced through the aperture 9 and eye of the bow and threaded in the aperture Ill. The screw l9 thus holds the lever ends 6 and in position clamping the glass and with the knob M in the recess of the glass which will prevent the bracket from slipping off from the lens. This securely holds the lens and provides a strong mounting of the lens and bracket due to the fact that the lens itself is not apertured. It is also to be noted that the lugs II and I2 are brought to the desired relative alignment by the swinging of the levers on the pin 8 to align the apertures 9 and I0. Thus all parts are firmly held in their proper relation simply by a single screw and the mounting is held from turning on the knob as a pivot by means of the lugs II and I2.

The mounting for the nose piece 20 is of similar construction, as shown in the enlarged View in Figs. 3 and 4, and consists of the two levers 2| and 22 each respectively carrying lens engaging lugs 23 and 24 and the end of the lever 2| is provided with a projecting knob 25 for engagement in a recess in the inner face of the glass in the construction here shown. These two levers are pivotally mounted upon a pin 26 and the lever 2| has an aperture 21 shown in full lines in Fig. 3

and the lever 22 has an aperture 28, shown by dotted lines, which is brought to alignment when the levers are brought to clamping position on the lens as shown in Fig. 2. A screw 29 is introduced from the under side of the levers 2| and 22 through the apertures therein and has a threaded end 30 of somewhat less diameter than the body of the screw which engages in the end 3| of the nose piece 32. This shouldered screw prevents the binding of the two levers together and the screw IQ for the lens mounting is also preferably of the shouldered type for the same reason.

The nose piece of the spectacles usually carries,

the nose clips 33 which may be attached to the nose piece by an arm at. In the assembly of the nose piece with the bracket 3, the two lever parts of the bracket are clamped on the glass manually to bring the aperture 2': in alignment with the aperture 28 and the screw 29 introduced therethrough and threaded in the terminal end 3| of the nose piece.

Thus the functional relationship of the nose piece and mounting is the same as that of the bow and its mounting. The simple removing of the screw permits disengagement of the clamp from the lens or introduction of the screw in a manner hereinbefore stated clamping the respective nose piece or how mounting on the lens and securely holds the same in position.

I have only shown one part of a nose piece and a single nose clip but the other lens of the pair and the mountingstherefor are a duplicate of those shown in Fig. 1.

I have described the device as particularly applied to spectacles wherein bows are required to be mounted on the lens as well as the nose piece but it is to be observed that the invention is also involved in the use of the nose piece only as in the case of eye glasses.

From the foregoing description, it is believed evident that my improved lens mounting is of simple and unique construction; inexpensive in character, and is readily mounted or dismounted from 'the lens and avoids the piercing of the lens and thus provides a stronger mounting and one less liable to crack the lens than is the case where the lens requires to be pierced and thus weakened.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is l. A mounting for the lenses of eye glasses comprising the association with a lens having a recess in one face adjacent the edge thereof, a pair of pivoted levers approximately equal in length, one of the levers on one side of the pivot point having a projection for fitting the recess and both the levers on the opposite side of the pivot point having apertures brought to registration when the first named ends of the levers are in clamping engagement with the lens, one of the said apertures being threaded and the apertured ends being spaced apart, a bow having an eye positioned between the lever ends in alignment with the apertures, and a screw stud extending through the aperture of one lever and the eye piece of the .bow to threaded engagement with the aperture of the other lever thereby maintaining the levers in clamping engagement with the lens and pivotally securing the bow in place.

2. A mounting for securing the nose piece to the lens of eye glasses comprising the association with a lens having a recess in one face thereof adjacent the edge, of a pair of pivoted levers approximately equal in length, one of the levers on one side of the pivot point having a projection for fitting the recess and both the levers on the opposite side of the pivot point having apertures brought to registration when the first named ends are in clamping engagement with the lens, the nose piece having an end portion provided with a threaded aperture, and a screw extending through the apertures of the levers to threaded engagement with the threaded end of the nose piece thereby securing the nose piece to the mounting and maintaining the levers in clamping relation with the glass.

3. A mounting for the lenses of eyeglasses comprising the association with a lens having a recess in the face adjacent the edge thereof, of a pair of levers pivoted to turn on an axis parallel with the plane of the lens at the edge, at least one of the levers on one side of the pivot point having a projection fitting the recess in the lens and the corresponding end. of the other lever engaging the opposite face of the glass, the ends of the levers on the opposite side of the pivot point having flat surfaces provided with apertures, said surfaces being in a plane at a right angle to the plane of the lens at the edge, the apertures in the said ends being brought to registration when the first named ends of the levers are moved to clamping engagement with the lens, and a headed screw member inserted in the aligned apertures to maintain said clamping engagement, said screw member cooperating with means on an ophthalmic element of the eyeglass to secure said element to said mounting.
