To all whom it may concern:

Be it known that I,- EDWARD F. Mnssinn, a citizen of the United States., residing at New York, in the county of the Bronx and State of New York, have invented new and useful Improvements in Eyeglasses, of which the following is a specification.

This invention relates to a method o-f mounting the lenses ofan eyeglass or spec.- tacle.

The invention is designed to avoid.drill ing holes through the lens and consequent breakage of the lens.

Heretofore it has been impossible to secure the lens to the `mounting without the aid of a screw extending through a hole in the glass, and enga-ging the strap mountings of the lens. Other methods of mounting the lens have been; by cementing the lens in a box adapted to hold cement. Both these methods are objectionable inasmuch as by the first method the lens is provided with-a screw which projects through a hole in the glass7 and the expansion and contraction caused by sudden changes in temperature will shift the screw thereby breaking the y glass.

The invention obviates the use of a spe.- cial shaped lens for fitting it inv a box filled with cement, whereby the lens is held on the mountin The present invention consists in providing the lens with a series of shallow sockets or indentations for engagement with a series of studs carried by two clamping members which constitute the mounting for the lens. One of the members is equipped with a screw by means of which in connection with a nut, both members are securely clamped to the lens. A fastening of this kind is easily adjusted, and the screw being a permanent fixture of one of the-clamping members cannot get' lost. It preventsthe lens from getting loose and wabbling up and down, and the mounting members or straps from getting loose and pushing away from the lens.

The device needs practically no adjusting after it is mounted on the lens, and being strong and durable accidental breaking of the clamping members is avoided.

The novel features of the invention are more fully described in the following speciication and claims and illustrated in the accompanying drawing in which:

Figure l represents a front elevation of al1 eyeglass embodying this invention. Fig. 2 is a similar view on a larger scale of a portion of the eyeglass. Fig. 3 is a horizontal section taken along the line m of the same. Fig. 4 is a vertical section taken along' the line g/ y ofthe same.

In this drawing is shown an eyeglass having lenses a provided with sockets b near the inner edge of the lens. These sockets or recesses are located on the inner and outer faces of the lens, and coact with studs c and d fixed to the respective clamping members or straps e and f. The inner clamp f has its outer and inner wall g turned outwardly to form a boxlike receptacle for mounting the terminals of a nose guard h and a. spring bridge piece i. The inner clamp is also provided with a screw stem j which is preferably countersunk and fixed tothe clamp as shown or it may be headed to set on the outside of the clamping member. The screw passes through eyes formed in the said spring bridge, guard andthe outer clampingmember e. A nut c is threaded on the stem and is adapted for adjusting the two clamping members.A The nut may be angular, or as indicated may have slots locat-ed in the periphery of the nut, so that a tool can be inserted and the nut adjusted'.

It should be said that the upper and lower parts of the box are open to allow the'spring bridge and guard to project therefrom. The outer clamping member e has a lip m eX- tending over the wall g of the box, so as to guide the member and keep it in line with the member f when the two are fitted together.

When the nut is tightened both the clamp- I ingmembers are drawn toward each other andthe studs will engage the sockets in the lens thusv firmly gripping the lens. The sockets may be of any shape and the studs could be in the form of a ball or semi-circle to fit corresponding indentations or countersunk portions of the glass.

Itmay be stated that the clamping members can be employed for all rimless mountings, finger vpiece eyeglasses, rimless spectacles etc.

I claim:

l. In an eyeglass the combination with a lens provided with a series of sockets located at the inner and outer face portions of the lens, a pair of clamping members having studs for engagement with the sockets, a screw fixed to one of the members, a nose guard and a spring bridge mounted on the o mounted on the screw, said clamping members having extended portions to constitute a receptacle for housing the terminals of the nose guard and bridge, means coacting with the screw and the other clamping member for adjusting the clamps. v

3. In an eyeglass the combination with a lens provided with pairs of sockets each pair being located at the inner and outer face ortions of the lens,u a pair of clamping mem ers having studs for engagement with the sockets, a screw fixed to one of the members, a nose guard and a spring bridge mounted on the screw, said clamping members having extensions with closed ends to constitute a receptacle for housing the terminals of the nose gua-rd and bridge, and a nut t0 engage the screw for adjusting the clamps.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
