EY 8 RIM.
APPLICATIO D MAR. 6' I920.

UNITED STATES PATENT OFFICE.
JOHN F. HOEFT, OF GRAND ISLAND, NEBRASKA.
EYEGLASS-BIIM- Specification of Letters Patent Patented Oct. 19, 1920.
Application filed. March 6, 1920. Serial No. 363,645.
. having a metallic tongue disposed within a cut out portion of the lens and through which passes the securing screw for hold ing the lens upon the nose piece or mounting, the advantage being that danger of breaking the lens by securing it too tightly to the mounting, is avoided.
An important object is the provision of a rim of this character which is disposed within and secured to the frame which may be of the horn style in popular use at the present time, this horn frame being secured to the metal rim surrounding the lens whereby turning of the lens with respect to the frame will be prevented.
An additional object is the provision of a rim of this character which will be simple and inexpensive in manufacture, highly eflicient in use, durable in service, and a general improvement in the vart.
With the above and other objects and advantages in view, the invention consists in the details of construction to behereinafter more fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is an elevation of an eye glass constructed in accordance with my invention,
Fig. 2 is a similar View with the ornamental or colored frame removed,
Fig. 3 is an edge elevation with the ornamental frame in position,
Fig. 4 is a detail sectional view taken through the tongue, and
Fig. 5 is a detail cross sectional view through one edge of the lens, the rim and the frame.
Referring more particularly to the drawings, the letter A designates the ordinary mounting of an eye glass including at each side the fork B through which passes a screw C for holding the lenses to the mounting. In ordinary practice the lens is provided with a. hole registering with the .hole in the fork B through which passes the securing screw. quently tightening of this screw to an excessive extent results in breaking the lens. It is with these objections in view that the present invention has been designed. I
In carrying out my invention I provide the lens D with a substantially rectangular cut out portion'lO andvprovide a rim 11, formed of metal, surrounding the lens at its edge. Formed upon this rim is a tongue 12 which is disposed within and which fills the cut out portion 10 and the thickness of this tongue is the same as that of the lens at its edge. The tongue 12 is at one end of the rim and the other end of the rim is disposed within a bifurcation 13 formed in the first mentioned end of the rim at the tongue. The two ends of the rim are secured together by a very small pin 14 which passes through the two ends, as clearly shown. The tongue 12 has formed therein a hole 15 for the passage of the securing screw C which connects the lens with the mounting.
Surrounding the rim 11 is a frame 16 of tortoise shell or other material used as a substitute therefor, and this frame is formed as a circular band channeled for the reception of the rim 11 and has its ends terminating at the ends of the arcuate lens engaging members E of the mounting. The terminals of the frame 16 are secured to the rim 11 by means of small pins 17 which extend through the frame and into the rim.
It will be seen that when an eye glass is constructed'and assembled as above described, there will be no strain upon the lenses, regardless of how tightly the screw C is turned in and breakage of the lenses vill therefore be prevented as far as this cause is concerned. Another feature of advantage is that this construction permits the use of the popular colored frame of tortoise shell or similar appearing material and this frame is moreover secured to the metallic rim surrounding the lens and is not secured to the mounting at all. This construction is far preferable to the old and well known style in which the lenses were mounted only in circular frame of horn or other material as in the old style the lenses frequently rotated and thus became out of focus. In the present construction as described, any rotary movement of the lens is of course positively prevented.
lNhile I have shown and described the preferred embodiment of my invention, it
It is well known that he is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim:
1. In combination with an eye glass mounting'and lens therefor, a rim surrounding the lens, the mounting including a forked arm secured to the lens and further including an arcuate bearing portion engaging against the rim surrounding the lens, a frame surrounding the rim and having its ends terminating at the ends of said arcuate portion of the mounting and secured to the rim.
2. In combination with an eye glass mounting and lens therefor, the mounting including a forked arm having a hole through which passes 'a securing screw, the lens having at one edge a cutaway portion;
metal rim surrounding the lens and having formed thereon a tongue disposed within and filling said cut away portion and said tongue having a hole for the passage of said securing screw, said tongue being ing'the lens andhaving formed thereon a tongue disposed within and filling said cut away portion and said-tongue having a hole for the passage of said. securing screw, and
airamesurrounding said rim and having its end portions terminating at the ends of the lens engaging arcuate portions of the mounting and said ends of the frame being secured to said rim.
In testimony whereof I afiiX my si nature.
- JOHN 1F. noiarr.
