Description

LENS RIM Filed Feb. 27, 1941 INVENTOR.
ATTORNEYS.
Patented Mar. 17, 1942 ETED LENS RIB 1 Frank W. Lindblom, Auburn, R. I., assignor to Welsh Manufacturing Company, a corporation of Rhode Island 1 Claim.
This invention relates to an ophthalmic mounting, particularly the rim thereof.
Heretofore in the use of lens rims for an inexpensive securing of the rim about the lens, it has been usual to provide a box on one end of the rim to slide along a bridge connection to close the rim on the lens. Lenses differ in size to such an extent that it is dimcult to have a meeting of the ends at the joint of the rim, and unless these portions abut, they are unsightly.
One of the objects of this invention is to provide an arrangement whereby some variation in the size of the lens rim may be had and yet an unsightly joint will be eliminated in a very inexpensive manner.
With this and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.
In the accompanying drawing:
Fig. l is a face view of a frame with lenses mounted therein;
Fig. 2 is a central section through the rim and lens illustrating the joint in secured position;
Fig. 3 is a section on line 3-3 of Fig. 2;
Figs. 4 and 5 are oppositely arranged perspective views of the rim prior to embracing the lens; and
Fig. 6 is a perspective view similar to Fig. 5, but showing a modified arrangement of the rim.
In carrying out this invention, I have found a simple manner of connecting the rim end portions about the lens by providing an opening on one end of the rim and a tongue on the other end to extend through this opening to be bent to hold the rim in desired position.
With reference to the drawing, lfl designates the body portion of a lens rim which is grooved as at H to receive the beveled edge l2 of the lens [3. One end of this channel-shaped rim is fashioned to provide a tongue M by cutting down the end portion, while the other end is provided with a shoe l5 which is of channel construction of a size to receive the end l6 of the body l0 and is secured thereto in any suitable manner such, for instance, as by welding or soldering. This shoe is provided with an opening H of a size to receive the tongue [6, the arrangement being such that the end portion it of the body may also be received within the channel of shoe I5.
In this manner the channel will cover the joint formed between the ends of the shoe, and by the provision of a tongue sufiiciently long, considerable variety of different sized lenses may be accommodated by merely passing the tongue through the opening H and bending the same over as at 19 (see Fig. 2).
The two lens rims in secured position are shown at 29 in Fig. 1 and are connected together by a bridge 2| held in boxes at its ends 22 in any suitable manner, which boxes are also secured to the rims.
In the showing in Fig. 6, I have illustrated that the rim may be ornamented as at 24 and have provided an opening 25 in the end of the body portion of the rim itself rather than in a separate shoe attached to the rim. The reduction of the tongue [4 is such that it may pass into the channel of the rim and extend through the opening 25 and be bent over as at [9.
In all cases, the tongue affords a complete closingof the joint of the lens rim; and in the use of the shoe, the side walls as well serve to close the joint between the ends of the rim in various positions of expansion.
I claim:
In an ophthalmic mounting, a lens rim having a body portion to encircle the lens, a shoe having an opening therein receiving the end of the body and attached thereto and extending from said body portion and with the opening located in the extending part of said shoe, the other end of said body also being received in the extending part of said shoe and provided with a bendable tongue to extend through said opening and be bent to lock the ends of the rim in said shoe.
