Description
Sept. 6, 1938. J. w. ASPENLEITER I OPHTHALMIC MOUNTING Filed Dec. 16. 1955 EPH w. ASPENLEITER .INVENTOR Patented Sept. 6, 1938 UNITED STATES T OFFIQE OPHTHALMIC MOUNTING Application December 16, 1935, Serial No. 54,560
8 Claims.
The present invention relates to ophthalmic mountings and more particularly to means for by inserting a leaf spring between the shoe and the edge of the lens but this spring introduced other difiiculties. Unless the mounting were set with great accuracy, one side of the spring would be distorted more than the other and this distorted side would tend to turn the shoe and straps about the screw as an axis. In one direction, this turning would tend to loosen the screw while in the other direction it would tend to tighten the screw and strain the lens. Furthermore any slight force exerted on these connections, such asmoving the temples when placing the spectacles in a case, would cause a slight movement of the connection about the screw as an axis and would tend either to loosen or to tighten the screw. Either of these latter results is both undesirable and annoying.
One of the objects of the present invention is to provide a lens connection for an ophthalmic mounting, which connection is simple and easy to attach, yet rugged and durable in operation. Another object is to provide a lens connection having a spring shoe and which will not pivot about the attaching screw. A further object is to provide an ophthalmic mounting having a rigid shoe rockably secured to the lens straps. These and other objects and advantages reside in certain novel features of construction, arrangement and combination of parts as will hereinafter be more fully set forth and pointed out in the appended claims.
Referring to the drawing:
Fig. 1 is an elevation of one embodiment of my invention.
Fig. 2 is a horizontal section thereof.
Fig. 3 is an elevation of another embodiment of my invention.
Fig. 4 is a horizontal section of the embodiment shown in Fig. 3.
In the embodiment shown in Figs. 1 and 2, I0 indicates a lens to which an ophthalmic mounting I I is secured. The mounting II has the usual shoe I2 and a leaf spring I3 is secured to the shoe I2 by suitable means, not shown, so that the spring I3 will contact the edge of the lens III.
A pivot rod or rivet I4 extends through the shoe I2 and two straps I5 and Iii are pivotally mounted on the rod I I on opposite sides of the shoe I2 for engaging the opposite surfaces of the lens Ill as shown in Fig. 2. The outer ends of the straps I5 and It are perforated at II and I 8 respectively and a screw I9 is threaded into these perforations and extends through a hole 26 in the lens It thus securing the lens to the mounting II,
The shoe I2 and mounting I I are pivotally con-. nected to the straps I5 and I 6 by the rod I l and any unequal stress in the spring I3 is taken up by pivotal movement about the rod It as an axis instead of pivotal movement about the attaching screw I9 as an axis; Strains placed on the mounting II are likewise taken up by pivotal movement about the rod M and thus the tendency to turn the screw I9 is eliminated. The shoe I2 and mounting II are cut away adjacent the rod I4 and are provided with shoulders II which cooperate with the straps I5 and I6 to limit the pivotal movement about the rod I I.
In the embodiment shown in Figs. 3 and 4, the ophthalmic mounting 22 has two spaced arms I23 and 24 rigidly connected to the shoe 25. The leaf spring 26 which engages the edge of the lens III, is secured to the shoe 25 by a rivet 2'6. The lens straps 28 and 29 are secured together in the form of a U-shaped member which extends over the shoe 25 between the arms 23 and 24 and engages the opposite surfaces of the lens Ill. The straps 28 and 29 are perforated at 30 and SI respectively, and a screw I9, threaded into these perforations, extends through a hole 263 in the lens I0 and secures the straps I28 and 29 and the mounting 22 to the lens It. It is apparent that the mounting 22 and shoe 25 are thus free to rock about the U-shaped end of the straps 28 and 29.
From the foregoing it will be apparent that I am able to attain the objects of my invention and provide a lens connection for an ophthalmic mounting which connection is simple and easy to attach yet durable and efficient in use. While I have illustrated my lens connection as applied to end pieces only, obviously it could be as well applied to any ophthalmic mounting for rimless spectacles such as a bridge, stud or the like. Also the means for securing the lens straps to the lens is not limited to a screw but any of the socalled screwless connections may be used. Various other modifications can, of course, be made without departing from the spirit of my invention or the scope of the appended claims.
I claim:
1. In a device of the character described, two straps adapted to be rigidly secured respectively on opposite sides of a lens, means connecting said straps beyond the edge of said lens, a shoe rockably secured on said means, a resilient member between said shoe and the edge of said lens, and an ophthalmic mounting rigid with said shoe.
2. In a device of the character described, an ophthalmic mounting, a shoe having an aperture therethrough secured to said mounting, a spring secured to said shoe for engaging the edge of a lens, two spaced straps positioned, respectively, on opposite sides of said shoe and adapted to engage the opposite surfaces of a lens, and a member joining said straps and extending through the aperture in said shoe for pivotally connecting said shoe and said straps.
3. In a device of the character described, an ophthalmic mounting, a shoe rigid with said mounting, resilient means secured to said shoe and adapted to engage the edge of a lens, and two straps pivotally connected to said shoe on opposite sides thereof for securing a lens therebetween in engagement with said resilient means.
4.

5. In a device of the character described, an ophthalmic mounting, a shoe rigidly fixed thereto, a resilient member secured to said shoe and adapted toengage the edge of a lens, a rod extending through said shoe, two straps pivotally mounted on said rod, one on each side of said shoe for engagement with the two surfaces of said lens and means for limiting the relative pivotal movement between said straps and said shoe.
6. In a device of the character described, an ophthalmic mounting, a shoe having an opening therethrough secured to said mounting, a spring secured to said shoe and adapted to engage the edge of a lens, and a U-shaped strap member adapted to extend loosely through said opening and engage the opposite side of a lens.
'7. In a device of the character described, two straps adapted to be rigidly secured on opposite sides of a lens, a shoe rockably mounted on and between said straps beyond the edge of said lens, a resilient member between the shoe and the edge of the lens and an ophthalmic mounting rigidly connected to said shoe.
8. A device of the character described comprising two straps rigidly secured on the opposite surfaces of a lens, means connecting said straps beyond the edge of said lens, a shoe connected to said straps for rocking movement about said means, a resilient member between said shoe and the edge of said lens and an ophthalmic mounting rigidly secured to said shoe.
