MOUNTING FOR EYEGLASSES.
Specification of Letters Patent.
Patented Jan. 21, 1908.
Application filed September 12, 1906. Serial No. 334,296.
T 0 all whom it may concern:
Be it knownthat I, GEORGE BAUsoH, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Mountings for E ye- 1 glasses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to certain improvements in mountings for eye-glasses, and refers-more particularly to the structure of the spring-bow and manner of connecting it to the posts to which the lenses are attached.
The essential objects are, first to increase the general flexibility and resiliency of the "mounting, and particularly the bow-spring so as to afford greater scope of adjustment of the lenses to conform to different conditions of the eyes without permanently bending or reconstructing the mounting. In other words, I have sought to introduce a longer, and consequently more resilient leverage in the active portions of the bowspring, and at the same time to enable the lenses to be adjusted toward and from the eyes relatively to the bow of the spring without permanently bending any portion of the bow-spring from its original shape.
A further object is to adjustably clamp the ends of the bow-spring to the posts between the box and lens clamps so as to afford as long a leverage as possible in the action of the ends of the bow-spring.
Other objects and uses will appear in the following description.
In the drawingsFigures 1, 2, and 3 are respectively enlarged top-plan and front and rear elevations of my-irnproved mounting showing portions of the lenses or eye-glasses attached thereto. Fig. 4 is a sectional view taken on line 44, Fig. 2, showing the relative arrangement of one end of the bowspring and post, and means for adjusting and clamping the spring to said post.
.As shown in the drawings, this mounting consists essentially of a one-piece bowspring 1 of comparatively light spring metal, having its central portion arched upwardly and forwardly tofit the nose, and its opposite extremities deflected forwardly and adjustably secured to the central portions of suitable posts 2. Each of these posts is provided at one end with a lens clamp 3, and at its opposite or inner end with a box 4, for receiving a shank of a noseguard 6 Each of the lens clamps consists of a pair of ears adapted to clasp opposite faces of the,
lens, as a, said lens and ears being formed'of suitable apertures for receiving a clamping bolt or screw 7 whereby the lens is rigidly attached to the post. These clamps are provided. with the usual rim fingers -8- for engaging the periphery of the lens and bracing it against rocking movement upon its fastening screw 7.
Each of the posts -2-- projects radially from the lens and is provided with an aperture 9- located between the clamp 3 and box 4 for receiving one end of the bow-spring 1, said aperture and the adjacent end of the bow-spring being disposed at substantially right angles to the plane of the lens to permit said lens to be adjusted toward and away from the eye and relatively to the nose-pieces 6, or in other words,
the bow-spring is ad usted in the apertures 9 to different planes relatively to the planes of the lenses so as to bring the eye glasses closer to or further away from the eyes when the bow is resting upon the nose.
Each of the boxes '4 is channeled vertically to receive the shank 5 of the nosepiece, said shank and post being provided with apertures for receiving a clamping screw 10,the aperture in the post being threaded to engage said screw, which also engages the adjacent end of the bow-spring to lock the post and bow-spring in their adjusted positions relatively to each other.
In order to increase the leverage and re siliency of the spring, the portions of said spring oining the central arch to the offsets which enter the posts, are bent in the form of loops '11 which introduces greater flexibility and enables the lenses to be sprung apart, or forwardly and rearwardly, as well as vertically, with greater freedom than would be possible if the ends of the arch of the bow entered directly into the posts.
The essential feature, however, of my invention is first, attaching of the ends of the bow-spring to the intermediate portions of the posts between the lens clamps and their boxes; second, the adjustability of the posts upon the ends of the bow-spring, or rather the adjacent ends of the bow-spring in the posts, and third, extending the drill-hole for the screw lengthwise into the post a sufficient distance so that its end engages the portion of the bow-spring inserted therein, whereby the same screw which fastens the nose-piece in the box is utilized to lock the post and. the end of the bow-spring together.
What I claim is:
1. In a mounting for eye-glasses, a pair of posts each having a lens clamp at one end and a box at its opposite end, nose-pieces mounted in the boxes and a bow-spring having its ends secured to the posts between the boxes and lenses for increasing the leverage and resiliency between the arch of thebow and its point of fastening to the lens posts.
2. In a mounting for eye-glasses, a pair of posts each having a lens clamped at one end and a channeled member on the opposite end, nose-pieces secured to said channels and a bow-springhaving its ends extended some distance beyond the nose-pieces and attached to said posts between their ends.
3. In a mounting for eye-glasses, a pair of lens posts having boxes on their ends and transverse apertures between boxes and lenses, in combination with a bow -spring having its ends secured in said apertures and nose guards secured in said boxes.
4. In a mounting for eye-glasses, a pair of lens posts having boxes on their ends and transverse apertures between boxes and lens, in combination with a bow-spring having its ends adjustably secured in said apertures and nose guards secured in said boxes.
5. In a mounting for eye glasses, a pair of lens posts attached at their outer ends to their respective lenses, noseguards secured to the inner ends of said lens posts, and a bow spring having its ends secured to the lens posts between the nose guards and points of attachment of the lens posts with the lenses.
In witness whereof I have hereunto set my hand this 1st day of September 1906.
