Description

NITED STATES PATENT ()FFIGE.
WILLIAM H. PECKHAM, OF BIG SPRINGS, KANSAS.
IMPRPVEMENT IN EVE-GLASSES.
Specification forming part of Letters Patent No. 165,251, dated July 6, 1875; application filed June 9, 1875.
To all whom it may concern Be it known that I, WILLIAM H. PEGKHAM, of Big Springs, in the county of Douglas and State of Kansas, have invented a new and useful Improvement in Spring Eye-Glasses; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings forming a part of this specification.
The nature of myinvention consists in having a 'hollow slot through the post through which the nose-sprin g passes and rests against a shoulder formed by the spring. After passin g the nose-spring through the slot, a small spring which forms a part of the nose spring, catches under or on one side of the slot in the post thereby preventing the spring from 'falling out or getting loose in its place.
In the accompanying drawings, Figure 1 is an elevation of a pair of eye-glasses constructed according to my improvements. Fig. 2 is a detail of a part of the nose-spring, showing the small spring which fastens it to the post of the glass-bow or frame. Fig. 3 is a detail of a part of the frame. A A is the frame; B B B, the nosespring; c c, the small springs which hold the nose-spring in its place; (Z d, the posts of the frame containing slots through which the nose-spring passes. E E is a lug, which forms the base in which the ends of the nose-spring B rest.
This mode of fastening is so' simple in its construction that, should the nose spring break, it can be readily removed by any pen son, even the most inexperienced, by merely pushing in the small spring in the nose-spring underneath the post attached to the rim of the eyeglass and drawing out the nose-spring from the slot through which it passes. The lug E, forming the base upon which the nosespring rests, has a hole or slot in the same which receives the end of the nose-spring, so as to give stability and strength to the entire length and breadth of the said spring. The surface of the bearing-spring, or that part which spring c, in combination with slotted post d and lug E, substantially as shown and described, and for the purpose specified.
WILLIAM H. PEGKHAM.
