J. R. LAWRENCE.

WATCH MAKERS EYEGLASS. No. 350,005. Patented Sept. 28, 1886.

Jan/B170? WW UNITE is TATES JOHN R. LAWRENCE, OF HIGHLAND PARK, ILLINOIS, ASSIGNOR TO MILTON H. BAKER AND EVA M. LAWRENCE, BOTH OF SAME PLACE.

WATCH-MAKERS EYEGLASS.

SPECIFICATION forming part of Letters Patent No. 350.005, dated September 28, 1886.

Application filed January 26, 1886. Serial No. 189,781.

T at whom it may concern:

Be it known that I, J OHN R. LAWRENCE, a citizen of the United States, residing at High land Park, in the county of Lake and State of Illinois, have invented a certain new and useful Improvement in \Vatch-Makers Eyeglasses, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, formr: ing a part of this specification.

My invention relates to watch-makers eyeglasses; and it consists in the frame or support by which the glass is held in place in front of the eye by the muscular contraction of the eyelids. Heretofore the lens has been set in one end of a cylindrical frame, the other end having a flaring edge for retaining the same Within the ocular orbit. Rubber and bone have been commonly used in mak- 2o ing such frames. These frames are necessarily rigid, and they cannot be folded or in any way reduced in size, so as to bring the eyeglass within small compass.

In the use of cylindrical frames of the character described considerable heat is generated near the eye, which is very objectionable, while the weight of the cylinder is considerable.

By the use of my invention the frame is 0 made adjustable, so that the eyeglass may be folded into a small space, light and air are admitted, and the weight greatly decreased, while at the same time the cost of manufacture is greatly lessened.

My invention will be readily understood by reference to the accompanying drawings, in which Figure 1 shows my watch-makers eyeglass held in place by the eyebrows. Fig. 2 is a perspective view thereof. Fig. 3 shows 0 the wings or loops spread out horizontally. Fig. 4 is a detailed view of one of the ears which carry the loops. Fig. 5 is a detailed view of that part of one of the loops which fits into one of the ears. 1

Like parts are indicated by similar letters of reference in the different figures.

The glass a may be of the form and kind required. This glass is set in a ring, I), as

(No model.)

shown. The ring is provided with ears 0 d one on each side. The loops or wings ef are of wire, and are preferably left open at g, as shown in Fig. 5, so that they may be readily sprung apart and slipped into the socket h, provided in the ears. The grooves t are so formed that the loops will be braced apart 5 when held in position at the eye. The groove It tends to hold the loops in their horizontal position when extended, as shown in Fig. 3.

It is evident that my glass as thus described is adapted to the use of engravers, 6o diamond-merchants, and cloth-merchants, as well as watch-makers. I have sometimes dispensed with the ring I) and riveted the ears directly to the glass. It is evident, also, that the form of the wings, as well as that of the 6 ears, may be varied in different ways without departing from my invention.

Having thus described my inventioml claim as new and desire to secure by Letters Patent- 1. The ring containing the lens and the ears attached thereto and the wire loops or wings fitted to the sockets in the ears, said ears being provided with grooves whereby the loops or wings are braced apart when held at the eye, and when extended are held in their horizontal position, substantially as and or the purpose specified.

2. The combination, with the glass (1, of the wings or loops 6 j on opposite sides thereof, and ears for attaching the said wings or loops to the glass, said ears being provided with grooves for bracing said wings and holding the same when extended horizontally, substantially as and for the purpose specified.

3. The combination, with the eyepiece, of the folding wire wings e f, pivoted on opposite sides thereof, said wings flaring outwardly, whereby the glass may be supported by the muscular contraction of the eyebrows, substantially as and forthe purpose specified.

In witness whereof I hereunto subscribe my name this 20th day of January, A. D. 1886.

JOHN R. LA\VItENOE.
