EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 351,623, dated October 26. 1886.

Application filed April 30, 1886.

To all whom it may concern:

Be it known that I, DANIEL V. BROWN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying 1o drawings, which form part of this specifica tion, in which Figure 1 is a perspective of a pair of eyeglasses embodying my improvements. Fig. 2 is an edge view or end elevation of inner 1 side of eye-wire on lens, showing keepers and stud. Fig. 3 is a perspective of bow or spring. Fig. 4 is a perspective of one of the nose-pieces. My invention has relation to eyeglasses the lenses of which are fittedin frames or eyewires. I My improvements have for their object to provide a construction in which the nose-pieces and bow or spring will be securely fastened to the eye-wires without the employment of screws, and in such manner that the parts may be readily detached or separatedwhen re quired.

My improvements consist in the peculiar construction and combinations of parts hereinafter fully described and specifically claimed.

Referring to the accompanying drawings, A A represent the lenses, having eye-wires. B B. Said eye-wires are formed or provided with keepers O C and D D, and they have also studs or pins 6 e. The keepers O C have each a sin- 5 gle opening, 0, through which pass the diminished ends f of the nose-pieces F, the latter having shoulders f, which form stops and limit the downward movement of said noses pieces in the keepers. The lower ends of the 4o nose-pieces being diminished, as described,

form dowels, which pass directly downward into the keepers O C on the eye-wires. The keepers D D have each two openings or slots,

d and d, one above the other. The upper 5 ends, f f of the nose-pieces pass through the slots (1, while the lower ends, 9 g, of the bow or spring G pass through the slots d. The upper ends of the nose-pieces have liberty of movement endwise in said openings d, but the 5o-ends of L the bows or springs are prevented 0 by a direct upward pull.

from moving by reason of the fact that the studs 6 e enter openings 9 g in said bow or spring, the latter being curved near its ends, as shown, in such manner that said ends tend to press constantly on the eye-wires.

To remove the bow or spring from the eyewires, its ends are lifted or sprung so as to clear the studs e e, and said ends are then withdrawn from the keepers D D. To remove the nosepieces, their upper ends, which curve upwardly, as. shown, are first bent or sprung down and then withdrawn from the keepers D D. The lower ends of the nose-pieces are then lifted out of or withdrawn from the keepers C 5 The construction described produces avery secure fastening of the nose-pieces, bow or spring, and eye-wires without the employment of any screws whatever, and at the same time permits the parts to be readily detached when required or desired. As the upper ends of the nose-pieces may be freely moved lengthwise in the keepers D D, said pieces readily yield or give, to accommodatethemselves to different shapes of noses, retaining sufficient pressure to insure, with the assistance of. the bowor spring, the retention of the glasses securely upon the nose.

The lower ends of the nose-pieces F may be prolonged some distance below the. keepers C, as shown in Fig. 4 of the drawings, and have openings f formed in them to receive studs h h on the eye-wires in the same manner as the bow or spring, which will prevent said nosepieces from being accidentally displaced by an upward push.

That I claim as my invention is 1. The combination, with the eye-wires B, having keepers C and D, of the nose-pieces F and bow or spring G, the lower ends of said pieces forming dowels which are inserted in the keepers O, and their upper-ends entering and having liberty of movement in the keepers D, the nose-pieces being separated or disconnected from the bow or spring, substantially as shown and described. I

2. The combination, with the eye-wires B, nose-pieces F, and bow or spring G, of the keepersD, having slots d for the reception of the upper ends of the nose-pieces, and slots d 100 for the passage of the ends of the bow or' spring, substantially as shown and described.

3. The combination, with the eye-wires 13, having keepers O and D and studs 6, of the ings in which said studs enter, substantially 10 as shown and described. I

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of 5 nose-pieces F and bow or spring G, said keep March, 1886.

ers D having two slots, (1 and d, for the passage of the ends of the nose-pieces and bow or spring, the latter being curved to cause it to press against the eye-wires, and having open- DANIEL V. BROWN. 'itnesses:
