at some Letters Patent No. 96,387, dated November 2, 186:).
lMPROVEMENT IN sPnc'rAcLBs.
The Schedule referred to in these Letters Patent and making part ofthe same Be it known thatI, LOUIS BLACK, of Detroit, in the county of Wayne, and State of Michigan, have invented a new'and' useful I mprovemcnt in Spectacles;
' and Ido 'llereby declare that thetbllowillg is a full,
clear, and exactdescription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specificatiom This invention relates to a new and useful improvement in spectacles, whereby the glasses, or either of them, may be readily removed and other glasses inserted; and
The invention'consists in the construction and arrangement of parts, as hereinatter more fully described.
In the accompanying sheet of drawings- Figure 1 represents a front view of spectacles, constructed according to my invention.
-1 i gure 2 is a top view of the same.
Figure 3 is a sectional front view of spectacles, with the nose-piece attached to the how by a forked connection.
The other figures in the drawing represent details in the construction, which will be hereafter referred to.
Similar letters of reference indicate corresponding parts.
'A represents the bows;
B, the nose-piece; and
O O, the shanks, to which the templesD are attached, by joints, in the usual manner.
My object is to construct spectaclcsfand eyeglasses in such a manner that the glasses may bechanged at will. The glasses and frames or bows being made. of one size, they can be changed quickly and securely without the use of a screw-driver or anyother' tool. For} this purpose, I construct the shanks G O in two parts.
These parts are marked-d and 0.. b v (l is the large part, bearing the=hinge by which the temples are connected. I i
This part is notched or rebated to receive the end of the part c, the arrangement bcingplainly seen in the views, Figures 3 and 4.
To prevent the parts from slipping or getting out of place, I provide a dowel-pin, which is fixedto one part and enters a hole in the other part, as indicated in dotted lines in the drawing.-
To hold the parts together in this 'losition, I provide a box, clasp, ring, clip, spring. or slide, by which the parts are held firmly together. A
The ring or slide is simply moved forward over the two parts for holding them together, or back on the pzutd for releasing the part c.
Should the shank of thespectaeles he made round instead of a sliding ring, the ring may beascrew-nut, operating with the parts of the-shank, after the mannor of the colniIio'nhvatch-guard swivel.
Fig. 1 represents the shanks, secured together by hinged hox-clasps fiscen in lf-igures 5 and 6, the rererse sides of the clasp being shown in the two figures.
These clasps are hinged to the-large partd of the shanks, hythe hinge-rivets of tlic"temples D, and
may be placed either on the outside or inside of the' shank. When they are closed down over the shank, as represented in the drawing, the parts of the shank are firmly hold in the. desired position.
Figure 7 is a detail of the shank without any fastening.
In fig. 3, the nose-piece is attached to the bow A, by a forked connection, g, the bow being reversed with the fork, as seen at h. flhis arrangement allows of slight variations in thesizc of the bows, to suit thev varying sizes.
' The bows need not be reversed, as seen in the drawing, unless avariation in the size is necessary.
-1do not confine myself exclusively to hinging the clasp f to tho shank, as represented. It'may be connected with the temple, so as to hold the part's'ot' the shank together without any permanent attachment to the shank.
A spring, instead of thc clasp, may be arranged on.
the temple to producethe same result. Having thus described myinventiou,
I claim as new, and. desire to secure byLet-ter's Patent-- The bow A, open at both ends, but held at the inner by branches on 'the'nose-piece B, as shown in fig'. 3 of drawing.
. LOUIS BLACK.
