sPEoTAoL'f's.

'1. Application filed Sentember 521, 1886. Seria T all whom it maly concern:

Be it known that I, CLEMENT B. BIsHoP, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Spectacles and Eyeglasses,

of which the following is a specification.

My inveution consists of certain improvements in the construction of spectacles, designed more particularly for facilitating and rc economizing their manufacture.

In the accompanying drawings, Figure 1 is aperspective view ofa pair of spectacles,illustrating one of the features of niy invention, the temples being broken off. Fig. 2 is a view of a modification. Fig. 3 is an enlarged perspective view illnstrating the construction of the end pieces. Fig. 4 is a view illustrating the mode of prodncing half of one of the end pieces. Fig. 5 is a perspective view, also drawn to an enlarged scale, of the end of one of the temples.` Fig. 6 is a sectional view of the same, illnstrating its position in the end piece. Fig. 7 illustrates a modification of the same.

In the manufacture of spectacles one of the chief elements of expense is the filing which has to be done on the different parts, and more particularly the end pieces.which are attached to the ends of the rims. The punching out of these end pieces leaves sharp corners, which have to be filed down.

It is one of the objects of my invention to so const-ruct the end pieces as to dispense with this filing so far as possible.

It is a further object of my inventon, in applying it to rolled plated spectacles, to produce an article in which all the exposed parts shall be plated.

Heretofore. so far as I am aware, it has been 40 found impossible to produce plated spectacles without leaving some exposed part without plating, and more partieularly the edgcs of the end pieces to which the temples are connected.

I attain these objects-that is, I dispense with the filing of the end pieces, and when making plated work produce end pieces with all the exposed parts plated, by striking these.

end pieces np With rounded surfaces, as shown in Figs. 1, 2, and 3. i

a o. 372,954, dated November 8,1887.

'0. 214,130. (No model.)

Referring to Figs. 1 and 2, A A are the usual rims of the spectacles, split at one end, a, to which the two halves of the end pieces B are soldered, the two halves of these end pieces being of such a Character that they can be united or fastened together by means of a small screw, which thus secures the ends of each rim. I form these end pieces B of two halves, b b', Fig. 3, WhichI strike up With rounding surfaces by means of a punch 'and die, as illustrated in Fig. 4, so that when the two are united by means of the screw d, Fig. 3, they form an end piece of a rounded or substantially spherical form. As a general rule, the end piece will be in the shape of a fiattened sphcre or ovoid; but I do not limit myself to any precise shape, so long as each half is struck up with a rounding surface to avoid corners, which might need filing.

In using plated stock to form the end pieces this method 'of striking up the halves With rounded surfaces enables nie to leave a plating over the entire surface, as Will be understood on reference to Fig. 4, where the dark line o indicates the plating. piece such vas described, whether made of steel or of plated stock, can be readily distinguished from one which has been shapedi by the old filing process, owing to the appearance given to the article by the Shaping-die in striking' up the end piece. Such appearance will be best understood by. those skilled in the art vby the use of the descriptive phrase struek up), The adjoining flat faces of the two halves of the end pieces are milled out in any desired way or by any desir'ed means for the reception of the flattened ends of the temples',or the necessary recesses may be formed in the two A struck-up end ssi halves of the end pieces in the punching opera- In order to get a sufficient frictional contact between the flattened end of the tempie and the two halves of the end piece, I split the flattened end c of the tempie E at an angle, as illnstrated in Fig. 5, and bend the two split ends slightly apart, so as to form a species of spring,which,when the tempie endy is inserted between the ends b and b', is compressed by the latter.

To form a stop to prevent the tempie E from being turned beyond theposition at right angles to the glasses, the milled-ont portion of one or both of the half end pieces, Z) b', may, as shown in Fig. 3, be provided with a straight portion, f, against which the corresponding straight portion on the eye e of the tempie bears when turned out to the position at right angles to said glasses, as illnstrated in Fig. 6; or corresponding shouldersf' may be formed on the end piece or pieces and the eye of the temple, as illustrated in Fig. 7.

Eyeglasses have heretofore been made with rounded end pieces on the rims; bnt,so far as Iam aware, in all such cases such ronnding has been produced by the tedious filing process solely for the purpose of neater finish in the more expensive grades of these eyeglasses. In my speetacles and eyeglasses the end pieces are punched np in a ronnding form, and this punehing up of the end pieces in ronnding form has the specific mechanical pnrpose of thereby dispensing with the expensive and tedions filing heretofore necessary.

I elaim as my invention- 1. A spectaeie-rim having end pieces with struck-up ronnded surfaces, snbstantially and for the purpose described.

2. The combination of the end pieces of a pair of specfacles with teinples having eyes e, split substantially as described.r

In testimony whereof I have signed my name to this specification in the presence of two snbscribing witnesses.
