FRITZ MINK, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE KEYSTONE VATCH CASE COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 456,900, dated July 28, 1891.

Application filed April 9, 1891. Serial No. 388,203. (No model.)

' in Watch-BOW Fasteners, of which the following is a specification.

My invention relates to watch-bow fasteners; and it consists of certain improvements which are fully set forth in the following specification, and are shown in the accompanying drawings, which form a part thereof.

The object of my invention is to obtain a convenient, economical, and -neat device for fastening the bow to the pendant of a watchcase with the usual freedom of swinging` movement.

My invention is particularly adapted to that construction known as the antique pendant and bow, in which the pendant proper is provided with a surrounding shell or false pendant and the bow is made liattened or approximately elliptical in shape.

In the drawings I have shown my invention applied to this con-struction, though it is not necessarily limited thereto.

In carrying out my invention I split the ends of the bow, which are inserted in apertures in the pendant, and then by means of pins or screws inserted diagonally through the metal of Athe bow. I force apart these divided ends, so as to enlarge the extremities of the bow on the interior, and thus prevent the withdrawal of them through the apertures.

- The pin or screw which thus forces apart the tion of the same.

A is the watch-case pendant proper.

B is the bow.

C is the outer shell of false pendant surrounding the pendant proper and provided on diametrically-opposite sides with apertures c c to receive the split ends b b of the bow B.

D are pins or screws which are inserted through the metal of the bow, acting to force the split members apart. These pins or screws D are carried by one of the split members and press against the other, and are preferably inserted from the outside of the pendant, extending diagonally through one of the split members, as shown in the drawings.

The extremities of the ends h l) ot'y the bow B may be formed with iianges or slightlybulbous ends, so that when the pins D force the split members apart these flanges are brought over the inner edge of the apertures, as is shown in Fig. l.

I prefer the minor details of construction which are here shown; butthey may bemoditied, if desired, without departing from the invention.

That I claim as new, and desire to secure by Letters Patent, is-

l. A bow-fastening device consisting` of a watch-case pendant provided with apertures upon diametrically-opposite sides, a bow having its ends split on their extremities and in serted in said apertures, and pins or screws carried by one of the members of said split ends and bearing against the other to forcesaid split ends apart and prevent the withdrawal of the bow through the apertures.

2. A bow-fastening device consisting of a watcli-case pendant provided with apertures upon diametrically-opposite sides, a bow having its ends provided with lateral projections or flanges and split in their extremities and inserted in said apertures, and pins or screws carried by one of the members of said split ends and bearing against the other to force said split ends apart and prevent the withdrawal ot' the bow through the apertures.

3. The combination of the antique pendant of a watch-case, consisting of the pendant proper A, the surrounding shell C, having apertures c c, the bow B, having split ends b b, and the pins D D, all combined and operating substantially as described.

In testimony of which invention I have hereunto set my hand.

FRITZ MINK.
