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

WATC H -BOW FAST EN E R.

SPECIFICATION forming part of Letters Patent No. 501,210, dated July 11, 1893.

Application tiled November 29, 1892. Serial No. 453,526. (No model.)

To all whom it may concern:

Beit known that I, FRITZ MINE, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Watch-Bow Fasteners, of which the following is a specification.'

My invention relates to watch bow fasteners; and consists of certain improvements which are fully set forth in the following specification and are shown in the accompanying drawings.

It is the object ot' my invention to provide a watch case with a convenient and economical device for fastening the ends of the bow to the pendant of the case, so that the watch may not be wrenched from the bow eitherl by accident or design, and the bow while securely fastened, may have the usual freedom of swinging movement upon the pendant.

It is also my object while providing such a fastening device to preserve the usual neat appearance of the watch, and to permit the bow to be easily disconnected from the pendant when desired for the purpose of making repairs.

In carrying` out my invention I employ a pendant provided with laterally projecting arms, on which are carried rotary sleeves suitably held upon the projecting arms, and a bow provided with eyes upon its end fitted upon the rotary sleeves and secured thereto in a suitable manner, so that the ends of the bow are fastened to the arms of the pendant through the medium of the rotary sleeves the latter being free to turn upon the arms when the bow swings.

I shall now refer to the drawings for the purpose of more particularly describing my invention.

Figure l is a longitudinal vertical sectional view of the pendant of a watch case having a bow with its ends secured by my improved fastening device. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal vertical sectional view of a pendant and bow similar to Fig. 1, illustrating a modification of my invention.

A is the pendant of the watch case.

B are laterally projecting arms carried by 5o the pendant.

It is immaterial to the invention whether these arms are integral with the metal of the pendant as in Fig. l, or separate and subsequently attached thereto as in Fig.

3. If the arms B are made separate they may be secured to the pendant in any convenient manner. In Fig. 3 they are shown screwed into the pendant.

O is the bow provided on its ends with eyes D. The eyes D are of larger diameter than the arms B so that they may pass over the arms.

E are intermediate tubular sleeves carried bythe arms within the eyes D on the ends of the bow and free to rotate upon the arms B. The sleeves E may be held upon the arms B in any convenient manner, preferably by heads b on the ends of the arms as shown. If the heads b are solid upon the ends of the arms and the arms are integral with the pendant, as in Fig. 1, the tubular sleeves E may be split, as indicated in dotted lines in Fig. 2, so that they may be placed upon the arms within the heads b before the ends of the bow are passed over` them. The heads b may however be formed by upsetting the metal on the extremities of the arms. The splitting of the sleeves E is then unnecessary. It is also unnecessary when the arms are made separate and subsequently secured to the pendant.

The eyes D of the bow are secured to the sleeves E in any convenient manner, preferably by a detachable connection so that the parts may be separated for purposes ot' repairs.

In Figs. 1 and 2 I have shown one form of fastening device consisting of pins or screws e, e, passed through tangential bores d formed between the eyes D and sleeves E. Vhile two pins or screws on each end are shown, it is apparent that only one might be used, but two are preferable when the sleeves E are split.

In Fig. 3 I have shewn screws C screwed down through the metal of the ends of the bow into the tubular sleeves.

It will be seen that the eyes D of the bow are securely fastened to the rot-ary sleeves E, which are free to rotate upon the arms B but are held thereon by the heads b. The eyes of the boW are of sufficiently large diameter to pass over the heads b, so that the boW may be detached from the pendant for any purpose by simply detaohing its ends from the sleeves E.

While I prefer such details as have been shown I do not limit myself to them as they may be varied Without departing from the invention.

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

1. The combination With the pendant of a Watch ease provided with laterally projecting arms, rotary sleeves carried by the arms and held thereon, and a bow having its ends provided With eyes fitting over the rotary sleeves on the arms of the pendant and direetly secured to said sleeves.

- 2. The combination with the pendant of a watch case provided With laterally projeoting arms having heads upon their extremities of rotary sleeves carried by said arms within the heads, and a bow having,` its ends sleeved upon the rotary sleeves and fastened to them.

3. The combination with the pendant of a Watch oase provided with laterally projecting arms having heads upon their extremities of longitudinally split rotary sleeves carried by said arms within the heads, and a boW havingits ends sleeved upon the rotary sleeves and fastened to them.

4. The combination with the pendant of a watch case having arms B provided With heads b of sleeves E upon the arms Within the heads and free to turn upon the arms, a bow having,` its ends D sleeved upon the sleeves E, and removable fastenings uniting the bow ends D and the sleeves E.

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