WATCH-BOW FASTEN ER.

SPECIFICATION forming part 01 Letters Patent No. 459,133, dated September 8, 1891. Application filed August 23, 1890- Serial No. 362,847. (No model.)

To all whom it may concern:

Be it known that I, EDWARD O. CHAPPATTE, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Im- 5 provement-in IVatch-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.

My invention is intended for fastening the ends of a watch-bow in the pendant ofa watchcase, while allowing to the how the necessary freedom of motion or swinging movement.

In carrying out my invention I provide the pendant with holes or sockets on diametrically-opposite sides, in which the ends of the bow are journaled. The ends of the bow project through the metal of the pendant on the inside and are provided with holes, through which keys or pins are driven to look the bow ends positively in the pendant. The interior of the pendant adjacent to the holes or sockcts is countersunk or recessed, so as to allow the pins or keys to turn freely and also to lock them in the ends of the bow.

In the drawings, Figure 1 is a sectional side elevation of a watch-case pendant and a bow o embodying my invention. Fig. 2 is a horizontal sectional view of the same on the line was of Fig. 1. Fig. 3 is a vertical sectional view of the same on the line y y of Fig. 1. Fig. 4 is a cross-sectional elevation of the 3 5 watch-bow; and Fig. 5 is a side elevation of a portion of the same, illustrating a slight modification therein.

A is the watch-case pendant, which is provided on diametrically-0pposite sides with 4c holes or sockets B. The inner surface of the pendant about the holes or sockets B is countersunk or recessed, as shown at E.

O is the watch-bow, havingits ends 0 projecting through the holes or sockets B of the pendant. These ends cot the bowCare formed with 5 holes, through which are driven pins or keys D, extending transversely through the ends of the bow on the inner side of the pendant, so as to lock the bow therein. The countersunk or recessed portions E on the inner sur- 5o face of the pendant about the holes or sockets present fiat surfaces and permit the projecting ends of the pins D to turn freely without binding. The shoulder formed by these recesses also serves to prevent the pins becoming loosened and slipping from the holes in the ends of the bow.

In Fig. 5 the ends of the bow are shown formed with shoulders or offsets e, which fit against the outside of the pendant and lock the bow ends against inward movement.

\Vhile I prefer the minor details of construction here shown, I do not limit myself to them, as it is apparent that they may be varied without departing from the principles of the invention.

\VhatIclaim as new, and desire to secure by Letters Patent, is

In a bow-fastener, the combination of a watclrcase pendant provided with holes or sockets on diametrically-opposite sides, the inner surface of the pendant being countersunk or recessed about said apertures, a watch-bow having its ends inserted through said holes orsockets, and pins or keys cxtending transversely through the ends of the bow on the inner side of the pendant to lock the bow therein.

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

EDWARD C. OIIAPPAT'IE.
