PENDANT-BOW.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed August 20, 1910. j Serial No. 578,189.

['0 all whom it may concern:

Be it known that I, LOUIS E. F. lVAcHTnR, a citizen of the United States, and resident of Hartford, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Pendant- Bows, of which the following is a specification, reference being had to the drawings forming a part hereof.

This invention relates to pendant bows, for example such as the rings or bows for watches and other articles similarly suspended or secured.

It has particular reference to means for attaching such bows to the pendant proper or the projection on the article to be sus pended so as to securely hold the attached parts and at the same time permit the necessary freedom of movement.

It also has particular reference to the construction of the bow and the construction of the pendant head, with the object of making durable and strong construct-ions and economical in their production.

l Vhile there aremany varieties or changes in detail in bows and pendant heads, and a illustrated one form embodying my invention, as applied to a bow for a watch pendant, and the form I am about to particularly describe and which is shown in the drawings, is an antique bo'w which is the style now almost universally used, particularly in watches of large size.

In the drawings forming a part hereof Figure 1 is the piece of stock from which a bow is made; Fig. 1 shows the end of this stock which is tubular and spun to shape to form a socket. Fig. 3 shows the bow made from the hollow stock spun into shape and bent, before attaching to a watch; Fig. 3 is a section through the middle of bow Fig. 3. Fig. 2 is the stock from which bow is made, while Fig. 2 shows the next step in centering the end to form a socket; Fig. 2 shows the hemispherical drilled end prepared prior to the swaging or spinning down of the bow proper. Fig. 4 shows the end of a piece of tubing partly in section, to showthe form to which the tube is spun or swaged to form the pendant head. Fig. 5 shows the bow in place on pendant, part in section on av larger scale than other views.

In Fig. 5, A is the bow proper shown as a hollow bow with socket ends A; B is the pendant head shown in section fitted around and soldered to the pendant post C. On the end of B are the attaching knobs or balls B. The bow as shown in Fig. 5 is made from stock illustrated in Fig. 1, which is spun down to the right shape or swaged or hammered, leaving as in Fig. 1 the cup A at the end. After it has been bent to the right shape and tapered by swaging or spinning, it is then pressed throughout the middle portion to the form shown in Fig. 3 as a section through the middle portion. When bent into the complete bow, the ends constitute sockets oppositely disposed and facing inwardly, as shown A A, Fig. 3. This bow with the sockets is then sprung over the ends of the head B, as shown in a scale twice as large in Fig. 5, and the inner edges of the cups A are spun down by means of suitable tools so that they embrace the ball or knob project-ions B on the pendant. Made and attached in this manner insures a bow which cannot be sprung oif of the pendant and at the same time alfords an easy means of attaching, extremely simple and having no minute parts capable of derangement or liable to break, and with all a construction which may be economically made after machinery has once been provided there-for.

Figs. 2, 2 and 2 show the process of shaping the end of a how when made from solid stock, with the object of producing the socket A by cutting out the metal at the end of the rod, while the rod is then swaged or hammered the rest of its length, between the two ends, to the desired tapered shape 'asmay be required for any particular design of how. The bending of the bow is then similar to the bending of the hollow bow, and after it has been fixed to the pendant the edges of the socket A are spun over the ball at the end of the head, securing it against iel'noval and at the same time permitting the desired flexibilit; of the bow on the pendant. The method of making the pendant head is illustrated in Fig. 4, in which the end of a tube is shown in part section,this tube having been run througha swaging or hammering machine which swages the tube progressively, as it passes through the machine, into ova-l capsules like beads, leaving between each bead sufficient material so that they may be cut apart as indicated at X X in Fig. 4, and while being out apart, as the last process in the hammering or swaging maprising a small section substantially the chine, the end is rounded off so as to leave the swaging machine in the shape of a ball as shown on larger scale in Fig. 5 at B.

By the actual'working in metal, such as gold, gold-filled or silver, I have developed methods for constructing or producing bows and pendant heads embodying my invention, and by my actual experience have found the construction of bows and pendants according to my invention and method to be economical and capable of strong, accurate and secure production.

While the process of producing the heads as above described is illustrated in a form in which the head end is a knob encircled by a socket on the pendant, I also make pendant heads in this manner but leaving the end open to form a socket so as to embody my invention as set forth in Patent No. 916,809, March 30, 1909. Likewise the particular construction of hollow bow formed in section as in Fig. 3 can be used economically in a form in which the end is swaged or formed into a ball to be attached to a pendant having a socket end.

I do not desire to limit myself to precise details of construction shown and described herein, which represent particular forms of embodiment of my invention, as various modifications in dimensions and design are possible, still keeping the essential and novel features of my invention, but

\Vhat I claim and desire to secure by Letters Patent is: w

1. In combination in a pendant bow and head, a pendant having knobs integrally formed on diametrically opposite sides thereof, sockets constituting integral extremities to the bow and having the walls of said sockets forming a substantial part spherical interior configuration thinned at the open end whereby they are adapted to be spun or bent over the knobbed ends of the head forming a part ball and socket joint, whereby the bow is held against detachment and perfect fit of joint is secured irrespective of bending or variation in size of parts, entirely by material integral with the extremities of the bow.

2. A pendant bow for watches or like articles, made of tubular material swaged throughout its length with the exception of the ends, sockets formed on the ends comsame size as the original tube, said end sectlons being bent to face each other and adapted to embrace projections on a pendant proper and thereby form a ball and socket joint.

3. An article of manufacture comprising a tubular bow for watches or like articles, constrictions formed adjacent to each end of said bow and enlargements formed at the end in conjunction with said constrictions whereby a socket is formed of the walls of said tube at its ends, said ends being bent in juxtaposition, as and for the purpose described.

4. A pendant bow for watches or like articles, comprising hollow stock having a substantially triangular section about the middle, constrictions formed in said hollow stock adjacent to its ends whereby a seat is formed in sockets constituting the extremities of the bow and formed integral with the main portion thereof.

5. A head for watch pendants or the like, made from tubular stock swaged to the shape of the head and having the ends thereof brought close together and adapted to form part spherical extremities at the ends of said head.

6. In a watch, an antique pendant head having a hollow head spun to shape, having the extremities formed into part spherical projections, a bow made of hollow tubular material reduced toward either end with each extremity left substantially the origi nal size and formed to constitute a part spherical, inwardly directed projection at either end of said bow, adapted to engage the part spherical extremity of the head.

7. A head for watch pendants or the like, comprising a hollow body swaged from tubular material having its middle portion of maximum diameter, two diametrically opposite openings therein for reception of a pendant post, a separate tubular member constituting said pendant post complete passing through'said openings and secured in one thereof, tapered extremities on either end of'said body portion merging into enlargements at either end formed integrally of the tubular material constituting substantially spherical knobs.

Signed at New York, this 18th day of August, 1910.
