Specification of Letters Patent.

Patented March 80, 1909.

Application filed July 18, 1905. Serial No. 270,222.

To all whom it may concern:

Be it known that I, LOUIS E. F. Nacn'rrn, a citizen of the United States, and resident of Hartford, in the count 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 drawing forming a part hereof.

This invention pertains to pendant bows such as the'rings for watches, and has more fi 'urin in an sense the a earance of the resultant construction.

I, I a While T have invented various forms of pendant attaching means, the present one is intended, more particularly, to be used in the manufacture of Watch cases and parts as distinguished from the replacementof bows hy dealers or watch repairers, although in certain forms my present construction may be well adapted for replacements.

It well known that practically all watches are secured to a chain or fob, by means of a metal bow with pin or peg ends which enter the pendant head of 'the watch a very short distance, and are held in it simply by the spring in the metal, so that a slight lateral strain very frequently detaches the pendant, causingaccident or loss of the Watch. T

Various means have been suggested for attaching pendant bows more securely, but these have invariably been in connection with a cylindrical pendant head, and aside from my other inventions in pendant bows, no ractical construction has appeared which, in all respects, will meet the requirements. The'variou's suggestions in the past have been impractical owing to their involving excessively large parts or very fine work, which in the past have proved imracticable thou h many attempts have een made to utilize them. My invention is intended to avoid all these defects in pre-' rious suggested constructions. It is pri marily intended for what are now generally known as antique pendants, namely, such as have an elongated head.' These antique bows are now almost universally used, especially on all except the very largest sizes of watches.

in the drawings forming a part hereof, I have shown in Figure 1, the side elevation enlarged of a pendant head and bow on the top of a watch case. In Fig. 1, I have. shown in part section one end of the elongated pendant head. In Fig. 2, I have shown an elongated pendant head with adjacent parts broken away and showing part section the attaching means. In Figs. 3 and 4, I- have shown respectively the pendant bow. end when larger, or when practically the same size as the adjacent portion of the ring proper.

In Fig. l, A is the how, the ends of which, E, are spherical and enterjthe ends ofthe elongated head C of the pendant proper, which is shown inthe form of theme! well-known antique style.

In Fig. 1 is shown one end of C in which there is the recess I) as made for the reception of end B of the how. In dotted lines is shown how the extremities of. C on the edge of the recess or opening D, are bent in or closed in as at a, so as to partially surround the end B of the how. This edge or extremity which left quite thin by properly proportioning the recess and the outer diameter of C 1 contract, by means of a special construction of piier, or spin it over the ball so that it comes. in close contact with the hall permit-ting the pendant A to swivel without binding, and still afiording' a relatively large wearing surface between the bow end and the pendant head, thus distributing the wear and preventingany looseness resulting from even very extended use. i

i lhile Fig. 1 shows the antique pendant head so proportioned that the finished construction does not reveal the means of attachment between how and pendant head, in Fig. 2 is a modified form in which the pendant head is formed with a thin wall E, for a considerable distance at each end bordering the recess D, so that the closing end of the pendant head on the knob or end of the bow permits slight pressure to put the bow inc and socket in perfect contact. This construction is also intended to reduce the total amount of metal necessary which is accomplished in certain styles or sizes, while at the same time leaving a spherical or ball end to the elongated pendant head indicating the ball-bearing construction. In thismanner I produce a construction which resembles the ball-bearing bow which I have introduced in trade, and in the construction anddimensions indicate the at taching means that I employ.

In Fig. 3 I show the end of a bow in which the knob B is larger than the adjacent portion of the bow proper; while in Fig. 4, the end B is formed by reducing the immediately adjacent portion of the bow so'that the end remains practically the same size as the bow roper. These two forms are adapted for di erent sizes or different styles of rings. The ring or how I make by stamping in dies from sheet. metal, which in some cases I find, for certain metals, peculiarly advantageous, while under other circumstances I fashion the bow from wire. In the manufacture of the bow or ring, particularly when stam ed from sheet, I secure a slightly greater dEansity in the knob or spherical'end, which results in the same being harder and therefore more durable. In

' some modifications I do not require that the bow end be entirely spherical, and it is also possible to modify the form of pendant'hcad in. many respects without departing from my invention. Difi'erent cases, such as solid gold or gold filled, or silver when employed in the manufacture of the head vary the requirements in order to secure proper relative hardness of the bow end and the head I do not desire to limit myself to precise details of construction shown and described herein, which represent in one form an embodiment of my invention, as various modifications in dimensions or design are possible which still embody'the essential and novel features of my invention, but

hat I claim and desire to procure by Letters Patent is:

1. In a watch an antique pendant head, a bow, knobs on the end of said bow, recesses in the ends of the antique head, the extremities of said head being bent inwardly to form a closed socket partially surrounding the bow ends.

2. In combination in a watch an elongated pendant head, a pendant bow with integral part spherical ends, sockets in the endsv of said pendant head whereby the bow ends are held against removal by the bending in of the outer extremities of the socket sides.

3. Means for attachment of pendant bow and head comprising a knobbed bow end and a recessed head having "thinned sides spun or bent-over the knobbed end of the 'bow substantially as shown and described.

4. In combination with a pendant .bow and a pendant :head, of connecting means be tween the two-comprlsmg shoulders on the ends of said how, and a one piece member comprising the pendant head with an integral overhanging portion'engaging'the shoulders on saidbow as and for the purpose described.

In combination in a watch, a single piece or integral pendant head, a bow with enlargement or knob at the extremities thereof, recesses in the integral ends of said pendant head whereby relatively thin integral extremities are produced capable of being bent or spun to engage the enlarged end of the bow to the extent of preventing its withdrawal from the socket.
