. WATCH-PENDAN '1.

Specification of Letters Patent.

Application filed. August 3, 1920. Serial No. 401,044..

To aZZ whom it may comer-n Be it known that I, Louis E. F. VvAGI-ITER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Watch- Pendants, of which the following is a specification.

My invention relates to certain new and useful improvements in watch pendants, and the principal object of my invention is to produce a construction in which deep openings in the pendant may be used for the ends of the bow, and also to enable a bow of such strength to be used to prevent the ends of the bow coming out of the recesses either by the bending of the bow or the springing of the sides, and also to provide means. whereby when desired the bow may be readily disconnected from the pendant and removed without the necessity of bond ing or springing the bow.

With these and other objects in view my invention consists in certain constructions, combinations and arrangements of parts several forms of which will be first described in connection with the accompanying drawing and then the invention particularly pointed out in the appended claim.

Referring to the drawing wherein I show several forms of this invention and wherein the same part is designated by thesame ref erence numeral wherever it occurs,

Figure 1 is a central longitudinal section through a pendant employing my invention with parts shown in elevation;

Fig. 2 is a central longitudinalsection through a slightly modified form of constructlon from that shown in Fig. 1;

Fig. 3 is a central longitudinal section through a pendant showing a still further modification in which the bow is provided with ball ends;

Fig. 4 is a sectional longitudinal section through a pendant covering another modification in which the bow is also provided with ball ends, and

Fig. 5 is a plan view of one member forming the pendant.

In Fig. 1 the pendant comprises a body portion 10 centrally bored to receive the stem of the watch. Formed on this body portion is a collar 11 of any desired shape, said collar being located intermediate the ends of the body portion. Above the collar the body portion is shown as slightly enlarged at 12, and then at its upper end provided with a reduced screw-threaded portion 14. Mounted on the body portion and resting with its lower surface on the upper surface of the collar 11 is a ring 15 shown in detail in Fig. 5, this ring being provided at diametrically opposite sides with the semicircular depressions 16. 17 is a second ring similar-in construction and shape to the ring. 15. The rings 15 and 17 are together of such a thickness as to equal the height of the enlarged portion 12 of the pendant and are mounted thereon.

18 is a nut threaded to engage the threadedportion 14 of the pendant and hold the rings 15 and 17 securely in position. In assembling the parts the ring 15 is first placed over the portion 12 with its lower surface resting against the collar 11. The ends 19 of the how 20 are then placed within the depressions 16 while the rings 15 and 17 are separated and then the two rings brought together. Then by screwing the nut 18 on to the threadedportion ,17 and turning it down tight the parts will be securely held in position. It will thus be seen that the grooves 16 may be made of ample depth to give the ends of the bow ample bearing surface, and thatthe body of the bow can be ofample thickness to prevent any springing of the bow which would permit of the ends 19 coming out of the bearings 16 in the rings 15. i

In the modification shown in Fig.2 the body portion of the pendant is formed with a flange 21 in which are formed the bearing grooves for the ends 19 of the'bow 20.

22 is a ring provided with grooves to form the other halfv of the bearings for the ends 19. This ring is held in position bya nut 1 23 as described in connection with the form shown in Fig. 1. It will be seen that the only diiference between the forms shown in Patented July 5, 1921.

In Fig. 3 the pendant comprises the body portion 10 having the collar 11 formed integral with the body portion. Resting upon the top surface of this collar is a'ring 2 1 having depressions 25"formed on diametrically opposite edges to form bearings for the ends of the how 26, the ends of the bow in this case being shown as formed into balls 27 and the bearings in the collar 24 being of a shape to partially surround the balls.

28 is a second collar similar in shape to the collar 24: and having corresponding depres sions 25 in opposite sides of its circumference, so that the two depressions will'together form complete bearings for the balls 27 of the bow 26.

The pendant is provided, as in Figs. 1 and 2, with a nut 29 to hold the rings 24 and 28 together, and thus lock the balls 27 on the ends of the bow in their bearing sockets.

In Fig. 4 I have shown a construction very similar to Fig. 8, in which the pendant coinprises the body portion 10 and has a collar 11 thereon, on theupper surface of which is mounted the ring 24: having the depressions 25 in opposite sides thereof for the balls 27 on the ends of the bow 26.

I also provide a second ring 28 having depressions corresponding to the depressions 25 in the ring 21, the two rings being held together by the nut 29 screwed on the threaded upper end of the body portion 10 of the pendant.

It will be understood that the balls may be omitted from the ends of the bows in the constructions shown in Figs. 3 and 4-, and also that such balls may be used if desired in connection with the constructions shown in Figs. 1 and 2.

It is to be noted however that in all the constructions shown the bearings for the ends of the bow are made in two halves into which the ends of the bow may be inserted without springing the bow or changing the shape of the bow after the ends are in place, and then the two halves secured into position to form bearings for the ends of the bow. Also that a crown may be applied to the pendant with a portion overlapping the outer surface of the nut or ring 18, 23, or 29, which ring will then act as a guide to the crown in its revolutions.

Considerable variation of the details as described herein may be resorted to without departure from the spirit of the invention which is to be construed in the light of the following claim.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

A watch pendant, comprising, in combination, a body portion having a plane upper surface and comprising semi-spherical bear ing projections extending diametrically from the main portion thereof, said projections each having a substantially semi-spherical depression in its plane surface, a cylindrical portion extending above said plane surface, a removable body portion having a plane surface adapted to fit on said first named surface, and bearing projections and depressions to register with the first named bearing projections and depressions, said removable portion fitting over said cylindrical portion and a cylindrical retaining ring secured to the projecting end of said cylindrical portion to hold the pendant in assembly, and providing an outwardly cylindrical surface standing above the assembled pendant.

In testimony whereof I aflix my signature in the presence of two witnesses.
