PATENT OFFICE.
WATCH-CASE PENDANT.
SPECIFICATION forming part of Letters Patent No. 357,195, dated February 8. 1887,
Application filed February 10, JFSG. Serial No. 101,516. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES K. Guns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in lVatch-Gases, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a central sectional view ofa construction embodying my invention, the winding stem or key being in its extreme inward position. Fig. 2is asimilar view showing the winding stem or key withdrawn; Fig. 3, an
elevation of the winding stem or key and itsspring or brake detached, and Fig. 4 is a plan section, taken on the line :20 m, Fig. 3.
Like letters refer to like parts in all the figures of the drawings.
My invention relates to watch-cases, and more particularly to the construction of the pendant and windingstem of that description of watches known as stem-winding, its object being to provide a simple and eflicient means for holding the stem in any position in which it may be placed and preventing accidental movement of the same.
I will now proceed to describe a construction in which I have practically carried out my invention in one form, and will then point out more particularly in the claims those features which I deem to be new and desire to protect by Letters Patent.
In the drawings, A represents a portion of awatch-case, of any usual construction, and B the pendant thereof. This pendant is provided with the usual aperture, B, to receive the winding-stem, which aperture is preferably reduced at its inner end, thereby forming a shoulder, 11.,
0 indicates the winding-stem, which is screw-threaded at its outer end toreceive the crown D, which fits over the end of the pendant, as shown. The inner end of the winding-stem is provided with any approved means for connecting it with the watch-movement-- such, for instance, as the square socket 0, (shown in the drawings,) or the usual square pm.
It will be observed that the winding-stem is considerably less in diameter than the aperture of the pendant through which it passes,
and in order to guide the said stem and hold it properly in positions, I employ a hollow sleeve or block, E, of an external diameter substantially equal to the diameter of the aperture in the pendant, within which it fits snugly, being secured in position in any suitable manner. In Fig. l of the drawings this sleeve is shown as held in position by means of thering F, the ends of which pass through the pendant and enter a groove, f, in the sleeve, thereby preventing any longitudinal movement of the same. In Fig. 2 of the drawings the sleeve is secured by means of a screw, f, which passes through the pendant and into the sleeve. Any other suitable manner of securing the sleeve may be adopted. The lower portion ofthe sleeve is reduced in diameter to correspond to the reduced portion of thea-perture B of the pendant, thereby forming a shoulder, f upon the sleeve, which rests upon the corresponding shoulder, b, of the pendant, thereby forming a seat for the sleeve.
The sleeve E surrounds the stem 0, which passes through the sleeve in such a manner as to be capable of a freelongitudinal movement therein. This longitudinal movement of the stem is necessary, of course, in order toe-nable the stem to be withdrawn into the pendant when it is desired to insert the watch-movement in the case or withdrawit therefrom. In order, however, to hold the stem in any posiaccidental displacement of the same, a brake is necessary, and. this I provide by means of a spring formed integrally with the sleeve E, and bearing upon the stem 0 in such a manner as to hold it by means of the frictional contact between vthe two in any desired position. This brake or spring is constructed by :lormingin the sleeve an L-shaped or similarly shaped slot, 0, thereby forming a tongue, E, which is elastic and bears upon the winding stem, acting, by reason of its frictional contact, as a brake, in the manner hereinbefore described.
It will be observed that the construction just described is extremely simple and cheap, the parts being readily manufactured and easily assembled, while at the same time the device is effective in its operation and durable. It is obvious, moreover, that various modifications in the details of construction may be made tion to which it may be moved, and prevent 2. The combination, with the pendant and I 5 stem, of the sleeve E, surrounding the stem and arranged within the pendant, the said sleeve being provided with the groove f and the ring F, having its extremities arranged to engage with the said groove, substantially as 20 and for the purposes set forth.
CHARLES K. GILES.
