STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 413,654, dated October 29, 1889. Application filed February 12, 1889. Serial No. 299,651. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN H. FLINT, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Watches; and I do declare the following to be a full, clear, and exactdescription of the invention, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to those watches whose pendants are provided with longitudinally-shiftable stems or push-pins, which can be advanced for the purpose of bringing the winding mechanism into service and be retracted a limited distance when it is desired to operate the hand-setting mechanism; and my improvement consists in furnishing such watches with a tilting gear-wheel, that is inclined or canted as occasion requires. This tilting wheel is mounted on a short stud and is supported by a lifter, the movements of which latter are controlled by the stem. \Vhen the stem is advanced, this lifter raises the tilting wheel and throws it in gear with the winding mechanism; but the retraction of the stem inclines the lifter, thereby canting said tilting wheel to one side and causing it to mesh with the hand-setting mechanism of the watch. The arrangement of the tilting wheel is such, however, as to cause it at all times to be in gear either with a pinion driven by the stem or with an intermediate wheel driven by said pinion, as hereinafter more fully described.

In the anneXed drawings, Figure l is a greatly-enlarged plan of a portion of a watchmovement embodying my improvements, the tilting wheel being seen in gear with the winding mechanism. Fig. 2 is another plan of a portion of the watch after the tilting wheel has been detached from the stud. Fig. 3 is a similar plan afterthe lifter has been removed from said stud. Fig. 4 is a vertical section of the movement, the stem being advanced and the tilting wheel thrown in gear with the winding mechanism. Fig. 5 1s a similar section, but showing the stem retracted and the tilting wheel canted to one side and thrown in gear with the hand-setting mechanism.

Fig. 6 is a vertical section of the lifter, tilting wheel, and cap separated from each other.

A represents a portion of a watch-movement. B is the pendant of the same, and C is one of the customary plates of said movement, which plate carries the principal operative parts of my invention. D is a practically-oircular pit made in this plate, which pit slopes down toward the center of the watch and is provided with a short upwardly-projecting cylindrical stud E, tapped at e to admit a screw F, wherewith a disk-shaped cap G is secured to said stud. This cap has on its under side a short cylindrical neck g, of practically the same diameter as said stud, while the cap itself is adapted to enter a counterbore h in the upper surface of the tilting wheel H. h

is a central circular opening in this wheel to admit the neck g. Located beneath this wheel H, and suitably coupled to the stud E, is the lifter I, which is here shown as an annulus, having at one side a depending lug i; but this special construction need not be adhered to in every case, providing the proper lifting motion is effected. Lug t passes down through a slot 0 in the plate, which slot is located near the top of the inclined bottom of pit D, in order that the lifter I and tilting wheel Il may have a limited inclined or canted play on the stud E.

c is another slot in the plate C, this slot being arranged to admit a pinion J, whose hub j is traversed by a square arbor 76 at the inner end of the stem or push-pin K, which arbor slides freely within said hub, but cannot turn therein. Consequently the pinion must turn in unison with the stem.

L is the main windingwheel of the watch, and M is an ordinary ratchet of the same.

N is a wheel that gears with the cannonpinion O of the watch, said wheel N being situated in a lower plane than the windingwheel L and being preferably canted toward the tilting wheel H, as seen in Figs. 4 and 5.

In fitting this watch together the depending lug t' of the lifter is first inserted within the slot 0, and the tilting wheel H is then placed upon said lifter. The cap G is then inserted within the counter-bore of said wheel and secured in place by engaging the screw F with the stud E. The various parts being thus arranged and the stem K pushed in or advanced, which is the normal position of said stem, the arbor k strikes against the lug 'i, and thus swings the lifter I up to a horizontal plane, as seen in Fig. 4. This elevation of the lifter carries the tilting wheel H with it, the upward movement of the latter being restricted by the cap G, and when said wheel is thus arrested it is in gear with the winding-wheel L, as seen in Figs. 1 and 4. Consequently a proper turning of the stem K will cause its arbor k to revolve the pinion J, and thus set the wheel H in motion, which motion is transferred to the wheel L and results in winding the watch in the usual manner; but when the watch requires setting the stem K is retracted a slight distance, as seen in Fig. 5,which'act allows the lifter I to drop down and rest upon the inclined bottom of pit D, which dropping of said lifter causes a corresponding canting or inclination of the tilting wheel H and brings the lower edge of the latter in gear with the wheel N; but this canting of the wheel H does not throw its upper edge out of gear with the pinion J, and therefore when said pinion is properly turned by the stem K said tilted wheel will also turn and communicate its motion to the wheel N. This wheel will then turn the cannon-pinion O, and thus set the hands in the customary manner, after which act the stem is again advanced, so as to re-engage the tilting wheel H with the winding-wheel L, as previously described.

The lifter 1, whether made in the shape of a ring or pivoted lever, or otherwise, is preferabl flexible, in order that it may spring or give slightly when raised and brought in gear with the winding-wheel L. Therefore there will be no straining of the mechanism in case the teeth of wheel H do not instantlyengage with the teeth of wheel L. Finally, the devices herein described may be applied either to open-face or hunting-case watches.

I claim as my invention- 1. The combination, in a watch, of a winding mechanism, a hand-setting mechanism situated in a lower plane, a. tilting wheel driven by geared connection with the stem or push-pin, and a litter that actuates said tilting wheel and throws it in gear either with the winding or setting mechanism, said lifter being operated by said stem, substantially as herein described.

2. The combination, in a watch, of a winding mechanism, as L, a hand-setting mechanism, as N, situated in a lower plane, a tilting wheel H, turning upon the stud E and driven by the pinion J of stem K, and alifter I, fitted around said stud and having a lug i, operated by the arbor k of said stem, substantially as herein described.

3. The combination, in a watch, of pendant B, traversed by the stem or push-pin K, the plate 0, having a sloping pit D and a pair of slots 0 c, the stud E, projecting from said pit, a tilting wheel H, turning upon said stud and driven by a pinion J of said stem K, a litter I, fitted around said stud and having a lug 2', operated by the arbor 7c,winding mechanism, as L, and setting mechanism, as N, as herein described.

In testimony whereof I aifix my signatur e in presence of two witnesses.

EDWIN H. FLINT.
