WATCH WINDING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 766,415, dated August 2, 1904. Application filed November 30, 1903. Serial No. 183,230. (No model.)

To all whom it may concern:

Be it known that I, JOHN BOND, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented certain new and useful Improvements in Watch Winding and Setting Mechanism; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled .in the art to which it appertains to make and use the same.

My invention is an improved watch winding and setting mechanism; and it consists in the construction and combination of devices hereinafter described and claimed.

One object of my invention is to provide a watch winding and setting mechanism which is dust-proof.

A further object of my invention is to provide a watch winding and setting mechanism which may be operated much more rapidly than the stem-winding and key-winding and setting mechanism now in common use.

In the accompanying drawings, Figure l is an elevation of a watch-movement provided with my improved winding and setting mechanism, the dial being removed to disclose the dial-plate and the winding and setting gears thereon and the case being shown partly in section to disclose the construction of the pendant and the stem. Fig. 2 is a detail transverse sectional view taken on a plane at right angles to that of Fig. 1. Fig. 3 is a detail sectional view taken on a plane intersecting the barrel and disclosing the coiled spring therein and the flexible element coiled on the barrelfor rotating the latter in reverse directions. Fig. 4 is a detail view on a somewhat enlarged scale, the same being a perspective view of the pendant and a sectional perspective view of the stem and crown. Fig. 5 is a detail sectional view showing the construction of the sectional arbor and of the barrel, which is fast to the revoluble part 4 of the arbor and revolves on the non-revoluble part 2 thereof.

In the embodiment of my invention I provide a barrel 1, which is mounted to revolve on the section 2 of an arbor 3, said arbor also having a tubular section 4, the latter receiv- 5 ingone end of the section 2, as at 5, and revolving on said section 2 and being fast to revolve with the barrel. The tubular section i of the arbor has its bearing in the pillar-plate 5, as at 6, and is provided with a projection 7 which extends beyond the dialplate and is angular in cross-section. On this cross-sectionally-angular projection 7 is mounted the gear 8, which engages a gear a.

A yoke b is pivotally mounted on the gear a and carries at one end the usual intermediate winding-Wheel c,- which is normally kept by a spring (Z in engagement with the mainspring winding-wheel e on the arbor f of the 1 mainspring. The usual cannon-pinion and 5 minute-wheel of the hand-setting train are shown at g it, respectively. Aninter-mediate wheel '2', which engages the wheel a, is moved by the usual well-known means into engagement with the wheel 7L when the yoke is moved 7 O l to disengage the wheel 0 from the mainspring Winding-wheel e and out of engagement with said wheel h when the yoke is in the normal position shown to engage the wheel 0 with the wheel a. The usual setting-lever 9 is also provided, which when drawn outwardly conmeets the gear 8 to the hand-setting train through the gears a 2', and when moved inwardly causesthe yoke I) to be moved by the spring (Z, so that the gear 8 is connected to the winding mechanism through the gears 60, c, and e. The section 2 of the arbor is nonrevoluble and is formed with an angular projection 10, which is fitted in an opening of angular form made in the inner or top plate 5 11 0f the watch. The barrel 1 is hollow and constitutes the casing for a coiled spring 12. Said spring has one end hooked to the barrel and has its inner end hooked to the non-revoluble section 2 of the arbor, on which the 9 barrel is mounted. The function of this spring, as will be understood, is to turn the barrel in one direction. A flexible element 13 has one end attached to and is wound on the barrel 1 and serves when drawn outwardly therefrom to turn the barrel against the tension of the spring 12 and to thereby also turn the gear 8 with the barrel, which gear, as

hereinbefore described, connects with the winding or setting gears, according to the position of the set-lever. spring 12, which causes the barrel to rotate when the flexible element 13 is released, is to cause said flexible element to be rewound or coiled on said barrel. Said flexible element is here shown as a flat metallic strap of suitable dimensions. It may be a cord or chain, as will be readily understood, without departing from the spirit of my invention; The outer end of the said flexible element extends through the pendant 14:, which has a cylindrical bore and is provided at its outer end with a bayonet-slot 15. The stem 16 is of cylindrical form, is fitted accurately in the cylindrical bore of the pendant to exclude dust from entering the watchcase, and is provided with an outwardly-projecting stud 17 which is adapted to enter the bayonet-slot of the pendant to prevent the same from rotating in the pendant and to also enable the said stem to be readily drawn outwardly from the pendant. The inner end of the stem is connected to the outer end of the flexible element 13, which serves when drawn outwardly by the stem to rotate the barrel 1, as hereinbefore described. Within the scope of my invention the said flexible element may be connected to the stem by any suitable means. I here show the stem as provided with a kerf 18, in which the outer end of the flexible element 13 is placed, and a screw-pin 19 extends through a threaded opening in the stem and also through an opening in the outer portion of the said strap or flexible element 13, thereby enabling, it to be readily detached from the stem when required. The stem has a crown 20, which is hollow on its inner side to enable it to fit snugly on the outer end of the pendant.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to'without departing from the prin- The function of the ciple or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a winding and setting mechanism, the combination of an arbor, having a non-revoluble section and a revoluble section, a barrel fast to the latter, revoluble therewith, and mounted to revolve on the non-revoluble section of the arbor, a spring to rotate the barrel in one direction, attached thereto and to the non-revoluble section of the arbor, a gear to operate the winding and setting gears,-

mounted on the revoluble section of the arbor to rotate therewith and with the barrel, and a flexible element connected to and coiled on the barrel and adapted when drawn therefrom to rotate the barrel and the gear, against the tension of the spring, the latter by revolving the. barrel in the reverse direction when the flexible element is released, acting to recoil the flexible element on the barrel.

2. A watch having a top plate provided with an angular opening, and a pillar-plate provided with a bearing opposite said opening, in combination with an arbor, having a nonrevoluble section provided with an angular projection fitted in the angular opening of the top plate and a revoluble section mounted in the bearing of the pillar-plate, agear to op,

erate the winding and setting gears, connected to and revoluble with the revoluble section of the arbor, a barrel fast to and revoluble with said revoluble section of the arbor and mounted to revolve on the non-revoluble section of the arbor, a spring in said barrel, attached thereto and to the non-revoluble section of the arbor, and a flexible element connected to and coiled on the barrel to rotate the latter against the tension of said spring.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN BOND.
