UNITED STATES PATENT OFFICEo ALBERT CHOPARD, OF MOUTIER-GRANDVAL, SWITZERLAND, ASSIGNOR TO THE SOCIETE INDUSTRIELLE, OF SAME PLACE.
STEM-WINDING WATCILTI.
SPECIFICATION forming part of Letters Patent No. 250,423, dated December 6, 1881,
Application led September 23, 1881. (No model.)
T 0 all whom 'it may concern Be it known that I, ALBERT CHOPARD, of Moutier-Grandval, in Switzerland, have invented an Improvement in Stem Winding Watches, of which the following is a specification.
The object of this invention is to simplify the construction of stem winding and setting watches, to lessen the cost of the same, and to obtain greater strength and durability in the parts.
In the drawings, Figure 1 represents the mechanism beneath the dial ofthe watch. Fig. 2 shows the rocker at the side next to the gearwheels. Fig. 3 is a sectionof the rocker at the line fr y. Figs. 4, 5, and 6 are detached illustrations of the rocker and gear-wheels in their different positions. Fig. 7 shows the plates and bridges of the watch-works. Fig. 8 shows the quarter-plate Without the stayplate, and Fig. 9 represents the under side ofthe stay-plate.
The burr or crown A of the stem-Winder is of usual character, and its stein pas-ses into the Watch; butinstead of being provided with the usual ratchet-wheels and gear wheels or pinions it is only provided with a gear-wheel, B, that gears into the teeth of the wheel c.
The rocker M is made with three arms, and the spring z acts against one of these arms. The rocker is pivoted upon a stud, p, Fig. 3, projecting from the pillar-plate of the watch, and the screw s, passing into such stud 19, retains the rocker in position, but allows it to be vibrated.
The wheel c is between the pillar-plate and the rocker M, and said rocker is recessed for its reception, and there is a tubular hub, o, upon the rocker-plate, that forms the arbor, around which the wheel c is revolved by the action of the gear B.
The pinion D is pivoted at y upon one arm of the rocker M, and its teeth are always in gear with the wheel c.
The arbor F ofthe spring-barrel has at one end a ratchet-wheel, H, between the quarterplate P and the stay-plate N. The pawl n and spring m are recessed in the plate P and retained in place by the plate N. At the other end the arbor F is provided with the gearwheel E, with which the pinion D remains in contact, except when the hands are being set; hence the crown A ofthe stern can be turned, as indicated by the arrow, Fig. l, to wind up the watch whenever necessary; but should the crown be turned the wrong Way, as indicated by the arrows, Figs. 4 and 5, the parts will not be injured, because the arbor F and wheel E will be held iirmly by the pawl or click n, and the rocker M will swing and the teeth of D separate from the teeth of E, as indicated in Fig. 5, in consequence of the inclined shape of the sides ofthe teeth and the tendency of the Wheel` c to swing the rocker M when turned in the direction indicated.
For setting the watch I make use of a pusher acting against the stud x upon the rocker M, to move such rocker M and Wheel D into the position shown in Fig. 6, and separate the wheel D from the wheel E and bring it into contact with the wheel G, that is part ot' the gearing ot' the hands. While the parts are held in this position by the pusher the crown of the stem-Winder and the gearing can be turned either way to set the hands forward or backward.
I claim as my invention- The combination, in a stem-winding mechauism, ot' the rocker M, pivoted upon the pillar-plate, the gear-wheel c, turning upon the tubular arbor o' of the rocker M, the wheel D, the arbor of which is upon the rocker M, the wheel B, the stern and crown or head A, the winding-gear E, and setting-gear G, substantially as set forth.
In testimony whereof` I have signed this specification in the presence of two subscribing witnesses.
A. CHOPARD.
