SPECIFICATION forming part of Letters Patent No. 397,313, dated February 5, 1889.

Application filed June 21, 1888. Serial No. 277,749. (No model.)

Patented in France February 10, 1887, No. 187,194; in Belgium October 15,1887, No. 79,128, andin Germany January 5,1888, No. 42,809.

To aZZ whom it may concern.-

Be it known that I, HIPPOLYTE Seniirz, watch maker, residing at Reeonvillier, in Switzerland, have invented a new and useful Improvement in Stem-Vinding \Vatehes, (for which Letters Patent have been granted in France, numbered 187,191t, dated February 10,1887; in Belgium, numbered 79,123, dated October 15, 1887, and in Germany, numbered 42,809, dated January 5, 1888,) of which the following is a specification.

Stem-winding devices have been made in which there is a ring with internal teeth for communicating motion from a pinion on the stem to the gear-wheel upon the spring-ban rel. In this case it was necessary to have two pinions on the stem and interlocking ratchet-teeth.

In my improvement I make use of a ring with inclined or ratchet teeth and a single pinion on the winding-stem with ratchetteeth on one end and gear-teeth on the other end, thus dispensing with the second pinion and two sets of teeth, so as to simplify the construction and lessen the cost.

I11 the accompanying drawings, Figure 1 shows a plan View of the stem-windingmechanism as it is to be seen when the dial is removed, and Fig. 2 is a partial section showing the pusher of the hand-setting mechanism.

In both figures similar letters refer to similar pieces.

The plate A of the work is provided with a circular groove, A',in which an annular rack, B, is caused to revolve, and there are inclined or ratchet teeth on the inside of the same. Three screws fixed to the plate have their heads projecting over the rack B to prevent its lifting out of the groove A. Upon the square part of the stem 0 there is placed a sliding pinion, D, having at one end a range of inclined or ratchet teeth, (1', and on the other end a range of ordinary teeth, (Z

double-armed spring, E, bears with its arm 6 upon the upper border of the groove of the 5 sliding pinion I), and with its other arm, (5* which has the form of a click, it bears upon the teeth-range of B. The axis F of the mainspring-barrel is provided with a wheel, G, engaging into the teeth-range of B. The teethrange d being pressed into the teeth-range of 13 by the spring 6. it follows that if the stem is turned in the direction shown by an arrow in Fig. 1 the mainspring will be wound up, the rack l3 being turned in the same direction as the arrow, and causing thereby the rotation of wheel G. If one turns the stem backward, the sliding pinion works like a click.

To set the hands it is necessary to have the teeth-range (1 put into gear with the wheel II. To that effect there is attired underneath the the plate Athat is to say, between the plate A and the spring-barrel bridge-a lever, L,

Fig. 2, having a pivot, Z, and a hook, L, the

latter engaging into the groove of the sliding pinion D. A pusher, M, bearing upon the lever L, allows the pinion D to be put into gear with II, so as to set the hands by turning the stem in one direction or the other.

I claim as my invention 7 The combination,witlrthe spring-barrel and the wheel G, of the ring 13, having inclined or ratchet teeth on the inner edge thereof, the stem C and pinion D, having inclined or 7 5 ratchet teeth at one end gearing with the teeth on the ring B and gear-teeth on the other end, and the train of gear-wheels to the hands, and the spring 1, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HIPPOLYTE SCHUTZ.
