.To all whom it may concern.:

Beit known that I, HENRY VENT, a citizen of the United States of America, residing at ig part of Letters Patent NG. 339,246, dated April 6,1886.

(Model.)

In the drawings, A represents the winding Wheel, and B the pinion mounted upon the arbor of the watch-hands. C is a pivoted Chicago, in the county of Cool; and State of yoke provided with acentral wheel, l), ar- 55 Illinois, have invented certain new and useful ranged to mesh with the winding-pinion E.

Improvements in Stem-Winding Devices for Mounted in arms of yoke O are wheels F G, Vatches, of which the followiiig is a speciarranged to engage, respectively, with windiication, reference being had therein to the ing-wheel A and hand-setting pinion B, acaccompanyingdrawings. cordiug to the position of the yoke O. rlhis fo ro My invention relates to improvements in yoke is also provided with a third arm, H, watrhes, and more especially to that class of upon which is mounted a pin, II, which passes watches in which the handsetti ng and windthrough a suitable opening in the plate L. ing mechanism is operated from a suitable Iivoted upon plate L, as shown in Figs. l, winding bar situated within the pendant or 2, is an arm, M, the free end of which is 65 stein ofthe watch.

rEhe object of the in vention is to arrange this windingllar in such a manner that there will be no positive connection between it and the mechanism employed for winding the watch forked, as shown, the pin K being inserted into such fork, and the arm itself being held in the position shown in Fig. 1 by a spring, N, unless some pressure is brought to bear upon it.

side of its pivot to that occupied bythe forked end referred to, this knob to be referred to hereinafter.

The winding-pinion E, hereinbefore referred offered.

The winding-bar Q, hcreinbefore referred to, is situated in` the watch-pendant, and at its outer or upper end is secured to the knob X, as is customary. This winding-bar is square in shape,and for almost its entirelength in the pendant is surrounded bya sleeve, Y, through which a square opening is formed longitudinally. There is secured to sleeve Ya springarm, Z, provided with a bent free end, which passes through an opening in the sleeve. and is adapted to engage with any one of three notches, a n n2, which are formed in one face of winding-bar Q. The winding-bar passes down through the pendant, and is adapted to enter the openingl in winding-pinion E when desired. .It will be understood that when the bent end of spring-arm Z enters one of the notches of the winding-bar the sleeve to which such arm is secured will revolve with the bar; but when any lengthwise movement of the winding-bar is desired the sleeve will remain stationary and the spring-arm enter one of the other notches.

The operation of t-he device will be readily understood. Vhen it is desired to detach the movement from the case, the winding-bar is drawn out until ihcspring-arm enters thelowerinost or innermost notch, the bar bei ngth us drawn out sufliciently to allow ofthe detachment of the movement, and the parts of the movement being so arranged that when thus removed from the case the winding niechanism will be in gear.

With the movement in the watch-case the normal position ofthe parts is such as to-still have the winding mechanism in gear,t.he winding-bar being pushed in until the spring-arm engages with the uppermost or outermost notch.

When it is desired to put the setting mechanism in gear, the bar is drawn out until the spring-arm engages with the middle notch, where the bar is held. This removes the pressure from bar R, which is then operated upon by spring XV. As this bar is moved its lugT contacts with the lug O of arm M, and -serves to operate the said arm, and through it and the intermediate connections the yoke C, the yoke being thus shifted and the setting mech-- anism put in gear.

In Fig. 5 I have shown a modified arrange ment and construction of parts. In this arrangement the arm M is provided with aprojection, b, at or about its center, there being a suitable notch formed upon this projection. The lug of bar R is done away with, and the forked arm of a bellcrank lever, A', is connected with the stud T of such bar, the remaining arm of such lever being arranged to operate the arm M. When the parts are in the position shown in Fig.5,the winding mechanism is in gear. By pulling the winding-bar out the pressure is removed from bar R, and such bar forced outwardly by a spring, B. this operation forcing one arm of lever A against the projection b of arm M, the end of such arm entering the notch of such projection, and the yoke C shifted to put the setting mechanism in gear. By pulling out the windingbar` still farther the arm of lever A/ is forced pastprojection b and the winding mechanism again put in gear by spring N.
