STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 357,322, dated February 8, 1887.

Application filed July 24. 1886.

T0 at whom it may concern:

Be it known that I, JOHN JOHNSON, of Ba ton Rouge, in the parish of East Baton Rouge and State of Louisiana, have invented certain new and useful Improvements in Stem finding and Setting -Watches, of which the following is a specification.

This invention relates to certain improvements in the patent granted to D. H. Church, for a stem winding and settingwatch, No. 280,719, dated July 3, 1883, the improvements permitting the application of the winding and setting devices to any size of watch, large or small, and the convenient inserting and removing of the movement into and from the ing and setting watch in which the winding and setting devices are actuated by the winding-stem and an intermediate slide-piece in said stem, which slide-piece actuates a fulcrumed and springactuated lever at one side of the main plate of the movement. The lever engages by an arc-shaped shoulder or projection a pin secured to the pivoted and springactuated yoke that carries the winding and setting wheels, said pin passing through a slot of the main plate of the movement, so as to be in the path of the fulcrumed lever.

The invention consists, secondly, of a recessed post and a V-shapcd spring, which is engaged at one end by said post, and which is connected at its other end with the transmitting-lever of the winding and setting yoke, as will more fully appear hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 represent a front elevation of my improved stem setting and winding watch, shown with the dial removed and with the winding and setting devices, respectively, in position for winding the springbarrel and for setting the hands. Figs. 3 and 4 are rear elevations of my improved watch, showing the lever for setting the pivoted yoke carrying the winding and setting wheels; and Fig. 5 is a rear elevation showing the transmitting-lever in position for setting the yoke for winding only.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the winding-stem of my improved stem winding and setting watch; 13, the winding-pinion of Serial No. 20?,912. (No model.)

the same, which is turned by said stem, and B a slide-piece located in the tubular stern of the winding-pinion, as will appear more fully in the patent granted to D. H. Church, heretofore referred to. The lower end of the slidepiece B rests on one arm of a fulcrumed angular lever, D, the other arm of which is engaged by a spring, D, which is preferably made of fork shape, one end of the same resting against a fixed screw-stud, b, while the other end of the same engages the recessed end of the lever D, as shown clearly in Figs. 3 and 4. The fork-shaped spring Dis attached at its apex to a post, 6, of the main plate of the movement.

That arm of the lever D which is engaged by the spring D is provided with a short areshaped shoulder, d, concentric to the fulcrum of the lever D, said shoulder acting upon a pin, 6, that is secured to an oscillating yoke, E, at the other side of the main plate of the movement. The yoke E carries the usual winding and setting wheels, 6 c, and an intermediate crown-wheel, e which meshes with thewheels e and c", the yoke turning on the center portion of the crown-wheel 6 as customary in stem winding and setting watches of this class. The pin or stud 0 passes through a slot, f, of the main plate F of the watch-movement, said slot being made arc-shaped, corresponding to the motion imparted to the pin 6 by the yoke E. The yoke E is acted upon bya spring, 6, to the tension of which it responds at the moment when the pressure of the lever D on the pin or stud e is released. u

WVhen the windingstemA is depressed and the slidepiece B pushed down, the lever D is oscillated on its fulcrum, so as to release the pin e and permit the yoke to follow the tension of its spring 0*, and place the windingwheel 6 into mesh with the gear-wheel of the spring-barrel, as shown in Figs. 1 and 3. In thisposition of the fulcrumed lever D tension is imparted to the free arm of the spring D,

so that when the winding-stem is pulled out ICO wheels and be retained in this position as the pin or stud e rests against the shoulder at of the lever, as shown, respectively, in Figs. 2 and 4. The spring D holds the lever D and the yoke E in this position until the winding-arbor A is depressed again and the position of the yoke changed, so that its winding wheel meshes with the gear-wheel of the spring-barrel.

WVhen the movement is removed from the ease, the winding and setting device is in mesh with the hand-setting wheels, which is also the case when the winding-stem is pulled out. When the movement is put back in the case, the winding-stem is pushed in and the fulcrumed lever D pressed downwardly, so as to release the pin or stud e and move the yoke E byits springin position for winding the springbarrel.

By arranging the shoulder dot the lover D, so that it} forms an arc of a circle, of which the fulcrum of the lever D is the center, the pin of the oscillating yoke is readily engaged by or disengaged fiorn the fulcrnmed lever D, so as to shift the yoke and the winding and setting devices.

For the purpose of permitting the winding up of the spring-barrel and setting the movement going while the same is removed from the case, the screw-stud b has a recess at its base, which recess 1) engages the adjoining end of the forked spring when the screw-stud b is turned toward the spring. By turning the screw-stud b in opposite direction, the recessed base of the stud b carries the spring along and retains it in the position shown in Fig. 5. In this position of the spring D the lever D is moved sidewise, so that its shoulder clears the pin 0 of the yoke E, which latter is shifted by its spring 0, so that the gear-wheel e is thrown into mesh with the winding-wheel of the spring-barrel. The movement can then be readily wound and kept running as long as the screwstud b retains the lever-spring Din position. When the movement has been put into the case, the screw-stud b is turned on its 1 axis until the recess b releases the spring D,

quired. By thus controlling the position of the lever D and spring D the stem winding and setting device does not interfere in the least with the manipulationsof the movement and can be applied to movements of any size.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the winding-stem, a loose slide-piece located in the same, and the winding-pinion on said stem, of a fulcrumed lever one arm of which is engaged by said slide-piece, a spring engaging the other arm of the lever, said lever having a shoulder, a pivoted and spring-actuated yoke located at the other side of the movement, having a pin passing through a slot of the main plate into the path of said shoulder, and winding and setting gear-wheels on said yoke, substantially as set forth.

2. The combination, in a stem winding and setting watch, of a fulerumed lever actuated by the winding-stem, said lever having a shoulder, an oscillating and spring-actuated yoke provided with the winding and setting devices and with a pin that passes through a slot of the main plate into the path of said shoulder, a fork-shaped spring which engages by one end the fulcrumed lever, and a setting device that engages the other end of the forked spring and causes the setting of the yoke into position for winding the movement, substantially as set forth.

3. In a stem winding and setting watch, the combination of a fulcrumed lever actuated by the winding-stem,said lever having ashoulder, an oscillating and springactuated yoke provided with the winding and setting gearwheels and with a pin that passes through a slot of the main plate into the path of said shoulder, a fork-shaped spring of which one end engages the fulcrumed lever, and a screwstud having a recessed base adapted to engage the other end of the fork-shaped spring, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses.

JOHN JOHNSON.
