PENDANT WINDING AND'SETTING WATCH.-

SPECIFICATION forming part of Letters Patent No. 357,906, dated February 15, 1887.

Application filed August 29, 1885. Serial No.175,620. (No model.)

To aZZ whom it may concern.-

Be it known that I, DUANE H. CHURCH, of Newton, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Pendant WVindin g and Setting Watches, of which the following is a specification. V

This invention relates to stem winding and setting watches in which the swinging yoke carrying the pinions, which respectively communicate motion from the crown-wheel, actuated by the rotation of the winding-stem, to the mainspring-barrel in winding, and. to. the dial train in setting the hands, is normally held in its winding position by a spring, and is moved to its hands-setting position against the stress of said spring by a longitudinal movement of the winding-stem.

The object of this invention is to provide simple and effective means whereby an outward endwise movement of the winding-stem is caused to move the yoke from its winding to its hands-setting position; and to this end it consists in the combination, with the yoke and the winding-stem, of a pivoted arm or lever engaged with the winding-stem, so as to be oscillated on its pivot by the inward and outward endw-ise movementsof said stem, and

a stud or pin on the yoke bearing againstsaid lever, the arrangement being such that an outw ward lengthwise movement of the windingstem Will cause the lever to swing on its pivot, and by its contact with the stud on the yoke move the latter to its hands-setting position, the lever being so moved by the inward movement of the winding-stem as to release the yoke and permit its spring to restore it to its winding position, all of which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figures 1 and 2 represent, respectively, front and rear views of a portion of the pillar-plate of a watch-movement provided with my improvement, the yokebeing shown in its hands-setting position. Figs. 3 and 4 represent similar views showing the yokein its winding position. Fig. 5 represents a longitudinal section through a part of the winding-stem, top plate, and pillar-plate, showing the means for holding the inner end of the winding stem stationary while the main portion of said stem is being secured to it.

In the drawings, a represents the yoke, which is pivoted to the pillar-plate b, as usual, and carries at one endthe pinion e and at the other end the pinion f, said pinions meshing with the crown-wheel g, which is rotated by the winding-pinion i, the pinion e meshing also with the main wheel j on the mainspring-barrel or arbor when the yoke is in its winding position, Figs. 3 and 4., while the pinion f meshes with one of the wheels of the dial-train when the yoke is initshands-setting position, Figs. 1 and 2.

The winding-stemkis adapted to slidelengthwise in its winding-pinion, and has a square port-ion fitting a square socket in the windingpinion.

Z represents a lever pivoted at m to the pillar-plate b, and having a notch or recess, a, at

one side ofits pivot, receiving a flange, 0, on

an extension or tip, k, secured to the windingstem k. At the opposite side of the lever Z is an extension, which is provided with two edges, 2 3, adapted to bear alternately against a stud affixed to the yoke, the edge 3 bearing against said stud when the yoke is in its handssetting position, and the cdge2 when the yoke is in its winding position.

Then the yoke is in its winding position,the winding-stem is moved inwardly,and the stud q bears upon the edge 2, as shown in Fig. 4,the yoke being normally held in said position by the usual spring, r. When the Winding-stem is moved outwardly, the engagement of the flange 0 with the lever Z causes the latter to turn on its pivot to the position shown in Fig. 2, and thereby move the yoke to its hands-setting position, and prevents the spring 1' from moving the yoke back to its normal position until released by the inward movement of the winding-stem.

The tip it, having the flange 0, is provided at one end with a threaded socket, into which the reduced end of the winding-stem is screwed after the tip has been inserted in the socket s .9, prepared for it in the pillar and top plates of the movement. (See Fig. 5.) The tip is prevented from rotating when the winding-stem is being screwed into it by ascrew, t, inserted in the top plate, a, said screw being turned until it bears firmly against the flange 0, so as to hold the top rigidly. After the winding stein has been screwed in the screw t is loosened, and the windingstem and tip are thus enabled to rotate and move freely lengthwise.

It will be seen that the described devices constituting my improvement are simple, efficient, and durable.

Other equally obvious modifications may be made without departing from the spirit of my invention.

I claim- The'oombination, with the hand setting and winding mechanism, of a spring-pressed yoke having a stud, q, the pinions carried by said DUANE H. CHURCH.
