STEM WINDIG AND SETTING MECHANISM.

SPECIFICATION forming part of Letters :Patent No. 468,204, dated February 2, 1892.

Application filed April 14,1891. Serial No. 388,856. (No model.)

' ant-setting attachment for watches, and has for its object to provide a winding-pinion capable of both a rotary and end movement and so constructed as to remain in gear withthe crown-wheel in any position; also, to provide a means whereby the winding stem or arbor may be expeditiously and conveniently attached to the winding-pinion and t-o so construct the entire mechanism that the pendant-setting is operated independent of any attachment in the case and can be attached to any ordinary winding stem or arbor, such as commonly used in stem-winding watchcases.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,` and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciication, in which similar Iigures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the front plate of a movement illustrating the application of the invention and showing 'the winding-pinion in a position to cause movement of the winding-drum. Fig. 2 is a similar View to that illustrated in Fig. 1, the winding-pinion, however, being in position to cause move' ment of the hands. Fig. 3 is a vertical section taken practically on the line 3 3 of Fig. l. Fig. 4 is a vertical section taken through the winding-pinion and illustrating the attachment thereto of the winding stem or arbor. Fig. 5 is a bottom plan View of the shifting-lever, and Fig.` G is a bottom plan View of the crown-wheel.

The winding-pinion A is provided with a pivot 10 at one en d, whereby it is journaled in its seat in the movement, and in the opposite or outer end of the pinion a socket is produced, pre terably rectangular or polygonal in cross-section. Upon the outer surface of the pinion at or near its lower end longitudinal teeth 12 are formed, and at or near the center of the periphery an annular groove 13 is produced. The pinion is further provided between its groove 13 and its upper end with a threaded aperture leading into the socket and adapted for the reception of a set or binding screw 14. The socket of the pinion is adapted for the reception of the squared end 15a of the usual form of winding arbor or stem 15, and the inserted end of the stem or arbor is provided with a recess, into which the binding-screw 14 enters. Through the medium of the screw the pinion maybe revolved by turning the stem or moved endwise by manipulating the stem in that direction. The pivot of the pinion is of sufficient length to remain in its'bearing, even when the pinion is carried outward to its full extent, and consequently when the pinion is in this position it may be revolved with as much steadiness as when in its innermost position.

The'crown-Wheel 16, which meshes with the teeth of the winding-pinion, is, in addition to the usual teeth 16a, provided with peripheral horizontally-disposed teeth 17. The crownwheel is held to revolve in a spring-pressed yoke 18, pivoted at one end upon the front plate 19 of the movement, which yoke also carries a shifting pinionV 20. The shifting pinion is in constant engagement with the teeth 17 of the crown-wheel, and the regular teeth 16n of said wheel, as heretofore stated, constantly mesh with the teeth upon the winding-pinion, whether said pinion'isin its outer or in its inner position.

The shifting pinion 2O is located between a train of gearing 21, adapted to convey movement to the hand staff or spindle of the watch and the gear 22 of the winding-drum, and is in engagement either with one or the other, according to the position ot the windingpinion.

A shifting-lever 23 is pivoted upon the front plate over the yoke and engages at one end with the free extremity of the yoke, and near its opposite end the lever is provided with a pin 24, adapted topass through an aperture in the front plate of the movement and enter the groove 13 of the Winding-pinion.

.The inner position of the winding-pinion is the normal one, and' when the pinion is in this position the lever 23 bears loosely upon the yoke, as shown in Fig. 1, and the shifting pinion 2O is in engagement with the gear 22 of the winding-drum. vVhen the winding arbor or stem is drawn outward, the windingpinion is carried to its outer position, and the upper end of the lever 23 is carried with it, and the upper extremity of the lever, engaging with the ilange of the front plate, limits the outward movement of the pinion, while the innerend of the lever, which acts as a dog, forces the yoke downward and enters the recess in the yoke, holding the latter in position to cause the shifting pinion to mesh with the train of gearing 2l, whereby when the arbor l5 is revolved the hands will be turned. By pushing the arbor inward the yoke is restored to its normal position and the shifting pinion is brought in mesh with the drum-gear and the watch is in condition to be wound.

The lever illustrated at the right ot' the stem-winding mechanism constitutes no portion of the invention, and is merely intended to show that the watch can be used as a lever-set, if desired.

It-is evident that one of the main features ot the improved. pendant-setting is that it is interchangeable and can be used on either an open-face or hunting-case watch-movement without any change in the construction of its parts.

Having thus described my invention, I claim as new and desire to secure by Letters Patentf l. In a pendant setting attachment for watches, the combination, with a crow n-wheel and shitting pinion, of a winding-pinion having a rotary and endwise movement and meshing at all times with the crown-wheel, substantially as described.

2. In a pendant setting attachment for watches, the combination, with a crown-wheel and ashifting pinion meshing with the crownwheel, of a winding-pinion having a rotary and endwise movement and meshing at all times with the crown-wheel, and mechanism for moving the shifting pinion from the winding-pinion, substantially as described.

3. In a pendant-setting attachment for watches, the combination, with a crown-wheel, a pivot-ed yoke, and a shitting pinion meshing with the crown-wheel, of a winding-pinion having a rotary and endwise movement and meshing at all times with the crown-wheel, and a shifting-lever engaging the yoke and winding-pinion, substantially as and for the purpose set forth.

4. In a pendant-setting attachment for watches, the combination, with the setting and winding gear, of a pivoted yoke, a shifting pinion mounted in the yoke, a crownwheel with which the shifting pinion meshes, a winding-pinion having a rotary and endwise movement and meshing with the crownwheel at all times, and mechanism for moving the yoke by the endwise movement of the winding-pinion, substantially as described.

5. In a pendant-setting attachment for watches, a winding-pinion provided with a socket at one end', a bindin g-screw atitssocket end, a pivot at its opposite end, peripheral teeth near the trunnion, and a groove betweenthe teeth and the binding-screw, as and for the purpose set forth.

G. In a pendant-settingfor watches, the-coinbination, with a winding-pinion provided with a pivot at one end, a socket at the opposite end, peripheral teeth near the trunnion, a binding-screw at the socket end, an annular groove between the binding-screw and teeth, and a winding arbor or stem, one end of which is inserted in the pinion-socket, the said inserted end being recessed to receive the binding-screw, of a spring-pressed yoke carrying' a shifting pinion, and a shifting-1ever provided with a pin entering the groove of the winding-pinion, the said shifting-lever being in engagement with the yoke, as. and for the purpose specified.
