To @ZZ wtontzft may concorre:

Be it known that l, Lne Anni?, a citizen of the United States, residing at Columbus, in the county ot' Franklin and State of Ohio, have invented certain new and useful Improvements in Stem Winding and Setting Vatches; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apportains to make and use the same.

My invention relates to stem-winding and stenrsetting watches, and has for its object to simplify and perfect the construction and arrangement of the parts oi' the ordinary mechanisms, in which an outward pull of the stem and its connections throws the winding mechanism out ol' gear and the setting mechanism into gear, and in which a reverse or inward movement of said stem and its connections restores the winding mechanism to normal position and disconnects the setting mechanism, and it consists in the construction, arrangement, and combination of parts, hereinafter disclosed in the description and claims.

ln the accompanying drawings, forming part of this specification, and wherein the same reference-letters indicate the same parts, Figure 'l representan vertical side elevation oi' a watch and a portieri of its movement with my improvements applied thereto, parts being in section and the dial removed, and showing the Breguet clutch in position for winding and the setting or intcrn'iediate wheels out of gear with the dial-wheels; Fig. 2, a similar view of the same parts with the mechanism in position for setting the hands; Fig. 3, a horizontal section through the setting-lever, showing the pin thereon resting in the annular groove in the stem and the device for adjusting the same into and out of said groove, Fig. il, a similar view' with the setting-lever disconnected from the stem, or with the pin adjusted out of the annular groove to permit of the removal of .said stem; Figs. 5, G, and 7, detail side elevations, respectively, ot' the interiorly-squared sleeve, the potence or crutch, and the clutchpinions, and Fig. f3, a side elevation of the stem and a vertical section of the pusher or crown devices for operating the same, the crown de* vices being shown as moved down for opening the ease, and the clutch-pinions, the` sleeve,

and the step and crutch being shown in sec tion.

ln the drawings, A represents a pivoted set ting-lever, which is adapted to he raised by means of a screw-pivot, a, provided with an annular shoulder or collar, a', as shown in Figs. 3 and rt, so as to permit thc stem A to be raised from the watch-movement and lowered back into normal position again. To assist in et'- fecting this result, the end ofthe upper or horizontal arm of said lever is provided with a pin, a, which fits in an annular groove, d", formed in said stem.

The ordinary Breguet clutelrpinions, B B', are loosely mounted upon a sleeve, B2, formed with a square exterior and interior and provided at its upper end with a bevel or angle wheel, Bi, which communicates motion to the winding mechanism, which is not shown in the drawings. This sleeve B2 is supported at its lower end upon a potence or crutch, C, Figs. G, 7, and 8, iirmly securedto the pillar-plate and having a step or extensionjp, itted in the lower end of said sleeve, as indicated by dotted lines in Fig. 7 and in full lines in Fig. 8. This sleeve turns upon the step, and the lower end of the stem is journaled in said step, as clearly shown in Fig. 8. These parts are so con.- structed and arranged, as shown in detail in Figs. 5, 6, and 7, as to keep the clutch-pinions in tixed position during the removal and insertion ot' the stem.

.D represents a settingbar, which is pivoted at one end at d and carries at its opposite end the setting-wheels E E. lt is also provided near its middle with an elongated slot, d', through which a screw, d2, passes. This screw not only holds the setting-bar in proper position, but acts as a stop to limit and regulate the depth of mesh of the cogs or teeth on the setting-wheels l] E and the minute-wheel F when the parts are in position for setting the hands.

The setting-bar D is provided at its inner end with an upwardly and horizontally extending projection, di, which engages in the ordinary annular groove of the sliding clutch. A spring, G, holds this projection against the clutch-pinion B and forces the same with a yielding pressure into mesh with the bevel or angle pinion IOO H represents an ordinary ring or band attached to a hollow pendant, H', in the usual manner, vsaid pendant projecting upwardly into an annular recess, h, in the pusher or of the sleeve I', for the purpose hereinafter' stated. The upper end of the windinglstem is reducedand formed into ascrew, upon which is placed a nut, i, for holding the sleeve I from undue upward movement.

In open and hunting case watches the setting-lever A is formed with a projection or point, of proper length to just touch the head j of the case-spring J when the case is closed, so that in the event of the watch being pulled out of the pocket by the crown the strain incident thereto can have no effect upon the setting mechanism, as said point am projects against the spring head and prevents such an effect; but when the case is sprung open the head of the case-spring will move outwardlya sufficient distance to permit the pulling action upon the crown to move the settinglever A and setting-bar D, and thus bring into action the train of setting and minute wheels E, E', and F. Also, the action ofthe head j of the ease-spring J when the case is closed has the effect of automatically pressing upon the lpoint am of the pivoted setting-lever A, re-

leasing the latter from the spring-controlled setting-bar D and causing the parts to assu me their` normal or winding positions, thus dispensing with pulling the stem outward by hand for effecting this result.

Theaoperation of my invention, excepting as is obv1ous and thus far described, is as follows: The movement being in the case and the parts in the position shown in Fig. 1, the mainspring will be wound up by rotating the crown forward, as in the ordinary Breguet clutchwatch. By rotating the crown backward the settingwheels E and E will also be set in motion, as they are in constant gear with the clutch-pinion B, but they will have no effect on the minute or dial wheels F, as sufficient space is provided between them and said setting-wheels to allow of a slipping action between the ratchet-teeth of the clutch-piniQmB and of the anglewheel B3 during the backward rotation of said crown.- When the crown and stem are drawn outward, the setting-lever A will follow their movement, and thus be turned on its pivot a, when its lower arm will force the setting-bar D downward against the upward pressure of the spring G for a distance equal to the length of the slot d', in which the screw d2 is located, as shown in Fig. 2. The

clutch-pinionB will then be disengaged from the angle-wheel B3 and the winding-train and the setting-wheels brought into connection with the minute or dial wheels, when the crown and stem may be rotated and the hands turned in either direction. In order to remove the movement from the case, the screw-pivot a is turned, thus raising the setting-lever A and disengaging its pin a from the annular groove a' in the stem A', which can then be taken out and the movement removed. The interiorly-square sleeve B2, fitted upon the step of the potence or crutch C, keeps the clutch-pinions and angle-wheel in fixed position during this operation, as shown in Figs. 7 and 8, and also permits the stern to be reinserted without trouble in recasing the movement. In order to provide for the necessary play for actuating vthe case-spring without affecting the stem and setting mechanism the interior square portion i of the sleeve I is made shorter than the corresponding square part of the stem A, and provided with the interior shoulder, i, for contacting with theshoulder on the stem adjacentthereto. By this construction and arrangement of the parts, in connection with the nut 'i2 on the upper end ofthe stem, sufficient play is allowed said sleeve to cause it to press against the head of the casespring and permit the case to be opened when the crown is pushed inward;

also, on pulling the crown outward said sleeve will abut against the nut 'i2 and move the stem and horizontal arm of the setting-lever outward, and thus actuate the setting mechanism.

Having thus fully described the construction and arrangement or combination of the parts of my invention and its operation,what I claim as new isl. In astem winding and setting watch, the combination of the dial-wheels and the setting wheel or wheels with 'an end-pivoted settingbar carrying said setting wheel or wheels and the sliding stem and clutch-pinions for actuating said bar for throwing said setting and dial wheels into and out of mesh, substantially as and for the purpose described.

2. In a stem winding and setting watch, the combination of the dialiwheels and one or more setting-wheels with an end-pivoted setting-bar carrying said setting-wheel or wheels, and provided nearits middle with an elongated slot, a screw passing said slot and acting to limit the depth of mesh of the cogs or teeth of said vsetting and 'dial wheels, and devices for vmoving said wheels into and out of mesh, substantially as described.

3. In a stem winding and setting watch, the combination of the dial and setting wheels, the end-pivoted bar carrying said' setting-wheels and provided with an upwardly and horizon- IOO IIO

4. n a stein winding and setting watch, the

combination of the dial and setting wheels, the.

end-pivoted bar carrying said setting-wheels and provided with an upwardly and horizontally extending projection, the spring supporting thc inner end of said bar with an upward pressure, the setting-lever having a pin on its horizontal arin, the adjustable or screw pivot for said lever, and the stem fornied with an annular groove in which said pin engages, substantially as described.

5. In a stem winding and setting watch, the combination of the pillar-plate, the potence or crutch iirnily secured to said pillar-plate and provided with a step or extension, the exteriorl1 and interiorly square sleeve rigidly tted at its lower end upon said step or extension and provided at its upper end with `the anglepinion, the sliding clutch-pinions, and the stein having asquare lower portion iitting in said sleeve, the parts being so constructed and arranged as to retain said pinions in fixed position during the removal and insertion of said sten), substantially as described.

G. In a stein winding and setting watch, thc combinetion of the dial and setting wheels, the spring-controlled cnd-pivoted settingbar D, having the projection d, the stem A, the elutclr pinions, the pivoted setting-lever A, having` the projection or point a,, and the case-spring J, arranged to have its heady` in contact with said projection cd, the construction and arrangement of said projection and case-spring' being such as to prevent the outward movement of the stein when the case is closed to permit the outward movement of said Stern for setting the hands when the case is open and to automatically force said stein inward and secure the normal or winding position of the parts in closing the case, substantially as described.

7. In a stem winding and setting watch, the combination of the case having the hollow pendant, the crown provided with an interiorlythreaded tubular portion, the exteriorly-threaded sleeve formed interiorly square along its upper portion and provided with an interior shoulder, the casespring upon which the lower end of said sleeve rests, andthe stein provided with a square upper portion of greater length than the interior square portion of said sleeve and having a nut upon its upper end, whereby the necessary play for actuating the casespring and opening the case is effected without affecting the setting ineclr anisni, substantially as described.

ln testimony whereofl affix my signature in presence of two witnesses.
