may concern.-

that I, ALFRED BARTON, of Boston, county of Suffolk, State of, Massach-u setts, have invented an Improvement in Stem Winding and SettingMechanism forWatches, of which the following description, in con-- mention withthe accompanying drawings, is

a specification, representing like parts.

This invention'relates to stem winding and setting m'echanismsfor watches. One of the objects of this invention is to simplify and improve the construction and operation of'the'mechanism, and anothorobject of. the invention is to provide .mechan ism, the winding and setting connection or clutch member of which, when the movement is removed fromithe watch-case, shall-beout of engagementwith the setting traimas dis.

tinguished from any mechanismheretofore constructed in whichthe clutch member or the movement is out-0t its connection, when case, is in engagement with the setting train.

1' Other featuresot this invention 'will be hereinafter described and set forth in the In the drawings,-Figure1 represents in face view a sufficient portion of a watch-case its movement to enable this invention to be and c constituting a understood; Fig. 2, an enlarged vertical section of apart of the same taken on the dotted line 23-00; Fig. 3, a view showing the parts in the position they will assume when the movement is removed from the case. Fig. 4:

Fig. 3, showing the clutch p -isa-'s imilar view to member in engagement with the setting train; and Fig. 5, a modification to be described.

Referring to the drawings, the watch-case A, pendant B, bowO, the crown D with its attached long stem at longitudinally movable within the pendant and provided with suitable devices therein to retain it in either its in or out position, are and maybe of usual or desired construction common to watches of the present time.

The pillar-plate a,-of the watch movement, together with the wheels I), b, constituting a part of the setting train, and the wheels 0, 0 part of the winding train, are and may be of usual construction and arrangement;

like letters on the drawings 7 .the' stemis squared, as

and

"lever m having a Mounted in suitable bearings at the under side of the pillar-plate is the longitudinally movable short or inner stern e socketed at its upper end, see Fig. 2, to receive the squared end at of the long stem d, said short-stem e at its socketed end being provided with an enlarged head e, grooved, as at 2 for a pur-.

pose to be described. Near its lower, end at 6?, or otherwise adapted to'receive the clutch member f which in the present construction constitutesthe winding and setting connection, said clutch member being rotatable with but longitudinally movablewn the said short stem, said clutch member atitslowe-r end'being toothed as at f or Otherwiseadapted to engage with and to rotate the wheel I) of .thesetting train, said clutch member at its opposite or upper end being, in the present instance, ratchet toothed to engage the ratchet teeth g on the pinion gloosely'journaled upon the short winding traimsaid pinion 9 ,thereby constituting a parhof the winding train. The pinion g is retained in position at one side by the bridge pipes a oi the'pillar-platein which the short stem e at its opposite side by the winding wheel c with which it is in mesh. I g

The clutch member f is grooved, as at f to receive the free end of the clutch operating idly secured at "m to the pillar-plate, said operating lever being T-shaped, and at its uper end socketed to receive the rounded-end n of the clutch actuating lever n pivoted at M, and with its free endn lying in the groove 6 in the head of the short stem. e.

The resiliency of the tail m of the operat ing lever m tends to move said operating lever and the clutch'inember f into its lowermost position in engagementor mesh with the wheel I) of the setting train, such movement of the operating lever and clutch mem her also acting through the actuating lever n to throw the short stem e into its elevated position, such movement of the said short stem, however, being resisted by the crown D and its longstem 0. within the pendant, the usual devices within the pendant being suiiicient to has one of its bearings, and v stem 6 and in mesh with the wheel a oi the resilient tail portion m rigz o commonly constructed, when-the watch moveposition.
