STEM WINDING AND SETTlNG MECHANlSM FOR WATCHES.

.LPECFICATXQN 'forming part of Letters Patent No. 340,850, dated Ap1i12'7, 1886.

Application filed November 9, 1895. Serial No. 152,218. (No model.)

To @ZZ nftonz/ it may concern.-

Beit known that l, CHARLES V. VoERD, of Valtham, in the county of Middlesex and State of Massachusetts, have invented certain `new and useful Improvements in Stem-linding ,Vatches, of which the following is a l'ull, clear, and exact description.

The stem winding and settingmechanism of this invention consists in substance ol" an arbor or spindle to which the stem or pendant of the watch-case is detachably connected, and which is capable ol'sliding` in its bearings, and is provided with a pinion-wheel to engage with the setting mechanism of the watch and a loose gear-wheel to engage with the winding` mechanism of the watch, and which is adapted to be clutched with acl arching-collar attached to the arbor, in combination with a spring adapted to bear upon the arbor, and all in such manner that the arbor in its normal position is in connection with the winding mechanism, and to place it into connection with the setting mechanism requires to be drawn outwardly. rlhe spring in one ol its bearings on the arbor holds it in its normal position-that is, with the arbor engaged with the winding mechanism-and in its other bearing upon the arbor it holds the arbor in connection with the setting mechanism until relieved by pushing the arbor inwardly.

In the accompanying plate of drawings the present invention is illustrated, and Figure l is a central vertical section through the pillar and top plates of awatch-movement and other parts thereof necessary to illustrate the connection of the mechanism of this invention therewith; andlflig isa plan view ofthe mechanism of this invention, and showing in dotted lines those portions of the train of gears making up the watch-movement, which malle more particularly direct connection therewith.

In the drawings, A represents the pillarplate; l, the top plate, G, the center-wheel; D, the hour-wheel; E, the cannon-pinion; F, the crown-wheel; G, an intermediate wheel connecting crown-wheel F with the winding-barrel, all as usual in watch-movements, and therefore needing no particular description herein.

H is an arbor or spindlelocatcd between the pillar and top plate, A B, and extending in a parallel direction therewith, turning at its end portionsin bearing-blocks J ofthe pillarplate. rlhis arbor or spindle is the winding` and setting arbor of the watch-movement, and at its outer end it has the stem or pendant K of the watch-case screwed into the same, thus allowing` said pendant to be detached at pleasure from the winding-arbor by unscrewing it therefrom, the arbor at such time being fastened against movement by turning up a setscrew, li, against it. IThis set-screw passes loosely through the top plate and screws into one ofthe beari iig-blocks .l of the winding and setting arbor. rlhe winding and setting arbor, with such set-screw loosened or released in its bearing thereon, is free to be moved lengthwise inwardly and outwardly through its bearing-blocks wi thin a determined or certain limit. rllhis arbor ll, at its inner end has abevel piuion-wheel, lil, and near its outer end a ratchettoothed clutching-collar, N, both attached to it, and inside of the clutching-collarisabevel gear-wheel, O, free to turn upon it, and which is at all times in engagement with the bevelgear of' the crown wheel F. \Vith the arbor ll. at the limit of its outward movement ils clutching-collar N is out of enga-gement with a similar and eorrespondiiig-shaped clutching-collar, R, forming a part of the loose bevel gear-wheel O, connected with the crown-wheel F, as described, and with the bor at the limit of its inward movement, its cl utching-collar is engaged with the clutchingcollar ol" said bevel gear-wheel, and thus the arbor is connected with the winding mechanism ol' the watch, so that then on being turned in the proper direction the watch can be wound.

ln the winding position of the arbor above described the bevel-pinion M at the-inner end of the arbor is out of connection with the bevel crown-wheel S, that connects by a pinion-wheel, T, with the cannon-pinion E of the movement; but this bevel-pinion M, with the arbor at the limit of its outward movement, (in which position of the arbor its clutchingcollar is out of engagement with the clutchingcollar ofthe bevel-gearO ofthe winding meehanism ol the movemena) is in engagement IOO scribed, while the arbor is being turned to set with the bevel crown-wheel S, connected with the cannon-pinion E, and thus the arbor is adapted for the setting of the hands.

The normal position of the Winding and setting arbor is, with its clutching-collar engaged with the clutching-collar of its loose bevel-gear connected with the winding mechanism, as has been described, and the winding-arbor is held in this position by means of a bent'spring, U, conned at one end, and at its free end bearing upon the circumferential conical-shaped face V of the arbor.

To disconnect the arbor from the winding movement, the arbor is pulled out, and in this movement of the arbor the spring U, bearing thereon, as has been described, then comes to a bearing upon another circumferential conical-shaped surface, W, ofthe arbor, and back of, or, in other words, between the conical-shaped bearing-surface V, before referred to, and the bevel-pinion M on the arbor, and through which to set the hands when in proper connection. This bearing of the spring U serves to retain the bevel-pinion M in connection with the setting mechanism, as has been dethe hands; but by pushing in the arbor to disconnect it from the setting mechanism of the watch-movement, the bearing of the spring on the arbor is changed to the conical bearingsurface V, and thus the arbor is held in connection with the winding mechanism, which is its normal position, as before stated.

lf the arbor in its normal position is turned in the wrong direction, as it can slide in its bearings, its clutchingcollar passes freely over the clutchingcollar connected with the winding mechanism, and thus no effect is produced on such mechanism; but this movement, however, of the arbor is not suficient to put it into engagement with the setting mechanism.

It is apparent vfrom this description that as the winding and setting arbor requires to be pulled out to connect it with the setting mechanism of the movement, there is no liability of any accidental disturbance of the position of the hands of the watch from any pressure upon or contact with the stem or pendant, detachably connected to'the arbor, as described. Again,it is apparent that simply by a removal of the pendantlor stem from the winding and setting arbor,the watch-movement is then free to be removed from thecase,in so far as its previous connection with the stem or pendant of the watch operated to prevent the same.

The spring U and its bearings of the arbor may be dispensed with, but it is preferable to employ them. I

Having thus described my invention, I claimp 1. The combination, with a watch-movement, of a longitudinally sliding and turning arbor, H K, made in attachable and detachable parts, to permit, detached, the then removal of the movement from its case, and provided with two wheels, M O, one, M, immovable thereon, to engage the hand-setting train for setting the hands, and the other, 0, loose, but otherwise confined against movement thereon, to engage the winding-train for winding the Watch, and a clutch, N R, in two parts, one, N, immovable, and the other, R, loose thereon, and of its said loose Wheel O, substantially as described, and operating together as specified.

2. The combinatiomwith a watch-movement, of a longitudinally sliding and turning arbor, H K, made in attachable and detachable parts,

to permit, detached, the then removal of themovement from its case, and provided with two wheels, M O, one, M, immovable thereon, to engage the hand-setting train for setting the hands, and the other, 0, loose but other- Wise confined against movement thereon, to engage the ywinding-train for winding the watch, and a clutch, N R, in two parts, one, N, immovable, and the other, R, loose thereon, and of its said loose wheel O, and also provided with two peripheral bearing-surfaces',V, running at opposite angles to its axis, and of a spring-arm, U, confined -at one end, and at its other and free end having abearing upon said bearing-surfaces of the arbor to prevent the accidental sliding of the arbor, substantially as described,and operating together as specified.

'In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CHAS. V. VOERD.
