STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 503,517, dated August 15, 1893.

Application filed March 29, 1893. Serial No. 468,101. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. BAGLEY, a citizen of the United States, residing at Thomaston, in the county of Litchfield, and

in the State of Connecticut-,have invented certain new and useful Improvements in Stem \Vinding and Setting Watches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being IO had to the accompanying drawings,in which- Figure 1 is a perspective view, from the front, of a watch containing my improvements, the dial being removed, and the parts arranged in position for winding. Fig. 2 is a plan view 1 of the same after the stem arbor has been drawn to the outer limit of its longitudinal motion and before the setting engagement has been effected. Fig. 3 is a like view of said watch after the setting engagement has been produced. Fig. 4: is a perspective view of the watch from the rear, the back plate being removed and the parts shown as arranged when in winding engagement. Figs. 5 and G are plan views of the same, and show, respect- 2 5 ively, the positions of parts after the stemarbor has been drawn to its outer limit, and after the setting engagement has been offected. Figs. 7, 8 and 9 are, respectively, sections upon lines so, as, as so, and 00 00 of Figs.

0 1, 2, and 3, and Fig. 10 is a perspective view of the locking device and its connecting parts separated from each other.

Letters of like name and kind refer to like parts in each of the figures.

My invention relates to watches in which the entire manipulation of the winding and setting train, is effected through and by means of a stem arbor that has no positive connection with the movement, and my said inven- 0 tion consists in the means employed for preventing accidental displacement of the hands, substantially as and for the purpose hereinafter specified.

In the carrying of my invention into practice, I employ a watch movement in which there is journaled upon the front plate A, a toothed wheel B, that is in constant engagement with a pinion C, which is journaled at a right angle therewith between said plate and the back plate D, and is provided with a square axial opening 0.

\Vithin the stem or pendant e of the case center E, is journaled an arbor F which has its inner endf squared and adapted to fit into and be contained within the corresponding opening 0 of the pinion C, and, by means of suitable spring detents within said pendant, is capable not only of rotation, but of being moved longitudinalIy within certain limits, and of being locked with a yielding force at JO each limit of such longitudinal motion.

Pivoted centrally upon the axis 11 of the wheel B, is a yoke G, which has, journaled upon one end, a pinion II that is in constant mesh with said wheel, and,by the movement of said yoke in one direction, is capable of being engaged with a winding wheel I, while upon the opposite end of said yoke is journaled a second pinion K, which is, also, in mesh with said wheel, and by a movement of said yoke in an opposite direction is adapted to be engaged with one of the dial wheels L, the arrangement enabling the mainspring to be wound, or the position of the hands changed by a rotary movement of the stem arbor E. A spring M secured at one end to or upon the plate A, and at its opposite, free end engaged with a notch g in the edge of said yoke G, holds the latter with a yielding pressure, in position to cause engagement between said pinion H and winding wheel I.

Fitted into and adapted to slide longitudinally within a groove 1) in the axis 1) of the wheel B, is a bar N, which at its inner end is provided with a stud n that projects rearward through a slot a in the plate A, and has a threaded opening at which contains the threaded end 0 of a screw 0. Said screw is in a line with and extends into the axial opening 0 of the pinion C, where its end engages with the inner end f of the stem arbor F, and, by means of a spring P that is secured at one end upon the plate A, and has its opposite end in contact with said stud n, is held with a yielding force in such engage- 5 ment.

From the central portion of the outer edge of the yoke G, an arm g extends radially outward, and at its outer end has a lateral and inward curve, which forms a semi-circular notch g and immediately outside of the same, an outwardly and laterally inclining face g Within the outer end of the barN is a stud n which, when the stem arbor F is at the inner limit of its longitudinal motion is just clear of said notch g as seen in Figs. 1 and 7, and does not interfere with the free oscillation of said yoke; butwhen said stem arborhas been drawn outward,said stud is forced into engagement with said notch, as shown in Figs. 2 and 8, and acts as alock to hold said yoke in winding engagement. The object of such locking of the yoke in winding engagement is to prevent accidental displacement of the hands, should the stem arbor be accidentally drawn outward while the watch is being removed from the pocket, but when it is desired to effect setting engagement, it is only necessary that the stem arbor F be turned backward until by the back ratchet action of the pinion H upon the winding wheel I, the yoke G is turned so as to disengage the notch g from the stud of, and to bring the inclined face g into engagement with said stud, when, by the outward pressure of the spring P upon the bar N, said stud will move outward over said inclined face and operate to turn said yoke into setting engagement.

If desired, the spring P may be placed within a recess a in the outer face oi the movement plate A, and caused to engage with the projecting end of the stud 12 its action being the same in either direction.

Having thus described my invention, what I claim is 1. In a stem-winding and setting watch, the combination of the pivoted yoke which carries a portion of the stem actuated train, and is provided with the hook-shaped arm having a semi-circular notch and an inclined face, a spring that operates to hold such yoke with a yielding pressure in winding engagement, a longitudinally movable and sliding piece which is adapted to engage with such notch and inclined face, a spring that operates to hold said piece with a yielding pressure in engagement with said yoke arm, and astem arbor which has no positive connection with the movement and, bylongitudinal movements, is adapted to disengage said sliding part from and permit it to engage with said yoke arm, substantially as and for the purpose specified.

2. In combination with the stem actuated winding and setting train, the pivoted yoke provided with the hook-shaped arm, having the notch and inclined face, the longitudinally sliding part provided with the studs, the spring which operates to press such sliding part outward, and the stem arbor that is adapted to move said sliding part to and hold it at the inner limit of its longitudinal motion, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of March, 1893.
