S'iEM-WlNDlNG WATCH.

SPECIFICATION formingpart of Letters Patent No. 250,148, dated November Application filed March 21,1881. (Model-l To all whom it may concern:

Be it known that I, JOSEPH W. HURD, residing at Rockford, in the county of Winnebago and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Stem-Winding Watches, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a view showing the pillar-plate and parts connected therewith, the small wheel which acts in setting the hands being disen gaged-from the train. Fig.2 is a similarview, showing such setting-wheel engaged with the train; Fig. 3 is an edge view. The remain-- ing figures, from 4. to 10, inclusive, are details.

The object at my invention is 'to provide simple and efficient means for setting the hands of a watch; and this object I accomplish by the mechanism illustrated in the accompanying drawings, which I will now proceed to describe in detail, afterward specifi: out the improvements in the In the drawings, A represents the pillar- .plate. a is a lever orbar pivoted to the pillar-plate at b,- but between it and'such plate there is room for wheels.

c is a small wheel upon the under side and inner end of the lever a.

d is a small wheel upon the pivot of the lever a, which wheel dcngagcs with the wheel 0.

e is a yoke pivoted upon the screw f.

a his a wheel at one end of this yoke, which Wheel engages with the wheel (I at all times. It also engages with the winding-wheel y when the parts are in the position shown in Fig. 1.

r is a lever which operates the yoke e. i is a spring.

j is a small plate, having a hub, is, on the top thereof, and a flange, l, at right angles to such plate.

m is the winding-stem, which carries a pinion, n. The stem is inserted iii-a hole in the flange l and held therein by a screw on the inside of the flange, but so that the stem can rotateo is a. wheel which is placed upon the hub 70 on the plate j. The yoke e rests on the top of this hub. The plate j and yoke e are both held in place by the screw f, and the'wheel 0 is between-the platej and yoke e, and engages with the wheel it, which is carried by the yoke e.

In use the parts will ordinarily be in the position shown in Fig. 1, ready for winding, the wheel It being engaged with the windingwheel 9. In this position the hands cannot be set, because the wheel a the train.

By means of the lever r 0 can be made to act upon the lever or bar a, bringing the parts'into the position showirin is disengaged from one end of the yoke I Fig. 2, in which the wheel 0 will be engaged with the wheel 1;, and by turning the stem at the bands can be set. r to its former position the action of the spring i will disengage the wheel 0 from o and cause the wheel h to engage with the winding-wheel g. The plate j, with its hub and flange, furnish a very compact device, having two bearings, one for the pinion n in. the flange, the other being the hub'k, which receives the wheel 0.

I do not limit myself to the exact devices shown for operating the lover or arm a, as the same may be modified, both .as 136 form and arrangement.

The wheel 21 engages with the cannon-pinion, which is not shown in the drawings.

What I claim as new, and desire to secure by Letters Patent, is as follows: Y

l. In a stem-winding watch, the combination oi the pivoted swinging lever a, provided with the wheels (1 and c, which engage each other, with the wheels 1) andg and the pivoted oscillating wheels h, engaging the wheel d on the swinging lever, said members being organized for operation substantially as and for the purpose described. v

2. The plate j, provided with ahub, k, to re ceive the crown-wheel 0, and a flange, 1, form-' ing a bearing for the winding pinion or stem of a stem-winding watch, substantially as and for the purposes specified.
