IMPROVEMENT IN WINDING AND SETTING WATCHES.

Specification forming part of Letters Patent No. 40,568. dated November 10, 1563.

To aZZ whom it may concern.-

Be it known that I, CHARLES EUGENE LAEDERIOH, of St. lmier, Canton Berne, Republic of Switzerland, have invented an improved arrangement of watches, for allowing the winding up and the setting of the hands of the same to take place by the knob of the pendant 5 and I do hereby declare that the followingis a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

These improvements in watches relate to a mechanical arrangement, which in the manufacture of watches may be applied to the movement of the same, with the object of allowing the winding up and the setting of the hands of the watch to take place by the knob of the pendant, through a sliding stem and pinion, instead of by a separate watch-key, thus forming a new and simpler description of remontoir watch as the watches of that class hitherto manufactured.

In the annexed drawings, Figure 1 shows 4 a view of the inside of a watch with the dialplate removed, in which those parts only are represented as constitute the arrangement called remontoir, forming the object of my invention. Fig. 2 shows another view of some of these parts. Fig. 3 is a side view of the same, and Figs. 4 and 5 show views of separate parts.

The same letters of reference show corresponding parts in the various figures.

a is the pallet or pillar-plate of the watch, of which latter I) is the ring and c the knob of the pendant c, which knob 0 is fixed to the end of a spindle, d, passing through a projecting boss, 6, and which may glide forward and backward in this pendant c. To the other end of the spindle (I is fixed a pinion, f, called the remontoir pinion.

g g is a depression provided in the said spindle d, for giving passage to a small wheel, h, (represented separately in Fig. 5,) which wheel h forms part of the ratchet wheel 1', and is situated in the inside of a depression or cavity, j, provided in the palletplate a, (see Fig. 2,) round the boss or projection e. The

wheel 1 is consequently situated in the position shown in Fig. 1, and its motion is steadied by a disk, It, fixed in position by means of two screws, Z and Z. The wheel iis in gear with a ratchet-wheel, m, fitted on the axis of the barrel.

a is a gliding stop, the free end a of which, when the stop is pushed forward, takes into the neck 0 of the spindle (l, for permitting to keep the remontoir pinion f, when required, in gear with the wheel h, in order to allow of, by turning the knob c of the pendant, winding up the watch.

In order to allow the setting of the hands to take place by means of the same knob, the 1ninute-wheel p is situated on the contirmatia, and in the axis of the spindle d. This wheel 19 is of eighteen teeth and drives a six-tooth pinion, 1), moving the minute-hand, and the same has also an eight-tooth pinion, p driving a thirtytwo-tooth-wheel for the hour-hand.

The pinion p or minute-wheel, of which F ig. 4 represents a separate side view, is arranged in such manner that the side gear becomes a top gear when the pinion f is put in gear with the cogs or teeth at the lower part of this pinion or wheel 1).

In Fig. 1 either the teeth of the wheel h or the teeth or cogs p of the pinion or wheel 12 may, according as required, either the one or the other, be put in gear with the remontoir pinionf. Thus, if it he wished to wind up the watch the spindle d is by means of the stop a fixed in the position shown in Fig. 1, whereas for setting the hands the stop a is drawn back and the spindle (I pushed forward, so as to cause the pinion f to set free the wheel h, and be broughtin gear with the lower c0gs,p of the minute-wheel p. The setting of the hands being finished, the spindle at is drawn back in the position required for winding up viz., shown in Fig. 1.

From what has been said, it will be obvious that my improved remontoir arrangement offers the following conspicuous points, first, that the winding up by the wheels '5 and m requires but very little turning of the spindle d secondly, that for setting the watch-hands the operator requires the use of but one of his hands thirdly, that the arrangement may be applied to any description of watches, as well above as underneath the pallet or pillarplate of the same.

Having thus described the nature of my invention and the manner in which the same sition for winding the watch, its other posi tion for moving the hands being regulated by the end of its movement, thus enabling the user to operate the parts by one hand only, substantially as described and illustrated by the annexed drawings.
