J. BAGHNER. STEM WINDING AND SETTING WATCH.
Patented Oct. 18, 1887.

JOSEPH BACHNER, OF CHICAGO, ILLINOIS.
STEM WINDING AND SETTING WATCH.
SPECIFICATION forming part of Letters Patent No. 371,539, dated October 18, 1887.
Application filed November 17, 1886. Serial No. 219,126. (No model.)
To all whom it may concern.-
Be it known that I, J OSEPH BACHNER, a citizen of the United States, residing in Chicago, in Cook county, in the State of Illinois, have invented certain new and useful Improvements in Stem inding Watches, of which the following is a specification.
This invention relates to the stem winding and setting mechanism in that class of watches and clocks in which the change from the winding to the setting gear is effected by a movement of the stem, and its object is to simplify the mechanism employed.
Prior to myinvention the devices for changing from the setting to the winding trains have been complicated, expensive to manufacture, and liable to get out of order. Frequently when a party went to wind his watch the parts would be out of order and the hands would be turned instead, so that he could not depend on his watch for the correct time. By my invention all this trouble is obviated, the mechanism is simple,it is comparatively cheap to manufacture, it does not get out of order, and it is reliable in use.
In carrying out my invention I make the stem longitudinally movable, the limit of its movement in one direction being the winding position, and the limit of its movement in the other direction being the setting position. I also provide the stem with a spring, which constantly tends to hold it inward toward the interior of the watch. On the stem, near its inner end, I place a gear,which in one position of the stem meshes with the winding-train and in the other position with the settingtrain. On the outer end of the stem is the ordinary winding-cap. I arrange the winding mechanism upon one side of the watch-movement and the setting mechanism upon the opposite side, and make the pinion of the settingtrain, which meshes with the stem gear, capable of lateral movement, so as to be thrown in and out of engagement with the stem'gear The corresponding pinion of the winding-train is not capable of lateral movement,but is fixed. Upon the inner end of the arbor I form a cone. This cone impinges upon a prolonged hub or sleeve on the movable pinion of the settingtrain, and as the stem is pushed in this cone forces the pinion outward out of mesh with the stem-gear, thus permitting the stem-gear to advance and, engage with the windingpinion.
The accompanying' drawings represent an embodiment of my invention such as above described. 7
In the drawings, Figure 1 is a longitudinal section of so much of a watch-movement as contains my invention, showing the parts in position for winding. Fig. 2 is a similar section showing the parts in position for setting. Fig. 8 is a side view of the stem with its gear and conical end. Fig. 4 is a side view of the laterally-movable setting-pinion.
In the drawings, A is part of the stem of the case of a time-piece.
B is a spring-chamber formed therein.
b is a shell screwed onto the stem A, so as to form the chamber B.
G O are portions of the side plates of the movement.
D is the winding and setting stem.
E is the ordinary finger-cap, secured to the stem by the screw 6.
F is the spring, which constantly tends to push the stem D to the interior of the watch.
G is the gear on stem D.
H is the pinion of the setting-train, which meshes with stem-gear G.
I is the arbor on which pinion H revolves.
K is the bridge over pinion H.
L is a spring between H and K, which forces pinion H constantly inward.
h is the hub or sleeve on pinion H.
M is the conical end on stem D, which impinges against h.
P is the pinion of the winding mechanism, which meshes with G.
Q is the arbor on which P is mounted.
In operation, the parts being in the position shown in Fig. 1, if it be desired to set the time-piece, the stem is drawn out by means of cap E, and spring L forces pinion H inward into engagement with G, as shown in Fig. 2, and the hands may be turned by revolving cap E. 1f,now,it be desired to wind the timepiece, the stem D is pushed in,the cone M,acting on h, forces pinion H, outward out of the way, and gear Genters into engagement with pinion P.
It will be obvious that the wheel H maybe mounted on a solid pin and the sleeve h be 2. The combination of stem D, gear G, cone firmly secured in the plate 0, so that it forms M, pinion H, and sleeve 71, substantially as set a guide for said solid pin, and the cone M will forth. 15 then act on the end of the pin. 3.
