WATCH.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed March 11, 1915. Serial No. 13,593.

To all whom it may concern Be it known that I, CHARLES L. DEPOL- LIER, a citizen of the United States, residing in the borough of Brooklyn of the city of New York, in the county of Kings, in the State of New York, have invented certain new and useful Improvements in atches, of which the following is a specificat-ion, reference being had to the accompanying drawing, forming a part hereof.

This invention relates particularly to stem-winding and stem-setting watches. It is well known that retail dealers in watches receive many complaints concerning ladies watches to the efiect that the watch will not run and must be replaced by a good one. The cause of the complaint is usually that the watch has not been wound and has stopped because it has run down. In the case of wrist watches and other miniature watches the failure to wind the watch is often-times to be attributed justly to the necessarily small size of the crown which must be rolled between the fingers in order to wind the watch. When this crown is very small and is partly inolosed by the bow it is often-times very di'flicult to grasp it so that it is rotated with certainty.

It is the object of this invention to overcome this difficulty and the object is accomplished by making the bow itself, which is easily grasped, rotatable for the purpose of winding the watch.

It would be undesirable to let the bow be pulled out for the purpose of setting the hands of a watch and provision is therefore made whereby the pulling out of a central arbor and crown efl'ects the necessary coupling between the bow and the setting device to permit the setting to be accomplished by rotation of the bow.

The invention will be more fully described hereinafter with reference to the accompanying drawing in which it is illustrated and in which Figure 1 is a detail view, partly in section, showing so much of a watch as is necessary to enable the application of the invention thereof to be understood. Fig. 2 is a detail view in section on the plane indicated by the line 22 of Fig. 1.

The watch-case center a is bored to receive loosely, so that it shall be capable of rotation, a radial sleeve 1) which is provided at its inner end with a flange or external shoulder b to bear against the inner surface of the center around the hole. The sleeve 1) projects beyond the center and has tightly secured thereto, outside of the center, a ring or collar 0 to which the usual bow cl is secured, preferably by pivot screws d as shown. Within the sleeve 6 and near its outer end is tightly secured a sleeve 6 which is formed with an axial, polygonal hole 6', in which fits freely, as it has to be capable of endwise movement, the arbor f which has its upper part polygonal in cross section to conform to the hole 6.

On the outer end of the arbor f is secured the crown g which forms a suitable finish for the end of the arbor and also furnishes a hold by which the arbor 7 may be pulled out to a limited extent for the purpose of setting the watch. The lower or inner end of the arbor 7 is guided in a suitable bearing and is adapted as usual for engagement with the winding and setting devices, which it is not necessary to show and describe, since they may be of any usual or suitable construction. Spring jaws h of the usual character are provided to cooperate as usual with a beveled portion of the arbor f for the purpose of retaining it yieldingly in one position or the other.

It will now be seen that the bow d is at all times connected operatively with the arbor 7 so that the arbor may be rotated by grasping the bow, whether the arbor is in its inner position for winding the watch or in its outer position for setting the watch, and that while the bow is not movable radially with respect to the watch, the arbor f may be moved radially for the purpose of effecting operative engagement with the winding mechanism or the setting mechanism as may be desired.

It will be obvious that changes in details of construction and arrangement may be made to suit different conditions of use and that the invention, therefore, is not limited to the particular details shown and described herein.

I claim as my invention 1. In a watch, the combination of a watchcase center, a sleeve passing radially through said watch-case center and rotatable therein, a bow secured externally to the outer end of said sleeve, and a winding arbor mounted axially within said sleeve and operatvely engaged thereby.

2. In a watch, the combination of awatchcase center, a sleeve passing radially through said Watch-case center and rotatable therein, said sleeve having at its inner end an eX ternal flange or shoulder, a boW secured externally to the outer end of said sleeve, and a Winding arbor mounted axially within said sleeve and operatively engaged thereby.

3. In a Watch, the combination of a Watchcase center, a sleeve passing radially through said Watch-case center and rotatable therein, a bow secured externally to the outer end of said sleeve, and a Winding arbor radially movable Within said sleeve but operatively engaged thereby so as to be rotated therewith.

4.. In a Watch, the combination of a Watchcase center, a sleeve passing radially through said Watch-case center and rotatable therein, a bow secured externally to the outer end of said sleeve, a second sleeve secured Within the first named sleeve and having a polygonal hole therethrough and a Winding arbor having its outer portion polygonal in crosssection to conform to said hole so as to be movable radially therethrough but to be ro tated therewith.

5. In. a Watch, the combination of a Watchcase center, a sleeve passing radially through said watclrcase center and rotatable therein, a bow secured externally to the outer end of said sleeve, a Winding arbor mounted aXially within said sleeve and operatively engaged thereby and movable axially therein and a crown secured to said arbor outside of the end of said sleeve.

This specification signed and witnessed this third day of March, A. D., 1915.

CHARLES L. DEPOLLIER.
