MEANS FOR CONTROLLING THE WINDING AND SETTING MEANS OF WATCH MOVEMENTS Filed Oct. 9, 1928 INVENTOIR dorm GRAFFEN BERGER- ATYORN EY Patented Apr. 1 4, 1931 UNITED STATES PATENT, OFFICE JOHN G. BERGER, 0F FORT WORTH, TEXAS MEANS FOR CONTBOLLING THE WINDING AND SETTING MEANS OF WATCH MOVEMENTS Application filed October 9, 1928. Serial No. 311,270.

. My invention relates to watch case winding and setting systems for watch movements having sleeve systems for pulling and pushing the crown; and the object is to provide 5 simple devices for eliminating sleeves and tubes, and does away with threading in cases in watches in use at the present time. One advantage is that the necks can be made shorter or the necks may be dispensed with entirely. The sleeves heretofore in use have been fragile and have caused much trouble and expense and waste of time. Other objects and advanta es will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a view of a watch with the cover removed, showing the improvements in the setting position;

Fig. 2 is a view of the winding stem, winding pinion, mutt-wheel, devising or controlling pin for setting and winding purposes in winding position.

Fig. 3 is a diametrical section of a watch case, showing the controlling pin in winding position.

Fig. 4 is a view showing the stem and controlling pin in setting position.

Fig. 5 is a broken section of the watch lid, showing the curved cam groove for the controlling pin.

Fi 6 is a broken interior view of the lid, showing the curved or cam groove, and Fig. 7 is a broken section of the lid, on the line 7 7 of Fig. 6.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show a case of ordinary type having a casing 1 and a lid 2 and back lid 3. The casing 1 has an opening 4 for the operation of the stem 5. A seat 6 is formed in the pendant 7 of the casing 1 for the crown 8. A sleeve guide'9 is formed on the casing 1 for the crown 8. The stem 5 is screwed into the crown 8. A winding pinion 10 is loose- 1y mounted on the stem 5 and a mufi wheel.

11 is rigid with the stem 5. The winding pinion 10 has teeth on the end thereof which are ada ted to mesh with teeth 13 on the end of t e muff wheel 11 for the purpose of setting the watch. The muff-wheel 11 has teeth 15 on the other end for meshing with a gear wheel 16 of the setting mechanism. The stem 5 is provided with a friction drive. A bevel wheel 17 is rigid therewith and a controlling pin 18 carries a. bevel wheel 19 rigid therewith which is adapted to engage with the wheel 17 The controlling pin 18 is actuated by the lid 2. The lid 2 has a curved groove 20 which serves as a cam. The lid 2 is screwed on the casing 1. The members 17 and 19 bring the parts to winding position by turning the lid 2 until the groove 20 is turned away from the pin 18. The pin 18 will ride on the fiat face of the lid and this will force the pin 18 to the position shown in Fig. 3. The teeth 13 will be forced axially on the stem 5 so that they will mesh with the teeth 12 of the muff-wheel 10. The watch can then be wound by turning the crown 8. If the lid 2 is then turned, the groove 20 will receive the pin 18 and the friction shift will then come to the position shown in Figs. 1 and 4. The teeth 13 will in this action leave the teeth 12. The watch can then be set by turning the crown 8.

The controllin means may be used with the front lid as shown or the means may be used in the back lid and the improvements can be used in screw cases and snap cases. The assembly of this device is accomplished by first inserting the pin 18 in the case so that the curved wheel or shoulder 19 will keep the pin 18 from passing through the case when the lid 2 is open.

What I claim, is,

1. Winding and setting means for watch movements having a stem provided with the usual winding and muff wheels, a controlling pin mounted in the watch casing at right angles to said stem, bevel engaging members rigid with said pin and stem for actuating said stem, and means for actuating said pin by the lid of the watch consisting of the lid for the watch having a flat rim and a curved groove therein.

2. Winding and setting means for Watches comprising a stem having the usual Winding and mufl-Wheels, a bevel Wheel rigid With said stem, a controlling pin mounted in the Watch casing at right angles to said stem and provided with a beveled member for engaging said bevel Wheel, and means for actuating said control pin and bevel member and wheelfor positioning said muff-Wheel.

Intestimony whereof, I set my hand this 7 6th day of October, 1928.
