WINDING AND SETTING MECHANISM FOR WATCHES Filed Feb. 1'7, 1947 flaw/Z54 Mm ENTOR Patented Oct. 10, 1950 UNITED STATES PATENT OFFICE WINDING AND SETTING MECHANISM FOR WATCHES 1 Claim.
My invention relates to a winding and setting system for watches having a pull-out lever setting device; and the object is to provide a simple means for setting the watch without having to screw the bezel entirely off as is necessary on all railroad model watches in use today. With this new lever, it is only necessary to give the bezel a slight turn to the left, set the watch by the stem and turn the bezel back to the right. This can also be used to replace the push and pull stemsetting device which has always been a source of trouble on account of broken sleeves. Other objects and advantages will be fully explained in the following description and the invention more particularly pointed out in the claim.
Reference is had to the accompanying drawings which form a part of this application.
Figure 1 is a view of the watch with the dial removed showing the improvements in the winding position.
Figure 2 is a broken interior view of the screwon bezel showing the notch 10 which controls the setting lever.
Figure 3 is a broken section of the bezel showing the notch which controls the setting lever.
Figure 4 is a perspective view of the lever controlling the winding and setting of the watch.
Figure 5 is a view of the setting lever in the winding position.
Figure 6 shows the lever being engaged by the notch in the bezel. As the bezel is given a slight turn to the left, the notch pulls the lever around to the setting position.
Figure 7 shows the lever in the setting position.
Similar characters are used to indicate the same parts throughout the several views.
The drawings show a Watch of the ordinary lever-set type. A winding pinion 4 is loosely mounted on stem 3 and a clutch wheel 2 is rigid with the stem 3. The winding pinion 4 has teeth I on the end thereof which are designed to mesh with teeth on the upper end of the clutch wheel 2. The clutch wheel 2 has teeth 5 on the lower end for meshing with a gear wheel 6 of the setting wheels. Clutch lever 8 passes through a groove 2 in clutch 2. The said clutch lever has a pin ll mounted near its end. This pin is acted upon by setting lever l which fits over same.
To set the watch, the bezel I2 is given a slight turn to the left. As the notch 10 passes over the lever, said lever is pressed up into notch I0 by spring 9 as shown in Figure 6, and carried around to position shown in Figure 7, which is the setting position. The hands can then be set by turning the stem. After the hands are set, the bezel I2 is turned back to the right and tightened. This right turn pulls the lever back around to the position shown in Figure 5, which is the winding position.
What I claim is In a watch comprising a case provided with a screw bezel, a winding and setting mechanism having a stem fitted with the usual winding pinion and clutch wheel, a clutch lever having an actuating pin near one end thereof, a controlling lever pivoted on the movement and having a slot receiving said pin, said screw bezel having a notch on the inner periphery thereof and receiving the opposite end of the controlling lever within the notch, spring means biasing said controlling lever into engagement with the inner periphery of the bezel, whereby upon rotation of the bezel in opposite directions the clutch shifts between winding and setting positions.
