<p>#CMT# #/CMT# A sliding pinion (20) is mounted on a winding stem (22) with a rotational axis (XX) and is fitted with a saw-like contrate toothing (30). The pinion is mobile between time-setting and winding positions, and is positioned in the winding position by a pull-out piece (24) and a lever (26). A crown wheel (32) has a rotational axis (YY) that is perpendicular to the rotational axis of the stem. The wheel is fitted with a saw-like inner toothing (34) that is meshed with the saw-like contrate toothing in the winding position to form a single direction coupling device. #CMT#USE : #/CMT# Barrel winding device for use in horology. #CMT#ADVANTAGE : #/CMT# Owing to the saw-like toothings of the sliding pinion and crown wheel, the coupling between the two transmission parts occurs in a single direction of rotation. Also, the sliding pinion is directly meshed with the crown wheel without an intermediary winding pinion so that the barrel winding device is considerably simplified. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the perspective view of the barrel winding device.
