Abstract
A synchronizing clutch made up of a quill shaft, a hub, a toothed sleeve for connecting the hub to the shaft and a clutch between the sleeve and the hub for synchronizing the speed of the hub with the speed of the sleeve prior to connecting the hub teeth to the shaft teeth. Drive pins are provided on the shaft for preventing the teeth from interfering at synchronization and an improved adjusting means and a retaining ring provide a space for the clutch discs so that the axial position of the clutch discs relative to the drive pins prior to synchronism is always precisely known.
