Abstract
A drive shaft is for a rotary plate of a labelling machine for bottles or the like and includes a rotatable turntable of the labelling machine having an upper portion. A circular cam block is mounted below the turntable and has a curved slot therein. The rotary plate is mounted for rotation on the upper portion of the turntable. A drive shaft is mounted for rotation in the turntable and has an upper end and a lower end. The rotary plate is coupled to the upper end of the drive shaft. The lower end of the drive shaft includes a crank arm which is disposed in the curved slot for cammed rotation of the drive shaft during rotation of the turntable. The curved slot includes an opening in the cam block and the drive shaft including the crank arm is alignable with the opening for downward removal from and upward installation in the turntable through the opening. There is also included a feature of the rotary plate being mounted on a base plate which is selectively positionable on the turntable for either direct coupling or geared coupling between the rotary plate and the upper end of the drive shaft.
