ABSTRACT:
A paddle shaft assembly for a mixing apparatus including a quickly and easily removable quill shaft provided with a unique seal structure associated with the shaft and a unique mounting and handle structure to enable disassembly of the shaft in relation to a mixer drum and paddle assembly in the drum. The removable shaft is provided with a flanged end plate having keyhole slot connections to a flange on the end of a rotatable sleeve sealed in relation to the drum for removably supporting the shaft and a loop type handle attached to the end plate to facilitate manipulation of the end plate and shaft to remove and replace the shaft. A seal assembly is associated with the shaft, rotatable sleeve, end plate and flange to seal those areas of the shaft and sleeve to preclude passage of the material being mixed into the area between the shaft and rotatable sleeve, and between the flange and end plate.
