1. A rotary clamp for coupling a mixing bowl to a bowl-support arm of a mixer housing, the mixing bowl having a projection extending radially therefrom, the arm having a top surface for supporting the projection and a cylindrical bore extending vertically through the arm for receiving the rotary clamp, the rotary clamp mechanism, for clamping the projection to the top surface of the arm, comprising:

  • a cylindrical clamp shaft adapted to be mounted for rotation in said bore and having a circumferential side surface;

    a head positioned on a longitudinal upper end of said clamp shaft and adapted to extend above said top surface of said arm; and

    a jaw projection extending radially from said head, said jaw having a lower clamping surface adapted to engage a top surface of said projection extending from the mixing bowl, upon rotation of said clamp shaft;

    said clamp shaft having a lower end surface and a circumferential surface, said clamp shaft including a channel providing fluid communication between said circumferential surface and said lower end surface;

    whereby said channel facilitates drainage of fluids entrained between said circumferential surface of said clamp shaft and an inner circumferential surface of said bore.
