Abstract
A coupling assembly for a portable drain cleaning machine includes a polygonal adapter mounted to a motor output shaft through a threaded interface. A polygon adapter threads over the motor output shaft in a locked male/female relationship to transmit rotation therebetween. A polygonal outer segment of the polygonal adapter telescopes into a polygonal inner segment of a sleeve mounted to the drum. The sleeve slides into a fixed cylindrical member and over the polygonal adapter to removably mount the drum. Rotation of the motor output shaft rotates the polygonal adapter which rotates the sleeve and the drum.
