Abstract
A socket latch drum release assembly includes a shaft release coupling which telescopically engages a rotary drum shaft to selectively lock and unlock a rotary drum of a drain cleaning machine without the necessity of tools. The shaft release coupling includes a polygonal shaped distal end which corresponds with a polygonal opening in the removable drum shaft. At least one of the plurality of faces which form the polygonal shaped distal end includes a retractable engagement member which corresponds to a recess located in each face of the polygonal opening. The drum shaft is directed into the sleeve from one side and the shaft release coupling is engaged with the shaft on the opposite side of the sleeve. Engagement between a radially extending flange of the shaft release coupling and the end of the shaft rotatably locks the rotary drum shaft into the sleeve.
