Abstract
A mechanism for securing multiple apparatus to a drain cleaning machine is described. The mechanism includes a bracket arranged on a frame of the drain cleaning machine. The bracket allows a drum and a feed mechanism to be removably secured to the frame. The bracket includes a base and pivotable latch. A drum bearing from the drum can be secured between the base and the latch when the latch is in a closed position. Mounting pins from the feed mechanism can be inserted into two bores in the bracket, and secured therein by plunger pins. One plunger pin is manually operated, to selectively lock the latch in the closed position, and to selectively secure one of the mounting pins in one of the bores. Another plunger pin is operated by pivoting of the latch, and functions to selectively secure the other mounting pin in the other bore.
