Feed control lock for hand operated drain cleaner

A manual or hand operated drain cleaner comprising:

• a manually operated rotatable drum and an elongated flexible cable at least partially held in the drum, a portion of the elongated flexible cable extending from the drum having a cable axis, rotation of the drum rotating the cable portion about the cable axis;
• a handle adapted to rotatably support the drum;
• a feed control device pivotally connected to the handle, the feed control device moveable between a non-actuating position and an actuating position;
• a driving mechanism operably associated with one of the handle and the feed control device for selectively engaging the cable, wherein in the actuating position the feed control device is pivoted relative to the handle such that the driving mechanism engages the cable thereby inducing for axial movement of the cable via rotation of the drum;
• and
• a locking mechanism operably associated with the feed control device, the locking mechanism being moveable between a lock position where the feed control device is locked in the actuating position and an unlocked position where the feed control device is freely moveable between the non-actuating position and actuating position, wherein the locking mechanism includes a locking member having a ramp portion adapted to engage one of the handle and the feed control device and maintain the feed control device in the actuating position.
