Abstract
Various feed control devices for plumbing tools such as drain cleaning machines are disclosed. The feed control devices include a collection of angled rollers that contact a cable or snake of the drain cleaning machine. Another collection of a single or dual angled roller(s) are mounted or otherwise engaged with a handle, and can be selectively positioned and contacted with the cable. By changing the position of the handle, rotation of the cable is translated to axial movement thereby advancing or retracting the cable. Also described are drain cleaning devices utilizing the feed control devices.
