ABSTRACT:
A drain cleaning machine is disclosed which is of the character comprising a frame supporting a rotatable drum which is driven by a motor through an endless belt. The drum contains a flexible drain cleaning snake which is rotatable with the drum and axially displaceable into and out of the drum, and the frame supports a snake feeding device through which the snake extends and by which the snake is displaced into and out of the drum. The frame is wheeled to facilitate transportation of the machine from one location to another. The drum, drum shaft and bearing are constructed as a unit removably mounted on the frame. The drive motor is pivotally mounted on the frame and spring biased to tension the drive belt and to facilitate separation of the drive belt from the drum to facilitate removal of the drum unit from the frame. Stabilizer members are associated with the wheels on the frame and are pivotal between storage and use positions in which the wheels respectively engage an underlying surface and are elevated above the surface to stabilize the machine against rolling and tipping displacement during use. The snake feeding device includes three rollers which engage the snake to feed the latter inwardly and outwardly of the drum in response to rotation of the drum, and two of the rollers are radially adjustable relative to the snake through corresponding cam arrangements so that the feeding device can accommodate snakes having different diameters.
