Drain cleaning apparatus

A drain cleaning apparatus comprising:

• a drum containing a supply of flexible line suitable for cleaning a drain;
• a frame;
• means cooperating between the frame and the drum for removably mounting the drum in an operative position on the frame for rotation relative to the frame,
• whereby a length of the cable projecting from the drum can be engaged by a control means to selectively advance the cable from the drum and cause the cable to move back into the drum as the drum and cable length are rotated in use;
• means cooperating between the cart and at least one of the frame and drum for releasably operatively connecting the cart and the one of the frame and drum to allow the cart to be used to transport the drum and frame as a unit;
• and
• means cooperating between the cart and the drum for releasably connecting the drum to the cart to allow the drum to be transported by the cart without the frame.

A drain cleaning apparatus comprising:

• a drum containing a supply of flexible line suitable for cleaning a drain and defining an axis;
• a frame;
• bearing means cooperating between the frame and the drum and axially engageable with the drum for removably mounting the drum for rotation relative to the frame when the drum is in an operative position,
• whereby a length of the cable projecting from the drum can be engaged by a control means to selectively advance the cable from the drum and cause the cable to move back into the drum as the drum and cable length are rotated in use;
• a cart;
• interchange means operatively associated with the frame for facilitating installation and replacement of a drum in operative position;
• and
• a coupling member on the cart selectively movable between a first position in which the coupling member is engageable with the frame and a second position in which the coupling member is engageable with a drum for selectively releasably connecting the cart and the frame so as to a) allow the cart to be used to transport the drum and frame as a unit in an operative position and b) allow the cart to be detached from the frame to allow the coupling member to be used to transport at least one of a different frame and a drum.

In a drain cleaning apparatus having a drum containing a supply of flexible line suitable for cleaning a drain and a frame for rotatably supporting the drum and including means for advancing line therefrom, the drum being removably mounted on the frame such that the drum can be interchanged with a replacement drum, a cart for selectively transporting the drum and frame as a unit and transporting a drum without the frame, the cart comprising:

• a base having means for enabling the cart to be easily moved along a subjacent surface;
• an upright handle extending from the base;
• and
• a coupling member movable between a first position for releasably operatively connecting the cart and at least one of the frame and drum to allow the cart to be used to transport the drum and frame as a unit, and a second position for releasably operatively connecting the cart to the drum to allow the drum to be transported by the cart without the frame.
