Abstract
The invention is an improvement in a drain-cleaning auger of the type having a round shell made from first and second subshells and a cavity within the shell for housing a drain-cleaning snake. In the improved auger, the first subshell has an outwardly-flared sidewall which increases in diameter and has its maximum diameter at the sidewall edge. The second subshell has an edge in close proximity to that of the first subshell. The subshell edges define a crack or slit-like opening between them for expulsion of water from the cavity by centrifugal force when the shell is power-rotated at high speed. The auger is thereby self-drying.
Claims10
In a drain-cleaning auger of the type having a snake and a round shell made from first and second subshells connected to one another to define a snake-containing cavity within such shell, the improvement wherein:
- the first subshell has a sidewall flared to a first edge of maximum diameter;
- the second subshell has a sidewall flared to a second edge of maximum diameter, the second edge being in intermittant contact with the first edge to define plural openings between the edges for expelling water from the cavity by centrifugal force when the shell is power-rotated at high speed;
- and,
- no portion of the snake passe through an opening, thereby permitting unobstructed water expulsion,
- whereby the auger is self-drying.
