ABSTRACT:
An improved plumbers' tool of the type employing a helically wound coiled spring which is controllably inserted into waste lines to remove blockages. In operating the tool of the invention a storage drum from which the clean-out spring is payed out is rotated, usually by a small electric motor, and the spring is clamped in a chucking mechanism so as to rotate with the housing. The improvement of the present tool resides in the provision of a unique double fulcrum actuating mechanism which enables the operator, using only one hand, to smoothly and almost effortlessly cause the chucking mechanism to securely engage the coiled spring and prevent slippage thereof even during highly troublesome clean-out operations.
