ABSTRACT:
A well cleaning attachment useful as a part of a collection of tools sent down a well bore on a tubing string includes a tubular mandrel provided with a plurality of longitudinal slots in which corresponding knife carriers are inserted. Each carrier is bedded on a leaf spring for radial motion within the slot and each is provided with a spring biased blade extending pivotally to the exterior. Two collars then fix the carriers within the slots, the same collars also engaging the periphery of the mandrel.
