Abstract

A cleaning arrangement for cylindrical bores and in particular gun barrels. The cleaning arrangement, when in operation, automatically axially reciprocates in the gun barrel. The arrangement includes a carrier on which at least one drive motor is mounted. Electrical energy supply means are connected to the drive motor. A container for holding cleaning fluid is also mounted on the carrier and rotary brush means are connected to the drive motor via gear train means. Entering means are mounted on the carrier and maintain the cleaning arrangement in substantial axial alignment with the gun barrel via a plurality of radially outwardly biased drive rollers which bear against the interior surface of the gun barrel. The rotary brush means are rotated by the drive motor via the gear train means about the longitudinal axis of the gun barrel. The drive rollers, when rotated by the drive motor, also serve to axially advance the cleaning arrangement in the gun barrel.
