ABSTRACT:
A cleaning device for cavities, particularly in chill moulds for steel ingots, is desired comprising a body provided with cleaning means by way of example brushes which face away from said body and are expandable away from each other in order to engage the walls of the cavity which is to be cleaned by displacement of the body to and fro along the walls of the cavity. The cleaning means are carried by outer arms in a pivotable way carried by levers having upper and lower ends with the cleaning means mounted on the lower ends, the levers being mounted in bearings on the body. Springs are arranged to pivot the external ends of the lever arms outwardly away from the body and to pivot the cleaning means inwardly toward the body so that the cleaning means in an otherwise unactuated position form an oblique angle to the direction of displacement.
