ABSTRACT:
A reciprocating sander particularly adapted for sanding remote surfaces such as ceilings and walls is provided by concentrating a substantial part of the weight of the sander in a motor assembly. A lightweight extension tube extends from the motor assembly to a universal joint which in turn is coupled to a sanding attachment. The sanding attachment includes clips which secures a piece of sandpaper in an mechanism for converting angular rotation of the universal joint into relative reciprocating motion of a sanding plate and sandpaper with respect to the sanding attachment. By bringing relative force between the sanding attachment and the motor assembly, a resiliently retained driving rod within the extension tube, which is coupled to the universal joint and sanding attachment, is forced downwardly in the extension tube toward the motor assembly. This ultimately causes two clutch parts to engage thereby permitting the transmission of the motive force to the sanding attachment. The reciprocating sanding plate carrying the sandpaper has a distance of reciprocation just equal to the overhang of the basal plate of the sanding attachment so that no dead zone is established around the periphery of the sanding attachment which is not effectively reached by reciprocating sandpaper. The universal joint coupling the sanding attachment to the extension tube is provided with contoured mated bearing surfaces so that the universal joint smoothly operates even when the joint is configured into extreme angular configurations which brings opposing parts of the joint in contact with each other.
