A painting tool, with an internal paint reservoir that feeds paint to a roller in a relatively continuous fashion, is manipulated through an adjustable handle. The roller housing includes a pair of brackets defining a convex surface. The handle telescopically passes through the convex surface and is encircled by a ring which threads about the handle. The ring is cammed to move towards and away from the spherical surface on the roller housing, when the ring is rotated. Since the ring includes a concave surface, the translation of the ring with respect to the convex surface on the roller enables locking engagement to be attained between the handle and the roller housing. In this way the handle may be selectively fixed with respect to the roller in one of a plurality of relative angular orientations to facilitate painting. The roller housing may include a pair of rollers in fluid communication with one another and with the paint reservoir, such that paint, fed from the reservoir to a first roller, is transferred to the rotating second roller and then to the surface to be painted. The first roller includes a pair of end portions sized to sealingly abut with the roller housing and an intermediate portion of somewhat smaller diameter for transferring paint to the second roller. For this purpose, the intermediate portion may include a plurality of outwardly directed ribs or raised portions which carry the paint received from the reservoir onto the second roller. |
