A pressure fed roller type fluid applicator is disclosed which comprises a frame having a handle and spaced means for supporting thereon in free rolling relation an applicator roller together with a fluid feeder member in the form of an elongate tube of small diameter mounted adjacent the exterior surface of the applicator roller and having a perforated wall so as to discharge liquid onto the exterior surface of the roller, the fluid being supplied through conduit forming means extending from a fluid supply source through the handle and connected to the feeder tube, with a conveniently positioned, manually operable, fluid control valve in the supply line.

A roller type application device for applying a paint or other flowable material to a surface which device comprises an applicator roller, a frame having a handle forming portion and spaced arm members having means for rotatably supporting said roller, means for feeding material to the roller surface which is in the form of a relatively small diameter tube mounted relative to said roller so as to extend generally parallel to the axis of rotation of the roller and substantially in contact with the exterior surface of said roller, which feeder tube is apertured so as to discharge material supplied thereto onto the roller surface substantially throughout the axial dimension of the roller, said aperture in said feeder tube being in confrontation to said applicator surface and is formed as a slot extending substantially the length thereof for uniformly passing paint or other flowable material therethrough for application throughout substantially the axial dimension of the roller surface, means connected to said material feeding tube for supplying material to said tube and a valve for controlling the feeding of said material to said tube, said spaced arm members have means for supporting said roller which includes releaseable trunnion forming members and associated end caps for said roller which end caps include an aperture and compressible roller engaging flange portion for accommodating variations in the diameter of the roller, said releaseable trunnion includes a flexible flat member and a pin mounted thereon, said flat member urging said pin into engagement in said aperture for releaseable support of said roller, means for securing said flat member to said spaced arm members at a position spaced from said pin, said tube for feeding material to the roller surface is mounted at its ends on spring pressed arm members having means for adjusting the position of said tube relative to the surface of the applicator roller, said tube mounting arm members are pivoted on said frame and have associated torsion springs for urging the tube in the direction of the roller surface, and said torsion springs having an intermediate portion coupled to said means for securing said flat member and an end portion coupled to said tube for feeding material.
