  • Patent number: 5249330
    Abstract: A paint roller applicator to create in a user's mind that a paint roller applicator is a tool that can replace a paint brush for applying paint to large or small surfaces, with the invention including a socket housing for holding a paint roller frame, with the socket housing mountable on the base of a conventional paint brush handle, so that a user has a conventional paint brush handle as a hand grip on a paint roller applicator to acquaint the user that a paint roller applicator can be used on large or small surfaces. The user can mount the frame of the paint roller applicator directly in the base of the paint brush handle or in a socket housing that is frictionally held in the normal ferrule band on a flat blade paint brush handle with the socket housing including a member for interlocking connecting the frame of a paint roller applicator thereto and lips for holding my paint roller applicator on the edge of paint tray when the paint roller applicator is not in use.

  • Patent number: 4566816
    Abstract: A pressure fed paint roller includes a paint roller shield and handle, a paint roller mounted for rotation within the shield, and a two-piece floating manifold positioned between the top of the shield and the roller. The manifold has a concave paint spreading surface with a row of spaced discharge openings from which paint is discharged under pressure onto the roller surface. An adjustable resilient loop connected between the manifold and the shield urges the manifold toward the roller so that this paint spreading surface engages the paint roller and forces the paint into the outer covering of the roller without impeding rotation of the paint roller.

  • Patent number: 4191792
    Abstract: A paint roller for producing texture paint surfaces having a cylindrical core with a paint applying and texturing cover bonded to the outer surface of the cylindrical core. The paint applying and texturing cover is an open web of interengaged continuous crinkled coarse filaments of resilient material. The open loops of the open web carry the texture paint material, apply it to the surface being painted, and texture it in essentially a single motion. During application, the loop elements are actually immersed in the texture paint material and lift it into peaks, thereby producing deeper textures than has generally been possible in the past.

  • Patent number: 4155140
    Abstract: A paint applicator has a handle and a pad supporting base. A paint applying pad is attached to a first face of the base. First and second flanges, a groove, and a ramp are provided on a second face of the base for receiving and holding the handle. The handle includes a plate with side walls and a lip extending below a front edge of the plate, and a gripping portion. To assemble the paint applicator, the plate is inserted into and slid rearwardly in the first and second flanges. The lip is guided up the ramp and into the groove, where the plate is held in a locking position by the first and second flanges engaging the side walls and the groove, where the plate is held in a locking position by the first and second flanges engaging the side walls and the groove engaging the lip.
