A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft extending longitudinally along a shaft axis and having an axial shaft length to be treated. The device includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end with an applicator disposed at the distal end. The elongated rod is insertable inside the hollow engine shaft. An applicator is disposed at the distal end of the elongated rod and wetted with the surface treatment agent. The applicator is engageable with the inner surface of the hollow engine shaft for applying the surface treatment agent to the inner surface of the hollow engine shaft. A pair of markers are disposed on the elongated rod and axially spaced apart from one another at a first axial distance corresponding to the axial shaft length.

Portable hybrid system for application of any material of drywall compound material, paint material, and texture material by the hybrid system via any of a plurality of material expulsion outlet ports, comprising: a pressurizable hollow tank for carrying material, at least one air compressor for pressurizing the material from the tank, an optionally attachable paint roller subsystem, an optionally attachable paint sprayer subsystem, an optionally attachable drywall compound applicator subsystem, an optionally attachable texture applicator subsystem, and an optionally attachable edge-cutting porous paint pad subsystem, enabling a plurality of workers to apply a given material from a single tank of the material.

A tool for applying a corrosion-protection substance to a rail for securing seats in an aircraft. The tool includes a component of elongate overall shape, with a base configured to slide along the rail, and a rollers support connected to the base. The tool also has an axle incorporated in the rollers support, which extends transversally with respect to the longitudinal direction of the component on each side of the rollers support, and rollers for applying the substance mounted on the transverse axle, one on each side of the component. The tool allows the substance to be applied effectively to the flange parts of the rail that is to be protected.

A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.

The articles of manufacture a roller with an offset handle that is part of paint brush and roller system. The roller has an offset handle in which the painter grips above the plane of the roller. The handle is removable from the roller and can be used with different sizes of brush heads. The handle is designed such that the ordination of the roller's painting surface can be changed.

A multipurpose frame system providing a Y-shaped frame with angular bend attached to a U-shaped frame capable of receiving and securing a functional system, such as, for example in one embodiment, a cylindrical roller for receiving and securing a paint roller pad, and functional system separately capable of being fully disconnected.

A mechanical paint applicator assembly for applying paint to a plurality of surfaces of a vertical support of a deck includes a handle assembly. A head is removably couplable to the handle assembly. A plurality of paint rollers is coupled to the head. Each paint roller of the plurality of paint rollers is aligned on an adjustable rotational axis and is independently rotatable relative to each other. An actuator is coupled to the handle assembly and is mechanically couplable with the head. The actuator is actuated to position the paint rollers from a first position wherein the paint rollers are in alignment with each other to a second position wherein the paint rollers are angled with respect to each other.

A threaded adapter device couples a liquid compound applicator, such as a paint applicator, to a liquid compound container in a liquid-tight manner, where the liquid applicator and the liquid container cannot be directly joined because they have incompatible screw-on thread configurations, but the threaded adapter device provides threads compatible with the threads of both the liquid applicator and the liquid container, as well as providing a fluid channel from the liquid container to the liquid applicator.

The invention is relative to a roller bracket for cooperation with a cylindrical paint roller, comprising a handle and a bracket rod, and is also relative to a roller end piece. The roller end piece is wheel-shaped and has a substantially cylindrical envelope surface and a bearing for mounting on the bracket rod, wherein two roller end pieces are mounted on the bracket rod. An outer roller end piece is arranged at the end of the bracket rod and an inner roller end piece, which comprises a carried wheel with a push-off element, is arranged at distance form the outer roller end piece for removably carrying a respective end of paint roller on its respective substantially cylindrical envelope surface.

A paint roller adapter enabling a large diameter paint roller cover to be used on a paint roller frame having a cage configured to receive smaller paint roller covers. The adapter is generally cylindrical in shape and comprises a cylindrical internal surface having a diameter sized to fit onto the cage of the roller frame and a substantially cylindrical external surface having a diameter sized to fit within the large paint roller cover. At least one gripping member projects outward, beyond the external surface of the adapter such that, in use, the gripping member(s) press against an internal surface of the large paint roller cover. The gripping members of the adapter serve to prevent the roller cover slipping about the external surface of the adapter. A pair of such adapters thereby enables a conventional paint roller frame to be used with large diameter roller covers.
