ABSTRACT:
A paint roller construction comprises a roller which is supported on a support which has a handle. The support carries an electric drive motor for a pump which supplies a paint through a connecting conduit in the support directly into the roller. The interior of the roller is maintained at a predetermined pressure in order that the paint may be delivered outwardly through the pores of the roller applicator surface at a controlled rate for application on a surface. The device also advantageously includes a drive motor which may be operated at a selected speed in order to rotate the roller at an amount which is comparable to the pressure of the paint supply so as to apply the paint at a predetermined application rate and thickness. In one embodiment the drive motor is carried on an end bracket of the paint roller support and directly drives the roller either electrically or by the fluid action of the paint which is delivered to the roller and preferably the drive of the roller is variable as is the supply of the paint in order to provide a complete control for the paint application. In another embodiment the paint is contained in the handle for the paint roller and it is supplied at a controlled rate to one or more sections of the roller in order to vary the application amount along the length of the roller and it is applied at a rate comparable to the rate of rotation of the roller. The roller itself may contain both the paint supply and pump as well as the motor for driving the roller during application.
