ABSTRACT:
A paint roller is provided with a removable sleeve receiving a cover having a pile on a stretchable flexible backing. A reversible, speed controllable pump on a hand cart provides paint to the roller from a supply under control of a switch at the roller handle. The roller handle contains a radio transmitter for transmission of pump control signals to a receiver in a pump housing mounted to the hand cart. A peristaltic pump is used for the pumping, and is reversible to facilitate draining of the system back to the paint source. Opening of a door on the pump housing releases pump roller pressure from pump tubing, provides access to pump rollers and pump tubing, and thereby facilitates installation and removal of the pump tubing. Conventional water hose fittings are provided to facilitate cleaning by connection to a hose bib of a domestic water system, if desired. The entire unit is conveniently transportable on a three-wheel cart and provided with a lamp for illuminating the work, and electric power supply for the pump. A spear type intake tube is available for puncturing a paint can and removing paint directly through a punctured lid thereof, without opening the can. The cart includes a well to receive a conventional five gallon paint can, and a well to receive the roller, which well may also be used to facilitate cleaning. There is a swivel coupling on the paint supply line to the roller feed line.
