  • Patent number: 5213121
    Abstract: A brush holder mounted on a container of cleaning fluid includes clips engaging the handles of one or more brushes to support the brushes with the bristles thereof extending vertically into the cleaning fluid. Two vertically-spaced motor-driven cranks, rotatable in synchronism with each other about vertically spaced horizontal axes, have a horizontally extending crank pin, the lower crank pin being received in a hole in the brush holder, and the upper crank pin being received in a slot in the brush holder.

  • Patent number: 4717276
    Abstract: A paint roller is provided with a removable sleeve receiving a cover having a pile on a stretchable flexible backing and retained by end caps with a bayonet-type connection for convenient installation and removal of the cover. 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.

  • Patent number: 4661045
    Abstract: A painting apparatus has a peristaltic pump having a pump cavity in a pump body and a pumping tube in the cavity. The cavity is provided with an elongate drain passage. A photoelectric sensor is arranged to receive light from a light source, both being associated with the drain passage to sense any leakage of paint from the pumping tube draining into the drain passage and to thereupon stop the pump. An alert light may be provided for signalling that paint leakage has stopped the pump. Preferably, a funnel-like transparent container is removably fitted in the cavity below the pumping tube to receive the paint leakage. The container has a spout-like downward extension engaged in the drain passage but allowing transmission of light to the photoelectric sensor.

  • Patent number: 4599009
    Abstract: Described briefly, according to a typical embodiment of the invention, a roller has a core comprising plurality of relatively hard and rigid segments fastened together in a stack and rotatably mounted to a shaft. The roller core has internal baffled passageways established by grooves in abutting faces of segments, so that, when paint is supplied to a cavity in the center of the stack, it will depart through these passageways in the roller in a controlled manner. A diaphragm seal assembly is provided to prevent leakage of pressurized paint. A replaceable sock-like cover is received on the roller stack and secured by end retainers. The roller can be easily and completely disassembled for cleaning.
