Patent number: 4231668Abstract: A coatings application apparatus pumps liquid paint through a flexible conduit within a rotary variable displacement peristaltic pump to a conventional applicator head. Through constant speed rotating lobes peristaltic action squeezes coating liquid within the conduit through the paint applicator control handle and applicator.The control handle permits changes in the paint flow rate. Upon constriction of the conduit within the control handle, flow rate is reduced, back pressure develops with resulting tube distortion. Distortion levered forces act upon a pre-set loaded pump spring. Variation in pump displacement results. The liquid flow rate within the supply conduit is inversely proportional to the back pressure so developed. If fluid flow is completely arrested by full supply tube constriction, back pressure becomes a maximum and pump displacement becomes zero. The pump continues to operate, however, at constant R.P.M., requiring no high starting torque.Type: GrantFiled: October 5, 1978Date of Patent: November 4, 1980Assignee: The Sherwin-Williams CompanyInventors: Hugh F.

Patent number: 3933415Abstract: A painting system has a container and a flexible wall with a source of pressure on the flexible wall for extending the flexible wall toward the paint and forcing paint through an opening, a valve and a conducting tube into an applicator. A membrane is fitted inside a container, and a cover is placed over the container. Ordinary water pressure from a tap is fed through the hose into the membrane area forcing the membrane toward the paint, and forcing the paint from the container. In one applicator, paint is fed into a hollow tube which is turnable to align openings in a tube wall with distributors which communicate the paint to a plurality of tubes. Paint flows through the selected tubes through an array of openings in paint distributing surfaces. A relatively narrow, pointed surface extends outward from a relatively large circular surface. An auxiliary distributing surface extends perpendicularly to the pointed surface. A sponge roller is provided with a fitted cover and is positioned over a foraminous tube.Type: GrantFiled: May 11, 1973Date of Patent: January 20, 1976Inventor: John C. Woolpert
