Patent number: 5997205Abstract: In order to supply a coating to a roller, a coating supplying groove is provided along only one side of a core which is connected to an end of a support so as to act as a shaft of a roller. A coating reservoir between the roller and the core is located to one side of the core. To permit engagement and disengagement between the support and the core, an elastic member is mounted within a coating flowing hole of the core, while an inserting groove and a stopping groove are provided in the inner peripheral surface of the coating flowing hole of the core. To automatically stop and start the supply of coating to the coating roller, and to adjust the flow rate, the number of revolutions of the roller are detected and used to actuate the coating feed mechanism to supply coating at a flow rate corresponding to the number of revolutions and or direction of rotation of the roller.Type: GrantFiled: March 25, 1998Date of Patent: December 7, 1999Inventor: Takanori Koide

Patent number: 4540301Abstract: A peristaltic-type pump having an intake which may be conveniently connected to a liquid coating source includes an impeller having a pair of rollers. Rotation of the impeller causes the rollers to progressively compress a length of tubing in the pump. This compression creates suction to draw the coating material into the pump and pressure to drive a flow of coating to a handle attached to an applicator. The handle includes flow control devices which may be selectively operated to supply coating to the applicator only as required. During periods of non-flow the coating pressure is sensed to deactivate the pump when the pressure exceeds a preselected limit. Deactivation of the pump saves energy and prolongs a life of the pump.Type: GrantFiled: December 16, 1983Date of Patent: September 10, 1985Inventors: Dennis E. Swanson, Robert D. Lerum

Patent number: 4537522Abstract: A fluid applicator includes a fluid applicator roller engaged with a fluid dispersing roller. The fluid dispersing roller includes a pair of helical fluid dispersing troughs which receive fluid from an electric motor driven pump which is operated by a low voltage electric switch control located on a handle of the fluid applicator.Type: GrantFiled: July 1, 1983Date of Patent: August 27, 1985Assignee: EPR CorporationInventors: Joseph C. Charney, Phillip M. Goodman, Robert H. Morgan

Patent number: 4478671Abstract: A liquid-adhesive applicator has a hollow cylindrical reservoir formed of a somewhat flexible plastic material and closed at each end by rigid plastic end caps. A stiff but bendable rod axially rotatably supports the reservoir, and is bent to form the shank of a handle for the applicator. The reservoir has a plurality of pairs of slits parallel to the axis of the reservoir and angled inwardly midway between radial and tangential orientation. Molded-on protuberances between the pairs of slits cause the slits to open when the applicator is pressed against a surface, such as the edge of a two-by-four stud, to apply adhesive thereto. In a second species the cylindrical reservoir and the end caps are cemented, or are thermoplastically welded, together; and are further made into a sealed toroidal reservoir by an axial tube that prevents leakage if the reservoir unit is discarded for throw-away replacement by a new head unit.Type: GrantFiled: March 16, 1983Date of Patent: October 23, 1984Inventor: James D. Freeman

Patent number: 4302122Abstract: A rotary brush for applying paint to surfaces comprises a housing, a rotatable hollow cylindrical body which bears on the cylindrical surface a plurality of brush units, motor means, passage means for supplying paint from a supply channel to the bristles of the brush units, and a number of stationary guide rings mounted rigidly in the housing and guidingly surrounding the rotatable cylindrical body. The guide rings are disposed in zones transverse to the axis of the cylindrical body and distributed over the length of the same. Each ring bears a slidable bearing means adapted for bearing, for instance with a loose wheel at its free end, against the surface to be painted, thus relieving pressure of the bristles on the surface to be painted.Type: GrantFiled: December 10, 1979Date of Patent: November 24, 1981Inventor: Liborio A. Moya

Patent number: 4285736Abstract: A method and apparatus for washing the surface of an object in which a rotating brush is provided. The bristles of the brush are supplied with a washing liquid through a hollow shaft for a limited angular rotation so that the washing liquid effectively is transmitted to the ends of the bristles substantially only during the time they make contact with the surface.Type: GrantFiled: July 3, 1979Date of Patent: August 25, 1981Inventor: Laszlo Arato

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. Groth, John D. Vogel, Guilbert M. Hunt

Patent number: 4217062Abstract: An apparatus into which a can of paint is placable, the apparatus including a motor driven pump that draws the paint from the can and through a hose into the interior of a paint roller from where it filters through the roller and upon its outer surface so to be applied to any surface being painted, the roller including a perforated hollow cylinder covered by lamb wool on its outer side so the paint can soak therethrough; and the apparatus in a modified design being developed to deliver paint in a controlled manner from two paint cans to a common paint roller.Type: GrantFiled: February 27, 1978Date of Patent: August 12, 1980Inventors: Peter Trp, Mile Lipovac, Rodolfo Ribich, deceased, by Virginia Ribich, legal representative
