Applicator devices and methods for dispensing solid and liquid materials therefrom are disclosed. The applicator devices provide for application of a wide variety of liquid and solid materials from a hand-held device in combination with a buffing element. The devices generally include a top portion that forms a housing and a bottom portion that defines a buffing element. The top portion incudes an interior side that defines an inner cavity configured to contain the liquid or solid material and an exterior side having at least a portion configured to be grasped by a user's hand. Attachment between the housing and the buffing element may be releasable so that various interchangeable buffing elements may be used in combination with the liquid or solid material contained in the housing of the device.

A paint brush cleaning system includes a housing and a paint brush cleaner attached to the housing. The housing contains solvent that helps clean a paint brush. The paint brush cleaner rotates a wire brush against the bristles of the paint brush and actuates a pump to eject solvent drawn from the housing as the paint brush is moved in translation. The wire brush is coupled to a retractable cord, which rotates the wire brush. A holder is simultaneously coupled to the retractable cord and the pump. When force is exerted on the holder, the retractable cord rotates the wire brush and the pump ejects solvent. A user can insert a paint brush handle through the holder, thus actuating the pump and rotating the wire brush by applying force to the handle. The housing attaches to a user's belt, providing easy access to the paint brush cleaning system.

A grill cleaner apparatus for cleaning a grill using rotary power from an external source such as a hand drill, having a drive shaft and cleaning wheels such as wire brush wheels, with two cleaning wheels rotating perpendicular to the drive shaft and cleaning grill bars and additionally propelling the grill cleaner forward.

The Ergonomic Handle Scraper includes an ergonomic handle device that may be adapted to perform a wide variety of tasks such as scrubbing, scraping, scooping, cutting, brushing, painting, sanding, grating, shaving, etc. The device may be produced in a wide variety of shapes and sizes and may be constructed from a wide variety of materials and manufacturing processes. The Ergonomic Handle Scraper provides a user with a compact, ergonomic handle which may be used in conjunction with other adjoining and complementary shapes, materials, surfaces, textures or tools. More specifically, the ergonomic handle is the basic component that enables other components to be combined with or extended from the handle.

A rotary wire brush, such as a wheel brush, e.g., double-stringer or dually brush, cup brush, bevel brush, or knotted end brush, composed of knotted brush wire tufts of multistrand construction each having at least a plurality of brush wire strands, preferably at least a plurality of pairs of, i.e., at least three, strands each formed of at least a plurality, preferably at least a plurality of pairs of, i.e., at least three, wires. The wires forming strands are twisted, braided, or twisted and braided, and the strands that form tufts are twisted, braided, or twisted and braided. A preferred brush employs a center disc, e.g., hub, with radially offset tuft anchor holes, which can have different sizes, from which twist knot tufts, which also can have different sizes, can outwardly extend from the disc different distances by being configured with an offset trim preferably having different trim lengths.

A segment for detachably arranging on a carrier, which can be rotatably mounted relative to an axis of rotation, for forming a disc brush or for forming a cleaning, grinding or polishing disc, includes a segment body, wherein multiple bristles protrude from the underside thereof or an abrasive grit and/or a fiber structure is arranged on the underside thereof, wherein the segment body has a segment guide extending in the radial direction in relation to the axis of rotation of the carrier on a radially internal edge and spaced apart from an external—in relation to a circumferential direction—lateral edge of the segment body, which segment guide is designed to cooperate with a corresponding carrier guide formed or arranged on the carrier for arranging the segment on the carrier.

A cleaning tool for cleaning accumulated charred food material on grill grates. The cleaning tool is of a two-prong tuning fork shape that has a handle and a cleaning head. A shaft extends between the two prongs of the cleaning head. Several cleaning discs are slidably provided between the two prongs over the shaft wherein two adjacent cleaning discs are separated by one or more spacer discs. the cleaning discs scrap the accumulated material from the grill bars.

A method of cleaning and polishing a backside surface of a semiconductor wafer is provided. The method includes placing an abrasive brush, comprising an abrasive tape wound around an outer surface of a brush member of the abrasive brush, on the backside surface of the semiconductor wafer. The method also includes rotating the brush member to polish the backside surface of the semiconductor wafer by abrasive grains formed on the abrasive tape and to clean the backside surface of the semiconductor wafer by the brush member which is not covered by the abrasive tape.

A double-stringer rotary brush assembly formed of a pair of brush wire mounting hubs having sets of alternating radially staggered radially innermost and outermost brush wire tuft mounting holes having different hole sizes with brush wire tufts extending radially outwardly therefrom having at least one of (a) different lengths, (b) an offset trim, and/or (c) differently sized knots anchoring the tufts thereto. One hub can be angularly offset relative to the other hub angularly offsetting the holes of one hub relative to the other hub from being concentric. The tufts extending from one of the radially innermost and outermost holes are stiffer than the tufts extending from the other one of the radially innermost and outermost holes imparting to the brush assembly tufts having different surface finishing and abrasive removal characteristics.
