Abstract: A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

Abstract: A resilient inspection brush used in electrically inspecting pipelines for abnormalities is described which employs highly conductive metals, such as nickel. Since bristles [330] made from these metals cannot be secured firmly by soldering or epoxy, they are folded over a retaining member [350], or wrapped around the retaining member [350]. The retaining member [350] is secured inside of a base housing [320]. The top [321] portion of the base housing [320] may be crimped or swedged to reduce the size of the opening, thereby physically holding the bristles [330]. This also insures that the retaining member [350] does not pass through the opening, securing the retaining member [350] inside of the base housing [320]. In another embodiment, an inner sleeve [810] is used to further secure the bristles [330] and simplify assembly.

Abstract: The present invention is directed to a brush head, particularly a toothbrush head, and to a method of manufacturing such a brush head. The brush head includes a bristle carrier and bristles fixedly secured thereto, said bristle carrier having a slot-type recess in which a multiplicity of bristles is received forming an elongated tuft with a closed, smooth outer contour corresponding essentially to the contour of the slot-type recess. According to the invention the brush head is characterized in that the slot-type recess is divided by means of at least one transverse wall into several segments, a separate tuft is inserted and secured in each of the segments, and the at least one transverse wall is constructed so that the separate tufts converge, forming in combination the elongated tuft with a closed, smooth outer contour.

Abstract: A cleaning implement comprises an elongate hollow tube. Bristle wires are bundled together and inserted fully into the tube, leaving a portion of the bristle wire projecting beyond a first end of the tube. The projecting portion of the bristle wire is trimmed to form a wire bristle brush. The first end of the tube is crimped to secure the bristles in place. When the bristles wear out, the end of the brush is uncrimped and a new length of bristle wire is pulled out of the tube. The tube is recrimped and the new bristle wire sheared off to form new bristles. The second, opposite end of the tube can be cut at an angle to form a scraper tool. Alternatively, screw threads can be formed at the second end of the tube to removably receive other types of cleaning or scraping apparatus.

Abstract: A toothbrush with a bristle head that has densely packed hexagonal tuft holes and hexagonal cross section bristles exhibits increased bristle retention. The increased bristle retention is achieved by increasing the anchored length of the tuft staple without increasing the overall length of the staple. Where the hexagonal tuft holes are of the same area as conventional round tuft holes, and the anchoring staples are of the conventional length, the "anchored" length of the staple is increased by 25%. Bristle retention is further increased by the increased friction of the flat surfaces of hexagonal bristles against each other and against the flat surfaces of hexagonal tuft holes.

Abstract: A novel toothbrush staple for a holding a U shaped tuft of bristles in a tuft hole of a toothbrush head. The staple is generally flat and its lower edge is rounded to inhibit rupturing the bristles at the bight portion of a U shaped tuft of bristles mounted by the staple in the hole. The sides of the staple are provided with one or more horizontal grooves each having a sharp edge. The arrangement of tufts and staple is such that the rounded bottom of the staple contacts the bight portion of the tuft of bristles, thus precluding rupture due to sharp edges at the staple bottom bearing against the bight portion of the tufts, especially during initial installation of the tuft in the hole. Each leg of the U shaped tuft is in contact with a respective staple surface. With the passage of time, plastic creep or flow results in the plastic on the inside wall of the hole flowing towards the staple sides and interlocking with the sharp edges of the grooves.

Abstract: The present invention relates to an improved bristled article and more particularly to an improved toothbrush which has a tuft cavity with a cross-sectional area that decreases such that the tuft cavity is broadest at the open top end and becomes narrower toward the closed bottom end of the tuft cavity. This decrease of the breadth of the tuft cavity results in a greater packing factor in the closed bottom end portion of the cavity than in the open top end and provides higher bristle retention force.

Abstract: A brush for the application of nail varnish, or a similar product, includes a tuft obtained from a bundle of bristles which are substantially parallel and folded in two halfway along their length. The bristles are fixed at the folded part in a housing opening at the end of the rod. The bristles have cross-sections bounded by a circle of constant diameter and are chosen from at least two groups. The bristles of one group are arranged so as to exhibit a different mechanical behavior in flexure to that of the bristles of the other group so that these groups give a brush tuft which is open to the air and spread out, with relatively large spaces between bristles to promote good capillary action for varnishes whose viscosity may vary over a wide range.

Abstract: A method for making a brush element for a brush roller wherein bristle bunches formed by folding bristles over bent portions of U-shaped staples have their folded portions and associated staples inserted through tight fitting apertures in a base portion of a frame so that legs of the staples are bent by collision with a facing side of an attachment section of the frame. A hardenable adhesive is then poured into the frame between the base portion and the facing side around the staples and folded portions of the bristle bunches. The adhesive is hardened, bonding the staples in the adhesive and affixing the bristles to the base portion. The adhesive may be a polyurethane-base resin having viscosity allowing absorption of the adhesive between the bristles near their folded portions, the tight fit of the bristles in the apertures holding them in place during pouring and hardening of the adhesive.

The tuft of bristles are reversely folded about a plastic filament, and the filament reversely folded whereby the free ends of the plastic filament and the associated tuft of bristles form a bundle which, when inserted into the hollow end portion of the handle is positively retained therein by the inherent resiliency of the bundle. To more securely retain the tuft of bristles to the handle, the handle may be made of plastic whereby the plastic filament can be sonically welded or fused to the plastic brush handle.
