Patent number: 5606762Abstract: A roller brush and method of making same for sweeping machines for cleaning streets and roads. The brush includes cassettes arranged in brackets around the periphery of a roller and extending in the longitudinal direction of the roller. The cassettes receive spring members, such as radially projecting bristles, the ends of which are brought in contact with ground when the brush is used for cleaning. The cassettes are received in grooves in the brackets. The spring members are bent double around a locking wire which acts to hold the members in the cassettes and which passes through holes in connecting cross walls extending from facing long sides of the cassettes. The connecting cross walls are provided at spaced locations along the cassette thereby defining cells on the cassette. The spaced connecting cross walls act to increase the rigidity of the cassette.Type: GrantFiled: September 15, 1994Date of Patent: March 4, 1997Assignee: Filippa I V aster.ang.s HBInventors: Walter Droeser, Hans Ekholm

Patent number: 5378051Abstract: 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.Type: GrantFiled: November 30, 1993Date of Patent: January 3, 1995Assignee: Oy C.E. Lindren AbInventors: Mauno Kirkkala, Reijo Kuivikko

Patent number: 5251355Abstract: A bristle strip for rotary brushes comprising a supporting channel in which the closed ends of the U-shaped bristles are clamped. The channel is provided with laterally-extending guide members mounted directly thereon that project laterally outwardly beyond its side flanges to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein. Due to the simple nature of the strip it can be produced at a low cost without special tooling.Type: GrantFiled: October 9, 1992Date of Patent: October 12, 1993Inventor: Arthur E. Drumm
-
Patent number: 5159736Abstract: A brush construction which includes a brush handle having a hollowed end portion for receiving a tuft of bristles. 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.Type: GrantFiled: June 17, 1991Date of Patent: November 3, 1992Assignee: Andor Brush CompanyInventor: Robert L. Newell

Patent number: 5155875Abstract: A brush roller (1) includes a cylinder section (2) and brush elements (4) attached to it. In each element (4) the bristles (6) are attached in essentially a radial direction. The cylinder (2) of the brush roller (1) includes longitudinal rails (3), and each element (4) includes an indentation (7), which attaches the element (4) to the rail (3), and one or more elements (4) are sequentially arranged to be pushed onto each rail (3).Type: GrantFiled: September 17, 1990Date of Patent: October 20, 1992Assignee: Oy C.

Patent number: 4518452Abstract: A grinding- or polishing implement can be produced by providing a rectangular sheet (1) at both sides with segments (2) formed by slits from the outside towards the center. Hereafter the sheet is folded around the center across a glue string (5), and then the two folding edges are folded together and glued together for the formation of a closed ring. This ring can thereafter be placed on a spindle (6) preferably between retaining discs (8).In this way raw material can be saved in the production of rings, just as the rings can be used more economically in an implement as the grinding qualities are improved through the big number of segments, their completely uniform size and placing along the periphery of the implement and their ability to adjust and shape themselves according to the prepared members.Type: GrantFiled: June 30, 1982Date of Patent: May 21, 1985Inventor: Keld O. Hundebol

Patent number: 4485514Abstract: A brush ring for a roller brush in a cleansing machine includes a ring with U-shaped cross section and having openings with upstanding walls into which the bent-over ends of the hairpin-like bristle bundles are thrust. The bent-over bristles are free inwards of the inside of the ring, and a locking wire is taken through these ends to form a locking wire ring on the inside of the annular bar for reliably retaining the bristle bundles in the openings when the ring is rotated during operation.Type: GrantFiled: October 25, 1983Date of Patent: December 4, 1984Inventor: Walter Droeser

Patent number: 4356587Abstract: A method of manufacturing brush components is disclosed wherein an array of bristles which may either be loosely arranged in which case they should be substantially aligned or may be in the form of a knitted or woven tape is overlain by a membrane e.g. a polythene or polypropylene sheet, the bristles and membrane then being bent through 180.degree. about the center line of the array into a generally U-shaped configuration and subsequently held in that position by clamping means e.g. a metal channel or an extruded plastics beading. Preferably a strengthening wire is located over the top of the membrane and within the U at the base thereof.Type: GrantFiled: August 6, 1980Date of Patent: November 2, 1982Assignee: Schlegel (UK) LimitedInventor: David Holding

Patent number: 4115895Abstract: A method and apparatus for constructing a mop head comprising a ram adapted to be urged downwardly having a ram head thereon to insert a rigid mop fiber securing wire into a preformed mop head. As the ram moves downwardly, the head is aligned with and engages a resiliently mounted mop head support apparatus in which a mop head is inserted. Mop fibers are placed over the mop head and metal fingers are positioned over the ends of the mop head. The ram head engages guide members to align the securing wire with the mop head and the ram is urged downwardly, causing the ends of the wire to engage the metal fingers such that the wire is moved past the metal fingers and under shoulders formed in the ends of the mop head and securely positioned thereon and retain the mop fibers therein. The fibers frictionally engage the sides of the mop head and are retained therein by the wire.Type: GrantFiled: February 4, 1977Date of Patent: September 26, 1978Assignee: Dallas County Association for the BlindInventor: Audrey H. Ballew
