  • Patent number: 4183113
    Abstract: An improved rotary scraper having a central rotatable hub and a plurality of scraper members pivotally attached to said hub and extending outwardly therefrom for sliding engagement with and at an angle to a work surface is provided. The scraper members each comprise a coil spring disposed about a rod formed in the hub and a pair of generally parallel equal length spring fingers extending from the ends of said coil. During rotation, the scraper members are restrained in a position at an angle to the work surface by means of one finger of each pair bearing against the spring coil on an adjacent rod disposed in the hub. The finger which is restrained by the adjacent rod is stiffer than the other finger of the pair, which is restrained only by the coil, so that the degree of scraping action can be controlled by the pressure exerted upon the hub to bring the less stiff finger or both fingers into contact with the work surface.

  • Patent number: 4168863
    Abstract: A method of making a scouring pad from a length of nylon fabric netting characterized by forming the netting into a tube-like configuration by rolling the netting around two spaced cylinders having unequal diameters, but axially spaced from each other, twisting the tube of netting to gather the netting in the location between the two cylinders, folding the netting onto itself by extending one cylinder over the other cylinder to form one end of the pad, removing both cylinders from the netting tube, wrinkling and tucking the netting toward the other end of the pad to form an inside core, gathering the outside netting around the inside core, and twisting and tieing the outside netting to form the other end of the pad. The scouring pad may be made from a single length of fabric netting or alternatively made from two separate differing colored lengths, thereby resulting in a two-toned pad wherein the color of the inner core netting and outside netting are dissimilar.

  • Patent number: 4167796
    Abstract: A brush apparatus for the cleaning and polishing of a surface having the advantages of an elongated handle with two or more spaced-apart, raised elastomeric rings to stop the flow of cleaning liquid onto the handle and onto the hand of the user.The head of the brush is tapered and holds an abrasive-resistant foam or bristle rubbing pad to ease the removal of spots that otherwise would be difficult to clean. The ends of the bristles of the brush are feathered to allow for greater pickup of dirt when used dry and for the gentle cleaning of large areas when wet.

  • Patent number: 4164800
    Abstract: A combination mop and wringer comprising a handle and a replaceable strand type mop positioned at one end of the handle. A slide arm reciprocates relative to the handle from an initial position to a wringing position to push a pivotal, split ring member over the strand mop to wring out excess water. The slide arm reciprocates through a guide block having a configured opening to prevent twisting of the slide arm during movement. Reciprocation of the slide arm returns the split ring member to its initial position ahead of the strand mop. The split ring includes a pivotal connection to the slide arm and a flapper type closure to automatically complete the ring configuration prior to each mop wringing cycle. The slide arm may be provided with a locking detent suitable to releasably engage the guide block to retain the slide arm in its initial position.

  • Patent number: 4164801
    Abstract: An ice scraper comprising a one-piece body defining a handle section, a downwardly curved intermediate section, and a blade region comprising a plurality of downwardly curved, independently flexible, resilient scraping fingers. In use, the scraping fingers bow or flex when scraping force is applied to ice to be removed, induce the formation of fractures in the ice, and thereafter resiliently return to their unflexed position, imparting force to fractured ice tending to throw it away from the surface to be scraped.The separable, independently flexible fingers enable the ice scraper to effectively conform to curved surfaces and avoid the possible incomplete cleaning action of said blade structures.
