  • Patent number: 5535473
    Abstract: A drain cleaning system which utilizes a plumbing cable and nozzle assembly. A fluid-conveying hose is incorporated within a plumbing cable and a nozzle is affixed to the distal end of the cable and in communication with the hose. The nozzle includes a body having a rounded radius tip and a rotatably mounted ring having a plurality of radial jet passages formed therein. The ring and the body cooperatively define an annular passage therebetween. Pressurized water passes through the nozzle body and into the annular passage to produce a water bearing. The water is then discharged through the jet passages in the ring, causing the ring to rotate about the water bearing to produce a rotating spray of pressurized water. The rounded tip and ring are oriented co-axially with the tip being wider than the ring to prevent the jet passages from clogging when the nozzle is used to penetrate a clog in a pipe.

  • Patent number: 5535472
    Abstract: A denture cleaner powered by a stream of falling water. A first rotary brush is geared to the gear. A second rotary brush is arranged at an angle to the first brush, with the bristles of the two brushes intersecting. The water falls onto a turbine or water wheel, which turns the first brush through a reducing gear. The first brush frictionally or interfittingly drives the second brush. Dentures are placed between the two brushes, and are held in place by the configuration of the cleaning chamber. Two pairs of brushes arranged in this manner are provided for cleaning two sets of dentures simultaneously. The water wheel is arranged selectively to divert a portion of the water stream into the cleaning chamber. A pocket having a perforated wall dispenses a cleaning agent into the cleaning chamber. The denture cleaner is thus independent of power from a manual, electric, or fluid pressure source, and operates without manual assistance from the user.

  • Patent number: 5509162
    Abstract: A cylindrical brush of the type utilized in an industrial type sweeper is retained on one end by an idler broom arm. The idler broom arm is hingedly connected to a member transverse to the brush such that the broom arm swings outwardly from the brush to effect a brush change as the broom arm is pivotally retained. A latch retains the arm in its closed position. The hinge is located radially behind and axially outwardly relative to the brush. This offset location of the hinge creates an inward biasing of the broom arm during forward travel of the sweeper to retain the brush between the idler broom arm and the driven broom arm on the opposite side of the brush.
