  • Patent number: 5428854
    Abstract: A replaceable bristle ring for removable attachment to a swimming pool cleaner, such bristle ring having bristles secured along it and projecting downwardly to terminate in bristle ends adapted to support the pool cleaner on a surface to be cleaned and means facilitating attachment with respect to the pool cleaner housing. A preponderance of the bristles are preferably inclined along lines which are skew lines with respect to the axis of the ring, such that vibration causes movement of the pool cleaner along a swimming pool bottom surface. A preferred replaceable ring has an annular surface with features for interengagement with another bristle ring.

  • Patent number: 5426806
    Abstract: A sport grip cleaning unit to be used at the location of the sporting activity. The cleaning unit consists of a vending operation under the control of the user. The unit consists of a two compartment cabinet whereby the user is able to control the cleaning action of the unit by the insertion of the sporting apparatus handle into the unit whereby the grip handle butt depresses a micro-switch activating the cleaning brushes. This action also causes the cleaning fluid pump to activate whereby the cleaning fluid floods the cleaning area to lubricate and flush accumulated grime, grit, and oils into the drain system where it is filtered and recycled. Thus the grip is restored to its desired tacky, firm hold condition. The sport grip cleaning unit includes a cleaning fluid reservoir that is removable from the unit for replacement with a new reservoir of cleaning fluid. In this manner, the cleaning unit is self-contained and can be easily serviced.

  • Patent number: 5426807
    Abstract: A tube cleaning apparatus for tubes and pipes installed in power plant and similar industrial equipment utilizes a rotating brush assembly fitted to one end of a rotary cable encased in a protective casing and driven at its other end in clockwise and counterclockwise rotation by a reversible motor. The invention provides a drive unit fitted with a plurality of drive rollers for engaging the protective casing and propelling the casing, cable and brush assembly at a high rate of speed into and out of each tube being cleaned. A control system for the drive unit enables the operator to manipulate the reversible motor by issuing pulses to actuate switches controlling on/off and direction of rotation of the motor. An arresting device provides for stopping forward progress of the brush assembly as it reaches the end of each tube being cleaned.

  • Patent number: 5421053
    Abstract: A coupling for removably affixing a brush to a rotatable drive shaft includes a drive hub affixed to the drive shaft, in which an axial projection having a cam surface is disposed on either the drive hub or the brush. The other of the hub and the brush defines a recess for accepting the projection and has a spring retainer affixed thereto. The projection and recess have an interfitting spline connection for preventing relative rotation between the drive hub and the brush. The cam surface is adapted to elastically spread the retainer to allow-the projection to be inserted within the recess. The retainer thereafter engages the shelf surface to prevent removal of the projection from the recess. The spring retainer is provided with tabs for elastically spreading the retainer to disengage the shelf surface and allow the brush to be easily removed from the drive hub.

  • Patent number: 5418997
    Abstract: A sanitary sewer root clean out tool for use with a plumber's snake is formed by an elongated helical member having a forward compacted root penetrating end portion supporting a pair of laterally pivoting blades which are retracted during forward movement of the tool and expand laterally in a root cutting action when moved rearwardly. A root cutting assembly transversely surrounds an intermediate portion of the elongated helical member and is angularly rotated thereby by forward and rearward movement of the helical member relative to the cutting assembly to sever roots surrounding the helical member by blades radially projecting outward from the periphery of the helical member as the latter is longitudinally reciprocated.

  • Patent number: 5416942
    Abstract: A motorized anti-plaque toothbrush comprises a handle (1) at one end of which is a cleaning/massaging head (3), in particular a brushing head, which rotates about an axis which is approximately perpendicular to the longitudinal axis of the handle (1) and is turned with a continuous one-way rotary motion or with a reciprocating rotary motion by a motor, preferably an electric motor, housed in the handle (1). According to the invention, the cleaning/massaging head (3) is composed of at least two separate cleaning/massaging tool parts (4, 5) that are supported coaxially with respect to each other in such a way that they can rotate relative to each other, being turned in mutually opposite directions in the case of continuous one-way rotation and in phase opposition to each other in the case of reciprocating rotation.

  • Patent number: 5414888
    Abstract: An improved plumbers' tool of the type employing a helically wound coiled spring which is controllably inserted into waste lines to remove blockages. In operating the tool of the invention, a storage drum from which the clean-out spring is payed out is rotated, usually by a small electric motor, and the spring is clamped in a chucking mechanism so as to rotate with the housing. The improvement of the present tool resides in the provision of a unique actuating mechanism which provides a substantial mechanical advantage that enables the operator, using only one hand to grip a forwardly positioned stationary handle with the fingers and move a pivotally movable, rearwardly positioned handle with the heel of the hand to cause the chucking mechanism to positively engage the coiled spring in a manner to prevent slippage even under severe torque loading conditions.

  • Patent number: 5412826
    Abstract: A turbine driven underwater pool cleaner is disclosed having a housing to which is attached a hose providing a source of suction. The suction functions to draw debris into and through the housing via an opening at the bottom surface of the housing. A rotatable turbine is provided in the flow path of the fluid being drawn through the housing. A pair of wheels are provided which are mounted both for rotation and translation with respect to the housing. A pair of shafts extend from and are driven by the turbine. A radial projection is provided at the end of each shaft. During each revolution of the shaft, the radial projection provides both a rotational and a translation force on the wheel for driving the cleaner in a sure manner about the pool surface. Two alternate approaches are disclosed for steering the cleaner. In one approach, the drive to one of the wheels is selectively disengaged. In another embodiment, the device is steered by placing a torque on the suction hose.

  • Patent number: 5412829
    Abstract: To scrub adjacent parallel grout lines on a tile floor simultaneously, a long handle is attached to a base which is wider than the space between adjacent grout lines. Two or more long narrow scrubbing elements are adjustably mounted on the base with the long sides parallel to one another. They are spaced apart to correspond to the spacing between tiles and locked in position. When they are moved back and forth in a scrubbing motion, they tend to remain in the depressed grout lines so they are self-guiding. All the scrubbing effort is directed to the grout lines which tend to accumulate dirt more than the elevated, impervious tile surface. The scrubbing elements may be bristle brushes, foam or fibrous scrubbing material. An electric motor driven embodiment is shown with rotary brushes adjustably mounted on a rotary shaft.
