  • Patent number: 12151391
    Abstract: A coping cut machine can include a workpiece platform having a support surface for receiving a workpiece support surface. The coping cut machine can have first and second rotary cutting devices, each supporting at least one knife, and at least one workpiece alignment member supported by the workpiece platform for aligning a workpiece supported by the workpiece platform relative to at least one of the first and second rotary cutting devices. In response to sliding the workpiece along the at least one workpiece alignment member and during rotation of at least one of the first and second rotary cutting devices, the at least one knife operates to perform a coping cut on an end of the workpiece. The first and second rotary cutting devices can optionally be rotated in opposite directions to cut either end of a workpiece.

The rotary cutting device can optionally be operated bi-directionally to cut either end of a workpiece. The rotary cutting device can comprise a modular rotary cutting assembly having a keyed profile portion received in a keyed profile aperture of a drive wheel, and that is removable from the coping cut machine.

  • Patent number: 7048805
    Abstract: A dual mode carpet cleaning method is capable of being used in both a deep cleaning mode and a fast drying surface cleaning mode. The method utilizes a carpet cleaning apparatus that provides selective communication with different sets of cleaning jets. One set of cleaning jets is operated to deliver a first cleaning solution that penetrates deeply into a carpet in the deep cleaning mode. A second set of cleaning jets is operated to deliver a lower flow rate of a second cleaning solution that does not penetrate as deeply into the carpet and dries quickly. The method involves manually operating a valve on the apparatus to selectively communicate a source of cleaning fluid of the apparatus with one of the first set of cleaning jets and the second set of cleaning jets, and discharging the cleaning liquid from the selected one of the first set of cleaning jets and second set of cleaning jets onto a carpet to be cleaned.

  • Publication number: 20050050645
    Abstract: A dual mode carpet cleaning machine capable of being used in both a traditional deep cleaning mode and a fast drying surface cleaning mode. A selection mechanism provides selective communication with different sets of application jets. One set of application jets delivers a first cleaning solution that penetrates deeply into a carpet. After agitation with a scrub brush the device removes the cleaning solution and unwanted soil through a vacuum nozzle. The other set of jets delivers a lower flow rate of a second cleaning solution that does not penetrate deeply into the carpet. In addition, a novel cleaning solution is disclosed for use with the machine in differing concentrations, depending on the desired application.

The carpet cleaning solutions dry more quickly when applied to carpet than previous solutions; the combined performance of the system displays similar cleaning efficiencies to previous carpet cleaning machines but obtains significantly reduced drying times.

  • Patent number: 6568024
    Abstract: The invention is a cleaning tool housing assembly and a replaceable cleaning assembly. The manifold, in combination with a fluid intake element, also delivers fluid (under pressure through holes in the manifold located in a longitudinal channel) to a sponge. Two spaced apart fluid barriers are longitudinally disposed in the sponge. As fluid is introduced into the center of the sponge, between the fluid barriers, the fluid travels toward the opposite surface of the sponge. The fluid is prevented from traveling laterally due to the fluid barriers. As vacuum pressure, negative pressure, is exerted on the outer portions of the sponge (on each side of the fluid barriers), fluid is pulled back through the sponge, through the manifold and through the nozzles into the hollow housing body.
