  • Patent number: 7185408
    Abstract: A tool for installing a garbage disposal to a sink flange extending below a sink includes a keeper and a platform. The keeper includes a head portion for engaging the sink flange above the sink and a leg portion extending along the sink axis through the sink flange. The platform carrying disposal mounting rings is releasably engaged with the leg portion below the sink to position it adjacent to and aligned with the end of the sink flange body. A snap ring is biased from the platform onto the flange body and into the annular groove in the flange body to trap the back-up ring and mounting ring on the flange body below the sink. The platform is disengaged from the leg portion and the tool is removed so that the disposal may be secured to the mounting ring in a known manner.

  • Patent number: 4819459
    Abstract: A front loading cleaning machine may be operated in a normal manner by opening the front door and loading clothes to be washed. When servicing is required, the entire unit may be tipped forwardly about 90 degrees so that the front door is next to the floor. This makes the rear of the machine unit uppermost and exposes the drive mechanism mounted thereon. The drive mechanism may then be readily serviced because the mechanically moving parts are exposed on the upper portion of this machine unit. After servicing, the machine may readily be tipped back to its upright position, ready for normal operation. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
