Mounting device for a garbage disposal
First Claim
1. A tool for mounting a snap ring to a sink flange for supporting a garbage disposal below a sink, said sink having a top surface, a bottom surface and a sink drain opening having a central axis and extending between said surfaces, said sink flange having a flange lip supported by said top surface about said sink drain opening and a flange body having a cylindrical shape for extending coaxially through the drain opening to a lower end having an annular groove for receiving said snap ring, said tool comprising:
- a) a keeper for temporarily securing a platform adjacent said flange body lower end below said sink bottom surface,b) said keeper including a head portion for engaging said sink flange adjacent said top surface of said sink and a leg portion extending from said head portion through said flange body for engagement with said platform,c) said platform including loading means, biasing means and a connector,d) said loading means being arranged to hold said snap ring in an expanded condition for insertion in said annular groove,e) said biasing means being operable to displace said snap ring from said loading means into said annular groove,f) said connector being operable to releasably connect said platform to said leg portion whereby said head portion temporarily secures said platform adjacent to and axially aligned with said lower end of said flange body for axial movement of said snap ring into said annular groove upon operation of said biasing means.

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.

14. A tool for mounting a support ring assembly with a snap ring to a sink flange for supporting a garbage disposal below a sink, said sink having a top surface, a bottom surface and a sink drain opening having a central axis and extending between said surfaces, said sink flange having a flange lip supported by said top surface about said sink drain opening and a flange body having a cylindrical shape for extending coaxially through the drain opening to a lower end having an annular groove for receiving said snap ring, said tool comprising:
-
a) a keeper for temporarily securing a platform adjacent said flange body lower end below said sink bottom surface, b) said keeper including a head portion for engaging said sink flange adjacent said top surface of said sink and a leg portion extending from said head portion through said flange body for engagement with said platform, c) said platform including a central platform opening for receiving said leg portion, an annular loading shoulder, a snap ring biasing member, a ring assembly mount and a connector for engaging said leg portion, d) said annular loading shoulder having an axially extending wall connected to a radially extending wall, said snap ring being mounted on said shoulder in an expanded condition for insertion in said annular groove, e) said snap ring biasing member being operable from a normally retracted position to an extended position to displace said snap ring from said shoulder into said annular groove, f) said support ring assembly mount comprising angularly spaced members for engaging and supporting said ring assembly on said platform as the ring assembly is positioned about said flange body and secured in position by inserting said snap ring in said annular groove, and g) said connector including a connector opening for receiving and releasably engaging said leg portion whereby said keeper temporarily secures said platform adjacent to and axially aligned with said lower end of said flange body for axial movement of said snap ring into said annular groove upon operation of said biasing member. - View Dependent Claims (15, 16, 17, 18)
