Abstract

A tool is used to elevate and hold a garbage disposer against a sink fixture during removal and/or installation of a garbage disposer. The tool includes a flat base including a notch opening through a corner of a rectilinear base to allow an electric cord to pass around the tool. A flat load supporting platform includes a similar notch. A screw jack force applying mechanism allows the platform to be raised relative to the base. The tool works equally well with the base down or with the platform down so the user doesn'"'"'t have to turn the tool over for it to work.

Claims

1. A disposer installation tool comprising

a base having a flat load bearing surface having at least one notch communicating with a side of the base to receive wiring leading from the disposer when the base engages a disposer,

a flat load supporting platform having a load bearing surface having at least one notch communicating with a side of the platform to receive wiring leading from the disposer when the platform engages the disposer whereby the base and load supporting platform operate with either one engaging the disposer and the other one engaging an underlying surface, and

a screw jack mechanism for moving the base and platform relative to each other including

a tube extending perpendicular to the base and providing a free end having an abutment,

a threaded rod connected to the load supporting platform adjacent a center thereof, and

a nut, on the threaded rod, abutting the abutment of the tube so that rotation of the nut bears against the tube and moves the platform relative to the base,

the installation tool being operative with the base being supported by an underlying surface and a load on the platform and with the platform being supported by an underlying surface and a load on the base.

2. The disposer installation tool of claim 1 wherein the platform comprises a blind passage adjacent the center thereof, a second nut in the blind passage and affixed to the platform, the threaded rod being threaded into the second nut and extending perpendicularly from the platform.

3. The disposer installation tool of claim 2 wherein the second nut is adhesively affixed to the platform.

4. The disposer installation tool of claim 2 wherein the base provides a passage near a center of the base and the tube is inserted into the passage.

5. The disposer installation tool of claim 4 wherein the passage is a blind passage and wherein the tube is friction fit in the blind passage provided by the base so the tube and threaded rod may be removed from the base and the platform to lie flat during shipment.

6. The disposer installation tool of claim 1 wherein the nut provides an exterior of polygonal configuration free of lever extensions and of a size to be manually turned against a load of twenty pounds on the platform.

7. The disposer installation tool of claim 1 wherein the base and platform are of rectilinear configuration and the notch opens through a corner.

8. The disposer installation tool of claim 1 wherein the screw jack mechanism provides a first mechanical advantage when the load supporting platform carries a disposer and a second equal mechanical advantage when the base carries a disposer of equal weight.

9. The disposer installation tool of claim 1 wherein the flat load bearing surface of the base being free of projections extending therefrom and the load bearing surface of the platform being free of projections extending therefrom.
