Edward Richards - Davie FL, US

International Classification:

A47L 7/00

US Classification:

15320

Abstract:

A surface cleaner, comprising a tank having a fluid-filled part and an air-filled part; a vacuum pump; a fluid pressure pump; a cleaning head having a cleaning chamber and a vacuum chamber, the cleaning chamber forming a cavity bounded by a surface to be cleaned, the vacuum chamber having an inlet lip at the periphery of the cleaning chamber; jet nozzles mounted within the cleaning chamber; wherein the pressure pump draws fluid from the tank and ejects it into the cleaning chamber through the nozzles; wherein the vacuum pump maintains a low pressure in the air-filled part of the tank and a high pressure in the cleaning chamber; and wherein the inlet lip is in fluid communication with the air-filled part of the tank portion whereby fluid ejected into the cleaning chamber is drawn into the inlet lip and returned to the tank.

Inventors:

Edward M. Richards - Davie FL, US

International Classification:

B66F 15/00

Abstract:

Long-handled lever rotates lower cam surface about an upper pivot axle between 2 spaced-apart fixed wedge-bodies which are further held apart by a lower pivot axle. A movable wedge-body between the fixed bodies rotates on the lower axle due to a cam follower actuated by the lever cam surface. At rest without cam action, the 3 acute-angle-shaped wedge feet form a composite wedge forced into the pry space between beams, etc. With lever rotations, the movable wedge foot moves away from the fixed wedge feet by rotation about the lower pivot axle. The method mounts fixed wedges on first and second pivots. Counterclockwise movement leverages the lever about the first pivot, rotating a convex cam over a concave cam follower on an upper ankle of the movable wedge causing clockwise rotation of the movable wedge about the second pivot resulting in separation of fixed versus movable acute wedge surfaces.
