Abstract

Abstract A mop assembly is provided to uniformly and controllably apply and distribute liquids to the surfaces of exposed floors. A tank having a teardrop shape in the transverse plane maintains a low center of gravity and a relatively thin cross-section which along with the handle passing centrally through the tank permits the mop assembly to be used under low obstructions. Clamps around shouldered openings at either end of the tank through which the handle passes seal the tank. A control rod inside a sleeve passing through the tank permits operation of a control valve on a discharge port at the bottom of the tank. One head attachable to the mop assembly consists of a plate to which a porous pad is attached. The liquid is fed through tubing connected to the discharge port to dispense liquid through the pad. Another head consists of an elongated plate having an attached fiberous pad and a liquid distribution header which has a multiplicity of holes along one edge. A resilient connection secured between the head and the handle biases the head to fully contact the floor.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 161 words
A mop assembly for distributing liquids on a floor area comprising an elongated handle having an upper end to be grasped by an operator, an elongated mop head pivotally attached to the lower end of said handle, a tank carried by and surrounding a portion of said handle, said handle extending through said tank centrally thereof, means on said tank sealingly securing said tank to said handle portion, said tank being generally rectangular in horizontal section and having its major axis essentially parallel to the axis of said mop head, said tank having an upper filler opening and a lower outlet opening, a flexible conduit connecting said outlet opening to said mop head, a valve in said conduit, a sleeve extending through said tank from top to bottom generally parallel to said handle and valve operator means connected at one end to said valve and extending through said sleeve, the opposite end of said operator means projecting exteriorally of the tank.
Claim 2
Dependent Claim 161 words
A mop assembly for distributing liquids on a floor area comprising an elongated handle having an upper end to be grasped by an operator, an elongated mop head pivotally attached to the lower end of said handle, a tank carried by and surrounding a portion of said handle, said handle extending through said tank centrally thereof, means on said tank sealingly securing said tank to said handle portion, said tank being generally rectangular in horizontal section and having its major axis essentially parallel to the axis of said mop head, said tank having an upper filler opening and a lower outlet opening, a flexible conduit connecting said outlet opening to said mop head, a valve in said conduit, a sleeve extending through said tank from top to bottom generally parallel to said handle and valve operator means connected at one end to said valve and extending through said sleeve, the opposite end of said operator means projecting exteriorally of the tank.
Claim 3
Dependent Claim 245 words
A mop assembly for the rapid placement of treatment liquids on large floor areas, both unobstructed and obstructed under furniture, comprising, a handle having an upper and lower end, a mop head pivotally attached to the lower end of the handle, having a front and rear edge, means for biasing the front edge of the mop head relative to the handle to direct the rear edge of the mop head against the floor when the mop handle is lowered to pass the mop head under furniture, a tank, for carrying a floor surface treatment liquid, mounted on the handle and having top and bottom openings to permit the handle to pass centrally through the tank, and also having a discharge port in a lower end and a filling port, and having overall dimensions to permit use of the mop assembly in low clearance areas, such as floor areas located under furniture, means for distributing the floor treatment liquid on the floor, a control valve located between the tank discharge port and the distribution means and having an actuating lever, to control the liquid flow rate from the tank, a sleeve passing through the tank from above to below, and a valve control rod passing through the sleeve within the tank for protection of the valve control rod, and having its lower end connected to the actuating lever, so the control valve is actuated by pushing and pulling the upper end of the valve control rod.
Claim 4
Dependent Claim 245 words
A mop assembly for the rapid placement of treatment liquids on large floor areas, both unobstructed and obstructed under furniture, comprising, a handle having an upper and lower end, a mop head pivotally attached to the lower end of the handle, having a front and rear edge, means for biasing the front edge of the mop head relative to the handle to direct the rear edge of the mop head against the floor when the mop handle is lowered to pass the mop head under furniture, a tank, for carrying a floor surface treatment liquid, mounted on the handle and having top and bottom openings to permit the handle to pass centrally through the tank, and also having a discharge port in a lower end and a filling port, and having overall dimensions to permit use of the mop assembly in low clearance areas, such as floor areas located under furniture, means for distributing the floor treatment liquid on the floor, a control valve located between the tank discharge port and the distribution means and having an actuating lever, to control the liquid flow rate from the tank, a sleeve passing through the tank from above to below, and a valve control rod passing through the sleeve within the tank for protection of the valve control rod, and having its lower end connected to the actuating lever, so the control valve is actuated by pushing and pulling the upper end of the valve control rod.
