Title
(EN) Floor coating machine
Abstract
(EN)

A machine for applying a liquid coating material such as floor wax, carpet protector or sealer, to a flat surface, such as a floor or the like, includes a first sealed vessel for containing compressed gas and a second sealed vessel for containing the liquid. A pressure regulator is provided for maintaining a predetermined positive pressure head within the liquid-containing vessel, and associated conduit is provided for conveying gas at the predetermined positive pressure to the second vessel. The machine includes at least one spray nozzle and a conduit for conveying liquid from the second vessel to the at least one spray nozzle. The spray nozzle is height adjustable to insure that the sprayed material is uniformly applied to the floor as a relatively light coat without having to spread the applied material. The vessels, conduit, pressure regulator and at least one nozzle are preferably supported on a wheeled cart to provide a machine which can apply a liquid coating uniformly to a large floor area in a very rapid manner without having to stop to refill the vessels, and without requiring any motors or other electrical equipment which need to be connected to an electrical outlet during operation of the apparatus. A method according to the invention includes the steps of supplying a compressed gas to a first sealed vessel, supplying a liquid to a second sealed vessel, withdrawing compressed air from the first vessel, and conveying the gas to the second vessel by use of a pressure regulator to maintain the second vessel at a predetermined positive pressure, and conveying liquid from the second vessel to at least one spray nozzle at the constant predetermined pressure, whereby liquid is discharged from the at least one spray nozzle at a substantially constant rate.
