Liquid chemical applicator for treatment of a horizontal surface

Claim 1

A liquid chemical applicator for treatment of a horizontal surface which comprises: (a) a pair of front wheels; (b) a frame having an axle, an extension arm and a control handle, said axle extending between said front wheels, said extension arm rearwardly projecting transversely from center of said axle bending upwardly therefrom with, said control handle at distal end of said extension arm; (c) a rear wheen rotatably connected to bottom of said extension arm rearwardly of said front wheels whereby said rear wheel is manually steered by an operator holding onto said control handle; (d) means for applying a uniform coating of said liquid chemical onto said horizontal surface from said applicator which is controlled by said operator, said applying means including a drum for holding said liquid chemical therein and a pump fluidly connected to said drum for removing said liquid chemical from said drum and bringing said liquid chemical to said applicator at a desired pressure and means for directing flow of said liquid chemical through said applicator and a pair of manifolds mounted along said axle each of said manifolds having a plurality of spray nozzles and means for controlling pressure of said liquid chemical fluidly connected between said directing means and said spray nozzles of said manifolds so that said spray nozzles will apply a plurality of overlapping sprays of said liquid chemical at a constant height a constant pressure and a proper angle onto said horizonal surface; (e) a storage basket mounted to top of said extension arm between said front wheels and said rear wheel; and (f) a wind shield mounted onto said axle over said manifolds to help keep spray pattern constant and prevent said liquid chemical from blowing away.
