Multinozzle spraying apparatus

Claim 1

A multinozzle spraying apparatus comprising: a spindle having a fluid passageway therethrough and having a seating surface on the forward end thereof and a hose connection on the rearward end thereof, said seating surface including a flow port therein communicating with said passageway; a turret member rotatably secured on the forward portion of said spindle having a multiport seating surface formed therein for matingly engaging the seating surface of said spindle and including a plurality of fluid passages each extending from one of the ports in said multiport seating surface to one of a plurality of threaded recesses disposed in the external surface thereof, said ports in said turret member being spaced apart from each other and positioned with respect to the flow port in said spindle so that the turret member may be rotated to bring the ports therein into selective registration with the flow port in said spindle or to shut off flow therethrough; means for indicating the pressure of the fluid flowing through any one of said fluid passages in said turret member comprising: a threaded recess disposed in said turret member; a pressure passage disposed in said turret member communicating said threaded recess with the forward end of said spindle; said spindle including a second port in the seating surface thereof connected to the forward end thereof by a pressure passage; said turret member including a second plurality of ports in the seating surface thereof, each communicated with one of said fluid passageways therein by a pressure passage, said second ports in said turret member being positioned with respect to the second port in said spindle so that when said flow port in said spindle is aligned with a port in said turret member, one of said second ports in said turret member is aligned with said second port in said spindle; and a pressure indicator threadedly secured in said threaded recess; means for maintaining the seating surface of said spindle in mated engagement with the multiport seating surface of said turret member attached to said turret member and to said spindle; and a plurality of spray nozzles having different spray characteristics each threadedly secured in one of said threaded recesses in said turret member.
