Abstract:
1. A hand-held dispenser apparatus for controlling the flow rate of water therethrough and for controlling the metering of a liquid chemical into the water passing through the apparatus, comprising: a body member; said body member including a generally horizontally disposed first body portion having first and second sides, an inlet end, a discharge end, and a first fluid passageway, having inlet and discharge ends, extending between said inlet and discharge ends of said first body portion; said inlet end of said first fluid passageway adapted to be secured to a source of water under pressure; said first body portion having a transversely extending spool opening formed therein which extends between said first and second sides thereof and which communicates with said first fluid passageway; a spool member mounted in said spool opening and having an inlet end, an outlet end, an upper end, a lower end, and first and second sides; said spool member having a second fluid passageway extending between its said inlet and outlet ends which communicates with said first fluid passageway; said spool member having a third fluid passageway formed therein which extends from said second fluid passageway to said lower end of said spool member; said body member also including a vertically extending second body portion, having upper and lower ends and first and second sides; said second body portion having a transversely extending, horizontally disposed cylindrical bore, having first and second ends, formed therein below said spool opening which extends between said first and second sides thereof; said body member having a fourth fluid passageway formed therein which extends downwardly from said spool opening to said cylindrical bore; said second body portion having a fifth fluid passageway formed therein which extends from said cylindrical bore to said lower end thereof; said fifth fluid passageway being in communication with a source of liquid chemical; a cylindrical chemical metering valve, having first and second ends, selectively rotatably mounted in said cylindrical bore and being rotatable between first and second positions; said metering valve having radially spaced-apart first and second transversely extending metering passageways formed therein, each of which has an inlet end and a discharge end; said first and second metering passageways permitting different chemical flow rates therethrough; when said metering valve is in its said first position, said inlet end of said first metering passageway is in fluid communication with said fifth fluid passageway and said discharge end of said first metering passageway is in fluid communication with said fourth fluid passageway; when said metering valve is in its second position, said inlet end of said second metering passageway is in fluid communication with said fifth fluid passageway and said discharge end of said second metering passageway is in fluid communication with said fourth fluid passageway; wherein an elongated first valve handle is secured to said first end of said metering valve and wherein an elongated second valve handle is secured to said second end of said metering valve; said first and second valve handles are radially offset with respect to one another; wherein a first stop is provided at said first end of said spool member which is in rotational path of said first valve handle and wherein a second stop is provided at said second end of said spool member which is in the rotational path of said of said second valve handle.
