Abstract:
1. A hand-held dispenser apparatus for controlling the flow rate of water therethrough and for injecting 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, and a discharge end; said body member also including a generally vertically disposed second body portion extending downwardly from said first body portion; said second body portion having a lower end adapted to be secured to a liquid container; said first body portion having a generally horizontally disposed first body member which extends inwardly from said inlet end of said body member toward said discharge end thereof; said first body member having an inlet end and a discharge end; said first body member having a horizontally disposed first passageway formed therein which extends from said inlet end towards said discharge end thereof; said first passageway having an inlet end and a discharge end; said inlet end of said first fluid passageway adapted to be placed in communication with a source of water under pressure; said first body portion having a generally vertically disposed second body member positioned at said discharge end of said first body member with said second body member having upper and lower ends; said second body member having a cylindrical chamber formed therein which has an inlet end and a discharge end; said second body member having a horizontally disposed annular valve seat molded therein above its said inlet end; said valve seat having a lower inlet side and an upper discharge side; said lower inlet side of said valve seat being in communication with said first passageway; said upper discharge side of said valve seat being in communication with said chamber; said lower inlet side of said valve seat having a lamer diameter than the diameter of said upper discharge side of said valve seat; a vertically movable first valve means selectively vertically movably mounted in said chamber; said first valve means including a valve member and a valve stem secured to said valve member which extends upwardly therefrom through said valve seat and said chamber; said valve member of said first valve means having a truncated conical shape; said first valve means being vertically movable between a lower position to an upper position; said valve member of said first valve means being received by said valve seat to close said valve seat when said first valve means is in its said upper position; said valve member when said first valve means is in its said lower position, permitting the flow of water from said first passageway, through said valve seat, and upwardly into said chamber; a valve actuating lever pivotally secured to said first body portion which is operatively connected to the upper end of said valve stem; said lever being pivotally movable from an upper “off” position wherein said first valve means is in its said upper position to a lower “on” position wherein said valve member is unseated from said valve seat; said discharge end of said first passageway being positioned below said lower inlet end of said valve seat so that the water under pressure in said first passageway exerts pressure against the lower end of said valve member of said first valve means when said first valve means is in said upper position to assist in maintaining said first valve means in its said upper position and so that water under pressure in said first passageway exerts pressure against the upper end of said valve member of said first valve means when said first valve means is in said lower position; said first body portion having a horizontally disposed second passageway formed therein which extends from said chamber, above said valve seat, towards said discharge end of said first body portion; said first body portion having a third body member positioned at the downstream side of said second body member; said third body member having a transversely extending spool opening formed therein; said third body member having a third passageway which extends from said spool opening to said second passageway; said third body portion having a fourth passageway extending from said spool opening towards said discharge end of said body member; said third and fourth passageways being in alignment with each other; a spool valve selectively rotatably mounted in said spool opening; said spool valve having at least two passageways formed therein which have different diameters; said spool valve being selectively rotatable so that either of said two passageways therein may be placed in communication with said third and fourth passageways; said first body portion having an elongated fifth passageway extending from said spool opening to said discharge end of said body member; said body member having a sixth passageway formed therein which extends downwardly from said fifth passageway to said lower end of said second body portion so as to be in communication with the liquid in the liquid container; the passage of water through said fifth passageway to said discharge end of said body member, when said first valve means is in its said open position drawing liquid from the liquid container upwardly through said sixth passageway for mixing with the water passing through said fifth passageway.
