A chemical dispensing apparatus includes a housing that is connectable to a source of water, such as a standard garden hose, and an internal space in which is disposed a rotatable container containing a quantity of chemical concentrate to be mixed with the source of water as it flows through the housing and is dispensed from the housing from a sprinkler head or misting nozzle. The flow of water through the housing is directed to imping vanes on the rotatable container, such that the container is rotated as water flows through the housing. In an alternative embodiment, the vanes are replaced with an electric motor. Rotation of the container cause the chemical concentrate to dissolve which is then mixed with the water before it is dispensed through the sprinkler or mister.

1. A chemical dispensing apparatus for use in delivery of a treatment solution to a lawn, the apparatus comprising: a main fluid supply passage configured for connection to a pipe system carrying water under pressure;a housing including an internal cavity, an end having an opening into said internal cavity, a discharge port and a drain port;a fluid discharge passage connecting said discharge port and said internal cavity;an internal fluid supply passage connecting said main fluid supply passage to said internal cavity;a drain passage connecting said internal cavity to said drain port;a float valve disposed across said drain passage and across said internal fluid supply passage, said float valve including a float that is displaced by a fluid flow through said internal fluid supply passage from said main fluid supply passage from a first position where said drain passage is open and said internal fluid supply passage is sealed by said float to a second position where said internal fluid supply passage is open and said drain passage is sealed by said float, said float returning to said first position when said fluid flow is stopped;a container removably disposed within said internal cavity and supported for rotation therein about a vertical axis, said container configured for the reception of a chemical concentrate, said container having vanes extending the circumference thereof;a nozzle disposed across said internal fluid passage and arranged to direct a jet of water at said vanes, the impingement of said jet of water on said vanes causing said container to rotate about said vertical axis; anda lid removably attached to said housing, said lid sealing said opening into said internal cavity when attached to said housing. 2. The apparatus of claim 1, wherein said main fluid supply passage is configured at opposite ends thereof for inline connection to the pipe system carrying water under pressure. 3. The apparatus of claim 1, wherein said discharge fluid passage, said drain passage and said internal fluid supply passage are each defined by said housing. 4. The apparatus of claim 1, further comprising: a sprinkler head connected to said discharge port. 5. The apparatus of claim 1, further comprising: a bypass fluid passage connecting said main fluid supply passage to said fluid discharge passage; anda control valve connected to said main fluid supply passage, said fluid bypass passage and said internal fluid supply passage and operable to selectively permit or preclude the flow of fluid from said main fluid supply passage through said bypass passage and said internal fluid supply passage. 6. The apparatus of claim 5, further comprising: a flap valve operable to fluidically connect said fluid discharge passage to said discharge port and seal said fluid bypass passage from said discharge portion when a fluid flows through said fluid discharge passage or to fluidically connect said bypass passage to said discharge portion and seal said fluid discharge passage from said discharge portion when a fluid flows through said bypass passage. 7. The apparatus of claim 1, wherein said vanes are disposed on said container such that when said container is disposed in said internal cavity in a first position said nozzle is not disposed to direct said fluid jet at said vanes, and such that when said container is disposed in said internal cavity in a second position said nozzle is disposed to direct said fluid jet at said vanes. 8. The apparatus of claim 1, further comprising: an internal reservoir tank connected inline to said drain passage intermediate said float valve and said drain port to receive and hold a quantity of fluid flowing through said drain passage from said internal cavity;a one-way valve connected to said drain passage at an upstream end from said internal reservoir tank;a second drain valve connected to said drain passage at a downstream end from said internal reservoir tank; anda siphon tube connecting said internal reservoir tank and said fluid discharge passage, wherein a fluid flow through said fluid discharge passage results in a vacuum on said siphon tube that causes fluid contained within said internal reservoir tank to be drawn into said fluid flow. 9. The apparatus of claim 8, wherein said main fluid supply passage is configured at opposite ends thereof for inline connection to the pipe system carrying water under pressure. 10. The apparatus of claim 8, wherein said discharge fluid passage, said drain passage and said internal fluid supply passage are each defined by said housing. 11. The apparatus of claim 8, further comprising: a sprinkler head connected to said discharge port. 12. The apparatus of claim 8, further comprising: a bypass fluid passage connecting said main fluid supply passage to said fluid discharge passage; anda control valve connected to said main fluid supply passage, said fluid bypass passage and said internal fluid supply passage and operable to selectively permit or preclude the flow of fluid from said main fluid supply passage through said bypass passage and said internal fluid supply passage. 13. The apparatus of claim 12, further comprising: a flap valve operable to fluidically connect said fluid discharge passage to said discharge port and seal said fluid bypass passage from said discharge portion when a fluid flows through said fluid discharge passage or to fluidically connect said bypass passage to said discharge portion and seal said fluid discharge passage from said discharge portion when a fluid flows through said bypass passage. 14. The apparatus of claim 8, wherein said vanes are disposed on said container such that when said container is disposed in said internal cavity in a first position said nozzle is not disposed to direct said fluid jet at said vanes, and such that when said container is disposed in said internal cavity in a second position said nozzle is disposed to direct said fluid jet at said vanes.
