Abstract
Abstract A device, including a mixing chamber, that is adapted to be positioned in a water line between the water source and a dispersion mechanism such as a sprinkler. The device includes a manually operable mechanism for introducing a measured amount of chemical into a normally fluid-tight mixing chamber. The inflow of water is simultaneously dispersed into and agitated within the mixing chamber and the outflow of water restricted so that undissolved chemicals are not allowed to flow out with the irrigation water.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
A device for mixing a soluble substance with a flowing stream of water, comprising: a mixing chamber of circular cross section having an upper section and lower section, said upper section including a concave depression, terminating in a circular opening for forming a pre-induction holding zone for said soluble substance, said concave depression including indicia displayed thereon for measuring the quantity of flowable substance therein, means for introducing said soluble substance into said mixing chamber including within said mixing chamber a depressible conically shaped element outwardly spring biased to seat in fluid-tight engagement with the opening in said concave depression and allow introduction of said soluble substance into said mixing chamber only when said conically shaped element is depressed; means in said lower section for supplying liquid to said mixing chamber, said liquid supplying means including a nozzle located adjacent one side of said chamber, said nozzle having a plurality of openings of lesser total cross section than said liquid supplying means for distorting the flow of said liquid within said mixing chamber to cause agitation thereof and thereby enhance the rate of dissolution of said soluble substance in said liquid; and means in said lower section for removing said substance-containing water from said mixing zone, said removing means located adjacent a side of said chamber diametrically opposite said nozzle.

Claim 3
Dependent Claim
27 words
A device in accordance with claim 1 wherein said removal means includes a strainer having openings therein adapted to prevent egress of solid particles of soluble substance.
Claim 4
Dependent Claim
29 words
A device in accordance with claim 1 wherein at least one of said plurality of openings is formed to direct liquid tangentially to the wall of said mixing zone.
Claim 5
Dependent Claim
29 words
A device in accordance with claim 1 wherein at least one of said plurality of openings is formed to direct liquid inwardly of the wall of said mixing zone.
