A new use of the apparatus for dispensing chemicals such as insecticides and fertilizers by means of a garden hose is disclosed. In earlier applications the use of a spherical feeder capsule in an “intermediate-velocity chamber”was disclosed wherein the spherical shape provided uniformity of feeding by reason of its random movement and rotation in the chamber. In the new use described, the spherical shape may provide a decidedly non-uniform rate of feeding; and there may be a lesser degree of freedom of the feeder within the chamber compared to the earlier-claimed uses. In the preferred embodiment a water supply is connected through a hose to a chamber such as the “Fluidic Lawn Feeder”produced by Acme Burgess Inc. From the chamber a second piece of hose extends to a pistol-grip nozzle of the well-known type whereby an operator may quickly turn the water on and off to the pro-set rate of spray or the like. When the water is suddenly shut off by this kind of nozzle it tends to create a “water hamer”in the chamber so that users are expressly warned against use of such nozzles with the “Lawn Feeder”as supplied by Acme Burgess Inc. A new use is shown for a spherical feeder capsule with small feed holes which tends both to damp and limit the “water hammer”as an air bubble in the capsule is compressed, on resuming flow, the trapped air expands and positively ejects an amount of the concentrated solution from the feeder capsule into the flow. Thus in steady flow, a small and relatively constant rate of feeding is established, as shown in earlier-filed application; but an operator can by every pull of the trigger on the nozzle provide a “shot”of more concentrated solution.

Apparatus for adding chemicals in small amounts to water comprising: a. a supply of water at main pressure, b. an intermediate-velocity chamber, c. a water delivery device, d. a hose between said supply and said chamber, e. a conduit between said chamber and said device, f. a feeder in the form of a
Apparatus for adding chemicals in small amounts to water comprising: a. a supply of water at main pressure, b. an intermediate-velocity chamber, c. a water delivery device, d. a hose between said supply and said chamber, e. a conduit between said chamber and said device, f. a feeder in the form of a compact, stiff but flexible shell of waterproof plastic of substantially neutral bouyancy adapted to be contained within said chamber, and g. a dose of said chemical within said feeder, wherein: (i) said supply, hose, chamber, conduit, and device are interconnected to comprise a water-and-pressure-tight channel from said supply through said hose, chamber, conduit, and device, and (ii) said feeder is perforated by a number of small feed holes, selected to have a number, size, and distribution to provide a desired rate of feeding of said chemical, and is small enough and close enough to spherical in shape and to neutral bouyancy so that a normal flow rate through said chamber said feeder is free randomly to turn and move about, thereby to feed said chemical proportionately to said rate, wherein (iii) said device is a nozzle providing quick-acting control and cut-off of the flow of water through said channel, (iv) said feeder encloses trapped within it a bubble of gas, and (v) the amount of said entrapped gas, and the size of said feed holes is selected to control water hammering, and to provide a desired size shot of chemical to the target area of said nozzle with each cycle of said control, thereby providing a second mode of operation of the feeder.
