Abstract

A nozzle spray assembly for insecticide made in two halves that are connected together and define an internal reservoir. The lower half has an arcuate shaped exterior surface and includes an inlet tube in communication with the reservoir. The lower half also has nozzle openings adjacent the arcuate surface so that when air is directed over the arcuate surface past the nozzle openings fluid is sucked into the inlet tube and reservoir and out the nozzle openings to spray insecticide onto the surrounding area.

Claims

1. A nozzle spray assembly for insecticide comprising:

an upper half;

a lower half defining an arcuate surface and including an inlet tube for receiving fluid to be dispensed, the inlet tube in communication with a reservoir defined by the upper and lower halves;

first connecting means for movably connecting the upper and lower halves; and

second connecting means for connecting the nozzle spray assembly to an outlet conduit of an air blower assembly, in which the second connecting means comprises a plurality of leg means to be disposed over the end of the outlet conduit and means for securing the legs to the outlet conduit;

wherein the upper and lower halves further conjointly define conjoint nozzle openings adjacent the arcuate surface such that, when air is directed over the arcuate surface past the nozzle openings, fluid is sucked into the inlet tube and reservoir and out said nozzle openings for spraying insecticide onto a surrounding area.

2. A nozzle spray assembly as set forth in claim 1 in which the inlet tube is connected to a container filled with liquid to be sprayed.

3. A nozzle spray assembly as set forth in claim 2 in which the container for the insecticide is supported on a backpack or belt of an operator.

4. A nozzle spray assembly as set forth in claim 1 in which the upper half includes upwardly extending wings for rotating the upper half relative to the lower half.

5. A nozzle spray assembly for insecticide comprising:

an upper half having an upper surface and a lower surface;

a lower half having an upper surface and an arcuate surface, and including an inlet tube for receiving fluid to be dispensed, the inlet tube in communication with a reservoir defined by the upper and lower halves;

nozzle openings adjacent the arcuate surface conjointly defined by channels in the upper surface of the lower half and varying sized channels in the lower surface of the upper half, whereby, when air is directed over the arcuate surface past the nozzle openings, fluid is sucked into the inlet tube and reservoir and out the nozzle openings for spraying the fluid onto a surrounding area; and

means movably connecting the upper and lower halves such that rotation of the upper half relative to the lower half varies the size of the nozzle openings to regulate the quantities of fluid being sprayed.

6. A nozzle spray assembly as set forth in claim 5 in which the channels in the lower half are equally spaced and generally semi-cylindrical and the channels in the upper half vary between the size of the channels in the lower half and a flat surface whereby the total size of the nozzle opening will be between double the size of the channels in the lower half and the size of the channels in the lower half.

7. A nozzle spray assembly as set forth in claim 6 provided with cooperating bumps and recesses in the upper and lower halves to positively locate the halves in position relative to each other.

8. A nozzle spray assembly as set forth in claim 7 in which the upper and lower halves are provided with cooperating indicia and flow indicator cut-outs.
