Abstract

A nozzle assembly including a rotary selector head provided with a plurality of integral nozzle tips which are selectively indexed into the fluid-flow line. The novel one-piece body design provides a shield to prevent water from being emitted toward the operator and the unit includes a simple O-ring seal which is spring loaded and pressure biased to prevent leakage.

Claims

1. In a nozzle assembly for attachment to a garden hose, the combination comprising, a main body portion including an inlet port for attachment of a garden hose fixture and an outlet port in communication with said inlet port, an annular collar means on said main body portion, a multiply perforated rotatable nozzle plate including means snugly embraced by said collar means and including a planar wall juxtaposed relative to a planar wall of said main body portion and overlying said outlet port, a recess in the main body portion surrounding said outlet port, a seal means in said recess and means in said recess urging said seal means into sealing engagement with the nozzle plate, centrally disposed means arranged to retain said nozzle plate within said collar and in firm contact with said seal means and indexing means permitting predetermined position of said perforations in said nozzle plate over said outlet port.

2. A nozzle assembly as claimed in claim 1, wherein the seal means is spring-urged into contact with the planar wall of the nozzle plate.

3. In a nozzle assembly as claimed in claim 2, wherein the seal means comprises a plurality of seal members.

4. In a nozzle assembly as claimed in claim 3, wherein means in said recess acts on a seal member to deform it radially in the recess.

5. In a nozzle assembly as claimed in claim 1, wherein there is a means to control fluid flow between the respective juxtaposed planar walls in addition to the seal means.

6. In a nozzle assembly as claimed in claim 2, wherein the recess is in communication with the ports so that fluid pressure supplements the spring pressure against the seal means.

7. In a nozzle assembly as claimed in claim 1, wherein the main body portion includes means permitting staking thereof onto the ground.

8. In a nozzle assembly as claimed in claim 1, wherein the main body portion is an integral cast element.

9. In a nozzle assembly as claimed in claim 5, wherein the means to control fluid flow is provided in the planar wall of said main body portion and is of an arcuate configuration.

10. In a nozzle assembly as claimed in claim 1, wherein at least one of the perforations provided in said multiply perforated planar wall includes valve means capable of emitting liquid in a circular pattern.

11. In a nozzle assembly as claimed in claim 10, wherein the valve means includes a perforated web-like base portion.

12. In A nozzle assembly for attachment to a garden hose, the combination comprising, a main body portion including means at one end thereof for attachment of a garden hose fixture, fluid flow seal means at the other end thereof, said body further including a perforated planar wall extending perpendicular to said seal means, an annular collar means on said main body portion, a perforated rotatable nozzle plate including means snugly embraced by said collar plate and including a planar wall juxtaposed relative to the planar wall of said main body portion, centrally disposed means arranged to retain said nozzle plate within said collar and in firm contact with said seal means and indexing means permitting predetermined positioning of perforations in said nozzle plate with a fluid-flow path, the planar wall of said main body portion including means to control fluid flow between the respective juxtaposed planar walls, said means to control fluid flow provided in the planar wall of said main body portion being of an arcuate configuration.

13. In a nozzle assembly for attachment to a garden hose, the combination comprising, a main body portion including an inlet port for attachment to a garden hose and an outlet port in communication with said inlet port, a multiply perforated rotatable nozzle plate including a planar wall juxtaposed relative to a planar wall of said main body portion and over-lying said outlet port, a seal means surrounding said outlet port in sealing engagement with said nozzle plate, centrally disposed means to retain said nozzle plate in firm contact with said seal means, indexing means permitting predetermined positioning of said perforations in said nozzle plate over said outlet port and means for providing a relief passage means for fluid leaking past said seal means and between said planar walls to prevent said fluid from squirting radially outwardly from between said walls.

14. In a nozzle assembly as claimed in claim 13, wherein said relief passage means comprises an arcuate recess provided in a planar wall.

15. In a nozzle assembly for attachment to a garden hose, the combination comprising, a main body portion including an inlet port for attachment to a garden hose and an outlet port in communication with said inlet port, a multiply perforated rotatable nozzle plate including a planar wall juxtaposed relative to a planar wall of said main body portion and over-lying said outlet port, a seal means surrounding said outlet port in sealing engagement with said nozzle plate, centrally disposed means to retain said nozzle plate in firm contact with said seal means, indexing means permitting predetermined positioning of said perforations in said nozzle plate over said outlet port, an annular collar means on said main body portion embracing said nozzle plate and circumferential means on said nozzle plate extending radially beyond the collar for grasping by the hand of the user to rotate said nozzle plate.

16. In a nozzle assembly for attachment to a garden hose, the combination comprising, a main body portion including an inlet port for attachment to a garden hose and an outlet port in communication with said inlet port, a multiply perforated rotatable nozzle plate including a planar wall juxtaposed relative to a planar wall of said main body portion and over-lying said outlet port, a seal means surrounding said outlet port in sealing engagement with said nozzle plate, centrally disposed means to retain said nozzle plate in firm contact with said seal means, indexing means permitting predetermined positioning of said perforations in said nozzle plate over said outlet port and means on said main body portion for receiving a part of a detachable stake to position said nozzle assembly on a lawn.
