Abstract
An apparatus is provided for distributing water to a lawn or garden. One or several units may be used to provide for custom watering at any point in the garden. With multiple units stacked, a custom watering pattern may be produced. Each unit has provisions for adjusting the angle of dispersion and the amount of water flow independently of each other.
Claims8
A lawn sprinkler nozzle assembly for attachment to a water supply bib comprising:
- a vertically oriented, cylindrical body having an exterior surface, an axial, central water conduit, a first means for rotational attachment of a lower end of the body to the water supply bib, a plurality of passages arranged circumferentially in the body, radially interconnecting the water conduit with the exterior surface, a plurality of separate angled body embossments arranged circumferentially on the exterior surface and extending radially away therefrom, an external threaded portion adjacent the passages, and a threaded attachment means adjacent to an upper end of the body;
- an open ended, vertically oriented, cylindrical valving sleeve having an internal threaded portion at a lower end thereof engaging the external threaded portion of the body, and a plurality of interior sleeve embossments extending radially inwardly each terminating with a concave surface, each of the embossments positioned opposite one of the water conduits of the body, the concave surfaces contacting the exterior surface of the body, the embossments of the valving sleeve being rotationally positionable so as to control a radially outward flow of water through the passages in the body, said flow entering a lower space formed between the body and the valving sleeve to move upwardly between the angled body embossments into a second space formed between the body and the valving sleeve, adjacent an upper open end of the valving sleeve;
- a water diverting washer rotationally threadably engaged with the threaded attachment means in a position immediately above the second space formed between the body and the valving sleeve, the diverting washer including a downfacing, upwardly angled annular surface for diverting the upward flow from the second space radially outwardly therefrom for disbursement thereof.
A water dispensing device comprising:
- a vertically oriented, cylindrical body providing an axial, central water conduit, the body having a lower end having a means for attachment of the lower end of the body to a water supply for conducting a water flow through the body, a means for disbursement of at least a portion of the water flow radially outward from the device, the body having an upper end having a threaded attachment means, for stacking a further water dispensing device, the further water dispensing device having an internally threaded connector for engagement therewith such that the water flow is conducted from the water dispensing device to the further water dispensing device in a vertically upward flow, and further comprising a cylindrical valving sleeve which is rotatable about the cylindrical body for adjusting water flow from the body.
