A spline for joining irrigation tubing includes an elongated body portion. The body is configured to be inserted into and substantially fill a channel formed by aligning an interior channel in a female tubing end and a corresponding exterior channel in a male end. One or more serrations or slots in the body facilitate bending the body into annular channels. The end of the body is tapered to facilitate its insertion, including a taper along its length (such as on the side opposite the serrations), and a gripping portion on the spline further facilitates insertion and removal. Related methods are disclosed.

A sprinkler head apparatus includes two separately molded members secured together independently of a water volume control member. A number of selectively removable devices that withstand the forces of water in irrigation systems and can be easily removed by the user without additional hardware are situated at the entry point of water outflow channels to provide the user directional control of the water sprayed from the apparatus. Registration elements are provided to ensure the proper alignment between the members of the apparatus. Correspondingly, indicia located at upper and lower external surfaces of the assembled apparatus reduce or eliminate the need to disassemble the apparatus or intermittently test the water spray pattern to ensure proper installation of the apparatus. Preferred methods for assembling the apparatus, for directing the outflow of water, and for aligning the members of the apparatus are disclosed.

An improved apparatus and method are provided for irrigation systems such as automated sprinkler systems. A pre-assembled housing or valve box includes an inlet for receiving water and one or more outlets for distribution of water to other components in the irrigation system, and also includes manifolding and power and valve means for selectively controlling the flow of water from the outlets. Many of the manifold components are integrally molded with each other and provided in modular form so that the system can be relatively compact and can be customized into a variety of configurations. The manifold can consist of or include integrally formed or interconnected valve bases. The electrical power system includes a main terminal box with power lines leading to connectors adjacent each outlet, so that solenoid valves may be readily connected thereto and replaced as necessary. O-rings, non-conducting gel, and similar mechanisms are provided to ensure the water-tightness of the electrical connections. The box and its components may be manufactured, assembled, and installed more reliably, conveniently and economically than conventional irrigation systems, and may also be tested before installation.

Apparatus and methods permit splicing or joining a plurality of tubing ends. A central tubular member has a fluid passage therethrough. The tubing ends are mounted over the extremities of the tubular member, and are held in place by a multi-part sleeve around the central member and cooperating detents (on the exterior of the tubular member and on the interior of the sleeve) that pinch or bite the tubing when the sleeve is actuated (such as via a turnbuckle action) to force cooperating pairs of the detents toward each other.

Apparatus and methods include an adaptor to establish a flow path through the side of a first piece of tubing (rather than the end of the tubing) into a second piece of tubing or other device. The adaptor includes a threaded head slightly larger than the hole in the side of the tubing into which it is to be inserted, and gripping portions to assist in forcing the threaded head through the opening. After the head has been inserted, a sealing element is tightened to prevent leakage. To join lay-flat tubing to drip tubing, the other end of the adaptor includes an annular barbed end; a sleeve member around the barbed end; and cooperating structures acting between the barbed end and the sleeve to move those relative to each other. Barb structures on the sleeve member cooperate with the barbed end to sealingly engage the drip-tubing end.

The present invention is directed to a sprinkler apparatus and related methods for the distribution of fluid. The invention preferably includes a nozzle rotatably driven by a pressurized flow of fluid along a fluid path. The invention preferably includes a housing separating a magnetic drag coupling assembly from the fluid path. The coupling assembly preferably includes spaced apart magnets configured to exert an attractive force on each other to rotate one magnet in response to the rotation of the other magnet, and a resistive/drag force to oppose the continuous rotation of the nozzle. Pressure offsetting structures minimize or even neutralize the upward/downward forces that the flowing fluid otherwise would exert on the rotating shaft assembly.
