Abstract
A sprinkler and valve operator is disclosed that enables a single rotatable sprinkler head to be mounted coaxially to an upright irrigation pipe valve. The operator is comprised of two independently coaxially rotatable pipe sections that include a central valve operating mechanism. The lower pipe section includes mechanisms for releasably attaching the operator to a standard upright irrigation pipe valve. The valve operating mechanism engages and rotates the irrigation pipe valve actuator in response to rotational movement of the upper pipe section. A removable tripod may be provided to brace the pipe sections against operating forces produced through rotatable sprinkling head attached to the upper pipe section.
Claims11
A sprinkler and valve operator mountable directly to an irrigation pipe valve having an exterior valve actuator rotatable about a valve axis to open or close the valve, comprising:
- a first pipe section having an upper end and a lower end;
- mounting means at the lower end of the first pipe section adapted to releasably secure the first pipe section to the irrigation pipe valve coaxially with the valve axis;
- a second pipe section having an upper end and a lower end, said upper end of the second pipe section being adapted to rotatably mount a sprinkler head;
- bearing means coaxially joining the upper end of the first pipe section and the lower end of the second pipe section for rotation relative to one another;
- and
- valve operating means operably connected to the second pipe section and located within the first and second pipe sections for engaging the exterior valve actuator of an irrigation pipe valve and for opening or closing the irrigation pipe valve in response to manual rotation of the second pipe section relative to the first pipe section and irrigation pipe valve.
