46759220, Jun 30, 1987

Filed:

Jan 4, 1985

Appl. No.:

6/688863

Inventors:

George M. Colin - Laguna Niguel CA
Edwin J. Hunter - Rancho Santa Fe CA

Assignee:

Odyssey Systems Limited - Laguna Niguel CA

International Classification:

E04H 319

US Classification:

4502

Abstract:

A compact swimming pool cover handling system including a pair of stationary roller support members, a roller for attaching the pool cover, and a hydraulic power attenuator for operation of the system. The hydraulic power attenuator includes controls for reversing directions of the roller without removing the source of liquid operating the device.

Appl. No.:

5/418309

Inventors:

Edwin J. Hunter - Riverside CA

Assignee:

The Toro Company - San Marcos CA

International Classification:

F01B 900
F01B 3100
F01B 2506

US Classification:

92140

Abstract:

An automatic irrigation controller apparatus having a cam follower operated bank of pilot valves for operating selected pilot operated water valves throughout a watering or irrigation system is provided with a water powered means for receiving water under pressure from a source thereof and a member driven in a predetermined manner by the force of such water for driving a cam means to operate said cam followers via power transmission means between the water driven member and a cam shaft mounting said cam. A water piston is mounted in a cylinder with associated water valve means for selectively connecting the cylinder to a source of water under pressure and to a vent to provide a reciprocal movement for the piston, a return stroke for the piston being accomplished through the provision of a spring. A reciprocal piston movement is translated through a power transmission means including a drive ratchet wheel connected to the piston and a driven ratchet wheel connected to the cam shaft. An escapement mechanism is provided with a ring gear mounted about an engagement with a plurality of planetary gears mounted by a carrier about a sun gear driven by an input shaft of the apparatus connected to the cam shaft.
