Abstract: A cable driven irrigation device has a frame that acts as a manifold to supply a sprinkler head and a separate spray nozzle. The frame is supplied with an externally triggered latching valve. The valve is held in the open position by a spring and has an internal flap that enters the flow of water through the valve when the external trigger is moved. The water flow moves the flap to the closed position and holds it there until the water pressure is removed. The spray nozzle dispenses water onto an exposed turbine which drives a gearbox. The gearbox is coupled to a spool which can wind up a cord. The spool being wound is what pulls the sprinkler along. A knot near the end of the cord engages the external trigger to stop the flow of water into the frame.

Abstract: A traveling sprinkler system comprising: a sphere shaped surface; at least one wheel over a circumference of the sphere shaped surface, where the at least one wheel divides the sphere into a first half and a second half; a plurality of holes on both the first half and the second half of the sphere shaped surface; a water hose receptacle, where the water hose receptacle receives a flow of water from a water hose; and wheel gears within the sphere, where the flow of water transfers over the wheel gears to enable the movement of the at least one wheel and the flow of water transfers through the plurality of holes creating a sprinkling action.

Abstract: A hose-fed lateral move irrigation system and method that utilizes a pipe with a plurality of sprinklers attached to a wheeled cart that pulls a flexible-hose assembly therebehind using at least one onboard winch and travels laterally with the pipe and sprinklers relative to a field so that a sufficient amount of hose may be used to enable total automation of the system.

Abstract: A chemical dispenser which is selectively removably mounted on a travelling lawn sprinkler. The chemical dispenser dispenses liquid chemical into the water being sprinkled onto the lawn by the water distributor as the self-propelled travelling lawn sprinkler propels itself across a lawn.

Abstract: Aspects of the invention relate to a sprinkler apparatus providing multiple operational modes. For instance, the apparatus can operate as a conventional traveling sprinkler. In addition, the apparatus can provide one or more additional ports so that a user can attach additional hoses or other watering or irrigation equipment. The apparatus can include a switch so that a user can selectively switch a valve so that a fluid flows substantially exclusively to one of these additional ports. In one embodiment, a hose or other fluid dispensing device can be attached to one of the additional ports so that an operator can wash a car, water hanging pots, or perform other watering functions that cannot be accomplished by a traveling sprinkler.

Abstract: A lawn irrigation system including a frame, a motor, a sprinkler arm, at least one drive wheel, and a cover. The motor is operably attached to the frame. The at least one drive wheel is operably connected to the motor. The sprinkler arm is operably connected to the motor for dispersing water in a selected pattern. The cover is attached to the frame so that the cover at least partially covers the frame, the motor, and the at least one drive wheel so that the lawn irrigation system resembles an object other than a sprinkler.

Abstract: An irrigator has a single irrigation arm adapted to move in reciprocal rotational motion. In a first setting, the irrigator sprays irrigating liquid at a first orientation with respect to the arm to move the arm in a first direction. In a second setting, the irrigator sprays irrigating liquid at a second orientation with respect to the arm to effect a reversal in the rotational direction of the arm. Alternating mechanisms are provided to alter the arm between the first and second settings.

Abstract: A mobile robot is provided with a fluid conduit which is connected to an on board fluid-responsive turbine. An on board electric generator and/or hydraulic pump is connected to the mechanical output of the turbine such that power for the robot is generated when the turbine rotates due to the flow of fluid through the conduit. The fluid may then be expelled through a nozzle and used as an extinguishant, a propellant or a coolant.

Abstract: A wheeled vehicle carries a reel 3 on to which part of a long length of hose may be coiled, with the end of the hose coupled to a hose connection 10 which conveys water to a hollow axle 7 about which the reel 3 rotates and through a swivel coupling 12 to a hollow shaft 13 from which the water flows through shorter hoses 16, mounted on long arms 14, to nozzles 17. Passage of the water from the nozzles causes the arms 14 to rotate about a vertical or nearly vertical axis and this rotation is transmitted to the reel 3 which rotates. Rotation of the reel 3, which is preferably disposed with its axis vertical, causes more of the hose to become coiled on the reel and this in turn causes the vehicle to move along the ground.

Abstract: A jet nozzle for use in propelling a trolley or sledge provided with a television or video camera along a conduit, such as a sewer, for use in inspecting the interior of the conduit, the jet nozzle comprising a casing having an end wall provided with a plurality of discharge openings communicating with a chamber formed between said end wall and a transverse wall, an inlet in communication with the chamber and connected to a home, a bearing provided on the casing mounting a connector member for connecting the jet nozzle to the trolley or sledge and allowing the casing to rotate relative to the connector member.

Abstract: A mobile agricultural water cannon to transfer water from sloughs and shallow ponds to adjoining land has (1) a suction pod to collect the water into a suction chamber, (2) a tail boom assembly to lower the suction pod into the water from adjoining land, (3) a suction boom to move the water through the tail boom assembly from the suction pod to a high pressure pump on the suction boom, and (4) a pressure boom to discharge the water from the high pressure pump; there is a priming pump on the suction pod to prime the high pressure pump. The suction and pressure booms are mounted on wheels, the other parts being attached to these to pivot between operating and transport positions for operation and towing by a motive power source which can power the high pressure pump and the priming pump, and pivot the tail boom assembly.

Abstract: A hydraulic circuit and a wheeled self-propelled moveable frame provides a one-way feed of water under pressure selectively bearing a liquid soap or a liquid rinse chemical via a wind up hose mounted on a spool via a drive motor to axle to belt to clutch to shaft on the moveable frame through a multi-way directional valve to a water powered drive motor for driving the moveable frame forward and reverse relative to an open end of a vehicle body and said spool. A water cylinder changes the angle of inclination of a floor nozzle tube rotatable about its axis horizontally at the front of the moveable frame and bears a series of longitudinally spaced nozzles, when the machine travel reverses towards the open end of the vehicle body. The multi-way directional valve changes the water flow direction upon impact of a sensor operatively coupled thereto and projecting forwardly of the front of the wheeled self-propelled moveable frame.

Abstract: A head is disclosed for use in cleaning pipes using a technique in which the head projects water backwardly so as to be driven along the pipe pulling a water supply hose with the head following which the supply hose is pulled from the pipe to withdraw the head thus forcing collected debris from the pipe. The head comprises a cylindrical body having a nose and a rear wall in which the jets are positioned. The body is wrapped around by longitudinal skid bars spaced angularly of the cylindrical body and welded to the nose and welded to a coaxial pipe supplying water to the cylindrical body. The jets are inclined outwardly at a shallow angle of the order of 1.degree. to 6.degree..
