Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
252 words
For use in conjunction with water motor powered field irrigation equipment, a control system, sAid system comprising a main water pipe, a pair of hoses extending from said pipe, a valve connecting each hose to the pipe and controlling the flow of water from the pipe to the hose, means for selectively simultaneously opening either valve and closing the other valve, said hoses being adapted for operative engagement with a water motor so as to, in response to the selective opening and closing of the valves, effect a selective driving of the water motor in either of two directions, said means for selectively opening and closing the valves including a valve lever fixed to each valve and movable in one direction to effect an opening of the corresponding valve, each valve lever being movable in a second direction to effect a closing of the associated valve, a reversing member movably mounted on the pipe, said reversing member, in a first position thereof, having a first valve cable connected thereto and extending therefrom to a first valve lever in a moved position opening the associated valve, and a second valve cable connected to the reversing member and extending therefrom to the second valve lever in a moved position closing the corresponding valve, said reversing member being movable between said first position and a second position wherein the first valve cable effects a valve closing movement of the corresponding lever and the second valve cable effects a valve opening movement of the corresponding lever.
Claim 2
Dependent Claim
252 words
For use in conjunction with water motor powered field irrigation equipment, a control system, sAid system comprising a main water pipe, a pair of hoses extending from said pipe, a valve connecting each hose to the pipe and controlling the flow of water from the pipe to the hose, means for selectively simultaneously opening either valve and closing the other valve, said hoses being adapted for operative engagement with a water motor so as to, in response to the selective opening and closing of the valves, effect a selective driving of the water motor in either of two directions, said means for selectively opening and closing the valves including a valve lever fixed to each valve and movable in one direction to effect an opening of the corresponding valve, each valve lever being movable in a second direction to effect a closing of the associated valve, a reversing member movably mounted on the pipe, said reversing member, in a first position thereof, having a first valve cable connected thereto and extending therefrom to a first valve lever in a moved position opening the associated valve, and a second valve cable connected to the reversing member and extending therefrom to the second valve lever in a moved position closing the corresponding valve, said reversing member being movable between said first position and a second position wherein the first valve cable effects a valve closing movement of the corresponding lever and the second valve cable effects a valve opening movement of the corresponding lever.
Claim 3
Dependent Claim
38 words
The system of claim 1 wherein said reversing member comprises an elongated rotatably mounted bar having oppositely projecting cable securing arms fixed at spaced points thereon, each of said valve cables being secured to one of said arms.
Claim 4
Dependent Claim
32 words
The system of claim 2 wherein said reversing bar includes a manipulating handle fixed thereto and projecting radially therefrom for a rotation of the bar and an alternating operation of the valves.
Claim 5
Dependent Claim
21 words
The system of claim 3 including reversible winch and cable means engaged with said manipulating handle for a controlled swinging thereof.
Claim 6
Dependent Claim
26 words
The system of claim 4 wherein said cable means parallels the main water pipe and operatively controls multiple reversing bars at spaced points along said pipe.
Claim 7
Dependent Claim
120 words
The system of claim 5 wherein each valve comprises an inlet, an outlet, a flow passage therebetween, a valve seat within said flow passage, a valve member selectively engageable within said valve seat for a closing of the flow passage, an elongated valve stem having one end affixed to said valve member, a flexible diaphragm fixed to the remote end of said valve stem and being exposed to the internal water pressure within said valve unit with internal water pressure effecting a constant biasing of the diaphragm outwardly into a valve member seating position, the associated valve lever engaging said diaphragm and effecting a selective inward movement of the diaphragm against the water pressure and an opening of the valve.
