Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
In combination with a system for selectively irrigating remote zones each having electromagnetically operated valves for controlling the irrigation, a control box having mounted thereon a rotary zone selector switch having a center terminal and a series of spaced terminals, and a double pole single throw switch, said control box having mounted thereon a transformer having primary and secondary windings, and terminal connection means having first and second power input terminals, a common terminal, a series of terminals for connection to said electromagnetically operated valves, and an accessory terminal, an electrical connection from said first input terminal to said primary transformer winding, an electrical connection from said second input terminal through said double pole single throw switch to said transformer primary winding, an electrical connection from said transformer secondary winding to the center terminal of said zone selector switch, an electrical connection from said transformer secondary winding to the common terminal of the terminal connection means, electrical connections from each of said series of said spaced zone selector switch terminals to said series of terminals for said valves, respectively, and an electrical connection from one said secondary transformer connection through said double pole single throw switch to said accessory terminal.
Claim 2
Dependent Claim
200 words
In combination with a system for selectively irrigating remote zones each having electromagnetically operated valves for controlling the irrigation, a control box having mounted thereon a rotary zone selector switch having a center terminal and a series of spaced terminals, and a double pole single throw switch, said control box having mounted thereon a transformer having primary and secondary windings, and terminal connection means having first and second power input terminals, a common terminal, a series of terminals for connection to said electromagnetically operated valves, and an accessory terminal, an electrical connection from said first input terminal to said primary transformer winding, an electrical connection from said second input terminal through said double pole single throw switch to said transformer primary winding, an electrical connection from said transformer secondary winding to the center terminal of said zone selector switch, an electrical connection from said transformer secondary winding to the common terminal of the terminal connection means, electrical connections from each of said series of said spaced zone selector switch terminals to said series of terminals for said valves, respectively, and an electrical connection from one said secondary transformer connection through said double pole single throw switch to said accessory terminal.
Claim 3
Dependent Claim
40 words
The combination of claim 1, wherein an overload circuit breaker having a reset button is mounted on said control box and is electrically inserted in the connection between the transformer secondary winding and the center terminal of the selector switch.
Claim 4
Dependent Claim
33 words
The combination of claim 2, wherein a power indicator light is mounted on the control box and is electrically connected to the common terminal and to the center terminal of the selector switch.
Claim 5
Dependent Claim
36 words
The combination of claim 3, wherein a fuse retainer for a removable fuse is mounted on the control box and is electrically inserted in the connection from the first input terminal to the primary transformer winding.
