Rainfall control for irrigation systems
First Claim
1. A control device for shutting off the motor which drives a pump for an irrigation system in response to a predetermined amount of rainfall thereby terminating the supply of water to at least one distribution outlet comprising a receptacle having upper and lower ends and side wall portions defining an enclosed chamber, an opening in said upper end of said receptacle, a float means disposed within said housing, mounting means for pivotally supporting said float means within said receptacle, said float means being pivotable from a first position to a second position as fluids are collected within said receptacle, securing means for selectively vertically adjusting the position of said mounting means with respect to said receptacle, first electrical switch means carried by said float means, electrical conductor means connecting said first electrical switch means to the motor, said first electrical switch means being operable when said float means is in said second position to shut down the motor to thereby prevent further operation of the pump in response to a predetermined accumulation of rain water within said receptacle.

- 14. A control device for shutting off the motor which drives a pump from an irrigation system in response to a predetermined amount of rainfall for supplying water to at least one distribution outlet comprising a receptacle having upper and lower ends and side wall portions defining an enclosed chamber, an opening in said upper end of said receptacle, a float means disposed within said housing, mounting means for pivotally supporting said float means within said receptacle, said float means being pivotable from a first position to a second position as fluids are collected within said receptacle, a plurality of vertically spaced openings through said side walls of said receptacle, at least one fastening element extendable through said openings in said side walls of said receptacle, said fastening elements being selectively engageable to said mounting means whereby said mounting means may be secured in various vertical positions relative to said receptacle, first electrical switch means carried by said float means, electrical conductor means connecting said first electrical switch means to the motor, said first electrical switch means being operable when said float means is in said second position to shut down the motor to thereby prevent further operation of the pump apparatus in response to a predetermined accumulation of rain water within said receptacle.
