Abstract
Abstract A maintenance control apparatus for a lawn watering system includes an accessible electrical receptacle and a portable switching unit. The unit includes a plug for detachably coupling into the receptacle and a selection switch for selectively supplying power through the receptacle to the solenoid water valves. The valves are thereby selectively openable remotely and independently of the clock controller of the watering system. An auxiliary battery and jack are provided to substitute for the main power. A portable master switch electively supplies power to open or close the master valve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
227 words
A maintenance control apparatus for a lawn watering system including a multiplicity of sprinklers for dispersing water onto a lawn, a plurality of water conduits receptive of pressurized water with each conduit communicating with at least one of the sprinklers, a plurality of electrically actuated dedicated valves each being disposed in one of the conduits, a plurality of electrical power points each being connected electrically to one of the dedicated valves, and internal control means communicating with an electrical power source for selectively supplying electrical power to the power points and thereby to the dedicated valves so as to selectively provide water to the sprinklers, the power points and the internal control means being disposed in an internal location so as to be generally inaccessible, wherein the apparatus comprises: an accessibly mounted receptacle having a plurality of first connectors each being connected electrically to one of the power points, and a portable switching system comprising coupling means for detachably coupling into the receptacle and having a plurality of second connectors adapted to electrically contact corresponding first connectors, and selective switching means communicating with a power means for selectively supplying electrical power to the second connectors and thereby to the dedicated valves, whereby, with the coupling means coupled into the receptacle, the dedicated valves are selectively openable remotely by the switching means independently of the internal control means.
Claim 2
Dependent Claim
227 words
A maintenance control apparatus for a lawn watering system including a multiplicity of sprinklers for dispersing water onto a lawn, a plurality of water conduits receptive of pressurized water with each conduit communicating with at least one of the sprinklers, a plurality of electrically actuated dedicated valves each being disposed in one of the conduits, a plurality of electrical power points each being connected electrically to one of the dedicated valves, and internal control means communicating with an electrical power source for selectively supplying electrical power to the power points and thereby to the dedicated valves so as to selectively provide water to the sprinklers, the power points and the internal control means being disposed in an internal location so as to be generally inaccessible, wherein the apparatus comprises: an accessibly mounted receptacle having a plurality of first connectors each being connected electrically to one of the power points, and a portable switching system comprising coupling means for detachably coupling into the receptacle and having a plurality of second connectors adapted to electrically contact corresponding first connectors, and selective switching means communicating with a power means for selectively supplying electrical power to the second connectors and thereby to the dedicated valves, whereby, with the coupling means coupled into the receptacle, the dedicated valves are selectively openable remotely by the switching means independently of the internal control means.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 wherein the receptacle has a further first connector being connected electrically to the power source, and the power means comprises the coupling means having a further second connector adapted to electrically contact the further first connector, and the switching means having a common terminal connected electrically to the further second connector.
Claim 4
Dependent Claim
43 words
The apparatus of claim 2 wherein the power means further comprises auxiliary means for detachably coupling into the power source so as to disconnect the power source from the switching means and substitute therefor auxiliary power in electrical contact with the switching means.
Claim 5
Dependent Claim
79 words
The apparatus of claim 3 wherein the auxiliary means comprises a normally closed jack switch disposed to normally provide a power connection between the further first connector and the power source, and a portable battery pack comprising a battery and a jack plug connected thereto, the jack switch and the jack plug being coactable so that with the jack plug plugged into the jack switch the power connection is opened and a substitute connection of the battery is effected.
Claim 6
Dependent Claim
96 words
The apparatus of claim 1 wherein the watering system further includes deactivation means for deactivating the power source from the watering system, and the apparatus further comprises signaling means for signaling whether the power source is deactivated, the signaling means comprising the receptacle having a supplementary first connector for being connected as a return line to the power source, the coupling means having a supplementary second connector for electrically contacting the supplementary first connector, and a light bulb disposed in the switching system and connected electrically between the supplementary first connector and the supplementary second connector.
Claim 7
Dependent Claim
92 words
The apparatus of claim 5 wherein the watering system further includes rain sensing means electrically connected to the dedicated valves so as to deactivate the dedicated valves from opening in an event of rain, and the apparatus further comprises override means for overriding the rain sensing means, the override means comprising the receptacle having a pair of extra first connectors and the plug having a pair of extra second connectors each for electrically contacting a corresponding extra first connector, and the pair of extra connectors being connected across the rain sensing means.
Claim 8
Dependent Claim
122 words
The apparatus of claim 1 wherein: the watering system further includes manifold means for distributing water into the conduits, and an electrically actuated master flow means for electively supplying the pressurized water to the manifold means, the apparatus further comprises the receptacle having an additional first connector for being connected electrically to the master flow means, and the coupling means having an additional second connector adapted to electrically contact the additional first connector, and the switching system further comprises a portable master switch communicating with the power means for electively supplying electrical power to the additional second connector and thereby to the master flow means, whereby upon the coupling means being coupled into the receptacle the master flow means is actuatable remotely.
Claim 9
Dependent Claim
43 words
The apparatus of claim 7 further comprising a fixed master switch for mounting accessibly and connecting between the power source and the additional first connector so as to electively hold the master flow means off except when overridden by the portable master switch.
Claim 10
Dependent Claim
62 words
The apparatus of claim 8 wherein the watering system further includes a communal power point receptive of power from the internal control means whenever the internal control means also supplies power to any of the dedicated valves, and the fixed master switch has an input terminal connected to the communal power point and an output terminal connected to the master flow means.
