Claim 4

An automatic watering device comprising a fluid pressure valve having a hollow body provided with an outlet, an inlet having a shelf provided with a valve bore and a valve seat, a boss having a cavity and a first conduit having a selected diametrical area, a second conduit having a selected diametrical area greater than said first diametrical area, and a duct between said cavity and said outlet, an inlet valve comprising a valve body having a valve head having a preselected area, a valve stem having an arcuate fluid pressure surface provided with a preselected area smaller than said first mentioned preselected area, said valve stem slidably mounted in said valve bore, a fluid sealing membrane fastened to said valve head and to said hollow body to fluid seal one end of said inlet and to accommodate reciprocal movement of said inlet valve, a cap having a chamber, means fastening said cap to said hollow body with said chamber aligned with said valve head, a diaphragm provided with a plunger valve port, a first port and second port, means fastening said diaphragm in said cavity with said plunger valve port between said cavity and said duct, said first conduit connecting said inlet with said cavity through said first port, said second conduit connecting said chamber with said cavity through said second port, a hollow cap having a flanged end abutting the edge of said diaphragm, means fastening said flanged end within said cavity, a solenoid surrounding and fastened to said hollow cap, a plunger having a valve end slidably mounted within said hollow cap, resilient means within said hollow cap abutting said plunger to urge said valve end into said plunger valve port whereby energization of said solenoid moves said valve end away from said valve port, against the resilient means to permit fluid to flow from said chamber to and through said duct, and inlet fluid to flow through said first conduit to and through said duct, whereby said inlet valve moves away from said valve seat to permit fluid to flow through said valve bore to said outlet, a moisture sensitive hydroelectrical switch comprising a hollow body having an inlet end, an outlet end, and a dry chamber, an electrical switch, having electrical conduits provided with switch contacts, fastened in said dry chamber, a fluid tight pressure gland, having a medial passageway, rotatively connected to said hollow body at said outlet end with said electrical conduits passing through said medial passageway, a body extension having a hollow core fastened to the inlet end of said hollow body, an adjustable sleeve, provided with an axial passageway, rotatively connected to said body extension, a rod having a head, fabricated from waterproof electrical insulation, slidably mounted in said axial passageway, a peg, fabricated from electrical insulated material, fastened in said head, a hollow sleeve, fabricated from resilient material, interposed between said adjustable sleeve and said head to urge said peg against said switch contacts, a plurality of collars, fabricated from moisture sensitive material, which expands when wet and contracts when drying, fastened to said rod to move said peg toward and away from said switch contacts to open and close said electrical switch, and means connecting said electrical conduits to said solenoid.

Claim 5

An automatic watering device as defined in claim 2, an electrical circuit having a transformer to a source of power, one of said electrical conduits in said electrical circuit connecting said transformer to a contact on said electrical switch, a second of said electrical conduits having said solenoid and a relay connected to another of said switch contacts and to said transformer, whereby said peg, actuated by said moisture operated switch, shifts said switch contacts and therefore said switch from closed to open position to energize said relay and thereby said solenoid whereby said armature plunger is actuated to open valve position to allow water to flow from inlet 11 to outlet 12.

Claim 6

An automatic watering device as defined in claim 3, said electrical circuit having a plurality of moisture operated switches, and a plurality of fluid pressure valves, one for each moisture operated switch, a plurality of solenoids, one for each fluid pressure valve, a timing motor having a timing disc with a dwell, a plurality of manually operated start buttons, a plurality of manually operated stop buttons, each start and stop button being an electrical switch in said electrical circuit to open or close said electrical circuit, a second relay and a third relay, a second electrical switch, a third electrical switch, a fourth electrical switch, a fifth electrical switch a cam arm having a follower connected to said fourth and fifth electrical switches, said follower engaging said timing disc and dwell, actuation of one of said plurality of start buttons closes the electrical circuit to a moisture operated switch, if said last mentioned switch is in wet position, it will be in open position and the solenoid will not operate to lift said armature plunger out of the plunger valve port, if said last mentioned switch is in dry position, said start button will close the electrical circuit to said first relay and to said second and third switches and to said motor to rotate said motor and timing disc to close said fourth and fifth switches to energize first solenoid and thereby lift said armature plunger out of the plunger valve port to open the valve for water to flow to said moisture operated switch, whereby said switch is actuated to open position and thereby open the electrical circuit.
