US3753315A — Device for irrigation especially of flower pots

Claim 1

Independent Claim 90 words

A device which is arranged as a container adaptable to a flower stand, said container including a suction feeding water tank having an airtight filling stopper and two water outlets, one of said outlets being situated in a cavity hermetically separated from soil in said stand, said cavity being open to the atmosphere, the other outlet being in another cavity separated from said soil by a porous walling, at least one separate air inlet existing in one of said cavities at a level below the water outlet in said cavity.

Claim 2

Independent Claim 90 words

A device which is arranged as a container adaptable to a flower stand, said container including a suction feeding water tank having an airtight filling stopper and two water outlets, one of said outlets being situated in a cavity hermetically separated from soil in said stand, said cavity being open to the atmosphere, the other outlet being in another cavity separated from said soil by a porous walling, at least one separate air inlet existing in one of said cavities at a level below the water outlet in said cavity.

Claim 3

Dependent Claim 161 words

An irrigation device comprising a closed, hollow receptacle for water defining a recess adapted for receiving a flower pot, said receptacle having a hermetically closable filling stopper at the upper end thereof and a water outlet at the lower end for supply of water to the flower pot, an air conduit having an inlet which opens into the top of the receptacle above the water level therein and an outlet which opens into said recess, means in said space defining two cavities therein, a first cavity being in communication with said water outlet for freely receiving water therefrom, the second cavity being open to the atmosphere and in communication with said outlet of the air conduit, means providing communication between said cavities to permit water flow into said first cavity when the level of water in said second cavity falls below the outlet of the air conduit, and absorption means in one of said cavities for supplying water to said pot.

Claim 4

Dependent Claim 161 words

An irrigation device comprising a closed, hollow receptacle for water defining a recess adapted for receiving a flower pot, said receptacle having a hermetically closable filling stopper at the upper end thereof and a water outlet at the lower end for supply of water to the flower pot, an air conduit having an inlet which opens into the top of the receptacle above the water level therein and an outlet which opens into said recess, means in said space defining two cavities therein, a first cavity being in communication with said water outlet for freely receiving water therefrom, the second cavity being open to the atmosphere and in communication with said outlet of the air conduit, means providing communication between said cavities to permit water flow into said first cavity when the level of water in said second cavity falls below the outlet of the air conduit, and absorption means in one of said cavities for supplying water to said pot.

Claim 5

Dependent Claim 33 words

A device as claimed in claim 2 wherein said cavities are the same size, said absorption means being of the same size at said cavities and selectively placeable in one or the other.

Claim 6

Dependent Claim 66 words

A device as claimed in claim 2 wherein said hollow receptacle includes an inner wall defining said recess, said wall being provided with a groove with a hermetic plate covering the same and forming said air conduit, said plate having a lower edge which is located above the lower end of said groove and which defines the upper edge of said outlet of said air conduit.

Claim 7

Dependent Claim 28 words

A device as claimed in claim 4 wherein said lower edge of said plate is horizontal and linear, said plate being adjustable along the length of the groove.

Claim 8

Dependent Claim 195 words

An irrigation device comprising a closed water tank having a hermetically closable filling stopper at the upper end thereof and a water outlet at the lower end thereof, a receptacle for receiving a flower pot, said receptacle defining two cavities therein, means connecting a first of said cavities with said water outlet from the tank to allow free flow of water from the tank to the first cavity, the second of the cavities being open to the atmosphere, an air conduit having an outlet connected to the second cavity and an inlet connected to the tank at the upper end thereof above the water level in the tank, means providing communication between said cavities to permit overflow from the first cavity to the second to establish a height of water in said cavities to the level of the water inlet, said outlet of the air conduit being below the water outlet to enable flow of water from said water outlet into said first cavity only when the level of water has dropped below the outlet of said air conduit, and absorption means disposed in one of said cavities for supplying water to the flower pot.

Claim 9

Dependent Claim 195 words

An irrigation device comprising a closed water tank having a hermetically closable filling stopper at the upper end thereof and a water outlet at the lower end thereof, a receptacle for receiving a flower pot, said receptacle defining two cavities therein, means connecting a first of said cavities with said water outlet from the tank to allow free flow of water from the tank to the first cavity, the second of the cavities being open to the atmosphere, an air conduit having an outlet connected to the second cavity and an inlet connected to the tank at the upper end thereof above the water level in the tank, means providing communication between said cavities to permit overflow from the first cavity to the second to establish a height of water in said cavities to the level of the water inlet, said outlet of the air conduit being below the water outlet to enable flow of water from said water outlet into said first cavity only when the level of water has dropped below the outlet of said air conduit, and absorption means disposed in one of said cavities for supplying water to the flower pot.

Claim 10

Dependent Claim 33 words

A device as claimed in claim 6 wherein said cavities are the same size, said absorption means being of the same size at said cavities and selectively placeable in one or the other.

Claim 11

Dependent Claim 60 words

A device as claimed in claim 6 wherein said tank includes an inner wall having a groove, and a hermetic plate covering the groove and together therewith forming said air conduit, said plate having a lower edge which is located above the lower end of said groove and which defines the upper edge of said outlet of said air conduit.

Claim 12

Dependent Claim 28 words

A device as claimed in claim 8 wherein said lower edge of said plate is horizontal and linear, said plate being adjustable along the length of the groove.

Claim 13

Dependent Claim 27 words

A device as claimed in claim 6 wherein said tank is constituted as an annular member to surround the flower pot and serve as a cover therefor.
