Abstract
Abstract ABSTRACT OF THE DISCLOSURE This invention relates to a device for automatically watering plants or flowers. The device comprises a pot adapted to retain the plant or flower therein. The pot has at least one orifice at the bottom thereof. A tank is provided which holds water and the tank and the pot sits on a base. An automatic level control means is provided which controls the flow of water to the base from the tank based on the consumption of water from the base by the plant or flower and the loss of the water to environmental conditions. This device allows for accurate control of the supply of water to plants or flowers, especially over an extended period of time.

A device as claimed in claim 1 wherein said automatic level control device comprises a double nozzle provided with a narrow, calibrated orifice through which
Claim 8
Dependent Claim
31 words
Claim 7 continue... the water flows from the tank to the base, and a larger orifice obturated at the upper side by a ball having a specific gravity greater than water.
Claim 9
Dependent Claim
15 words
A device as claimed in claim 7 wherein said larger orifice is cylindrical in shape.
Claim 10
Dependent Claim
59 words
A device as claimed in claim 8 wherein said larger orifice is split into a first part and a second part, said first part being smaller than said second part and said first part being obturated at the under side by said ball, said second part being larger than said first part and creating an enclosure for said ball.
Claim 11
Dependent Claim
20 words
A device as claimed in claim 9 wherein said first and said second parts are joined by a truncated cone.
Claim 12
Dependent Claim
31 words
A device as claimed in claim 7 wherein said narrow orifice extends to the upper side of said nozzle and said larger orifice extends to the lower side of said nozzle.
Claim 13
Dependent Claim
68 words
A device as claimed in claim 7 further including a limiting means adapted to limit to the movement of said ball. 13. A device as claimed in claim 1 wherein said automatic level control means comprises a double nozzle wherein it is inserted in a vertical, interior wall of the tank, said nozzle being provided with two, L-shaped orifices, one of said orifices being a narrow, calibrated orifice
Claim 14
Dependent Claim
34 words
Claim 13 continue . . . through which water flows from the tank to the base, and the other orifice being a larger orifice through which air enters the tank to replace the water.
Claim 15
Dependent Claim
31 words
A device as claimed in claim 13 wherein said narrow orifice extends to the inner side of the nozzle and the larger orifice extends to the center side of the nozzle.
Claim 16
Dependent Claim
21 words
A device as claimed in claim 13 wherein said larger orifice is obturated at the inner side by a check valve.
Claim 17
Dependent Claim
76 words
A device as claimed in claim 1, in which the automatic level control means is composed of a single nozzle of a larger diameter through which the water flows out of the tank into the base and the air enters the tank to replace the water, a plug guided by the interior surface of the nozzle, and a spring placed between the plug and the base, which pushes up the plug tending to obturate the nozzle,
Claim 18
Dependent Claim
33 words
A device as claimed in claim 16, in which the nozzle is located on the same vertical axis as the orifice on the top of the tank through which the tank is filled.
Claim 19
Dependent Claim
53 words
A device as defined in claim 16, in which the plug which closes the orifice at the top of the tank is provided with a rod which pushes down the plug at the bottom of the tank, keeping the nozzle open as long as the plug at the top is tightly closed. .
Claim 20
Dependent Claim
58 words
A device as claimed in claim 1, in which the automatic level control means is composed of a single nozzle of a larger diameter tightly inserted in the bottom horizontal wall of the tank, a plug which obturates the nozzle when pushed from down and a floater which actuates the plug by means of a demultiplicating articulated lever.
Claim 21
Dependent Claim
88 words
A device as claimed in claim 19, in which the floater is actuated by the water level in the base such that when the level of the water in the base is decreasing, the floater actuates the plug to open the nozzle, letting the water from the tank flow out in the base and the air to enter the tank until the water in the base reaches a certain level when the floater pushes up the plug to close the nozzle thus keeping the water in the tank.
Claim 22
Dependent Claim
75 words
A device as claimed in claim 1, in which the automatic level control means is composed of a single nozzle of a larger diameter through which the water flows out of the tank, and the air enters the tank to replace the water, until the water in the base reaches a level at which it obturates the mouth of the nozzle, preventing the air to enter the tank and keeping the water in the tank.
Claim 23
Dependent Claim
41 words
A device as claimed in claim 21, in which the tank is split in two halves and attached to existing pots of the suitable size, either by anchoring each half -to the pot or by anchoring the two halves between them.
Claim 24
Dependent Claim
37 words
A device as claimed in claim 22, in which each half is provided with its own nozzle and a spacer, to ensure a certain distance between the mouth of the nozzle and the bottom of the base.
Claim 25
Dependent Claim
41 words
A device as claimed in claim 21, in which the nozzle is provided with a slider or a flap which obturates the nozzle while the tank is turned up-side-down in order to prevent the water from pouring out during this operation.
Claim 26
Dependent Claim
77 words
A device as claimed in claim 1 in which the tank can be attached to existing pots of any size or form by anchoring it to the pot by means of a slide provided at the upper end with a hanger and which said slide can move in a sliding guide which is part of the body of the tank, permitting in this way the anchoring of a tank of one size to pots of different sizes.
Claim 27
Dependent Claim
80 words
A device as defined in claim 25, in which the automatic level control means is composed of a single nozzle of a larger diameter through which the water flows out of the tank into the plate, and air enters the tank to replace the water, until the water in the base reaches a level at which it obturates the mouth of the nozzle preventing the air to entering the tank, and in this way keeping the water in the tank.
Claim 28
