S~ECIFICA~ION
_ This invention i9 concerned with the automatic watering of interior or exterior plants or flowers grown in pots,which mu~t be artificially supplied with water by human intervention.
The growing of plants or flowers in pots,as a natural decoration is extremely spread all over the world. A difficulty in their co rrect maintenence is the necessity to water them frequently,every day or eYery few days,in such a rnenner as to maintain in the earth a rather constant humidity. The lack or the excess of water,not only may harm the plants or flowers,but in many cases may destroy them. This difficulty becomes much more significant when one have to leave the house for a longer while,like in week-ends,vacations, etc.
The idea of the present invention is to overcome this difficulty by designing a new type of pot for plants or flowers,provided with a reservoir (tank) and a device which is able to supply automatically ~act~y the amount o~ water consumed by the plants or lost in eva-poration,maintaining in this way a constant humidity in the earth, regardless the external conditions (air temperature and humidity), for a long period of time. ~his period of time is,for proportionate tanks (related to the pots),about two months. The tanks can be sized yet for any period of time or for special conditions ~ t has to be mentioned that the idea is not new,but this invention presents functional,simple and technological solutions which differ in man~ respects from other inventions patented up to now,which are characterised by rnore complicated,heavy and non-technological so-lutions or by functional limitations.

_~_ The embodiment il~ustrated in fig.1,eolnprisc~ t~Je pot 1,which ~is the container of the earth in which the plants or flowers are planted~the tank 4,which con-tains the water,the plate 3,and the water level control deuice,which in this embodirnent is composed of the double nozzle 8,the ball 8.2,and the lirniter 8.3.
The pot may have the usua] shape of a truncated cone,as illustra-ted in fig.1,or any other ahape,and is provided at the bottom with the orifices 1.1 through the water can penetrate inside. It may be made of plastic or other suitable materials and it may be provided with the handles 2 whichhelp to extract the pot from the tank.
~ he tank is made of plastic or any other impermeable material,and may have any shape~ Yet,the shape proposed by this invention,as illu-strated in fig.1 and 3,is the cubic one,which ensures the best ratio between the stored volume of water and the overall size. In one of the external walls of -the tank,is ernbodied the transparent stripe 5 which allows the assesrnen-t of the level inside the tank. An alterna-tive could be a transparent tube 5,as illustrated in fig.2,ti~htly inserted in the tank at upper and lower side of the wall. At the upper side the tank is provided with the plug 6 w~lich closes ti~htly the tank by means of the rubber ring 7. The internal wall is provided with the spacers 4.19which guide the pot and provide a gap through which the air fro~. outside can reach the water surface in the plate 3, The double nozzle 8,is provided with a short,calibrated orifice 8.1,through which the water stored in the tank flows in the plate 3, and a larger orifice 8.4 obturated with the ball 8.2 which is just a little heavier than the volume of water it replaces. The ball is pre-vented to leave the nozzle by the limiter 8.3. Through the orifice 8.4 the air enters the tank to replace the water discharged into the plate 3. The plate 3,made of the same material as the tank,on which both the pot and the tank are seated,is provided with ~he spacers 3.1 which facilitate the water to pene-trate under the pot 1.
The device works as follows:
A plan-t or a f]ower planted in the pot,sucks water from the earth according to its kind,size and environamental conditions such as air temperature and humidity. The best waterin~ i9 obtained when the water is suplled from the bottoM of the pot,if it is mantained at a constant low level,under the ends of the roots. In this case,the 1 1 ~6~
earth absorbs from t~le plate only as rnuc~ Jater .lS t;~e ,~,larlt or flower sucks from it,keeping a perfect constant humidity.
In the present invention~the earth in the pot absorbs water from the ~late 3,through the holes 3.1 provided at the bottom of the pot~
The water in the plate iB supplied ~rom the reservoir 4 which can store water for a long period of tirne (fur a proportionate tank and an avera~e plant,around two months). The lar~e capacit~ of the tank according to this invention is due to it~ cwbic shape which en-sures the best ratio between the size of the tank and the amount of water stored in it. The level of the water in the plate 3, i8 main-tained constant,at the optimum height,regardless the plant consum-tion,the evaporation or the level of the water in the tank. This is ensured by the nozzle 8. The water flows through the orifice 8.1, only as long as,the surface "A" of the nozzle (see fig.1) is not submerged in the water. When the water in the plate 3 reaches the surface "A",the access of the air into the tank through the orifice 8.4,to replace the water flowed out of the tank,is blocked,and the atmospheric pressure keeps the water in the tank. When the level of the water in the plate 3 decreases,due to the consumption in the pot or evaporation,the access of the air into the tank is ensured a~ain, and the water from the tank 4 will flow a~ain into the plte 3,until the water in the plate reaches the surface "A", when the access of the air into the tank is blocked a~ain. This cyclic process continues automaticallyuntil the tank is emptied.
The refiling of the tank 4 with water is accomplished through the orifice 4.2 b~ removing the plug 6. During the refilling,the air can enter free the tank through the orifice 4q2,so that all this time, the water will flow through the orifice 8.1 of the nozzle 8,into the plate 3. Therefore the orifice 8.1 is calibrated in such a manner that during a normal time of refillin~,the level of water in the plte 3 to increase insignificantly. The larger orifice 8.4 is blocked by the ball 8.2.-After the refîlling ,the plug 6 should be screwed tightly,to prevent the access of air into the tank. This is rnade possible by means of the rubber ring 7.
The level of the water in the tank may be observed through -the transparent stripe or tube 5.
The hangers 2 facilitate an eas~ removal of the pot.
6 ~
~ i~.3 illustrltes a per.spective view of t~e em~~odiment deQ,cribe(3 above.
The embodiment illustra-te~ in fig.4 is a conatructive alternative of the embodimen-t described above, According to this alternative,the noæzle 8 ls inserted in a vertical wall,and the orifices 8.1 and 8.4 have the shape of 1~7~ as illugtrated in fiK.4 and6. The ball 8~2 is replaced with a flap. ~hi8 alternative vorks identically with the one illustrated in fig. 1,2 and 3.
~ he embodiment illustrated in fig.7 is another construc~ive alter-native, In this alternative the factor"fillir~g time2 i5 no more involved. The nozzle 8 has only one larger orifice which may be a part of the tank wa~. The plug 11 is pressed against the surface "A" of the nozzle~by the spring 1C. The plug 6 is provided with the rod 12 which length is such,that when the plug 6 is screwe~ ti~htly the end of the rod pushes down -the plug 11 and keeps the orifice open. ~rom now on this alternative wo-rks identically with the other ones described before,~he only difference being that the water flows from the tank,and the air enters into the tank to replace it,through the same larger orifice. The calibration is no more necessary,because during the refilling,the nozzle 8 is obturated by the plug 11,and the water is kept in the tank regardless the t~nk is connected with the atmospheric pressure. When one wants to refill the tank with water and screws out the plug 6,the rod 12 does no-t push down any more the plug 11.and the spring 10 pushes it up obturating the nozzle. Thus the refilling time may be indefinite. The plug 11 is guided in the nozzle 8 by the legs 11~1t The embodiment illustrated in fig.8 is another constructive al-ternative of the invention in which the "filling time" is not in-volved. In this alternative,the level control device is composed~
of the nozzle 14 with the arm 14.1,the plug 16 and the floater 18.
The floater 18 is articulated through its arm 18.1 to the arm 14.1 of the nozzle 14,by means of the peg 15. The plug 16 is articulated to the arm 18.1 of the floater 18 bv means of the peg 17. When the level of the water in the plate 3 increases, the floater 18 pushes 1 15B~;4 the plug 16 up against the nozzle 14,obturating the orifice through ~hich the water stored in the tank flows in the plate and the air from outside enters the tank to replace it, When the level of the water in the plate decreases,the floater controlling the plug 16 opens ~he nozæle 14 and brings again the water into the plate. This cyclic process continues until the tank is emptied, This alternative works regardless the plug 6 is closed tightly or not.
lhe embodiment illustrated in fig.9 is another constructive alter-native of the invention which can be used for small pots. In this alternative,which is the simplest7the tank 4 is filled through the nozzle 8,which is in the same time the level control device. To fill the tank,the pot must be first taken out. lhe tank filled with water is turned up side down,the nozzle 8 being kept obturated with a finger,and seated on the plate 3. After that the pot can be seated again on the plate,and by this the de~ice is already in operation.
~he water stored in the tanX flows out into the plate ~ until the level of the water in the plate reaches the surface "A"~ In this moment,identically as in the embodiments illustrated in fig. 1,4 and 7,the air is prevented entering the tank to replace the water,and the atmospheric pressure keeps the water in the tank. When the level in the plate 3 decreases due to the consumption in the pot or eva-poration,the nozzle 8 is de-obturated,the air can enter the tank again to cancel the created vacuum and to release the water to flow again into the plate 3. ~his cyclic process continues automatically until the tank 4 is emptied.
~ he embodiment illustrated in fig.10 is a constructive alterna-tive of the embodiment illustrated in fig.9,that can be used for narrow plants (as cactus). In this alternative,the pot and the in-terior wall of the tank being cylindrical,the tank can be removed from the plate without disturbing the pot.It works identiclly as the embodiment illustrated in fig.9.
lhe embodiment illustrated in fig.11 is another constructive alternative of the embodiment illustrated in fig.9,which may be used also for existing pots. In this alternative the tank 4 is split in two symetrical halfs. One half can be used also independently.
The noz~le 8 m~y be ~ike in t~le embodinlent illust-rated in fig.
-art of the tank wall. It may }~ave variou~ ~hape~,.like the one~
illustrated in fig. 12 and 13. After the f}llinK,the nozzle may be obturated with a finger (for preventing the water to ~low out w~len the tank is turned up side down~,ox with a ~lide like the o~e shown in fig~11 (pos.20) which can be removed by mean~ of the thread 22.
The tanks are provided al~o with the legs 21 which can be cut at the necessary length for ensuring the desired level of water in the plate. The tanks may be attached to the pot by means of the hanger 19,as shown in fig.14 and 15,or attached between them by means of the hanger 23 as shown in fig.14 and 16.
~ he embodi~ent illustrated in fig.17 is another constructive alternative of the invention which may be adapted to existing pots of any form or size. In this alternative,the tank,which may be of any shape (in fig.18 is illustrated as a cylinder) is provided with the sliding guide 4 3 and the slide 24 as shown in fig. 17,18 and 190 The slide i3 provided at the upper side with the hanger 24.1 by means of which the tank is hanged to the pot. ~y m~ving the slide in the sliding guide,the tank can be attached to a pot of any size.
The operation of the device in -this alternative is i2entical with the ones illustrated in fig. 9,10 and 11. During the turning up-side down of the tank after refilling,the nozzle 8 may be obturated either with ~ finger or by a slider like in fig.11 and13,or by a flapper,like posO25 in fig.20.
~ he embodiment illustrated in fig. 21 i~ another constructive alternati~e of the invention,which can be used for more existent pots simoultaneously. In this alternative,the pots seated on a co-mmon plate are supplied by a common tank 4 provided with the legs 21,which length defines the level of the water in the plate,and the nozzle 8 through wh~ch the water from the tank flows into the plate and the air from outside enters the tank to replace the water.
~ e operation of the device in this alternative is identical with the operation of the devices illustrated in fig.9,1~,11 and 17.
~ he embodiment illustrated in fig.24 is another constructive alternative of the invention based on a different principle. ~his embodiment is a centralised system for watering more pots simoulta-neously,even if the pots are located at differer,t h~i~hts. In thisembodiment,the water from the tank '~1 ,iR pumped by the pump 34, through the tube 3Q,distri~utor 35 and flexible tubes ~6 to the bulbs 37. ~he pump which preferably may be a mernbrane pump,is controlled by the pressure switch 38 and the 'buffer 39, which measure the pressure in the distributor. ~he pressure .switch may be composed of the diaphragm 38.1,the plate 38.8,the ~pring 38.2 which force can be adjusted by the screw 38,3,the switches 38,4 and 38.5~the orifices 38.6 and 38.8,which make connection with the pump and the buffer respectively,and the guide plate 38.9.
The pump and the pressure switch in themselves are not part of the present invention.
~ he bulb 37 is illustrated iD fig.25-28. The bulb shown in fig.
25 is designed to be implanted directly in the pot. It is composed of the body 37.1 provided with a longitudinal orifice 37~,the seat 37.8,the plug 37.2 inserted in the floater 37.4 and guided by the guide 37.5,the floater chamber 37.6 provided with inclined holes, and the lid 37.7 tightens the flexible tube 36 to the body. The bulb shown in fig.27 is designed to be implanted in the plate out-side -the p~ he difference against the bulb shown in fig.25 is that the floater 37.4 is horisontal and is articulated by means of ~he rod 37~9 to the charnber 37.6 which has the shape shown in fig.
27 and 28. ~he plug 37.2 is not actuated directly by the floater 37.4 but by the rod 37.9 In ~ fig.29 is illustrated another constructive alternative of the bulb shown in fig.27,which is attached to a new designed pot. A top view of this pot is shown in fig. ~0.
The system illustrated in fig.24-30 works as follows:
The pump 34,pumps the water sucked from the bottom of the tank 31 through the tube 32,the distributor 35 and the flexible tubes 36 to the bulbs 37. ~hrou'gh the bulbs 37,the water flows in the pots or in the plates in which they are implanted, If the level of the water in a pot or in a plate.~n-~r~a~es d~e~-to ~he:~h~ t~ r the floater 37.4 rises and pushes up the plug 37.2,obturating in this way,the access into the respective pot or plate df the water pumped by the pump 34. The water continues to be pumped into -the 1 ~ 5~
other pots or plates in which the level of the water i~ still low~
,If the level in all the pots or plates is high,so that the access of water in all bulbs is obturated,the purnp 34 begins to compress the air in the buffer 39. 'l'he increa~ing pressure in the sy~tem i8 measured by the membrane 38,1 of the pres3ure switch 3~ against the spring 38.2. When the pressure in the system reaches a predetermina-ted value,the plate 38.8 fixed to the membrane actuates the ~witch 38.5 which stops the pump 34. The buffer ~9 haa the role to compen-sats for the eventual small leakages in the system. When the level in one of the pots or plates decreases,the air from the buffer pu~
shes the water out and the pres~ure in the system decrea~es as well.
At a certain low value of the pressure in the system,the pressure switch 38 start~ the pump 34 again. When the water level in the pot or plate increases,the respective bulb obturates again the access of the water in the pot or plate,and the pressure in the system begins again to increase,ca~sing eventually -~he shut down of the pump. ~his cyclic process continues automatically un~il the tank 31 is emptied.
It must be noticed that if the water level is low in more pots or plates in the same time,the pump starts when the first bulb de-obtu-rates and stops after the last bulb obturates. That means that the pump runs as long as the water level is low at least in one pot or plate,and is shut down water level is high in all the pots or plates.
It must be noticed also that the system works with the bulbs,that means the pots or plates,located at different levels. The pressure at which the pump is started is dictated by the highest one,and can be adjusted by the screw 38~3 of the pressure switch.
~he bulbs,illustrated in fig.25 and 27,work as follows:
~ he water pumped by the pump 31 flows through the ori~ice 37.3, the seat 37.8,the orifices 37.11 of the guide 37.5 and the holes 37.12 of floater chamber,into the earth in which the bulb is implan-ted. When the water le~el in the floater chamber 37.6 which is the same as in the pot,is high,the floater ~7.4 pushes up the plug 37.2 against the seat 37.8 and closes the access of the water down into the chamber 37.6 and from here into the earth.It mu~t be noticed that the bulb illustrated in fig.25 is limited by the relative small obturating force that can be exercited by the small vertica1 ~loater permited by thi~ construction. Therefore it may be u~ed mostly ~or ~the pots located at the ~ame le~el. The con~truction shown in ~ig.
27 and 2g eliminate~ thi~ ~ho:rtcoming by using a larger,horizontal floater,and e~pecially a much bigger fo.rce ampllflcation~
R~garding the con~truction from fig.~5 it must be noticed that the inclination of the holes 37.12 and of the exter~al wall~ of the floater chamber above the holes,en~ures that the earth not to pene-trate into the floater chamber neither when the bulb is implanted in the earth nor when is extracted from the pot.

_~_ The embodiment il~ustrated in fig.1,eolnprisc~ t~Je pot 1,which ~is the container of the earth in which the plants or flowers are planted~the tank 4,which con-tains the water,the plate 3,and the water level control deuice,which in this embodirnent is composed of the double nozzle 8,the ball 8.2,and the lirniter 8.3.
The pot may have the usua] shape of a truncated cone,as illustra-ted in fig.1,or any other ahape,and is provided at the bottom with the orifices 1.1 through the water can penetrate inside. It may be made of plastic or other suitable materials and it may be provided with the handles 2 whichhelp to extract the pot from the tank.
~ he tank is made of plastic or any other impermeable material,and may have any shape~ Yet,the shape proposed by this invention,as illu-strated in fig.1 and 3,is the cubic one,which ensures the best ratio between the stored volume of water and the overall size. In one of the external walls of -the tank,is ernbodied the transparent stripe 5 which allows the assesrnen-t of the level inside the tank. An alterna-tive could be a transparent tube 5,as illustrated in fig.2,ti~htly inserted in the tank at upper and lower side of the wall. At the upper side the tank is provided with the plug 6 w~lich closes ti~htly the tank by means of the rubber ring 7. The internal wall is provided with the spacers 4.19which guide the pot and provide a gap through which the air fro~. outside can reach the water surface in the plate 3, The double nozzle 8,is provided with a short,calibrated orifice 8.1,through which the water stored in the tank flows in the plate 3, and a larger orifice 8.4 obturated with the ball 8.2 which is just a little heavier than the volume of water it replaces. The ball is pre-vented to leave the nozzle by the limiter 8.3. Through the orifice 8.4 the air enters the tank to replace the water discharged into the plate 3. The plate 3,made of the same material as the tank,on which both the pot and the tank are seated,is provided with ~he spacers 3.1 which facilitate the water to pene-trate under the pot 1.
The device works as follows:
A plan-t or a f]ower planted in the pot,sucks water from the earth according to its kind,size and environamental conditions such as air temperature and humidity. The best waterin~ i9 obtained when the water is suplled from the bottoM of the pot,if it is mantained at a constant low level,under the ends of the roots. In this case,the 1 1 ~6~
earth absorbs from t~le plate only as rnuc~ Jater .lS t;~e ,~,larlt or flower sucks from it,keeping a perfect constant humidity.
In the present invention~the earth in the pot absorbs water from the ~late 3,through the holes 3.1 provided at the bottom of the pot~
The water in the plate iB supplied ~rom the reservoir 4 which can store water for a long period of tirne (fur a proportionate tank and an avera~e plant,around two months). The lar~e capacit~ of the tank according to this invention is due to it~ cwbic shape which en-sures the best ratio between the size of the tank and the amount of water stored in it. The level of the water in the plate 3, i8 main-tained constant,at the optimum height,regardless the plant consum-tion,the evaporation or the level of the water in the tank. This is ensured by the nozzle 8. The water flows through the orifice 8.1, only as long as,the surface "A" of the nozzle (see fig.1) is not submerged in the water. When the water in the plate 3 reaches the surface "A",the access of the air into the tank through the orifice 8.4,to replace the water flowed out of the tank,is blocked,and the atmospheric pressure keeps the water in the tank. When the level of the water in the plate 3 decreases,due to the consumption in the pot or evaporation,the access of the air into the tank is ensured a~ain, and the water from the tank 4 will flow a~ain into the plte 3,until the water in the plate reaches the surface "A", when the access of the air into the tank is blocked a~ain. This cyclic process continues automaticallyuntil the tank is emptied.
The refiling of the tank 4 with water is accomplished through the orifice 4.2 b~ removing the plug 6. During the refilling,the air can enter free the tank through the orifice 4q2,so that all this time, the water will flow through the orifice 8.1 of the nozzle 8,into the plate 3. Therefore the orifice 8.1 is calibrated in such a manner that during a normal time of refillin~,the level of water in the plte 3 to increase insignificantly. The larger orifice 8.4 is blocked by the ball 8.2.-After the refîlling ,the plug 6 should be screwed tightly,to prevent the access of air into the tank. This is rnade possible by means of the rubber ring 7.
The level of the water in the tank may be observed through -the transparent stripe or tube 5.
The hangers 2 facilitate an eas~ removal of the pot.

~ i~.3 illustrltes a per.spective view of t~e em~~odiment deQ,cribe(3 above.
The embodiment illustra-te~ in fig.4 is a conatructive alternative of the embodimen-t described above, According to this alternative,the noæzle 8 ls inserted in a vertical wall,and the orifices 8.1 and 8.4 have the shape of 1~7~ as illugtrated in fiK.4 and6. The ball 8~2 is replaced with a flap. ~hi8 alternative vorks identically with the one illustrated in fig. 1,2 and 3.
~ he embodiment illustrated in fig.7 is another construc~ive alter-native, In this alternative the factor"fillir~g time2 i5 no more involved. The nozzle 8 has only one larger orifice which may be a part of the tank wa~. The plug 11 is pressed against the surface "A" of the nozzle~by the spring 1C. The plug 6 is provided with the rod 12 which length is such,that when the plug 6 is screwe~ ti~htly the end of the rod pushes down -the plug 11 and keeps the orifice open. ~rom now on this alternative wo-rks identically with the other ones described before,~he only difference being that the water flows from the tank,and the air enters into the tank to replace it,through the same larger orifice. The calibration is no more necessary,because during the refilling,the nozzle 8 is obturated by the plug 11,and the water is kept in the tank regardless the t~nk is connected with the atmospheric pressure. When one wants to refill the tank with water and screws out the plug 6,the rod 12 does no-t push down any more the plug 11.and the spring 10 pushes it up obturating the nozzle. Thus the refilling time may be indefinite. The plug 11 is guided in the nozzle 8 by the legs 11~1t The embodiment illustrated in fig.8 is another constructive al-ternative of the invention in which the "filling time" is not in-volved. In this alternative,the level control device is composed~
of the nozzle 14 with the arm 14.1,the plug 16 and the floater 18.
The floater 18 is articulated through its arm 18.1 to the arm 14.1 of the nozzle 14,by means of the peg 15. The plug 16 is articulated to the arm 18.1 of the floater 18 bv means of the peg 17. When the level of the water in the plate 3 increases, the floater 18 pushes 1 15B~;4 the plug 16 up against the nozzle 14,obturating the orifice through ~hich the water stored in the tank flows in the plate and the air from outside enters the tank to replace it, When the level of the water in the plate decreases,the floater controlling the plug 16 opens ~he nozæle 14 and brings again the water into the plate. This cyclic process continues until the tank is emptied, This alternative works regardless the plug 6 is closed tightly or not.
lhe embodiment illustrated in fig.9 is another constructive alter-native of the invention which can be used for small pots. In this alternative,which is the simplest7the tank 4 is filled through the nozzle 8,which is in the same time the level control device. To fill the tank,the pot must be first taken out. lhe tank filled with water is turned up side down,the nozzle 8 being kept obturated with a finger,and seated on the plate 3. After that the pot can be seated again on the plate,and by this the de~ice is already in operation.
~he water stored in the tanX flows out into the plate ~ until the level of the water in the plate reaches the surface "A"~ In this moment,identically as in the embodiments illustrated in fig. 1,4 and 7,the air is prevented entering the tank to replace the water,and the atmospheric pressure keeps the water in the tank. When the level in the plate 3 decreases due to the consumption in the pot or eva-poration,the nozzle 8 is de-obturated,the air can enter the tank again to cancel the created vacuum and to release the water to flow again into the plate 3. ~his cyclic process continues automatically until the tank 4 is emptied.
~ he embodiment illustrated in fig.10 is a constructive alterna-tive of the embodiment illustrated in fig.9,that can be used for narrow plants (as cactus). In this alternative,the pot and the in-terior wall of the tank being cylindrical,the tank can be removed from the plate without disturbing the pot.It works identiclly as the embodiment illustrated in fig.9.
lhe embodiment illustrated in fig.11 is another constructive alternative of the embodiment illustrated in fig.9,which may be used also for existing pots. In this alternative the tank 4 is split in two symetrical halfs. One half can be used also independently.
The noz~le 8 m~y be ~ike in t~le embodinlent illust-rated in fig.
-art of the tank wall. It may }~ave variou~ ~hape~,.like the one~
illustrated in fig. 12 and 13. After the f}llinK,the nozzle may be obturated with a finger (for preventing the water to ~low out w~len the tank is turned up side down~,ox with a ~lide like the o~e shown in fig~11 (pos.20) which can be removed by mean~ of the thread 22.
The tanks are provided al~o with the legs 21 which can be cut at the necessary length for ensuring the desired level of water in the plate. The tanks may be attached to the pot by means of the hanger 19,as shown in fig.14 and 15,or attached between them by means of the hanger 23 as shown in fig.14 and 16.
~ he embodi~ent illustrated in fig.17 is another constructive alternative of the invention which may be adapted to existing pots of any form or size. In this alternative,the tank,which may be of any shape (in fig.18 is illustrated as a cylinder) is provided with the sliding guide 4 3 and the slide 24 as shown in fig. 17,18 and 190 The slide i3 provided at the upper side with the hanger 24.1 by means of which the tank is hanged to the pot. ~y m~ving the slide in the sliding guide,the tank can be attached to a pot of any size.
The operation of the device in -this alternative is i2entical with the ones illustrated in fig. 9,10 and 11. During the turning up-side down of the tank after refilling,the nozzle 8 may be obturated either with ~ finger or by a slider like in fig.11 and13,or by a flapper,like posO25 in fig.20.
~ he embodiment illustrated in fig. 21 i~ another constructive alternati~e of the invention,which can be used for more existent pots simoultaneously. In this alternative,the pots seated on a co-mmon plate are supplied by a common tank 4 provided with the legs 21,which length defines the level of the water in the plate,and the nozzle 8 through wh~ch the water from the tank flows into the plate and the air from outside enters the tank to replace the water.
~ e operation of the device in this alternative is identical with the operation of the devices illustrated in fig.9,1~,11 and 17.
~ he embodiment illustrated in fig.24 is another constructive alternative of the invention based on a different principle. ~his embodiment is a centralised system for watering more pots simoulta-neously,even if the pots are located at differer,t h~i~hts. In thisembodiment,the water from the tank '~1 ,iR pumped by the pump 34, through the tube 3Q,distri~utor 35 and flexible tubes ~6 to the bulbs 37. ~he pump which preferably may be a mernbrane pump,is controlled by the pressure switch 38 and the 'buffer 39, which measure the pressure in the distributor. ~he pressure .switch may be composed of the diaphragm 38.1,the plate 38.8,the ~pring 38.2 which force can be adjusted by the screw 38,3,the switches 38,4 and 38.5~the orifices 38.6 and 38.8,which make connection with the pump and the buffer respectively,and the guide plate 38.9.
The pump and the pressure switch in themselves are not part of the present invention.
~ he bulb 37 is illustrated iD fig.25-28. The bulb shown in fig.
25 is designed to be implanted directly in the pot. It is composed of the body 37.1 provided with a longitudinal orifice 37~,the seat 37.8,the plug 37.2 inserted in the floater 37.4 and guided by the guide 37.5,the floater chamber 37.6 provided with inclined holes, and the lid 37.7 tightens the flexible tube 36 to the body. The bulb shown in fig.27 is designed to be implanted in the plate out-side -the p~ he difference against the bulb shown in fig.25 is that the floater 37.4 is horisontal and is articulated by means of ~he rod 37~9 to the charnber 37.6 which has the shape shown in fig.
27 and 28. ~he plug 37.2 is not actuated directly by the floater 37.4 but by the rod 37.9 In ~ fig.29 is illustrated another constructive alternative of the bulb shown in fig.27,which is attached to a new designed pot. A top view of this pot is shown in fig. ~0.
The system illustrated in fig.24-30 works as follows:
The pump 34,pumps the water sucked from the bottom of the tank 31 through the tube 32,the distributor 35 and the flexible tubes 36 to the bulbs 37. ~hrou'gh the bulbs 37,the water flows in the pots or in the plates in which they are implanted, If the level of the water in a pot or in a plate.~n-~r~a~es d~e~-to ~he:~h~ t~ r the floater 37.4 rises and pushes up the plug 37.2,obturating in this way,the access into the respective pot or plate df the water pumped by the pump 34. The water continues to be pumped into -the 1 ~ 5~
other pots or plates in which the level of the water i~ still low~
,If the level in all the pots or plates is high,so that the access of water in all bulbs is obturated,the purnp 34 begins to compress the air in the buffer 39. 'l'he increa~ing pressure in the sy~tem i8 measured by the membrane 38,1 of the pres3ure switch 3~ against the spring 38.2. When the pressure in the system reaches a predetermina-ted value,the plate 38.8 fixed to the membrane actuates the ~witch 38.5 which stops the pump 34. The buffer ~9 haa the role to compen-sats for the eventual small leakages in the system. When the level in one of the pots or plates decreases,the air from the buffer pu~
shes the water out and the pres~ure in the system decrea~es as well.
At a certain low value of the pressure in the system,the pressure switch 38 start~ the pump 34 again. When the water level in the pot or plate increases,the respective bulb obturates again the access of the water in the pot or plate,and the pressure in the system begins again to increase,ca~sing eventually -~he shut down of the pump. ~his cyclic process continues automatically un~il the tank 31 is emptied.
It must be noticed that if the water level is low in more pots or plates in the same time,the pump starts when the first bulb de-obtu-rates and stops after the last bulb obturates. That means that the pump runs as long as the water level is low at least in one pot or plate,and is shut down water level is high in all the pots or plates.
It must be noticed also that the system works with the bulbs,that means the pots or plates,located at different levels. The pressure at which the pump is started is dictated by the highest one,and can be adjusted by the screw 38~3 of the pressure switch.
~he bulbs,illustrated in fig.25 and 27,work as follows:
~ he water pumped by the pump 31 flows through the ori~ice 37.3, the seat 37.8,the orifices 37.11 of the guide 37.5 and the holes 37.12 of floater chamber,into the earth in which the bulb is implan-ted. When the water le~el in the floater chamber 37.6 which is the same as in the pot,is high,the floater ~7.4 pushes up the plug 37.2 against the seat 37.8 and closes the access of the water down into the chamber 37.6 and from here into the earth.It mu~t be noticed that the bulb illustrated in fig.25 is limited by the relative small obturating force that can be exercited by the small vertica1 ~loater permited by thi~ construction. Therefore it may be u~ed mostly ~or ~the pots located at the ~ame le~el. The con~truction shown in ~ig.
27 and 2g eliminate~ thi~ ~ho:rtcoming by using a larger,horizontal floater,and e~pecially a much bigger fo.rce ampllflcation~
R~garding the con~truction from fig.~5 it must be noticed that the inclination of the holes 37.12 and of the exter~al wall~ of the floater chamber above the holes,en~ures that the earth not to pene-trate into the floater chamber neither when the bulb is implanted in the earth nor when is extracted from the pot.
