rLowERPo'T Filed Jan. 27, 1940 I In ventor Call/2'22 l .Blumezfizz? Attorneys Patented July 7, 1942 UNITED STATE 5 PATENT or F1 or:

2,288,678 'FLOWEItPOT Calvin L. Blumentritt, Winona, Minn. I Application January27, 1940, Serial No. 316,039 5 Claims. '(ol. 47-38) The present invention relates to new and useful improvements in flower pots, and has for its primary object to provide a device of this char acter wherein a predetermined water level is maintained in the same for supplying moisture to the plant,

Another object of the invention is to provide a reserve supply of water which may be entirely consumed while during the consumption of the same a substantial head of water is maintained in the plant holding compartment.

Another object of the invention is to provide a flower pot wherein water is supplied thereto automatically.

Still other objects and advantages of the invention will become apparent from a study of the following detailed description taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a side elevational View of my invention.

Figure 2 is a top and Figure 3 is a vertical sectional view taken substantially on the line 3--3 of Figure l.

Referring now to the drawing in detail, it will be seen that the reference numeral 5 designates plan view of the invention,

generally a double walled receptacle constructed preferably of sheet metal, but any suitable material may be employed.

The open plant receiving receptacle 6 of the double walled receptacle 5 is similar to a conventional flower pot in that it has a flanged top portionl. The bottom side 8 is flanged at 9 and further has an opening I therein in which is mounted a vent 0r overflow tube II.

Surrounding the receptacle 6 and soldered or otherwise secured to the periphery of the flanges 'I and 9 is a wall I2 which forms an annular compartment I3 between the wall and the receptacle 6. The compartment I3 communicates with interior of the receptacle 6 by means of a small orifice I4.

Extending through the compartment I3 and flange top portion I is a small vent tube I having an opening I6 near the bottom'end thereof.

The compartment I3 is filled with water through a neck I! which is closed air tight with a threaded cap I8. 7

The operation of the device is as follows:

When the compartment I3 is to be filled with water, the cap I8 is removed and water is poured through the neck II into the compartment I3 at which time a portion of the water will enter the tube I5 through the opening I6 and define a level equal with that in the compartment I3, and a portion of the water will pass through the opening I4 and enter the receptacle 6. When the compartment I3 is full the cap I8 is replaced. When the cap I8 is replaced the water level in the tube I5 will drop to a level defined by the water level in the receptaclefi where the two levels will be balanced by atmospheric pressure due to the fact that tube I5 and the receptacle 6 communicate with each other. When the cap I8 is in place and the water level in the receptacle 6 lowers due to evaporation, or other reasons, the water level in the tube I5 will lower correspondingly to such an extent as to permit air to descend through the tube I5 and pass through the opening I6, thence bubble up through the water in the compartment I3 and displace a portion of the water in the compartment I3 which portion passes through the opening I4 into the receptacle 6 and raises the water level therein. Then the water level in the com-' partment 6 again rises with a corresponding rise of the water level in the tube I5 until the passage of air in the tube [5 is again prohibited.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials and in the structure and arrangement of the parts within the spirit of the invention as claimed.

What is claimed is:

l. A flower pot including a liquid reservoir which forms a part of said pot, said reservoir having means for communicating with said pot, and a vent tube having a side opening at its bottom end portion housed in said reservoir for controlling the level of liquid in said pot.

2. A flower pot having a flanged top, a bottom for said pot having a flange thereon, a wall connectingsaid flanges to provide a liquid reservoir about said pot, said pot having an inlet therein for the passage of said liquid thereto from said reservoir, and a vent tube housed within said reservoir and extending from the top thereof, said tube having an opening spaced from the bottom end thereof for controlling the flow of said liquid from said reservoir into said pot.

3. A flower pot having a flanged top portion, a bottom for said pot having a flange thereon, a Wall spaced from said pot and connecting said flanges to provide a liquid reservoir about said pot, said pot having means therein for communicating with said liquid reservoir, a vent tube in said reservoir, said vent tube having means for maintaining the liquid level in said pot above the communication means between said pot and liquid reservoir.

4. A flower pot including a plant-holding compartment and a sealed liquid-holding compartment having communication means at the bottom end portions thereof, a tube vertically mounted in said sealed liquid compartment with its top end portion extending from said sealed compartment, and said tube having means in its bottom end portion for maintaining a liquid level in said plant-holding compartment above the communication means between said plantholding compartment and said sealed liquidholding compartment.

5. A flower pot including a plant-holding compartment, a sealed liquid-holding compartment, said compartment having communication means between them, and means housed in said liquidholding compartment for maintaining a liquid level in said plant-holding compartment a predetermined distance above said communication means.
