Description
Background of the Invention
Various forms of containers for fertilizer have been heretofore designed for positioning nearby and fertilizing, by leaching action, ground plants each time a rainfall is experienced. However, most of these previously known devices have been designed for embedding in the ground and are thus subject to flooding as a result of heavy rains.
Examples of previously patented ground plant fertilizing devices as well as other devices including some of the general structural and operational features of the instant invention are disclosed in U.S. Pat. No. 1,778,030, 1,992,878, 2,145,934, 3,188,771, 3,243,919 and 3,821,863.
Brief Description of the Invention
The tree and shrub feeder of the instant invention has been designed for placement on the ground about a grounded plant to be fertilized by leaching action in response to rainfall. In addition, the feeder is constructed in a manner whereby it presents a pleasing aesthetic appearance and also includes structure whereby it will not be flooded by a heavy rainfall so as to cause either over feeding of an associated ground plant or wasteful complete dissolving of the fertilizer contained therein.
The main object of this invention is to provide a ground plant feeder which will be capable of dispensing predetermined quantities of dissolved water-soluble fertilizer in proportion to the amount of rainfall each time it rains.
Another object of this invention, in accordance with the preceding object, is to provide a ground plant feeder for containing water-soluble fertilizer and including structural features which will substantially eliminate flooding of the feeder as a result of a heavy rain.
Still another very important object of this invention is to provide a feeder in which a supply of water-soluble fertilizer may be readily replenished.
A further object of this invention is to provide a feeder in accordance with the preceding objects and which is adapted to be placed on the surface of the ground adjacent a plant to be fed.
Still another object of this invention is to provide a feeder in accordance with the preceeding object and which will present a pleasing aesthetic appearance.
A final object of this invention to be specifically enumerated herein is to provide a feeder which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Detailed Description of the Invention
Referring now more specifically to the drawings, the numeral 10 generally designates a tree and the numeral 12 generally designates the ground from which the tree 10 is growing.
A pair of feeders constructed in accordance with the present invention are generally designated by the reference numerals 14 and are positioned on the ground 12 on opposite sides of the tree 10. Although the feeders 14 are illustrated in closely spaced relation relative to the tree 10 it is to be understood that the feeders 14 will be normally placed considerably outwardly from the tree 10 and that more than two feeders 14 may be used to feed the tree 10.
Referring now more specifically to FIGS. 2 and 3 it may be seen that the feeder 14 of the instant invention includes an outer receptacle referred to in general by the reference numeral 16 including upstanding side wall portions 18 and closed at its lower end by means of a bottom wall 20. The feeder 14 also includes an inner receptacle referred to in general by the reference numeral 22 including upstanding side wall portions 24 and closed at its bottom by means of a bottom wall 26.
The open upper end of the inner receptacle 22 includes radially inwardly deflected upper marginal portions 28 defining outwardly opening recesses 30 spaced about the receptacle 22. The receptacle 22 may be initially constructed so as to be of circular cross section throughout its entire height and may then have its upper marginal portions inwardly deflected as at 28. The receptacle 22 is preferably constructed of foam plastic and is downwardly seated within the outer receptacle 16 in a manner which may best be seen from FIG. 3 of the drawings. However, and with attention now invited more specifically to FIGS. 2 and 5 of the drawings, as a result of the upper marginal portions of the inner receptacle 22 being inwardly deflected as at 28, corresponding lower portions 32 of the wall portions 24 are also inwardly deflected, but not to the extent of the upper marginal portions. Accordingly, vertically extending recesses or passages 34 are spaced about the inner receptacle 22 within the outer receptacle 16 and the lower ends of the passages 34 open downwardly into the space between the bottom walls 20 and 26 and the upper ends of the passages 34 open upwardly. Further, circumferentially spaced wall portions 36 of the inner receptacle 22 are disposed in tight surface-to-surface wedging contact with corresponding portions 38 of the wall portions 18. The portions 36 and 38 have registered small and large cross-sectional openings 40 and 42, respectively, formed therein and lower portions 44 of the wall portions 24 of the receptacle 22 have openings 46 formed therein opening into the lower ends of the passages 34. Further, the wall portions 18 have upper openings 48 formed therein registered with the recesses 30.
The upper end of the outer receptacle 16 is closed by means of a removable top wall 50 and the outer periphery of the top wall 50 includes an upwardly projecting and circumferentially extending inverted U-shaped curb 52 which is snugly telescoped down over the upper marginal portions of the wall portions 18 in order to frictionally retain the cover or top wall 50 on the receptacle 16. Further, the top wall 50 includes drain openings 54 formed therethrough spaced peripherally about the top wall 50 and registered with the recesses 30 in the upper ends of the passages 34. Also, the top wall 50 includes a central opening 56 downwardly through which the stalk portions 58 of artificial flowers 60 may be inserted.
In operation, a quantity of water-soluble fertilizer 62 is placed within the inner receptacle 22 and the latter is then wedged downwardly into the outer receptacle 16 with the openings 40 registered with the openings 42. Thereafter, the top wall or cover 50 may be secured over the upper end of the receptacle 16 and the stalks 58 of the artificial flowers 60 may be forced downwardly through the central opening 56 and into the fertilizer 62.
Then, each time it rains a portion of the rain water falling on the feeder 14 will be trapped within the confines of the curb 52 of the top wall 50 and will drain downwardly into the upper ends of the passages 34 through the openings 54. This water will flow downwardly through the passages and into the space between the bottom walls 20 and 26. As the quantity of water within the outer receptacle 16 increases it will flow into the bottom portion of the inner receptacle 22 through the openings 46 in order to dissolve some of the fertilizer 62 within the receptacle 22. Then, as the water level within the inner receptacle 22 increases it will reach the level of the openings 40 and flow outwardly therethrough and also through the openings 42 whereupon the fertilizer enriched water will flow downwardly along the outer sides of the outer container or receptacle 16 and onto the ground to be absorbed into the latter for feeding the tree by leaching action.
The operation of the feeder 14 is therefore extremely simple and it may be readily appreciated that the receptacle 22 may have a replenishing supply of fertilizer 62 placed therein merely by removing the cover or top wall 50. Further, the feeder 14 has a pleasing appearance and no matter how hard it rains only a certain portion of the watter falling onto the top wall 50 will pass downwardly through the openings 54. Of course, the size of the openings 54 may be varied in accordance with the amount of rainfall expected.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and charges will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
