Jan. 10, 1956 A. HALLUM SOIL WARMING DEVICE Filed Oct. 28, 1953 v/ INVENT'OR. flzrd/ezz/ #4212077 ATTCJ RN EYS United States Patent O SOIL WARMING DEVICE Andrew Hallum, Springfield, Mu. Application October 28, 1953, Serial No. 388,857

4 Claims. (Cl. 47-49) This invention relates to a heater, and more particularly to a device for supplying heat to a hill of soil or the like in which seeds are placed.

This application is a continuation-in-part application of my co-pending application, Serial No. 260,022, filed December 5, 1951, now Patent No. 2,723,495, for a Soil Warming Device.

The object of the invention is to provide a heater for expediting the growth of watermelons and the like which are subject to the damaging eifects of frost or cold weather, the present invention providing a warming device especially suitable during the incubation period of the seeds.

Another object of the invention is to provide a heating apparatus wherein the fuel tank is placed above the ground, there being a shield positioned around the wick tube or burner.

A further object of the invention is to provide a heating apparatus which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to desig nate like parts throughout the same:

Figure l is a longitudinal sectional view taken through the burner and showing the fuel tank and wick tube in elevation, the fuel tank being positioned above the ground, and there being a Ushaped shield positioned around the wick tube or burner.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a plan view showing the shield to be positioned around the burner.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1.

Figure 5 is an enlarged view similar to Figure 4, showing a cap on the upper open end of the shield.

Figure 6 is a plan view of the cap shown in Figures 4 and 5.

Figure 7 is a plan view illustrating a modified cap wherein there is provided openings instead of slots.

Figure 8 is a plan view showing a further modification of the invention.

Referring in detail to the drawings, there is shown a fuel tank which is indicated by the numeral 70, and the fuel tank 70 is provided with a cover 71, the fuel tank 70 being positioned on the ground. A wick tube 72 extends from one side of the tank, and the wick tube includes a horizontally disposed straight portion and a vertical portion, there being a U-shaped shield 73 which is positioned around a portion of the wick tube 72. Thus, with the tube and shield positioned in a hill 74, heat will be supplied to soil in the hill as the wick 75 which extends from the tube 72 burns. The wick 75 is positioned adjacent the upper end of the compartment 88.

The shield 73 is provided with a closure plate 76 through which the tube 72 extends, and a cover 77 is provided on the upper end thereof.

2,729,915 Patented Jan. 10, 1956 The shield 73 is also provided with a partition 78 and a cap 79 having a flange 80 on its end is positioned on the end of the shield. The flange 80 be provided with slots 81 which provide means for the escape of gases of combustion as well as for the inlet of air to support combustion, or as illustrated in Figure 7, a flange 82 similar to the flange 80 may be provided with spaced openings 83.

From the foregoing, it is apparent that with the shield 73 surrounding a portion of the wick tube 72 and with the end of the wick tube positioned in a hill 74, heat will be supplied to the surrounding area of the hill to seeds therein as the wick 75 burns, the seeds being indicated by the numeral 84.

The cover 71 of the tank may be provided with spaced openings 85 which provide vents as shown in Figure 2. The shield 73 may also be provided with a base 86 whereby a complete enclosure is provided laround the section of the wick tube positioned in the ill.

Thus, by supplying fuel or oil to the burner from the tank 70, the burners will burn continuously to thereby supply heat to the soil which has seeds therein so that during the incubation period of the seeds, there will be no danger to the seeds from frost or cold weather. Air for supporting combustion of the wick flame can enter through the openings in the flange 80. Thus, air for sup porting combustion can enter through the slots 81 in the flange 80. Furthermore, the wick is very near the flange or cap so that the wick will burn. The compartment 88 is not really a combustion chamber but merely provides a space through which extends the upwardly projecting tube 72.

Referring to Figure 8 there is shown a still further modification of the present invention. Thus, in Figure 8 the wick tube 72 is surrounded by a shield 86' which may be secured to a portion of the wick tube in any suitable manner, as for example by welding at 87. The shield 86 is used in lieu of the previously described partition 78 and the shield 86 provides sufficient room so that air can get to the wick.
