' 615 L KELAND, FLORIDA VEGETABLE AND ORCHARD HEATER My present invention contemplates the provision of a cha "coal burn ig heater for her. ing orchards and use in pro l y to vegetables, the said heater beiu .cted on the principle that the fuel ignitedat the top of the fuel in the heater, and as the combustion goes down principally around the edge of the fuel the coinbr ion in a com paratively short time will re. 2 rate, a n d the combustion will contii r7 "111d point until the charge of fuel consumed. floward the end of the operation the lov twelve inches, approximately, of the heat becomes red hot and above that point very little heat is generated so that during the latt r consumption of the charge the upper par of the heater turns black and cornbu hove the apex of the grate prac ically This action is due to the fact that immer Uely after the char e is initially ignited carbon dioxide is generated, and as it is pram" impossible for combustion to take pie ide the relative a and air remain an V erated. The volume of our son dioxide becomes greater as on. on continues down tl1C-l1921.t61,llill uni l is upplied by the apertures in the co i .r ate so coinbus ion can continue and the 0. charge be consumed. Incident to the oper on of the heater the temperature is greater two feet out from the heater 1 t the bottom than it is directly over the top of the heater.
With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of cons ruction, l in the combination and arrangement of i .i as will be hereinafter more fully described and claimed.
In the drawings Figure 1 is a perspective of the heater embodying the features of the invention.
Figure 2 is a vertical sectional view there through.
Figure 3 is a transverse horizontal section taken substantially on the line 33 of Figure 2,
Figure l is a similar view showing the grate removed, and
Figure 5 is a perspective of the grate which 1929. Serial no. 411,309.
forms an important part of the invention.
Referringto the drawings in detail, it will be seen that the numeral 5 denotes a cylindrical body disposed vertically and supported by legs 6 depending from the lower end there of. The lower portion. of the body 5 is swaged inwardly at 7 and 8 respectively for forming shoulders and the portion between these shoulders is provided with openingsl) which form breathers for oxygen.
A strengthening swaged formed shoulder 10 is provided adjacent the top of the body 5.
A. lid 11 is formed with aflange 12 to telescope outside the upper end of the body.
Apertures 12a, are provided in the upper portion of the body 5, and the said flange 12 is apertured at 12?). lvlanifestly by turning the lid 11 about its axis the oxygen for supporting combustion can be nicely controlled.
At 14 is the cone-shaped grate which offers a baflie to draft and afford a support for charcoal. In the preferred embodiment of my invention the said grate 14 is provided with a plurality of annular series of openings 15 the diameter of the openings in the series being graduated to become smaller as the openings approach the apex of the cone.
In the operation of the heater the fuel is i 'nited at the top of the heater and the fuel is consumed in the manner hereinbefore explicitly set forth. Incident to the operation and as demonstrated by experience the temperature is greater at substantially two feet outwardly from the heater at the bottom than it is directly over the top of the heater, this being due to the construction of the grate as described. From this it follows that the heater will afford a low heat calculated to protect vegetables adjacent to the heater; also, that the heater will dry ground surrounding the heater for a considerable distance which makes the heater peculiarly advantageous where winter vegetables are raised.
It is thought that the construction, utility and advantages of this invention will now be quite apparent without any more detail description thereof. It will be seen that by burning charcoal on the grate, said grate will tend to maintain itself clean because of the arrangement of the openings 15 and the notches 16, said notchesallowing the sifting out of burnt charcoal.
The structure may be manufactured at a low cost, and made light and durable so as to be thoroughly efficient and reliable in use in orchards and other desired places.
The present embodiment of the invention has been disclosed in considerable detail merely for the purpose of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of invention and the description. g
It will be apparent that changes in the details of construction, and in the combina tion and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is The herein described heater for burning charcoal, comprising a hollow upright body, and a grate therein supported only at its lower edge and extending throughout the transverse area of the hollow uprightbody, said body adapted at its upper portion for the passage of gases and open at its portion, below the grate, for the passage of air; said grate being in the form of a thin wall which interiorly and exteriorly describes an upwardly extending cone, and being provided in its edge with spaced, comparatively large openings which extend inwardly from said edge, and being also provided throughout the remainder of its area with outer apertures smaller than said edge openings and inner apertures smaller than said outer apertures.
