3 SHEETS-SHEET 2- Zd/IZHEEFEi: I 7' w I, Even/n yfl qkiwm which may be conveniently formed by straps of metal bent to appropriate shape and secured to the bottom and the outer wall, as by rivets 15.

The second part of the stove consists generally of the annular cover 16 having the outer comminglin tube, the protecting hood, the outer wick tube, the wick, and the wick raiser mechanism. The cover 16 is "provided with a depending flange 17 forming a skirt overhanging the. upper wired edge of the reservoir there-beneath.

Between its inner and outer peripheral portions the cover is shown as provided with a plurality of angular straps 18 the bottoms of'which. may be secured to the cover in any approved manner, the upwardly projecting portions 1.9 of the straps having secured thereto a frustoconical hood 20, which extends above the tops of the commingling .tubes. The base of the hood 20 is substantially flush with the surface of the portion of the cover therewithin, such portion of the cover being preferably projected upwardly into a ring or corrugation, as shown i at 21. The inner edge of the cover is projected downwardly, as shown at 22, and the extreme bottom portion 23 is secured to the outer wick tube 24. This wick tube projects so a considerable distance above the inner wick tube and is shown as provided at its top with a series of inwardly projecting fingers 25 constituting a stop for the upper edge of the wick. A slight space is provided between the downwardly projecting portion 22 of the cover and the portion of the outer wick tube adjacent thereto which s ace is adapted to receive the outer commingling tube 26, which may be secured to the parts by peening the overlapping metal parts,

in the manner employed for securing together the inner commingling tube and the wall 6.

27 denotes a wick, which is inserted in the wic space provided between the tubes 3 and 24.. This wick is preferably of considerably lessthickness than the width of the space between said tubes, and the inner surface of the wick is engaged by a carrier consistin of a cylindrical band28 having 'a plura 'ty of outwardly and upwardly projecting spring fingers'29 which are adapted to engage the inner surface of the 'wick- The upper end of the wick can be raised until 5 gers 2 5. The bottom of the band or skirt 28 is flared outwardly, as shown at 28, and the bottom of the outer wick tube is correspondingly flared, as shown at 24. It is preferred to flare the bottom of the wick, and this flaring may be secured by slitting the bottom of the wick, as indicated at 27 (see Fig. 3).

The band 28' may be conveniently raised as! and lowered by a pair of diametrically opit is brought into engagement with the finposed straps 30, said straps having their inner ends connected to the flaring skirt 28 and extending outwardly therefrom a suflici'ent distance to clear the bottom of the wick, whence they are projected. upwardly and have secured to their upper ends a pair of straps 31. These straps project through the cover 16 and are shown as connected to a band 82 which encompasses the burnerand boom. About 90 from the point of connection with the straps 31, an extension of the band is pivoted between a pair of lugs 33 secured to and projecting upwardly from the cover, and at a point diametrically opposite such pivot the band is provided with an operating handle 34, which may be conveniently formed from the metal of the band itself.

When it is desired to extinguish the flame, the frustoconical cover 35 may be applied to the stove, the cover being somewhat greater in diameter and height than the hood 2(), whereby it may be dropped over said hood, within the band 32, and serve to extinguish the flame, also to protect the 9 burner parts therebeneath. The hood will be provided with a handle 36, for convenience of manipulation;

It will be noted that, in the embodiment of my invention hereto-fore described, the reservoir, the inner wick tube, and the inner commingling tube with its cooperating air controlling caps and'diaphragms constitute one assembly and that the removable cover 16, outer wick tube 24:, outer comrningling tube 26, wick 27, and the wick raising parts, together with the hood 20, constitute another assembly. The third element which, strictly speaking, is not essential to the op eration of the burner, is the hood 35, which serves to extinguish the flame and to protect the parts therebeneath from rain when the heater is not in use.

From the foregoing description it will be apparent that I have produced a stove or heater which is extremely convenient of operation while correspondingly simple of construction and economical of production.-

The stove consists essentially of but three parts, including the cover or extinguisher 1 35. When it is desired to fill the reservoir, it is necessary only to tilt or lift thecover,

as shown in Fig. 3, whereupon the reservoir may be 'filled from a pail, without the necessity-fof a funnel or any special filling appli- 20 ance and without the-necessity ofobserving any particularcare, thus.fa.cilitating the operation of filling the reservoir. In the case of orchard heaters, where a large number of heaters are in operation at the same 25' time, the time thus saved is a very considerablesaving item. Furthermore, the parts are extremelieasily assembled and disassembled. Should the commingling or burner tubes require cleaning, this operation can be I performed very readily and easily by merely removing the cover from the reservoir. This exposes the-outer surface of the inner tube 9 and the surface of the outer tube 26, and these surfaces may be quickly cleaned by means of a brush or any other convenient article.

5 there is. shown a modification of the invention illustrated in the preceding views, wherein the open topreservoir is provided with a perforated skirt 37 in place of the strap metal legs shown in the other views and wherein the commingling tubes 3Sfa'nd" 39 are not secured to the tops of the I. inner, and outer wick t-ubes, respectively, and

do not form part of the reservoir and the cover assembly respectively. The inner tube is located: above the top of the inner wick tube The outer tube is seated within an anl 'i'llar space 4Q fsurriounding. the upper end of; the'outer wick tube 24. r The commingli ngl, tubes are connected by tie rods d1 ex- "t end'ihg th'ereacross, and the oommingling tube assembly may be conveniently centered witlri respect; to the tops of the wick tubes 49,24? and the wick therebetween by meansofifthe vertical wall 42 defining: the

-iwick 27 is provided" with a. band"28, with the spring fingers 29, as; described; hereinbeforefandi the, wick may be raised" and lowered byfhand, the operator; grasping the flaring bottom oflthe bandfor-this purpose when the cover is removed from the reservoir.

It will be observed-that; in the modification j ust described, no vd iap hrngl s are. rovidedbetweenthc, bottom and'the top 0 the .inner commingling tube, the bottom of said tube being forinedbythe cap 43Whi0ll is secured to the top ofthe inner wick tube and which is shown as provided with a series of perforations 4:41.

The stove or heater shown herein. has been found to be extremely ciiicient in operation, not only in the matter of thoroughly heating the surrounding atmosphere, but in the matter of immunity from smoke and from extinguishment and serious interference by drafts. herein, it is possible to heat an orchard efliciently, without damaging the fruit or with out the necessity for Washing the fruit in order to remove therefrom the carbon stains which will be deposited thereon by a smoky flame. While the possession of these advantages necessarily makes the heater peculiarly efficient as an orchard heater, 1 Wish to be understood as not limiting my invention to this one use, since, because of its ciency and freedom fromsmoke, it is applicable to the heating of water, the heat ing of garages and other inclosed s aces, and is generally useful wherever eflicient heating is desired.

While I have described my invention in detail in connection with the modifications illustrated herein, it is to be understood that I- do not thereby limit my invention to such detailsof construction and that these details may be varied, or departed from, more or less, without avoiding the spirit of myinvention.

With a heater such as disclosed.
