- IThis invention` relates to devices thatcan be placed in an orchard heater as a heating medium.

,Y Y One of the objects' ofthis invention is toA J provide a heating medium that iscomplete I in itself as to priming igniting and' heating fora certain desired or required length of time. l

VAnother object is to provide'distinct vfillers and reiillers that can be` placed in orchard heaters by unskilled help and assure. a heating in a certain desired and required mannel Another l*object is to provide positive indications by which the filler is placed posi'- tively in a correctmannerin to a heater to assure arproper ignition and a proper 'burnm f v (ther'objects will appear from the followingdescription and appended claims as well as from the accompanying drawing, in which- Fig. l is a vertical midsectional view of a typical orchard heater in which solid or the like fuel is burned,v having laliller indicated therein of a certain form. tol leave a desired space for draft purposes, the liller being broken away at points to show inside parts and being generally designed to operate according to this invention.

2 is a cross section on line 2 2 of liglig. 3 is a fragmentary side elevation of a filler of a slightly modified form, the broken away section illustrating that the inside structure of this modified form is of equal or substantially similar structure throughout the whole length of the filler instead of different grade as indicated in the illustration of Fig. l.

Orchard heaters are most generally ignited and heated either with liquid or comparatively solid fuel.

In either case as now most commonly practiced the heater is filled or prepared for the heating during day-time in order that during the night when the temperature is normally the lowest a mere ignition of the lprepared v fuel in the heater remains necessary to pro- 50 duce the required heat fo-r the orchard. y

However, conditions are liable to make it impossible to.` so prepare Vay heater during day-time, or .weather conditions may necessitate an extended heating-during exceptionally severe andv long periods, f'

1 To insure against all eventual1ties,this i11-A vention features ameans that'facilitates-instant ignition and heating of an orchardfheater regardless of weather conditions or other possibilities. v if Y f i Considering the requirements for a heater of the typ-e illustrated in F ig. l in the drawing, in which the grate Zlis provided to support comparatively solid fuels such as wood,

coal, paper, asphalt, coke, and burnable rub- 65 bish and in which certain draft holes', 6 and 'l' are provided in order that thel fuel can be caused to'burn m a certain manner;v av certain filler 8 is roughly outlined in this connection with its'outer 'contours 9 spaced from 70 the inside walls of the heater l0, so that a draft of cool air cancirculate around the v filler S to escape` through the topmost holes 7, the other holes5 and@ being preferably placed so as'to face the incoming draft of 75 Any filler or 'burning or heating medium for such a heater is preferably of such a nature to assure a heating for a certain period, and on 'the other handto facilitate a 8 proper ignition under all conditions.

Such a filler consists preferably of fa burnable casing 11 of paper, cloth, or burnable composition for one thing and burnable material in the inside of the casing 1l.

The inner burnable material is for one purpose in the large portion of coarser and slower burning grade and in its smaller portion of finer and easier igniting grade, while for another purpose it is throughout of the same ycoarse grade. The mixed grade is used most commonly, in Fig. l, the ner grade being yindicated at the top at l2 and the coarser p may be desirable over a comparatively longv1 period as in case of a light frost during all of a night. In the rst case, the primer should preferably be placed at the bottom to assure an immediate burning of the whole matter of the iller; while in the second case, the primer should be placed at the top sothat the material will merely smolder slowly froml` the top on downwardly.

To assure a proper placing of the liller into the heater the filler is provided with indicating means, as in form of a solid bar or arrow pointing in the direction in which the filler normally should be placed, as indicated on the side of the filler at 14, at the top end at 15, another indicating means being shown as near the'primer. Either Vof these indicating means or similar suitable means can of coursebe provided, the means as illustrated merely being used to explain the principleof this feature, such indicating means however are preferably of a form to be easily graspable even inthe dark in order to avoid a misplacing. v y l In case of eXtreme cold weather conditions lasting over an unexpected long period of time, in which case a refilling of the heater should become rnecessary without interruption, a special refiller is provided as illustrated in Fig. 3, having the same coarse and slow burning but strong heat producing medium 13 throughout its length from one end 1.6 to the opposite end 17. This -type of a liller should preferably have equal indicating marks on both ends' as indicated at 18, by which such a reliller may be recognized. A suspending member, as in form of a hook 19 is provided on all fillers and relillers, by which this device may be suspended from the branch of a tree instead of being placed on the eventually damp ground.

' It must be understood that a filler of this type can be used on any grate, or in a stove i lilling placed near thevtop of said filling in Vsaid casing, whereby when the kindler is ignited at the top of said package the fuel is caused to progressively'burn downwardly in said heater covering an extended heating periodV and said package of fuel being spaced inwardly from said casing. whereby an ,upward draft of air is created between the-inner wall of said casing and the Vside of said package to assist combustion of fuel in said package. 2. In combination, a heater having a draft opening in its side wall and a package offuel placed in said heater and yextending above said draft opening, said packagelcomprising, a burnable casing having av filling ofinflammable material and a kindler offlmore readily inflammable material than the filling placed near one end of said package in said casing7 whereby when theV kindler is ignited the fuel is caused to progressively rburn in said casing covering an extended period', and said package of fuel being spaced inwardly from said casing whereby lan upwarddraft of airis created inwardly through ysaid passage and upwardly between the inner'w'all of said casing and the wall of said package to assist combustion of fuel in the'package. In testimony that I claim the. foregoing as my invention I have si edmy name. y
