\ cation,

This invention has relation to a ty e of "3,10 burner for utilizing liquid fuel, suct vas `1:\ gaslene, naphtha, coal oil, etc., and which may be employed either in a cook stove or in heating stove, according as the burner is to be arranged in a horizontal or in a vertical position, the construction of the burner eing substantially. vhe same in both forms,

the only di'erence bein(r in the arrangement of the flame outlets, w uch in the burner for cook stoves extend lengthwise and in the burner des'gned for heating stoves run crosswise of the burner. For a full *understanding of the invention and the merits thereof and also to acquire a knowledge of the details of\construction and the means for effecting the'result, reference is to be had to the following description and accom anying drawings.

"hi e the invention may be adapt-ed to different forms and conditions by changes in the structure and minor details without departing from the spirit or-essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in,

which: y

Figure 1 is a perspective view of a burner designed for cook stoves embodying the invention. Fig. 2 is a vertical central longitudinal section. Fig. 3 isa view similar to Fig 2 of a modification, showing the burner 4c adapted for heating stoves and' designed to be arranged vertically. Fig. 4 yis a detail perspective view of an end portion of a wick, showing the meta-l protectors fitted to the tip thereof, the band protector being moved back from the tip. y

Corresponding .and like parts are referred to in the followinv description and indicated in all the views of the drawings by the sam reference characters. The burner embodies in its construction, a )ipe 1 for containing a quantity of liquid iuel, and said pi e may be connected with a font, tank or t 1e like for supplying the liquid fuel continuously, thereby obviating the necessity for charging the burner at intervals. The pipe 1 vis providedin its sidesl .Specification of Letters Patent.

passes to supply that consumed when the urner is in operation. f' A cylinder 3 is fitted upon the pipe 1 and is spaced therefrom, said space being closed at its ends and adapted to or granular nature. The pipe 1 is likewise filled with an absorbent, such as mineral wool or cotton waste. The cylinder 3 is provided with openines 4 in its sides, said openings being covered by wire gauze 5 to prevent the passage therethrough of the granular material em loyed for filling the spaces. A double walle cylinder 6 encircles the cylinder 3 and is spaced therefrom, the ends sand or granular material filled therein. The space between the inner and outer walls comprising the double walled'cylinder 6 is closed at its ends and is filled with either asbestos or fire clay or any other refractory sides of the double walled cylinder 6 and extend through both shellsthereof and receive and are fitted with wicks 9, the inner ends of said wicks entering the space formed between the cylinders 3 and 6 and having the granular filling material 10 surroundino the same. The openings 7 extend lengthwise of the burner, as indicated in Figs. 1 and 2, and crosswise of the burner, as shown in Fig. 3,

' reservoir so as to receive a constant supply of liquid fuel therefrom. For .catching any overflow, a dri pan 1l is fitted to the burner and is supplier with a bail 12, whereby the pot or a cook stove or removed therefrom when desired.

Y In the modification shown in Fig. 3, the oil pipe 1 has its upper portion ierforated, only, to insure supply of oil to t e topmost ward to the lower flame outlets. The tubes be filled with any material either of a fibrous tubes S which constitute the flame outlets whereby the latter may be arranged in ver-.l

burner may be placed in position in the fire with perfor-ations throughwvhichA theoil of the space being closed so as to retain the 1 material. Openings 7 are formed in the A i flame outlets, sufficient oil passingV down- 8 are preferably inclined upwardly towards their outer ends at an angle of about fortyfive degrees,` thereby preventing waste of oil and insuring proper supply to lthe wicks Each of the wicks is provided with a tip 13 and a .band 14, each constructed of foraniinous'orreticulated material. The parts 13 and 14 constitute protectors to prevent a too rapid burning away of the wicks and also to equalize the heat by distributing the same by conduction and convection.

Having thus described the invention, what is claimed as new is:- A

l. In apburner for consuming liquid fuel, the combination 'of a. perforated pi e, a double Walled cylinder fitted upon sai pipe and spaced therefrom' and having said space l supplied with filling material and closed at opposite ends, said cylinder having corresponding openings in both walls, tubes fitted inthe openings of the walls of the said cvlinder, and wicks fitted in said tubes and having -their inner ends extendedy into the space between the double walled cylinder and perforated pipe embedded in the filling material.

2. In a burner of the character specified, the combination of a perforated pipe, a cylinder fitted upon said pipe and s aced therefrom and having the space close at its ends,

said cylinder having perforations in its sides,

"Q, soecesl wire gauze fitted upon the cylinder and closing and protecting the openings thereof, and a secon( cylinder lets fitted u on t e perforated pipe and spaced from t e first-mentioned cylinder and having the ends of said space closed, the s ace between the two c rlinders being supp icd with filling materia 3. The herein described b'urner coniprisino a perforated pipe, a erforated cylinder fitted upon said pipe an( spaced therefrom and having the space closed at its ends, wire I gauze fitted to said cylinder and extended over the perforations thereof, a double walled cylinder fitted upon the perforated pi e and spaced from the rst-1nentioned cylin er and rovided with fiame outhaving the space closed at its ends and sllpplied with granular lling material, tubes ted in the openings of the walls 0x'- shells com.- prising the double walled cylinder, and wicks tted in said tubes and having their inner ends extended into the space formed between tlhe first-mentioned and double Walled cylint ers.

In testimony whereof I affix my signature in presence of two witnesses.
