Specification of Letters Patent. I

Patented Oct. 12,1915.

Application filed February 2, 1915. Serial No. 5,784.

To all whom it may concern:

Be it known that I, JOSHUA H. GRIFFITH, a citizen of the United States of America, residing at Ellis, in the county of Ellis and State of Kansas, have invented certain new and useful Improvements in Gas-Generating Burners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to gas generating burners and has for its principal object the production of a burner which may be placed within the fire box of a stove in such a manner as to allow the burner to easily heat the desired portions of the stove when the same is in operation.

Another object of this invention is the production of a gas generating burner which is so formed as to easily vaporize the oil so that upon the mixing of the vaporized oil with the air, a gas will be produced which is adapted to be ignited upon passing from the interior of the burner.

Another object of this invention is the production of a gas generating burner having a simple and efficient means for regula'tingthe amount of vaporized oil which is adapted to be admitted to the mixing cham ber whereby the amount of gas produced may be increased or diminished as desired.

A still further object of this invention is the production of a gas generating burner having a plurality of burner pipes extending from its gas chamber whereby the burner pipes may extend to desired positions within a stove so that the various portions of the stove may be heated as desired.

WVith these and other objects in vi'ew,'this invention consists of certain novel combinations, constructions, and'arrangements of parts as willbe hereinafter fully, described and claimed.

In the accompanying drawings :Figure 1 is a detailed perspective view of the gas generating burner. Fig. 2 is a central longitudinal section through the burner. Fig. 3 is a top plan view of the device. Fig. 4 is a horizontal longitudinal section through the device, taken below the central partition.

Fig. 5 is an end elevationof the burner.

Fig. 6 is a section taken on the line 6-6 of Fig. 2. Fig. 7 is a section taken on the line 77 of Fig. 2. Fig. 8 is a fragmentary sectional view of a portion of the device illustrating the manner in which the valve member is carried. Fig. 9 is a'detailed perspective view of the valve stem. Fig. 10 is a fragmentary detailed perspective view of the upperportion of the burner, showing the gas pipes extending therefrom.

Referring to the accompanying drawings by numerals it will be seen that -1 indicates the body of the burner which is preferably cylindrical in shape but which may be so constructed as to embody any desired shape or formation. This body 1 comprises a casing which is hollow and has one end thereof closed by the head 2 andthe opposite end thereof closed by the head 3. The head 3 is provided with a plurality of openings 4 thereby forming the stays 4. It will be seen that by providing the openings 4, air maybe admitted into the interior of the casing 1 as the occasion requires. A partition 5 is fixedly secured within the interior of the casing 1 adjacent its central portion so as to extend in a horizontal plane as will be seen by referring to Fig. 2. This partition 5 has an integral wall 6 formed upon one end thereof, which wall 6 extends at right angles to the partition 5 so as to be connected to theinncr upper portions of the casing 1 thereby forming a tight closure at one end of the partition 5. The opposite end of' this partition 5 however terminates at'aspaceddistance from the end 2 as indicated at 3 in Fig. 2 for the purpose of allowing the gas formed in the mixing chamber to pass around this end of the partition. A number of apertures 7 are formed in the casing 1 for the purpose of allowing the gas carried within the gaschamber 8 to escape from the interior of the burner and to be easily ignited as the samepas'ses through the apertures 7. A pipe 9 is carried upon the upper portions of the casing 1 so as to extend around the apertures 7 as clearly shown in Figs. 1 and '3. This pipe 9 is fixedly retained in position upon the casing by means of the clips 10 which embrace the pipes and are fixedly secured upon'theupper portions of the casing in any suitable manner It will. be seen that as the oil passes through the pipe 9 the heat from the flames caused by the burning of the gas passing through the apertures 7' will heatthe pipes and cause the oil to be vaporized before it reaches the mixing chamber. This pipe'9 is provided with an elongated depending neck 13 which communicates with the valve casing 14 by means of the neck 14. vThis neck 13 extends upwardly to communicate with the valve casing 1 1 within the air chamber 11. The valve-casing 14: extends entirely through the air chamber 11 and co1nmunicates with the interior of the mixing chamber 12. In order to retain this valve casing in its correct position one end thereof is carried by the thickened portion of the head 3 while the central standard 15 is adapted to be positioned upon the valve casing for the purpose of supporting the inner end thereof. This standard 16 extends in a vertical position so as to bear against the vertical wall 6 or the partition 5. The valve member 21 is provided with a gripping portion 22 which may be easily gripped so as to actuate the valve member 21 as the occasion requires. a; threaded portion 23 is formed. upon the valve member 21 and this threaded portion 23 is adapted to pass through the threaded opening 21 formed in the thickened. portion 15 of the head 3; It will be seen that the valve member 21 extends tliroughout the entire length of the casing 143 so as to pass from the inner portions of thecasing as clearly shown in Fig. 2. Since the casing 1i tapers toward its inner end the inner end of the valve member 21 will become wedged as shown at 21 in Fig. 2 for the purpose of cutting off the supply of? vaporized oil when it is so de sired.

When the device is in operation air will pass through the openings 1 formed in the iead 3 and into the air chamber 11. The air may then pass downwardly into the miX- ing chamber 12 under the partition 5. The gripping portion 22 may then be actuated so asto'movethe valve member 21 and allow oil to pass into the mixing chamber 12. As the oil and air mix. a. gas will be formed which will pass around the end of the partition 5 and will pass into the gas chamber 8; As the gas passes from the chamber 8 through the a ertures? it may ignite so asto' allow the flames to heat any desiredarticle or receptacle or to heat a stovewithin which the burner is positioned. As the flames heat the pipe 9 the oil therein will be vaporized so that upon passing through the neck 13 into the casinghl it may bedischarged in a vaporized condition from the casing 14: into the mixing chamber thereby reducingthe cost of producing the gas and causing the burner to operate more efficiently. It will of course be seen that the draftof the air caused by the passage of the air into the chamber 11 through the openings 4" will cause the gas formed in the mixing chamber to quickly pass into the gas chamber 8" thereby preventing a backfire in the mixing chamber 12.

Itwill beseen thatthe'casing 1 isadapted to carry'a' nipple 25 communicatingwith. the interior of the gas chamber 8'. The gas pipe 26 maybe held in engagement with. the

nipple 25 by means of the collar 27. From this pipe 26, burner pipes 28 may extend and the admission of gas to these pipes 28 may be regulated by the valves 29. It will be seen that the gas from the chamber 8 will I pass through the nipple 25 and into the pipe 26; As the various valves 29 are actuated the gas will pass into the diiferent burner pipes 28 and will be discharged through the burner openings 30. These openings may be provided with a blaze deflector 31 supportedupon the frame 32 soias to cause the blaze-'inade by the igniting of the gas passing from the burner openings to be spread or deflected. It is obvious that the pipes 26 and 28 may extend in any desired shape or to any desired position so as to efficiently heat the several portions of a stove Within which the burner is adapted to be positioned.

From the foregoing description it will be seen that a very efficient gas generating burner has been produced which is so formed as to be easily carried within a stove for heating the stove and which has its several parts so arranged as to readilyvaporize the oil before" the oil is passed to the mixing chamber whereby a very pure gas may be very quickly'and cheaply producedwhen the burner is in operation. It will also be seen that the valve operating mechanism is so formed as to easily control the supply of vaporized oil to themixing chamber, thisvalveoperating 'mechanismbeing easily supporglzed in a convenient'po'sition to be operate It will be seen that" the casing 14': extends for a" considerable distanceinto the mixing chamber and'owing'tothe fact that the cool-' ing chamber is' formed adjacent one end of this mixing chamber, the point Within the mixing chamber whereat the vaporized oil is admitted is far-enough from the open end of the generating-burner to prevent the igniting of the vaporized oil by the flames without the burner. Therefore, it will be seen thatthe clogging ofthe'mixingchamber by the formation: of the-soot therein is prevented and consequently theburner will be clean within itsinner portions at all times so as to allow the gas to' be easily generated.

What I claim is 1. In a gas generatingburner of the class described, the combination of a casing, a central partition carried within said casing, forminga'mi'xing chamber and agas chamber, said partition provided with an integral vertical wall extending at right angles thereto forming an air chamber, said partie tion terminating ata spaced distancesfrom one end of'said casing to communicate said mixing and gas chambers, and' means for. supplying said mixing: chamber with vapors ized' oil, said" air chamber; having openings to the outside air and communicating with saidinixing chamber whereby air'issupplied;
