This invention relates to new and useful improvements in gas burners.
The principal object of the invention is to provide a burner having means for preheating the air which is admixed with the whereby a more combustible mixture is 1 produced.
Another important object of the invention is to provide means for introducing an auxiliary supply of air to the preheated gas mixture at the point of combustion. whereby a more intense flame is produced and the consumption of gas is reduced as well as fumes substantially eliminated.
Another object of the invention is to provide a preheated chamber in which the air is caused to travel a considerable distance before being mixed with the gas, thus giving it an opportunity to become thoroughly preheated.
A further object of the invention is to constructed the burner in a number of parts which may, in some forms be readily cast without the use of cores and which parts may be easily assembled and secured together in a simple manner.
A still further object of the invention is to provide burner units of a simple nature arranged to be readily removed from the burner structure and designed to co-operate in the auxiliary introducing of air.
A construction designed to carry out the invention will behereinafter described, together with other features of the invention. The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and whereini Fig. 1 is a plan view of the burner assembly constructed in accordance with my invent-ion,

Fig. 18 is a transverse/vertical sectional view taken on the line 18-18 of Fig. 14,
Fig. 19 is a plan view of the mixing chamher, and
Fig. 20 is an enlarged detail of one of the air introducing bosses and burner units.
In the drawings the numeral 10 designates the lower or bottom section of an elongated manifold. The said lower section has an air inlet opening 11 in one end of its bottom 12, which latter inclines upwardly toward the opposite end and in this latter end is provided a port 13 which may be connected with a suitable gas supply pipe (not shown).
The lower section 10 forms the major portion of the manifold in this particular form of the invention and constitutes a preheat ing chamber. 1
The lower section has a countersunk rectangular shoulder 14 in its upper portion and is also provided with an outwardly directed flange 15 on its top. A flue member comprising a rectangular plate lti and a flue 17 is seated on the shoulder 14. The flue extends longitudinally of the lower section or chamber 10 and inclines downwardly toward the port 13, its lower end being open and its upper end closed. By observing Figs. 6 and 7, it will be seen that a passe provided along each sideand under 11%:
A distributor or plate 18 restsupon theplate lfiand is provided with anupstanding distributing head 19 di over the upper closed end of the flue 17. A eoncaved boss inclining downwardly from the head depends on the under side of the plate 18 so as to hang in the top of the flue 1T. \Vhen the burner assembly is in operation, gas \Vlll be supplied through the port 13 and being under pressure Will be directed into'the flue 17. Air will be drawn in through the opening 11 and caused to travelalong the passages along each side and under the flue 17. This air upon reaching the open end of the flue will be drawn thereinto and mixed with the gas. The heat from the burner will cause the walls of the flue, the boss 20, the plate 18 and the head 19 to become hot. Thus, the air will be preheated as it travels along the outside oi the flue and the mixture of air and gas will be heated while traveling thronglrsaid flue.
A top or upper section 91 fits over the head 19 and rests upon the plate 18 within the opening at the top or. the preheating charm ber 10. The head 19 is preferably made fiat so that the top section will lit thereover and the flange 15 surrounds the top section,
thus holding it against lateral displacement. The head 19 is provided with. a plurality of ports 22, 23 and 24 respectively. These ports are given such diameters as to rutoperly distribute the gaseous mixture, this being necessary because the head is located nearer one end of the top section 21. The ports 23, which are on. each side of the head, may be of the same diameter and the port 22 maybe of a like diameter or it may be of a dillerent diameter i't' TEOUIlCl advantageous. The port 2-1 is made considerably larger so as to provide a. generous supply of the mixture for that portion of the top section extending therefrom.
One of the important :lt'eatures of the in vention resides in burner units constructed to admit anauxiliary supply of air to the preheated gas'mixture, one 0t such, units being shown in detail in Fig. 20. The top section 21 is provided with a plurality of up-standing tubular bosses or burners 25 connected with the manifold through ports 26. These burners may be suitably arranged. Satisfactory results have been had with a double row of the same, as is shown in Fig. 1. Each burner has a plurality of vertical air inlets or louvcrs 27. 'In the lmver portion of each burner is provided an internal annular shoulder or seat 28 below the louvere, while another internal annular shoulder 29 is provided at the top above the louvcrs.
I11 each boss is disposed a mixing unit 30 and each unit comprises a top disk 31 resting on the shoulder .29 and a bottom disk ?2 resting on the shoulder 28. Spaced vertical tubes 33 extending through and fastened in these disks project above and below the same. between the tubes. Each mixing unit may The top dislefll has perforations bet be made to drop into the boss so that the dislc resting upon the shoulder 28 will close the port 26, while the top disk 31 resting on the shoulder 29 will close the top of the boss. It to be understood that the bosses will be comparatively small and the tubes even small if. The mixing units may be readily removed for cleaning and are easily placed in assembling the structure.
The gaseous mixture, which has been thoroughly preheated in flowing through the chamber 10 flue 17, and escaping through the ports of the head 19 into the top section 21 will be heated to a greater extent as it flows through the said top section ill. and escapes through the ports 26. This mixture will pass upward through the tubes 33. Auxiliary air will be drawn in through the louvers 27 and will pass upward through the perforations la-i, thus further admixing air and n'omoting economical comluuition in the flame which burning above the unit 30. This generous supply of air will greatly reduce the fuel consumption and not only assure a more perfect combustion but will tend to eliminate fumes.
In Figs. 8 to 13, I have shown another term in which the invention may be carried out. A bottom section eh) iimludcs a longitudinal preheating chamber ell havi g an air inlet opening 42 at one end. as is best shown in Figs. 9 and 10. The bottom chamber inclines upwardly and opens into a longitudinal flue 43 which inclines upwardly toward the air-rulmitting end oi the section. The chamber and the flue are substantially parallel, being separated by a partition wall ll, as is illustrated in the several figures. The chamber ll is quite similar to the chamber 10 previously described, while the line 4:3 is similar to the tlue 17. A port let provided at the front end of the lluc 43 tor receiving a gas supply pipe 4:5. Gas supplied undcr pressure is directed into the flue l3 and air drawn into the opening 1 is pulled along the chamber 41 and mixed with the gas in the line 13.
The lower section all] has a comparativcly flat top surface and is provided with a marginal scaling groove 46 which has a branch -lJT extending along the top of the wall ll. An intermediate member is has a Hat under surface and is prm'ided with :1. depending sealing bead ll) litting in the groove lo and provided with a branch 50 titling in the groove d7. The member all) is provided with cars 51, while the member l8 has registering." cars 52 so that bolts 53 passed through said cars will l'asten the parts together, the beads and grooves preventing the escape of products from between the members.
The member l8 has a. lucl discharge open-- ing 5-1. extending from the upper end ol' the flue 13 and preferably inclined to direct the gaseous mixture into an upper section as.
ltltl Lil The section 55 has a depending marginal head 56 fitting in a sealing groove 57 on top of the member 48. It will be noted that the member 48 has a concaved hood 58 overhanging and forming the upper portion of the fine 43. This hood inclines as does the flue so as to permita free escape of the gaseous mixture at the upper end of the fine. The air and the gaseous mixture are, of course, preheated in the chamber ill and the line ll-l in the same manner in the form previously described. The top member 55 is equipped with burner bosses and units the same as are shown in Fig. and further description of the same unnecessary.
In Figs. let to 19 still another form of the invention is set forth. In this form (it) designates the intermediate section and 61 the upper or top section of an elongated manifold. The lower section has a rectangular scaling groove (32 in a horizontal plane adapted to receive a rectangular bead (33 de pending from the lower edge of the section (51. A lower section or preheating chamlu-r (Sat has a horizontal marginal groove in its upper edge receiving a CUll1l')l9Illllttlt'y bead 66 depel'iding from the bottoinof the section 60. The chamber also has a pair of forwardly directed grooves 7 in the upper ed of battle walls 68 receiving beads 69 depending from the section 60.
It will be seen that the structure comprises three main elements, each of which may be easily cast without the use of cores. On each side at its front, the chamber Get is provided with cars 70 underlying cars 71 of a hood 72 formed integral with and projecting from the section 60 over said chamber. Bolts T25 passing through the said ears secure the chamber and the hood together. The chamber, near its rear, has ears Tl on each side receiving bolts 75 passing down through the sections of the manifold, as is shown in big. l'i' whereby the units of the assembly are fastened together. It will be seen that by the use of four bolts the entire structure may be securely fastened together ready for use.
The chamliier Get comprises compnratively deep forwardly directed air passages or channels 76 arranged on each side and each having an air admitting port 77 in it bottom at the rear end. These lines are disposeiil horizontally on each side of the battle walls (38 and between the battle walls is a rearwardiy directed mixing flue 78. By observing Fig. 18 it will be seen that the pas ages 76 incline upwardly and forwardly while the fine 78 inclines upwardly and rcarwardly.
As is best shown in Fig. 19, the baflie walls 68 terminate short of the front wall of the chamber and each air channel converges toward its forward end discharging into the front end of the mixing channel 78 through a reduced throat 79. The hood 72 has a central dome 80 arching over the mixing flue 7 8.
A lip 81 de ends from the front end of the dome and ts in aisump 82 in the front of the chamber. A gas cock 83 is screwed into an aperture 84 in the lip and is also fastened on the end of a. gas supply pipe 85. i
-It will be seen that gas discharged from the gas cock 83, ,whichmaybe of the usual construction, will be directed rearwardly and upwardlyin the channel 78 whereby air will be drawn into the passages 76. through the ports 77. the whole structure will beheated and thus the walls of the chamber 64 will become hot. The air, in passing forwardly in the passages 76, will be preheated before discharging through the throats 7.9 into the mixing flue 78. By this arrangementa more combustible gaseous mixture will be rtxiluced.
The manifold section 60 ras a central opening or port 86 overhanging the rear end of the flue 78 which is curved upward toward said port. The domeSO is continued into the manifold section, as is shown in Figs. 15 and 18, so as to increase the preheating operation, it being understood that the hood TQ co-acts with the chamber inheriting the air and gaseous mixture. .Itwill be seen that the manifold section 60 inclines upwardly from the port 86 toward each end. The top section .61 of the manifold is provided with the burner bosses 27 and ports 26the same as in the other forms. 9 i
Various changes in the size and shape of the different parts, as well as modifications and alterations, may be, made within the scope of the appended claims.
