Application ldl April 1.3, 1925. Serial No. 22,709.

To all whom it may concev -nseries forming an iron lioor from the inner Beitknown that I, Femmine/KS. Brrsoom face ofy the wall l to the inner face of the a. citizen of. the United `States, residing at wall 2. Los Angeles, in. the county of Los Angeles Openings 7 are formed through the chanand State ofGalifornia,y have invented new nel bars 6. at the transverse centers and and useful Improvements in Furnaces, of evenly spaced apart and forming longitudir which the following' is a specilication. A nal and transverse rowsras .shown in Fig; 2. This invention relates to gas and oil The gas pipe 8 feeds the longitudinal rows burner furnaces and consists of the novel 9 and 10. The gas pipe lll feedsthe long-rV 10 features herein shown, described land claimed. Specifically the' invention rela-tes principally to the gas burner construction. An object is to make a gas burner confeeds-the longitudinal rows andl.

Fig. 3 is an enlarged fragmentary sectional detail on the' line .3f-3 of Figs. l and 2.

Fig. 4 is an enlarged fragmentary sectional detail on the line 4 4 of Fig. 3.

The details of construction and operation are as follows: n

The furnace has brick or concrete sideV walls land 2, an I beam 3` connects the side Walls l and 2 near the fro Vt anda simi-V lar I beam 4 connects the `side walls at the rear of the gas burner. An angle iron .is mounted below the I, beani 3.A Channel bars- 6 have their side flanges cutaway and the.. channel bars are. turned with the side liaiiges downwardly and mounted nponthe I bea-m4 and angle iron 5 ldngitiidinalof the furnace, parallel with inner facesof v the walls land 2. J There is a series of channel irons'y 6 fitting together side by side as shown in Fig. 3, the

24 and 25 form thelower parts ofthe mixing chamber of the burners.

SquareI blocks 32 and 33 are formed of resuitable fire clayor the like and have recesses 34 and 35 in their lower faces andvertical openings 36 and. 37 in their centers. The recesses 34 and 35 lit the flanges 26 yand 27 -36 and 37 register with thc openings 38 and 39 through the tubes 24 and 25" 'and form the upper. parts; off the mixing chambers of the burners. y Y l After vthe blocks 32 and have been properly placed upon the platform forined by the channels 6, suitable plaster 40 isinserted in the crevices between the blocks to make a lsolid mass. Spacing blocks 4l, 42` and 43 are1 placed. upon the blocks 32 and, 33, and sjfracedA away frolnthe epenin'gs 36 and 37 and baillelblocks 44 and 4.5 .are placed upon the blocks' 4l, 42 and directly' across the openings `se and 3 7 se that-the; gas; and

ings-,316 alla, a7 win strike the baffles ciy and 45 and spread and pass upwardly through the spaces 4K6 and 47 between the baties.

fractory material, that is they are cast of to hold the blocks in place, and the openings Haine passingnpwardly threughjtheA epenim neeacas rIhe construction above set up is repeated over and over throughout the length of the gas pipe 8 and throughout the lengths of the gas pipe 1l and 14, thus producing a comparatively large bank of burners as required in a boiler setting or the like, the burners being on a horizontal plane and the fire from the burners discharging upwardly into the combustion chamber 4S from a horizontal plane 49. The bank of burners is held elevated above the bottom of the furnace and air is supplied to the burners through the adjustable door 5l.

In Fig. l I have shown a combination oil burning furnace and gas burning furnace, although it should be understood that the oil burning feature may be omitted. When the oil burning feature is used the oil pipe 52 may pass through the front wall of the furnace under the bank of gas burners to near the back wall 53 and upwardly, and the oil burner 54 mounted upon the upper end of the pipe to discharge forwardly into the combustion chamber 48. The passage of fresh air to the oil burner 54 may be regulated by the adjustable door 55 and the further supply of fresh air to the combustion chamber 48, thru checkered or perforated floor formed by the bank of gas burners, may be regulated by an adjustable door construction 51.

Heretofore in combination oil and gas burners it has been usual to make the bank of gas burners incline downwardly and backwardly from the front, and a special feature of my construction consists in making the bank of gas burners on a horizontal plane as shown and described.

Special attention is called to the following features:

The gas combustion or mixing tubes have metal sleeves forming their lower parts and refractory sleeves forming their upper parts. I-Ieretofore gas burners have been made with all metal mixing tubes or all refractory mixing tubes.

The refractory portion of the burner combustion or mixing tube is made of a square block in which is cast a round hole. Heretofore refractory mixing tubes have been made round in plan or crosswise. The object in using square blocks is so that they will tit together and form a continuous j'ilatform. or bank.

The square blocks are prevented from moving over the metal furnace floor by means of recesses in their lower faces to tit the tops of the iron sleeves.

The baffles over the combustion or mixing tubes are made interlocking to prevent movement of the baffles by expansion and contraction under heat and cold. This interlocking feature of the baflies is shown in the left hand part of Fig. rilhe corners of the baies are notched and spacing blocks t have corners fitting in these notches. The spacing blocks 56 rest upon the blocks 4l, 42 and 43 while the bafes extend across the openings from one block to another and the spacing blocks serve to hold the battles from moving laterally relative to the openings.

I consider the horizontal feature of the bank of gas burners important. I-Ieretofore it has been usual to distort the bank of gas burners to accommodate the use of the oil burner, that is the bank of gas burners was made upon an incline plane, highest at the front and lowest at the rear.

rIhe furnace is provided. with an adjustable air regulating door for the gas burner system and an entirely independent air regulating door for the oil burner system.

In my construction I have a separate air inlet for the gas and the oil burners. The pan extending from the I-beam 4 to the front of the furnace forms a passage for the air through the door 51 to the gas burners, whereas the air to the oil burning furnace passes through the lowermost damper in the furnace wall.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

l. In a furnace, a bank of gas burners comprising a metal platform having a series of vertical openings, metal mixing tube sleeves inserted downwardly through the platform and having stops to engage the platform, refractory sleeves having recesses in their lower faces to receive the upper ends of the metal sleeves, the refractory sleeves resting upon the metal platform and formed of square blocks approximately fitting to form a ycontinuous bed, and plaster inserted in the crevices between the blocks.

2. In a furnace, a bank of gas burners comprising a metal platform having` a series of vertical openings, metal mixing tube sleeves inserted downwardly through the platform and having stops to engage the platform, refractory sleeves having recesses in their lower faces to receive the upper ends of the metal sleeves, the refractory sleeves resting upon the metal platform and formed of square blocks approximately ttiug to form a continuous bed, and plaster inserted in the creviceS between the blocks. sl'iacing blocks resting upon the sleeve blocks, baille blocks resting upon the spacing blocks crosswise of the sleeve openings, and spacing blocks between the baffle blocks to hold the baffle blocks in place.
