GAS HEATER Filed Feb. l, 1933 3 Sheets-Sheet 3 Patented Nov.l 28, 1933 f UNITED STATES, PATENT OFFICE 1 ""GAs HEATER lBenjamin Bartlebaugh, Wheeling, W; Va. Appiicatin February 1, 1933.` vsare-1 No. 654,705l j sc laimfs: (o1. ies-9o) The present invention is directed to improvements in gas heaters. v A A The invention has vfor one ofitsobjects to'provide a gas heater so constructed that all unburnedgases escaping from 'the burner will be effectively Vmixed with incoming fresh air to eliminate any possibility of the unburned gas being discharged into the space to be heated.

"Another object of the invention is to provide l0 aheater of this character constructed in such a manner that fresh air is mixed with gas'escaping from the burner and the mixture of unburned gas and the fresh' air is compelled to pass to the flame :jets of theburner in order that the unburned gas will be positively consumed, and will not -be-dischargedinto lthe room with the heated fresh air. Y

Still another and important object of the invention is the provision of a main air heating unit sov constructed that the fresh air will -not onlybe effectively heated before entering the room, but the air heated in the unit will as it is dischargedv therefrom greatly aid in drawing, fresh air from the lower end of the heater as the heated air isdischarged from the unit.

` With these'and other objectsin View, ihis invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinaftermore fully described,

claimed and Villustratedy infthe accoinpanyingv drawings, in Whichz Figure 1 is a front view of the heater. Figure 2 is a rear view thereof. Figure 3 is a sectional view on line 3 3 of Figure 1.

Figure 4 is a sectional view on line 4-4 of Figure-1.

Figure v5 is a perspective view of the mainair heating unit.

Referring to the drawings, 1 designates a` casing consisting of inner and outer laterally spaced end Walls 2 and 3, respectively, which define air chambers 4, as clearly shown in Fig. 4 of the drawings. 'Ihe front wall 5 is provided with slidable guard grilles 6 guided in the grooves 7 formed'in opposite sides of the front opening 8.

' The back plate 9 of the casing 1A is bolted to the rear of the heater and is provided with a row of horizontally disposed fresh air inlet openings 10. The lower Aedge of the plate 9 does not extend to the bottom of the heater so that an air admission slot 11 is provided.

The heater is supported by legs 12 of such length as to hold the bottom 12 thereof spaced from the floor in order that fresh air may pass to the interior of the heater through the passage 13 Ydened by the firewall 14and partition 15; said wall and partition extending longitudinally of the combustion chamber 16.

The upper edge of the partition 15 terminates in an upwardly and' forwardly inclined wall 17', which in turn terminates in a downwardly and forwardly inclined `wall 18. f

A top'wall 1-9 is mounted above the wall 18 andhas its rear edge bent downwardly to provide a rear wall 20, the lower edge of which bears against the inner surfaceof the plate 9 at a point slightly Ybelow the openings l10.

Upon reference to Fig. 3 it will be observed that the wall` 15 and plate 9 define an air passage 21 which discharges into-the airpassage 22 defined by the wall 17 and 20, and that the re wa1l14 is supported byY an angle bracket 23 clamped to the gas inlet pipe 24 and abuts the burner 24.Y Gas from a suitable source of supply is conducted to'Y the burner 25 through the pipe 26, there being a valve 27 in said pipe to control'the'ow of gas.' The valve 27 is controlled through the mediumof a rod 28 extending along the bottom of the heater, the forward end thereof'being provided with ahandle 29 tofacilitate operation of the rod, as is customary. 1

A 'top 30 is employed and forms in conjunction with the walls 19, 20 and the plate 9 an upper fresh air receiving chamber 31, air thereto being admitted through the'inlet openings 10 and the openings 32 formed in the end walls 2. Vertically disposed air conducting channel members 33 are mounted in the air chambers 4 so'that air can pass freely through the members from the lowermost openings 32 to the uppermost ones.

The side flanges 34 and the front flange .3,5 of

the top 30 are provided with air outlet openings 36.

A-baiie plate 37 is Vsuspended below the wall 18 by brackets 38, and has its inner edge alined with and vertically spaced from the upper edge of the fire Wall 14, there being a passage 39 beu tween said plate and wall.

Fresh air entering the passage 13 from the opening 49 and from the bottom of the heater will be forced by the heat from the'burner into the flame of the burner in a manner to be hereinafter described.

A main heating unit 41 is employed and consists of a plurality of flues 42 secured in spaced relation by a metal sheet 43 riveted to the respective flues.

The unit 41 ismounted between the top wall 19 and the wall 18, as clearly shown in Fig. 3, and is supported in such position by a longitudinally extending plate 43, the longitudinal edges of which are suitably secured respectively, to the fiues 42 and wall 18. The inner ends of the flues 42 rest upon the wall 18 and adjacent the rear end thereof and have direct communication with the air passage 22.

The bracket 23 is provided with a pluralityof perforations 44 in order that air and unburned gas from the passage 13 may enter the combustion chamber i6 and be subjected to the flame of the burner 25.

When gas from the burner 25 is ignitedthe hot unburned gases will ascend and be directed rear- Wardly by the baffle plate 37 and wall 1S, and thence rapidly downwardly by the wall 17 behind the fire wall 14 and into the passage 13. rlrhe hot non-consumed gases will rapidly ccmmingle with the air in the passage 13 and this mixture of air and gases is then blown through the perforations 44 with considerable velocity, and this mixture is directed under pressure into the ascending flame of the burner, thereby positively burning the unburned gases to` eliminate, the discharge of unburned gases into a room. As long as the burner is in loperation this cycle takes place and the discharge of obnoxious odors and dangerous gases into a room is positively prevented.

Obviously heat in the combustion chamber 16 will heat the baffle plate 37, wall 18 and plate'43 and is transmitted to the flues 42, which are located at the hottest point of the heater. After the ues have become well heated, and dueto their location, the air heated therein rapidly discharges, and due to this rapid discharge of heated air a rather strong suction is created in the passages 22 and 21 which willdraw fresh air from the bottom of the heater into the iiues.

Heat from the flues 42 will heat the walls 19 and 20 to a considerable extent, and consequently fresh air entering the chamber 31 through openings 10 and l22 will Vbe heated and discharged through the openings 36 of the top 30.
