A iioor 1 is huilt upon joists 2 and a rectangular opening 3 Vis made through the ioor 1 between two joists. An outer shell l 4 is straight up and down, rectangular in plan, and has an out-turned flange 5 at its upper end all the way around so that the shell fits closely in the hole 3 .and the .flange rests upon'the floor 1 aroundthe hole.. The shell 4 is preferably formed `of heavy galvanized iron. `A layer of asbestos paper 6 is pasted to the outer face of the outer shell 4.

A gas feed pipe '7 has a union 8 lupon its end. A T 9 is connected to the other end of the union from the pipey 7. Anipple 10 ex'- tends outwardly from the T 9 and a cap 11 is mounted upon the lower lend of the nipple 10 to make a drip ot. A pipe 12 extends upwardly from the I 9 insideA of one wall of the outer shell 4.

"A double gas cock fitting 13 is connected to the upper end of the vpipe 12. The double gas cock fitting 13 consists of a female nipple 14 screwed upon the end of the pipe 12, a gas cock construction 15 extending one way from' the nipple 14, and 'a as cock construction 16 extending the ot er way from the nipple 14, and ears 17 through' which screws 18 are inserted to secure the fitting against the inner face of lthe outer shell 4 directly below its upper edge.

Movable valve members

19 and 20 havesockets with openings to receive a key 21 so that the key may be inserted into either one of rthe valves and the valve operated and the f key removed.

A reinforcing plate 22 is secured against the inner face of the outer shell 4 byy rivets' 23 and the screws 18 are inserted through vthe vea'rs 17 and tapped into the plate A main supply pipe 24 is connected to the 'l valve construction 16 and extends down-4 wardly to

main burners

25 and 26 and a pilot light pipe 27 is connected to the valve construction 15 and extends downwardly to a pilot burner 28 so that by placing the key 21 in the valve 19 the pilot burner may be controlled and so that by placing thel key 21 in the valve 20 the main burners may be controlled.

A bottom 29 is inserted upwardly into the lower end of the outer shell 4 and secured in place by bolts 30. In assembling the parts the bottom 29 is placed in positionbefore the

pipes

20, 24 and 27 are. placed in position. The details of the bottom 29 are as follows: The bottom 29 is preferably a casting and comprises a rectangularl flat plate 31, and a flange 32 extending downwardly all the way around from the edge of the plate 31. A rectangular opening 33 iS formed through the plate 31, there being a rib 34 extending upwardly all the 'way around the opening 33 a short distance outside of the edge of the opening, thereby forming a ledge 35 all the way around the edgev of the opening. A wall 36 extends downwardly from the plate 31 in vertical alinement ith. the rib 34 to form a -housing around

thevburners

25, 26, and 28, said housing being open atthe bottom to -provide a free circulation of air upwardly through the housing around the burners to the combustion chamber. A circular opening 37 is formed through the` plate 31 at one end of the opening'33, An annular rib 38 extends upwardly from the plate 31 around the opening 37 a short distance outside of the e ge of the plate to form a ledge 39.

Bolt holes

40, 41, 42 and 43 are formed throughv the plate 31.

The details of a radiator base44 shown in Fig. 6 includes the parts v45 to 74 and are as follows: Thebase 44 is an integral casting and has a rectangular housing 45 open at the top and bottom and fitting upon the ledge 35. A circular housing 46 is open at-the top and bottom and fits upon the ledge 39 and a web 47 connects the circular housing 46 to the rectangular housing 45. A iue nipple 48 extends horizontally from the housing 46 at the opposite side from the housing 45. VFlue bottoms 49, 50 and 51 extend horizontally outwardly from the upper edge of the wall 52 of the housing 45 and similar flue bottoms 53, 54 and 'extend horizontally outwardly from the upper edge of a wall 56 of the housing 45. A flue bottom 57 extends from the upper edge of a wall 58 of the housing 45 over the web 47 and Hue bottoms 59 and 60 extend outwardly from the up er end ofthe housing 46 in line with the ue bottoms 49,-

4 50 and 51-and flue bottomsl and 62 extend horizontally outwardly from the up er end of the housing` 46 inline -with the ue bottoms 53, 54- and 55. The

flue bottoms

49, 50, 51, 59, 6o, 62, 61, 55, 54 and 53 are evenly -spaced apart thereby forming air passages 63, 64, and 66 one side of the casting and similar air passa es 67, 68, 69 and 70 on the other side o the casting, Flanges 71 and 72 extend upwardly from the upper edge of an end wall 73'of the housing 45, thereby forming a channel 74 55 between the flanges. The anges 71 and 72 are continuous extending upwardly along the edges of the flue bottom 49, then along the edge of the wall 52, then along the outer edge of the floor bottom 50, and so on all the way around the casting.

The details of the central radiating element 75 as shown in Fig. 5 are as follows:

Y A radiating element 75 is made of sheet metal and vpreferablyv consists of two vmating pieces 76 and 77. The main part of the piece 76 is bent in and out' to form hot air lues 78, 7 9, 80, 81 and 82 fitting in the channel 74 around the

flue bottoms

53, 54, 55, 61 and 62, and forming channel shaped air passagesl 83 between the hot air fluesin line with the

air passages

67, 68, 69 and 70, and

the

air passages

63, 64, 65 and 66.

A partition 90 consists of a flat plate in Serted in the hot air flues 81 and 87 against the walls of the

air passages

83 and 89 which are between the hot air flues 80 and 81 and 86 and 87 and held in place by bolts or rivets 91. The partition is cut short and extends from the bottom of the radiating element 75 nearly to the top thereby leaving a hot air passage 92 over the top of the partition. The/pieces 76 and 77 are connected together by

Vertical seams

93 and 94.

The details of the top plate 95 of the radiator shown in lFig. 4 are as follows: A top plate 95 isa castlng and consists of a main ody 96

havin notches

97 and 98 extending from'its side e ges, an opening 99 extending through one end and surrounded by an upwardly projecting annular ring 100 and bolt holes'101, 102, 103 and 104 formed through its corners. The notches 97 are in line with the air passages 89 in the radiating element 75 and the

air passages

63, 64, 65 and 66 in the casting 44, and projections between the notches 97 Vare in line with the hot air iiues-'84, 85, 86, 87 and 88 and in line with the' flue bottoms 49, 50, 51, 59 and 60. In a like manner projections 106 between the notches 98 are in line with the hot air lues 78, 79, 80, 81 and 82 and in line with the

flue bottoms

53, 54, 55, 61 and 62, and the bolt holes 101, 102, 103, and 104 'are in line with the bolt holes 40, 41, 42- and 43 in the casting 29. A lower face 107 of the top plate 95 is practically a mate to the upper face of the casting 44.

Flanges

108 and 109 extend downwardly all the way around the edge of the casting 95 and form a channel 110 in which the upper edge of the radiating element 75 its. The lower edge of the radiating element 75 ts in the channel 74 in the casting 44.

Stove bolts 111 are inserted downwardly through the bolt holes 101, 102, 103 and 104 and through the bolt holes 40, 41, 42 and 43 and nuts are placed upon the lower ends of the bolts to hold the outer shell bottom 29, the base 44, theradiating element 75 and the top plate 95 securely together.

A cap 112 fits upon the annular ring 100 and thecap 112 consists of an inner member 113 fitting within the annular rin 100; an outer member 114 fitting outside 0 the ring 100; a mica plate 115 fitting between the members 113 and 114; and a andle 116, all the parts being secured together by bolts 117. The member 113 is L-shaped in cross section and has a flat upper face upon which the mica plate 115 rests. The member 114 has a flat lower face fitting upon the mica plate 115-and extends downwardly and outwardly to form a channel 118 to receive the ring 100.

A register frame 119 fits upon the floor 1 over the flange 5 and ears 120 extend inwardly from the frame and screws 121 are inserted downwardly through the ears and tapped into brackets 122 secured to the inner face of the outer shell 4. Agrate 123 extends inwardly from the frame 119 all the way around to make a rectangular opening 124, there being a ledgeA 125 extending inwardly all the way around from the o e-ning 124. An intermediate casing 126 is ormed of sheet metal and the upper end of the casing 126 is reduced in size and inserted upwardly through the opening surrounded by the ledge 125 andthe upper edge of the casing is turned outwardly to form a flange 127 fitting upon the ledge 125 so as to support the casing 126. The casing 126 extends downwardly to a point half way between the top and the bottom of the casting 44, thereby forming a cold air passage 128 leading downwardly through the grate 123 between the outer shell 4 and the intermediate cas-- upwardly outside of the radiator 75 and inl side of the intermediate casing 126. A flue 130 is attached to the nipple 48 and extends outwardly through the outer shell 4.and up'- wardly to any desired position. A register grate 131 is loosely mounted within the grate 123 and upon the flange 127 to cover the radiator so that when desired the register 131 may be removed and the cap 112 removed to light the pilot 28.

For the purpose of lightin the pilot 28 I employ7 a match holder 132 ormed of wire comprising a handle 133, a lon stem 134 and a coil 135. A lighted matc 136 may be pressedbetween the strands of the coil 135, the handle 133 manually grasped and. the match holder inserted downwardly through the cap hole 99, then the key 21 may be operated to turn on the gas to the pilot '28. As soon as the pilot 28 ignites the cap 112 may-be replaced and the grate 131 replaced, then the key 21 may be operated to turn on the gas through the pipe 24 to the

burners

25 and 26. The fresh air will pass upwardly around the burners within the wall 36, then the hot air and products of combustion will pass upwardly through the housing 45 and upwardly through the radiator 75 above the housing 45 and through the hot air passage 92 over the top of the partition 90 and downwardly through. the radiator `to the housing 46, and then outwardly through the nipple 48 and through the flue 130. Fresh air will pass upwardly 'through the opening 37 to the ousingf46 and mix with the products ofv casting'44 and will pass upwardly inside of the casing 126 and through the passage 129 and around the radiating element and top plate 95 and then the hot fresh air will pass upwardly through the register 131 to warm the room. By removing. the screws 121 the grate 123 carrying the intermediate casing 126 and the grate 131 can be removedv to provide access to the interior of the outer shell 4 and the furnace can be thoroughly cleaned from the floor 1 and the

parts

19 and 20 can be oiled and repaired.
