Application filed March 24, 1921. Serial No. 455,031.

heating purposes, it being the object of the invention to improve upon prior types of furnaces 1I1 simplicity of construction, and in reduclng the number of parts. It is an object of my present construction to improve,

several features of existing types of furnaces inproviding easy means for cleaning out the passages which form the radiator of the furnace, the parts being so arranged that the dirt may be removed and dropped directly into the fire box. A further object is to shape and design the parts so that a separate fuel feeding passageway and door opening may be avoided.

In constructions which have preceded my invention, a separate fuel .feedingpassageway or pouch has been secured to the front of the radiator and combustion chamber, but

owingto the rapid changes in temperature and uneven expansion of the parts in the firing of the furnace, the bolts for holding the fuel feeding passageway-in place have often been sheared off by the movement of the parts. It is one of the principal objects of'this invention to do away with a separate element to form the fuel feeding'passageway so that faulty construction will be avoided.

In the drawings which accompany this applicationfthere is shown. the upper sections of the furnace, the lower portions and the casing being ofany standard or'well known construction and therefore, not being illuse portion of the furnace'looking'in at the door opening or fuel feedlng passageway.

V Fig. 2 is avertical section across the upperpart of the furnace on the. llne 22 of F 1g. 3.

F 3 is a vertical section on the line of F 1g. 1. g

Fig. '4: is a horizontal section on the'line 4-4 of Fig. 3, looking down on the lower.

radiator section.

The furnace is built up of a plurality of cast iron sections as is usual, comprising a fire box 1, the upper edge of which is provided with an offset flange 2, in which is seated the lower edge of the combustion chamber 3.. I

The upper portion of the combustion chamber is curved or arched inwardly, and around its upper edge is formed a channel. orgroove 4. Above the combustion chamber is located the radiator which is made in two sections divided on a horizontal plane.

The lower section of the radiator is designated by the numeral 5 and the upper section by the numeral 6, the lower edge of the uppersection being provided with an offset flange 7 which surrounds the upper edge of the lower section, the two sections being pro vided with registering lugs 8 through which pass bolts 9, holding the two sections together. The radiator shown in the drawings is .ofthe horse-shoe type, being provided with a centrally located dome 10, curved smoke fiues 11 and a smoke pipe collar 12,

through which the products of combustion pass to the chimney The smoke fines are open at the front as at'13'andare'easi1y accessible from the door opening. Incleaning out the radiator the soot may be raked to the front of the fines and will drop directly into the fire box. p The fuelpassageway and door opening, which is-indicated by the numeral 14 is formed integral with other parts of the furnace which have been described, this being one of the important features ofmy inven- 1 tion as it does away with the separate'pieee or element to form a fuel feeding passage way, a feature not found in prior furnaces of this type. This fuel feeding passageway is formed by extending from the front portion of the combustion chamber 3 a U-shaped or channel-shaped flange or extension 15 which forms the lower half of the fuel'feeding passageway and providing. the lower radiatorsection 5 with a mating U-shapeol or channelshaped extension'16, the two extensions-ta.

getherforming' the fuel feeding passageway or door opening, as shown in Fig. 1.

Thegroove or channel 4 is carried around on the upper edge of the part 15, so that the extension in the radiator may seat therein. Across the front of the extension 16 is car ried a pin 17 which swingingly supports a door or shutter 18. The shutter 18 directs the products of combustion'into the flue 13 and diverts them from the upper portion of the door opening.

It will be understood that the furnace outer casingis placed around the furnace in the usual manner, as shown in dotted lines in Fig. 4: at 19. Midway of the fuel feeding passageway 14 are a number of lugs 21 which are used for supporting the inner casing 22, should it be desired to use this furnace in the double casing or pipeless construction. j

The operation and advantages of the improved furnace will be readily understood and appreciated. The smoke flues 11 are easily cleaned out by reason of the access provided from the door opening into the flue openings 13. In prior constructions of this type, the extension which forms the door opening and fuel feeding passageway was made in a single piece separate from the other parts of the furnace and secured to the body of the furnace by bolts or similar means. As a result of the rapid and violent expansion and contraction to which these parts are subjected, in the operation of the furnace, the holding means would often be broken or loosened. In the furnace embodied in this invention however, the fuel feeding passageway is made integral with the body of the furnace, by forming it from two extensions, the one on the combustion chamber and the other on the lower half of the radiator and the breakage due to the action obtained in the separate construction of the fuel feeding passageway is avoided. By forming the two sets of lugs 20 and 21, the former for the front and the latter for the inner casing, the furnace is adaptable for either the pipe or pipeless construction.

It is obvious that changes and modifications may be made and form and proportion are not essential to the invention herein disclosed, but may be varied without departing from the invention or sacrificing any of its benefits.

I claim:

1. In a furnace construction, a combustion chamber, a radiator above the combustion chamber, said combustion chamber being open atone side thereof, an integral extension about the opening to form a part of the 'fuel feeding passageway, and means connected with the radiator located over the extension from the combustion chamber to complete the fuel feeding passageway.

2. In a furnace construction, a combustion chamber, a radiator above the combustion chamber, the combustion chamber and the radiator being open at one side, an integral extension about the opening in the combustion chamber, and an integral extension about the opening in the radiator, the said extensions together forming a fuel feeding passageway.

3. In a furnace construction,a combustion chamber, a radiator above the combustion chamber, said radiator being open at one side, the flue openings for said radiator being open adjacent the aforesaid opening in the radiator, and an integral extension about the radiator opening forming a por tion of the fuel passageway.

l. In a furnace construction, a combustion chamber, a radiator above thecombustion chamber, said radiator being open at one side, the flue openings for said radiator being open adjacent the aforesaid opening in the radiator, the combustion chamber being ope-n below the radiator opening and forming therewith a feed opening and an extension about the feed opening forming a feeding passageway, said extensionbeing in two parts integral with the combustion chamber and the radiator.

5. In a furnace construction, a combustion chamber, a radiator above the combustion chamber, said radiator being open at one side, the flue openings for said radiator being open adjacent the aforesaid opening in the radiator, anintegral extension about the radiator opening forming a portion of the fuel feeding passageway, and a shutter traversing said extension.

6. In a furnace construction, a combus tion chamber, a radiator above the combustion chamber, said radiator being open at one side, the flue openings for said radiator being open adjacent the aforesaid opening in the radiator, the combustion chamber being open below the radiator opening and forming therewith a feed opening, oppositely faced U-shaped extensions on the radiator and on the combustion chamber forming a fuel feeding passageway, said extensions being integral with the radiator and the combustion chamber, respectively.

7. in a furnace construction, a fuel feeding passageway extending outwardly from the combustion chamber, said passageway being formed throughout its entire extent from the door opening to the furnace body by integral extensions from the furnace body, lugs on the outer edge of the extension adapted to hold the outer casing, and lugs on the extension between the first named lugs and the body of the furnace to hold an inner casing.
