.To all whom it may concern/.1
Be it known that l, JAMES M. HEVERLY, a
'citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Furnaces, of which the following isa specification, reference being had therein to the accompanying drawing.
My invention relates to improvements in a combined hot air and hot water furnace.
The object of my invention is to rovide a furnace of this character which is adapted to be used as a combined hot air and hot water heating furnace, and in which the air and water are more thoroughly heated than in furnaces of this character.
Another object of my invention is to provide a simple, cheap and effective furnace, as
will be hereinafter more fully described and shown in the drawings.
In the accompanying drawings, Figure 1, is a perspective'view of my improved furnace 'showing the casing broken away, and showing in dotted lines the smoke flues in the inner casing. Fig. 2, is a vertical longitudinal sectional view showing one of the side plates removed, and showing the interior of the fire pot. Fig. 3,'is .a vertical longitudinal the center of the furnace. Fig. 4, is a transverse vertical sectional view taken on the line /y--y of Fig. 3. Fig. 5, is a transverse vertical sectional view taken on the line of Fig. 3.
Referring now to the drawings, 1 represents my improved furnace which, as shown, is made of a rectangular form' although the same could be made. of any desired form. The said furnace consists of a base 2 upon 4o which is mounted the outside casing 3, and
which has an inside casing`4 therein, which, as is well understood, is smaller than the outside, casing, leaving the hot air space 5 between said casings, and entirely surrounding the inside casing. The said hot air space is provided with a cold air supply of anycharacter, and by means of whic cold air is fed from the outside to the hot air space 5. In communication with said space 5 above the 5o inside casing is a pipe Sleading to the room to be heated, and while I have shown but one of these hot air pipes it is understood that there is a separate pipe for each room to be heated.
The inner casing 4, as shown, rests u'on the base within the outer casing,.and sai inner casing is formed of the end plates 9 and 10 supporting the top plate 11. The said casing 1s closed by the enlarged side plates 12 ,and 13, which are firmly clamped together by the bolts 15 passing transversely through the frame and provided on the outside of t e side plates 12 with nuts 16, whereby the sevl eral plates are firmly clamped together to form the complete inner casing.
The plates forming the inner casing are either cast or stamped of sheet metal, and the frame above the base is provided with a horizontal plate 17 which is provided with a central opening 18 in which are mounted the grate bars 19, and as shown, form the firepot 20 above and the ash pit 20 below. The end plate 9 above the plate 17 is provided with an opening the door casing 23 which extends out through the casing 3, and is provided with a door and by means of which access is had to the lire pot. The plate 17 adjacent its rear end and eyond the grate, is provided with a transverse vertically-extending plate 24 which forms the rear wall of the fire-pot.
The end plate 9 above the fire-pot is provided with the two inwardly-extendin horizontal plates 26 and 27 which are of a ength to extend nearly across the entire frame, and
connected together at their rear end by a vertically-disposed plate 28which is in a -vertical alinement with the plate 24. The said plate 28 extends downward below `the lower plate 27, and 28, and leaves a space 29 at the rear above the fire-box through which the gases and smoke pass to the vertically-arranged flue 30.
The plates 26 and 27, as shown, are of a width to extend across the stove and form a tight joint with the side plates 12 and 13, and thus form an air space 31 within the inner casing intermediate its top and bottom. The said space adjacent its rear end, is provided with a tank 32 which is of a width slightly less than that of the plates. The said tank is water-tight and adapted tohold water, as will be hereinafter more fully described. The said plates 12 and 13 opposite the air-space 31 are provided with the elongated openings 33 and 34, oppositely arranged. The openings 33 and 34 are adjacent thejforward end offgtheairjspacegandjjestablishilaj'communca- IOO tion directly through the casing for 'allowing air within the hot-air space to pass therethrough and to become heated more thoroughly. The openings 33 and34 are arshown, 1s 1n communication with the vertical gas or smoke iiue 30 at one side through an opening A which is at one side of the space. Theend plate 10 of the inner casing has an opening 38 communicating with the space 37 on the opposite side from the opening A. The stove pipe 39 is in communication with an opening 1n the casing and extends outwardly through the outer casing 3 to the chimney. The said opening A, as shown, is at one side of the space 37 and the smoke pipe at the opposite side, and extending from the rear wall 10 forwardly between the two openings is a vertical division plate B which extends from the upper end of the outer casing to the partition or plate 27, and by means of which the space between the same is divided into two horizontal passages 37 and40. The said plate B has its forward end cut away, as indicated at 41, which forms a communication between the passages 37 and 40, as will be hereinafter more fully described. The gases, smoke, etc, pass upwardly through the passage 30 through the opening A, and into the passage 37, and travel forward across the upper face of the tank, and hot air passages and through the opening or cut-away portion 41, and travel rearwardly through the passage 40 and out the stovepipe, thus increasing the len th of passage of the smoke and gases, where y the upper, rear and lower faces of the hot air space and tank are directly affected by the heat of the products of combustion. l
The end plate 9 opposite the upper space 40 is provided with an opening 42 having a door 43 and forming the damper to regulate the draft to the fire. It will be seen that when the door is opened the air passes from the outside to the space 37 and out through the flue 40 yand decreases the draft in the flue 37, and thus 4regulates the burning of the fire.
The ash-space 21 is provided with an outwardly-extending door housing 44 which ex tends outward through the outer casing and is provided with a door 45 by means of which the draft to the furnace is regulated by means of the damper 46. By means of this it is also understood that the ashes are removed from the furnace. The door 23 is also provided with a damper 47.
When it is not desired to use the hot water heating system, the pipes 35 and 36 are removed and the air passes through the tank,
the same as through the space in front of the same, and thus adds an additional heating surface for the air.
From the foregoing description, it will be seen that the air within the space 5 is more thoroughly heated, as the air has a larger heating surface, owing to the passages through the inner casing.
' Having thus described my invention, what I claim and desire to secure by Letters Patent, is z* 1. A furnace of the character described, comprising an inner and outer casing` forming a hot air s ace between the same, a grate within the lbwer end of the inner casing, a horizontal air passage intermediate the grate and the upper end of the casing, and of a size to leave a vertical smoke flue at the rear of' the casing, the said inner casing having openings opposite the horizontal passage and forming communication between the same and the hot air space, a tank within said passage, pipes connected to the tank and passing through the openings in the inner casing, and through the outer casing, and adapted to be used for hot water heating purposes, and divisional plates carried by the upper face of' the horizontal air passages to cause the products of combustion to travel twice across the same before entering the smoke pipe.
2. A furnace 0f the character described, comprising an inner and outer casing forming a hot air space between the same, a grate within the lower end of the inner casing, a horizontal air passage dividing the inner casing intermediate the grate and the upper end, and cut away at one side at the rear to form a smoke flue, the inner casing having oppositely arranged openings opposite the air pas sage, and forming a communication between the same and the hot air space, a vertically arranged plate extending from the rear wall of the casing at the inner edge of the smoke flue, and extending partially over the air passage and dividing the space above the air passage into two horizontal passages, substantially as shown. 1
