HOT-AlR FURNACE Specification of Letters Patent.
Patented May '7, 1907.
Application filed February 26,1906. Serial No. 803,046.
To a wit/17w 2125 Hwy concern.-
Be it known that I, HARRY F. RAsoR, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Hot-Air Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, uch as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in hot air furnaces, and consists in the novel construction, combination and arrangement of devices hereinafter described and claimed.
One object of the invention is to provide a heater of this character in which the smoke pipe or flue and the hot air pipes which extend through the combustion cham ber will be interchangeable, so that the smoke pipe may be adjusted at any point upon the b ack or side of the furnace to enable the same to be readily set or reset.
A further object of the invention is to im prove and simplify the construction and operati on of furnaces of this character and thereby render the same more efficient and durable and less expensive.
The above and other objects which will appear as the nature of the invention is better understood, are accomplished by the construction illustrated in the accompanying drawings, in which Figure 1 is a vertical front to rear sectional view through my improved hot air furnace; Fig. 2 is a vertical sectional view taken on the plane indicated by the line 22 in Fig. 1;
Figs. 3 and 1 are horizontal sectional views 1 taken respectively on the planes indicated by the lines 3-3 and 1 4 in Fig. 1, and
Referring to the drawings by numeral, 1 denotes my improved hot air furnace, the body 2 of which is composed of a plurality of superposed sections arranged within a surrounding casing or jacket 3 and support ed upon the usual foundation 41. Cold air is supplied. to the casing or jacket 3 through the foundation 4 and hot air is discharged through suitable pipes which project from the top or upper portion of the casing or jacket and lead to different points where the hot air is to be discharged. The body 2 of the furnace comprises a lower or base member or section 5, which is here shown in the form of a casting supported upon the founda tion l. This member 5 comprises a large circular plate 6, from the solid central portion of which rises a vertical wall 7 of semicircular shape, which forms the ash pit of the furnace. The ends 3 of the semi-circular wall 7 extend forwardly to the edge of the plate 6 and are connected at their tops, as shown at 9, so as to form an opening for the ash pit, through which the ashes maybe removed.
The sides and rear of the circular plate 6 are open, as shown in Fig. 4 of the drawings, the rim or edge 10 of said plate being connected to the solid central portion by ribs or spokes 11. The casing or jacket 3 has its bottom attached to the rim 10, and suitable openings and doors are provided in and upon it to aline with the opening into the ash pit, the opening into the fireb ox and other openings, as will be readily understood. Mounted upon the ash pit wall 7 is a frusto-conical ring or wall 141, which forms the fire-box of the furnace and within which is moimted a grate of any suitable construction.
Upon the member 14 of the furnace is supported the upper member or section 23 which forms the combustion chamber. This member 28 consists of three superposed parts or sections 29, and 31, the bottom section 29 being of inverted frusto-conical form and having its lower end mounted upon the top of the fire-box wall 14 and also having at its front a horizontally projecting portion 32, which provides an opening through which coal or other fuel may be inserted into the fire-box upon its grate. The intermediate section 30 of the member 28 is in the form of an annular band or ring which connects the top of the section 29 and the bottom of the section 31, which latter is in the form of a circular cover plate or top. Extending ver tically through the furnace member or combustion chamber 28 are air flues or pipes 33, the upper ends of which are formed with annular flanges 34 to engage seats formed in the under face of the top plate or section 31 concentric with openings 35 therein. The flanges 34 are bolted or otherwise secured in said seats, as shown in Fig. 2. The lower beveled ends of the pipes 33 are formed with elliptical flanges 36, which engage similarly shaped seats formed in the inclined outer faces of the lower section. 29. These flanges 36 surround openings 37 and are also bolted, riveted or otherwise secured in their seats, as shown. Arranged vertically in the member 28 is a smoke flue or pipe 38, which is similar to one of the pipes 33. This smoke line has IIO flanges 39 and at its ends, which flanges are similar to the flanges 34, 36 upon the pipes 33 and are adapted to be bolted or otherwise removably secured in the seats at any pair of the openings 35, 37 in the top and bottom sections 31, 29 of the member 28.
This construction enables the smoke pipe 38 to be adjusted at any point around the member 28, so that the furnace may be readily set or reset. The upper end of the smoke pipe 38 is closed, as shown at 41, but leading from the same at a point slightly below said upper end is a horizontally extending direct draft outlet pipe 42, in which is provided a controlling damper 43 of any desired form and construction. Projecting horizontally from the lower end of the smoke pipe 38 is an outlet pipe 44, in which the damper may also be provided if desired. These pipes 4.4 and 42 roject through the furnace casing and lea to the chimney or smoke stack. In order to render the j oints or connections between the members or sections of the furnace gas and smoke tight any suitable means may be employed.
The construction, use and advantages of the invention will be readily understood from the foregoing description taken in connection with the accompanying drawings. It will be seen that by making the smoke pipe 38 and the hot air pipes 33 interchangeable, the furnace may be set in any position and the smoke pipe may project at any angle therefrom. The manner of connecting the pipes or lines to the furnace sections and the cement joints between the latter render the body of the furnace air tight and prevent the escape of smoke and gases from the same and into the outer casing 3, which confines the pure air which is to be heated. The construction of the grate here shown .and described causes the fire to burn around the center of the body or coal upon it and adjacent to the outer surface of the fire-box and the annular row of hot air pipes. The peculiar construction of the grate also insures a continuous and thorough combustion of the fuel, since air may readily pass through it and the ashes may fall downwardly as the coal is burned.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificmg any of the advantages of the invention, as defined by the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters-Patent is 1. A hot air furnace comprising :a body having a combustion. chamber, and smoke and air pipes interchangeably arranged in said chamber.
2. A hot air furnace comprising a-body having a combustion chamber, and an annular row of interchangeable smoke and hot air pipes arranged in said chamber.
3. A hot air furnace comprising a body having a combustion chamber, the top and bottom of said chamber having vertically alining openings formed therein, seats arranged around said openings, and interchangeable smoke and air, pipes in said chamber between said openings and having attaching flanges to engage the said seats, substantially as shown and described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
HARRY F. RASOR.
