UNITED STATES PATENT OFFICE.
CHARLES L. GEHNRICH, or ELMHURST, NEW YORK, assmnon 'To ennnmcn mnmnc'r HEAT oven COMPANY, or LONG- ISLAND CITY, New YORK, a ooarona- 'I'ION OF NEW'YOBK.
To all whom it may concern:
- An object of the invention is to provide a drum in which the heat conducted by a series of vertical radiator tubes circulates about the air fiues passing through the drum.'
Another object of the invention is to circulate the heated air about the radiator tubes and also about the heat combustion chamber before it is educted' near the bottom of the furnace.
Another object of the invention is to prevent the air from the time it enters the furnace until it is educted in a superheated condition, from getting into contact with the burning combustible or the products of combustion.
The novel features of the invention are more fully described in the following specification and claims, and illustrated in the accompanying drawings in which Fig, 1 represents a vertical section of a furnace embodying this invention.
Fig. 2 is a vertical section taken along the line 2 2 of Fig. 1.
Fig. 3 is a horizontal section taken along the line 3 3 of Fig. 1.
Fig. 4 is a similar section taken along the line 4 4 of Fig. '1.
In the drawings is shown a sectional furnace having rear, front andside walls 5 top wall 6 and bottom wall 7 forming a separable casing of non-conducting material to obviate radiation of the heat. The casing is provided in its lower portion with a combustion chamber8 and fuel such as gas or.
oil is conducted by means of tubes 9 to the interior of the chamber. Each tube has a number of perforations 10 for the ejection of and to ignite the combustible. The tubes are supported on cross bar 11 fixed to the side wall of the chamber. Bafiie plates 12 supported on angle irons 14 spread the Application filed February a, 1925. Serial No. 8,031.
flame so as to prevent it from shooting upard. The chamber is fastened to the bottom of the casing and the walls thereof are spaced fromthe wall of the casing as indicated in Fig. 4, so as to radiate the heat generated in the chamber directly within the casing.
A drum 15 is arranged in the upper part of the casing and itis connected to the coinnor-Am FURNACE.
bustion chamber by means of a series of radiator tubes 16 extending vertically from the top of the chamber to the bottom of the drum. The products of combustion from the burning fuel pass out'through a flue or chimney 17communicating with the interior of the drum. The drum is also spaced from the wall of the casing so as to leave a passage about its top, rear and sides as indicated in Fig. 3, for the radiation of the heat from the drum directly within the casing.
The drum is provided with a series of horizontal air-induction tubes 18 and a flue 19 leads the fresh air from the exterior of the casing into the fines. The air passing through the induction tubes is heated by the hot-air circulating in the drum and then flows into the casing to circulate about the exterior of the drum. The hot-air then descends to circulate about the vertical radiator tubes and the combustion chamber so as to give it a higher degree of heat before it is drawn off through an eduction opening 20 in the lower part of the casing. The air ejected from the opening can be used for drying articles or for heating purposes.
In this furnace the air is not permitted to get into contact with the products of combustion and it receives all the heat radiated by the different heat generating units in the casing.
The air is disintegrated or expanded by being first heated in the drum so that it will more freely circulate about the numerous radiator tubes and no pockets are created. A plurality of deflector plates 21 disposed in staggered formation direct the air in a zigzag course about the radiator tubes so as to incorporate all the heat possible from ing the chamber with the drum, air flues in the drum communicating With the exterior of the casing, and an eduction opening in the casing.
2. A hot air furnace comprising a casing, a combustion chamber located in the bottom of and spaced from the wall of the casing, a drum in the upper part of the casing, vertical radiator tubes connecting the chamber with the drum, air fines in the drum comnmnicating with the exterior of the casing, and an eduction opening in the casin 3. A hot air furnacecomprising a casing, a combustion chamber located in the bottom of and spaced from the walls of the casing, a drum in the upper part of and spaced from the vertical walls of the casing, vertical radiator tubes connecting the chamber with the drum, air, flues in the drum communicating with the exterior of the easing, and an eduction opening in the casin 4. A hot air furnace comprising a casing, a combustion chamber located in the bottom of the casing, a drum in the upper part of the casing, vertical radiator tubes connect-- ing the chamber with-the drum, air fines extending through the drum leading from the a combustion chamber located in the bottom" of the casing, a drum in the upper part of the casing, vertical radiator tubes connecting the chamber with the drum, horizontal air flues extending through the drum leading from the exterior to the interior of the casing, apd an eduetion opening in the lower portion of the casing.
6. A hot air furnace comprising a casing, a combustion chamber located in the bottom of the casing, a drum in the upper part of the casing, vertical radiator tubes connecting the chamber with the drum horizontal air fines extending through the drum leading from the exterior to the interior of the casing, a plurality of deflector plates arauged in staggered formation in the casing coacting with the radiator tubes, and an eduction opening in the lower portion of the casing. 1
In testimony whereof I have hereunto set my hand.
