UNITED STATES BARTHOLOM'EVV GOMMENGINGER, OF ROCHESTER, NEW YORK.
IMPI-(OVEMENT IN HOT-AIR FURNACES.
Specification forming part of Letters Patent No. 116,701, dated July 4, 1871.
To all whom fit may concern:
Beit known that I, BAnTHoLoMEw GomrEN- GINGER, of the city of .loc-hester, in the count-y of Monroe and State of New York, have invented a certain new and useful lmprovenient in Furnaces, of which the following is a specilication:
This inventionconsists in combining, with the hot-air chamber' of the furnace, a system of hotwater pipes, by which the heat in said chamber is equalized and increased.
In the drawing, Figure l is a horizontal section of my furnace through the water jacket 5. Fig. 2, a central vertical section Fig. 3, a view showing the rings of the water-jacket; Fig. 4, a plan of the ash-pit and its extension, showing more particularly the register for the admission of air to the tire.
A is the outer and B the inner' wall of the furnace, the latter inclosin g the hot-air chamber O, from which the heat is distributed. l) is the firepot, E, the grate; and G the ash-pit, having an extension, H, which extends out through the walls in the usual way. Through the top of this extension is made a series of draught-holes, a. a, within the hot-air chamber, and these holes are ctn-*ered by sliding in the register b, which has a stem extending outside the furnace-walls. The walls of the ash-pit are made hollow, to form a waterjacket, l. This jacket may be made in a single chamber, as in Fig. 2, or in the forni of two or more rings, I l', as in Fig. 3, in which ease they are placed one on top of another loosely, each ring being independent from its fellows, and ea ch having a system of pipes extending through the hot-air space, as will presently be described. ln furnaces of large size and capacity it maybe desirable to construct the water-jacket in separate rings in. this way, and the furnace may thus be built up to meet the requirements of the case. By placing it in the walls of the ash-pit Iand sinking the grate therein, as shown, a very large water-surface is attained, and the lire comes in direct contact therewith. Vith each ring ofthe Water-jacket is connected a complete system of pipes, K K, which circle in any desired manner through the hot-air chamber all around the furnace proper. These pipes start from the top of each ring, as shown at d, and, after making the circuit, return at the bottom, as shown at f, thus insuring a complete and constant circula-tion of the water. The object of this arrangement is to increase and equalize the heat. in the air-chamber O by extending the coils in all directions. A great difficulty in common furnaces is that the radiation is principally opposite the fire-pot and the lower part of the furnace, which gives an unequal temperature. The hot-water pipes by permeating every part cause an even and uniform temperature. lff desired, the hot-water pipes may be extended beyond the furnace, and made to heat distant rooms. The pipes are connected with a water-tank, L, by means of branch pipes g lz, the former of which furnishes the supply, while the latter serves simply as an exhaust-pipe for the steam. This tank serves as a fountain to the water-jacket, and also as a warm-water tank for ordinary use. A steam-cock, k, Vis connected with the pipes inside the air-chamber, and employed to inject steam into the hot air for the purpose of moistening it.' It is common to use water-basins for the purpose of eyaporation.
The draugh t-air for supporting the combustion is drawn directly from the hot-air chamber or space C, through the holes a. or any equivalent liue-1. assage, as such a-ir combines readily with the lire, and, by its burning, prevents the forming of clinkers, which is a great difhculty in heatin g-furnaces. There is also a great saving of fuel, as the airis warmed before it reaches the fire. ln this manner a perpetual fire is sustained.
XVhat l claim, and desire to secure by Letters Patent, is-
l. Constructing the water-jacket in two or more separate rings, capable of being placed one upon another, and each having a separate system of pipes, in the manner and for the purpose specilived.
2. The combination ofthe water-j acket I, waterpipes K K', steam-cock K, branch pipes g h., and water-tank L, substantially as and for the purpose set forth.
B. GOMMENGINGER.
