FRANK WAITE, OF LONG ISLAND CITY, NEW YORK.
FURNACE ARCH.
Application filed August 31, 1920. Serial No. 407,246.
To all whom it may concern:
. Be it known that I, FRANK H. Warm, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Furnace Arches, of which the following is a specification.
This invention relates to furnace arches and is designed as an improvement over my prior Patent No. 1330925, dated February 17, 1920.
The prlmary object of the invention is to provide an arch which will be constantly cooled by a free circulation of a1r 1n order to maintain the arch below the fusing point at all times, at the same time not materially increasing the cost of manufacture and installation of the arch or in any way incumbering the same or retarding its use.
The above and other ob ects of this 1nvention will be in part described and in part understood from the following descriptlon of the present preferred embodiment of the invention, taken in connection with the ac-' companying drawings, wherein:
Fig. 1, is a vertical sectlonal view of an arch constructed in accordance with my invention illustrating its application.
Fig. 2, is a fragmentary top plan view of the arch showing the hangers in section, and illustrating the manner of mounting the arch in the furnace.
Fig. 3, is a transverse sectional view of the arch taken on the line 3-3 of Figure 1 illustrating its application and showing to advantage the hangers, and
Fig. 4, is a transverse sectional view of the arch, taken on the line 4-4 of Figure 1 illustrating its application and showing to advantage the air duct therethrough.
In the drawings, a furnace generally designated 5 is shown which includes side walls 6. Each of the sidewalls is provided with an air channel 7 on its inner face which extends rearwardly from the front of each wall and terminates at a point remote from the rear of the furnace. The dotted lines in Fig. 1 show the air channel 7 on one side of the arch.
The arch is generally designated 8 and is of a flat construction as shown to advantage in Fig. 1. The arch consists of a plurality of blocks 9, the ends of which are correspondingly cut out, as indicated at 10 and shown to advantage in Fig. 4, to permit interengagement of the blocks. Each block has a duct 11 formed therein adjacent its upper face whereby when the blocks are assembled in end to end engagement, as shown to'advantage in F ig. 4, a continuous pas sage-way is provided which communicates with the channels 7 in the walls of the furnace. In this way the influx of air through said channels will be' "permitted to circulate through the passage-way in each series of blocks in order to aid in cooling the same.
A portion of the upper face of each block is removed to provide a groove as indicated at 12, the groove on each end of the blocks communicating to provide a canal 13. A tubular hanger 14 of U-shape construction is mounted in each canal. Each of said hangers comprises two parts to facilitate assemblage thereof in the canals. The inner ends of the parts of each hanger are contiguous, while the outer ends extend upwardly an appreciable distance and are bent at right angles, as indicated at 15, to overhang supporting bars 16. The supporting bars 16 are mounted in the side walls of the furnace, and are secured in any desired manner. Upon reference to Fig. 30f the drawings, it will be noted that the end blocks which embrace the sidewalls of the furnace have right angled hangers therein as indicated at 17. One end of each of these hangers extends into one of the air channels/7, while its opposite end extends u wardly and over one of the hangers 16. f course, the terminal blocks which carry these terminal hangers 17 are correspondingly formed. It will be-noted that the outer terminals of the hanger 17 extend for an appreciable distance into the channel 7 to facilitate baflling of the air into the air ducts 11.
It will be apparent from the above that the device of this invention consists of a fiat arch especially adapted for use on stokers, furnaces, or in any other capacity where a fiat arch is used. By constructing the hangers in the manner set forth above it is apparent that they may be readily assembled and will project above the arch so as to receive the atmosphere thereinto for individually cooling the blocks of the arch. Moreover, by providing air ducts in the blocks continuous air passages are formed in each series of blocks communicating with air channels in the side walls of the furnace, the latter also opening to the outside for receiving fresh influxes of air. Moreover, when the temperature is high blowers may be used for forcing an air current through the air channels and ducts.
What is claimed is:
1. A furnace arch in'combination with side walls having longitudinally extending air channels therein, an arch comprising series of blocks, each series consisting of a plurality of inter-engaged blocks provided with a continuous air passage way therethrough the terminals of which open into said air channels, and tubular hangers mounted in said blocks with their terminals extended to a point above the latter substantially as described.
I 2. A furnace arch including blocks interengaged in end to end relation and arranged transversely in the furnace, a pair of tubular hangers inserted through the ends of each block and bent upwardly at right angles to terminate at a point above the blocks, substantially as described.
3. A furnace arch, in combination with the side walls of the furnace provided with air channels extending from the front of the walls to a point remote from the rear of the latter, an arch consisting of a plurality of blocks arranged in end to end relation and extending from one side of the furnace to the other, said blocks having air ducts therein communicating with the air channels in the furnace walls, and a hanger for each block to support the latter and provided with an air canal to cool the same.
