Application filed October 20, 1924; Seritil'No; 744,762.
This invention relatesv to improvements in furnaces, the general: object being to'provide means whereby aradiator part or a feed part formed of steel or the like can be con-- nected to a fire pot part'without dan eriof the connection being broken througli the diii'erent expansions ofthe two parts.
Another object of the invention is to make a fire pot of steel and cast iron, the parts being so arranged that the fire pot can expand underthe action of the heat without breaking the cast iron parts, these parts protecting the steel parts from damage.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustratcd in the accompanying drawings and specifically pointed out in the appended claims.
In describing. my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional. view through a furnace constructedlin accordance with this invention. 7
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a sectional dii' feiient form.
Figure iis a sectional view through an other form of the invention;

Figure 7 is a view of a further form.
Figures 8 and 9 are detail views showing how the cast iron sections can be attached to a steel section.
Figure 10 is a section on line 101O of Figure 9.
Figure 11 is a sectional view through a fire pot formed of cast iron sections and a steel jacket.
Figure 12 is a section on line 1212 of Figure 11.
In the first form of the invention the radiator 1 is formed of steel while the firepot section 2 is formed of cast iron or material which will not be affected by the heat and in order to prevent the greater expansion of the steel radiator from effecting its connection with the firepot section, the metal of view of a slightly which doesnot expand as much as the steel will'l provide the radiator with a depending conical part 8 which telescopes a conical part at of the fire pot section and: thus permits movementfiof one part on the other under the expansive action. I also place a split ring: 5 in. the. conical part 3 at a slight distance-above the part 4 which acts to steady the radiatorsectionv This collar may be of steel or castiron.
Thus the parts land 2 can be made of materials which have unequal expansion and a tight connectionrwill be provided at all times whereas if theconnection was made in the usual manner the greater expansion of the steel part would break. the connection with the part of lesser expansion. In the modification shownin; Figure 3 the radiator section 1 is connected with the fire pot section'2 by a split ring 5 which has a flange 6-which engages a groove 7 formed in the upper end of thefire pot section, This ring being split will. permit expansion and contraction of the part' 1 so that a tight conmotion is provided between the radiator and firepot.
By making the radiator of steel it will radiate heat faster than if it was Inadeof cast iron or similar material and by making the fire pot section of cast iron or other suit-- able material there is'no danger of the same being burntout by the intense heat generated therein. 1
Figure 4 shows the invention applied to a different form of furnace wherein the radiator section 8 is movably attached to the fire pot section 9 by the pairs of crossed links 10 and by the conical part 11 on the radiator section telescoping the conical part 12 on the fire pot section. Thus the part 8 can adjust itself on the part 9 under the expansive action of the heat on the conical part 11.
Figure 6 shows the radiator section 8 as provided with a flaring lower end 13 which engages a flange 14 formed on the fire pot section 9 so that the radiator section can adjust itself on the firepot section while it is expanding and contracting without breaking the joint between the two sections. A ring 15 formed of sections of either steel or cast iron is carried by the part 8 and rests upon the flange of the part 9.
Figure 7 shows a slightly different form in which the radiator section 8" is of cylindrical shape and engages the flaring upper end of the fire pot section 9". A split ring 15 of steel or cast iron is connected with the part 8" and engages the part 9".
Figure 8 shows a double row of plates 16 of cast iron or the like attached to a casing 17 of steel, these plates being of square formation while Figure 9 shows'a singlev row of plates 16 attached to a casing 17, these plates having wedge-shaped upper ends, as at 18, and their lower parts being split, as at 19. The bottom row of plates shown in Figure 8 and the plates shown in Figure 9 are formed with tongues 20, if desired, so that they may engage a groove in the fire pot section, as shown in Figure 3. This arrangement of parts will permit expansion of the jacket without interference on the parts of the plates while the plates will act as a protective means for the jacket.
- Figures 11 and 12 show a fire pot section formed of a jacket 21 of steel or the like and having a lining consisting of bars 22 of cast iron or the like, thesebars being provided with the grooves 28 which form air spaces. This arrangement will permit expansion of the fire pot and the substitution of the cast iron bars for the usual fire clay lining and cause the fire pot to radiate a great amount of heat. Figure 12 shows a slightly different form of connection between the radiator or feeder section 24: with the fire pot, this connection consisting of a split ring 25 having a beveled lower edge engaging the flaring upper end of the steel jacket 21 of the fire pot.
While some of the drawings show the invention as being used to connect a radiator section with a fire pot section it will of course be understood that the invention can be used to connect a feeder section with the fire pot section, the general object of the invention being to provide means for making a tight joint between parts of the furnace which are made of metals which have different expansivequalities and to protect the parts formed of steel and similar metal from intense heat by parts formed of cast iron or similar metal without the cast iron parts interfering with the expansion of the steel parts.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination andarrangement of the several parts, provided that such changes fall within the scope of the appended claims.
lVhat I claim is 1. In a furnace, a radiator section formed of steel, a fire pot section formed of material having less expansive properties than the radiator and means for connecting the two together to prevent the greater expansion of the radiator from breaking the connection.
2. In a furnace, a radiator section formed of steel, a fire pot section formed of material having less expansive properties than the radiator and means for connecting the two together to prevent the greater expansion of the radiator from breaking the connection, such means consisting of a part fastened to one of the other parts and movably connected with the second part.
3. In a furnace, a section formed of expansive material and a section formed of non-expansive material, parts on said sections engaging each other and means whereby one of said parts has sliding movement on the other part under the expansive action of the first section.
4c. In a furnace, a section formed of steel, a second section formed of cast iron, the first sectionhaving a part slidably engaging a part of the second section and a sectional ring attached to one part and engaging the other part.
In testimony whereof I affix my signature.
ANDREW HALLUM.
