The opposite in which Fig. 1 is an elevation generally intypical sides of the eye having downward and outward section, showing an assembly within a fine, of slope, the weight of the units 2 supported on the parts embodying my invention; Figs. 2,- Band 4 eye will urge them oppositely as well as downare transverse sections as in the respective planes wardlywith cam action. Thus each unit 2 is 45 22, 3-3, 4-4, of Fig. 1; Fig. 5 is a conventionurged outwardly toward the near wall of the flue alized sectional elevation illustrative of a use of A, its panels 2!; bearing against the flue to act the invention; Fig. 6 is'a view generally similar as; fins extending radially inwardly and longito Fig. 1 but illustrating a modified embodiment tudinally thereof. v v
of the invention; Fig; 7 is a plan view of parts From Fig. 3 it will be apparent that the interen- 5o appearing in Fig. 6; Figs. 8, 9 and 10 are transgaging eye parts of adjacent units I amply serve verse'sections in the respective planes 8'8, 9-9 to mainntain the corresponding pair of units 2 and Ill-l0 of Fig. 6; in Figs. 2 to 4 inclusive and with their panel parts 20!. in rectangularly related- 7 to 10 inclusive the inside flue surface being indiametricalplanes. e I M dicated in broken lines. Preferably the eyes of the units I have equal 55 slope in opposite directions so that the tendency of the units 2 is to maintain the central disposition of the units 1. Also preferably the free end of the wire forming each eye is brought substantially to the center line of the unit I so that the corresponding supported unit 2 cannot catch upon the free end of the unit I but must ride on the cam surface provided by the eye.
As illustrated in Fig. 1, this last described arrangement disposes one unit 2 of each pair lower than the opposite one, as indicated in the upper Y and lower parts of Fig. 1, but this is not of importance. Should it be desired that each pair of units 2 be disposed exactly opposite each other, it will be apparent that they may be positioned upon the linkage of units I with their openings 2b receiving the upper eye parts of the corresponding unit 1 instead of the lower eye parts as the drawings show.
The assembly of units within the flue is made from the top end of the flue, the units 2 being disposed upon the units i as the latter are lowered into the flue, and the units I being hooked to each other as they are lowered into the flue. Obviously in this manner the flue may be equipped with the heat transfer device throughout its length as illustrated in Fig. 5 though the head space above the flue be not more than the length of one of the units. As the assembly is lowered into the flue, and thereafter, the units 2 bear firmly against the flue sides.
Disassembly of the heat transfer parts must be made downwardly. That is, to remove the parts from the flue, the uppermost unit i is detached from its support 6 and lowered, which immediately frees all of the units 2 from the flue sides, permitting lowering of the assembly and in turn permitting removal of the successive lowermost units from the bottom end'of the flue.
It will be apparent that the heat transfer device disclosed somewhat impedes flow through the flue. Such action is desirable since turbulence of the flue gases improves heat transfer between the gases and their confining parts. Thus the eye parts of the units 1 which project slightly into the segmental spaces between the panel parts 2a of the units 2, create turbulence which improves heat transfer from the gases to the panel parts 211. Similarly the spaces between vertically adjacent units 2 assist the scouring heat transferring action.
With reference now to Figs. 6 to 10 of the drawings, a modified form of unit is disclosed, suitable for production by casting and permitting that all of the units employed be identical.
Generally designating one of these units as 3, from the drawings it appears that each as before comprises a pair of panels 30;, longitudinally coextensive and disposed at right angles to each other and joined by a bend. Each has a slot opening 3b slightly offset from its central transverse plane, and a projection 3c thereadjacent and extending in the direction of convergence of the panels 311. The unit is provided with a pair of projections 3d, one adjacent each end and each extending from one of its panels 3a, to assist in heat transfer by creating turbulence. The unit has at one end a hook member 3e and at its opposite end an eye member 3f.
The parts are so proportioned and arranged that a pair of linkages may be made of these units and disposed in parallel relation within the flue A, as indicated in Fig. 6 of the drawings, the
hooks of the units of onelinkage being uppermost and the eyes of the units of the other linkage being uppermost; so that the projection 30 of each unit will enter the opening 32) of the adjacent unit of the other linkage.
Each projection 30 has a sloping face and a face extending substantially transverse of the flue, and for each pair of links the two sloping faces of their projections 30 may interengage in the assembly.
The assembly of the two linkages is made generally as before, from the top of the flue, building onto the linkages as the latter are lowered into the flue, the building up of bothlinkages being simultaneous.
Once the two linkages are so assembled in the flue as indicated in Fig. 6, the right-hand linkage only is secured to be suspended from its upper end. Each link of the left-hand linkage lowers in the flue until its projection 30 engages that of the corresponding link of the right-hand linkage. Upon such engagement the (left-hand) link of the pair is cammed outwardly against the flue side wall, the opposite link being correspondingly,
cammed in the opposite direction against the opposite face of the flue so that the two units of the pair both have tight bearing against the flue, each serving as backing means for the other.
Removal of this form of heat transfer means from the flue may be had either downwardly or upwardly. If removal is to be upward, the lefthand linkage is raised. By such operation the projection 30 of each link of the left-hand linkage, Fig. 6, engages the upper end of the slot 3b of the corresponding right-hand unit, thus freeing both links of each pair from their wedged engagement: within the flue; the left-hand linkage being raised out of the flue as in any linkage of detachable links, and for each unit therein a unit of the right-hand linkage being withdrawn also.
If it is preferred to remove the heat transfer means downwardly, the right-hand linkage is detached from the means by which it was suspended and lowered. This again frees all the units from their expanded positions against the flue, permitting removal of the units from the bottom ends of their linkages.
