BY Gl de .41
A TTORNEY Fatented i9, 1%35 UNITED STATES PATENT orrlca;
6 Claims. (cl. 257-262) My invention relates toflues for use in steam boilers, water heaters, condensers, refrigerators,
and other devices, in which-there is employed mitting the partition'to be withdrawn.
gaseous or other fluids of different temperatures 5 inside and outside of the flues, and it is required to secure a rapid and eflioient transmission of heat through the walls of the flue from the hotter of the two fluids to the cooler. 1, The purposes of my invention are to increase 10 the efliciency of operation of such flues by forcing the fluid within the flue intocontactwith the surface otthe flue so as to secure the most rapid and complete possible exchange of heat between two fluids. I have illustrated and described my 16 device as applied to an ordinary household waterheater, but it is evident that my improved flues may be employed in any form of device involving suchan exchange of heat as is above described without departing from my invention.
I attain these purposes by the means shown in the-accompanying drawing, in which Figure 1 is a vertical section drawn on the line 1--1 of Figure 3. Figure 2 is an elevation of a water heater embodying my device, a part of the outside wall as of the heater being broken away to show the flue inside, the view being taken at an angle of 90 to Figure 1, or on a normal to theline 1-4 of Figure 3. Figure is a cross-section on the line 33 of Figure 1 and Figure 4 is a plan view of the so upper extremity of the tube as will be more fullyexplained hereafter. 4
Referring more particularly to the drawing. 1 is the outer tank or a water heater 0. any approved construction. It may be of anysize or form that 85 may be desired and may be usedfor the heating or. cooling of other fluids than water if desiredr without departing from my invention. Indeed, the heater itself-forms no part of my invention, which is confined to theflue.
2 is the main body of the preferably formed initially as a plaincylindrical flue but is provided with a seriesof indentations" 3, arranged in alternation on diametrically opposite sides of the flue.- Near the upper extremiil ity the flue 2 is welded, ,or tightly secured in any other suitable manner, into the top 4 of the heater and at the lower extremity into the bottom 5, so as to form water tightconnections atboth extremiso Avertical flat partition is'mounted centrally in the flue and retainedin position by a cross member 7. The member 7 has its e ties 12 removably connected to the flue 2 and is provided with a. U shaped curve 8-so that if it is desired to'remove the partition 8, the curve 8 may be comflue itself, which is pressed with pliers, or in other suitablemanner, and so released from the walls of the flue, perr The partition 6 is constructed somewhat narrower than the internal diameter of the flue 2 so 5 as to permit a completezcireulationof the gases around it as shownby the arrows '9 in Figure 1, and as will be more fully explained hereafter. J
The indentations 3 are of sucha depth as to leave a small space 10 to permit the passage of 10 gases between the indentation and partition. The lower extremity of the partition 6 is furnished with a suitable means 11 to maintain it in its cen- Y tral position and preferably terminates a short distance above the lower extremity 'of the flue as 15 shown in Figure 1. This arrangement serves to somewhat steady and equalize the gases entering the flue from the combustion chamber, and insure an equal supply of said gases toeach side of the partition 6. 'I'hisequality is furtherpromoted 2o 4 by making the partition somewhat narrower than theintemal diameter of the flue. While, however, the partition 6 is required to secure the highest degree of efliciency of operation, the flue itself as constructed with the use of the indentations 3- is highly efficient in operation without the'.parti-' tion, for as shown by the arrows the upward flowing gases are continually forced into close contact with the indentations in the flue and as they pass around the curve the alternating indenta-v so tions again forces them not only into contact with itself but into contact with the opposite side of the flue. It will also be readily 'seen that'this effect is, greatly increased by the-use of the partition which also operates as a retardingv means to prevent the too rapid flow of, the gases through the flue. J
,I claim as my invention and desire to'cover by Letters -Patent:' 1. In a deviceof the character described, a flue 40 provided with a plurality of inwardly extending indentations alternately positioned along its opposits sides, and having a longitudinally extending partition mounted within it.
provided with a plurality oi. inwardly'extending indentations alternately positioned along its op posite sides, and having a longitudinally extend-- ing partition removably mounted within it.
a, In a device of the character described,-a flue so I provided wlth.aplurality of inwardly extending indentations alternately positioned along its opposite sides, and having a longitudinally extend- W ing partition removably mounted approximately in the center of said flue.
2. In a device or the character described, a flue 46, 1
indentations alternately positioned along its opposite sides, and having a longitudinally extending partition removably mounted approximately in the center 0! said flue near to, but not in contact with, said indentations. I
6. In a device of the character described, a flue provided with aplurality oi inwardly extending indentations along its sides, and having a longitudinally extending partition mounted within it.
