F UIFR N'AG'E Specification of Letters Patent.

Patented Aug. 21, 1906 Application filed September 19.1905. Serial No. 279,070.

To (L/1L whom it may concern.

Bo it known that I, EDWIN E. Jonas, a citizen of the United States, and a resident of Clovtland, in the county of Pawnce and Trrritory of Oklahoma, have invented a new and Improvid F urnaco, of which the followingris a full, clear, and exact dr scription.

. he rssrntial objrct of my invention is to provide a furnace by means of which the gasrs of combustion will bc effectually consumed, and in this manner the best possible heating efli ct obtained. In securing this end I provide a flue passing from or 13011111111- nicating with the fire-box, which fine is preferably though not nr or. ssarily a downtake-flue and which has a certain peculiar formation, causing the heavirr and lighter bodies of thr: gases of combustion to take movement along crossing or interfering lines, thus bringing about rcpcated intimate association between the colder and hottor gases and causing tho combustible in the colder gases which would otherwise escape through the stack of' the furnace to be ignited and consumed by the heat of the hotter gases. in this manner as the gases pass from the fire-box all of the combustible in the gases is burned and the best thermal (fi'lCiGIlCY is attained.

The invention involves various other features of major or minor importance, all of which will be fully set forth hereinafter, and particularly pointed out in the claims.

Reference is had to the accompanying drawings, which illustrate, as an example, one manner of embodying my invention in a stationary boil rfurnacc, in which drawings Figure 1 is a sectional view of the invention on the irregular linc l l of Fig. 2. Fig. 2 is a sectional plan on the line 2 2 of Fig. l and Figs. 3, 4, 5, and 6 are cross-sections of the flue, respectively, at the points marked 3 3, 4 4, 5 5, and 6 6in Fig. 2.

According to the arrangement shown in Fig. 1, 10 indicates the shell of the boiler, 11 the fire-box, and 12 the downtakc-flue passing from the fire-box through. the boilrr-shcll to the smoke-box 14. From the smoke-box 14 the return-flucs i5 carry the gasrs into the stack or chimney 16, which passes from the As shown in Fig. 2, the flue 12 is curved laterally, giving the flue an undulatory or sinuous form. T he flue has the shape of a double compound curve. At the point 12 (see Figs. 2 and 3) the flue is depended, and at the correspond ingl' opposite point 12 the fine is relatively shal ow. At the point 12 the flue is deepened and'mad e relatively shallow at the point 12. (Ste Figs. 2 and .4.) At the point 12 the flue is (.eepened, and at the point 12 it is relatively shallow. (Soc Figs. 2 and 5.) At the point 12' the flue terminates in the smokebox 14 with ap roximatuly a uniform depth. (See Figs. 2 ant f 6.)

Referring to Figs. 2 to 6 of the drawings, it will be seen that the elevated portionslLiZ and 12 and 12 occur at opposite sides of; the flue, while the shallow or depressed portions 12* and 12 and l2 also occur at opposite sides and are arranged oppositely with'rc- 7o spect to the deep or elevated portions of the fluc. The result of this construction is that as the gases pass from the fire-box the hottest gases will enter the fine at the elevated pore, tion 12, and these gases approach the dcpressed portions 12 and 12 said gases will cross over to tho oppositc side of the flue into the elevated portions 12 and 12 At the same time the colder gases will enter the flue and take a position at the depressed or shallow part 12 of the flue and in traversing the flue will encounter the hot gases crossing from one point to the other, the colder gases being forced across the flue to the depressed ortion 12 and 12 It will be seen, thcrcore, that the peculiar construction which I employ separates the hotter and colder gases into two distinct currcnts which are forced to crossor intersect each other, thus bringing about a thorough intermingling of the hot and cold gases and causing the combustible in the colder portions of thc gas to be ignited and burn completely bcforc the gases pass from tho furnace. As the gases cross each other and mingle in the part of the fluc indi- 5 cated by the characters 12", 12 12, and 12 the mingled and burning ascs pass on in a body and are discharged rom the end 12 The sinuous or undulatoly form of the side walls of the flue also greatly enhances the T00 abovedcscribcd action. it is pointed. out that the line may be given any desired number of turns, and it is also pointed out that the elevated and depressed portions in the flue may be multiplicd at will, causing the x05 hotter and colder gascs to scparatc after their first intersection and again to iutcrscct or min 1e, so as to repeat the opcration any num er of times desired.

Having thus described the preferred form of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A furnace having means for causing the hotter and colder gases of combustion to move along intersecting or crossing courses, whereby to bring about an effectual mingling of said gases, for the purpose specified.

2. A furnace having a flue for the gases of combustion, said flue having at two points along its len th relatively high and low portions locate opposite each other, and the high and low portions at one point being respectively at the sides of the flue opposite the sides having the high and low portions at the other point, whereby to cause the hotter and colder gases of combustion to move along intersectin courses and bring about effectual commin ing of said gases.

3. A urnace having a flue for the gases of so combustion, said flue having an essentially flat bottom, and having at diflerent points along its len th relatively high and low top walls locate opposite each other, and the high and low top walls at one point being respectively at the sides of the flue opposite t 1e sides having the hi h and low top walls at the other point, where iiy to cause the hotter and colder gases of combustion to move along intersecting courses and bring about 3c effectual commingling of said ases.

4. A furnace having means or causing the hotter and colder gases of combustion to move along intersecting or crossing non-ver tical courses, whereby to brin about an effectual mingling of said gases, or the purpose specified.

5. furnace having a flue for the gases of combustion, said flue having an essentially flat bottom and curving in essentially the lane of said bottom, and the flue having at ifferent points along its length relatively hi h and low walls located opposite each ot er, the high and low top Walls at one point being relatively at the sides of the flue opposite the sides having the high and low top 5 walls at the other point, whereby to cause the hotter and colder gases of combustion to move along intersecting courses and bring about effectual mingling of the gases.

6. A furnace having a non-vertical flue for go the gases of combustion, said flue having an essentially flat bottom and curving in essen tially the plane of said bottom, and the flue having at different points along its length relatively high and low walls located opposite each other, the high and low top walls at one point being relatively at the sides of the flue opposite the sides having the high and low top walls at the other point, whereby to cause the hotter and colder gases of 6c combustion to move along intersecting courses and bring about effectual mingling of the gases.

7. A furnace having means for causing the hotter and colder gases of combustion. each to 6 5 move alon curving non-vertical lines or courses, which lines or courses intersect each other to bring about eflcctual mingling of said gases, for the purpose specified.

8. A furnace having means for causing the hotter and colder gases of combustion each to move along curving lines or courses, said lines or courses intersecting each other to bring about an eifectual mingling of said gases, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWIN E. JONES.
