United States Patent O 3,046,976 VENTED WALL FLUE Robert E. Aggscn, Azalea, Greg. (5322 McKenzie Highway, Springfield, Greg), assigner f forty-nine percent to Eddie E. Parker, Glendale, Oreg.

Filed June 26, 1956, Ser. No. 593,953 4 Claims. (Cl. 126-316) This invention relates in general to new and usefull improvements in flue construction, and more specifically to a vent wall flue.

In ordinary iiu'e construction access to the interior of a chimney within a room is obtained by placing in the wall of the room and the wall of the chimney a flue liner. The stove or furnace is then connected to the chimney by terminating `a stove pipe in the flue liner. lIn many instances the iiue liner does not have a proper seal with respect to the chimney so that gases will 'escape between the flue liner and the chimney. Also, it is difficult to obtain the proper seal between the metal smoke pipe and the ceramic flue liner, ceramic material generally being used for the formation of flues. Another problem has been that little provision has been made for the overheating of the smoke pipe `and the subsequent overheating of the wall structure so that iires are often caused by overheated smoke pipes.

It is therefore the primary object of this invention to provide a wall flue which is vented whereby the wall in the vicinity of the flue is not subject to overheating thereby preventing fires due to overheated smoke pipes.

Another object of this invention is to provide an irnproved wall ue which is formed of metallic materials and which is formed in sections whereby shifting of the chimney With respect to the wall of the building will not result in the cracking of the various components of the wall ue so as to permit the escape of gases and the like.

Another object of this invention is to provide animproved wall flue which is so constructed whereby a smoke pipe may be passed entirely therethrough with the smoke pipe having its inner end disposed within the confines of the chimney thus permitting an elective seal between the chimney 'and the smoke pipe.

A further object of this invention is to provide an improved wall flue construction which is adjustable whereby the wall illue may be adjusted to walls of various thicknesses.

Still further object of this invention is to provide an improved wall flue of the vented type, the venting of the wall flue being of such a nature whereby radiated heat from `a smoke pipe passing lthrough the Wall iiue, is

l circulated back into the room in the wall of which the wall ue is mounted.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the laccompanying ldrawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE l is a vertical sectional view taken through an intermediate portion of a chimney and adjoining wall of .a room and shows the general relationship of the wall flue whichis the subject of Athis invention with respect to both the chimney and a smoke pipe passing therethrough;

FIGURE 2 is a fragmentary horizontal sectional View taken through the chimney and the wall in the vicinity of the wall flue and shows further the general relationship between the wall flue, the smoke pipe and the chimney;

FIGURE 3 is an enlarged fragmentary sectional view taken substantially upon the plane indicated by the section line 3 3 of FIGURE 1 and shows the general appearance of the front cover plate of the Wall ilue;

ICC

FIGURE 4 is an enlarged fragmentary horizontal sectional view taken substantial-ly upon the plane indicated by the section line 4-'4 of FIGURE l, only the wall flue and the smoke pipe being shown, the specific Idetails of the wall ue and the connection of the smoke pipe relative thereto being clearly illustrated;

FIGURE 5 is an enlarged fragmentary sectional View taken substantially upon the plane indicated by the section line 5 5 `of FIGURE 2, the View being taken only through the wall ilue and the smoke pipe and shows the flow of air through the Wall flue; and

FIGURE 6 is an enlarged sectional view taken substantially upon the plane indicated by the section line 66 of FIGURE 5 and shows the manner in which a smoke pipe is supported within the wall flue.

Referring now to the drawings in detail, it will be seen that there is illustrated in FIGURES l and 2 a conventional stove chimney arrangement which includes a stove 10 having a smoke pipe 12 connected thereto. G-ases from the smoke pipe 12 exit into a chimney 14 having a draft passage 16 extending vertically therethrough. Extending through a wall of the chimney 14 and opening into the draft passage 16 is an opening 18.

Disposed intermediate the stove 10 and the chimney 14 is a Wall which is referred to in general by the reference numeral 20. The Wall 20 includes a plurality of studs 22 which have secured to the faces thereof remote from the chimney 14 a wall forming material 24. Normally there would be mounted within the opening 18 and carried by the wall 20 a ceramic flue liner which would be sealed with respect to the chimney 14. The smoke pipe 12 would enter into the room end of the flue liner (not shown) and terminate short of the chimney 14. This would permit leakage of gases between the ue liner and the chimney 14. Also, the ue liner is normally supported by the studs 22 or other parts of the wall 2b and When subjected to overheating could possibly cause a re.

Mounted within the wall 2t) and extending between the chimney 14 through the opening 18 is the vented wall iiue which is the subject of this invention, the Wall ue being referred to in general by the reference numeral 26. The wall flue 26, `as is best illustrated in FIGURES 4 and 5, includes an inner sleeve 28 which is preferably circular in cross section. Disposed about that portion of the inner sleeve 28 remote from the chinmey 14 is an outer sleeve which is referred to in general by the reference numeral 30. The outer -sleeve 30, as is best illustrated in FIGURE 6, is preferably square in cross-section. The outer sleeve 30 is formed in sections and includes an inner section 32 which is telescoped over the inner end of an outer section 34. By Iadjusting the

sections

32 and 34 relative to each other, the outer sleeve 3i) maybe adjusted to accommodate walls of various thicknesses.

The inner sleeve 28 is connected to the outer sleeve 36 by means of a front cover plate 36 which is generally square in outline, as is best illustrated in FIGURE 3. Front cover plate 3'6 terminates along its side edges in vertically side flanges 33 which `are secured by means of fasteners 40 in fa'ce-to-face engagement with vertical flanges 42 extending upwardly a-long the outer edges of the outer section 34. The front cover plate 36 is provided with a central opening `44 of -a size to snugly receive the outer end of the inner sleeve 28. If dired, the inner sleeve 28 may beI suitably secured by welding or the like to the front cover plate 36.

The inner section 32 of the outer sleeve 30 terminates in an end wall 46 which in turn has an `opening 48 therethrough bounded by a peripheral flange Sil. The opening 48 is of a size to snugly receive the inner sleeve 2S and outlet opening 62.

Y the l'lange 50 Aforms a suitable support for the inner sleeve 28.

The outer section 34 of the outer sleeve 36 includes a lower depending ange 52 which is disposed in the same plane as the flanges 42. The i'lange 52 extends down below the lower edge of Ithe front cover plate 36 and terminates in a forward and downwardly sloping lip 54.

The outer section 34 also includes an upper ilanger which is disposed coplanar with the flange 52. The flange 56 extends upwardly above the upper edge of the front cover plate 36 and terminates in an upwardly and or- Wardly directed lip `S. It is to be noted that the cover plate 36 is spaced from the lips 54 and 5S thus providing a lower inlet opening ed and an upper outlet opening 62.

In order that air will not pass directly upwardly about the inner sleeve 2S 'from the inlet opening 60 to the outlet opening 62 immediately behind the front cover Vplate 36, there is positioned within the outer sleeve 30 and about the inner sleeve bale 64. The baille 64 is carried bythe `front cover plate 36 Iand is secured to the lower part thereof by suitable fastener 66. The baille 64 is cut to receive the inner sleeve 28 thus causing the ow of air therearound.

In order that a limited quantity of air may also be cirv Voulated within the inner sleeve 2S, the inner sleeve 2'8 is provided with suitable openings 68. These openings 68 are best illustrated in FIGURES 5 and 6.

In order that the inner sleeve 28 may properly support the smoke pipe 12, the extreme end of the inner sleeve 28 terminates in a reduced neck portion '70. The reduced neck portion 70 is intended to become interlockingly engaged with the inner end of the smoke pipe 12 as at 72. Also, Ithe outer `part of the inner sleeve 2S is provided with suitable spacing ribs 74 for engaging an intermediate part of the smoke pipe 12, as is best illustrated in FIGURE 6.

In the proper mounting of the vented wall iiue 26,

the inner sleeve 2S will `beof a length so as to pass into the interior of the chimney 14, as is best illustrated in FIGURES l and 2. The outer sleeve 30 will be `adjusted to ybe of proper length, as is best illustrated in FIGURES 1 and 2 according to the wall thickness. The smoke pipe 12 will be of a length to pass entirely through the inner sleeve 23 and have in relationship with respect thereto as is best illustrated in FIGURES 4 and 5. Thus, the smoke pipe 12 will terminate within the chimney 14 and the escape of gases intermediate the end of the smoke pipe 12 and lthe chimney 14 will be prevented.

Due to convection, relative cool air will enter into the air inlet 6i) and will pass upwardly through the wall ue .26. A majority of the air will pass around the inner Ysleeve 28 and between the inner sleeve 28 and the outer l sleeve 30 so as' to maintain a cool air space between the two. A certain amount of the air will pass into the interior of the inner sleeve 28 and around the smoke pipe 12 so as to reduce the temperature of the smoke pipe 12. This air will exit through .the upper partof the inner sleeve 2S into the outer sleeve Sil and out through the 'Ihus it will be readily apparent that the ilue 26 is suliciently vented so as to prevent overheating. Also, by venting the tlue 26 and removing yfrom Athe smoke pipe 12 a certain amount of the waste heat carried thereby, it will be seen that additional heat is provided yfor the room in which the stove 10 is mounted. This will provide a suitable saving.

While the Wall tine has been specifically illustrated `and described with respect .to an interior wall, it will be readily apparent that the invention is not intended to ,principles of the invention. `Further, since numerous engagement in a chimney opening and an outer sleeve Y for engagement in a wall opening registered with said chimney opening, connecting means mounting said inner sleeve in spaced nested relation Within said outer sleeve, spacing means carried by said inner sleeve for retaining a smoke pipe in spaced nested relation within said inner sleeve, one end portion or" said outer sleeve adapted to project outwardly of a wall openin-g and into a room and. including ya transverse passage means having inlet and outlet openings enabling air Within a room into lwhich said one por-tion projects to circulate through said outer sleeve, transverse passage means in said inner sleeve having inlet and outlet openings enabling air circulating through said outer sleeve to also circulate Ithrough said inner sleeve, baille means in said outer sleeve for etecting a tortuous path of the air circulating therethrough, portions-of said tortuous path extending longitudinally of said outer sleeve.
