UNITED STATES ALBERT H. HEIMBACH, OI 8'1. PAUL MINNEBOTL COMBINED VENTILATING FLUE AND CHIMNEY.

' Application filed August 11,1922. Serial No. 581,044.

To all whom it may concern:

Be it known that I ALBERT H. HEIM- neon, a citizen of the 'il'nited States residing at St. Paul, in the county of Iiamsey 6 and State of Minnesota, have invented certain new and useful Improvements in Combined Ventilating Flues and Chimneys; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in chimneys and, more particularly, 1 to chimneys bu t up of tiles or mctions supported, the one upon the other, and having one or more smoke flues and a multipllcity of ventilating flues formed therein for carrying off the foul air from the differcut rooms of a dwelling or other building and fumes from gas stoves, gas logs and the like, and the odor and smoke from cooking stoves.

To the above end generally stated, the in- 26 vention consists of the novel devices and combination of devices hereinafter described and defined in the claims.

In the accompan ing drawings, which illustrate the invention, like characters indicate like arts throughout the several views.

Referring to the drawings Fig. 1 is a sectional view of a dwelling having a chimney built in accordance with my invention;

Fig. 2 is a fragmentary perspective view of one of the chimney tiles; 7

Fig. 3 is a vertical central section taken through the upper portion of the chimney;

Fig. 4 is a perspective view of four of t e uppermost chimney tiles separated, the one from the other;

Fig. 5 is a view partly in end elevation and partly in horizontal section taken on the line 5-5 of Fig. 1 on an enlarged scale; and

Fig. 6 is a perspective view of one of the coupling sleeves.

The numeral 10 indicates a dwelling hav ing a basement 11, a first floor 12, and a second floor 13. Said first and secondfloors have partitions dividing the same into rooms, in each of which is a. radiator 14. In

I the basement 11, is a steam or hot water heater 15 having a smoke pipe 16, and in one of the rooms on the first floor is a 000k mg range 17 havinga ventilating pipe 18.

A chimney constructed in accordance wlth my lnvention is carried on a footing 19 in the basement 11 and extends through the dwelling and above the roof 20 thereof. ThlS chimney consists of a plurality of tiles or sections of burnt clay or other material supported, the one upon the other, and each having a rectangular inner shell 21 and a rectangular outer shell 22 spaced, the one from the other, and joined by longitudinal partitlons 23. These partitions 23 are formed by continuing the sides of the inner shell 21 and divides the space between the two shells. 21 and 22 into four rectangular secondary corner flues 24 and four rectangular secondary intermediate flues 26.

The inner shell 21 affords a central main smoke flue 27 that is completely surrounded by the flues 24 and 26. If two smoke flues are required, a vertical partition may be. formed within the inner shell 21, and in which case, said inner shell 21 will have to have a ater area in cross-section. It will be note that the ends of the outer shell 22 terminate short of the ends of the inner shell 21 and partitions 23, and that the open joints between the ends of adjacent outer shells are pointed up with cement 28.

Rectangular coupling sleeves 29 of the same material. as the chimney tiles, or any other suitable material, are provided for connecting the abutting ends of said chinmey tiles, and lock the same against angular turning movement, the one upon the other, and hold the same with the sections of the flues aligned. These sleeves 29 are loosely telescoped into rabbeted seats 30 in the ends of the inner walls of the inner shell 21 and their inner faces are flush with the inner faces of the central main flue 27. Each outer shell 22 has formed therein a plurality of the lowermost chimney tiles and which tile rests directly on the footing 19, are ahgned holes which afi'ord a clean-out opening 34 their outer shells 22 scored or otherwise marked to represent brick, and the uppermostof said tiles has formed, with its upper end portion, a cap 36 into which all of the fines 24 and 26 open and through which the central main flue 27 completely extends. This cap 36 is completely closed to the atmosphere, except for a plurality of horizontally spaced holes 37 in its outer walls. The top of the cap 36 is downwardly inclined from the central main flue 27 to shed water and said cap has a greater cross-see,

tion than the chimney proper and overhangs the outer shell 22.

Certain of the holes 31 and 32 open directly into the room through whlch the chimney passes and ventilating pipes in the walls or under the floors Wlll lead from rooms, through which the chimney does not pass, and extend into certain other of the holes 31 and 32. As shown in Fig. 1, the

menses ventilating stove pipe 18 extends into the hole 32 in one of the fiues 26. I

It is, of course, understood that the holes 31 and 32, not used for ventilating and smoke pipe purposes, will be closed by the plaster or in any other suitable way, or, if necessary, holes, not shown, may be formed in the shells 21 and 22 for ventilating purposes and to receive smoke pipes.

What I claim is:-

1. A chimney tile consisting of spaced inner and outer rectangular shells, the former of which affords a central main flue, the sides of said inner shell being extended to the walls of the outer shell to .form rectangular corner and intermediate fines that are entirely separate the one from the other, certain of said outer shells having holes that open directly into the corner and interme diate fines.

2. The structure defined in claim 1 in which one end of the inner shell at its extended sides extend outward of the respective end of the outer shell and terminates short of the other end thereof, and independent coupling sleeves telescoped into rabbeted seats in the abutting ends of the inner shells. 1

3. A chimney flue comprising a plurality of blocks supported the one upon the other, and independent coupling sleeves telescoped into rabbeted seats in the ends of abutting blocks.

In testimony whereof I afiix my signature.

ALBERT H. HEIMBACH.
