5 cracking of a chimney enclosed flue.

Another object of the invention is to provide a ventilating arrangement for a building structure.

The third object of the invention is to provide a system of ventilation, whereby moisture and the like normally present in the basement or cellar of a building structure is removed.

The chief feature of the invention consists in the provision of certain arrangements in the building structure, whereby each of the aforesaid objects is accomplished.

Other features of the invention will appear more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims:

In the drawing, Fig. 1 is a central sectional view through a chimney enclosed flue and a building structure included in a part of the building structure, the same being represented as of a single floor type and provided with a basement or cellar.

Fig. 2 is a transverse sectional View of a chimney enclosed flue, the ventilating passage therebetween and the inlets to said passage.

In the drawing 10 indicates a cellar or basement floor, 11 a conventional heating system, such as a furnace, having the smoke pipe 12. The latter communicates with the flue 13 near its lower end. The upper end 14 extends above the structure and'herein is shown terminating above the top 15 of the chimney 16. The chimney is shown of conventional construction, such as brick work. The flue may be of conventional structure and in the present form of the invention is shown of heavy metal pipe, although it may be of inter-connected tiles. The chimney encloses the flue 13 and is spaced therefrom forming a ventilating and cooling channel therebetween, said channel being indicated by the numeral 17.

In the building structure, 18 indicates the ceiling of the cellar and the first floor of the said structure. 19 indicates the plaster, 20 the lathing and 21 the ceiling structure of the first floor. If a one-story structure is provided, 22 indicates conventionally the roofing thereof. If additional floors are included in the structure, they would be superposed thereon, while the roofing would be mounted on the upper ceiling or rafters if a peak roof were employed.

The projecting upper end of the flue 13 is herein shown supporting a hood 23 in spaced relation above the end 15 of the chimney. Herein the top of the chimney is provided with a complementary structure 24. forming with'the hood a discharge passage or outlet 25 of peripheral char- 5 actor and downwardly and outwardly pitched and communicating at its interior with the ohan nel 17.

Adjacent the ceiling or the roof of each floor, there is provided an inlet passage 26 to each room 10 or to the same room. 'Each inlet passage 26 is provided with a plurality of baffles 27 arranged in offset and staggered relation. The inlet end of each of the inlet passages may be provided with a register construction 28, whereby the de- 5 gree of air removed may be regulated.

The system normally operates as follows: The flue 13 is always hot when there is a fire in the furnace 10 or equivalent heating system. Air in thebuilding structure is hottest at the top 20 of the room and this heated air passes out through the registers into the inlet passage 26 and through the bailie arrangement 27 and discharges into the enveloping channel 17. The resultant action, therefore, is that the rising air column 25 not only discharges through the outlet passage 25 but simultaneously therewith maintains the brick work 16 in a relatively cooled condition and the air rising through the channel conveys the heat from the flue away from the same and with- 30 out transmitting it to any appreciable degree to the brick work. In the ordinary flue and chimney construction, the brick work not only envelopes the flue but in addition thereto, is in direct contact with the flue so that the heat of 35 the flue and the gases therein are transmitted to the brick work resulting in the cracking of the brick work, which structural failure invariably causes a similar structural failure in the flue since the brick work is usually cemented to the flue.

The present invention, therefore, reduces the fire risk due to defective chimneys and flues to a minimum.

While the invention illustrated herein is constructed of brick and metal, it will be evident that 45 the outer portion of the chimney, shown as brick in Fig. 1, could be made of metal and the inner portion or flue could be made of interlocking flue tile without departing from the broader phases of the invention and both may be made of tile 50 or brick or both may be made of metal.

The discharge of'the air from the rooms of the structure to the channel 17 also insures a better air supply in the structure.

If and when desired, there may be provided at 55 the base of the channel 17 a power driven device for facilitating the discharge of air through the channel. Herein there is conventionally illustrated the fan 29 driven by a motor 30.

To prevent condensation upon the cellar walls since, as a general rule they are cooler than the air and particularly during the late spring and early fall, the chimney is provided with additional inlet passages 31 provided with a baffle arrangement 32 and, if desired each is provided with a register construction 3.

The air in the basement or cellar is sucked into the channel 17 by the fan and thus the air is circulated in the cellar and takes .up the moisture upon the walls that would normally condense thereon and the vapor laden air is discharged by the channel 17.

One form of the invention has been here-in illustrated and described in considerable detail. It is to be understood that the same is merely for the purpose of illustration and various modifications thereof will readily suggest themselves to those skilled in the art to which this invention relates, and it is to be understood that such modifications are all considered to be within the broad purview of this invention, reference being had to the appended claims.

The invention claimed is:

1. In a fire protection heating and ventilating system for a building, the combination of a vertical flue arranged for connection at its lower end to the smoke pipe of a furnace and discharging to the atmosphere above the building, a chimney in spaced and enveloping relation to said flue and forming a channel therebetween and completely enveloping the flue, said chimney extending at its upper end above the building and terminating below the top of the flue and terminating at its lower end below the bottom of the fiue, a passage near the room ceiling of each floor level and communicating at one end with the channel for foul and heated air discharge from the room, and means associated with each passage for controlling the discharge therethrough to the channel, the top of said channel constituting the sole outlet therefor, an auxiliary passage connection to the channel near the bottom thereof, and power operable means in the bottom of said channel for drawing airthrough the auxiliary passage and inducing forced passage of air through the channel to increase the cooling effect upon said flue suction upon the room passage to increase air circulation through the room.

2.1m a fire protection heating and ventilating system for a building, the combination of a vertical flue arranged for connection at its lower end to the smoke pipe of a furnace and discharging to the atmosphere above the building, a chimneyin spaced and enveloping relation to said flue and forming a channel therebetween and completely enveloping the flue,'said chimney extending at its upper end above the building and terminating below the topcof the flue and terminating at its lower end below the bottom of the flue, a passage near the room ceiling of each floor level and communicating at one end with the channel for foul and heated air discharge from'the room, bafile means in each passage and a register means associated with the room end of each passage, the top of said channel constituting the sole outlet for the channel, additional passage means connected to said channel near the bottom thereof, and power operable means for drawing air through the auxiliary passage and inducing forced passage of air through the channel to increase the cooling effect of said flue and suction upon' the room passage to increase air circulation in the room.
