1 Claim.
My invention relates to hot air discharging unit, an object of the invention being to providemeans whereby over-heated air'in the vicinity of a smoke pipe may be discharged through the adjacent ceiling and/or roof or through an adjacent Wall.
A more specific object is to provide a hot air discharging unit assuming the form of a collar designed to encircle the portion of a hot air pipe which passes through a wall, or a ceiling and/r roof so that the hot air may either be conducted to the open air, or into a roof loft or attic. 1
Most, particularly, the unit herein illustrated has for its objects the conduction pastan insulated and vertically disposed portion of smoke pipe, over-heated air from the area in the vicinity of the smoke pipe elbow, through the ceiling and into the roof loft or attic where it assists in keeping the layer of insulation, dry so reducing the possibility of spontaneous: combustion and preventing discolouratio-n of the ceiling around the smoke pipe. 7
A further object is to provide a device of the character herewithin described having an outwardly and downwardly, annularly bevelled and elbow 1 provided with cleanout cover 6, and via this elbow, with the horizontal smoke pipe 9.
fThe smoke pipe I and jacket 2 extend through ceiling I0 and roof I I, and in the plane (by which expression I mean between the upper and lower horizontal bounding planes) of the ceiling I encircle the smoke pipe I outside the-jacket 2 with the multi-apertured hotair discharging unit collectively enumerated I I which I will now describe.
The said unit comprises a collar I2, the upper and lower ends whereof are formed into the anapertured upper shoulder over which material such a insulating particles will gravitate away from the hot smoke pipe rather than lie thereon with the possible danger of starting a fire.
With the above objects in view, and such other objects as may be implicit in the disclosure herefollowing, my invention consists of the following arrangement and construction of parts, reference being had to the accompanying drawing which illustrates the same in vertical cross-section and in combination withhorizontally disposed and vertically disposed pieces of smoke pipe and a connecting elbow.
It is to beunderstood at the'outset that the invention herein described and claimed is for use predominantly in association with ,a smoke pipe such as that illustrated, wherein the vertical portion I is provided with the spaced insulating jacket 2., The space between smoke pipe I and jacket 2 is designated by the numeral 3 and it will be seen that the smoke pipe I is held centred with respect to the jacket 2 by means of the cap 4 at the top, and the annular flange 5 at the bottom.
The aforesaid smoke pipe I is slidable endwise by virtue of its aforesaid relationship with the parts 5 and 6 by which it is to be understood the smoke pipe is only frictionally in contact, and it will be seen that the lower end 6 of my smoke pipe is in communication with the conventional structure.
nular shoulders or-flanges I3 and I4 each having a series of spaced apertures I5 and I6 therein. 7
As will be observed, the material of my collar is predominantly in spaced relationship to smoke pipe I, only the upper and lower annular perimeters I1 and? being in contact with the outer shell orlining is of jacket 2, and in the context it is to be understood I use the word smoke pipe and jacket synonymously as in certain claims appended hereto with the explanation that in certain instances I might employ a unit such as herein described in association with an uninsulated smoke pipe. v
The shoulder I3 is crimped between the apertures I5 while the shoulder I i constructed to theconfiguration plainly illustrated in cross-section, is provided with the projecting flange portion 20 V which provides a covering for the aperture made in the ceiling to accommodate my pipe, jacket and collar. Q v
From all the foregoing it will be recognised that I have. provided a means whereby overheated air may be discharged into an attic 2 I, and
it is to be understood that the airaround or in the region of the uninsulated elbow "I and the adjacent part of the'horizontal smoke pipe 9, often becomes very hot due to the change in direction which the products ofv combustion have v to make at the aforesaid elbow; The overheating of these-elbows transmitted to the surrounding air accordingly result. very frequently in discolouration of the ceiling surface around the vertical portion of the smoke pipe, but such discolouration is entirely avoided by the aforesaid Obviously, I may if desired, lengthen my collar I'l so that the same embraces the smoke pipe or the insulating jacket thereof throughout that,
portion thereof which proceeds through the attic 2| and in this way excess heat may be carried out to the atmosphere. This, however, in most cases is unnecessary, since it is to be understood that the hot air carried off through the unit as I have described it into the attic 2| is not apparently widely difierent embodiments of this invention may be made within the scope of the accompanying claim without departing from the spirit and scope of the same it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as justice dictates.
What I claim as my invention is: In combination with a smoke pipe when extending through a ceiling, a, cylindrical collar spaced from and concentrically surrounding said pipe at its locus of intersection with said ceiling, said collar being of a length sufficient to extend from said ceiling to at least the horizontal plane occupied by the upper edges of the conventional ceiling joists, an upper, multi-apertured flange extending inwardly and upwardly from the upper edge of said collar to said smoke pipe, the inner and outer perimetrical edges of said flange engaging the adjacent pipe and the upper edge of said collar respectively, and a lower, continuous, annular, multi-apertured flange secured to the 7 lower edge of said collar, said lower flange extending downwardly and inwardly to said smoke pipe, the outer perimetrical edge of said lower flange extending beyond said collar and overlying the surrounding ceiling-hole-edge.
