UNITED STATES PATENT OFFICE Application February 10, 1936,*Serial No. 63,120 In Switzerland February 16, 1935 7 Claims.
In the building of a smoke chimney it is a matter of course to arrange matters'so that no amount of overheating of the same should tend to distort it, but this ideal is not realized in general practice. For example, a chimney being built in as an integral part of the building fabric, the force of any heating which would tend to cause a change in the'formv of the chimney flue is resisted due to its built in and stationary char- 10 acter, and cracks and other deleterious and even dangerous conditions arise.
The object of the present invention is a form of chimney in which, whilst the smoke conduit is perfectly supported, it will be free to give l5 to any distorting influences due to heating, without effect on the efficiency of the chimney.
For the attainment of the object stated a chimney is formed of an outer casing of the required length and an inner smoke conduit of the required length, the latter being supported verti cally on the inner face of the outer casing in such a manner that any movement of the smoke conduit such as a lengthening or expansion of the same under heat is freely permitted, the smoke conduit simplyrisingfromitssupports; subsequent cooling'Y with subsequent contraction causing the conduit to come again upon such supports.
For the attainment of the third named ob- Ject the outer casing and the smoke conduit may very suitably and practically be built up of a plurality of units, each unit consisting of a length of outer casing and a length of smoke conduit, with the required supports between them. As the number of units required may be previously pre-V pared it is thus only necessary to fit one upon the other until the desired height is attained,
a very rapid and time-saving method.
The drawing annexed illustrates 'a very convenient and practical method of carrying the invention into effect, and will now be described. In this drawing Figure l is a cross section taken on the line x-x of Figure 2; Figure 2 is a plan of a chimney unit; and Figure 3 is a. View similar to that of Figure l but showing the effect of heat upon the smoke conduit and its position when expanded under such heat effect.
Referring to the figures of the drawing, two complete units of the chimney are shown and part of a third, it being understood that further 50 units built up with these to the desired number to form the complete chimney are merely repetitions of such units. Each unit comprises an outer casing 4 and this casing may be of any material suitable for the purpose, for example moulded 55 fireclay or rebrick, concrete or the like. Upon (Cl. 'l2-92) the inner face of this outer casing are moulded formed or fitted in any manner bearer supports 5. The innersmoke conduit of each unit is seen at 6, and this is formed of any fireproof mate rial and has moulded, formed or fitted thereon the ribsV or projections l. These latter, as will be clearly seen in Figure l, normally rest upon the bearer supports 5, and the relation of these bearer supports and the smoke conduit 6 is such that a guide path is formed for the latter as shown, with sufficient lateral play. The abutting ends of the smoke conduits may be grooved or fluted as seen in the plan Figure 2 at 8, and any desired form of fireproof packing 9 may be employed as shown in Figure 1 inthese grooves or flutes.
The required number of units being preparedthe necessary dimensions in relation to the surrounding part of the building fabric having been observed-these units are taken and built one o upon the other, the contacting edges of the outer casings 4 being joined by any suitable means, such as by cementing. As each outer casing is placed in position the adjoining edges of the smoke conduits 6 are joined and fitted together, 5 the assembly, with relative positions of the bearer supports 5 and the ribs 'l being as seen in Figure 1.
On the smoke conduit as a whole beginning to expand under the influence of heat, the various sections thereof above the lowermost begin to rise and the ribs 'l of the smoke conduit sections 6 leave the bearer supports 5 freely, whilst being guided and supported laterally in their path of movement. This path is limited laterally and at no time can the smoke conduit sections 6 come into contact with the outer casing 4. The annular space I0 left between the parts is Valuable as a heat insulating means, and air in such space, heated by conduction forming the outer surface of the smoke conduit sections, passes freely up to the chimney outlet.
In the form of unit shown the bearer supports 5 on the outer casing 4 of one unit receive and support the ribs 'l of the smoke conduit 6 of the unit above it. This construction is preferred, inasmuch as lateral guiding with limitation of lateral movement of any smoke conduit section is controlled by two sets of the bearer supports. I do not conne myself to this particular relative construction, however.
It will be understood that the forms of supporting means for the smoke conduit Within the outer casing may be varied Whilst still permitting the free movement of such conduit which is the purpose of the invention. Whilst the preparation of the units as described permits of rapid building in of the chimney, there may be instances where a single outer casing in a continuous length and composed or brick or stone or other material is preferred. In such a case the bearer supports may be suitably fitted at the desired intervals as the building of the outer casing proceeds. Also, especially in the case of short chimneys, one suiciently long length of smoke conduit, with ribs l' may be sufficient.
The outer casing i and the smoke conduit S of each unit are shown in the drawing as rectangular. They may however be of other forms, for example circular.
I claim:-
1. A chimney consisting of an outer casing having a smoke conduit within it and separate therefrom, and vertical supports within the outer casing for the smoke conduit which supports permit and guide movement of the said conduit in relation to the outer casing.
2. A chimney consisting of an outer casing having a smoke conduit within it such conduit having free movement relative to the outer casing, bearer supports upon the inner wall of such outer casing, and ribs upon the outer face of the smoke conduit, such ribs normally resting upon the bearer supports to arise therefrom on expansion of the conduit.
3. A chimney consisting of a plurality of units each of which consists of an outer casing element and an inner smoke conduit element, vertical supports within the outer casing for each smoke conduit element which supports permit movement of the same in relation to an outer casing element,
the various units being built upon each other and the assembled outer casing elements and smoke conduit elements forming a complete chimney length.
4. A chimney consisting of a plurality of units each of which consists of an louter casing element and an inner smoke conduit element, bearer supports upon the inner face of the outer casing element of each unit to receive and support vertically ribs upon an inner smoke conduit element, the various units being built upon each other and the assembled outer casing elements and smoke conduit elements forming a complete chimney length.
5. For use in the construction of a chimney a unit comprising an outer casing, a smoke conduit section, and vertical supports between the outer casing and the smoke conduit section which supports permit free movement of the said conduit section in relation to the outer casing.
6. For use in the construction of a chimney a plurality of units each of which consists'of an outer casing, bearer supports upon the inner face or" such casing, a smoke conduit within each cuter casing, and ribs upon each smoke conduit which ribs are adapted to rest upon and be supported by the bearer supports of a further and similar unit below it when the chimney is assembled.
7. For use in the construction of a chimney a plurality of units each of which consists of an outer casing and an inner smoke conduit, and vertically supporting means between the inner face of an outer casing and the smoke conduit associated with the outer casing next in series above the rst mentioned outer casing.
