Description
March 1952 L. DOLLINGER CHIMNEY AND THE LIKE Filed March 12, 1947 167' FLOOR u/v/r INVENTOR. LMSLOOLUN6A By AO W ATTOAP/Vf) Patented Mar. 11, 1952 UNITED STATES 'ATENT OFFICE 3 Claims.
This invention relates to chimneys as well as to combined smoke flues and heat exchangers.
The conventional brick or stone chimney is very expensive since it requires much heavy foundation structure, large quantities of material and much skilled labor in the construction thereof. The conventional chimney or smoke flue, in addition, wastes considerable heat.
The present invention has for its purpose the production of a chimney which can be quickly constructed by unskilled workmen at relatively small cost.
The main feature of the present invention relates to a prefrabricated sectional chimney or smoke flue which approximates the appearance of a conventional chimney. This smoke flue, when built within the wall structure of the house, serves also as a heat exchanger to extract heat from the flue gases and to conduct this heat into one or more rooms of the house.
The invention will best be understood from the detailed description and claims when taken with the drawings in which:
Fig. 1 is a vertical section of a fragment of the chimney and of the side wall of a house of which it is a part;
Fig. 2 is a cross section of the chimney or smoke flue suitable for outside use, taken on the line 2-2 of Fig. 1;
Fig. 3 i a fragmentary perspective view of this chimney with a part of the outside covering thereof broken away;
Fig. 4 is a fragmentary perspective view of a modified chimney or smoke flue suitable for inside use and provided with openings to discharge heat extracted from the flue gases therein;
Fig. 5 is a diagrammatic view showing how this last-mentioned chimney can be used to discharge heat at various floors of a building; and Figs. 6 and '7 are cross sectional views of other modifications of the invention.
The chimney or smoke flue F when primarily intended for outdoor use is preferably made from four plates such as 5 (Figs. 2 and 3) of fireproof material, such as steel, having flanges 6 projecting outwardly from their side edges at angles greater than 90. The plates are assembled in the form of a rectangular smoke passage with adjacent flanges 6 in contact, the contacting surfaces of the flanges being sealed together such as by welding. A rectangular shell 1 of expanded metal or the like encloses at lea-st three sides of the smoke passage in spaced relation thereto. The fourth side of the mentioned shell which may be left open, faces the side wall 9 of the house 2 except for a bracket I0. to two adjacent flanges 6 and enables the flue to be attached to the side Wall of the house. If desired, the shell can be provided with a covering II of stucco or with a veneer-like layer of thin bricks presenting the appearance of a brick chimney. For ease in erection, the flue F can be made in several sections, one section having a sleeve l2 (Fig. 1) connected thereto to telescope into the end of an adjacent section. The lower section of the flue is provided with a suitable connection into which a smoke pipe l3 can be telescoped.
Where this chimney is erected within the building, registers such as I! (Fig. 5) are provided in the shell I and coverin H to communicate with the several spaces between the inner shell, formed by the plates 5, and the outer shell I. The heat extracted in these spaces, from the smoke flue,
is discharged through the registers I! into the rooms of the building.
In Fig. 4, an inside smoke flue 0r chimney is illustrated. This chimney preferably includes a rectangular inner shell [4 of sheet material defining a smoke passage. A bracket I5 projects outwardly from each of the corners of the shell to support an outer shell [6 in spaced relation to the first shell thereby providing a heat flue which completely surrounds the smoke flue. The outer shell has a register I! therein preferably in each room through which the chimney rises. Thus, if the heating unit or fireplace is in the basement a register can discharge heat at the first and second floors as indicated in Fig. 5. In practice, the outer shell 16 is covered with heat insulating material, such as asbestos, to eliminat fire hazard. It will be understood that the chimney illustrated in Figs. 4 and 5 will be made in sections, as indicated by the broken lines in Fig. 5. In this arrangement also, one section will be provided with a sleeve (not shown but similar to sleeve I2 of Fig. 1) to telescope into an adjacent section.
In the modified form of the invention, illustrated in Fig. 6, the rectangular inner shell I9, is made by folding a single sheet of fireproof material, such as sheet metal, and then sealing the adjacent edges by welding or the like. As herein shown these edges can serve as a flange 20 which extends diagonally outward from the adjacent corner of the shell. The other corners of the shell are provided with diagonally extending brackets 2| of narrow width. These brackets together with flange 20, have attached thereto This bracket is joined an outer shell 22, which can be similar to any of those previously referred to.
In the modification of the invention shown in Fig. 7, the inner shell 24 is preferably made from sheet metal shaped to have a circular cross section or the like. The side edges of the sheet which overlap are welded or otherwise sealed, as indicated at 25. Relatively narrow brackets 26 are secured to the outer surface of the shell to extend outward therefrom. These brackets support an outer sheet 21 of the character previously mentioned.
In accordance with the invention, if the inner shell which defines the smoke passage, becomes leaky, a new sectional shell can be lowered into the original inner shell to act as a liner therefor, defining a new smoke passage. For this reason, the original smoke passage should have suflicient cross sectional area that there will be ade-- quate draft, when a new liner is lowered into the original chimney.
This disclosure is given by way of example only and there can be many variations and modifications thereof, within the scope of the appended claims, without departing from the spirit of the present invention.
What I claim is:
1. A combined chimney and heat exchanger comprising elongated metal plates provided with integral continuous projecting flanges along their.
side edges, means sealing together the surfaces of the flanges of adjacent plates to define a smoke passage and with the flanges projecting outwardly therefrom, and a shell supported on the projecting flanges in spaced relation to said passage, to define heat flues adapted to communicate with rooms to be heated, said shell comprising sheet metal shaped to engage said flanges.
2. A combined chimney and heat exchanger comprising four elongated metal plates, each provided with flanges projecting from each side edge thereof at an angle greater than ninety degrees for substantially the entire length thereof, means joining said plates into a rectangularly-shaped smoke passage with a pair of flanges extending outwardly at each of the resulting corners, the adjacent surfaces of each pair of flanges being in contact witheach other, and fireproof material enclosing at least a portion of said passage in spaced relation thereto, being supported on said flanges to provide a plurality of heat flues, said material having openings therein communicating with certain of said heat flues and adapted to communicate with rooms to be heated.
3. A combined chimney and heat exchanger comprising four elongated metal plates, each provided with flanges projecting from each side edge thereof at an angle greater than ninety degrees for substantially the entire length thereof, means joining said plates into a rectangularly-shaped passage with a pair of flanges extending outwardly at each of the resulting corners, the adjacent surfaces of each pair of flanges being in contact with each other, a sheet of metal encased in masonry and enclosing at least a portion of said passage in spaced relation thereto, being supported on said flanges, said sheet having at least one opening therein communicating with the space between said sheet and one of said plates, and a register mounted in said opening.
