#PECIFICATION forming part of Letters Patent N0. 761,894, dated June '7, 1904.
Application filed November 21, 1908. Serial No. 182,126. (No model.)
To all whom it may concern:
Be it known that I, JOHN LORENZ, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chimneys, of which the following is a full, clear, and exact description, such as will enable those skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, forming a part of this specification.
The invention relates to improvements in chimneys such as are used in the construction of frame buildings. In the formation of a certain class of these chimneys it is the practice to place rectangular flue-sections one upon another and to secure the chimney top in place on the main part of the chimney by mounting it in the roof of the building. In Y such a formation the relative positions of the chimney and the roof change, particularly in a Vertical direction, owing to either the settling of the main part of the chimney or of the building itself independently of the chimney, or to the movement of the roofcaused by atmospheric or climatic conditions which affect the stability of the building. As the main part of the chimney does not depend upon the building proper for its support it is not affected by alterations in the latter; but
as the top of the chimney is supported by the roof any movement of the latter will tend to move the top relatively to the main par-t of the chimney, and thereby open the joint between the two and permit the escape of the products of combustion to set fire to the surrounding woodwork. v
The present invention has for its object the production of a joint between .the top and main part of the chimney that will permit a relative movement of the two without allowing the egress of the-products of combustion.
The invention consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter fully described, pointed out in the appended claims, and illustrated in the accompanying drawing.
The figure in the drawing is a vertical sectional view of a chimney embodying the invention.
The main part of the chimney up to the roof is built up by placing the rectangular flue-sections 1 and the flue-section 2, having a gradually-decreasing cross-area, one upon another, with the latter uppermost. In the upper edge of a lower flue-section is a groove, as at 3, which engages with a tongue or flange, asat 4, projecting from the lower edge of an upper flue-section. The joints between the flue-sections are sealed by any suitable binding material. ney are the usual flue-openings 5.
On the upper end of the flue-section 2 is placed the intermediate flue-section 6, that passes through the roof and projects to a considerable distance above the same. The crossarea dimensions of the intermediate flue-section are such that it .will fit the upper end of the flue-section 2. The connection between the two is also a tongue-andgroove joint sealed by a suitable binding material.
The chimney-top 7 rests on the roof and its base 8 surrounds the projecting upper end of the intermediate fiue-scction 6. The cross area dimensions of the base of the top are considerably larger than those of the entering On the upper edge of the intermediate fluesection is a projecting flange 10, that bears against the inner face of the base of the top and serves to close the upper end of the airspace and prevents the egress of the products of combustion from the chimney. This flange is formed by spreading binding material upon the upper edge of the intermediate flue-section. As there is no connection between the top and the intermediate flue-section the two can move vertically relatively to each other, and as the cross-area dimensions of the base of the top are greater than the entering end of the intermediate flue-section there can also be considerable lateral play between the two.
When the chimney is'constructedin the fore- In the main part of the chimgoing manner, it is obvious that there can be precaution against the overheating of the adjacent parts of the roof, the same acting as a non-conductor.
l/Vhile the herein-described embodiment of the invention is the preferred one, yet it can be departed from to a considerable extent and still be Within the bounds of the improvement.
Having thus described my invention, What I claim, and desire to secure by Letters Patent, is
1. In a chimney, the main lower part of the same, the top supported independently of the main part, and the intermediate flue-section mounted on the main part and extending into said top and movable relatively to the latter and having an air-space intervening between it and the top.
2. In a chimney, the main part of the same, the top supported independently of the main part, the intermediate flue-section mounted on the main part and extending into the said top and movable relatively to the latter, and the flange projecting from the upper edge of the intermediate flue-section and bearing against the inner face of the top.
3. In a chimney, the main lower part of the same, the top supported independently of the main lower part, the intermediate flue-section mounted on the main lower part and extending into said top and movable relatively to the latter and having an air-space intervening between it and the top, and a flange projecting from the upper edge of the intermediate fluesection to bear against the inner face of the top and closing the upper end of said ai r-space.
In testimony whereof l hereunto allix my signature in the presence of two witnesses.
