FLUE.
SPECIFICATION forming part of Letters Patent N0. 527,256, dated October 9, 1894.` Application filed April 30, 1894:. Serial No. 509.439. ND model.)
To @ZZ whom it may concern.-
Be it known that we,`FRANCIS B. WISDOM and EDWARD G. WISDOM, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flues, of which the following is a specification.
The flue which forms the subject of the present invention may be used either in the identical form shown in the drawings, or under a modified form for chimneys, or for conveying hot air through a building for heating purposes, or for any other purpose for which iiues are used. The iiue is, however, designed more especially for use as a chimney, and the following description will be confined to a iiue embodying the invention and used for this purpose, it being understood that the claims are not to be considered as so limited, excepting where they include features that are strictly peculiar to chimneys.
One of the objects of the presentinvention is to provide a iiue which may be constructed more quickly and ata less expense than the brick iiue of ordinary construction, and another object of the invention is to provide a iiue which is superior to a brick flue of the ordinary construction, in that it more effectually prevents the'heat and products of com-` bustion passing through it from igniting the wood-work of the building.
To these ends the invention consists in the features of novelty that are particularly pointed out in the claims hereinafter, and in order that it may be fully understood We will describe it with reference to the accompanying drawings, which are made a part of this specilication, and in which- Figure 1 is a vertical section of a iiue embodying the invention and used for the purpose of a chimney, an intermediate portion of the flue being broken away to indicate indefiniteness in length. Fig. 2 is a vertical section of a portion of said due on a somewhat larger scale. Figs. Sand l are perspective views of two forms of a part hereinafter called aebridge. Fig. 5 is a horizontal section on the line 5-5, Fig. l. Fig. Gis aperspective view The improved flue is constructed of double walls A and B, located at suchdistance apart as to leave between them an air-space C. In the drawings we have showna flue of rectangular shape in horizontal cross-section,but it will of course be understood that this is not essential, and that a flue of circular or any other shape in horizontal cross-section is within the scope of the invention and is the full equivalentof what is shown. `The rectangular shape is shown .simply because, for the purposes of this application we prefer to illustrate our invention as embodied in a improved chimney as extendsabove the roof of pipes molded to simulate brick.`
Each wall of Athe flue is constructed of a number of sections of pipe, placed one upon another and preferably so arranged that the courses or lifts ofthe two walls correspond, bringing the joints of one wall directly oppo site the joints of the other wall. Upon the top of each lift is placed a number of parts D, hereinafter called bridges, each of which rests upon both walls and spans the space between them. These bridges are preferably constructed of` metal, and may be constructed either of narrow strips of metal, as shown in Figs. 1 and 3, or of `wide strips of metal, as shown in Fig. 4, in which latter case four bridges are used at each lift, each extending along one side `of the flue. We prefer to construct them as shown in Figs. land 3, and to A Other objects in bending the bridges downroo spaces between the walls and ring, substanawind-guard supported by said brackets, subtially as set forth. stantially as set forth.
7. A ue,having double walls, bridges rest- FRANCIS B. WISDOM. ing upon the top of the flue and having por- EDWARD G. WISDOM. 5 `tions bent downward between said walls, a Witnesses: v
ring supported by said bridges, brackets HENRY W. THOMPSON,
formed in continuation O f said bridges, and" THOMAS B. WISDOM.
