W'ILLIAM JAMES OULNAN, OF BRULE, WISCONSIN.
SECTIONAL CHIMNEY.
SPECIFICATION forming part of Letters Patent No. 516,966, dated March 20, 1894. Application led August l2, 1893. Serial No. 482,957. (No model.)
To all whom it may concern.-
Beit known that I, WILLIAM JAMES CUL- NAN, a citizen of the United States, residing at Brule, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Sectional Chimneys; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improved continuoussectional chimneyhaving air passages between the inner and outer walls or mem-l bers and consists in certain novel construc-A tions and arrangements of parts to'be herneinafter described and claimed.
In the accompanying drawings Figure l, is a front elevation of my chimney. Fig. 2, is a vertical section of the same showing the relative arrangement and method of supporting and bracing the inner and outer series of sections. Fi g. 3 is a cross-section of Fig. 1. Fig. 4 is a detail view in perspective of one section or length of smoke chimney while Fig. 5 shows detachable ribs of diderent sizes.
A in the accompanying drawings represents the chimney complete, which is composed of a series of sections or lengths B, which may be of any desired number, forming an outer casing or wall, and a series of somewhat similar shaped sections C. C. of corresponding number, forming an inner flue or smoke chimney. VThe inner flue or smoke chimney is of much less diameter than the outer casing and is arranged concentric tothe outer chimney member in order to provide a vertical air passage E. between the respective walls of the chimney members, for the purpose of preventing their becoming'unduly hot. The sections of the respective members may be of corresponding length and are supported vertically and exactly in line by socketing together of the adjacent ends of each section. One end of eachtsection of the outer chimney member B is provided with a reduced end D which is adapted to tit snugly into the straight larger end of the next adjacent section between the inner iiue and the outer casing thereby forming a tight joint and keeping the exterior walls of each section in the series, in perfect alignment. Each of the sections of the outer casin g is also provided on its inner surface near its reduced end with a shoulder which prevents the inner section or smoke flue loeing pushed in too far during theV act of inserting the same within the outer'casing.
One end of each section of the inner chimney member C is enlarged forming swelled sides that allow of the insertion of the smaller straightend of the next adjacent inner section thus affording a gas proof joint opposite the corresponding break joint in the'chimney member While preserving a uniform alignment of the surfaces forming the walls of the inner iiue or smoke passage. The inner chimney or iue is supported concentrically within the exterior wall member by means of vertically removable ribs,the edge faces of which slide respectively into grooves formed by the beads located on the exterior sides of each section of the inner chimney and the` corresponding interior sides of each section forming the outer chimney, and thereby locking them together. The ribs are formed of channeled iron with inner and outer interlocking heads g. g. which fit in the corresponding interlocking grooves h and by reason of their shape the ribs are entered from the top or bottom of the section, and to be removed are slid out in the same manner in which they are entered. By this construction it'is impossible for the ribs to accidentally become loosened or to laterally move out of place. The ribs are shown as being rounded in shape to match their corresponding grooves and thereby affording a means for easily inserting and withdrawing the same from its respective groove or socket.
I propose for convenience and economy to establish two or more standard sizes (varying in diameter only) of the outer and inner chimney sections which can be used interchangeably by simply substituting ribs varying in width, so as to maintain a sufficient space for the vertical air passage. Any one or more of these sections thus locked can be adapted for thereception of a draftv aperture by passing a thimble H from the outside tothe inside of the chimney to receive a stove pipe end or to make other suitable connections for draft purposes; and the supporting rib located between the sides penetrated by said thimble may be divided into sections and inserted as shown at j. j. for bracing and steadying the same. In the bottom section there is shown a pan or drawer K. adapted to tit into and form the bottom of the centralchimney and to serve as a sootv collector, which may be withdrawn and emptied as circumstances may require.
The sections comprising the top length of the chimney are provided with a cap I. having a central opening of a size to coincide with the diameter of the inner smoke passage or flue and adapted to snugly fit over the upper end portion of the outer chimney thus affording a covering to thetop of the airspace and adding to the ornamental appearance of the chimney. It will also be observed by having the spacing and strengthening ribs removable and of dierent widths, that not only can different sized inner fiues be used with the same outer casing and vice versa, but that in the event of one or more of the ribs getting broken off in handling or otherwise they could be readily replaced by new ones, whereas if they were made homogeneous with the inner Hue or formed on the outer casing, this could not be done, the great inconvenience of which is apparent.
What I claim is- 1. In a sectional chimney, the combination of two or more jointed sections, each section comprising an outer casing and a concentrically arrangedinner flue, vertical guiding and holding beads, and removable spacing and holding ribs inserted in the airspace between the inner and the outer casing, one end of the outer casing being provided with a joint shoulder and reduced to enter the air space formed between the inner tlue and the outer casing of an adjoining section, and the outer casing also provided on its inner surface near its reduced end with a shoulder which prevents the inner casing from being pushed in too far, substantially as described.
2. In a sectional chimney, the combination of two or more jointed sections, each section comprising an outer easing and a concentrically arranged inner ilue, vertical guiding holding beads and removable spacing and holding ribs inserted into the air space between the inner and outer casing one end of the outer casing being provided with a joint shoulder and reduced to enter the air space formed between the inner liuc and the outer casing of an adjoining section and the outer casing provided on its inner surface near its reduced end with a shoulder which prevents the inner casing from being pushed in too far; and one end of the inner flue being formed with a joint shoulder and enlarged to receive the smaller end of the inner flue, whereby, when one or more sections of the chimney are united, continuous gas tight joints are formed between the adjoining ends of the sections of the inner iiue and the connecting ends of the sections of the outer casing, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
