To all whom it may concern.

Be it known that I, Frnn M. STILES, a. citizen of the United States, residing at Cooperstown, in the county of Otsego and State of New York, have invented a new and useful Chimney, of which the following is a specification.

It is the object of the, present invention to provide an improved construction of chimney and the invention aims primarily to provide a chimney which will be fire proof and will embody ventilating means for the purpose of admitting cooling air into the space between the inner and outer sections of which the chimney is composed.

A 't'urther object of the invention is to provide a chimney of the class mentioned embodying. wedges which are disposed between the corners of corresponding inner and outer sections for the purpose of holding these sections inv proper spaced relation.

It is a further object of the invention to provide, in a-ehimney made up of a plurality of sections including an inner base or bottom section and an outer base or bot tom section, means for so spacing the bottoms of the two said sections as to not inter- .fere with the circulation of cooling air currents therearound.

lVith the above and other objects in view, the invention consists in the general construction and arrangement of parts shown in the accompanying drawings, in which,

Figure 1 is a perspective view partly in section of a chimney constructed in accordance with the present invention. Fig. 2 is a similar View in detail of one' corner or" two related sections of the chimney. Fig. 3 is a vertical sectional view through the upper end portion of one side of the chimney wall. Fig. 4 is a. detail perspective view of the means provided for s acing the bottoms of the base sections of tie chimney. Fig. 5 is a perspective View of one of the wedge shaped blocks.

As heretofore stated, the chimney embodying the present invention is made up of a plurality of superposed inner and outer sections and the inner course of sections includes a bottom section of specific construc-' tion as does also the bottonrcourse, and the chimney further includes, in its structure,

tom section of the inner course is indicated 1 the numeral 5 and a bottom wall indicated,

by the numeral 6, this section being open at its top. In a likenianner, the bottom section B of the outer course'of sections, embodies four vertical Walls 7 and a bottom wall 8. The section B is considerably largerthan the section A and in building the chimney the section A is disposed within the section B angl as a means for spacing'the' bottom Wall 6. of the section A from the bottom wall 8 of the section B, there is provided a spaningmember comprising four radialarzns 9 which are relatively narrow and are of they desired height and have their ends'beveled as at 10 so as to fitsnugly in the corners be-' tween the vertical walls 7' of the section B, it being observed that the section A is dis posed directly upon this spacing member. For the purpose of providing for the.connection of a stove pipe with the chimney, a stove pipe thimble indicated by the numeral 11. is fitted through one or more vertical walls 7 of the section B and opens also through the corresponding wall of the section A and consequently into the interior of the section A. The vertical wall of the section B has its upper edge rabbeted as indi;- cated by the numeral 12 and its outer edge beveled as at 13 whereby to shed water. In a like manner, the. upper edge of each vertical wall section A. is rabbeted as at i l and also its inner upper edge is beveled.

In addition to the bottom section above described, the chimney includes, in its structure, a plurality of intermediate sections and .of these latter sections, those comprising the inner course are indicated by the numeral, 15 and those comprising the outer eour'se'are indicated by the numeral 16. Each section 15, of which there may beanynumber, as-

will be readily understood, embodies four vertical walls and is open at its top and its bottom and the lower edge of each wall of each section 15 is rabbeted as at 17 as is also the upper edge of each Wall as at 18. The lowermost one of the sections 15 is disposed ei ia M211 at its lower end upon the upper end of the section it with the m hheiecl edges 17 of its vertical "Well fitting the rahhoteri upper edge:-

oi? the Wall o1" the section it and the red maining ones of the sections 15 are disposed, in SE1; erposed. relation, epi'sn the sectiois above specifically referred to. in like manner, the lower edge of each vertical. wall of the sections i6 is rabhctecl as at 1.9 and its upper edge as at 20 and, these sections l are assemhietl in the same manner ar the sections 15, as clearly illustrated in 1 of the drawings.

From en inspection of Fig. 1 of the draw- 5 ing's it will he observed that the sections and 16 are of the same height so that when the sections are properly arrangel, the lower and upper edges of: corremtmrling sections fiviillhe locatee. in the same horizontal plane.

, on. as well as the heso section A each upper corner with c 1) indicated by the numeral properly space the sections oi' the ter courses there are i revii spacing wedges indicated by the nnniierel he, one end of each. of the we figes being 2 e 1 as at 23 L in V-forrn, so as to fit in the cor} er hetvxee i adjacent vertical walls of the enter section which is to be spaced from the cor- 0 responding inner section, anti. the inn end oi each Wedge 22 is formed with e notcn which is also V-siiaped and is cleeper at bottom than at the top, the Wedge heint posed in the position shown in oi.
