CHIMNEY ICONSTRUCTION.

Specification of Letters Patent.

Patented July 9, 1907.

Application iled August 9. 1.9.06. `Serial No. 329,808.

To all whom it may concern:

Be it known that I, ANDREA REPETTO, a citizen oi Italy, residing in thecity and county of San Francisco and State oi` California, have invented new and useful Improvements in Chimney Constructions, of which the following is a specification.

My invention relates to building construction, and especially to improvements in chimneys. Its chief objects are to provide a chimney which shall be earthquake prooi; which shall have air passages for carrying ofi the foul vapors from basements and rooms of buildings; which shall have means for purifying these vapors before allowing them to escape to the outer air; which shall have hollow columns running lengthwise of the chimneyand serving both to bond the component elements oi the structure together and to serve as stand-y pipes ior water, the pipes being adaptedjo open into the dues in such way that in case the `chimney catches on tire the water can be quickly turned on to quench the blaze.

The invention consists oi the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure l is a vertical section through the chimney. Fig. 2 is a perspective view o a member. Fig. 3 is a plan view of same, with parts in section.

The chimney may be made of artificial stone,'likc granite or marble, plain, hewn, or polished in imitation of granite, marble, or any other kind of stone that 'can be imitated. It may be made of blocks o concrete oi any size and shape,-square, rectangular, polygonal, etc., and may be carried to any height. The chimney may also be made of one pieceii desired. The blocks may be made plain or ornamental, provided with landscapeor iigures, and bas relief.

In the construction oi my improved chimney I prefer to use a block A, such as shown in Fig. A2. This block is provided with one or more flues 2 which may be lined with terra cotta, sheet iron or other suitable material as indicated at 3. The block is perforated at the corners, or any other suitable points as shown at 4 for the passage of the vertical hollow columns or pipes 5, Fig. l. Beside the perforations 4 are the vertical air lues or passages 6.

The upper face of each block is provided with a surrounding bead or shallow rectangular tongue a arranged in line with and intersected by the holes 4-5g and the under side oi each block has a corresponding continuous groove b to receive the bead or tongue a on succeeding block below. Thus one block matches nicely into another and all the blocks in the column are firmly united against any independent lateral movement. The inside top and bottom beading and grooving, is easy to produce in the manufacture o the bricks or blocks. Besides by leaving the full end and side areas oi the blocks they look from `the outside like any ordinary block; the interlocking means being entirely hidden from view. In the construction of the chimney these blocks are placed one on the top of the other and made properly to interlock; the blocks being suitably bonded together by a filling of mortar or cement. The air flues 6 are adapted to register with one another, and the hollow columns or pipes 5 which pass through the perforations o the column, and the lowermost oi the pipes 5 are provided with suitable anchor means as the barbs or 4 lukes 7 by which the said pipes are suitably anchored in the foundation. The pipes 5 are preferably in sections; each section having a length corresponding about to the height of six blocks. Having placed a number oi blocks in position corresponding approximately to the length oi .a pipe section, a metal plate 8 is slipped over the end of the section and the nipple or union 9 by which succeeding pipe-sections are united, is screwed on over the already emplaced section and down on its plate 8; thus serving as a nut on the pipe to lock the plate in position and lock all the blocks below into a rigid structure. The succeeding section of pipe is then screwed into the nipple and the building operation goes on as before until the end of this section oi pipe is reached, when another plate 8 is put on, a nipple is screwed down on to it and the work goes on as before.

When the chimney has reached a suicient height an elbow portion l() is screwed into the last nipple in continuation oi a corresponding pipe section or hollow column with the elbows turned so as to discharge into a smoke iue 2. The several pipeslare connected in any suitable manner and at any proper point with the Water main, and the flow to andthrough the pipes may be controlled by a cock, as indicated at ll. Ii desired the pipes may be maintained iull of water so as to assist in keeping the chimney cool. At suitable points in the height oi the chimney certain oi the blocks A may have lateral openings l2, opening into either the basement or into any o the rooms on the different floors, through or adjacent to which the chimney passes. These openings may be provided with ventilators as indicated at I3.

The chimney is capped by a suitable cowl 14, which is preferably o dome shape with its edge upturned to orm an annular trough l5 to contain any suitable disinfectant medium. Above the cowl is arranged a covering or hood 16, which has its lower edge separated by a small space as 17 from the outer edge oi the cowl 1.4. Pipes 18 extending upward from the air passages 6 in the chimney open into the space I9 inclosed by the cowl and hood. The heat from the smoke lues create not only a circulation through the air iues but also acts to destroy such germs as arerwithdrawn from the chambers below.

The water pipes or columns, serve three purposes: (l) to bond the blocks oi the chimney together; (2) to re duce the temperature oi the flues, (3) and to serve as Having thus described my invention,r what I claim and desire to secure by Letters Patent is-L- 1. An improved chimney construction consisting of blocks seated one on the other in vertical order, said blocks having two series of holes through them with the holes of each series adapted to register, both series of holes being made through the body of the blocks, and one of said series of registering holes forming a ue, tubular sections passing through the other series of registering holes, washers loosely fitting said sections and seated on the blocks and nipples for uniting the ends of said sections and' acting against said Washers, said tubular sections, nipples and washers serving to bond the blocks of the chimney together and act as a iluid conductor, and fluid connections with the bottom of the sections.

2. An improved i chimney construction consisting of building blocks laid in vertical order and having regis tering holes forming a continuous ue, said blocks having other registering openings made through them and tubular sections passing through said other` openings and bonding the blocks together, threaded nipples between the adjacent ends of said sections, some of said sections extending to a point above the top of the chimney and having return bends discharging into said iue, the lowermost of said sections having barbs or flukes by which they may be anchored in the foundation of the chimney.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
