CHIMNEY.

Specification of Letter: Paton-t.

Patented Jan. 12, 1909.

Application filed July 27, 1908. Serial No. 445,661.

To all whom. it may concern:

Be it known that I, MILO E. Hows, citizen of the United States, residing at Morris, in the county of Grundy and State of Illinois, have invented certain new and useful Imrovements in Chimneys, of which the folowing is a specification.

This invention relates to chimneys, and has for its object to provide an improved chimney constructed of concrete and made of sections which are molded in advance and which can be quickly set up to form a chimney which will be permanent and fire proof.

Brick chimneys have the defect that the mortar decays and drops out, causing loose bricks and open .joints, allowing the chimney to fall, and also bein unsafe because of fire. By the use of molded'sections made of concrete and extending entirely around the flue, and joined together by cement, these disadvantages and dangers are avoided. The sections are molded and put together with doweled joints,and when completed form substantial] one solid piece of cement of great durabi ity. The chimney can be built by inexperienced persons, since it only requires that one block or section be put upon another until the desired height is reached. This can be done very quickly and in a small fraction of the time required to build a brick chimney. By variation of the molds and the sections, chimneys of different'kinds can be made, containing one or more lines as desired.

The nature of the invention will be more fully ap arent from the following description an the accompanying drawings in which Figure 1 is a perspective view of part of a. chimney, some of the blocks being removed in order to show the interior construction; Fig. 2 is a perspective view of one of the blocks so removed; 3 is a. perspective View of a cap piece; igs. 4: and 5 are respectively perspective views of up er and lower sections of an ornamental head for the chimney; Fig. 6 is a perspective View of a hooded head.

In Fig. 1, a two-flue chimney is shown. This is made of sections which are respectively single and double. One of the single sectionsis shown in Fig. 2 at 6. One of,

the double sections is shown in Fig. 1 at 7. The former consists of a hollow rectangular block forming a single flue. This is united with or placed beside a similar block. to

sections.

form a double flue chimney. The double block 7 is referably only half the hei ht of the sing c section and contains two ue openings separated by a cross wall 8 at the middle. This double section extends across 'the entire chimney and serves to assist in binding the same together. The single sec tions (3 may be built up for one, two or more courses, and then one of the bonding sections 7 is placed thereon, and then additional single sections are added, with double sections at intervals, until the desired height of chimne is reached. At the top the ch1m ney may ended by a plain cap block or section as indicated at 9. Or, one of the other heads may be used. The two blocks shown in Figs. 4 and 5 when united form an enlarged head of ornamental appearance. The hooded head shown in Fi 6 is useful under certain conditions. The latter may be molded in one-piece by the use of a proper mold and core. a

The block sections are preferably marked or scored on the outside to represent brick, as shown in the drawin but a lain or other finish may be used instead. he sections are united by cement, and doweled joints are formed by means of holes or depressions 10 in the to and bottom of the These doweli-d holes correspond with each other in the various sections, and when the cement is applied and the sections are built together the cement will enter the holes and form a very effective bond which will hold the chimney together without the use of other fastening devices.

For a single flue chimney the single sections only are used, being built one upon the other until the desired height is reached. It is obvious that this may be done very uickly. By making the sections a foot hig it is only a few minutes work to set one upon the other to form a chimney several stories high. By making the walls of the sections extend entirely around the flue, and cementcapable of being made in standard sizes or plurality of flue openings, and each block 10 can be made in special molds to suit special conditions.

I claim:

A chimney built of molded cement blocks some of the blocks having a single flue opening through the same and placed in courses with a plurality of blocks in each course, and other bonding blocks having a forming a course.

In testimony whereof, I aflix my signature in presence of two wltnesses.
