VENTlLATlNG-CHIMNEYI SPECIFICATION forming part of Letter S Patent No. 555,643, dated March 3, 1896.

Application filed February 18, 1895. Serial No. 588,764. (No model.)

T0 to whom it Ina/y concern:

Be it known that LWILLIAM J. GORDON, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Ventilating-Chimneys; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in ventilating-chimneys, and has for its object the production of a chimney that will insure perfect ventilation.

A further object is to provide a chimney in which the hot air entering the flue from the stove may be utilized for heating rooms above the thimble where the stovepipe enters the flue.

Referring to the drawings accompanying and forming part of this specification, in which like letters of reference denote the same parts throughout the several views, Figure 1 represents a perspective view of my invention. Fig. 2 is .a plan view taken on the line a; 00 of Fig. 1. Fig. 3 shows the construction of the chimney immediately under and above the roof. Fig. at is a perspective view showing manner of ventilating channel 1'. Fig. 5 shows construction of section 0. Fig. 6 shows construction of side sections a a. Fig. 7 shows construction of section b. Fig. 8 is a perspective view of the bolt d and nuts 9 9 used in assembling my invention. Fig. 9 shows the construction of the inner flue. Fig. 10 shows the plate I) provided with a thimble 71' Fig. 11 is a perspective view of the base n. Fig. 12- is a perspective view of the cap 1). Fig. 13 is a perspective view of the portion q. Fig. 14 shows the construction of the outer casing, c. Fig. 15 shows one of the pieces q.

My ventilating chimney-flue consists of an outer casing, 71, of sheet metal, and an inner casing made up of four vertical series of plates at, a, b and c, fitted together by the edges of the two former plates entering grooves c in plates 1) 0. These plates are secured in position by bolts cl, which pass through holes or eyes 6 in overlapping ends of plates 1) 0. These bolts are provided with long nuts g, having on their outer faces projections u for engaging holes in the said outer casing, t, to hold it in place. The said nuts and the ends of plates 0, which are extended farther than the ends of plates I), maintain a space between the outer and inner casings, which space is divided by the said ends of plates c into two vertical passages h i, the former constituting a fresh-air flue and the latter a foul-air flue. The lowest plates, 1) c, are provided at bottom with outwardly-bent and downwardly-extending parts to, which constitute feet or a base. The plates 1) are provided with. thimbles k for receiving the ends of smoke-pipes, there being as many of said thimbles as there are pipes entering the smoke-flue.

Air is admitted to the passage h by a ventilator Z near the bottom of the chimney. There may be such ventilators at any points of the flue where convenient. In passing the thimbles k such air will he heated and may be subsequently allowed to pass out through exit-openings Z in the casing 11 for calorific uses. In the lower edge of the lowest section of this outer casing I provide an opening y to allow the removal of soot, &c.

The foul-air fine or passage 1; allows the connection of vaults, sewers and drainage for ventilation without risk of poisonous gases escaping into inhabited parts of the building. It is provided with an escape-pipe m extending from the upper end of the said passage through the roof.

The chimney is surrounded above the roof by a cap-base n, which is spiked to the roof through the flanges n n of the said base. The angle of the lower part of the said base corresponds to the pitch of the roof. On this base the cap 19 of any suitable material is secured in any convenient manner. Pieces q are secured to the interior thereof and extend inwardly and downwardly in the shape of a funnel, provided at the lower end with shoulders and flanges 0", which engage with the top of the innercasing. These pieces may be constructed as shown in Fig. 15, or they may be made of one solid piece, as shown in Fig. 13. This funnel-like device directs into the inner flue all rain, snow or hail which falls into the upper end of the chimney, so that none can run down the outside of the inner flue.

The parts of the chimney being assembled and secured as stated, and the smoke pipe or pipes being connected to the thiinble or thinlbles k, the starting of the fires will create a draft through the inner flue and will also heat the thimbles 7c, which in turn will heat the fresh air that reaches them by the ventilator or ventilators, as aforesaid, thus making or increasing a draft through the passage or flue hand fitting this air to be used through openings Z or suitable registers for heating rooms or halls. The passage or flue i is connected to a sewer, cellar or other place or channel which is to be ventilated, and the heating of the said passage through the inner casing will cause the gases to ascend from the said sewer and escape.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. I11 combination with an outer casing for a chimney an inner easing consisting of interlocking plates arranged in series and bolted together, the nuts of the bolts being long enough to assist in keeping the two casings apart but provided with projections to hold it in place substantially as set forth.

2. In combination with the outer casing of a ventilating-chininey, an inner casing consisting of four series of plates which make up its sides, the plates of one series being extended at one end far enough to divide the space between the casings into two passages or fines one of which may be used for fresh air to be heated and supplied to rooms and the other for foul air escaping from sewers (be. substantially as set forth.

3. In a ventilating-ehimney, the combination of the outer and inner casings with a capbase surrounding the same above the roof and a cap attached to the said base and provided with a funnel-like attachment which directs into the inner casing the snow rain and hall which falls into the said cap sub stantially as set forth.

In testimony whereof I aliix my signature in presence of two witnesses.

\VILLIAM J. GORDON.
