SPECIFICATION forming `part of Letters Patent No. 273,945, dated March 13, 1883, Application nien octoberV 13, Issa.' (No model.) Y

To all whom it may concern Be it known that we, REUBEN T. BRYANT and DAVID TosTE'vIN, ofCouncil Bluffs, in the county of Pottawattamie, and in the State ot' Iowa, have invented certain new and useful Improvements iu Sewerage, 8vo. and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements `in the construction of. sewers, drains,

eulverts, wells, and cisterns, open arches for buildings and other purposes, and tunnels and other like structures, as will be more fully hereinafter pointed out.

In the drawings, Figure l represents a perspective view of ourimprovement as applied to a sewer; Fig. 2, a transverse section ofthe saine; and Fig. 3, alike view, showing a inodiiied form of section.

rIheletterA indicates a series of sections, which may be constructed ot cast metal, artiticial stone, prepared wood, baked clay, or any The.. said sections are wedge-shaped in crosssection, so that when built up they will form a polygonal structure, as indicated in the drawings. The adjoining edges of the sections are provided with lougitudinal semi-cylindrical grooves, which form longitudinal cylindrical passages 'in the walls of the structure. Said semi-cylindrical longitudin al grooves are provided with depressions or recesses Vat suitable intervals apart, and the longitudinal tubes,(hereinafter men tioned,) which tit within said grooves, with lugs or projections b, corresponding in location and size with the4 depressions,'the lugs and depressions being adapted to register or tit one within the other, and thereby hold the sections more se- In the passages above referred to are located the longitudinal tubesB, which serve to key the parts together, and as air or water passages, as may be required. The tubes B are usually built up with thewalls, and are provided with external lugs or projections, for the purpose above indicated. The sections, as well as the cylinders or tubes, are arranged to break joint at the ends in .the finished structure, the cylinders or tubes being jointed at their ends and laid within the sections in cement, making the walls ofthe structure water-tight. The structure, by properly beveling the sections, may be built in the form (in crosssection) of a circle, semicircle, parabola, or ellipse approximately, the exterior and interior walls being polygonal for the purpose -ofsecuring strength. When used simply as a sewer, the structlire may be provided with drain -connections emptying directly in its interior. l

In many cities and towns there are small creeks fed by springs passing through them, and it is often desirable to preserve the water uncontaminated to be utilized for domestic or mechanical purposes. In most cases these creek-courses are the only available drainways. In such cases we perforate the cylinders or tubes in the main wall, and conduct the gutterage and surface water through them, keeping the water in the main drain clear and uncontaminated; or we conduct the clear water through the tubes, the inner passage serving as the sewer. The letters O and D indicate conductors for this purpose. For wells or cisterns the structure is set vertically, and for cisterns thel sections are reduced in tlhickness, bringing the cylinders closer together, forming a series of closely-set air-chambers, which prevents injury by frost.

Having thus described our invention, what we claim, and desire to secure by Letters Patstructed as described, the connections leading Y In testimony whereof weaflix our signatures, 1o into theinterior andinto the longitudinal tubes, in presence of two Witnesses, this 20th day of substantially as and for the purposes set forth. September, 1882.
