To a/Z whom it may concern:

jBe it known that we, JAMES P. NESDALL, CHARLES E. CoL'roN, and RHoDY MARA, of Syracuse, in the county'of Onondaga, in the State of New York, have invented new and useful Improvements in Sewers, of which thel the latter passage, yand outlets arrangedV at intervals opening from the upper passage for the discharge of the gases, obnoxious odors, &c.

This invention furthermore consists in the detail construction and arrangement of the sewer shown with a part thereof in section.

It is well known that at present great difdculty exists in constructing sewers, which,

while possessing the essential quality of cheapness, provide for the positive, efficient and practical removal of any gases or obnoxious odors generated or discharged within the same, thus obviating a great amount of unhealthfulness. Our present invention is intended to possess these desirable qualities and is of simpleand practical construction.

-A represents our improved sewer which is shown as egg shaped with the larger end upward, since this shape is particularly ,'conducive to rigidity and strength and is composed of sections or tile -B-B2-B2, C `C-, -E-E-g and -D. The base -B is flat and of considerable width, its outer face extending slightly youtward at -bin- 'stead of conforming strictly to the egg shape of the inner face of the sewer wall, as we deem this a particularly practical and efficient construction ofbas'e tending to render the sewer self-sustaining. The base -B is formed by Vthe central tile -B- and the lower extremi-v ties of tile -B2--B2- arranged on opposite sides thereoff The bases of the central sec- 6o tions or tile -B- is substantially llat, its upper extremity is of less width than its base, and its upright walls incline toward each other from their lower edges upwardly, and are formed with lengthwise shoulders B3- 65 which are arranged substantially midway between the upper and lower'edges thereof, and project from said side walls in planes substantially perpendicular thereto. The bases of the sections or tile B2-62e are substan- 7o tially flat, and are disposed normally in substantially the same plane asl the bases of the central tigle -B, and said tile B2-B2- are formed with their central portions of greater width than their ends and are provided with inner upright walls extending upwardly from their bases and having lengthwisely extending shoulders B4-fwhich are arranged midway between their upper and lower edges,- are substantially perpen- 8o dicular to said inner upright `walls, and interlock with the shoulders `B3e upon the adjacent walls of the interposed-tile -B-. The tile l32-B2- are vformed with upper walls or faces which incline slightly upward from their outer edges inwardly, and are provided midway between their inner and outer edges with lengthwise shoulders -B4- similar to the shoulders B4- previously dejscribed. Said tile -B2- -B2- are each 9o formed with a central upwardly extending web B5-and withcross webs -BG.-. Above the tile -B2-B2-` are tile -C-C- having their upper and lower faces -cformed with locking shoulders -c2- which are simi- 95 lar to the shoulders -B3-B4'-, previously described, and are produced by osetting the inner extremity of said walls from the outer extremity. The shoulders -c2-c2- provided on the lower faces of the lowermost tile roo -CCinterlock with the shoulders B4- upon the upper faces of the tile B2-B2.

Above the tile -C--C- are hollow tile E- rE- arranged with their ends open and contiguous for forming gas passages Ef- EL- running continuously7 from one tile to the other throughout the sewer. Extending through the inner faces of the tile -E-E- ,are perforations -efor permitting the entrance of gas, odors, dac., from the sewage passage -A- to the passages -E-E- 1o and provided at intervals along the sewer wall are man-holes or outlets -G- opening from the passages -E-E- for permitting the upward escape of the gas. rlhe tile composing the sewer wall are firmly locked tot 5 gether by key-tile -D- arranged between the hollow tile -E--E- with theirends contiguous. The tile -C-E-D- are formed with the respective central lengthwise webs C2E2D2 and with the respective cross zo webs -CS-EB-D3 extending in planes substantially perpendicular to the webs C2 -E2-D2-. y Within each of the passages -E-E- is a pipe F through which a heated current is either continually or intermittently passed for effecting a positive circulation of the gases within the sewer and the escape thereof through the passages -E-E- and the outlets -G-.

Instead of the perforations-e, the lower 3o face of the tile -E-E- may be provided with a transverse slot and instead of .using a pipe'-F-, the current may be forced directly through the passages FX-E, although, in that case, as perfect an operation is not effected.

The tile -C.-C, -B and -B2-B2- are also formed hollow, their inner faces and adjacent faces are salt-glazed or vitrified for preventing absorption of the sewage or gases 4o and rendering the sewer perfectly tight, and the ends of said tiles are offset one from the other for producinga rln binding of the whole wall. We do not, however, restrict our invention to a wall composed of hollow tile formed and arranged as described, providing the same is formed with hollow upper tile -E-E at its upper portion forming the gas passages -EE.

Having thus fully described our invention,

5o what we claim as new, and desire to secureby Letters Patent, is-

l. The herein described sewer, the same being composed of a wall consisting of a series of seperable sections or tile inclosinga lengthy wise sewage passage and formed with a lengthwise gas passage connected to the former passage and inclosed by the outer walls of hollow tile at the upper part of the sewer wall arranged with their ends contiguous, and formed 6o also with perforations extending through the lower walls of said hollow tile, and with outlets forthe gas passage arranged at intervals along the passage for the escape of the gas, substantially as and for the purpose set forth.

2. The herein described sewer, the same being composed of a wall consisting of a series of .separable sections or tile inclosingalengthwise sewage passage and provided with central key tiles and hollow tiles arranged on opposite sides of the key tiles with their ends contiguous and open for forming an inclosed gas passage said wall having perforations extending through the lower wall of the hollow tile for permitting the entrance of gas `and with outlets arranged at intervals along said passage for the escape of the gas, substantially as and for the purpose specified.

3. The herein described sewer, the same comprising an inclosing wall, a sewage passage inclosed by the wall, hollowtile at the upper part ofv the sewer having open ends contiguously arranged for forming a gas passage in the upper part of the sewer, perforations connecting one passage with the other for the entrance of gas to the latter passage, and a pipe for conveying a heated current within said upper passage and producing a circulation of the gases, substantially as and for the purpose specified.

4. The herein described sewer, the samebeing composed of an inclosing wall, a sewage passage inclosed by the wall, a gas passage in the upper part of the sewer wall for the gas, perforations connecting one passage with the other for the entrance of gas to the latter passage, a series of outlets arranged at intervals along said wall and opening from the upper passage for the outlet of the gas, and a pipe for conveying a heated current within said upper passage and producing a circulation of the gases, substantially as and for the purpose set forth.
