SEWER.

S?EGIFICATION forming part of Letters Patent No. 738,645, dated September 8, 1903.

Application filed November 6, 1902. Serial No- 130j244. (No model.)

To a, whom it may concern:-

Be it known that I, CARL WENTZIEN, a citizen of the United States,residing' at Hoboken, in thecounty of Hudson, State of New Jersey, have invented new and useful Improvements in Sewers, of which the following is a specification.

My invention consists of a sewer which is provided with aseparate chamber or passage for sewer-gas and means for discharging the latter into the atmosphere.

It also consists in providing a sewer witha chamber for sediment or solid matters and means for access to said chamber.

Figure 1 represents .a longitudinal vertical Fig. 2 represents a transverse vertical section thereof. Fig. 3 represents a top or plan view of a portion thereof.

' Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a sewer, above the roof B of whichis a 1ongitudinally-extending arched wall 0, whose sides are united to the wall of the sewer and form a channel or passage D,which while being a chamber separate from the sewer is in com mnnication with the latter by means of the openings or ports E in the roof B, the wall of the sewer being perfectly cylindrical.

In the wall 0 is a nozzle or nipple F for attachment of a pipe or flue leading above the ground, it being noticed that while fluids,

* &c.,may flow through the sewer,as usual, the

existin as known as sewer as asses through the openings E, into the channel D,

from which it escapes intothe atmosphere through the nozzle or nipple F as the outlet of said channel anda pipe extending above the street or road. The ports E extend substantially the full width of the roof, so as to avoid any obstruction to the free passage of the gas from the sewer into the channel D.

Connected .withthe sewer is the communicating-chamber G, which is below the floor thereof, so that dirt, filth, or other solid matter or sediment will be trapped and lodged in said chamber A, the water and fluid, however, flowing over the same; Rising from the sewer over the chamber G is the man= hole H, which admits of access to said chamher for removing the sediment therefrom and other purposes. The'manhole is closed by a cover J, which may be removed as occasion .requires.

The upper wall of the channel D is preferably elliptical in its nature and also serves as a guard to the top proper or root of the sewer against the injurious action of the superimposed weight thereon, so that said. roof, though having the openings or ports E for the escape of the sewer-gas from the sewer into said channel, is not liable to be depressed or crushed in by said weight and leakage from the street into the conduit is prevented, while the channel D and outlets therefrom to the atmosphere prevent severe accumulation of sewer-gas in the manhole and explosions therein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1 In a sewer, the combination with a 1011- gitudinally-extending chamber which is beyond the roof and separate from the sewer and in communication therewith, with the side walls of said chamber merging into those of the sewer, the walls of said roof and chamber being upon different arcs.

2. A sewer in combination with a channel for the escape of sewer-gas, the covering-wall of said chamber being in addition to and merging into the wall of the. sewer, the roof of said sewer having ports therein forming a communication between said sewer and. channel, said ports extending substantially the full width of said channel.

3. A sewer, in combination with a separate chamber extending in the longitudinal direction of the sewer and above the roof thereof, the wall of said chamber being integral. with that of the sewer and the wall forming the division between the said chamber and sewer proper being provided with a port, the wall of said chamber above the division-wall being upon a difierent arc and forming a guard for said divisiomwall.

4. A sewer in combination with a longitudinally-extending channel in combination with the same for the escape of sewer-gas, the covering wall of said channel being .mounted on the sewer and formed integral therewith, the top wall of the latter having a port therein forming a communication bethe atmosphere, the walls of said chamber tween the said channel and sewer, said covering-wall forming a guard for said top wall.

5. In a sewer, a separate chamber extending in the longitudinal direction of the sewer above and independent of the roof thereof and communicating with said sewer and with forming continuations of the walls of the sewer, said sewer being formed witha sedi-. ment-chamber extending below the lower wall thereof, and a manhole above said independent chamber and in communication with the sediment-chamber,and disconnected from said separate chamber.

7. In combination with a sewer, a separate chamber extending in the longitudinal direction thereof and independent of the roof of said sewer, the upper wall of said chamber a being, elliptical in form and integral with the walls of the sewer. v

CARL WENTZIEN.
