Engineer. "IMPROVEMENTS IN SEWER PIPE CONNECTIONS AND STENCH TRAPS.".
A communication from abroad by Jesse Edward Folk, of the City of Brooklyn,
County of Kings, and State of New York, in the United States of America.
(Manufacturer).
The object of my Invention is to provide more certain and effective means of
preventing the admission of sewer gas into dwellings. Among the various means
heretofore introduced to accomplish this purpose has been the extension of the.
vertical soil pipe upwardly opening into the air above the roof, so that the tendency.
of the sewer gas will be to escape therefrom instead of passing through the traps.
and into the rooms of the house. This method however while obviating the
difficulty to some extent, does not do so completely, because if there be traps on
several floors of a house and the upper one for instance be discharged and the:
vertical soil pipe into which it discharges be of the same size as the trap, the body.
of water descending in a substantially solid mass, compresses the sewer gas in the
pipe ahead of it, and causes more or less of it to be forced through the adjacent
traps into the rooms below it. The traps as usual are connected with the vertical
soil pipes and have a descent from their outlets to their ends where they enter the
soil pipes; the highest point of the traps at their outlets thus retaining sewer gas,
which cannot readily pass back into the soil pipe and escape at the top opening.
My Invention comprises in sewer pipe connections a gas pipe separate from the
soil or discharge pipe, and connected by branches to the traps at the outlets of the
latter, and arranged to carry off the sewer gas entering the traps.. It further
comprises the combination of the soil or discharge pipes, one or more traps entering
and discharging into said soil pipe and a gas pipe separate from the soil pipe and
connected independently of the latter with the traps at the tops or upper parts of
the trap outlets.

PHILIP SYNG JUSTICE, of 14, Southampton Buildings, in the County of Middlesex,
Engineer. "IMPROVEMENTS IN SEWER PIPE CONNECTIONS AND STENCH TRaps."
A communication from abroad by Jesse Edward Folk, of the City of Brooklyn,
County of Kings, and State of New York, in the United States of America
(Manufacturer).
The object of this Invention is to provide more certain and effective means of
preventing the admission of sewer gas into dwellings or other buildings. Among
the various means heretofore introduced to accomplish this purpose has been the
extension of the vertical soil pipe upward, opening into the air above the roof so
that the tendency of the sewer gas will be to escape therefrom instead of passing
through the traps into the rooms of the house. And in addition to this, the traps
have in some instances been connected by branches one from each trap, at the
upper part or outlet proper of the latter to the soil pipe at a point therein above
that at which such trap empties into the soil pipe. These methods however while
undoubtedly obviating the difficulty to some extent do not do so completely
because when the improvement has simply been to extend the vertical soil pipe
opening upward into the air above the roof, if there be traps on several floors, one
above the other, and the upper one for instance be discharged, and the vertical
soil pipe into which it discharges be of the same size as the trap, the body of water, &c.,
descends in a substantially solid mass compressing the sewer gas in the pipe below
or ahead and causing more or less of such sewer gas (if the compression be
sufficient) to force itself through the adjacent traps below into the rooms. This
result would also follow to some extent even where the traps are provided with
air pipe branches into the soil pipe, and in addition such branches would be in a
measure receptacles for a portion of the solid matter, etc., descending from above.
them, and would thus be liable in time to become choked up and closed. To
obviate these various defects is the object of my Invention which comprises a sewer
gas pipe separate and distinct from the soil pipe and connected and arranged in
suitable relation with the traps to afford at all times an unimpeded vent or escape
for the sewer-gas that would otherwise accumulate at the traps. To better and.
more clearly explain the nature of this Invention, reference is made to the annexed
Drawings which form part of this Specification, and in which Figure 1 represents
an elevation partly in section of a portion of a dwelling provided with sewer pipe
connections constructed in accordance with this Invention, A representing a
closet bowl on the upper floor, B a wash basin on the next floor below, and C a
sink on the lower floor, each vessel or receptacle being connected by a trap a, b, c,
respectively, with the soil or discharge pipe D which empties into the sewer E.
Near the soil or discharge pipe D runs a separate gas pipe G connected with the
traps a, b, c, preferably by branches g at the outlets proper of the traps (or the
bigbest points of the latter just above the water seal and between it and the end of
the trap where the latter empties into the soil pipe); these branches g pass upward
from the traps so that no solid matter will enter them but will be carried off into
the soil pipe. The gas pipe G should be carried above the roof with its open end
preferably alongside of the top of the chimney K, so that the heated air rising from
the chimney flue may aid in carrying off the sewer gas as it escapes from the top
of the gas pipe G. The gas pipe G may be closed at the bottom or, as shown in.
Fig. 1, it may be open at the bottom near the ground to create an upward
circulation through it. Or it may start from the lower trap, in the manner shown
in Fig. 2, or from the soil pipe, as shown in Fig. 3, or from the horizontal portion
of the soil pipe as shown in Fig. 4. And instead of connecting the traps with the

page_text: gas pipe in the manner shown in Figs. 1 and 2, the branches may be run into the
gas pipe from that portion of the soil pipe at the end of each trap, in like manner
as shown in Fig. 3, but it is much preferable to connect the branches as first shown
at the outlets proper of the traps, because such connection affords a more certain
and effective vent for the sewer gas at all times, and is a surer preventive of the
syphoning of the traps as well. It is evident that the traps, not only of water
closets, wash basins, and sinks, but also of bath tubs and other like receptacles can
be connected to the gas pipe. It will also be understood that the gas pipe need be
kept separate from the soil pipe only as high as the uppermost trap with which it
is connected, and may enter the soil pipe above that trap provided the soil pipe be
then carried upward and be open above the roof. Having thus described the nature
of the Invention of my foreign correspondent and the manner in which the same
may be practically employed. What I claim and desire to secure by Letters
Patent is,
First. In sewer pipe connections, a gas pipe separate from the soil or discharge
pipe, and connected and arranged in suitable relation with the traps, to afford an
uninterrupted vent or escape at the traps for the sewer gas there accumulating,
substantially as herein set forth.
Second. In sewer pipe connections a gas pipe separate from the soil or discharge
pipe, and connected by branches to the traps at the outlets proper of the latter, and
arranged to carry off the sewer gas entering the traps, substantially as herein set
forth.
Third. The combination of the soil or discharge pipe, one or more traps entering
and discharging into said soil pipe, and a gas pipe, separate from the soil pipe and
connected independently of the latter with the traps at the tops or upper parts of
the trap outlets, substantially as and for the purposes herein set forth.
In witness whereof, I, the said Philip Syng Justice, have hereunto set my
hand and seal, this Second day of March, in the year of our Lord 1880.
