A SEWER GAS PREVENTER AND SEWAGE COLLECTOR
Year: 1884

page_text: I, JOHN HART YEO of Furzeham, Brixham in the County of Devon, Shipowner,
do hereby declare the nature of my Invention for A SEWER GAS PREVENTER AND
SEWAGE COLLECTOR, to be as follows:-
This Invention refers to an apparatus for preventing the entrance of sewer gas
into houses and collecting sewage, A shaft is sunk cutting the pipe which connects
the house with the main sewer. Into this an iron chamber is lowered having holes
corresponding to the openings in the drain pipe. The sewage collects in this and
is drawn up and carted off. When the chamber is full the sewage traps the gas.

page_text: I, JOHN HART YEO of Furzeham Brixham Devon Shipowner do hereby declare
the nature of my Invention for A SEWER GAS PREVENTER AND SEWAGE COLLECTOR
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My plan is to sink a shaft-say-3 feet in diameter down on the drain pipe
which connects the house with the main sewer and when-say-3 feet below the
pipe to take out 3 feet of this pipe (thus completely severing the connection
between the house & main sewer) and fit in the iron shaft (a) which encloses iron
chamber (b) bringing the ends of the pipe (c) into the holes (d). The hole opposite
the one nearest the house would be elongated so as to meet the difference of fall in
the drain pipe according to circumstances and when necessary the slide (e) would
be used to partly cover the hole on the outfall side so that the liquid sewage should
always cover this hole and prevent the escape of gas from the main sewer.
Should however any portion in the form of air bubbles or otherwise force its
way into the chamber it could not possibly get into the house but would rise up
the shaft and become diffused in the atmosphere.
Supposing the connection with the main sewer to be in the front of the house
the shaft would be in or near the gutter the cover of this shaft would be scored as
shown in Drawing (marked "Plan") to prevent horses &c. slipping on it. I ask
the right however to place fix or connect this apparatus in or with any part of the
drainage most suitable for it.
The collection of the sewage would be done by lifting the chamber-first closing
the holes with the slides and closing the lid-these chambers would be placed in
the collecting carts and empty chambers put in their places so that no smell be
caused by emptying.
The shafts of the carts would be interchangeable and any number of carts could
be linked together one of which would have a small portable crane or purchase for
lifting the chambers.
The noncollection of the sewage would in nowise detract from the immense
value of this Invention as a sewer gas preventer: it is however a matter of the
utmost importance that this Invention renders the collection of the sewage &
comparatively easy matter.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The method and apparatus for preventing the entrance of sewer-gas into houses
and collecting sewage consisting of a shaft sunk to cut the pipe leading to the
sewer into which shaft an iron chamber is lowered substantially as hereinbefore
described.
