PROVISIONAL SPECIFICATION.
Improved Self-cleansing Sanitary Gulley.
HORACE WILLIAM SWAIN Rock House Stapleton Road Bristol Jeweller and
Fancy Dealer do hereby declare the nature of this invention to be as follows:-
A gulley to carry off surface water, so constructed as to be fixed in any direction
to suit the position of the drain, with an ordinary outlet on the one side to emoty
into the drain, whilst on the opposite side, there is a flush-pipe with an inlet
connected at the extreme base of the gulley. Into the opening or top of the flush-
pipe, the downpipe conveying the water from the roof of the house will empty
itself, or through the aforesaid flush-pipe water can be forced and so wash all
sediment and dirt from the gulley; thus keeping it perfectly clear and pure.
Dated this 29th day of May 1896.
HORACE WILLIAM SWAIN.
HORACE WILLIAM SWAIN Rock House Stapleton Road Bristol Jeweller,
Fancy Dealer &c. do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This gulley is made either of clay or cast iron. It is square in shape and is
made to receive surface water. The square opening in the top is covered in by an
iron or clay cover with slots or holes in it to allow the surface water to pass
through into the gulley. On one side of the gulley is the outlet pipe (E) which is
connected to and conveys the water from the gulley to the drain, this gulley has a
water seal of about two or two and a half inches. On the opposite side and right
facing the outlet pipe is a pipe (a) with a socket; this pipe is on a level with the
top surface of the galley and extends down the full length of the side entering the
gulley at the base C with a mouthpiece opening shaped to reach the whole width of
the bottom of the gulley.
The socket of the pipe a which may be covered in with a grating if desired, is
made to take two flushing pipcs.
1st. For carrying off the waste water from the sink or slopstone of the house.
2nd. For carrying off the rain water which is usually conveyed from the roof by
means of a rain water pipe attached to the side of the house. In cases where there
are bathrooms or lavatories an extra pipe is required and to meet this requirement
an extra junction pipe b is branched into the aforenamed flushing pipe a as shown
in the drawing. The use of this branch would be optional according to the
requirements of the house.
Owing to the flushing pipe a opening into the gulley at the bottom of the trap c,
and the outlet d being also at the bottom of the trap, the bottom is constantly and

page_text: thoroughly cleansed by the flushing of the waste water from the sink or slopstone,
and the rain water from the roof of the house, and so no foul gas can arise from
sediment which would otherwise settle there.
There is no possibility of sewer gas escaping through the flushing pipes, as the
water in the gulley will find its level through the opening C, thus causing a perfect
-seal.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
