I, WILLIAM JOSEPH BALK, plumber, of Tennant Street, Bradford, Yorkshire, do
hereby declare the nature of the said Invention, to be as follows:-
This Invention consists essentially in the construction of a combined trap and
gulley substantially in the manner hereinafter described.
Gullies or traps are at present most generally made in the form of a rectangular
box or receptacle provided with a spout jutting upwards from the lower part, the
solid refuse being deposited in the box in order that it may be removed, and the liquid
flowing into the drain. Upon removal of the solid matter, if the box is not again
supplied with water the gases escape from the main drain through the gulley. This
also occurs when the contained water is dissipated by evaporation, or is absorbed by
any adjacent solid matter, or by solid matter falling into the gulley.
The special object of the Invention is to obviate this disadvantage.
In accordance with the present improvements the gulley is made of a rectangular
box like form as usually, but it is made without the said spout and is formed in lieu
thereof with an opening adjacent to the top of the box and to which I attach another
rectangular or oblong box of somewhat smaller dimensions having a central partition
depending from the top to near the bottom into the liquid which overflows from the
gulley through the said top opening thereinto, and forming a trap therewith, and from
the end of which trap box the liquid overflows into the main drain.
The trap box is provided with an air tight cover which can be opened from the
surface in order to inspect and cleanse the box.

page_text: I, WILLIAM JOSEPH BALK, Plumber, of Tennant street, Bradford, Yorkshire, do
hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
This Invention consists in the construction of a combined trap and gulley sub-
stantially in the manner hereinafter described.
Gullies or traps are at present most generally made in the form of a rectangular box
or receptacle provided with a spout jutting upwards from the lower part, the solid
refuse being deposited in the box in order that it may be removed, and the liquid
flowing into the drain. Upon removal of the solid matter if the box is not again
supplied with water the gases escape from the main drain through the gulley. This
also occurs when the contained water is dissipated by evaporation, or is absorbed by
any adjacent solid matter or by solid matter falling into the gulley.
The special object of the present Invention is to obviate this disadvantage.
A combined trap and gulley constructed in accordance with the present improve-
ments is illustrated on the accompanying drawings in sectional elevation in Fig. 1,
and in plan view in Fig. 2.
In accordance with such improvements, the gulley, 3, (made of a rectangular
box-like form as usually, or of a cylindrical or like tubular form) is made without the
said spout and is formed in lieu thereof with an opening, 4, adjacent to the top of the
box. At such part of the box, I attach or form together therewith another rectangular
or oblong box or receptacle, 5, of somewhat smaller dimensions, the same having an
open top and a central partition, 6, depending therefrom to near the bottom of the
receptacle, 5, into the liquid which overflows from the gulley, 3, through the said top
opening, 4, thereinto, and forming a trap therewith, and from the end of which trap
box, 5, the liquid overflows through an opening, 7, into the main drain.
The top opening of the trap box, 5, is provided with an air-tight lid or cover, 8, also
fitting against the partition, 6, and which can be opened from the surface in order to
inspect and cleanse the box, 5.
The gulley, 3, is provided with a grating, 9, as usually.
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 construction of a combined trap and gulley substantially in the manner
herein before described.
