PROVISIONAL SPECIFICATION.
Improvements in Gully Traps.
ARTHUR BLAND, of Lilac Street, Leemount, Halifax in the County of York,
Builder do hereby declare the nature of this invention to be as follows:-
Heretofore in the construction of gully traps, for dwellings and public buildings,
placed outside the building, there has been but one trap, connecting with the drain or
sewer, which does not effectually prevent the foul and vitiated air from passing into
the building, whereas my invention consists of a gully with two traps the water or
refuse from the watercloset or sink passing by pipe to the first trap, thence to the
ordinary gully trap, both being by preference connected and form one piece, the one
described is intended to be earthenware, with a cast iron grate covering the two.
Or the gully trap may be made entirely of cast iron, the partition forming the first
trap is covered by one of the ribs of the grate, thus forming two perfect traps. The
grate covers the two traps whilst the openings therein allow free ventilation to both
to prevent the grate being put in the wrong position the extended rib projects into
recesses formed in the gully trap.

COMPLETE SPECIFICATION.
Improvements in Gully Traps.
ARTHUR BLAND of Lilac Street, Leemount Halifax in the County of York Builder
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 :-
Heretofore in the construction of gully traps for dwellings and public buildings
placed outside the building. The traps connecting with the drain or sewer do not
effectually prevent the foul and vitiated air from passing into the building. Whereas
my invention consists of a gully with two traps constructed so as to make a perfect
double trap with one grate covering the whole thus allowing the vitiated air to pass
into the open air instead of into the building. In order that the nature of this
invention may be fully understood, I have hereunto annexed one sheet of drawings
in which Fig. 1 is a sectional elevation through line A B of Fig. 2 drawn to scale,
Fig. 2 is plan of trap shewing grate in position.
1-2 forms the double trap the water or refuse from water closet or sink passing
by pipe 3 to the first trap 1 thence to the ordinary gully trap 2 both being by preference
connected and form one piece, the one illustrated and described is intended to be
earthenware with a cast iron grate 4 covering the two or the gully trap may be made
entirely of cast iron the partition 5 forming the first trap is covered by one of the
ribs 6 of the grate 4 thus forming two perfect traps. The grate is reversable and
cannot be put in the wrong position, the rib 6 being the same distance from end of
grate as one of the corresponding ribs.
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
A double gully trap substantially as herein described and illustrated.
