Improvements in Gulley Traps.
I, RALPH GREENWOOD, of Marsden House, Haslingden, in the County of
Lancaster, Auctioneer, do hereby declare the nature of this invention to be as
follows:
My invention relates to gully traps for slopstones, baths, lavatories and the like,
also applicable to yard and street drains, and the chief objects of my invention are.
to trap noxious gases and so prevent bad smells and also to enable any dirt and
other sediment settling in the gully trap to be readily removed.
In applying my improvements to a gully trap for the inside of a dwelling or
building I employ a cylinder or casing closed at the bottom and arranged to be
secured at its upper end to the slopstone or other outlet for water which is protected
by a grating as usual.
In some cases the cylinder may be formed in one piece with the earthenware or
other stopstone.
From the top and inside of this cylinder is suspended a conical or other shaped
vessel, also closed at the bottom and divided by a partition which extends. from
near the top to within a short distance of the bottom; this partition, which is
closed at the top and open at the bottom, forms a trap and has an opening near
the top under the partition into the large cylinder, from which there is an opening
a short distance from the bottom, and connected preferably by an S pipe or passage
which forms a second trap to the waste pipe by which the water from the slopstone
or other place escapes to the drain.
By this arrangement any solid matter which passes through the grating and
settles in the conical vessel can be readily removed by lifting out and emptying the
conical vessel. If any deposit should settle in the outer cylinder it can be cleaned
out from the top.
In making a yard or other similar outside gulley trap according to my invention,
I take a cylinder or other suitably shaped receptacle formed of sheet iron, earthen-
ware, or other suitable material, and fit this into the ordinary vertical pipe of the
gulley trap. This receptacle is open above to receive water from the yard, and
closed at the bottom and a partition similar to that already described is fitted in or
formed with the receptacle and has an outlet placed under the partition and near
its closed top which conducts the waste water to the drain while the sediment.
deposited can be readily removed by lifting out and emptying the receptacle.
. I
For road or street purposes I make the apparatus just as described but of a
more substantial character and fit it below a grating.so that the receptacle can be
lifted by suitable tackle and emptied into a cart, thus avoiding the necessity for
the use of shovele or other implements to clear out the deposit from the pipe
trap below the street grating.

I, RALPH GREENWOOD, of Marsden House, Haslingden, in the County of
Lancaster, Auctioneer, 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:-
My invention relates to gulley traps for slopstones, baths, lavatories, and the
like, also applicable to yard and street drains, and the chief objects of my invention.
are to trap uoxious gases and so prevent bad smells and also to enable any dirt and
other sediinent settling in the gulley trap to be readily removed.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and. letters marked thereon.
Fig. 1 is a sectional elevation of a gully trap for the inside of a dwelling-mado.
according to my invention.
Fig. 2 is a similar view of an outside gulley trap,
Fig. 3 is a modification of Fig. 2, .
Fig. 4 is a gulley trap adapted for street and road purposes, and
Figs. 5 and 6 are two views of my improved gulley trap fitted direct into the
square mouth of a round drain pipe.
Similar letters refer to similar parts throughout the several views.
In Fig. 1, a represents a slopstone or other outlet for water which is protected
as usual with a wire or other grid; from a hole in the slopstone a is. suspended or
secured a circular or other vessel b.the bottom of which is closed, a short distance
from the bottom is an opening preferably connected by an S pipe c to a drain
or outlet. From, the top and inside of the cylinder bis suspended a conical or
other shaped vessel d also closed at the bottom and divided by a partition d' which
extends from near the top to within a short distance of the bottom; this vessel is.
provided with an opening near the top under the partition into the cylinder b
and thus forms a trap..
When dirty or other water is emptied on to the slopstone it finds its way into
the vessel d and when it rises high enough it escapes through the opening into
the cylinder and passes away to the drain through the opening into the S pipe
which formis.a second trap.
C
By this arrangement any solid matter which passes through the grating and
settles in the bottom of. the vessel cau be readily removed by lifting out and
emptying the vessol d and if any. deposit should settle in the outer cylinder b it can
be cleaned out from the top when the vessel dis removed. The vesselsib and d can
be made of galvanized sheet metal or of any suitable material.
In Figs. 2, 3, 4 and 5: my improved trap d. is shown applied to the ordinary
vertical pipe of an outside gulley. trap bi in Fig. 2 the improved trap d'is.circular
with a round bottom; in Fig. 3 the trap is rectangular; these traps are fitted
in outer casings 6 from which the water passes through an S-pipe to the drain and
they are made of any suitable material and cau be lifted by means of a handle k,'
shown in Fig. 2 only, for the purpose of emptying and cleaning.
Fig. 4 is an apparatus of a larger and more substantial character; in this, case
the trap d is provided on two opposite sides with eyes d³ so that after removing the
grating git cau be lifted by suitable tackle and the contents emptied into a cart
thus avoiding the necessity for the use of shovels, ladles, or other implements in
the ordinary way to clear out the deposit passing through the street grating and
settling in the bottom of the trap.
Fig. 5 represents a cheap form of trap d for cottage and other property in a
which the trap is fitted into the mouth of en ordinary vertical

page_text: As an extra preventative against the rise of sewer gas prefer to bend over the
upper edges of the traps d, as shown at Fig. 3, and allow these edges to rest in
grooves e in the block which supports the trap.
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 :-
1. The herein described improvements in gulley traps consisting in the use and
application of a vessel such as the vessel d closed at the bottom and provided with
an outlet and a partition closed at the top and covering the outlet, such partition
extending to within a short distance from the bottom and arranged so that any
liquid which enters the vessel must rise under the partition before it can escape
through the outlet whereby the return passage of noxious gases is trapped.
2. The several constructions combinations and arrangements of parts embodying
my improvements in gulley traps substantially as herein described and as
illustrated.
