PROVISIONAL SPECIFICATION.
Improvements in Gulley and Stench Traps.
We, JOSEPH JOHNSON, Manufacturer, and SARAH JOHNSON, Married Woman,
both residing at 32, Wellington Road, Bilston, and ELIZABETH JONES, Married
Woman, residing at 9, High Street, Wolverhampton, all in the County of Stafford,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to gulley and stench traps, and consists in certain improve-
ments in their construction having for their object the simplification of the parts
and the power to better deal with storms than hitherto.
According to this invention the bottom of the gulley is formed into an S or P
trap to form a seal against the drain or sewer, and into this said trap are arranged
a number of branches or water-ways disposed at distances apart around the walls
of the gulley trap body, and whose mouths come at right angles to the said water-
ways and near the grid, lid, or cover of the gulley. The walls of the body of the
gulley trap are made to centrally support an open topped mud receiver, into which
the sewage waters first pass before entering the waterways and passages before
described to the drain, the same forming a precipitation tank for the solid matter
carried with the water. The bottom of this mud receiver is pierced with small
holes, so that the water may drain from the precipitated matter to the seal or trap.
The bottom of the gulley trap body, which is situated higher up than the S or P
trap in the gulley and underneath the bottom of the mud receiver, is removable
in order to obtain access to the S or P trap should it be necessary, but the said
removable bottom is under the water line and is sealed; the nose or outlet from
the trap or seal being higher than the removable bottom of the gulley's body.
The waterways or branches conduct the sewage water as it overflows the sides
of the mud receiver to the S or P trap and gives it a straight fall thereinto, and,
in consequence of the water being fed at three or more points, it forms a kind of
whirlpool in the seal, which must of necessity carry all the sewage to the drain
and keep the seal or trap always well flushed.
In gullies for street and yard purposes where a relief passage for the sewage is
provided in case the grid-lid becomes stopped with rubbish, one of the inlets to
the vertical branches would be formed within the side or angle-plate and of a
larger area than the others so that it would take away the water at a higher level
than the grating-like lid and prevent a stoppage.

We, JOSEPH JOHNSON, Manufacturer, and SARAH JOHNSON, Married Woman,
both residing at 32, Wellington Road, Bilston, and ELIZABETH JONES, Married
Woman, residing at 9, High Street, Wolverhampton, all in the County of Stafford,
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 follow-
ing statement ;-
This invention relates to guiley and stench traps and consists in certain improve-
ments in their construction which have for their object the simplification of the
parts, the better flushing of the seals, and greater power to deal with storms than
hitherto.
The said improvements are shown applied to two forms of gulley traps in the
accompanying sheet of drawings, the one form having one working way and
being fitted with a weir or overtlow, and the other form being shown with three
working ways and without an overflow or weir. The gulley trap with the one
working way is shown in longitudinal section in Fig. 1 and in transverse vertical
section in Fig. 2, while the other gulley trap with three working ways is shown in
vertical section in Fig. 3 and in horizontal section in Fig. 4.
The invention will now be described in connection with the said figs., refer-
ence letters being used to indicate the different parts.
The bottom of the gulley body a is formed into a P trap to constitute the
gulley's seal against the drain or sewer, and into this trap are arranged a number
of branches or water-ways e disposed around the walls a of the gulley's body.
These waterways are the working ways of the gulley, and their mouths 2 come
at right angles to and near the gulley's grid lid or cover d. The walls a³ of the
body of the gulley are madę to centrally support an open top mud receiver e, into
which the sewage waters first pass before entering the waterways c, the said
receiver forming a precipitation tank for the solid matter carried in with the water.
The bottom of this mud receiver is pierced with small holes e², as also are the sides,
so that the water may drain from the precipitated matter.
The bottom a of the gulley's body a is situated at the top part or surface of
the P trap a² and is open at a to the said trap, so that access may be had to it
for cleaning by simply lifting out the mud receiver e. The open bottom a* is
arranged under the water line of the trap a² so that it is sealed against the sewer.
The mud receiver e rests upon a ledge a abounding the gulley's open bottom a*.
The waterways or branches c conduct the sewage water as it overflows the sides
of the mud receiver e to the trap a² and gives it a straight fall thereinto, so that
the seal water must be bodily disturbed and consequently kept on the move to the
drain. This is especially so in the form of gulley shown in Figs. 3 and 4, the
three working ways as the sewage falls into the trap at three different points and,
in all probability, at different forces, and causes a kind of whirlpool to be formed
in the said trap, which must, of necessity, keep the seal thoroughly cleansed.
In gullies for street and yard purposes, such as is shown in Figs. 1 and 2, a
relief passage or weir g is provided adjacent to the grid lid d for forming a water-
way to the gulley in case the said grid lid becomes stopped with rubbish. This
waterway leads from the surface of the grid lid through an angle plate to inlet
passages g³, which discharge onto the open top of the mud receiver e.
mouths of the waterways c are preferably made grating-like or fitted with bars h
as shown in Fig. 2 for the purpose of preventing straws, sticks, and such like
passing into the trap a².
The

page_text: The open bottom a¹ of the gulley's body may, if desired, be closed by a per-
forated removable lid and the trap a² thereof may be formed of an S construction.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is;-
First. In a gulley or stench trap, constructing the body thereof with a number of
waterways or passages such as c, which lead from the said body near the lid or
cover, and which discharge vertically into a trap disposed in the lowest part of the
said body, for the purpose substantially as described and set forth.
Second. In combination in a gulley or stench trap, a body part a fitted with
a trap a² at its lower extremity, and having an open bottom a which extends
below the waterline in the said trap, an open top mud receiver e located within
the said body and resting upon its bottom, and one or more waterways c which are
disposed vertically around the body a so as to lead from the top of the mud
receiver and to discharge into the trap a³, which latter forms a seal to the gulley,
substantially as described and set forth.
Third. In combination in a gulley or stench trap, a body part a fitted with a
trap a at its lower extremity, and having an open bottom a extending into the
said trap below the water line, a mud receiver e located within the said body and
resting upon its bottom a, and which has an open top and a per-
forated bottom, and a plurability of waterways c disposed vertically around
the body a so as to lead from the top of the mud receiver and to discharge
into the trap a², and which have their mouths preferably formed with bars h, sub-
stantially as described and set forth.
Fourth. In combination with the substance claimed in Claim 2 of parts g, g²
and g, forming a relief passage for the sewage if the grid lid becomes stopped,
substantially as described and set forth in connection with Figs. 1 and 2.
