Improvements in Gulley or Stench Traps,
I, JOSEPH JOHNSON, of Wellington Road, Bilston, in the County of Stafford,
Managing Director, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in gulley or stench traps, and its
objects primarily are to provide improved means for outflow and overflow from
the mud container; also an improved communication with the sealing device for
cleansing &c. purposes; also improvements in the disposition of the grip and its
openings to facilitate the ready inflow of refuse; also a bolting device for retain-
ing the grid in its opened position.
According to this our invention we carry the hinge joint of the grid as far
back as possible, even to overhang the body of the trap, and in line with such
hinge pivot we provide grid perforations in addition to, or in extension of those
now in use. By this means we provide a ready escape for the water &c. in line
centrally with the gutter.
Further in the container we place at one or more corners, generally in two
opposite corners, a vertical down pipe whose upper edge is a little lower than the
depth of the container. At desired heights and positions in the walls of the con-
tainer outlet perforations are made, which form the usual means for escape of
water from the mud &c. which is gradually deposited in the container. Beneath
the container is a removable bottom having perforations through which the water
may drain. At corresponding corners to the beforementioned downpipes in the
container, openings are made in the removable bottom to agree therewith. Upon
the underside of this bottom is a seal flange which depends into the seal cavity
below, which is formed in the base of the trap, and in which is formed a central
outlet to the drain. This seal cavity is shaped somewhat towards the circular
form, or as near as convenient thereto, with communications therefrom to the
openings from the down pipes, in such a manner that when a rush of water
descends the down pipes-as an overflow &c. from the container-in entering the
seal it shall tend to cause a whirl in the seal, the agitation of which shall stir up
and drive over the outflow all heavy refuse which may have accumulated in such
seal cavity. Again. Upon the underside of the grid, I provide a sliding bolt
having a hook or the like at its one end. Agreeing with this bolt is a shoot
upon the frame of the trap, the whole being arranged in such a manner that
when the grid is opened to its full extent, the said bolt falls of its own weight
into its shoot and thus retains it in such opened position. When desiring to
close the grid, the bolt is withdrawn by means of its hooked &c. end, and the
grid lowered.

I, JOSEPH JOHNSON, of Wellington Road, Bilston, in the County of Stafford,
Managing Director, 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 invention relates to improvements in gulley or stench traps, and its

the mud container; also an improved communication with the sealing device for
cleansing &c. purposes.
In order to more clearly explain this my invention, I have appended hereunto
illustrative drawings upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part.
Fig. 1, is a view in sectional elevation (on line A-B Fig. 2) of a trap con-
structed according to this my invention.
Fig. 2, is a plan view of the trap.
Fig. 3, is a side sectional view of the invention on line C-D Fig. 1.
Fig. 4, is a plan view, and Fig. 5 a sectional view (on 'line E-F Fig. 4) in
detail, of the container.
Fig. 6, is a plan view of the removable bottom.
Fig. 7, is a sectional plan view of the bottom of the trap on line G-H Fig. 1,
with the removable bottom taken away.
12, is the trap or frame, upon and within which are carried the several remov-
able parts.
13, is the grid, which is jointwise carried upon the trap 12. This
hinge may be made of any suitable form, the chief object being to carry it as
far back as possible, as for instance as shown, in which the set back part 14, is
made to receive it, and provided with pivot pin 15, (shown in dotted lines) to
connect it with the ends 16 of the grid 13, thus permitting a hinge movement.
In line with this hinge joint I make the perforations 17, so as to form a ready
means of inflow in line directly with the lowest part of the gutter.
18, is the container, that is, a removable vessel which receives the flow, and
in which the mud or other heavy refuse deposits itself, while the thinner liquid
may pass through overflow holes 19, in its sides. It sometimes happens however
that during storms, a very rapid inflow takes place, in which the ordinary out-
lets 19, would be sufficient, and in which a considerable quantity of refuse may
escape with the water, and therefore I have made corner outlet pipes 20,-pre-
ferably in the two opposite corners.
little lower than the top of the container so that a rush of water would be quickly
The upper edge of these pipes is made a
discharged down the said pipes. This container as before intimated, may be
removed for the discharge of deposited refuse. This container is supported upon
a removable bottom 21, having perforations 22, through which any water lodging
thereon may pass.
At corresponding corners to the beforementioned down
pipes 20, in the container, openings 23 are also made in the bottom of the trap.
Upon the underside of this removable bottom is made the seal flange 24, which
depends into the cavity 25, which is formed in the bottom of the trap. In this
bottom is also formed the outlet 26, having the upstanding flange 27, to complete
the water seal. The cavity 25, has extensions 28, which come directly beneath
the down pipes 20, and openings 23. These said extensions 28, deliver them-
selves tangentially into the circularwise cavity 25, which causes the flow in its
rapid course to whirl around as indicated by arrows in the seal cavity, the
agitation of which shall stir up and drive out all heavy refuse which may have
accumulated in such cavity.

page_text: Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a gulley or stench trap, constructing the mud container 18, with overflow
pipe passage 19, communicating with the lower part of the trap, substantially
as set forth and shown.
2. In a gulley or stench trap, constructing the bottom with extensions 27,
tangential with the circular-wise central cavity 25, substantially as and for the
purposes specified.
3. In combination in a gulley or stench trap, a body 12, having cover 13, an
open top mud container 18, with discharge pipes 20, a perforated removable
bottom 21, having outlet openings 23, and seal flange 27, and seal cavity 25,
with extensions 27, all substantially as set forth and shown.
Dated this 30th day of May 1899.
