Year: 1888

page_text: I, GLORGE HARVEY, of Thorncliffe Lane, Chapeltown, near Sheffield, Iron Works
Manager, do hereby declare the nature of this invention to be as follows
-
My invention relates to stench traps ordinarily used upon pipes carrying away waste
water or other fluid, to drains or other places of discharge, in which traps a water
seal is provided which whilst it allows the water or other liquid to pass away, prevents
the return of air or deleterious gases through the trap
For this purpose I use a double trap, consisting of an upper basin or cup, covered
by a perforated plate preferably loose having attached to or formed upon it below an
inverted bell or cup fitting freely over the upper open end of a central waste or
discharge pipe which rises nearly to the top of the bell, so as to form a trap in the
usual way
Below the basın I attach or form a second cup or basın into which the end of the
waste or discharge pipe described dips nearly to the bottom, the upper edge of the cup
or basın being open but connected to the bottom of the upper basın by a sufficient
number of arms or branches, leaving spaces or openings between them through which
the water rising in the lower basin overflows and passes away
the
In the case of sinks, and in other cases of the like kind, I make an outer cup
upper edge of which is soldered or otherwise attached to the bottom of the upper basın
and to the bottom of which the waste pipe carrying away the water or other
liquid is connected, this outer cup leaving sufficient space between itself and the
lower basın for the water flowing over the upper edge or openings of the latter to
pass freely away
The improved trap may be of any desired dimensions and shape
By my invention, a double security against the return of ail or gases is obtained,
the apparatus constituting two distinct traps, whilst it is very simple, cheap, and
easily fixed and kept clean

I, GLORGE HARVEY, of Thorncliffe Lane, Chapeltown, near Sheffield, Engineer, do
hereby declare the nature of this invention and in what minner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, and accompanying drawing, (that is to say)
-
My invention relates to stench traps ordinarily used upon pipes carrying away waste
witer or other fluid, to drains or other places of discharge, in which traps a water seal
is provided which whilst it allows the water or other liquid to pass away, prevents the
return of air or deleterious gases through the trap
For this purpose I use a double trap, composed of an upper trap consisting of a
basın or cup, covered by a perforated plate preferably loose, having attached to or
formed upon it below an inverted bell or cup fitting freely over the upper open end of
a central waste or discharge pipe which rises nearly to the top of the bell, so as to
form a trap in the usual way
Or, the lower end of the cup below the grating may be open and dip into a basın
below
1
Below the upper basın I attach or form a second cup or basın into which the end of
the waste or discharge pipe described dips nearly to the bottom, the upper edge of the
cup or basın being open but connected to the bottom of the upper basin by a sufficient
number of arms or branches, leaving spaces or openings between them through which
the water rising in the lower basın overflows and passes-away --Or, the-basin into
which the open ended cup below the grating dips may have formed below it an inverted
cup having perforations or openings round its lower edge This lower edge rests upon
the bottom of the outer trap, the waste water pipe from the bottom of the latter rising
into and nearly to the top of the lower inverted cup
The upper basın, into which the open end of the cup below the grating dips, and the
lower inverted cup, into which the water pipe rises, are preferably formed in one piece
and are made moveable so that they can be readily lifted out for the purpose of
cleaning
"
In the case of sinks, and in other cases of the hike kind, I mike in the arrangement
first described an outer cup the upper edge of which is soldered or otherwise attached
to the bottom of the upper basin and to the bottom of which the waste pipe carrying
way the water or other liquid is connected, this outer cup leaving sufficient space
between itself and the lower basın for the water flowing over the upper edge or
opening of the latter to pass freely away The improved trap may be of any desired
dimensions ind shape
In the accompanying drawing which is in illustration of my invention, figure 1 is a
perspective view, and figure 2 a vertical section through A, B, of the improved double
trap
a is the open ended cup below the grating b and c 1 the basin into which
it dips

page_text: d is the bottom of the basin, and e is the inverted cup below it having openings
or perforations round its lower edge which rests upon the bottom of the trap g
from which the waste pipe frises into the inverted cup e A pipe to convey
away the waste water is attached to the pipe at h
The part c, d, and e being in a separate piece can be readily removed when
desired It may fit in guides upon the bottom in order to adjust it in proper
position
By my invention, a double security against the return of air or gases is obtained, the
apparatus constituting two distinct traps, whilst it is very simple, cheap, and easily
fixed and kept clean
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
-
In a stench trap, the combination of an upper or dirt trap a, c, with a lower trape,f,
substantially as and for the purpose described and shown
