Improvements in House and other Drains.
EDWARD TURNER, of 36 Saint James Road in the City of Liverpool, Painter, etc.,
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 consist of an improved trap wherein the parts are all easy of access
for cleansing purposes and so constructed that, even while the process of cleansing
is taking place, the gases from the sewer are trapped, or held back, and so
prevented from injuring the person who may be so engaged.
are side
I effect this by constructing traps in the manner hereinafter described, reference
being had to the accompanying drawings wherein Figures 1, 2, and
sectional elevations of modified forms of my aforesaid improved trap and Figure 4
is an end sectional elevation of the aforesaid trap, the lettering in each drawing
being the same where parts are identical.
Figure 1 is such a trap formed of iron, earthenware, or other suitable material in
which A is the outer casing and B3 the inner division forming the dirt trap C
and 6 6¹ extension of the said inner division B forming the water sealing dip plug
well and inspection opening d communicating directly with the sewer from the
outer mouth, of the trap E, and closed by the dip plug F the sides fof which, dip-plug,
enter into the dip plug well e and the centre plug into the inspection opening d
so water sealing the whole; and as this said dip plug is only intended to be removed
in the event of a stoppage taking place which it is found impossible to otherwise
clear I further seal the joint by means of a wrapping of rag, or other suitable
material, round the centre plug of the dip plug afore mentioned tying the said
wrapping thereon into a groove, or grooves, provided thereon for the purpose; or
by the use of an india rubber or other washer suitably attached to the said centre
plug. The outer mouth E of the trap is closed by a hinged grating G to which is
hinged a second grating H which hangs vertically across the inner mouth J to
intercept any floating matter.
Figure 2 is a modification of Figure 1, wherein the dip plug is varied in
form and held firmly in place by the lever L secured by cotter pins at m m².
Figure 3 is a further modification wherein the soil pipe from a closet is led into
the passage, or space, N between the outer casing A and the inner division B as
shown at 0: In this case (Figure 3) the vertical grating is not required and
in order to avoid smell from the closet soil pipe the inner mouth J is itself
trapped by the division P the edge p of which is carried well below the water
level in the dirt trap. In this pattern either form of dip plug may be used.
A description of the action of Figure 1, with slight modification will serve to
describe the action of all the forms of the afore-mentioned trap, and I here give
such a description and the advantages attendant on the use of iny aforesaid trap:-
On water, etc. being emptied on to the mouth of the trap E it falls through the
grating G into the dirt trap C which it fills (at the same time filling the dip plug
well c and water sealing the dip-plug Fff) and flowing through the vertical
grating H passes over the bridge K of the dirt trap C and through the inner
mouth J into the passage N under the dirt trap C and thence into the sewer at S.
I claim as advantages :―
That the trap is easy to clean as the parts are very accessible.
That while being cleaned (in the usual manner by flushing) gases cannot escape
from the sewer

page_text: That by the use of traps constructed according to Figure 3 there will be a
saving in the quantity of pipes used.
That the joint of the trap to the sewer can be reached on the inside through
the dip plug inspection opening and that therefore a good smooth joint can be
made.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1st. The use and manufacture of traps such as are hereinbefore described and
shown in the accompanying drawings.
2nd. The use in traps (such as are hereinbefore described) of a second grating
hinged to the usual grating over the mouth of the trap and hanging over the
inner mouth of the trap substantially as and for the purposes herein before
described.
3rd. The use in traps (such as are hereinbefore described) of a plug, such as is
hereinbefore described and shown, to close an "inspection opening from the
interior of the trap to the sewer in the manner and for the purposes hereinbefore
described and shown.
4th. The use in traps (such as are hereinbefore described) of an interior
inspection opening such as is hereinbefore described and shown substantially as and
for the purposes described.
Dated this Thirtieth day of January 1894.
