COMPLETE SPECIFICATION.
Improved Waste Fittings with Loose Lip Basin Trap and Pipe for
Bath, Lavatory, or Sink.
DAVID HOWARTH 48 Egginton Street Rochdale Road Manchester Iron Moulder,
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:-
The loose lip and Basin Trap and pipe is intended to be fixed to Bath Lavatory
and Sink waste pipes, for the purpose of preventing sewer gas or foul air from the
drain entering the building.
To be made of iron, white metal or Brass.
Fig. 1 on the accompanying drawings represents a vertical section of the Trap to be
applied to a Bath or Lavatory waste pipe.
The circular Basin a. on the outer side of which are attached three vertical
feathers or strips of metal as at b. b. to keep it in position and allow a space all
round the Basin for the passage of water between it and the outer casing c. of the
Trap. The loose lip d. which screws into the top of the outer casing and the joint
made air tight by means of an india-rubber packing as at e. e, into the loose lip is
also fixed a grid as at f. also a countersunk plug marked 9.
The small pipe shewn at h. is intended to convey air from the outside of the
building to supply the waste pipe thus preventing the water contained in the
Basin a. being drawn out by suction that takes place during the passage of water
through the waste pipes. The trap is connected to the bath or lavatory by means of
the nut k.
Fig. 2. is a vertical section of the Trap and pipe intended to be applied to a sink
or slopstone. a. being the basin with feathers or strips of metal, b. b. on the outer
side as described above. The loose lip d. is screwed at e. e. into the top of the outer
casing c. c. of the trap and furnished with a grid as at f. The flange and socket joint
forming the connection between the vertical pipe i. and the elbow of the inclined

page_text: pipe m. is formed by a cast screw coupling h. h. with an india rubber packing j. j. At
the top of the inclined pipe is a moveable plug l. for the purpose of cleaning out the
pipe.
The trap is fixed to the sink by means of the nut at n. n.
Fig. 3. is a section on a smaller scale shewing the Trap and pipe in Fig. 2. fixed
in position-o. being the sink and p. the outer wall of the building.
.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed-I, declare that what
I claim is :
1. The improvement in the construction of the Trap and pipe.
2. The Basin and Lip being loose and separate.
3. The improvement in supplying the head of the waste pipe with air..
Doted this 18th day of September 1889.
