PROVISIONAL SPECIFICATION.
Improvements in Traps for Waste Pipes and the like.
I, CHARLES STOWE, of Lane End House, Stanningley, near Leeds, in the County
of York, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in traps such as S or P traps for waste
pipes and the like, and its object is to keep the waste pipe, that is to say, the
pipe that is tapped from being choked or blocked.
For this purpose I fit a grate or grid in the passage through the trap preferably
about mid-way between the two bends.
To facilitate this the trap may be made in two pieces and the grate or grid may
be fixed at or close to the joint. The trap may be made in cast iron and the two
parts may be connected by a flange joint packed with suitable packing.
The ends of the trap may be formed with screw threads to connect them to the
pipe, or short pieces of pipe may be screwed in to which lead pipe may be
connected by a plumber's joint.
I find there is considerable advantage in making the tap in two pieces although
a grate or grid may not be fitted in it.
Dated this 14th day of December, 1896.

Improvements in Traps for Waste Pipes and the like.
I, CHARLES STOWE, of Lane End House, Stanningley, near Leeds, in the County
of York, Mechanic, 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 traps such as "S" or "P" traps for
waste pipes and the like, and its object is to keep the waste pipe, that is to say:
the pipe that is trapped from being choked or blocked.
For this purpose I fit a grate or grid in the passage through the trap preferably
about midway between the two bends.
The trap is made in two pieces and the grate or grid may be fixed at or close
to the joint. The trap may he made in cast iron and the two parts may be
connected by a flange joint packed with a suitable packing.
To more fully describe my invention reference is made to the accompanying
021

page_text: sheet of drawings forming a part of this specification, in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1 represents an elevation of an "S" trap made in accordance with my
invention.
Figure 2 is a plan view of the same and Figure 3 is a sectional view on the
broken line a, b.
Figure 4 is a separate elevation of half the trap and Figure 5 is a plan view of
the same.
Figure 6 is a separate plan view of the grate.
The trap is made in two pieces A and B formed with flanges A and B³. The
two flanges are connected together by the bolts C, C. Packing D is introduced
between the flanges and to reduce the liability of the passage E being choked I
also introduce the grating F which is fixed with the packing between the flanges.
The ends of the trap may be formed with screw threads G to connect them to
the pipe, or short pieces of pipe may be screwed in to which lead pipe may be
connected by a plumber's joint.
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:
1. A trap formed in two pieces connected together substantially as herein shown
and described and illustrated in the accompanying drawings.
2. A trap formed in two pieces and connected together with a grating between
them, substantially as herein shown and described and illustrated in the
accompanying drawings.
