Improvement in Traps for Drain-pipes, Sewers, Gullies, and similar
Appliances.
I, ROBERT ALEXANDER LOWE, Builder and Decorator, of Lower Camden,
Chislehurst, in the County of Kent, do hereby declare the nature of this invention
to be as follows:-
This invention relates primarily to the traps of earthenware drain pipes having
an egg-shaped cross section, but is applicable also to gully-traps, closet-traps
and sewer-traps.
Egg-shaped drain pipes are frequently preferred to circular pipes, because they
render the accumulation of solid refuse more difficult, and are self-cleansing in
a higher degree, than drain pipes of uniformly round section.
The object of my invention is, to obtain the same advantages also for seal-
traps or syphon-traps, which are usually made circular in cross section, except
in the case of water closets, where the deepest part or pan is frequently made
with slanting sides, while the outlet is circular.
I make the cross section of the trap. measured at a right angle to the flow
of the water, egg-shaped from one end of the trap to the other, or at least from
the deepest part, or the sole of the pan to the outlet, so that the outlet may be
connected easily and immediately with an egg-shaped pipe.
Such traps may be made of earthenware, metal, or other suitable material.
Dated this 23rd day of November 1897.
