COMPLETE SPECIFICATION.
An Improved Ventilating Arm or Pipe for Water Closet Traps and
all other Traps.
I, EDWARD NAYLER, of 140, Lake Road, Landport, in the County of Hants,
Works Manager, 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 relates to water closet, and other traps.
The main object of my said invention is to provide a ventilating arm, or pipe of
improved form for water closet, and other traps.
will describe my invention as applied to a water closet trap.
In the accompanying drawings
Fig. 1, is a central sectional elevation of a water closet pan and trap.
Fig. 2, an outside elevation of same.
Like letters indicate corresponding parts throughout the drawings.
Various forms of ventilating arms, or pipes have been used for water closet pan
traps, for instance, according to one known form, a ventilating arm e, is provided
upon the crown of the trap d, placed as shewn in dotted lines (see Figs. 1, and 2,)
the result of this arrangement is, that in washing out the closet some of the water
and soil from the pan is discharged-to a greater or less extent, according to the
force with which it leaves the pan,-into the ventilating outlet c, at the base of the
arm e, until eventually a deposit of soil accumulates in the said outlet.
Another objection to the form and position of the ventilating arm e, is, that the
back draught blows down and through the arm direct on the water in the trap,
thereby rendering the water very liable to get frozen in severe weather.
According to my invention, with the view of obviating these objectional results
I place the ventilating arm upon the crown of the trap d, and make it of the form
as shewn at A, then the water and soil, while being discharged into the trap,
impinges against the projection b, and is thus diverted from the ventilating outlet f,
and falls into the water outlet g, of the trap d, without entering the ventilating
outlet f, at all.
Again, in water closets fitted with a ventilating arm, made according to my
invention, the back draught will not necessarily blow down direct upon the water
in trap-as it must when an arm is fitted of the form, and in the position shewn

page_text: at e-but the air will probably be discharged into the water outlet 9, of the
trap d; and my invention essentially consists in the form of the ventilating arm A,
including the projection b; and the position in which the arm is placed in relation
to the crown of the trap d, as, and for the purpose specified.
In the case of traps other than for water closets, the ventilating arm A, together
with the projection b, and other necessary attachments, or connections would, to
suit the circumstances be suitably disposed, although in a similar manner, as
bereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:
The improved ventilating arm A, for water closet, and the like, traps, con-
structed and arranged substantially as herein before described, and illustrated with
reference to the accompanying drawings, and operating as, and for the purposes
specified.
