Improvements in Water Closet Bowls.
I, HAMILTON AUGUSTUS JUKES, of Winnipeg, in the Province of Manitoba,
Canada, Gentleman, 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 improvements in water closet bowls, and more
particularly to the ventilation thereof, and it has for its object to provide a water
closet bowl embodying means for conducting a continuous current of air from a
point adjacent to the floor upon which the bowl is placed, up to and around the
inside of the bowl and out through a suitable vent pipe whereby all foul odours or
gases will be conducted from the bowl whether the lid or cover of the same is
opened or closed.
Other objects and advantages of the invention will appear from the following
description and claims when taken in connection with the accompanying drawings
in which:
Fig. 1 is a vertical section of a water closet bowl embodying my invention.
Fig. 2 is a horizontal section taken in the plane indicated by line x-x of
Fig. 1, and
Fig. 3 is a vertical diametrical section of a slightly modified construction of
bowl.
Referring by letter to said drawings, and more particularly to Figs. 1 and 2
thereof, A. indicates a water closet bowl, which may be of any approved general
construction, and B, C, respectively indicate the water inlet or flushing pipe and
the drain pipe thereof. The bowl A may be formed from porcelain, iron or other
suitable material, and it is provided preferably upon its forward side with a conduit
or tube D, which extends to a point adjacent to the floor upon which the bowl is placed
and bas its lower end open for a purpose presently described. This conduit or
tube D extends upwardly to a point adjacent to the upper edge of the bowl, where
it merges into a curvilinear conduit or tube E which extends partly around the
inner side of the bowl and has its ends open, as shown.
F indicates a vent pipe which leads from the upper portion of the bowl A,
preferably at a point diametrically opposite to the pipe or conduit D, and serves
to conduct the foul odours or gas from the bowl. This pipe F may discharge into
the usual ventilating flue, or it may be carried through the wall or roof of the room
into the open air, as desired.
It is obvious from the foregoing description taken in connection with the
drawing, that when the lid or cover of the closet is closed a continuous current of
air will take through the conduits D and E, and the bowl and up and out through
the vent pipe F.
By reason of the conduit E being arranged in the manner shown and described,
with respect to the vent pipe F it will be seen that a space is afforded between
said conduit and pipe for the creation of a suction through the medium of which
the foul odour and gas will be drawn up and into the pipe F and the air in the
bowl will be rendered pure and wholesome.
In Fig. 3 of the drawing I have illustrated a construction which is similar to
that shown in Figs. 1 and 2 with the exception that an open conduit E' which
extends entirely around the bowl is employed instead of the closed conduit E
illustrated in said Figs. 1 and 2.
This open conduit E¹ which communicates with the conduit D and pipe F, is formed
by the depending annular flange a, and by the provision of the said conduit it will

page_text: be seen that a great suction space is afforded for the reception of the odour and gas
which are carried by the current of air into and through the pipe F.
It will be readily seen from the foregoing description that I have provided a
simple water closet bowl which will at all times be pure and wholesome and one
that may be manufactured at a cost very little greater than the cost of the
ordinary bowl.
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
1. In a water closet bowl, the combination of a vent pipe F communicating with
the upper portion of the bowl the conduit D arranged at a point remote from the
vent pipe, the said conduit D leading from a point adjacent to the floor upon which
the bowl is placed and having its lower end open, substantially as and for the
purpose set forth.
2. In a water closet bowl, the combination with the bowl, of a vent pipe F
communicating with the upper portion thereof, the conduit D arranged at a point
remote from the vent pipe and leading from a point adjacent to the floor upon
which the bowl is placed, and a conduit arranged upon the inside of the bowl
adjacent to the upper edge thereof and communicating with the conduit D and the
interior of the bowl, substantially as specified.
3. In a water closet bowl, the combination of the bowl, the vent pipe F
communicating with the upper portion of the bowl, the conduit D arranged at a
point remote from the vent pipe and leading from a point adjacent to the floor
upon which the powl is placed, and the closed pipe or conduit E connected at an
intermediate point in its length to the upper end of the conduit D and having its
open end resting contiguous to the vent pipe, substantially as specified.
4. In a water closet bowl, the combination of the bowl, the vent pipe F
communicating with the upper portion of the bowl, the conduit D arranged at a point
remote from the vent pipe and leading from a point adjacent to the floor upon
which the bowl is placed, and the open conduit E' extending entirely around the
bowl and connecting with the conduit D and the vent pipe F, all substantially as
and for the purpose specified.
