closets and similar Arrangements.
I, ALFRED WELLINGTON SMITH of 17 St. Ann's Street, Manchester, in the County
of Lancaster, Architect, do hereby declare the nature of this Invention to be as
follows:-
It consists in improved apparatus whereby I am enabled to ventilate a portion of
the soil pipe, which has hitherto been unventilated, viz. the portion between the basin
trap and the upright or main soil pipe. To accomplish this I use an arrangement
whereby a valve placed in the side or other suitable part of the main soil pipe, and
which in its normal state closes the soil pipe is operated either by the pulling of the
handle of the watercloset, automatically, or by other arrangement, so as to open to
admit the passage of the soil and at the same time to close an outlet for the passage
of air to the portion of the soil pipe between the trap and the main soil pipe, I also
provide an air inlet for the purpose of allowing the wash of the water to create a
current of air which materially increases the ventilation. Immediately the soil has
passed, the valve closes preventing any noxious gases from entering the portion of
the soil pipe before mentioned and opening the air outlet and allowing all noxious
gases to escape they being replaced by fresh air from the inlet before mentioned.
It will be seen that the foregoing may be applied to various analogous purposes.

Improvements in Ventilating Apparatus for the Soilpipes of Water-
closets, and similar Arrangements.
I ALFRED WELLINGTON SMITH, of 17 St. Ann's Street, Manchester, in the County
of Lancaster, Architect, 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 :-
It consists in improved apparatus whereby I am enabled to ventilate a portion of
the soil pipe, which has hitherto been unventilated viz. :-the portion between the
basin trap, and the upright or main soil pipe.
To accomplish this, I use an arrangement whereby a valve placed at the side or
other suitable part of the main soil pipe, (and which in its normal state closes the
soil pipe,) is operated either by the pulling of the handle of the water closet, auto-
matically, or by other arrangement, so as to open to admit of the passage of the soil,
and at the same time to close an outlet which I provide for the passage of air from
the portion of soil pipe between the basin trap and main soil pipe to the open air. I
also provide in some cases an air inlet for the purpose of allowing the wash of the
water to create a current of air which materially adds to the ventilation. Immediately
the soil has passed the valve closes, preventing any noxious gases entering the portion
of the soil pipe before mentioned, from the upright or main soil pipe, and opening
the air outlet, and allowing all noxious gases remaining in that portion of the soil
pipe it is desired to ventilate to escape into the open air, they being replaced by fresh
air from the inlet before mentioned. In some cases one opening may be made to
serve the purpose of both outlet and inlet.
Referring to the Drawing accompanying this specification, in Fig. 1 is shown a
sectional view of one form of my apparatus. In this Fig. I employ the water valve a
usually termed a trap, and employ the opening b for the purposes of ventilation c
indicating the main soil pipe.
In Fig. 2 is shown my apparatus with a mechanical valve d which is actuated by
suitable chains or levers from the handle of the watercloset, the motion of which
is indicated by dotted lines d².
Attached to this and working with it is the smaller valve e which opens and closes
the ventilating inlet f, its motion being indicated by dotted lines e 2. The connecting
tube g. permits of the creation of a draught by the wash of the water as mentioned
herein before.
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 :-
1st. The combination of a watervalve_a_and air inlet with the soilpipe of a
watercloset substantially as described and shown hereinbefore, and in the accom-
nanging drawing for the nuns and forth

page_text: 2nd. The combination of a mechanical valve d, airinlet f closed by a valve e, and
air pipe g, with the soil pipe of a water closet, substantially as described and shown
hereinbefore and in the accompanying drawings for the purpose set forth.
3rd. The combination of a suitable valve and air inlet or inlets with the soil
pipe of a watercloset substantially as described hereinbefore for the purpose
set forth.
