PROVISIONAL SPECIFICATION.
Improvements in Automatically Flushed Water Closets.
I ALFRED MOUNTAIN FOWLER the Younger of 3 Warren Street Stockport
in the County of Chester Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the construction and arrangement of water closets such
as are automatically flushed by waste water from the slopstone, or lavatory or the
roof or surface drainage from the yard or passage or any combination of such waste
waters or drainage, such for example as those wherein a tipping tank is placed
immediately below the pan and the waste water from the slopstone or sink and the
excreta both fall direct into such tipping tank.
According to the first part of my invention, a short sloping pipe leads from
the bottom of the chamber in which the tank is situated and immediately outside
the wall of the closet it dips down and forms a sealed joint or trap before procceding
onwards to the main drain.
Immediately above this trap I place a vertical pipe leading upwards to the grid
or gulley in the yard over which the down spout from the roof bathroom or other
source of waste water may be placed. The level of the water in the seal or trap is
below the opening of the short sloping pipe above named, so that there is a clear
way for ventilation through the yard grid or gulley at the same time that it is
thoroughly trapped from the main sewer.
A second part of my invention consists in reducing the lower part of the pan
and fitting it into the upper part of a short socket pipe resting on the top of
the tank chamber the diameter of the said short pipe being larger than the throat
of the pan so that the excreta will fall clear of the inside of this pipe, and I
support the seat by means of a hollow pedestal of a curved or U-shape in hori-
zontal section the foot of which rests upon and is supported by the floor of the
closet.
According to a third part of my invention when it is desired to apply the same
to two, three, or more closets in juxtaposition, the waste water supply and tipping
tank is connected to the first of the closets only. The sloping pipe from the tank
chamber is carried on beneath the other closet or closets to the outside yard or
passage, where it is connected with the upright ventilating shaft or pipe to the yard
grid or gulley and dips down so as to form a sealed joint or trap before proceeding
to the main drain.
Beneath the second closet (and succeeding closets if more than two) a dip or
basin is made in the lower side of the sloping pipe to contain water and to receive
the excreta, and when the tipping tank is overbalanced the water flushes out these
dips or basins as it flows along the sloping pipe on its way to the sealed joint or trap
leading to the main drain.

COMPLETE SPECIFICATION.
Improvements in Automatically Flushed Water Closets.
I ALFRED MOUNTAIN FOWLER the Younger of 3 Warren Street Stockport
in the County of Chester Engineer, 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 the construction and arrangement of water-closets such
as are automatically flushed by waste water from the slop-stone, or lavatory or the
roof or surface drainage from the yard, or any combination of such waste waters or
drainage, such for example as those for which Letters Patent No. 15528 dated.
September 14th 1891 were granted to me, wherein a tipping tank is placed imme-
diately below the pan and the waste water from the slop-stone or sink and the
excreta both fall into such tipping tank.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
According to the first part of my invention which is illustrated by the sectional
view Fig. 1 on the drawings it relates to the construction of an intercepting trap or
chamber a (in connection with slop or waste water closets shown in dotted lines)
having a vertical ventilating shaft on the inlet side of the trap, which trap is
preferably placed immediately adjoining the outside wall of the closet and may be
either surmounted at the ground level with a grid or gulley as shown at cor:
the vertical pipe b may be fitted with a stopper and have a side junction connected
with an extended vertical pipe d carried to the eaves of the adjoining roof.
The level of the water in the seal of the trap being a few inches below the inlet
pipe e from the closet so that there is a clear way for ventilation through the above
named grid or gulley e and the closet pan or pans, and by this means any sewer
gases escaping beyond the seal of the trap a ascend and escape through the yard
grid c and are so prevented from ascending the closet pan. This grid or gulley c
offers a ready access to the trap in case of stoppage and such access can be obtained
from the outside of the closet without interfering with, or necessitating any
displacement of, the closet pan or floor.
A second part of my invention which is illustrated by the section Fig. 2 consists
in reducing the lower part of the closet pan (shown dotted) and fitting it into the
socket of a vertical lengthening pipe by means of a diminishing piece formed in
the manner as shown at h on Fig. 2 of the accompanying drawings, the diameter of
the said lengthening pipe g being larger than the throat of the pan f so that the
excreta or urine will fall clear of the inside of the pan below; or instead of
contracting the lower part of the closet pan, the same effect may be obtained
with a parallel sided pan by simply using a lengthening pipe of larger. diameter.
The next portion of my invention, illustrated by Fig. 3 horizontal section,. Fig. 4
vertical section and Fig. 5 front elevation, relates to the construction of a support 4
to the closet seat by means of a hollow pedestal i of a curved or U-shape in
horizontal section, the foot of which rests upon and is supported by the floor k of
the closet and is designed to enclose the pan of the closet..
I would here remark that in the Provisional Specification filed with my
application for Letters Patent I described a third part of my invention as 4
applicable to two; three or more closets in juxtaposition, but since filing such
Specification I have found that this portion of my invention is not so new or useful as
I then believed it to be, and I therefore do not propose to make any claim to such
arrangement as forming any part of my present invention.

page_text: 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 slop or waste water closets, the employment of a trap or chamber between
the closet pan and the main drain having a vertical ventilating shaft on the inlet
side of the trap as described and illustrated.
2. Fitting the lower part of the pan into a lengthening pipe of larger size so that
the excreta or urine will fall clear of the inside of the pipe below, substantially as
hereinbefore described.
3. In closets the arrangement of a pedestal which rests upon and is supported
by the floor of the closet, and designed to enclose the closet pan, and support
the seat.
4. The general arrangement and combination of the several parts in waste
water closets substantially as before described, and illustrated, by the drawings
annexed.
