1 ARTHUR CHARLES HENDERSON of 46 Southampton Buildings, Holborn in the
county of Middlesex, and of 31 Lincoln Place, Leinster Street, Dublin Patent Agent
do hereby declare the nature of the said invention for IMPROVEMENTS IN SYPHON TRAP
CLOSET PANS a
communication to me from abroad by Alfred de la Escalera,
Architect of Santander in the Kingdom of Spain, to be as follows:-
Fig. 1 of the accompanying drawings represents a syphon trap closet pan, of the
description embodying my invention, its object being to prevent sewer gases from
entering the house by way of the closet.
The pan and its accessories in this Figure are shown in section. The apparatus is
inodorous, the pan a, is united with the syphon.
At the upper part of the pan a, a large ring a', is made, which is open at its under
part, the object being to spread the flushing water all round the pan, in one con-
tinuous sheet for cleansing it on all sides. Connected with, and forming part of this
pan is the syphon in form of an S, provided with a large register b, near the discharge,
which is usually closed by a lid c, and some such matter as mortar, cement or plaster,
for preventing the escape of the sewer gases, and also admitting of removal for clearing
the syphon of any obstructions, without the necessity of taking the closet to pieces.
At the rear of the syphon is another register d, also intended either for facilitating
cleansing, for ventilating purposes, or for allowing of the passage of the slops and so
forth from the Bath rooms, lavatories etcetra, where the construction of the house will
admit of so doing at the side of this register a current of water is admitted which
completely cleanses the bottom of the syphon, and which acts at the same time with
the flushing water, which with it, is admitted through two leaden pipes having a
simple tap in front of the junction of the two pipes shown by the dotted lines.

page_text: I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings, Holborn in the
county of Middlesex and of 31 Lincoln Place, Leinster Street Dublin, Patent Agent
do hereby declare the nature of the said invention for "IMPROVEMENTS IN SYPHON TRAP
CLOSET PANS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement, a communication to me
from abroad by Alfred de la Escalera, Architect of Santander in the Kingdom of
Spain
The object of this invention is to prevent sewer gas entering houses by way of the
closet, and at the same time to render the latter perfectly inodorous by keeping the
pan clean and clear of any obstructions or deposits (which are hidden from view by
the formation of the pan) by thoroughly flushing it, by a simple ready and expeditious
method.
Fig. 1 of the accompanying drawings represents a closet pan of the description
embodying my invention seen in vertical elevation. Fig. 2 is a similar view thereof
in section. It may be constructed of glazed earthenware, porcelain, glass, iron, or
other suitable substance.
The pan and its accessories in these Figures are lettered with like letters of
reference.
a
The apparatus is inodorous, the pan a, is united with the syphon, at the upper part
large ring a' is made, which is open at its under part, the object being to spread the
flushing water all round the pan in one continuous sheet for effectually cleansing it on
all sides.
Connected with, and forming part of this pan is the syphon of S form, provided
with a large register b, (near the discharge) which is usually closed by a lid c, and
some such matter as mortar, cement, or plaster, for preventing the escape of the sewer
gas, and also admitting of removal for clearing the syphon of any obstructions, without
the necessity of taking the closet to pieces.
At the rear of the syphon is another register d, also intended either for facilitating
cleansing, for ventilating purposes, or for allowing of the passage of the slops and so
forth froin the bath rooms or lavatories, where the construction of the house will
admit of so doing.
At the side of this register a current of water is admitted at b', which completely
cleanses the bottom of the syphon, and which acts at the same time as the flushing
takes place, the water of which with the current alluded to is admitted through two
leaden pipes having a simple tap in front of the junction of these two pipes, shown by
the dotted lines.

page_text: Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1st. The inodorous sanitary closet pan a, provided at its upper part with a large
ring a', open underneath for producing an annular sheet of water for cleansing the
sides of the pan all round, the said pan being connected to the S shaped syphon for
concealing the focal matter which may be deposited at the bottom.
2nd. An inodorous syphon of S form, one of whose ends bserves as discharge outlet,
and the other 6' for the passage of a current of water for cleansing the bottom of the
syphon.
3rd. An inodorous syphon having two registers c. d. for inspecting and cleansing
the syphon, the register d, being also used for ventilation, or for receiving the water
from bath rooms and so forth.
