We ROBERT GEORGE LAING BURN of 23 Charlwood Street, Pimlico, in the County
of Middlesex, and JOHN MACDONALD of 63 and 65 Hanover Street, Edinburgh in
the County of Midlothian, North Britain, Sanitary Engineers do hereby declare the
nature of this invention to be as follows:-
The chief object of our Invention is to combine the advantages of the so called
combination and pedestal closets with valve closets whereby we obviate the objection
heretofore found of having the connection to the soil pipe on the drain side of the
trap, whereas by our invention we are able to provide a combination or pedestal closet
with the connection to the soil pipe on the house side of the trap.
Our invention is also applicable to valve closets enclosed within seat in the usual
way.
According to our invention we make the pan or basin, valve box, and enclosure,
preferably in one piece, and of earthenware stoneware or metal, enamelled or other-
wise by which means we avoid making any joint between the pan or basin and valve
box and encolsure, and thus prevent the lodging of any slops or urine or from their
getting between the basin and enclosure to the interior or to the working parts. The
enclosure also forms or acts as a support or strengthening piece for the basin;
although the basin and valve box may be made without the enclosure and fitted with
seat and pull in the ordinary way.
In the enclosure we provide panels at the side, and also, if required, at the front
in order to be able to communicate when necessary with the interior or working parts.
The soil pipe may be trapped in the ordinary way.
In the back of the valve box
there is an aperture to receive the pan or basin valve, and below same there is an
aperture for the double purpose of ventilation and overflow, as more particularly
hereafter described.
To the back of the pan or basin and preferably in a piece therewith we
or two service boxes communicating with the overflow below same whereby a supply
provide one
of water is maintained after the basin flush has closed or stopped, and these boxes
also serve as a means for supporting or strengthening the enclosure before referred to,

page_text: at the upper part thereof; one only of such boxes may be used as a service box the
other then acting merely as a support; the water inlet is between these two service
boxes. The bed plate or frame is made with a jacket to enclose the valve box, and to
this jacket we connect the spindle that carries the lever and the other working parts
in connection with the valve by this means we provide a firm support or bearings for
all the working parts without interfering with the earthenware box or pan, and con-
sequently there is no strain on the latter. The pan or basin valve before referred to,
which is inserted in the aperture at the back of the valve box, is made with the valve
proper and seating and trap from overflow pipe; this trap is made with a double
partition so that the water must go down below one partition and over the other
partition before escaping to the waste. The trap is made in two parts the connection
being on the line of the first partition, and secured by screws, the joint should of
course be secured with cement. By this means we are able to examine the partitions
with facility, to ascertain whether or not the metal is sound.
The waste pipe is primarily a ventilating pipe from the valve chamber or box
because when water is discharged from the basin any suction that may be created by
the down flow in the soil pipe will not affect the water in the overflow trap, the venti-
lating pipe aforesaid being in direct communication with the chamber and not with
the overflow trap, which latter is a branch into the ventilating pipe, or in other words
the suction will be more liable to draw from the ventilating pipe than from the over-
flow, the latter being branched into the former. or ventilating pipe; we thus provide
means whereby the trap cannot be sucked or syphoned: A ventilating pipe from the
chamber is not new,
but it is new to branch the overflow into the ventilating pipe.
These closets may be flushed from a water waste preventer and by a pull in the
ordinary way and when applied as a pedestal closet there must be a connection with
the valve lever of the closet and the pull of the water waste preventer.

Improvements in Pedestal, Combination, and Valve Closets.
We, ROBERT GEORGE LAING BURN of 23 Charlwood Street, Pimlico in the County
of Middlesex and JOHN MACDONALD of 63 and 65 Hanover Street Edinburgh in
the County of Midlothian. North Britain, Sanitary Engineers do nereby 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 :—
The chief object of our invention is to combine the advantages of the so-called
combination and pedestal closets with valve closets whereby we obviate the objection
heretofore found of having the joint or connection of the apparatus to the soil pipe on
the drain side of the trap.
This construction of basin and valve box is also applicable to valve closets enclosed
within seat in the usual way.
According to our invention, and with reference to the accompanying sectional
drawing, we make the pan or basin A, valve box A¹, and enclosure A² preferably in
one piece, and of earthenware, stoneware, or metal, enamelled or otherwise, by which
means we avoid making any joint between the pan or basin A and valve box A¹ and
enclosure A2, and thus prevent the lodging of any slops or urine, or from their getting
between the basin A and enclosure A² to the interior or to the working parts. The
enclosure A' also forms or acts as a support or strengthening piece for the basin A,
although the basin A and valve box A may be made without the enclosure A², and
fitted with seat and pull in the ordinary way.
In the enclosure A² we provide panels or openings at the side and also if required
at the front in order to be able to communicate when necessary with the interior or
working parts. The soil pipe may be trapped in the ordinary way.
In the back of the valve box A' there is an aperture F to receive the pan or basin
valve F and below same there is an aperture B for the double purpose of ventilation
and overflow, as more particularly hereafter described.
To the back of the pan or basin and preferably in a piece therewith we provide
one or two service boxes communicating with the overflow below same, whereby a
supply of water is maintained after the basin flush has closed or stopped and these
boxes also serve as a means for supporting or strengthening the enclosure before
referred to, at the upper part thereof; one only of such boxes may be used as a service
box, the other then acting merely as a support; the water inlet is between these two
service boxes.
The bed plate or frame is made with a jacket D to enclose the valve box A', and
to this jacket D we connect the spindle that carries the lever and the other, working
parts in connection with the valve. By this means we provide a firm support or
bearings for all the working parts without interfering with the earthenware box or
pan and consequently there is no strain on the latter. The pan or basin valve F
before referred to which is inserted in the aperture F at the back of the valve box, is
made with the valve proper and seating and trap from overflow pipe; this trap is

page_text: made with a double partition so that the water must go down below one partition H
and over the other partition E before escaping to the waste. The trap is made in
two parts the connection being on the line of the first partition E and securel by
screws, the joint should of course be secured with cement."
By this means we are able to examine the partitions with facility to ascertain whether
or not the metal is sound.
The basin or pan valve F¹ may be constructed having a metal seating and india
rubber face, or the seating may be formed in the earthenware and faced with rubber
as before in this latter case considerable stress or strain would be applied to the
earthenware which must be strengthened and fixed accordingly.
?
The waste pipe B₁ is primarily a ventilating pipe from the valve chamber or box A¹
because when water is discharged from the basin, any suction that may be created by
the down flow in the soil pipe will not affect the water in the overflow trap, the venti-
lating pipe B aforesaid being in direct communication with the chamber A¹ and not
with the overflow trap E E¹ which latter is a branch into the ventilating pipe B', or in
other words the suction will be more liable to draw from the ventilating pipe B
than from the overflow viz. the overflow E E¹ being branched into the former or
ventilating pipe B₁, we thus provide means whereby the trap cannot be sucked or
syphoned. A ventilating pipe from the chamber is not new, but it is new to branch
the overflow into the ventilating pipe in the manner described.
These closets may be flushed from a water waste preventer and by a pull in the
ordinary way, and when applied as a pedestal closet there must be a connection with
a valve lever of the closet and the pull of the water waste preventer; or the said
closets may be flushed by means of a valve under the apparatus.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First :—The construction of the pans or basins of combination, pedestal valve or
other valve water closets, in one piece with valve box and with or without enclosure
avoiding the necessity of forming a joint at the junction of the pan and valve box
substantially in the manner and for the purposes herein set forth.
Second-The particular construction and arrangement of overflow and ventilating
pipe as herein described.
Third-In pedestal, combination, and valve closets, the construction of the pans
or basins A formed in one piece with their valve boxes A¹, and enclosures A2, in com-
bination with the overflow and ventilating pipes and parts in connection therewith
substantially as and for the purposes herein set forth.
