PROVISIONAL SPECIFICATION.
Improvements in Water Closets, or Water Closet Basins and Traps.
I, EDWARD TRAIES, trading as Traies and Son, of 6 Elgin Crescent, Notting
Hill, in the County of London, Sanitary Engineers and Universal Contractors, do
hereby declare the nature of this invention to be as follows:-
My invention has relation to pans, basins, or receivers of water closets, and the
traps in connection therewith, and is designed, (a) to prevent the sides or walls, or
the bottom of the basin, being fouled by soil or urine, firstly, by protecting the
walls or sides by their shape or position; and secondly, by maintaining a high
water level in the basin; (b) that the outgo is so constructed, that the only non-
metallic joint necessary, is always protected from the escape of sewer gas, by the
water seal of the trap; also that the metallic thimble forms the trap; and all
joints therefrom to the drains may be metallic; the metallic thimble is so placed
that the trapping of the closet does not interfere with the flushing pipe; the outgo
is placed at the back of the closet, and the bottom of the basin from the water
line to the outgo, is continuously sloped to the same, the outgo being the lowest
point.
In carrying out my invention therefore, I provide a form of water closet, that,
although practically of the wash down type, maintains a water level equal in
height, and protection to the walls or sides of the basin or receiver, equal to the
best forms of "valve closet"; essentially differing from all kinds of "wash down."
closets in its form, and by its relationship to the thimble which forms the trap, and
the height of the water level made possible thereby; and differing from any form
of "wash out" closet, by permitting the flush of water a direct action in clearing
the contents of the basin out of the trap, without having to first carry it over a
"weir," and no "weir" is formed to maintain the water level, except by the trap
itself.
The connection or joint between the outgo of the basin and the metallic thimble,
I propose to seal with Portland cement or other suitable material, or, if I may so
elect, I may make the basin and trap in one piece of earthenware, of identical
shape or principle, or a variation in shape of the same principle.
I propose that the area of the surface of the water maintained in the basin, shall
be equal to the greatest horizontal area of the basin, and the bottom slope of the
basin shall be in a concave form, from the walls or sides of the basin at the water
line, in all directions to the outgo, and that the outgo shall project horizontally, a
sufficient distance to allow a proper socketted connection being made.

closet and trap, showing the soldered connection to the soil pipe, and the non-
metallic joint to the outgo.

Improvements in Water Closets, or Water Closet Basins and Traps.
I, EDWARD TRAIES, trading as Traies & Son, of 6 Elgin Crescent, Notting
Hill, in the County of London, Sanitary Engineer and Universal Contractor, 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 the pans, basins or receivers of water closets and the
traps in connection therewith, and has the following characteristics, viz. :-The
sides or walls or the bottom of the basin are prevented from being fouled by soil
or urine, firstly by protecting the walls or sides by their shape or position, and
secondly by maintaining a high water level in the basin. The out-go is so
constructed that the only non-metallic joint necessary is always protected from the
escape of sewer gas by the water seal of the trap; the metallic thimble forms the
trap so that all joints therefrom to the drains may be metallic; the metallic thimble
is so placed that the trapping of the closet does not interfere with the flushing
pipe the out-go is placed at the back of the closet and the bottom of the basin,
from the water line to the out-go, is continuously sloped downwards to the same,
the out-go being the lowest point.

In carrying my invention into effect, I provide a form of water closet that,
although practically of the "wash-down" type, maintains a water level which, in
height and protection to the walls or sides of the basin or receiver, is equal to the
best forms of "valve closet," essentially differing from all kinds of "wash-down
closets in its form, and by its relationship to the thimble which forms the trap, and
the height of the water level made possible thereby; it also differs from any form
of wash out closet by permitting the flush of water a direct action in clearing
the contents of the basin out of the trap without having to first carry it over a
"wier," and no * wier
is formed to maintain the water level, except by the trap
itself. The connection or joint between the out-go of the basin and the metallic
thimble, I propose to seal with Portland cement or other suitable material, or I
may make the basin and trap in one piece of earthenware of identical shape or
arrangement, or the form may be somewhat varied without departing from the
peculiar character of my invention. 1 propose that the area of the surface of the
water maintained in the basin shall be equal to the greatest horizontal area of
the basin, and the bottom slope of the basin shall be in a concave form from the
walls or sides of the basin at the water-line in all directions to the out-go, and that
the out-go shall project horizontally a sufficient distance to allow a proper
socketted connection being made.
Fig. 1 of the drawings accompanying my Provisional Specification represents a
vertical section through the closet and trap, showing the soldered connection to the
soil pipe and the non-metallic joint to the out-go. a a are the sides or walls of the
closet, b is an inlet arm for the flushing pipe, c is a flushing rim, d is the out-go,
e is the bent metallic thimble forming the trap, f is the cement on non-metallic
joint, g is the soil pipe connected to the metallic thimble by a soldered joint.

showing the direction of the metallic thimble e on leaving the out-go, which may
be varied in shape or direction.

bent thimble in two of its forms, one being in full lines, the other in dotted lines.

showing the position of the out-go.
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. The improved construction of water closets or water closet basins and traps
substantially as herein set forth.
2. In water closets or water closet basins and traps, the peculiar construction
of parts whereby the water surface and level are maintained as shown in the
drawings, and the non-metallic joint between the out-go and trap is always under
water seal, substantially as herein set forth.
3. In water closets or water closet basins and traps, the peculiar construction
of parts whereby the water surface and level are maintained as shown in the
drawings, the non-metallic joint between the out-go and trap is always under
water seal and the flushing pipe is retained at the centre of the basin at the back,
substantially as herein set forth.
4. In water closets or water closet basins, the peculiar construction of trap
formed partly by the out-go and closet basin and partly by a rising metallic
thimble or bent tube connected with the out-go by a joint which is always under-
water seal, substantially as herein set forth.
