PROVISIONAL SPECIFICATION.
Improvements in and connected with Pipe Joints, suitable for Use
with Water Closets, Slop Sinks, and the like.
I, CUMMING PATTON JAMIESON, of 23 Duke Street, Alnwick, in the County
of Northumberland, Architects Assistant, do hereby declare the nature of this
invention to be as follows:-
This invention relates to joints between water closets, slop sinks, and the like,
and the soil pipes used therewith. It consists in the application of a water seal
to the joint in question, and the maintenance of a supply of water in the said
seal.
The joint is made in the following manner :-The upper end of the soil pipe is
formed into an annular U shaped trough into which the end of the closet trap or
slop sink drops, the space between the two being filled with water, the same being
replaced from the flushing pipe, thus forming a perfect water sealed joint between
the two.
My invention is applied to a water closet as follows:-
;
The Ushaped trough as above described, is connected to the end of the trap
in the usual position, and the flushing pipe is continued downward a short distance
below the point at which it is connected to the closet. A short piece of pipe of
small diameter connects this downward extension of the flushing pipe with the
U shaped trough, thus keeping it constantly filled with water to form a scal and
also by reason of its small diameter ensuring that after the "flush out" of the closet
has taken place, sufficient water shall be left in the lower end extension of the
flushing pipe, to flow into the U shaped trough, aud replace the water already
there, which flows out through an opening left between the trap and the end of
the soil pipe. In some cases I cover the outer part of the U shaped trough with
an annular rubber or other suitable cover, for the purpose of excluding dust and
other foreign matter.
The interior diameters of the trap and the soil pipe are equal, thus securing a
clean run through without obstruction.
Dated this 1st day of July 1895.

COMPLETE SPECIFICATION.
Improvements in and connected with Pipe Joints, suitable for Use
with Water Closets, Slop Sinks, and the like.
I, CUMMING PATTON JAMIESON of 23 Duke Street, Alnwick, in the County
of Northumberland, Architects Assistant, 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 joints between water closets, slop sinks, and the like,
011...מ

page_text: and the soil pipes used therewith. It consists firstly in the application of a water
seal to the joint in question, and secondly the use in some cases of a device or
devices for replacing the water which forms the seal.
In its simplest form a joint according to my invention is applied to a water
closet as follows:-The upper end of the soil pipe is formed into an annular
U shaped trough into which the end of the closet trap or slop sink drops. The
annular trough being filled with water, it forms a perfect water sealed joint
between the closet trap and the soil pipe. The supply of water can be maintained
in any suitable manner, and from any convenient source.
In some cases I employ devices by means of which I am enabled to replace the
water forming the water seal either at will, or automatically at each flushing out
of the closet basin or slop sink.
In the accompanying drawings:-
:-
Fig. 1 is a vertical section of a water closet having a joint according to my
invention.
Fig. 2 is a vertical section of a similar water closet and joint having an
automatically operated replacement.
In Fig. 1 the basin of the closet may be of any suitable description but the co<
or nozzle a of the trap A must be so shaped and of such a diameter as to drop into
an annular trough which is formed by the upper end 6 and an outer wall 2 of
the soil pipe B. The end and outer wall 2 are so shaped and of such diameters
as to leave an annular water space both inside and outside the end or nozzle a of
the trap A; and when this nozzle is dropped into its place it is so arranged as to
leave an opening ³ under the end a of the trap and a second opening 64 between
the upper end of the soil pipe and the trap end. Thus any water supplied to
the annulus outside the nozzle a can pass downwards and through the space ³;
then upwards outside the nozzle a and as soon as it reaches the upper end b¹ flow
out through the opening into the soil pipe B.
The water in the joint may be maintained or replaced in any convenient manner,
such for instance as by screwing a pipe into the outer wall 63 and allowing a
continuous or intermittent flow of water to pass through the joint. I do not
restrict myself to any particular method of maintaining or replacing the water
forming the seal.
In Fig. 2 is shewn a water closet and joint similar to that illustrated in Fig. 1
but with the addition of an automatically operated replacement.
The flushing pipe C which opens into the basin at c in the usual manner, has
an extension c which is carried down to a lower point than c, and from this
extension c¹ a smaller pipe c³ is connected to the annular space b which contains
the water serving to form a sealed joiut. A rubber ring or other cover d serves
to prevent evaporation and to exclude dust and other foreign matter from the
annular water sealed space b.
The operation is as follows:-
Upon the contents of the flushing cistern being discharged the water descends
and fills the flushing pipe C, and flows out at the opening in the usual manner.
The opening c being a large one, and the pipe c' being much smaller, it follows
that when the flush out is completed and all the contents of the basin have passed
down the soil pipe a small portion of the flushing water remains in the extension c'
of the flushing pipe C. This continues to pass down through the pipe c² forcing
the water in the annular space b upwards and out of the opening into the
soil pipe B until the water has fallen to the level of the upper end 6' of the soil
pipe.
By this replacement of the water in the annular space 61 secure not only a
perfect sealed joint, but one in which the water is always pure. There is also no
chance of syphonage as the water seal is renewed after the basin is flushed out.
The manner in which my invention is applied to slop sinks, and the like, other
than water closets is so exactly similar to that herein before described that it is
unnecessary to make further reference to it.

page_text: Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In water closets, slop sinks, and the like, a water sealed joint between the trap
end or issuing nozzle, and the soil pipe, substantially as described and shewn.
2. In a joint for water closets, slop sinks, and the like, the combination of a
nozzle forming part of the basin, or sink, a trough which forms the upper end of
the soil pipe, and a body of water which fills such trough and forms a water sealed
joint between the basin or sink and the soil pipe.
3. In water closets, slop sinks, and the like, a water sealed joint between the
trap end, or issuing nozzle, and the soil pipe, the water forming such joint being
replaced either at intervals or continuously.
4. In joints for water closets, slop sinks, and the like, the combination of a
nozzle forming part of the basin, or sink, a trough which forms the upper end of
the soil pipe, a body of water which fills such trough and forms a water sealed
joint between the basin or sink and the soil pipe, a supply pipe having an extension
below the level of the opening of the same, and a smaller pipe or opening
connecting the extension to the trough, in such manner as to secure a replacement
of the water forming the seal after each flush out of the contents of the basin,
substantially as described and shewn.
5. In joints for water closets, slop sinks, and the like, the combination of the
nozzle a, the trough b, the extension c¹ of the supply pipe C, and the smaller pipe
or opening c³, substantially as described and shewn.
Datel this 7th day of January 1896.
