I, WILLIAM ROSS Junr. Builder Clarmont Road Sparkbrook in the County of
Warwick do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of drain pipes formed of an arched curvilineal
configuration for the purpose of providing at the apex of the arch a sufficient fall for
the flowing liquid to act as a seal, and prevent the backward egress of noxious gases,
the drain pipe is technically known as a siphon pipe. The object of my invention
is to so improve the configuration and construction of the pipe as to allow facilities
for removing sediment that accumulates in the lower part of the inverted arch,
this lower part is liable to be stopped or blocked with the sediment and refuse
carried along the pipe with the flowing liquid. Some alkalies and other
substances passing through the flowing liquid will when deposited in the bend of
the pipe set up a chemical action and thereby amalgamate with the material con-
stituting the barrel of the siphon pipe, the continual collection of deposit
ultimately becomes so incorporated with the material constituting the shell of the
barrell that the passage -becomes--permanently blocked and the pipes previously
forming a drain would be no longer a drain but merely a continuous length of
empty piping extending beyond the blocked passage, the liquid and refuse above
the blocked passage accumulates and becomes a serious nuisance. Hitherto it has
been necessary to remove the blocked siphon pipe such a method of procedure entails
great loss of time and expense. To remedy the defects in the manufacture and.
configuration of the siphon pipe I proceed to carry out my invention in the following
manner :-
I provide a siphon-pipe with the necessary dip to enable the flowing liquid to form
a seal excluding the passage of noxious gases.
The connecting ends of the syphon pipe would be of a suitable transverse section
to correspond with drain pipes to which it would be connected.
The transverse section of the siphon pipe would increase gradually from each end
to any desired size in or at the centre. The crown of the siphon pipe is next extended
upwards and formed into a tapered outlet branch.

page_text: The transverse configuration of the end of the outlet branch may be circular or
of any other shape suitable to connect to the uptake pipe.
1 next provide convenient lengths of uptake piping formed with suitable flanges
such lengths of piping would be connected together and also connected to the
cleaning branch of the siphon.
The outlet pipes would extend upwards to the ground line and would terminate
with a suitable cap or other covering.
The construction of the siphon pipe with the outlet branch of the configuration herein-
before set forth constitutes the first modification of my invention, the construction of
the uptake pipe in the manner hereinbefore set forth and the combination and
connected of it with the outlet branch of the siphon pipe constitutes the second
modification of my invention. I am aware that siphon pipes have been made with
a short uptake branch, such a branch being formed vertically with the axis of the
pipe and such branch being of a circular transverse section, but pipes so made have
proved to be ineffectual when placed at any considerable depth below the ground,
because the vertical walls of the short uptake branch have prevented the use of a
suitable scraper or ladle to remove the sediment.
By constructing my uptake branch to rise from the crown of the siphon and then
taper upwards to the ontlet end of the said branch, 1 thereby form a longitudinal
passage and thus provide for the radiation and use of a suitable tool to remove the
sediment, such tool may form a subject for a separate and independent patent.

Improvements in Siphon Drain Pipes and their Connections.
I WILLIAM Ross Junr. Builder, Clarmount Road Sparkbrook in the County of
Warwick 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 that class of drain pipe formed of an arched curvilinical
configuration, for the purpose of providing at the apex of the arch a sufficient fall for
the flowing liquid to act as a seal, and prevent the backward egress of noxious gases,
the drain pipe is technically known as a siphon pipe.
The object of my invention is to so improve the configuration and construction of
the pipe as to allow facilities for removing sediment that accumulates in the lower
part of the inverted arch, this lower part is liable to be stopped or blocked with
sediment or refuse, carried plong the pipe with the flowing water, some alkalies and
other substances passing through the flowing liquid, will when deposited in the bend
of the pipe, set up a chemical action and thereby amalgamate with the material con-
stituting the shell or barrel of the siphon pipe, the continual collection of deposit will
ultimately become so incorporated with the material constituting the shell or barrel
that the passage becomes permanently blocked and the pipes previously forming a
drain would be no longer a drain but merely a continuous length of empty piping
extending beyond the blocked passage, the liquid and refuse above the blocked passage
accumulates and becomes a serious nuisance.
Hitherto it has been necessary to remove the blocked siphon pipe; such a method
of procedure entails great loss of time and also great expense; to remedy the defects
in the manufacture and configuration of the siphon pipe I proceed to carry out iny.
invention in the following manner.
I provide a siphon pipe with the necessary dip, to enable the flowing liquid to form
a seal excluding the passage of noxious gasses.
The connecting ends of the siphon-pipe would be of a suitable transverse section to.
correspond with drain pipes to which it would be connected.
The transverse section of the siphon-pipe would increase gradually from each end,
to any desired size in, or at the centre.
The crown of the siphon-pipe is next extended upwards and formed into a tapered
outlet branch.
The transverse configuration of the end of the outlet branch may be circular, or of
any other shape suitable to connect to the uptake-pipe.
1-next-provide convenient lengths of uptake piping formed with suitable flanges,
such lengths of piping would be connected together and also connected to the cleaning
branch of the siphon.
The outer pipes extend upwards to the ground line and would terminate with a
suitable cap or other covering.
The construction of the siphon pipe with outlet branches of the configuration

page_text: herein before set forth constitutes the first modification of my invention, the con-
struction of the uptake-pipe in the manner hereinbefore set forth and the combination
and connection of it with the outlet branch of the siphon pipe constitutes the second
modification of my invention.
I am aware that siphon pipes have been made with a short central uptake pipe or
branch, such branch being formed of a transverse sectional aria equal to and corre
sponding with the area of the inlet ends of the siphon-pipe such siphon pipes being
made of a similar transverse section throughout. Siphon pipes so made or constructed
I do not claim as my invention.
By constructing my improved siphon-pipe with an uptake branch rising from the
crown of the said siphon pipe, such uptake branch being of sufficient dimensions to
extend over the well or bulged ont part, I thereby form a passage large enough to
use as a man-hole or to permit the radiation and use of a scraper, ladle, scoop, or
other suitable tool or tools by means of which the sediment can be loosened and
removed from the well of the siphon-pipe.
I will now proceed to describe with reference to the accompanying drawings the
various shapes and modifications forming my improved siphon-pipe.
Figure 1 is a section of figure 3 on the line A B.
Figure 2 is an end view of figure 3.
Figure 3 is a plan of figure 4.
Figure 4 is a longitudinal section of figures 3 and 5.
Figure 5 is a plan of siphon pipe with oval outlet.
Figure 6 is a section of figure 5 on the line E. F.
Figure 7 is a broken section of part of figure 4 shewing a small outlet for
ventilating pipe.
In carrying out my invention I in some cases form my siphon-pipe of the con-
figuration shewn in longitudinal section at figure 4 and in transverse section at
figure 6 and in plan at figure 5.
a figure represents the internal end of dip or main uptake pipe: it will be readily
seen that the said end a of dip is at a great depth below the bottom surface of
outlend ends c and d thus forming a safe seal excluding the passage of noxious gases
from the length of piping connected to the end c or to the end c'.
The siphon pipe would usually he formed with a socket at one end as shewn at a
figures 4 and 5, the other end of the said siphon pipe being formed of similar con-
figuration to that of the pipe body which in the case of the pipe illustrated at figures 1,
2, 3, 4 and 5 would be of a circular transverse section suitable to fit into the socket of
any ordinary drain-pipe.
In some special cases I prefer to form a socket at both ends in the manner
represented at c and c¹ figure 4.
The branch sockets d, d' are provided for use in clearing out the well e of the
siphon-pipe.
It will be observed that the internal diameter of the branch sockets d d' correspond
with the internal diameter of the siphon-pipe at ff. by this correspondence. of
dimensional arias I can utilize the uptake pipes connected to the branches d d in the
following manner.
I can provide a plate of sheet iron or other suitable material cut to fit the internal
transverse section of the siphon pipe on the line G. H; this plate can be fixed to a
pole, tube, or rod of any desired length and lowered untill it fits into and effectually
blocks up the passage from the inlet end c, thus preventing liquid from flowing into
the well e; a precisely similar plate can be also lowered through the branch d¹ and
thus prevent liquid from flowing into the well from the end c¹.
The connection of two branches similar to d and d to a siphon pipe is a new
arrangement and adaptation.
On reference to figure 5 it will be observed that the central part and uptake socket
are of an oval configuration, the transverse dimensions on the line E. F. gradually
diminishing towards each end h of the pipe.
In some cases 1 prefer to make the transverse dimensions from E to F figure 5 and

page_text: from J to K figure 6 correspond with the transverse dimensions from A to B figure 3,
gradually diminishing towards och end in the manner illustrated at figure 3, that
is to say the plan would correspond with figure 3 excepting that the central uptake
would be formed with an oval mouth similar to g figure 5.
The siphon pipe made in the manner hereinbefore set forth would be fixed at
any desired depth connected to any ordinary series of drain pipes.
A central oval uptake pipe, K would next be provided, either in one continuous
piece or in short lengths joined together by sockets or other suitable connections:
the top end of the uptake pipe may be level with the ground line or it may project
any suitable distance above the ground line; a suitable cap or cover is provided
and connected over in on or to the top end of the said uptake pipe.
My improved siphon so connected would answer every purpose of any ordinary
siphon pipe and in addition offer practical facilities for clearing out the well part e.
The exceptionally large dimensions of the well part e (in proportion to the
inlets ff) would enable the siphon pipe to act continuously for a considerable length
of time but when the collection of sediment eventually filled the well part e rising and
choking the circular passages beyond the sealing face d the well part e could then
be thoroughly cleaned out by means of a man, entering at the well e or by means of a
ladle, a scoop, a scraper, or other suitable tool or tools lowered down the uptake pipe
into the well part e.
Instead of forming the central uptake socket of an oval configuration as represented
at figures 5 and. 6 I can form it of a circular configuration as represented at m
figures 1, 2, and 3, the length of uptake pipe would also be of a circular transverse
section as clearly illustrated at n figure 3.
The longitudinal section figure 4 is a perfect section of the circular uptake
arrangement shewn at figure 3, it is also a perfect section of the oval arrangement
shewn at figure 5 excepting the additional socket c'.
In some cases instead of providing uptake branches d d of equal transverse area to
the outlet end ff I may provide branches with diminished areas as shown at p
figure 7.
In other cases I can dispense with the uptake branches d and d' and continue the
curve in the manner dotted in at q q' figure 4, in such cases the sewer gases would
rise through the large central uptake.
In some cases I provide a strengthening rib or web as shown at
and 5, the rib would be provided on both sides of the central uptake.
figures 3, 4
What constitutes my invention is the formation of a syphon pipe in the manner
herein before described in contradistinction "to an ordinary siphon pipe which
consists of a pipe the internal diameter or bore of which is of the same transverse
dimensions throughout altho bent or dipped to form a water seal for the purpose
of excluding the passage of sewer gases"; whereas the internal and external areas
of my pipe increase gradually from each end bulging out at the centre to an area
many times greater than that of the inlet ends.
The inlet ends c and c³ are represented of the circular form most suitable to connect
to straight drain pipes of ordinary commerce the end view shewn at figure 2 illustrates
the manner in which the small round part c is gradually expanded and increased
to the largest dimension, the rounded contour following the increasing dimensions ;
altho I consider the rounded contour to be the most practical method of forming
the bulged or expanded portion of iny improved siphon-pipe; nevertheless I can
where desired form the transverse section of the ends and of an oval or polygonal
section and extend or increase the dimensions of the oval or poligon over the
expanded or bulged out surface.
I can form round (or curved) corners at the outlets of the uptake pipes d and d¹ in
the manner represented at s¹² or I can form acute angles as shewn at tttt.
The sides of the main uptake instead of being tapered in the manner represented
can be tapered the reverse way or made parallel; in such cases the points a a¹
could remain as illustrated and the points extended thus increasing the relative
dimensions of the pipe K.

invention and in what manner the same is to be performed 1. declare that what I
claim is
1st. The invention as illustrated and described for the purpose described.
2nd. The making of a siphon pipe with an enlarged or bulged central part, of the
relative proportions as illustrated in accordance with scale.

combination with a central uptake pipe as illustrated and described for the purpose
described.
4th. The making of a siphon pipe with an enlarged or bulbous central part in
combination with a central uptake pipe or socket and two vertical (end) uptake
sockets for the purpose of connecting to any system of ordinary drain pipes and
