PROVISIONAL SPECIFICATION.
Improvements in and connected with Soil Pipes, and Ventilating
Shafts therefor.
We, WILLIAM JAMES FREEMAN, and EDWIN FREEMAN, both of 99 York
Road, Battersea, in the County of Surrey, Sanitary Engineers, do hereby declare
the nature of this invention to be as follows:-
:-
The object of this invention is to simplify the connection of the outgo pipes from
water closets and the like to the vertical soil pipe and to facilitate the connection of
the ventilating shaft thereto and to the building.
Now according to one method of carrying out the first part of our invention we
do away with the ordinary lead tee piece to which the outgo pipe is usually
attached and use instead thereof a pipe constructed of tinned iron or copper the
said pipe having an orifice at one side thereof to admit of the insertion of the outgo
pipe froin the trap the edges of which orifice may be beaded or slightly flanged the
ends of the pipe being made with a socket at the top and a spigot at the bottom or
we may provide the same with flanges if desired. We may also form lugs on the
pipe to enable the same to be secured to a wall or other structure.
Instead of the iron pipe hereinbefore mentioned we may form the same of brass
copper or gun metal lined with lead in which case the brass or other tube is slightly
flanged at the bottom and the lead lining turned over it and also over the bottom of
the socket end the brass copper or gun metal tube being tinned round the orifice at
the side to enable the joint to be securely wiped.
According to a modification of our invention we provide brass or gun-metal
thimbles or casings one being made with a socket and the other with a flange.
These thimbles or casings are thoroughly tinned inside and placed in the mould and
the ordinary lead tee piece cast inside them when cool the casings will be securely
attached to the lead.
By these improved connections we are enabled to caulk all soil pipe joints with
lead if required.
The other part of our invention relates to a new terminal pipe for the ventilating
shaft which consists of a pipe of cast iron or other suitable material of sufficient
length to reach to the minimum regulation height above the caves and having a
double curve of large radius therein to enable the upper end of the said pipe to
stand clear of the eaves lugs are formed on or attached to the portion of the pipe
below the eaves to secure the same to the wall and support the weight lugs are also
formed on or attached to the upper portion of the pipe above the eaves to enable
the same to be secured to a chimney or other structure or for receiving guy wires or
stay rods. The upper extremity of the said tube is provided also with suitable
perforations or lugs to enable the wire cover to be attached to the ventilating shaft
without the aid of solder.

Improvements in and connected with Soil Pipes, and Ventilating
Shafts therefor.
We, WILLIAM JAMES FREEMAN and EDWIN FREEMAN, both of 99 York
Road, Battersea, in the County of Surrey, Sanitary Engineers, 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:-
The object of this invention is to simplify the connection of the outgo pipes from
water closets and the like to the vertical soil pipe and to facilitate the connection of
the ventilating shaft thereto and to the building.
Now according to one method of carrying out the first part of our invention we
dispense with the ordinary lead tee piece to which the outgo pipe is usually attached
and use instead thereof a pipe constructed of tinned iron or copper the said pipe
having an orifice at one side thereof to admit of the insertion of the outgo pipe from
the trap the edges of which orifice may be beaded or slightly flanged the pipe
terminating in a socket at the top and a spigot at the bottom thereof or the ends of
the pipe may be flanged if desired. We may also form lugs on the pipe to enable
the same to be secured to a wall or other structure.
Instead of the pipe hereinbefore mentioned we may form the same of iron brass
copper or gun-metal lined with lead in which case the iron brass or other tube may
be beaded or slightly flanged at the bottom and the lead lining turned over it and
also tafted into the socket end the metal tube being tinned round the orifice to
enable the branch joint to be securely wiped.
According to a modification of our invention we provide brass or gun metal
thimbles or casings one of which may be made with a socket and the other with a
flange.
These thimbles or casings are thoroughly tinned inside and placed in a mould and
the ordinary lead tee or connecting piece cast inside them when cool the casings will
be securely attached to the lead.
By means of these improved connections we are enabled to caulk all soil pipe
joints with lead if required.
The other part of our invention relates to a new terminal pipe for the ventilating
shaft which consists of a pipe of cast iron or other suitable material of sufficient
length to reach to the minimuin regulation height above the eaves and having a
double curve of large radius therein to enable the upper end of the said pipe to
stand clear of the eaves. Lugs may be formed on or attached to the portion of the
pipe below the eaves to secure the same to the wall and support the weight.
Lugs may also be formed on or attached to the upper portion of the pipe above
the eaves to enable the same to be secured to a chimney or other structure or for
receiving guy wires or stay rods. The upper extremity of the said tube is provided
also with suitable perforations lugs or sockets to enable the wire cover to be
attached to the ventilating shaft without the aid of solder.
And in order that our said invention may be fully understood we will proceed to
explain the same with reference to the accompanying drawings in which :-
Figure 1 represents a partial section of our improved connection for soil pipes
constructed according to this invention.
Figure 2 is front view of same shewing orifice.
Figure 3 is section of same shewing outgo pipe attached thereto.
Figure 4 shews tee piece cast with thimbles thereon.
Figure 5 is side view of our terminal pipe for soil pipe ventilating shafts,
Figure 6 is front view of same.
Figure 7 plan of same.
Similar letters of reference are used wherever possible to denote the same parts.
u is the connecting pipe made of tinned iron or copper having an orifice & in the

page_text: side thereof as shewn in Figure 2 to admit of the insertion of the outgo pipe this
pipe is preferably provided with a socket c at its upper end but when the pipe is
fixed in a horizontal position the said socket may be dispensed with.
According to another method of carrying out this part of our invention instead
of tinning the whole of the pipe a we form the same of iron copper or other suitable
metal and tin round the edge of the orifice only and line the said tube with lead f
as shewn in Figure 1 and we turn over the lower edge of the said lining as shewn
at g Figure 1 and taft the upper portion of the said lining into the socket e.
In
some cases we may dispense with the tinning altogether and make the orifice b
somewhat larger than the outgo pipe and wipe the branch joint on to the lead
lining as shewn in Figure 3. The edges of the orifice are bevilled to facilitate
the wiping of the branch joint to the lining f
According to the third method of carrying out our invention we provide brass or
gun metal thimbles or casings h h whereof one is provided with a socket c and the
other may be provided with a flange k.
These thimbles after being thoroughly tinned inside are placed in a mould and
an ordinary lead tee piece or connecting pipe l cast inside them. When removed
from the mould the thimbles will be found firmly attached to the lead.
The lead lining may also be cast into the pipe a in a similar manner.
The terminal pipe for the ventilating shaft is preferably constructed of cast iron
having a double curve therein of large radius as shewn at Figure 5 to enable the
said pipe when fixed to be clear of the eaves of the building to which it is
attached.
Lugs e e may be provided at the lower end of the said pipe to enable it to be
attached to a wall or other structure and stand clear of the same so as to allow of
the joint between the ventilating shaft and the said terminal to be caulked with
lead nnnn are lugs having holes therein to enable the wire cover to be attached
to the top of the pipe o o are projections forming a dovetailed recess to receive &
loose socket piece to which may be attached guy wires or stay rods.
In soil pipes fitted with connections constructed as hereinbefore described every
joint may be caulked with lead if required without damage to the lead portion of
the pipes.
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 :-
1. The improved connection for soil and ventilating pipes having an orifice
therein to receive the outgo pipe and spigot and socket ends all substantially as
hereinbefore specified.
2. The improved connection for soil pipes and ventilating shafts constructed of
brass or other suitable metal having an orifice therein to receive the outgo pipe
and a lead lining substantially as hereinbefore specified.
3. The improved connection for soil pipes and ventilating shafts constructed of
brass or other suitable metal having an orifice therein to receive the outgo pipe
spigot and socket ends and a lead lining substantially as hereinbefore specified and
shewn by Figures 1 and 3 of the accompanying drawings.
4. The improved tee piece or connecting pipe having metal thimbles or casings
attached thereto substantially in the manner herein before specified and shewn by
Figure 4 of the accompanying drawings.
5. The improved terminal pipe for ventilating shafts substantially as hereinbefore
specified and shewn by the accompanying drawings for the purposes stated.
