PROVISIONAL SPECIFICATION.
Improvements in Pipes and Pipe Couplings or Connections for Sewers,
Drains, and other purposes.
I, ALFRED CUNDY TREW, of 16, Clarkson Street, Ipswich, in the County of
Suffolk, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in pipes of all kinds and the method
of jointing and coupling together, the object of the improvement being to secure
a water tight connection in a more simple manner than hitherto. For this
purpose I construct or form upon the spigot end of the pipe a projecting ring or
collar with one edge slightly undercut, namely the edge nearest the pipe joint or
connection. In place of the usual socket I purpose constructing in cement,
stoneware, or terra cotta, or the like materials a loose double length, half height
socket or coupling, shaped or moulded to fit in part the underside of the pipes
also hollowed out in part to allow clear space for the projecting ring or collar on
each end of the two pipes proposed to be coupled together, so that when the ends
of the two pipes are placed together within the mould or coupling, and cement or
other suitable material is filled into the interstices the two pipes become locked
into position, and the internal faces of the pipes are
level with each other thereby maintaining a free passage for
liquids and other matter passing through the pipes. When the ends of two
pipes have been placed together as herein before described, the joint can be com-
pleted by filling in the space between the two projecting rings or collars with
cement or other suitable material according to the substance from which the
pipes are made.

Improvements in Pipes and Pipe Couplings or Connections for Sewers,
Drains, and other purposes.
I, ALFRED CUNDY TREW, of 16, Clarkson Street, Ipswich, in the County of
Suffolk, 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 improvements in pipes and pipe couplings or con-
nections for sewers, drains and other purposes, the object being to secure a water-
tight connection in a more simple manner than hitherto.
According to the invention I provide a kind of half socket or coupling which

page_text: is of suitable material such as cement, brick, iron, stoneware, terra cotta, etc.,
and is shaped or moulded internally to fit the underside of the two spigot ends of
the pipe sections to be coupled. Each pipe end is advantageously provided with
a collar or ring, the inside edge of which is slightly undercut.
In employing a pipe coupling of my improved construction the joint is made
as follows, that is to say, the two sections to be joined are laid in the half socket
or coupling with the adjacent ends contiguous and cement is poured into the
said half coupling so as to make the lower half of the pipe sections solid with
the half socket or coupling. The joint is completed by running cement around
the space between the two undercut collars or rings upon the ends of the sections.
In practice I find it advantageous to form the adjacent ends of the pipes with
V-shaped notches running around the said ends so that when the two ends are
placed together a recess is formed into which white lead, putty or the like can
be filled so as to form a good joint between the ends and prevent the entrance of
cement into the pipe; a strip of metal or the like can be embedded in the putty
or other material introduced into the annular recess thus formed.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure 1 is a side elevation of a coupling or connection constructed according
to the invention ⚫
Figure 2 is a plan thereof:
Figure 3 is a section on the line 3-3 Figure 1; and
Figure 4 is a longitudinal section of the coupling or connection.
a is the half socket or coupling, the said socket or coupling being, as above
described, made of suitable material such as cement, stoneware, terra cotta, etc.,
and being shaped internally, as shewn, to receive the ends of the pipe sections A, B,
and enclose the lower halves thereof. b, b are the collars or rings formed near
the ends of each of the sections A, B, the said rings or collars b, 6 having their
internal faces 61, 61 slightly undercut as will be clearly seen by reference to
Figure 4.
c, c are the V shaped notches formed in the contiguous ends of the sections
to be joined so as to form the annular recess adapted to receive putty, white lead
or other suitable material c¹ to form a good joint between the said ends and dis
a strip of metal or other suitable material which I advantageously embed in the
putty or the like introduced into the said annular recess.
To couple two pipe sections by means of my improved coupling I proceed as
follows, that is to say, the two sections A, B to be joined, are placed into the
recessed half coupling or socket with their adjacent ends in contact, as shewn in
Figure 1, and cement e is then run into the space between the said pipe sections
and the socket after which cement f is run into the space between the two
collars or rings b, b at the upper part of the pipes thereby making the pipe
sections and the socket into one solid mass when the cement sets. Where the
V shaped recesses are used in the ends of the pipes A, B, the putty or other
material is filled into the said recesses before the joint is made as above described.
It is to be understood that although I have illustrated my pipe coupling as
applied to connecting pipes of circular section, the said coupling can also be
employed for joining sections of oval or other usual section.
It will also be clear that my half socket or coupling can be advantageously
employed for ordinary pipe joints, that is to say, to the ordinary faucet and spigot
joint in which case the rings or collars b, b, are dispensed with.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A pipe coupling or connection
cement, stoneware or other suitable
