PROVISIONAL SPECIFICATION.
A New and Improved Method of Forming the Joints in Earthenware
and other Pipes.
We, JOHN JOHNSTON GREEN, of Prospect House, Church Street, Halifax, in the
County of York, Sanitary Engineer, and CHARLES LESLIE STIFF, of 18, Edmund
Street, Birmingham, in the County of Warwick, Manufacturers' Agent, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a new or improved method of forming the joints in
earthenware and other pipes, the object being to provide a simple and effectual
method of rendering the said joints watertight, and this is performed in such
manner that the pipes when first laid are allowed a certain amount of elasticity
thus enabling the pipes to bed themselves in and find a solid bearing.
66
In order to carry out our invention we lengthen the socket of the pipe and
at or near to the inner end of the socket we form in the usual manner, a Stanford,
composition, cement or any other suitable form of joint. On the spigot end of
the pipe at, or at a point near to, the edge of the socket, when the pipes are in
position, we cast or otherwise form an annular fillet or nug" of cement or
other suitable substance or material of such size or thickness as to nearly fill
the space between the spigot and socket of the pipes. Between this fillet and
the Stanford or other joint employed is left a cavity which we may fill in with
any suitable form of liquid cement introduced through a port hole formed for
that purpose in the socket of the pipe or we may employ any other form of
cement or filling as found most desirable. The outer sides of the fillet and socket
may be luted with clay. In some cases we may find it desirable to discard the
fillet or nug" in the socket.
By the above means an effectually watertight joint can be made, and further
it has the advantage of giving the pipes when first laid a little elasticity, thus
allowing them to find a solid bed.

page_text: Street, Birmingham, in the County of Warwick, Manufacturers' Agent, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a new or improved method of forming the joints in
earthenware and other pipes, the object being to provide a simple and effectual
method of rendering the said joints watertight, and this is performed in such
manner that the pipes when first laid are allowed a certain amount of elasticity
thus enabling the pipes to bed themselves in and find a solid bearing.
"
In order to carry out our invention we lengthen the socket of the pipe and
at or near to the inner end of the socket we form in the usual manner, a Stanford,
composition, cement or any suitable form of joint. On the spigot end of
the pipe at, or at a point near to, the edge of the socket, when the pipes are in
position we cast or otherwise form an annular fillet or 'nug" of cement or
other suitable substance or material of such size or thickness as to nearly fill
the space between the spigot and socket of the pipes. Between this fillet and
the Stanford or other joint employed, is left a cavity which we may fill in with
any suitable form of liquid cement introduced through a port hole formed for
that purpose in the socket of the pipe or we may employ any other form of
cement or filling as found most desirable. The outer sides of the fillet and socket
may be luted with clay. In some cases we may find it desirable to discard the
fillet or "
nug" in the socket.
"
In order to illustrate our invention, we will refer to the annexed drawings
wherein Fig. 1 shews a longitudinal section of a joint made according to our
invention. A and B are two fillets or 68 nugs
" of cement or other suitable
material forming a "Stanford or other form of joint to go between the two pipes C
and D. E is a fillet or
nug'
" of cement or other suitable material cast or
otherwise formed on the spigot C preferably of such a height or thickness as
nearly to fill the space between the spigot and socket as shewn and employed to
retain cement or composition F which may be liquid or otherwise introduced
through port hole G. H is a luting of clay or like plastic material to make
good the outer joint.
Fig. 2 shews a modification of our invention, in which we dispense with the
fillets or <<
'nugs" A and B and instead thereof employ two "nugs
" or fillets
such as L.
The fillets or "nugs" may be of any suitable cross section, and any suitable
number may be used either on the spigot or socket ends of the pipes.
By the above means an effectually watertight joint can he made, and further
it has the advantage of giving the pipes when first laid a little elasticity, thus
allowing them to find a solid bed.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is;-
The combination with a Stanford or other like joint for earthenware and other
pipes, of a fillet or fillets such as E, substantially as shewn in Fig. 1 and for
purposes set forth.
In earthenware and other pipe joints, the use therein of two or more fillets
such as L arranged substantially as shown in Fig. 2, and for purposes set forth.
