PROVISIONAL SPECIFICATION.
Composite Water Tight Pipe Joints.
I HENRY MALCOLM RAMSAY, of 11 Amyand Park Road, Twickenham, in the
County of Middlesex, Surveyor do hereby declare the nature of this invention to be
as follows:-
This Invention consists in manufacturing specially formed flanged stoneware or
other pipes, designed for the reception of the requisite material and the construction
of composite joints, by running a casting molten asphalte, liquid Cement, Concrete,
or, other water resisting substance, in such form and manner as to make when jointed
together a perfect water tight joint.
In carrying out my Invention (the arrangements of which will admit of diversifi-
cation relatively to the particular class and size of pipe to which the invention may
be applied), the pipes are manufactared as before described and the joint faces are
formed by running or casting ferrules and linings in the above mentioned materials
on the spigots and in the sockets of the pipes, either in a straight or curved taper or
square shaped form, by means of suitable male or female moulds turned or otherwise
prepared and adapted to produce the said ferrules and linings in the forms indicated,
with the addition in the case of large pipes of a metal or composite tongue or key to
give increased solidity and security to the joint.
The sockets and spigots of the pipes when used in either of the above forms are to
be coated or dressed with Gas Tar, Tallow, white lead, or, other lubricating body and
being inserted one into the other and pushed home together will produce a joint which
will resist all water pressure and remain water tight.

COMPLETE SPECIFICATION.
Composite Water-tight Pipe Joints.
I, HENRY MALCOLM RAMSAY, of 11, Amyand Park Road, Twickenham, in the
County of Middlesex, Surveyor, 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 consists in manufacturing specially formed flanged stoneware or
other pipes, designed for the reception of the requisite materials and the construction
of composite joints, by running or casting molten metal or asphalte liquid cement,
concrete or other water-resisting substance in such forms and manner as to make when
jointed together a perfect water-tight joint.
In carrying out. my Invention (the arrangements of which will admit of diversifi-
cation relatively to the particular class and size of pipe to which the invention may
be applied,) the pipes are manufactured as before described and the joint faces are
formed by running or casting ferrules and linings in either of the above mentioned
materials, on the spigots and in the sockets of the pipes, as drawings Nos. 1. 2. 3 & 4,
or in separate circular blocks for attachment thereto all by means of suitable male and
female moulds turned or otherwise prepared and adapted to produce the said ferrules
and linings in a spiral form.
The moulds being made of plaster of Paris or other suitable material, or mandrils
in cast iron and the said ferrules and linings may be further secured by providing
in the periphery of the pipe two or more apertures into and through which the fused
or liquid material forming the ferrules and linings will pass and form an immovable
key or the periphery of the pipe may be serrated on socket and spigot faces or with a

page_text: core (as shown by dotted lines on Drawing No. 2) to the thread of the screw, and in this
way form a key for binding or securing the fused or liquid material to the stoneware
or other pipe faces and thus prevent any stripping of the screw formation.
the materials of which the castings forming the screw ferrules and linings (block or
otherwise) forming the joints are made may be varied in proportion according to
circumstances, and as may be suitable for the use to which the pipes are intended and
the said ferrules and linings in either case may be formed of the fine V thread
pattern the coarse V the round end the square or other form of screw or pitch
desired as Drawings Nos. 1. 2. 3. 4 which are given as examples, or, if in metal may
be cut from the lathe from a plain casting or otherwise, the Invention not being
limited to the materials of which the joints are composed or the form of screw or
flange which may be varied according to the size or the material of the pipe to which
it is applied or adapted.
or
Where the castings forming the screw ferrules and linings are formed
manufactured and consist of separate circular blocks as before described they are to
be attached or fixed on the spigot and in the socket of the pipes by the use of hot
bituminous mastic or other sufficient material or any of the castings may be con-
structed to form a core to be bushed with a thin coating of metal in a spiral form
as Drawing No. 2.
The sockets and spigots of the pipes when used in either of the above forms are
to be coated or dressed with gas tar, tallow, or other lubricating body or substance
and being inserted one into the other and screwed up home will produce a joint
which will resist all water pressure and remain water-tight.
And in order that my Invention may be more readily understood reference is
made to the accompanying drawings in which I have shown and illustrated the
general arrangement of the forms and manner of screw-jointing by which the
Invention is carried into effect.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed, I declare that what 1
claim, is.
1. The construction of specially formed flanged pipes with or without a core for
thread of screw in manner before mentioned and for the reception of the ferrules
and linings as above described.
2. The construction of screw linings and ferrules either as castings onto the spigot
or into the sockets or as castings in separate blocks for attachment thereto or as
castings formed with a core for the reception of spiral inetal facings together forming
male and female screws, in the manner and for the purposes above described.
3. The construction of stoneware or other pipes with joints in a spiral or screw
form for the purpose of screwing same together in any position where the pipes may
be used.
