PROVISIONAL SPECIFICATION.
Improvements in and relating to the Jointing of Stoneware and
other like Pipes.
I. WILLIAM HASSALI. of Butt Lodge Woodville in the County of Leicester Pipe
Manufacturer do hereby declare the nature of this invention to be as follows:-
My present invention relates to improvements in the jointing of stoneware and like
pipes and more particularly to that class of pipe joints described in the Specification
of Letters Patent granted to one Walter Halsted Cortis Stanford numbered 4039 and
dated 8th of December 1873 and in joints described in the Specification of Letters
Patent granted to me the said William Hassall numbered 4357 and dated 4th of
March 1884 whereby linings or rings of molten cement or other suitable composition
are cast upon the spigots and within the sockets of the pipes by means of moulds.
In carrying out my present invention I form or mould the aforesaid linings or rings
in such a manner that instead of extending the whole length or depth of the socket,
they only occupy a portion (say one half or other convenient proportion) of the
length or depth of the socket leaving a space above or beyond such linings or rings
which I fill with Portland or other cement or composition and I may pour this in
by means of removable or fixed clay or other collars or I may fill it in in a plastic
state by means of a trowel or other fool or part of the cement may be poured in
the space by means of a collar and the rest. filled in in a plastic state by the use
of a tool thus making a perfectly tight and effective joint without using the plastic
cement between the rings or linings as described in No. 4357 of 1884 such rings or
linings being brought in contact.
When found desirable I may extend the socket of the pipe forming a hole or holes
in such extension and having placed a clay or other collar round the spigot end
of the pipe and close to the socket of the next pipe, run in liquid cement of any
uitable nature.
Dated this 25th day of September 1859.

COMPLETE SPECIFICATION.
Improvements in and relating to the Jointing of Stoneware and
other like Pipes.
I WILLIAM HASSALL of Butt Landge Woodville in the County of Leicester Pipe
Manufacturer 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:-
My invention relates to the jointing of stoneware and like pipes such as sewer
pipes and more particularly to such methods of forming joints as are described in the
Specifications attached to Letters Patent granted to Walter Halsted Cortis Stanford
numbered 4039 and dated 8th December 1873 and to Letters Patent granted to me
numbered 4857 and dated 4th March 1884, whereby linings or rings of molten
cement or other suitable composition or material are cast upon the spigots and within
the sockets of stoneware pipes by means of moulds.
My present invention is designed to provide an improvement in such joints and in
carrying it into effect I form or mould the linings or rings such as described in the
specifications referred to in such a manner that instead of extending throughout the
sockets of the pipes and occupying the whole of the space therein or nearly so they
are made so as to fill only a small portion or say one half of the socket leaving a

cement which may be poured through an orifice provided for the purpose or may be
filled in in a plastic state or the lower part may be poured and the upper part filled
in by means of a tool thus forming a perfectly tight and effective joint without using
the plastic cement between the rings or linings as described in 4357 of 1884 the rings
being brought into contact.
To pour in the liquid cement I may use either a removable or fixed collar of clay
or other suitable material which may wholly or partially surround the pipe.
Referring now to the accompanying sheet of drawings and to the figures and letters
of reference thereon.
Figure 1 is a longitudinal section through the spigot and socket ends of pipes
showing a joint made according to my invention without a clay collar and in this
view A is the spigot end of one pipe and B the socket of the next. C. D are the
moulded rings or linings fitting close together and E is cement in a plastic state filled
into the remaining portion of the socket by means of a tool.
Figure 2 is a similar section but in this construction a clay or other collar F is
formed round the end of the socket and the cement in a liquid form is poured through
a hole or orifice G in the socket end of the pipe.
Figure 3 shows an alternative method of pouring whereby the hole G is formed
in the clay or other collar F and divided by means of a wooden or other division the
cement flowing in the direction of the arrows and the clay collar F may wholly or
partially surround the pipe. Instead of a clay or like collar to retain the cement I
may form permanent rings on the socket and spigot ends of pipes extending the
socket for this purpose and place between them some suitable mastic compound so as
to make a perfectly fitting joint.
Figure 4 shows a joint made in this manner wherein H is the ring cast on the
socket and I that on the spigot of a convenient shape to interlock when forced home
and having mastic K placed between. The liquid cement L is poured through a
hole Gas before described.
Figure 5 shows a similar joint with straight rings H. and I.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
The method and means of jointing stoneware and like pipes substantially as herein
described and as illustrated by the accompanying drawings.
