I, WILLIAM HASSALL, of Meadow Lane, Beeston, in the county of Nottingham,
Agent, do hereby declare the nature of my invention for AN IMPROVED
COMPOSITION OR CEMENT SPECIALLY APPLICABLE FOR USE IN JOINTING STONEWARE
CONCRETE OR LIKE PIPES," to be as follows:-
This invention is designed to provide a composition or cement that may be
readily used for casting linings for stoneware or other like pipes or for forming
collars round the same by means of moulding, or for forming mouldings or
ornamental work for building or like purposes.

For use in making castings for lining stoneware pipes or other like purposes
I mix oxide of iron taken from the gas purifiers or other like sources (which
contains a large proportion of free sulphur) with gas-tar or pitch or both and to
this mixture I add pure sulphur in such quantity as may be required together with
quick lime, limestone in lump or powder and silicious sand.
For forming collars for pipes or for other moulded work I use a large proportion
of crushed limestone and limestone dust.

I WILLIAM HASSALL of Meadow Lane Beeston in the county of Nottingham
Agent 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 is designed to provide a composition or cement that may be
readily used for casting linings for stoneware or other like pipes, or forming
collars round the same by means of moulding or for forming mouldings or
ornamental work for buildings or like purposes.
For use in making castings for lining stoneware pipes or other like purposes
where such composition or cement is applicable I take oxide of iron from gas
purifiers (which oxide of iron contains a large proportion of free sulphur) say in
the proportion of one ton, and mix. the same with gas tar or pitch (or both) say in
the proportion of seven hundredweight. To this mixture I add say one ton of
commercially pure sulphur and also add say, half a hundredweight of quicklime or
limestone in lump or powder, or for the latter materials I may substitute silicious
sand or ground slag.
For forming collars for pipes or other moulded work I use a larger proportion of
the lime limestone crushed or in powder or of the silicious matter.
It is obvious that these proportions may be varied according to the nature of the
work required and in many cases this can only be found by experiment.
For instance I may add to a mixture of tar sulphur lime or silicious matter (this
mixture being well known and not claimed by ine) a larger proportion of spent
oxide of iron than of sulphur or vice versa.
By the use of the spent oxide which contains free sulphur I can reduce the
quantity of sulphur necessary to give such compositions or cements the required
consistency and so reduce the cost of the same.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The use in making compositions or cements containing gas tar or pitch lime
limestone or silicious matter as described, of spent oxide of iron taken from gas
purifiers substantially as and for the purpose described.
