PROVISIONAL SPECIFICATION.
Improvements in or connected with the Manufacture of Terra Cotta
and like Blocks for Building Purposes.
I, JAMES HOLROYD, of Burmantofts, Leeds, in the County of York, Ceramist,.'
do hereby declare the nature of this invention to be as follows:-
The object of my invention, is to construct architectural terra cotta and liko
blocks, in such a manner that they are not liable to become discoloured by any
salts or chemicals, which may be exuded from the concrete or other filling contained
in the interior of the block, or from the brickwork behind the terra cotta.
According to my invention, I coat the interior of the block, which holds the
filling of concrete or cement, with an impervious solution or glaze. When the
interior of the block has been thus coated, the concrete or other filling is inserted,
and the impervious coating effectually prevents any salts or other chemicals
contained in the filling, from passing through and discolouring the outside surface
of the block.
I prefer to apply the impervious glaze by means of a spray, which latter may be
obtained by any convenient spray producer, and a coating may be thus evenly
applied to the interior of the block, without waste.
Owing to the glazed interior of the blocks constructed according to my invention
not allowing staining from behind, any dirt which has settled on the surface may
be easily removed, and the terra cotta is thus made clean and to appear as new.
Dated this 13th day of November 1895.

and like Blocks for Building Purposes.
I, JAMES HOLROYD, of Burmantofts, Leeds, in the County of York, Ceramist,
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:-
The object of my invention, is to construct architectural terra cotta and like
blocks, in such a manner that they are not liable to become discoloured by any
salts or chemicals, which may be exuded from the concrete or other filling contained
in the interior of the block, or from the brickwork behind the terra cotta.

filling of concrete or cement, with an impervious solution or glaze. When the
interior of the block has been thus coated, the concrete or other filling is inserted,
and the impervious coating effectually prevents any salts or other chemicals
contained in the filling, from passing through and discolouring the outside surface
of the block.

easily removed and the terra cotta is thus made clean and to appear as new.
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 :-
-
1. Coating the interior of terra cotta and other blocks with an impervious
solution, thereby effectually preventing staining from behind, substantially as set
forth.
2. Applying an impervious glaze or other solution to the interior of terra cotta
building blocks, substantially as and for the purposes set forth.
