PROVISIONAL SPECIFICATION.
Improvements in the Filling of Towers used in the Purification of
Acid, and for such like purposes.
We, HENRY LEWIS DOULTON, Potter, and LOUIS EDGAR SANCEAU, Corre-
spondent both of the Albert Embankment, Lambeth, in the County of Surrey, do
hereby declare the nature of this invention to be as follows:-
-
Ordinarily the towers used in the purification of acid and for such like purposes
are filled with lumps of broken coke. With such a filling the interstices between
the lumps are after a time liable to become choked and the efficiency of the tower
thereby becomes more or less impaired.
According to our invention we employ for the filling of the towers thick tiles or
bricks of pottery with holes formed vertically through them of such size relatively
to the size of the partitions left between them that when the blocks are placed one
above the other, breaking joint one with another in successive layers, the openings
through the blocks in one layer without being vertically in a line with the openings
in the blocks above and below them yet communicate with them in such a way
that all the openings in the blocks are in communication one with another.
The blocks may conveniently be about 9 inches square and about 4 or 5 inches
deep and each have four holes about 3 inches or more across formed through
them.
A filling composed of pottery blocks so formed will be very durable and not
liable to become choked.
Dated this 31st day of July 1894.

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:
Ordinarily the towers used in the purification of acid and for such like purposes
are filled with lumps of broken coke. With such a filling the interstices between
the lumps are after a time liable to become choked and the efficiency of the tower
thereby becomes more or less impaired.
According to our invention we employ for the filling of the towers thick tiles or

all the openings in the blocks are in communication one with another.
The blocks may conveniently be about 9 inches square and about 4 or 5 inches
deep and each have four holes about 3 inches or more across formed through
them.
A filling composed of pottery blocks so formed will be very durable and not
liable to become choked.
The drawings annexed show examples of blocks such as above described adapted
for forming the filling of a tower.
In the block shown in plan view in Figure 1 the holes through the block are
circular, in that shown at Figure 2 the holes are square.
Figure 3 shows in plan view how blocks such as shown at Figure 1 can be piled
one above another so that the holes in all the blocks communicate with one
another.
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:-
A filling for towers used in the purification of acid and for such like purposes
composed of earthenware tiles or bricks having holes formed vertically through
them so that when piled one above another and breaking joint the holes in one
communicate with the holes in the others substantially as described.
