Year: 1862

page_text: LETTERS PATENT to John Platt, of Oldham, in the County of Lancaster,
Mechanical Engineer, and William Richardson, of the same Place,
Mechanical Engineer, for the Invention of "IMPROVEMENTS APPLICABLE TO
Deer RTR ÅRTICLES OR EARTHENWARR"
Sealed the 24th February 1863, and dated the 4th September 1862.
PROVISIONAL SPECIFICATION left by the said John Platt and William
Richardson at the Office of the Commissioners of Patents, with their
Petition, on the 4th September 1862.
We, JOHN PLATT, of Oldham, in the County of Lancaster, Mechanical
Engineer, and WILLIAM RICHARDSON, of the same Place, Mechanical Engi-
neer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO THE BURNING OF BRICKS, TILES, AND OTHER ARTICLES OF EARTHEN-
WARE," to be as follows:-
Our Invention consists in a method of heating a filled kiln in a preparatory
manner, and this we accomplish by transferring thereto the heat from a
separate kiln in which the burning of the bricks or other articles has been
effected. For this purpose we employ a blast of air, which passes from the
top of the heated kiln to the lower part of that in which the articles to be
burnt are placed.

by the said John Platt and William Richardson in the Great Seal
Patent Office on the 4th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PLATT, of Oldham, in the County of Lancaster, Mechanical Engineer, and
WILLIAM RICHARDSON, of the same Place, Mechanical Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of September, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her beirs and successors, give and grant unto us, the
said John Platt and William Richardson, Her special license, that we, the
said John Platt and William Richardson, our executors, administrators,
and assigns, or such others as we, the said John Platt and William
Richardson, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention of "IMPROVEMENTS APPLICABLE
TO THE BURNING OF BRICKS, TILES, AND OTHER ARTICLES OF EARTHENWARE,”
upon the condition, amongst others, that we, the said John Platt and
William Richardson, by an instrument in writing under our hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Platt and William Richardson,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawing (that is to
say)-
Our Invention consists in a method of heating a filled kiln in a preparatory
manner, and this we accomplish by transferring thereto the heat from a
separate kiln in which the burning of the bricks or other articles has been
effected. For this purpose we employ a blast of air, which passes from the
top of the heated kiln to the lower part of that in which the articles to be
burnt are placed,

page_text: The accompanying Drawing illustrates how this principle may be carried
into operation.
A, B, C, are three kilns, or there may be two only, or any greater number.
Supposing that the bricks or other articles have been burnt off in that shewn
at A, and the moulded articles intended to be burnt are placed in B, we adapt
a pipe a to one of the ordinary flue apertures, and a pipe 6 to the fire-holes of
the two kilns, luting them with clay or otherwise making a joint. The pipe a is
then placed in communication with a fan or other blowing apparatus, whereby
a current of air is caused to pass through the kiln A and into the kiln B,
carrying with it the heat retained by the burnt bricks or other such articles;
and thus a preparatory heating of the said kiln is effected. The fan or other
such blowing apparatus may be fixed in any convenient permanent situation, or
it may be mounted on the top of the kilns and be caused to travel thereon, so as
be placed in the most direct connexion with the pipe a. The complete burning
in the kiln B having been effected, the pipes a, b, may be transferred, so as
to afford a communication between B and C, and so on through any desired
number. The above-mentioned travelling blowing apparatus being in such
an arrangement a convenient method of applying the blast, but our Invention
is, of course, equally applicable when two kilns only are employed.
Having thus described and ascertained the nature of our said Invention,
and the manner of carrying the same into effect, wo desire it to be understood
that we claim as secured to us under the above in part recited Letters Patent
and for the purpose above set forth, causing the heat of one kiln to be trans-
ferred to another by means of a blast of air which passes from the top of the
heated kiln to the lower part of the other.
In witness whereof, we, the said John Platt and William Richardson,
have hereunto set our hands and seals, this Third day of March, in
the year of our Lord One thousand eight hundred and sixty-three.
