WILLIAM BECKETT, Land Agent, Oulton, Tarporley County of Chester, WILLIAM
CLIFF, Manager of Lime Works, Astbury Congleton, County of Chester, do hereby
declare the nature of our invention for ECONOMICALLY BURNING LIMESTONE,
BRICKS AND PIPES AND SUCH LIKE WARE OR MATERIALS, to be as follows:-
By applying and utilizing the Exhaust heat from ordinary lime kilns by passing
it through flues into an oven or kiln in which we have for sometime past burnt
limestone, Bricks, and pipes of a very superior qality without fuel of any
description.
The ordinary open kilns are covered with fireclay slabs placed in iron frames on
wheels running upon iron rails each side the kilns, see plan.
This process does away with any possibility of nuisance from smoke or fumes
arising from the process of burning limestone, Bricks &c and meets every sanitary
requirement.
The application of the covers, flues and chimney to the old kilns resulted in a
saving of 20% in fuel, the new oven not requiring any fuel.

Chester, WILLIAM BECKETT, Land Agent, Oulton Park, Tarporley, in the County
of Chester, WILLIAM CLIFF, Manager of Lime Works, Astbury, Congleton, in the
County of Chester, do hereby declare the nature of our invention for CON-
STRUCTING KILNS AND OVENS FOR BURNING LIMESTONE, BRICKS, PIPES, & OTHER
LIKE MATERIALS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The top of the ordinary open Lime burning kilns to be covered with fire clay
slabs placed in wrought iron frames (on wheels) so that no part of the iron work is
exposed to the heat of the kilns, the covers being mounted on iron rails, placed
cach side the open mouth of the kilns, for removing off and on at will.
The ovens to be constructed either square or circular at a convenient distance
from the open kilns.
The walls of the oven not to be less than two feet thick, and the dome not less
than fourteen inches thick, of stone or common bricks with a fire brick lining.
The pocket walls, of fire bricks, built round the oven, (with the exception of the
door way).
The floor of the ovens to be fire bricks on edge laid so as to admit of a free
current or draught through to the Well in the centre from which a flue is
_ constructed to carry the draught to a chimney.
From the open kilns a flue is constructed which at a convenient distance
..divides into two or more branch flues to distribute the heat from the open kilns
uniformly through the ovens.
Fig 1 and fig: 3 on accompanying drawing at A A A A shew fire clay slabs in
wrought iron frame B fig: 3,-which by means of wheels C run on rails D
'placed on each side of the kilns E E. These slabs form lids for the purpose of
_confining the heat and preventing its escape in the ordinary way, also of promoting
more effectual combustion, thus removing a possible nuisance and effecting a
considerable saving in fuel.
When the oven F is at work the heat and smoke pass into the flues G G which
divide into two or more flues H H H H so placed as to uniformly distribute the
heat in oven F:
The arrows shew the direction of the heat current.
Dampers J. Jare placed in the flues G G and when the oven F is not at work the
dumpers J Jare closed and the dampers K K in flues LL are raised, the smoke and
heat escaping to the chimney M. These dampers (fig: 4) are formed of fire-
clay slabs N working in fire clay grooves O by means of a balance weight and
pulley P.
The flues are constructed of bricks, or stone, lined with 44 inch firebricks.
The pocket walls of the oven Q (fig: 1) are so constructed that the heat from
the flues is distributed so as to uniformly burn the materials in every part of
the oven.
The construction of the oven floor R allows the free passage of the waste heat to
the well S in the centre; the heat is conveyed from thence by the flue T to the
chimney M.

page_text: 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
The method of utilizing the waste heat from Lime Kilns, or the combination or
construction of kiln and oven as and for the purposes described.
