MR. JAMES GRELLIER’s (BARKING), for 
a Building of a peculiar Construction, 
for the purpose of burning Coke and 
Lime, whereby the superfluous Heat of 
the Fire used in burning Coke is ap- 
plied to burn lime, and also whereby such 
Sire may be rendered perpetual. 
The kiin is made into one or more 
compartments, chambers, &c. of the 
form of a2 common coke-oven, or of any 
other form and size, which may he adopt- 
ed for burting Boal, and converting the 
game into coke. The coal is burnt se- 
parately from the lime-stone; one or 
more of the compartments are made co- 
nical, or cylindrical ; and from them all 
flues proc eed, in order that the heat from 
the coke-oven may, act upon the lime- 
stone, or other calcareous bedies, and 
convert them into lime.” ‘(it is ex- 
pedient and necessary,” the patentee 
says, ‘that the coke-oven or ovens 
should be so placed or disposed, that 
the draught from the flues thereof may 
proceed upwards through the said lime- 
stone, or otaer calcareous bodies, with 
sufficient rapidity and effect; and that 
the space or spaces which, in my said in- 
vention, are appropriated to answer the 
purposes of the lime-kiln, should be duly 
disposed above the said flues. And the 
said flues may be made to enter into the 
Jime-kiln, threvgh the bottom or floor 
thereof, the lime being prevented from 
descending or subsiding as low as the 
said bottom or floor, by an arched 
grating or support, constructed of iron 
bars, or of brick work, or other proper 
materia! ; or, otherwise, the said flues 
may communicate through the sides of 
the said compartment, and by that 
means communicate the heat to burn or 
ignite all the lme-stone, or other calca- 
reous bodies, which may lie, or be dis- 
posed above the level of the said places 
of communication. And in that con-

struction, before described, wherein the 
ime is supported by an iron grating, or 
other structure, the burned lime is to be 
drawn (after the coke-ovens have been 
discharged) through doors or quarters 
made just above the said iron grating, or 
other structure. And in the other con- 
struction before described, wherein the 
flues communicate through the sides of 
the compartment, containing the lime, ‘3 
continue the said compartment, space, ~ 
or chamber, several feet below the com- 
munications from the said flues; and do 
draw out the burned lime at the bottom, 
in the same manner as is done with regard 
to a commonlithe-kiln. And acccrdingly, 
in consequence of the peculiar construc 
tion of my said. building, called the union 
aid perpetual kiln, it 1s practicable and’ 
easy to charge the said compartments, 
spaces, or chambers, intended to answer 
the purpose of coke-ovens, repeatedly with 
coal, for the purpose of Converting the 
saine into coke, and to charge the com- 
partinents, spaces, or chambers, intended 
to answer the purpose of a lime-kiln, or 
kilns, repeatedly with lime-stone, or 
other calcareous bodies, for the purpose of 
converting the same into quick-lime ; and 
also to draw out the said coke and quick- 
line at the proper periods, so as to con- 
tinue the said operations of coke-making 
and lime-burning perpetually during any 
length of time which may be required, 
And, lastly, [do declare, that although po- 
Sitions, situations, and dimensions, of the | 
part of my said kiln or building, may be va~ 
ried, yet I do give the preference to cokes 
ovens of an elliptical form, so disposed 
in the lower part of a circular building,’ 
that the longest diameters of the ellipses’ 
may respectively lie in radii, in one of, 
the horizontal sections of the said build- 
ing; and the mouths of the said ovens — 
may open externally, and the flues may~ 
communicate internally with one lime- 
kiln, having the axis thereof perpendi- ; 
cular to the horizon, and coincident with, 
the axis of the building itself.’ je
