IMPROVEMENTS IN FIRE GRATES AND STOVES
Year: 1885

page_text: We JOHN WILLIAM LEWIS of 65 Albion Street, Leeds, Engineer, and CHARLES
WINDSOR RAWLINGS of 9 Edwin Road Hyde Park, Headingley, nr Leeds, Stove
grate maker, both in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN FIRE GRATES AND STOVES," to be as follows:-
The object of our invention is to construct fire grates and stoves, so as to obtain
the greatest possible heat with the least possible fuel, and for the prevention of
smoke.
I construct my fire grate and stoves totally of fire brick terra-cotta or other
material of a similar character, the back of the fire stove projects forwards in one
piece and forms the front flue, it then passes backwards towards a second or back
flue or combustion chamber thus forming a division between the front and back
flues, the back is also perforated immediately behind the fire basket, at that portion
of the back where it projects backwards towards the back flue or combustion
chamber is a register door for diverting the draught, the action is as follows:-
when intense combustion is required the register door in the front flue is closed,
the products of combustion pass into the back flue or combustion chamber through
the perforations, when a less intense combustion is required the register door is
wholly or partially opened, and the products consequently allowed to pass up both
flues, the register door is operated by a chain, pulley, or slide as suitable. The
front of the grate projects forwards in front of the fire basket and may be seg-
mental or semi circular in form, so as to allow of greater projection of the head
into the room, the grate and the pierced fire brick back are constructed so as to
allow them to be drawn out to allow of renewal without disturbing the other parts
of the fire place.

page_text: Fig. 2, is a vertical section of Fig. 1.
Fig. 3, is a reduced sectional plan of Fig. 1, through the line A. B.
C is the front fitting of the grate or stove, D is the back, E, E, are the sides
which are secured together in one compact piece by bolts F, F, and are made totally
of fire brick terra cotta or other suitable material of a similar character, the back
of the fire stove D projects forwards in one piece and with the sides E, E, forms
the front flue at G. it then passes backwards at H. towards a second or back flue J,
or combustion chamber, thus forming a division between the two flues, the fireback
is also perforated at K, these perforations can be opened and closed at will, by a
slide or valve L; at that portion of the back H, which passes backwards is
a register door M for diverting the draught, The front of the grate N projects
forwards in front of the fire basket and may be of segmental, semicircular or other
shape, so as to allow of greater projection of the heat into the room the grate is
constructed so as to allow it to be drawn out, the pierced portion of the fire back
is in sections P. R. S. T. which can be taken out to allow of renewal, without
disturbing the other part of the fire place, the action is as follows:-When intense
combustion is required the register door M. in the front flue is closed, and the slide
or valve L opened, the products of combustion pass into the back flue or combus-
tion chamber J through the perforations K.
When a less intense combustion is required the register door is wholly or partially
opened, and the slide or valve L wholly or partially closed, and the products of
combustion consequently allowed to pass up either one flue only, or both flucs;
the register door and the slide or valve are operated by the slide rod U, and
connections V. W. or other such convenient connections as may be found most
suitable.
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
(1.) In fire places and stoves the combination of the back and front flues, and
the means whereby the products of combustion can be diverted and regulated as
shewn and described.

page_text: (2.) The provision in the perforated back of the moveable pieces P. R. S. T. to
allow of renewal without disturbing the main portion of the stove as shewn and
described.
(3.) The formation of the back and side sections, and the means of securing
them by bolts F. F, so as to make one compact piece as shewn and described.
(4.) The general arrangement and construction of stoves as shewn and described.
