PROVISIONAL SPECIFICATION.
Improvements in and relating to Domestic and other Fire Places.
I, JOSEPH THORNTON of Pilling Street, Burnley, in the County of Lancaster, Iron-
founder, do hereby declare the nature of this invention to be as follows:-
My invention consists in so constructing fire places, that the air and products of
combustion will escape through vertical slots or openings at the back of the fire into
an auxiliary flue, and from thence to the chimney. For this purpose, a semicircular
plate or grating is formed, preferably of iron, at the back of the fire place. This
plate or grating is inclined to the front of the chimney, so as to close the direct
passage, and compel the air and products of combustion to escape through the vertical
slots or openings in the plate or grate, into an auxiliary flue, behind the grating,
before their admission to the chimney. By these means, the heat is more intensified
and benificially distributed in the room or apartment in which the fire place is situated.
In front of the inclined grating is another plate or grating, of similar shape and form
as the other, to serve as a damper, and fit the outlino of the grating. To close or
partially close the slots or spaces in the grating, the damper plate is moved laterally
by means of a knob or button, so that the ribs of one plate or grating will cover, or
partially cover, the spaces of the other plate or grating to regulate the draft.

COMPLETE SPECIFICATION.
Improvements in and relating to Domestic and other Fire-places.
I, JOSEPH THORNTON of Pilling Street, Burnley, in the County of Lancaster, Iron-
founder, do 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 :-
This invention of Improvements consists essentially of a semicircular or inclined.
plate or grating, preferably of iron, situated at the back of the fire-place, having
behind or in front of it another plate of similar form and shape to fit the outline of
the other. Either one or other of the plates or grating is capable of being moved in
a lateral direction by means of a knob or button, so that the ribs of one plate or
grating may be made to cover or partially cover the spaces in the other to regulate the
draft and serve as a damper.
And in order that my invention may be properly understood, and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference; the same letters referring to the same
parts in the various figures. Fig. 1 is a front elevation, and Fig. 2 an end view in section
of a domestic fire place, constructed in accordance with my invention. Figs. 3 and 4
are detached views of my improved apparatus. A is preferably a cast iron plato
having vertical slits or spaces A' and blanks A². This plate is provided with
suitable legs B, by which it rests on brickwork or the like at the back of the
fire grate B; its upper end bearing against the chimney breast E, so as to require
no permanent fixing in the chimney flue F, and so as to be readily removed for
cleaning purposes.
Behind plate A is plate G having vertical slits or perforations G₁ and blanks G³,
and is of the same shape and form as to fit the curvature of plate A, and be capable
of sliding laterally, so that the slits or spaces A' in plate A may be wholly or
partially covered by the blanks G' of plates G to control the chimney draft.

page_text: In defective oven and boiler drafts the apparatus will be found of great advantage,
as by wholly or partially closing the direct passage to the chimney, the products of
combustion will be compelled to take the course of the boiler or oven flues, which may
for the time being be opened by the damper. To render the apparatus adjustable to
any width of fire-place, the plate A is provided with side wings H, which may be
made to expand or contract to the required width.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Plates A and G having slits or perforations capable of being opened or closed,
substantially as described for the purpose set forth.
2. The employment of side wings, substantially as described.
3. The general arrangement of the apparatus, shewn and described.
