COTIDIONAL DI BUIFICATION.
An Improvement in and appertaining to Stoves for Heating Rooms,
or for analogous purposes.
I, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-on-Tees,
in the County of York, Ironfounder, do hereby declare the nature of this invention
to be as follows:-
This invention is intended to effect an improvement in stoves for heating rooms
or the like when constructed with the upper or back part inclined or leaning.
towards a canopy or hood which overhangs the stove front.
The object in view is to provide a shield to prevent falling soot getting into the
fire grate and also by deflecting the course of the products of combustion as
they enter the chimney to cut off the admission of any great quantity of fresh air
to the chimney while the fire is alight whilst the inlet to the chimney may remain
open for ventilation at all other times without risk of soot or downdrafts entering
the room.
According to this invention a back hood or shield is fixed opposite to and
practically in contact with the front canopy to similarly overhang the stove back
to which it serves as a shield for the reception of all falling soot which would
otherwise drop into the grate and which it shoots instead into the space at the back
of the stove.
This back hood extends downwards to a point at which its lower edge or skirt
comes level or thereabouts with the top or ridge of the stove back with the result
that the products of combustion as they leave the fire are deflected over the top
or ridge of the stove back instead of reaching the chimney in uninterrupted
ascending currents.
Dated this 12th day of September 1893.

COMPLETE SPECIFICATION.
An Improvement in and appertaining to Stoves for Heating Rooms,
or for analogous purposes.
I, JOHN ROBINSON CROSTHWAITE, of The Union Foundry, Thornaby-on-Tees,
in the County of York, Ironfounder, 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 is intended to effect an improvement in stoves for heating rooms
or the like when constructed in such a manner that the back plate or brick which
is now usually inclined forward or leaning over the fire for the purpose of
deflecting the heat is brought near to a canopy or curtain which overhangs the fire.
The object in view is to provide a stove of this kind which will by means of its
construction prevent falling soot from getting into the fire grate and will also more
especially so deflect and control the course of the products of combustion as they
enter the chimney that whilst the inlet to the chimney remains open at all times
and when no fire is required is thus available for ventilation without risk of soot
or down draughts entering the room yet the usual escape of fresh air up the
TD27

page_text: chimney when the fire is alight is prevented and the inlet to the chimney fully
employed in carrying off the products of combustion.
In the drawing hereto annexed I have illustrated in vertical sectional view a stove
embodying the essential features of my invention in which the front canopy or
curtain a, the back part b and the grate c are of the ordinary construction and arrange-
ment and the precise form or design of stove indicated in the drawing is given for the
purposes of illustration only. But according to my invention the back hood or
shield d is fixed opposite to and practically in contact with the front canopy a to
similarly overhang the stove back b to which it serves as a shield for the reception
of all falling soot which would otherwise drop into the grate c and which it shoots
instead into the space at the back of the stove. This back hood extends down-
wards to a point at which its lower edge comes level or thereabouts with the top or
ridge of the stove back b with the result that the products of combustion as they
leave the fire are deflected over the top or ridge of the stove back b instead of
reaching the chimney in uninterrupted or continuously ascending currents, and
cross the opening to the chimney in the manner indicated by the arrows, that is in
about a horizontal direction to get under the edge of the back hood to which they.
so closely cling as to exclude from the chimney any air cooler and therefore denser
than these products of combustion. But in order to obtain the best results in this
respect and to intercept or exclude the admission into the chimney of the fresh
air of the room along with the products of combustion which only conduces to a
waste of fuel and disagreeable draughts in the room. I find that the ridge of the
back part 6 should be equi-distant or thereabouts from both the front and back
canopies or hoods a and d, leaving a clear space in stoves of the usual size for
currents of the escaping products of combustion of about three inches in width
between the ridge and the hood and so long as these conditions are practically
complied with the back part b may be set to any suitable angle or even be
perpendicular if so required.
.. :
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 :-
In the construction of stoves for heating rooms or for the like purposes, the use
in combination with the usual front canopy a, and back part b, of a back hood d,
substantially as and for the purpose as hereinbefore described with reference to the
accompanying drawing.
