Complete Specification Accepted, 12th Oct., 1888
We, HUGH STEVEN of the firm of McDowall, Steven & Co. Ironfounders, Milton
Iron Works, Glasgow, and JAMES WALKER Foreman at said works do hereby declare
the nature of this invention to be as follows :-
--
Our Invention relates to domestic fire grates or "register" grates, and by one
improvement under our invention the canopy over the fire place, which in ordinary
register grates is cast or formed in a piece with the grate back, is separately cast
and attached by catches passing into or through orifices in the upper front part of
the grate back thus ensuring facility of production of ornamental forms and inter-
changeability of the canopies of different grates. In lieu of providing the ordinary
smoke register or flap damper at the back of the grate and pivotting it at a point
just over the fire grate we carry the back of the grate upwards and forwards in the form
of an inclined plate constituting part of or being attached to the casting of the
grate back this plate or inclined back serving to throw forward and outwards the
heat of the fire gases which pass up to and through a comparatively narrow outlet
between said plate and the canopy; and on the back plate we pivot a flap damper
which when closed covers said outlet and rests at the front edge on the back of the
canopy or back of the grate front instead of falling as usual on the back strap and
when opened rests nearly vertically on its supporting pivots on the back plate.

page_text: We HUGH STEVEN of the firm "of M:Dowall, Steven & Co. Ironfounders Milton
Iron Works, Glasgow, and JAMES WALKER, Foreman at said works 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 :-
Our Invention relates to domestic fire grates or register grates and is illustrated in
the accompanying drawings in elevation and vertical section at Figures 1 and 2
which show the improved grate in its completo form and in like views at figures 3
and 4 which show the canopy removed.
By one improvement under our invention the canopy A over the fire place which
in ordinary register grates is cast or formed in a piece with the grate back is separately
cast and attached by catches a passing into or through orifices in the upper front
part B of the grate back thus ensuring facility of production of ornamental forms and
interchangeability of the canopies of different grates whilst providing unusual facilities
for cleaning. In lieu of providing the ordinary smoke register or Hap damper at the
back of the grate and pivotting it at a point just over the fire grate we carry the
back of the grate upwards and forwards in the form of an inclined plate C constituting
part of or being attached to the casting of the grate back this plate or inclined back
serving to throw forward and outwards the heat of the fire gases which pass up to and
through a comparatively narrow outlet at D between said plate and the canopy A;
and on the back plate C we pivot a flap damper E which when closed covers said
outlet and rests at the front or upper edge on the back of the canopy or back of the
grate front instead of falling as usual on the back strap and when opened rests
nearly vertically as shown on its supporting pivots on the back plate.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The combination of parts constituting the improved register grate hereinbefore
described with reference to the annexed drawings.
2. A register grate formed with a removable canopy substantially as described.
3. A register grate having a back plate inclined upwards and forwards over the
fire place and terminating in a flap damper adapted to close against the canopy or
back part of the grate front substantially as described with reference to the drawings
annexed.
