HUGH MORUER, of Glasgow, in the County of Lanark, North-Britain,
"IMPROVEMENTS IN COOKING RANGES,"
This Invention which relates to improvements in cooking ranges, has special
reference to improved ventilating arrangements or devices to be fitted to such
ranges mainly for the purpose of carrying off vapours and odours arising from the
cooking operations.
The improvements as applied in connection with open and close fire ranges,
consist in fitting the ordinary open fire arrangement to a rectangular or other
shaped flue formed by plates projecting a few inches forward from the back or cove
plates of the range, and extending upwards to and through the usual smoke plate
as far as may be convenient. In the front plate of this flue, above the open fire hood
or jointed plates, is formed a grating which may be rectangular, circular, or of other
form, and behind this fixed grating is fitted a movable grating, which is operated
by a knob or handle outside, and may be made to slide vertically or horizontally,
or to turn on a centre, to cover or uncover, partially or entirely, the grating or
openings in the front plate of the flue. The extent of opening of the grating may
thus be varied to provide effective ventilation without interfering with the draft.
For convenience in cleaning out the flue, the front plate of the open fire arrange-
ment, or the ventilating grating only, may be hinged or otherwise fitted movably.

The improvements as applied in connection with open and close fire ranges,
consist in fitting the ordinary open fire arrangement to a rectangular or other shaped
flue formed by plates projecting a few inches forward from the back or cove plates
of the range, and extending upwards to and through the usual smoke plate as far
as may be convenient. In the front plate of this flue above the open fire hood or
jointed plates, is formed a grating which may be rectangular, circular, or of other
form, and behind this fixed grating is fitted a movable grating which is operated
by a knob or handle outside, and may be made to slide vertically or horizontally, or
to turn on a centre to cover or uncover partially or entirely, the grating or
openings in the front plate of the fiue. The extent of opening of the grating may
thus be varied to provide effective ventillation without interfering with the draft.
For convenience in cleaning out the flue, the front plate of the open fire
arrangement, or the ventillating grating only, may be hinged or otherwise fitted
movably.
My said Invention is illustrated by the accompanying Drawings in which
figure 1 is a transverse vertical section, and figure 2 is a front elevation of a
cooking range or kitchener to which a modification of the improvements is
applied.
The range is of ordinary construction, but is fitted with a rectangular vertical
flue A formed by plates A, A, extending forward from the usual cove plates B of
the range and passing up through the smoke plate C. In the front plate A' of this
flue, in close proximity to the smoke plate C, is cast or formed a grating D through
which the fumes or odours of the cooking operations are carried into the flue A.
At the back of the fixed grating D is a sliding or other movable grating D'
sliding in guides & in the plate A', and this grating D' is connected to a knob or
handle D passing out through a slot in the fixed grating to the front, so that the
back grating may be brought more or less over the openings in the front one to
regulate the extent of opening, or to close the openings altogether.
Instead of making the gratings rectangular as shown, they may be circular, and
the movable portion may be made to turn on a central stud to regulate the extent
of opening.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I declare that what I claim is,-
The arrangement and combination in a cooking range of a grating formed or
fitted in a flue at the back of the range as herein described and illustrated, and for
the purpose set forth.
In Witness Whereof, I, the said Hugh MoRuer, have hereunto set my hand
and seal this Twelfth day of April, in the year of our Lord One
thousand eight hundred and eighty three:
