page_text: We, HUGH STEVEN, of the Firm of M Dowall, Steven and Company,
Limited, Milton Iron Works, North Woodside Road, in the City of Glasgow,
and JOSEPH DANIEL DUCKETT, Manager with said Firm, do hereby declare the
nature of this invention to be as follows:-
This invention relates to kitchen ranges which are capable of being converted
from an open to a close fire, and vice versa, and has for its objects to render the
action of the movable parts easier and more positive than heretofore, and to so
construct the several parts as to enable these to be easily removed or replaced
without disturbing the setting or fixings of the range.
To that end we form the hood or canopy, which is of ordinary rectangular box
shape, with grooves or guides formed upon the under side of its roof which act
upon projecting studs on the upper edges of two pivoted doors when the hood is
drawn out so as to open or close these when an open or close fire is desired, the
two pivoted doors when shut forming the front plate of the hood when a close fire
is desired. The doors are pivoted on a frame fixed on the hot plate of the range,
the sole of this frame being flush with the hot plate, or when these improvements
are fitted to an existing range the lower pivots are secured in a bracket fixed to
the bot plate. Metal guide strips are fitted or fixed on the hot plate behind the
coving of the range and act on the sides of the hood or canopy when this is pushed
in or withdrawn, to guide it and prevent it from becoming jammed by badly
directed force. From the rear of and at the top of the fixed frame a projecting
arm with an angular spur at its end extends backwards and when the hood or canopy
is being pushed back to form a close fire acts on a damper pivoted on the roof of
the hood to raise this clear of the boiler flue, the damper falling automatically
into its proper position on roof of hood or canopy when this is withdrawn to form
an open fire.
The pivot pins of the front doors of hood or canopy as also the pivot pins of the
damper are of unequal length and acting in connection with a check in the upper
edges of the doors and a slot in the damper permit of the doors and damper being
removed without interfering with any of the fittings. The locking arrangements
also prevent displacement of the doors and damper when in their proper working
positions.

Improvements in Kitchen Ranges.
We, HUGH STEVEN, of the Firm of McDowall, Steven and Company,
Limited, Milton Iron Works, North Woodside Road, in the City of Glasgow,
and JOSEPH DANIEL DUCKETT, Manager with said Firm, 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 relates to kitchen or like ranges or stoves which are capable of
being converted from an open to a close fire, and vice versa, and has for its
objects to render the action of the movable parts easier and more positive than
heretofore, and to so construct the several parts as to enable these to be easily
removed or replaced without disturbing the setting or fixings of the range or
stove.
The invention is illustrated by the accompanying drawings,
Figure 1 being a front elevation of the range or stove as a close fire, Figure 2
a transverse vertical section, and Fig. 3 a plan of same.
Figure 4 is view corresponding to Figure 2, but shewing the position of the
various parts when the range or stove is used with an open fire.
Figure 5 is a plan of Figure 4.
Figure 6 is a vertical section of the hood shewing in dotted lines the method of
inserting the boiler flue damper in position and in full lines the locking action of
the spur upon the damper to prevent displacement when the damper is raised.
We form the hood or canopy A which is of ordinary rectangular box shape,
with angle strips forming a groove or guide B formed upon the under side of its
roof which act upon projecting studs C on the upper edges of two pivoted
doors D, D', when the hood A is drawn out or pushed back so as to open or close
these when an open or close fire is desired, the two pivoted doors D, D', when
shut as shewn at Figs. 1, 2 and 3, forming the front plate of the hood A when a
close fire is desired. The groove B is formed to act upon the doors D, D', in
such a manner as to close the door D a little earlier than the door D¹, and the
doors are so pivoted in relation to the groove B that when the hood is drawn out
the front face of each door is turned outwards from the fire and is thus protected
from the action of the fire and smoke. The doors D, D¹, are pivoted by means
of pins G in projections F on a frame F fixed on the hot plate E of the range or
stove. Metal guide strips H are fitted or fixed on the hot plate E, behind the
coving 1 of the range and act on the sides of the hood or canopy A when this is
pushed in or withdrawn, to guide it and prevent it from becoming jammed_by
badly directed force. From the rear of and at the top of the fixed frame Fa
projecting arm J with an angular spur K at its end extends backwards, and,
when the hood or canopy A is being pushed back to form a close fire, acts on a
damper L pivoted on the roof of the hood A to raise this clear of the boiler flue,
the damper L falling automatically into its proper position on the roof of the hood
or canopy A when this is withdrawn to form an open fire.
The pivot pins G of the front doors D, D', of hood or canopy A as also the
pivot pins L' of the damper. L are of unequal length and acting in connection
with a check D2 in the upper edges of the doors D, D₁, and a slot L² in the
damper L permit of the doors D, D¹, and damper L being removed without
interfering with any of the fittings. The doors D, D¹, are prevented from
displacement when closed by the upper edges of the doors engaging with the
projections F¹ on the frame F and in which the doors are pivoted; and the
locking arrangement of the damper L consists of the arm J entering a notch L
in the lower edge of the damper L when such is raised, to prevent displacement of
the damper L when in its proper working position as a close fire.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A combined close and open range the operative parts of which are constructed
and arranged or combined substantially as described.
2. In a range the combination with the hood or canopy having a groove on the
under side of its roof, of doors pivoted on the hot plate and arranged to open or
close by the movement of the hood substantially as described.
3. In a range the combination of a hood or canopy arranged to open or close
doors pivoted on the hot plate and a fixed spur adapted to operate a damper in the
boiler flue substantially as described.
4. In combination with a hood or canopy for ranges, pivoted doors, forming the
front plate of the hood when closed, each door having pivots of unequal length in
conjunction with a check to permit of the removal and insertion of the door without
disturbing the fixings of the range substantially as described.
5. In a hood or canopy for ranges a pivoted damper which opens to form the
boiler flue having pivots of unequal length and a slot to permit of the removal and
insertion of the damper in combination with a spur adapted to enter a notch in
the lower edge of the damper and prevent its displacement substantially as
described.
