We, ROBERT HUNTER, Ironfounder, and JOHN TURNBULL, Foreman Patternmaker,
both of Port Downie Iron Works, Falkirk, in the County of Stirling, do hereby
declare the nature of this invention to be as follows:-
Our invention which relates to kitchen ranges consists in providing in connection
with the fire-grate a movable bottom with improved devices for vertically raising or
lowering and sustaining the same whereby the depth of the burning fuel in the grate
may be suitably regulated, a shallow fire being maintained in proximity to cooking
utensils placed over it on the level of the hob by raising the movable bottom, and a
deep fire adapted for roasting or cooking in front of the grate being obtained by
lowering the bottom and filling up the grate with fuel.
In carrying out our invention we form or secure on a movable grating which forms
the bottom of the fire-grate of the range, a toothed or serrated rack projecting vertically
downwards from the under side of the grating, and in gear with this rack which is
retained in place by suitable guides we fit a pinion upon a spindle extending hori-
zontally from the front towards the back part of the range where it passes through a
slot in a bracket piece, and provided in front with a square end and a crank handle or
other suitable means whereby the spindle and pinion may be turned to actuate the
rack and movable bottom. On one or both ends of the spindle but preferably on the
rear end we form a square or polygonal head which rests upon a rib formed on
the bracket piece and when the movable bottom has been brought to the desired
position by turning the spindle the flat side of the polygonal head prevents the
turning back of the spindle by the rack.

page_text: Improvements in Kitchen Ranges.
We, ROBERT HUNTER, Ironfounder, and JOHN TURNBULL, Foreman Patternmaker,
both of Port Downie Iron Works, Falkirk in the County of Stirling, 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 which relates to kitchen ranges consists in providing in connection
with the fire grate a movable bottom with improved devices for vertically raising or
lowering and sustaining the same whereby the depth of the burning fuel in the grate
may be suitably regulated, a shallow fire being maintained in proximity to cooking
utensils placed over it on the level of the hob by raising the movable bottom, and a
deep fire adapted for roasting or cooking in front of the grate being obtained by
lowering the bottom and filling up the grate with fuel.
As represented by the annexed drawings in which figure 1, is an elevation (part of
the front plate being removed) and figure 2, a cross section of a kitchen range
illustrating our invention, we form or secure on a movable grating A, which forms
the bottom of the fire grate B of the range a toothed or serrated rack C, projecting
vertically downwards from the under side of the grating A; and in with this
gear
rack, which is retained in place by suitable guides D, at the lower side of the fire
grate, we fix a pinion E, upon a spindle F, extending horizontally from the front
towards the back part of the range where it passes through a slot 9, in a bracket
piece G, the spindle being provided in front with a square end f to which may he
fitted a crank handle or other suitable device whereby the spindle and pinion may be
turned to actuate the rack and movable bottom. On one or both ends of the spindle
but preferably on the rear end we form a square or polygonal head H, which rests
upon a rib I formed on the bracket piece G, and when the movable bottom has been
brought to the desired position by turning the spindle F, the flat side of the polygonal
head H, by resting on the rib I, prevents the turning back of the spindle by
the rack.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. In a kitchen range having a movable bottom grating the combination of devices
for effecting the raising and lowering and sustaining of said movable grating sub-
stantially as described with reference to the drawings annexed.
2. In conjunction with the movable bottom grating of a fire range operated by a
rack and pinion the polygonal head H upon the actuating spindle adapted to provide
a rest or stop to sustain the grating in its raised position substantially as herein
described.
