IMPROVEMENTS IN KITCHEN RANGES
Year: 1884

page_text: I ALEXANDER WALKER, of the firm of Walker, Turnbull and Company, of Port
Downie Iron Works, Falkirk, in the County of Stirling, Iron Founder, do hereby
declare the nature of my said Invention for " IMPROVEMENTS IN KITCHEN
RANGES," to be as follows:-
This Invention relates to improvements in the construction and mode of fitting
the front grate bars or grating and falling top bar of fire ranges or kitcheners.
The improved grate bars are formed of cast-iron in one piece, and instead of
being rigidly secured, as usual, to the body of the range on each side of the fire
place, they are fitted to slide in vertical grooves or guides formed in cheek plates
which are bolted or screwed to the range. The falling top bar is made of a
separate casting formed with a projecting pin on each side or end which fits in the
grooves at or nearly at a level with the top cross bar of the grating, which is cut
away at each side, to admit the lower end of the sides of the falling bar when it is
raised. Each side piece of the falling bar extends down beyond the pivot or pin
on which the bar swivels, and is formed with a catch which by bearing against the
upper part of the grating retains the falling bar in its vertical position up against
projections on the back guides. When the falling bar is to be lowered to its
horizontal position, it is first slightly raised to free its catch pieces from the
retaining upper edge of the grating, and then canted forward, the under side of the
catch pieces being rounded so that they glide freely over the retaining edge, and
allow the falling bar to drop. The falling bar is sustained in the horizontal
position by projecting ribs formed on each cheek plate, one pair in front on which
the falling bar rests, and the other pair behind against which bear the upper sides
of the lower ends or catch pieces of the falling bar. An enlargement or projection
is formed on the inner side of each end of the falling bar, to prevent its
displacement or removal unless when the entire front grating is raised to the top
of the grooves in the cheek plates.

I ALEXANDER WALKER, of the firm of Walker, Turnbull and Company of Port
Downie Iron Works, Falkirk in the County of Stirling, Iron Founder, do hereby
declare the nature of my said Invention for "IMPROVEMENTS IN KITCHEN RANGES,"
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 improvements in the construction and mode of fitting
the front grate bars or grating and falling top bar of fire ranges or Kitcheners, aud
it is illustrated by the accompanying drawings in which figures 1, 2 and 3 are
respectively a front elevation, side elevation, and sectional plan of a modification of
the improved grating and fall bar. Figures 4, 5. and 6 are similar views of another
modification.
The improved grate bars A are formed of cast iron in one piece and instead of
being rigidly secured as usual to the body of the range on each side of the
fire-place, they are fitted to slide in vertical grooves or guides b formed in cheek
plates B which are bolted or screwed to the range by the snugs b¹. The falling
top bar C is made of a separate casting formed with a projecting pin c on each side
or end which fits in the grooves at or nearly at a level with the top cross bar of
the grating which is cut away at each side to admit the lower end c¹ of the sides
of the falling bar C when it is raised. Each side piece of the falling bar C extends
down beyond the pivot or pin c on which the bar swivels, and it may be formed
with a catch c which by bearing against the upper part of the grating will retain
the falling bar C in its vertical position up against projections 6' on the back
guides as in figure 4. Or, as is preferred the catch pieces c² are formed at the
upper edges of the falling bar C to fit within the groove b and thereby retain the
bar as in figure 1. When the falling bar C is to be lowered to its horizontal
position as in figures 2 and 5 it is first slightly raised to free its catch pieces c³
from the retaining upper edges B₁ of the cheek plates B or from the upper part of
the grating as the case may be, and then canted forward, the under side of the
catch pieces c² being in each case rounded so that they glide freely over the
retaining edge and allow the falling bar to drop. The falling bar is sustained in
the horizontal position by the projecting ribs 6, 6s formed on each cheek plate B,
one pair b³ in front on which the falling bar C rests, and the other pair b³ behind
against which bear the upper sides of the lower ends or catch pieces c¹ of the
falling bar. An enlargement or projection c¹ is formed on the inner side of each
end of the falling bar to prevent its displacement or removal from the grating A
unless when the entire front grating is raised to the top of the grooves in the cheek
plate B.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is,
First. The combination of parts forming the improved grating and falling bar
for kitchen ranges, substantially as described and illustrated.
Second. The improved falling top bar for kitchen ranges arranged to operate
substantially as described and illustrated.
Dated this Second day of October 1884.
ALEXANDER WALKER.
