COMPLETE SPECIFICATION.
Improvements in and relating to Ovens.
I WILLIAM Ross LANE, Secretary to Smith and Wellstood Limited,
Ironfounders Bonnybridge, Stirlingshire, do hereby declare the nature of my
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement in writing that is
to say :-
This invention has reference to improvements in and relating to the ovens of
cooking stoves, ranges, and like cooking, baking, or heating apparatus, and has for
its object to give improved facilities for cleaning the soot out of the horizontal flue
beneath bottom of oven.
This is effected according to my improvements by casting, forming or fitting a
vertical web on the under surface of the oven bottom or panel, which is portable so
as to divide or partition the hollow space beneath bottom of oven into two flues or
channels when the oven is at work, but when the panel is removed the partition
web goes with it, and free access can thus be obtained to remove the accumulated
soot in bottom chamber.
And in order that my said invention and the manner of carrying same into
practice may be properly understood I have hereunto appended an explanatory
sheet of drawings in which
Figure 1 represents a diagram front view in perspective of an oven to which my
improvements have been applied.
Figure 2 is a detached plan view of the portable central bottom or panel of oven
with the dividing web cast on its under surface.
Figure 3 is a corresponding side elevation and
Figure 4 is an elevation at right angles to Figure 3.
Referring to these drawings:-
The web a¹ is cast on the central movable bottom or panel a, or rivetted, screwed
or otherwise affixed to it. When this panel a is fitted into place as shown in
Figure 1, the web a acts as a baffle plate or flue divider so as to direct the circuit
of heating gases from the inlet flue round the passes b, b', 62, to exit flue as
indicated by the arrows. The web a¹ may extend the full length of movable
panel a, or it may be a few inches shorter than panel, or as shown in the drawings
extend a few inches beyond panel at end opposite to cross passage of oven
bottom flue. If desired the panel a may be extended to front of oven and be
formed with an underhung flange a 2, so that when this panel or oven bottom is
removed, a clear space is left for cleaning purposes, thus forming a combined
movable oven bottom, flue divider, and cleaning outlet and dispensing with the
usual cleaning door.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
In ovens the forming or fitting of a vertical web or baffle plate on the under
surface of movable bottom panel, so as to act as a flue divider when fitted to oven,

page_text: and when the panel is removed provide free access for cleaning purposes, substantially
as herein described in reference to and shown in the accompanying drawings.
