Complete Specification Left, 14th Dec., 1898-Accepted, 18th Mar., 1899
I, JAMES KINMOND SMITHI, of 294, Leith Walk, in the County of the City of
Edinburgh, North Britain, Baker and Confectioner, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in hot plates for firing scones, cakes,
and such like, and has for its object, not only to economise fuel, but to so con-
struct them in such a manner as to be able to regulate the heat at will.
In carrying out my invention I make the internal roof of the furnace flat or
slightly dome-shaped and with a flue or passage running on each side thereof
with openings at suitable distances apart through which the flames from the
furnace pass to the hot plate. Dampers are provided so that any of these open-
ings can be closed or opened as may be found desirable in order to regulate the
heat and throw it back or bring it forward as required. These dampers may be
in the form of a brick so that when they are closed they become as it were wedged
into the openings, or they may be ordinary sliding or hinged plates or any
other form as may be found most convenient The hot plate rests on two plates
filled in with asbestos or it may rest on a brick or other wall or support.

Improvements in Hot Plates.
I, JAMES KINMOND SMITH, of 294, Leith Walk, in the County of the City of
Edinburgh, North Britain, Baker and Confectioner, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:―
This invention relates to improvements in hot plates for firing scones, cakes,
and such like, and has for its object, not only to economise fuel, but to con-
struct them in such a manner as to be able to regulate the heat at will.
In order that my invention may be properly understood I will now describe
my invention reference being made to the accompanying drawings of which,
Figure 1 is a front elevation of a hot plate and its furnace shewing my
improvements.

page_text: Figure 3 is half section through the line A, B, and half section through the
line. C, D, both of Figure 2.
Figure 4 is a side elevation.
In carrying out my invention I make the internal roof A of the furnace B,
flat or slightly dome-shaped and with flues or passages C running on each side
thereof (one side only being shewn in the drawings) through which the flames
from the furnace pass to the hot plate E. Dampers D which may be in the form
of a brick or other convenient form are provided so that any of these openings C
which communicate from the furnace A to the hot-plate chamber E¹ can be
closed or opened or partially so as may be found desirable in order to regulate
the heat and throw it back or bring it forward as required. Dampers E. which
may be in the form of hinged doors as shewn in Figure 4 or ordinary sliding
doors are provided in order to regulate the supply of cold air to chamber E¹.
The hot plate E rests on two plates filled in with asbestos or silicate cotton, or
it may rest on a brick or other wall or support.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
! :
In hot plates, constructing these in such a manner as not only to economise
fuel, but to be able to regulate the heat at will substantially as herein before
described and illustrated on the accompanying sheets of drawings.
