I, WILLIAM FORD STANLEY, of Cumberlow, South Norwood, Surrey, do hereby
declare the nature of my said invention to be as follows :-
This Invention gives means of conducting heat to the interior parts of vessels used
for baking and boiling, such vessels to be used principally for cooking food upon
principles I have already patented, Specification No. 3990, 1886, of which this is an
extension.
For baking cakes, loaves, pies, tarts, and other food in tins, or metal dishes, I form
in the centre of the tin or dish a hollow cone preferably made of copper, which rises
with its base upon and from the lower surface. The hollow of the cone is left open
by perforating the tin or dish, to receive the heat radiated, from the hot plate, floor
of the oven, flame, or other heated surface used for baking. For baking loaves (open
or without tins) I make the same cone as described above with a flange only at its
base so as to insert in the bottom of the loaf. The metal cone may be either hollow
or solid and the flange may extend to the size of the loaf or beyond.
For boiling water making soup, or stewing I form a similar inetal cone to that
first described in the bottom of a pot, sauce pan, or kettle, but I bring the bottom
edge of the hollow cone to project about half an inch through and beyond the lower
surface of the pot. This bottom edge of the cone may be left plain or be fringed
outwards, and inwards, so as to attain greater heating surface, or it may be attached
or spread out into a plate similar in manner to that described in my former specifi-
cation for heat conductors mentioned above. The cones here described may be
varied in form or be in the form of blades. They will be made preferably of copper
and be tinned inside the vessel or part that comes in contact with the food, or liquid,
but they may be made of any other good conducting metal or alloy.

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 gives means of conducting heat to the interior parts of vessels used
for baking, and boiling, such vessels to be used principally for cooking food upon
principles I have already patented, Specification. No. 3990, 1886 of which this is an
extension.
For baking cakes, loaves, pies, tarts, and other food in tins, or metal dishes, I form
in the centre of the tin, or dish a hollow cone preferably made of copper which rises
with its base upon, and from the lower surface. The hollow interior of the cone is
left open by perforating the tin, or dish, to receive the heat radiated, from the hot
plate, floor of the oven flame, or other heated surface used for baking. For baking
loaves (open or without tins) I make the same cone as described above with a flange
only at its base so as to insert in the bottom of the loaf. In this case the metal cone
may be either hollow or solid and the flange may extend to the size of loaf, or
beyond.
For boiling water, making soup, or stewing I form a similar metal hollow cone to
that first described in the bottom of a pot, saucepan, or kettle, preferably I bring the
bottom edge of the hollow cone to project about half an inch through, and beyond
the lower surface of the pot. This bottom edge of the cone may be left plain or be
fringed outwards, and inwards, so as to attain greater heating surface, or it may be
attached or spread out into a plate similar in manner to that described in my former
specification for heat conductors mentioned above. The cones here described may be
varied in form, the apexes may be closed or open so that the form inscribes a conical
area, or they may be in the form of solid blades. They will be made preferably of
copper and be tinned inside the vessel, or part that comes in contact with the food,
or liquid, but they may be made of any other good conducting metal, or alloy.
The drawing will particularly indicate construction of the vessels according to this
invention. In all figures the cone, or inscribed conic area is shown in section at A
and in plan at A¹.

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
For the manufacture and use of an open cone or a form which encloses a conic
space placed in the bottom of a vessel to be used for baking, or boiling substantially
as described and illustrated by the accompanying drawings.
