Year: 1884

I JOSEPH WALKER of 119, Bradford Road, North, Huddersfield, Yorkshire,
Commission Agent do hereby declare the nature of my invention for "A NEW
OR IMPROVED "DRAW TIN OR APPLIANCE FOR FIXING ONTO FIRE-RANGES
to be as follows:-
"
"
This Invention has reference to a new or improved draw tin or plate for fixing
onto the bars of fire ranges, when the oven is required to be heated for baking,
cooking, or other purposes, and its object is to draw together or concentrate a
larger amount of heat and cause such heat to circulate on the underside of the
oven.
In order to carry out my Invention I construct a rectangular or other con-
veniently shaped plate of cast iron or other metal, with the side fronting the fire,
concave or dished, which (by preference) I so arrange that the centre of the concave
part is opposite the second bar or rib of the fire range; on the same side and at
the top of the said plate is formed a finger or projection, by which the plato is
suspended on the range.
When the oven is required to be heated, the plate is hung on the top bar and
near to the oven, and the smoke issuing from the fire is not allowed to go under
the oven, but is drawn into the concave dish and consumed.
At the back of the concave dish I form a handle for the purpose of lifting it
onto, or removing it from the range.
By the application of this plate to fire ranges, when the oven is required to be
beated, a great saving of coal is effected.
The above plate may be used with equal advantage when the boiler (which is on
the opposite side of the oven) is required to be heated.

I JOSEPH WALKER of 119 Bradford Road, North, Huddersfield Yorkshiro,
Commission Agent do hereby declare the nature of my invention for "A NEW
OR IMPROVED "DRAW TIN OR APPLIANCE FOR FIXING ONTO FIRE RANGES
and in what manner the samo is to bo performed, to be particularly described
and ascertained in and by the following statement :—
This invention has reference to a new or improved "draw tin" or plate for fixing
onto the bars of fire ranges when the oven is required to be heated for baking,
cooking or other purposes, and its object is to draw together or concentrate a
larger amount of heat, and cause such heat to circulate on the underside of the oven.
In order that my invention may be more easily comprehended, I herein give
reference to the accompanying sheet of Drawings illustrative thereof.
Fig 1. is front view of my improved plate, which may be constructed of cast iron
or other suitable metal.
At the back of this plate (see Fig 2 which is back view in perspective) I form a
concavo dish or recess A which is placed opposite the fire, and (by preference) so
arranged that when hung on the range, the centre of the concave dish is opposite
the second bar or rib. On the same side of the plate as the concave dish, and at
the top thereof I form a hook B by which the plate is suspended on the top bar
of the range.
When the oven is required to be heated, the plate is hung on the top bar and
near to the oven (see Fig 3 which shews the application of the plate to fire ranges)
and the smoke issuing from the fire is not allowed to go under the oven, but is
drawn into the concave dish and consumed.
At the back of the concave dish (see Fig 1) I form a handle C for the purpose
of lifting the plate onto or removing it from the range.
By the application of this plate to fire ranges when the oven is required to
be heated, a good fire is drawn up at that part opposite the plate, and the
smoke issuing therefrom is drawn into the concave dish and consumed, by which
means, a great saving of coal is effected, and also a saving of time, as the oven is
more quickly heated and the temperature thereof kept more regular, than when
the plate is not used.
The plate may also be used with equal advantage, when the boiler (which is on
the opposite side of the oven) is required to be heated.
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
In a "draw tin." or plate, the formation thereon of a concave dish or recess A,
employed in the manner and for purposes substantially as herein shewn and.
described.
