PROVISIONAL SPECIFICATION.
Improvements in and relating to Electrical Hot Plates.
We, THOMAS FLETCHER of Thynne Street, Warrington in the County of
Lancaster, Manufacturer of Gas Apparatus, WILLIAM RUSSELL of Scotia
Foundry, Pendleton, in the County of Lancaster, Iron Founder, and FLETCHER
RUSSELL & Co. LIMITED, of Thynne Street, Warrington in the County of
Lancaster, Manufacturers of Gas Apparatus and Iron Founders, do hereby declare
the nature of this invention to be as follows:-
This invention relates to plates which are heated by electricity and are used for
cooking and heating purposes, and its objects are to obtain a greater effective heat
radiating surface and to provide simple and efficient means for effecting the
immediate drainage from the plates of any liquids, juices, melted fats or the like
which may fall thereon.
A plate constructed according to this invention is cast or otherwise formed with
suitable holes or perforations which may be of any desired or convenient shape and
may be arranged to form a pattern upon the plate. The electrical conductors are
arranged about around or between the holes or perforations upon the solid parts of
the plates. The solid parts of the plate are slightly convex or conical in cross
section or are otherwise formed to slope downwards towards the perforations so
that any juice, liquid, or the like, falling upon a solid part of the plate immediately
runs down towards and is discharged through one or other of the perforations.
Gutters, or a suitable receptacle, are preferably arranged beneath the perforations.
The convex or other form of the solid parts of the plate provides such parts with
a greater effective heat radiating surface than would be the case if they were flat.
Any usual method of arranging the electrical conductors upon the plate and of
connecting them together or to the leads, may be adopted.

Improvements in and relating to Electrical Hot Plates.

Lancaster, Manufacturer of Gas Apparatus, WILLIAM RUSSELL of Scotia
Foundry, Pendleton, in the County of Lancaster, Iron Founder, and FLETCHER
RUSSELL & Co. LIMITED of Thynne Street Warrington in the County of

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 relates to plates which are heated by electricity and are used for

page_text: A plate constructed according to this invention is cast or otherwise formed with
suitable holes or perforations which may be of any desired or convenient shape and
may be arranged to form a pattern upon the plate. The electrical conductors are
arranged about, around, or between, the holes or perforations upon the solid parts
of the plate. The solid parts of the plate are slightly convex or conical in cross
section or are otherwise formed to slope downwards towards the perforations, so
that any juice liquid or the like falling upon a solid part of the plate immediately
runs down towards and is discharged through one or other of the perforations.
Gutters or a suitable receptacle are preferably arranged beneath the perforations.
Owing to the convex or other form of the solid parts of the plate between or
around the perforations, these parts have a greater effective heat radiating surface
than they would have if they were flat.
The accompanying drawings to which we refer hereinafter, illustrate types of
electrical hot plate constructed to embody our improvements; similar letters of
reference being used to indicate similar parts in the figures.
Figure 1 illustrates in plan, part in section, one form of our improved hot plate.
Figure 2 similarly illustrates another form.'"
Figure 3 shews in section part of another form of plate.
In each figure, A is the hot plate having the holes or perforations B formed
through it, preferably by casting. It is evident that the shape of the holes and
their disposition may be varied to any required extent and they may be so
arranged as to form any desired pattern. The solid parts C of the plate between
and around the holes B are slightly convex or conical or are otherwise suitably
formed to conduct any liquids or the like falling upon them to the holes, through
which they pass and are discharged into gutters or a receptacle.
It is preferred to form the holes B with sides having a considerable slope and
sharp lower edges so as to facilitate the discharge or dripping of any liquids or
juices conducted to them.
Any usual method of arranging the electrical conductors upon the plate and of
connecting them to the leads may be adopted.
Having now particularly described and ascertained the nature of our said inveu-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. An electrical hot plate provided with holes or perforations and with solid
parts which slope towards the holes or perforations, substantially as and for the
purpose herein before set forth and as illustrated by the accompanying drawings.
2. An electrical hot plate constructed substantially as and for the purpose
.herein before set forth and as illustrated by the accompanying drawings.
