Improvements in Cooking and Heating Apparatus and Appliances.
I, WILLIAM CHARLES BUTLER, Restaurant Manager Grand Restaurant.
Edinburgh do hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved method of grilling. I construct
one two, three, or more separate chambers or compartments. Each chamber or
compartment is a separate and individual grill. The gridiron necessary and
requisite for the proper working of my invention consists of two oblong gridirons
smaller or larger as may be required hinged together by proper metal or other-
Each is
fastenings, and capable of being folded together in book like form.
provided with a handle so fixed that when folded up the handles overlap each
other. Into this gridiron which I shall here call the vertical gridiron the articles
to be grilled, cooked, or toasted are placed, and when so placed the vertical gridiron
is then placed vertically in the grill.
Each of the chambers or compartments before mentioned, and which forms the
subject of my invention, is constructed thus: -While it may be made of any size
or dimension I would preferably construct it of about eighteen inches in height
by about the same extent in depth from front to back. 1 divide it vertically
into three sections, an inner and two outer sections. The inner section is pro-
vided with rests or supports for the vertical gridiron and is of such width as
will contain the vertical gridiron and its contents, or it may be of such width as
will be otherwise requisite or necessary. Each of the two outer sections is
supplied with a gas heating apparatus running from the bottom to the top of
the section and from the front to the back thereof, or fixed or placed otherwise
and in such a manner that the whole outer surface of the inner section is played
upon by what is practically one flame of gas. In this manner the two walls of
the inner section can be speedily brought to any degree of heat that is necessary
or desirable. The gas heating apparatus which I would use for the above purpose,
would consist of a series of gas tubes, cut or slotted in such a manner, and
arranged in such a manner, as will give the desired extent of flame, and the whole
gas would be supplied through a Bunsen burner.
The whole grill apparatus would be made of cast or wrought iron, asbestos, or
other suitable material.
The advantage of the foregoing method of grilling is that both sides of the
article are cooked at one and the same time, and thereby a saving is effected in
time, labour, and fuel.
The grill hereinabove described, I propose to call "The Grand." It can be
used for or fitted to any existing gas cooking stove. It can be made or adjusted
to cook or deal with any number or quantity of articles.

COMPLETE SPECIFICATION.
Improvements in Cooking and Heating Apparatus and Appliances.
I, WILLIAM CHARLES BUTLER, Manager, Grand Restaurant, Edinburgh, do
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 :-
My invention relates to improvements in cooking and heating apparatus, and has

page_text: for its object to cook both sides of an article or articles at one and the same time-
whereby a considerable saving of time, labour, and fuel is effected.
In carrying my invention into practice I construct one, two, three, or more
separate chambers or compartments of any suitable metal or material, cach
chamber or compartment constituting a separate and individual grill, which I will
hereinafter more fully describe.
The gridiron requisite and necessary for the proper working of my invention
consists of two oblong gridirons, smaller or larger as may be required, hinged
together by proper metal or other fastenings and capable of being folded together
in book-like form. Each is provided with a handle so fixed that when folded up
the handles overlap each other. Into this gridiron, which I shall here call the
"vertical gridiron," the articles to be grilled, cooked, or toasted are placed, and
when so placed the vertical gridiron is then placed vertically in the grill.
Each chamber or compartment before mentioned is constructed in the following
manner. It may be made of any size or dimensions, but I prefer to construct it of
about eighteen inches in height by about the same extent in depth from front to
back. I divide it vertically into three sections. These sections are each provided
with guides or rests for the vertical gridiron, and are of such width as will contain
the vertical gridiron and its contents; or they may be of such width as may be
otherwise requisite or necessary. Each of these sections is supplied with a gas
heating apparatus running from the bottom to the top of the section and from the
front to the back thereof, or fixed or placed otherwise and in such a manner that
each section can be speedily brought to any degree of heat that may be necessary
or desirable.
In order that my invention may be properly understood and readily carried into
effect. I have hereunto appended three explanatory sheets of drawings in the
several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a front elevation showing my apparatus.
Figure 2 is a horizontal section of the same.
Figure 3 is a front elevation of the gridiron.
A, A, A are the three separate chambers or compartments, which may be made
of cast or wrought iron, or any other suitable metal or material, each of which
constitutes a grill. B are the rests or guides for the vertical gridiron, which are
riveted or otherwise secured to the inside of the top and bottom of each of the
chambers A, A, A. The heating apparatus consists of pipes D, which run from
the bottom up the sides and along the front of each of the chambers A, A, A, the
pipes in each chamber being connected with a Bunsen burner E, from which the
whole gas is supplied. The pipe leading from the Bunsen burner E to each
chamber A has a stop-cock F to regulate the supply of gas to the separate
chambers. To each chamber A there are two doors G, G, which are hinged to the
sides of each section. I also provide an opening in the top of each chamber A
having movable covers to allow the vapors to escape.
The vertical gridiron, as more fully illustrated in Figure 3 of the accompanying
drawings, consists of two oblong gridirons H, H', hinged together by pieces of
wire h, h, or other suitable fastening. These gridirons H, H' have each a
handle II, and to I there is a movable ring J, which when a steak, chop, or other
article or articles is or are to be cooked, is placed over I' to keep the two grid-
irons H H together, and thus prevent the article from falling out.
In cooking a steak, chop, or other article I open out the two gridirons H, H',
place the article or articles in between these, fold them together, and then place
the ring Jover I¹ to retain the article or articles in its or their place. I then pass
this vertical gridiron (as I have hereinbefore designated it) containing the article or
articles, down the guides or rests B into the chamber A, and turn on the gas, or
the gas may be turned on before this so as to have the chamber heated before the
article is placed therein. The vertical gridiron being in a vertical position and in

page_text: the centre of the chamber, both sides of the article are cooked at the same time,
thus saving time, labour and fuel.
The gravy which comes from the articles being cooked falls down into a
gravy-pan
K which is placed inside and at the bottom of each chamber A
through an opening or space L.
- The apparatus as hereinbefore described can be fitted to any existing gas cooking
stove and can be made so as to cook any number or quantity of articles.
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 1
claim is :-
1. The general arrangement, construction, and combination of the parts con-
stituting the cooking and heating apparatus substantially as and for the purposes.
hereinbefore described and illustrated on the accompanying sheets of drawings.
2. The vertical gridiron, constructed substantially as and for the purposes
herein before described and illustrated more particularly in Figure 3 of the accom-
panying sheets of drawings.
