page_text: utterly cease, determine, and become void, as in and by the same, relation
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Slater, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained by the Drawing hereunto annexed, and following description
thereof (that is to say):-
The nature of my Invention and improvements in making a kitchen range
and apparatus for cooking and other purposes consists in making an apparatus
with wrought or cast iron bars, and cast iron sides, with a moveable keeper
and spit racks in front for roasting. At the back or behind I fix what I call a
hot water boiler, forming in the front part an open fire-place of a large or small
size, and to be made with or without the keeper and spit racks, as may be most
convenient. The hot water boiler is situated at the back of the fire place, and
is made of wrought or cast iron and copper tinned, but to be made with or
without copper, as most convenient. In front there is a hole or opening of a
proper size for a chimney flue into the inside of the hot water boiler, and to the
hole or opening is fixed, with bolts and screws or rivets and inside pipe aud
flange or chimney flue, which pipe or flue is continued up the inside to the top
of the hot water boiler, and over it is a lid or cover for admitting a free passage
of fire or heat through the hot water boiler, or to exclude it therefrom, as it
may be required; and in one side or end of the hot water boiler a man-hole or
opening is made of six inches diameter, or of a larger or smaller size, as most
convenient, and round the man-hole or opening there is a projecting ring or a
bearing formed, of one inch thick and two inches broad, but to be made thicker
or thinner, broader or narrower, as most convenient, for keeping and main-
taining at a proper and convenient distance the hot water boiler from what I
call a steam and water reservoir, and for bolting and screwing or joining
together at and all round the man-hole or opening of the hot water boiler with
the steam and water reservoir, and for making or forming an open commu-
nication with both of them, and other purposes; and at the end or side near to
the top of the hot water boiler are two holes or pipes projecting inside for the
purposes of receiving steam pipes of two inches diameter, or of a smaller or
larger size, as most convenient. One of the pipes with a valve or stopper is
for taking off and regulating the waste steam; the other pipe with a cock or
stopper being for conveying the steam from the hot water boiler to heat a
vapour or a hot water bath, and for warming hot dressers, hot closets; rooms,
and apartments, and for other purposes and conveniences; and the hot water

page_text: boiler is to be fitted up for other purposes and conveniences, with one hole or
pipe at the top projecting inside for the purpose of receiving into it an upright:
waste steam pipe with a valve or stopper; and in the bottom of the hot water
boiler is fixed with screws or rivets an upright inside steam pipe with an hori-
zontal or square elbow turn at the bottom, which elbow is to be united or
joined together with a short pipe and cock for the purpose of conveying or
bringing down the steam. through the pipe inside the hot water boiler into
what I call a steam receiver and condenser.; and which steam receiver or con-
denser is.fixed underneath the. steam and water, reservoir, and is made either.
of cast or wrought iron or other metal in the form of an L square case, without
a lid or cover, and in the inside is made or fixed a box complete, of a smaller
size than the outward case. The outward case is to receive cold water, and
the inward box the steam from the inside of the hot water boiler, which is more
fully explained by the Drawing herewith; and at one side or end of the kitchen
rangé fire-place I fix with bolts, screws, or fastenings a separate fire-place with
a stew hearth and baking oven or roaster eighteen inches wide in front, the fire-
place and stew hearth corresponding in front with the size of the baking oven-
or roaster, but they are to be made larger or smaller, as most.convenient; and.
tivo or more sets of the fire-places, stew hearths, baking ovens, or roasters are
to be made and fixed to act with the kitchen range and apparatus if more con-
venient. The stew hearth and fire-place I make of cast iron or cast iron and:
fire' bricks; the top or upper part consists of an outward square frame, or of;
any other form or forms, as most convenient, having a sunk groove or bearing
inside to support and contain a flat plate or three flat plates inside, the middle.
or centre one having a hole or opening to admit or receive a round or other
formed lid or cover of nine inches diameter, or a larger or smaller size, as may
be most convenient, so as to form a flat surface over the stew hearth fire-
place; and the baking oven or roaster I make of wrought or cast iron with flues
or openings all round, and over the top is the chimney, with a valve or damper.
to regulate the fire. The bottom or under part of the baking oven or roaster
is made of cast iron, fire-brick, or stone, which I call 'a fire repeller and hot-air
flue, having as large an opening into the flue as the fire repeller will permit of.
The said opening or flue is twenty inches long inside, and is continued across
and under the baking oven or roaster, but to be made longer or shorter, as
most convenient; and at or near to the further end of the hot-air flue there are
made one or more small holes or openings into the inside of the baking oven or.
roaster, and in front of the same is a valve or stopper, which forms a covering
over the entrance-of the hot-air flue in the fire repeller, and is for the pur-

page_text: poses of admitting hot air into the baking oven or roaster, or to exclude it.
therefrom; and at the top.or upper part of the baking oven or roaster is fixed
what I call a hot-air escape pipe and valve, for the purpose of giving a discharge
to the hot air which has passed through the fire repeller, hot-air flue, and the
baking oven or roaster, or for keeping or retaining in the same. But to explain
more fully the baking oven or roaster, the baking oven acts for roasting at the
time the valves, pipes, and flues are open, and a free current of hot air is
permitted to enter and pass through them, and the reverse when the valves,
pipes, and flues are closed and prevented from acting, it then becomes a baking
oven; and the said baking oven or roaster is fixed into stands upon or against
the top or back part of the stew hearth, and is acted upon by the stew hearth
fire; and at the other side or at both the end and back parts of the kitchen
range fire-place I fix with bolts, screws, or fastenings what I call a steam and
water reservoir, which is made of copper tinned, or to be made of any other
metal or metals, as most convenient, of a square form, twelve inches deep,
eighteen inches broad in front, and twenty inches long, but to be made of any
other form or forms, deeper or shallower, broader or narrower, and longer or
shorter, as most convenient. The top or upper part is made with what I call a
top frame, which is divided into four separate compartments of a square or oval
form, but to be made with more or a less number of separate compartments,
and of any other form or forms, as is most convenient. The top frame with
the separate compartments, are for holding or containing cooking kettles,
which are made of tin, tin plates, copper tinned, cast or wrought iron tinned,
or without tinning, and of such size or sizes, form or forms as most convenient
to fit into the top frame compartments and the steam and water reservoir; all
or the whole of the kettles are made with holes, pipes, or apertures at or near
to the top or upper parts for the purpose of admitting steam into the inside for
cooking, their outsides at the time being surrounded with the steam in the
steam and water reservoir; and on or against the front of the steam and water
reservoir I fix with screws, rivets, or fastenings an outward lip or fountain, so
as to communicate with the inside of the steam and water reservoir, and which
lip or fountain is so fixed as to act as a guard against having over much water,
and for receiving and keeping a regular supply; and under or near to the lip
or fountain is fixed a cock for drawing off hot water, and in one side of the
steam and water reservoir a man-hole or opening is made, of a size correspond-
ing to the one in the hot water boiler, at which man-hole or opening both the
hot water boiler and the steam and water reservoir are joined together with
bolts, screws, and fastenings, and inside the steam and water reservoir a

page_text: descending pipe or flue is made or fixed for warming a hot closet underneath,
of an ordinary make, and under it a receiving pan is placed to collect con-
densed steam water, and to be made with or without the descending pipe and
hot closet, as most convenient. The Drawing herewith is made for better
elucidating and explaining the kitchen range, apparatus, and compartments.
In witness whereof, I, the said John Slater, have hereunto set my
hand and seal, this 22d day of January, in the year of our Lord
Inrolled the Twenty-sixth day of January, in the year of our Lord One
thousand eight hundred and twenty-two.
