IMPROVEMENTS IN GAS COOKING APPARATUS, AND IN STEAMING, BAKING, BOILING, AND ROASTING APPARATUS
Year: 1867

page_text: LETTERS PATENT to William Hill and Henry Charles Wilberforce, both
of the City of York, for the Invention of "IMPROVEMENTS IN GAS COOKING
APPARATUS, AND IN STEAMING, BAKING, BOILING, AND ROASTING APPARATUS."
Sealed the 13th August 1867, and dated the 18th February 1867.
PROVISIONAL SPECIFICATION left by the said William Hill and Henry
Charles Wilberforce at the Office of the Commissioners of Patents, with
their Petition, on the 18th February 1867.
We, WILLIAM HILL and HENRY CHARLES WILBERFORCE, both of the City of
York, do hereby declare the nature of the said Invention for "IMPROVEMENIB
IN GAS COOKING APPARATUS, AND IN STRAMING, BAKING, BOILING, AND ROASTING
APPARATUS" to be as follows:-
This Invention relates to certain improvements in apparatus for cooking,
including baking, roasting, steaming, and boiling.
We propose to arrange a furnace or fire-place with a retort, hydraulic
apparatus, condenser, and purifier, from which the gas to be employed in
cooking is caused to flow to the perforated bars whether for roasting, boiling,
or other operations. The spit is turned by means of clockwork springs
wound up by a handle, or in other instances a weight may be the motive
power. A basting spoon or ladle is fixed on an endless chain (after the
023

page_text: manner of a dredging machine) which tilts the gravy over the meat during its
revolution caused by the clockwork movement.
The steamer or boiler may be heated by means of a duplicate pipe or tube
inserted in a fire, the pipe being filled with water disseminates steam or
boiling water into the cooking apparatus.
The chimney is cleaned by means of a circular brush suspended by an
endless chain and pulley, and the brush being drawn upwards and downwards
thoroughly cleans the chimney from soot.
The roasting apparatus is arranged in front of the fire, and the various
pans for steaming or boiling are placed on the hot plate heated by gas or fuel.
The arrangements of the stove are nearly the same as those in ordinary use
for cooking by gas or other means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Hill and Henry Charles Wilberforce in the Great
Seal Patent Office on the 17th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
HILL and HENRY CHARLES WILBERFORCE, both of the City of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said William Hill and Henry Charles Wilberforce, Her special licence
that we, the said William Hill and Henry Charles Wilberforce, our executors,
administrators, and assigns, or such others as we, the said William Hill and
Henry Charles Wilberforce, executors, administrators, and assigns, should
at any time agree with, and no others, from time to time, and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
"IMPROVE.
Ireland, the Channel Islands, and Isle of Man, an Invention for
MENTS IN GAS COOKING APPARATUS AND IN STEAMING, BAKING, BOILING, AND
ROASTING APPARATUS," upon the condition (amongst others) that we, the said
William Hill and Henry Charles Wilberforce, our executors or administrators,
by an instrument in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to

page_text: be filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE. that we, the said William Hill and Henry Charles
Wilberforce, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This Invention relates to certain improvements in apparatus for gas making
and cooking, including baking, roasting, steaming, and boiling.
We propose to arrange a furnace or fire-place with a retort, hydraulic
apparatus, condenser, and purifier from which the gas to be employed in
cooking is caused to flow to the perforated bars, whether for roasting, boiling,
or other operations.. The spit is turned by means of clockwork springs wound
A
up by a handle, or in other instances a weight may be the motive power.
basting spoon or ladle is fixed on an endless chain (after the manner of a
dredging machine) which tilts the gravy over the meat during its revolution
caused by the clockwork movement.
The steamer or boiler may be heated by means of a pipe inserted in a fire,
the pipe being filled with water circulates steam or boiling water into the
cooking apparatus.
↑
The chimney is cleaned by means of a circular brush suspended by, an
endless chain and pulley, and the brush being drawn upwards and downwards
thoroughly cleans the chimney from soot.
The roasting apparatus is arranged in front of the fire, and the various
pans for steaming or boiling are placed on and within the hot plate heated by
gas or fuel. The arrangements of the stove are nearly the same as those in
ordinary use for cooking by gas or other means.
The annexed Drawings will render our Invention completely understood to
those conversant with apparatus for the purposes described.
Fig. 1 shews an elevation of steamers and gas-making apparatus; Fig. 2, a
front elevation of stove, sconce, steamer, and plate rack; Fig. 3, a section of
sconce with self-acting jack and chimney cleaner.
a is the clockwork or weighted movement working the roasting gear 6 by
bevelled wheels, and also the endless chain and basters c by the wheel d on
the shaft turned by the clockwork; e is the pulley on which the endless
chain works in order to clean the chimney by the circular brush; g is the
sconce, and the heating pipe; this pipe is so constructed that while only
one pipe goes into the fire for each section it has an ebb and flow pipe for
each section; the pipe h enters the fire between the bars and constitutes the
ebb pipe; the pipe i branches into the pipe h clear of and outside. the range

page_text: bars, as shewn, and constitutes the flow pipe; this arrangement of pipe, as
applicable to the steamers, is an essential feature in our general improve-
.ments. The fire-bars, fire, chimney, and other parts are shewn in section,
and require no special description. Fig. 4 represents a plan view of the
coppers, gas-making apparatus, sconce steamer, and side steamer, also the
gasometer; this view corresponds with Figs. 1 and 2, and shews the hydraulic
condenser and purifier combined, with the necessary pipes, connections, and
vessels k, k, the gasometer 1, the coppers m, m, the sconce steamer n, the
pipes o, o, o, for each section of the steamer, and for the side steamer n¹, the
openings o shewing the junction of the branch or flow pipe, as before
described, clear of the fire-bars; Fig. 5 is an elevation of the side steamer n¹.
The application of the gas will easily be understood by the application of
perforated bars of various forms, whereby the various operations in connection
with cooking.
In the Drawings saucepans are shewn closely fitting on the lids of the
sconces to hold stock, gravies, sauces, &c. The entire apparatus is made of
light materials, the form of the sconce steamer being semicircular, convex out-
wardly, and concave on the side nearest the fire; it is about 3 feet long,
1 foot 2 inches broad, and 18 inches in depth, the steamers themselves
being 9 inches deep, and the whole apparatus can be adjusted to the height
of the fire by means of screw legs. The lower part serves as a useful plate rack
to keep plates hot for immediate use, while the whole steamer effectually screens
the fire from the cook, and prevents its radiation into the kitchen. The two
taps observable in front of the lower part of the steamer are for the purpose
of drawing off the water after the apparatus has been used. The dotted line
shows the perforated bottom of the steamer, acting also in the capacity of a
fish plate when required; upon this false bottom descend three partitions,
making four separate divisions of the steamer, in which can be cooked as
many different kinds of joints, fowls, fish, or vegetables.
Having now described the nature of our Invention, and the manner in
which the same is to be carried into effect, we would remark that we do not
restrict or limit ourselves to the precise details and configuration of parts
which we have expressed and shewn, as the same may obviously be varied or
modified without in any degree departing from the principles on which our Inven-
tion is based; but what we claim and desire to he secured to us by the herein
in part recited Letters Patent are, the general arrangement and combination
of parts or apparatus constituting a gas cooking apparatus applicable to all
purposes to which cooking may be required, or to roasting, boiling, or heating
or steaming; and also the apparatus for steaming, baking, boiling, and

page_text: roasting, substantially as herein specified and illustrated by the Drawings
annexed.
In witness whereof, we, the said William Hill and Henry Charles
Wilberforce, have hereunto set our hands and seals, this Fourteenth
day of August, in the year of our Lord One thousand eight hundred
and sixty-seven.
