Year: 1875

page_text: LETTERS PATENT to Frederick Goddard and Edward Massey, Engineers
and Ironfounders, both of the Town and County of the Town of
Nottingham, for the Invention of "IMPROVEMENTS IN HOT AIR HEATING
APPARATUS
"
Scaled the 15th Juno 1875, and dated the 14th April.1875.
PROVISIONAL SPECIFICATION left by the said Frederick Goddard and
Edward Massey at the Office of the Commissioners of Patents, with
their Petition, on the 14th April 1875.
We, FREDERICK GODDARD and EDWARD MASSEY, Engineers and Iron-
founders, both of the Town and County of the Town of Nottingham, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
HOT AIR HEATING APPARATUS," to be as follows.—
We employ an iron receptacle for fuel, which is provided on the outside
with projecting flanges. Portion of the interior is lined with firc-clay.
Fire and ash pit doors are hinged to the receptacle, which has an exit
pipe flanged on the outside to connect it to one end of a series of pipes
which are arranged to pass to and fro, and are connected to one or more

page_text: other series of pipes
Each pipe has projecting flanges on the outside
the outer end of the last series passing into the flue or chimney.
Each pipe is provided with a door, that can be readily opened to
admit a brush or scraper to clear out the soot when necessary. The
whole apparatus is enclosed in a plain or ornamental casing, which
opens into the heating flue or flues, or apartment requiring to be heated.
Wo sometimes employ gas instead of fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Goddard and Edward Massey in the
Great Seal Patent Office on the 13th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, FREDERICK
GODDARD and EDWARD MASSEY, Engineers and Ironfounders, both of
the Town and County of the Town of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of April, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Frederick Goddard and
Edward Massey, Her special licence that we, the said Frederick Goddard
and Edward Massey, our executors, administrators, and assigns, or such
others as wc, the said Frederick Goddard and Edward Massey, our
executors, administrators, and assigns, should at any time agree with,
and no othicis, from time to time and at all times thereafter during
the term therein expressed, should and lawfully mught make, usc,
excrcise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN HOT AIR HEATING APPARATUS," upon the condition (amongst
others) that we, the said Frederick Goddard and Edward Massey, 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 be filed in the
Great Seal Patent Office within six calendar months next and immc-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Frederick Goddard and Edward

page_text: The second modification is shewn partly in plan at Figure 4, the fire-
chamber being shewn in section surrounded by a jacket H, which is filled
with water through an inlet pipe I, one or more outlet pipes being fixed
at the top of the water jacket passing to the apartments requiring to be
heated. By such second modification of apparatus we are enabled to
supply dry hot air to one or more apartments and at the same time to
heat a greenhouse, conservatory, or other apartment or apartments by
means of hot water with one fire instead of two fires and separate
apparatus.
The third modification shewn in plan at Figure 5 is the same in con-
struction as the first or second modifications, but instead of employing
fuel to supply the requisito heat we-employ one or more rings J of gas
jets for burning either gas alone or gas and air Such ring or rings we
place within the flanged fuel receptacle B.
Having thus fully described the nature of our said Invention and the
manner of performing the same, wo wish it understood that we claim
the general arrangements and combinations of heating apparatus, as
lierein-before described and illustrated in the Drawings annexed.
In witness whereof, wc, the said Frederick Goddard and Edward
Massey, have hereunto set our hands and scals, this Twelfth a
day of October, in the year of our Lord One thousand eight
hundred and seventy-five.
Witness,
I. W. GOUGH, CE,
Nottingham.
