Year: 1871

page_text: LETTERS PATENT to Joseph Wilde, of Guide Bridge, near Manchester,
in the County of Lancaster, Builder, for the Invention of "IM-
PROVEMENTS IN HEATING APPARATUS FOR STOVING OR ' PROOFING'
HATS, AND FOR OTHER PURPOSES."
FELT
Sealed the 21st June 1872, and dated the 29th December 1871.
PROVISIONAL SPECIFICATION left by the said Joseph Wilde at the
Office of the Commissioners of Patents, with his Petition, on the
29th December 1871.
I, JOSEPH WILDE, of Guide Bridge, near Manchester, in the County
3 of Lancaster, Builder, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN HEATING APPARATUS FOR STOVING OR 'PROOFING' FELT
HATS, AND FOR OTHER PURPOSES," to be as follows:-
:―
In stoving or proofing felt hats a constant and uniform temperature
is required in the chamber in which the operation is carried on of about
180 degrees Fah. This has not been accomplished in a satisfactory
manner hitherto, or if so it has been by expensive apparatus wasteful
of fuel.

page_text: My Invention refers to a simple and inexpensive apparatus, which
accomplishes the object required in a perfect and satisfactory manner
with a small expenditure of fuel, and requiring little attention to keep
the temperature uniform or nearly so.
My Invention consists in a chamber or box, in which grate bars for
the furnace are placed; it is provided with a fire-door and ash-pit, that
may, if required, be closed to the chamber, but it is arranged to com-
municate by a pipe or channel with the atmosphere at the outside of
the chamber. The said fire chamber or box has a series of pipes, vertical
or otherwise, their lower ends being connected with its upper surface,
and their upper ends with a chamber or box that has communication
with the outlet chimney or flue. The products of combustion pass from
the fire-box up the said tubes and into the smoke-box or upper chamber,
and then into the flue leading to the chimney. The upper box is made
with a cover that can be removed to get access to the tubes, which are
provided, if required, with covers or dampers to regulate the draught.
through them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Wilde in the Great Seal Patent Office
on the 28th June 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WILDE, of Guide Bridge, near Manchester, in the County of Lancaster,
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of December, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Wilde, Her special license that
I, the said Joseph Wilde, my executors, administrators, and assigns,
or such others as I, the said Joseph Wilde, my executors, adminis-
trators, 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 Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN HEATING

page_text: '
APPARATUS FOR STOVING OR PROOFING FELT HATS, AND FOR OTHER PURPOSES,"
upon the condition (amongst others) that I, the said Joseph Wilde,
my executors or administrators, by an instrument in writing under my,
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 immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Wilde, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings (that is to
say) :-
In stoving or proofing felt hats a constant and uniform temperature
is required in the chamber in which the operation is carried on of about
180 degrees Fahrenheit. This has not been accomplished in a satis-
factory manner hitherto, or if so, it has been by expensive apparatus
requiring much attention and wasteful of fuel.
My Invention refers to a simple and inexpensive apparatus, which
accomplishes the object required in a perfect and satisfactory manner
with a small expenditure of fuel, and requiring but little attention to
keep the temperature uniform or nearly so. :
My Invention consists in a chamber or box, in which grate bars for
the furnace are placed; it is provided with a fire-door and ash-pit, that
may, if required, be closed to the chamber, but it is arranged to com-
municate by a pipe, channel, or flue with the atmosphere at the outside
of the chamber. The said fire chamber or box has a series of pipes,
vertical or otherwise, their lower ends being connected with its upper
surface, and their upper ends with a chamber or box that has commu-
nication with the outlet chimney or flue. The products of combustion
pass from the fire-box up the said tubes and into the smoke box or
upper chamber, and then into the flue leading to the chimney. The
upper box is made with a cover that can be removed to get access to
the tubes, which are provided, if required, with covers or dampers to
regulate the draught through them.
Fig. 1 is an end elevation, and Fig. 2 is a longitudinal elevation in
section of a heating apparatus, suitable for stoving hats and heating

page_text: rooms or chambers; but in Fig. 2, there is an external casing shown,
which is not required for heating the air of stoves or chambers directly.
The air to support combustion is brought by a pipe, channel, or
flue (a) into a cavity 6 under a plate c, which may rest on any suitable
foundation, and in this base plate there are holes on three sides which
communicate with the three hollow sides of the base box d, which forms
the ash place. In the sides of the base box (d) there are holes (d³)
which allow the air to enter the ash place under the bars, which is kept
closed by a door (d¹) or plate suspended from pins or hooks, which plate
can be removed when the ashes are to be taken away, or at other times,
if required. e is the fire-box; f, the grate bars; e¹, the fire door; e², the
top of the fire-box; g, tubes secured in it, which are at their ends
upper
secured in a smoke-box h, from which the products of combustion pass
in any convenient direction through a pipe ¹ to the flue of the chimney.
The shape of the fire-box (e) and of the heating surfaces (g and h) may
be varied according to the use to which the stove is to be applied, and
may be arranged with shelves or recesses, upon which smoothing irons
are placed to be heated, which smoothing irons are used in the manu-
facture of hats, and for other purposes, so long as the air for supporting
the combustion of the fuel is brought from the exterior of the chamber
in which the stove or heating apparatus is fixed or used.
When air is required to be heated and supplied through a pipe, flue,
or channel to heat chambers or buildings, or for heating conservatories,
or other purposes, the apparatus is placed in a small chamber, which by
preference should be below the chamber, building, or conservatory to
be heated, and the upper part of this small chamber has an outlet flue
or pipe to convey the heated air from it to the building to be heated,
and an inlet for air to be heated, the going out of the air being regulated
by a valve or damper. Or the apparatus is arranged, as shown in Fig. 2,
enclosed in a casing k, which is in communication with the hollow base
box d, which thus supplies both the air for combustion and that which
is to be heated by passing between, over, or in contact with the heated
surfaces of the fire-box, tubes, and smoke box, the products of com-
bustion passing to the chimney, while the heated air is taken by a pipe
or flue to the building or place where it is required.
I have now particularly described the nature of my Invention, and
the manner of carrying the same into effect, and claim as my Invention,―
