Year: 1877

page_text: LETTERS PATENT to Samuel Padley, of Nos. 29 and 31, Well Road, Heeley, in
the Parish of Sheffield, County of York, Silversmith, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF URNS AND OTHER VESSELS EMPLOYED
FOR HEATING LIQUIDS."
Sealed the 6th November 1877, and dated the 7th May 1877.
PROVISIONAL SPECIFICATION left by the said Samuel Padley at the Office
of the Commissioners of Patents on the 7th May 1877.
SAMUEL PADLEY, of Nos. 29 and 31, Well Road, Heeley, in the Parish of Sheffield,
County of York, Silversmith. " IMPROVEMENTS IN THE MANUFACTURE OF URNS
AND OTHER VESSELS EMPLOYED FOR HEATING LIQUIDS."
My Invention has for its object the construction or manufacture of urns or other
heating vessels in such a manner as to adapt them for heating liquid or jelly-like
substances, by means of a lamp or other suitable heating apparatus external to the
chamber containing the liquid or substance to be heated; and my Invention
consists in forming round the chamber containing the liquid to be heated or kept
hot a hot-air chamber or chambers capable of receiving heat, as required, from
a lamp or other suitable heating apparatus enclosed at the lower part of the
urn or vessel, or otherwise arranged so as to convey heat to the said hot-air
chamber.
Apertures or perforations are formed at the lower part of the urn or vessel for
the admission of external air at such part leading to the hot-air chamber or chambers,
and an opening or openings is or are formed at the top of the said chamber or
chambers for the escape of heated air and vapour as required.
By means of the above arrangement the liquid or substance contained in the
closed inner chamber of the urn or vessel becomes heated or is kept hot by means

page_text: of the heat communicated to such inner chamber from the hot-air chamber or
chambers surrounding the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Samuel Padley in the Great Seal Patent Office on the 7th November
1877.
SAMUEL PADLEY, of Nos. 29 and 31, Well Road, Heeley, in the Parish of Sheffield,
County of York, Silversmith. "IMPROVEMENTS IN THE MANUFACTURE OF URNS
AND OTHER VESSELS EMPLOYED FOR HEATING LIQUIDS."
My Invention of "Improvements in the Manufacture of Urns and other Vessels
Employed for Heating Liquids" has for its object the construction or manufacture
of urns or other heating vessels in such a manner as to adapt them for heating
liquids or jelly-like substances by means of a lamp or other suitable heating
apparatus external to the chamber containing the liquid or substance to be heated;
and my Invention consists in forming round the chamber containing the liquid to
be heated or kept hot a hot-air chamber or chambers capable of receiving heat, as
required, from a lamp or other suitable heating apparatus enclosed at the lower
part of the urn or vessel, or otherwise arranged so as to convey heat to the said
hot-air chamber.
Apertures or perforations are formed at the lower part of the urn or vessel for
the admission of external air at such part leading to the hot-air chamber or chambers,
and an opening or openings is or are formed at the top of the said chamber or
chambers, for the escape of heated air and vapour as required.
By means of the above arrangement the liquid or substance contained in the
closed inner chamber of the urn or vessel becomes heated or is kept hot by means
of the heat communicated to such inner chamber from the hot-air chamber or
chambers surrounding the same.
In order however that my Invention may be fully understood, I will describe it
more particularly by the aid of the accompanying Drawing, in which is represented
in vertical section an urn constructed in the manner above referred to.
A is the closed inner chamber for containing the liquid substance required to be
heated or kept hot. This chamber is surrounded by the chamber or chambers B, B,
to which is supplied the requisite amount of heat from a lamp, as at C, or any
other suitable heating apparatus. At D, D, are apertures for the admission of
external air, and at E, E, there are others for the escape of heated air and vapour,
as required. The circle at F shows the position of the ordinary tap for drawing off
the heated liquid.
In ordinary cases the lamp will be fixed to the stand G and the urn placed
thereon and locked; and when the bottom of the urn or vessel is united to the
stand, in order to suit particular designs, the foot of the urn or vessel may be fluted,
and some of the flutes cut out, so as to insert the lamp sideways, giving that part
the appearance of a drawer; but these arrangements may be varied.
It will be obvious that the heat admitted from the lamp or other heating
apparatus at C will pass into the hot-air chamber or chambers B, B, by which
means the closed inner chamber A will be surrounded by a jacketing of heated
air, whereby the liquid or substance contained therein will be heated or kept hot,
as required.
The advantage of the arrangement above described is, that it readily admits
of a smaller or greater amount of heat being applied to or kept up in the
chamber A.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, I hereby declare that what I claim as of my Invention is,

page_text: the construction of urns and other heating vessels with a hot-air chamber or
chambers surrounding a closed inner chamber, in the manner and for the purpose
herein-before described.
In witness whereof, I, the said Samuel Padley, have hereunto set my hand
and seal, the Third day of November, in the year of our Lord One thousand
eight hundred and seventy-seven.
Witness,
RICHARD HOWE,
Clerk to Mr. Holmes,
