Chancery Lane, in the County of Middlesex, Engineer, for the Inven-
tion of "IMPROVEMENTS IN VESSELS OR APPARATUS FOR MELTING SEALING
WAX, GLUE, OR OTHER SUBSTANCES."-A communication from abroad by
Frederick Kührmann, of Rosslau on the Elbe, in the Kingdom of
Prussia.
Sealed the 2nd March 1866, and dated the 5th September 1865.
PROVISIONAL SPECIFICATION left by the said William Bünger at the
Office of the Commissioners of Patents, with his Petition, on the
5th September 1865.
I, WILLIAM BÜNGER, of 34, Southampton Buildings, Chancery Lane, in
the County of Middlesex, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN VESSELS OR APPARATUS FOR MELTING SEALING
WAX, GLUE, OR OTHER SUBSTANCES," to be as follows:-
These improvements relate to the arrangement and construction of vessels
or apparatus to facilitate the melting of sealing wax, glue, or other sub-
stances, so as to afford greater convenience and economy in sizing such
materials..

page_text: For this purpose an external vessel (by preference of conical form furnished
with a suitable handle) is employed, having a door on one side thereof for
introducing a spirit or other lamp into the interior. Holes or apertures for
the admission of air are pierced through the lower part of this vessel, there
being other holes or apertures near the upper part thereof for the escape of
the heated air and products of combustion. Upon the upper rim, and
descending into this outer vessel, an inner vessel is supported, consisting of a
central chamber partly surrounded by a conical-shaped jacket, the smaller
part of the cone being downwards, thus forming a space between it and the
outer vessel. The wax, shellac, or other substance of a like nature to be
melted is placed in the space or jacket surrounding the central vessel; and
as it melts from the heat of the spirit lamp or gas jet 'underneath it flows
through holes or openings formed around the inner or central chamber
into the bottom or lower part thereof, the bottom of the central vessel being
by preference formed double or with a space between them to prevent the
burning of the wax or other materials when melted. For the purpose of
melting or dissolving glue or other substances of a like nature the holes
forming a connection between the jacket and the central vessel cor chamber
are dispensed with, water being introduced into the jacket or space around the
centrál vessel. By the use of the ordinary-melting pots or vessels the wax
'or other materials are liable to boil over or to be burnt or otherwise vinjured,
thus causing dangerous conflagrations; but by the use of the improved
arrangement of apparatus herein described the component parts of the wax
or other materials are not liable to be decomposed by overheating or discolored
by smoke, in consequence of which a cheaper quality of wax is found to
answer the purpose of more costly materials, owing to its adhesive properties
not being subject to injury in the process of melting; the apparatus also
affording great facility in sealing bottles or packets for manufacturing -or
commercial purposes.
SPECIFICATION in pursuance of the conditions of the Letters, Patent, filed
by the said William Bünger in the Great Seal Patent Office on the
5th March 1866.
TO ALL TO WHOM THESE "PRESENTS SHALL COME, "I, "WILLIAM
BÜNGER, of 34, "Southampton "Buildings, Chancery Lane, in "the County of
Middlesex, Engineer, send greeting.
WHEREAS Her most "Excellent Majesty' Queen Victoria, 'by 'Her Letters
Patent, bearing date the Fifth day of September, in the year of our Lord One

page_text: thousand eight hundred and sixty-five, in the twenty-ninth year of Her reign,
did; for Herself, Her heirs and successors, give. and grant unto me, the said
William Bünger, Her special licence. that I, the said William Bünger,
my executors, administrators, and assigns, or such others, as I, the said William
Bünger, my 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 Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN VESSELS OR
APPARATUS FOR MELTING, SEALING WAX, GLUE, OR OTHER SUBSTANCES," a com-
munication to me from abroad by Frederick Kübrmann, of Rosslaw on the
Elbe, in the Kingdom of Prussia, upon the condition (amongst others) that,
I, the said William Bünger, my executors, or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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. William Bünger, do hereby declare the
nature of the said Invention,, and, in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
.
These improvements relate to the arrangement and construction of
vessels or apparatus to facilitate the melting of sealing wax, glue, or other,
substances, so as to afford greater convenience and economy in using such
materials.
For this purpose an external vessel (by preference of conical form
furnished with a suitable handle) is employed, having a door on one side
thereof for introducing a spirit or other lamp into the interior. Holes or
apertures for the admission of air are pierced through the lower part of this
vessel, there being other holes or apertures near the upper part thereof for
the escape of the heated air and products of combustion. Upon the upper rim
and descending into this outer vessel an inner vessel is supported, consisting
of a central chamber partly surrounded by a conical-shaped jacket, the smaller
part of the cone being downwards, thus forming a space between it and the
outer vessel. The wax, shellac, or other substance of a like nature to be
melted is placed in the space or jacket surrounding the central vessel, and as
it melts from the heat of the spirit lamp or gas jet underneath it flows
through holes or openings formed around the inner or central chamber into

page_text: the bottom or lower part thereof, the bottom of the central so being by
preference formed double or with a space between them to prevent the burning'
of the wax or other materials when melted.
And in order that the Invention may be fully understood and readily carried
into practice, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shows an external view of a vessel or apparatus suitably arranged
and constructed according to this Invention for melting sealing wax, shellac,
or other similar substances which do not require a water jacket around the
melting pot or vessel; Figure 2 shows a section of the melting pot or vessel
separately.
a, a, is an external vessel (by preference made of tinned iron) furnished
with a door a¹ for the introduction of the spirit or other suitable lamp b, shown
in dotted lines, or a gas jet or burner may be substituted for the lamp 6.
a, a, are holes or apertures for the admission of air, a³, a³, being other
holes or apertures formed in the upper part of the vessel a, a, for the escape
of the heated air and products of combustion. is the melting pot or vessel
surrounded with the conical-shaped jacket e¹, which communicates with the
interior of the central vessel c by means of the holes or openings c³ formed
around its circumference. The wax or other similar substance to be melted
is placed in the outer chamber or jacket c', and as it melts it flows through
the holes or apertures c² into the inner vessel c ready for use. The bottom of
the inner vessel it is preferred to form double or with a space between the
two plates of metal as shown, in order to avoid the risk of overheating or
burning the melted wax or other substance contained in the vessel c. For
the purpose of melting or dissolving glue or other substances of a like nature
the holes forming a communication between the jacket c¹ and the central
vessel or chamber o are dispensed with, water being introduced into the jacket
or space around the central vessel. By the use of the ordinary melting
pots or vessels the wax or other materials are liable to boil over or to be burnt
or otherwise injured, thus causing dangerous conflagrations; but by the use
of the improved. arrangement of apparatus herein described the component
parts of the wax ar other materials are not liable to be decomposed by over-
heating or discolored by smoke, in consequence of which a cheaper quality of
wax is found to answer the purpose of more costly materials, owing to its
adhesive properties not being subject to injury in the process of melting; the
apparatus also affords great facility for sealing bottles or packets for manufac-
turing or commercial purposes.

page_text: Having thus described the nature of the Invention, and the manner of
carrying the same into practice, it should be clearly understood that the
Invention is not confined to the exact details herein shown and described; but
that which is intended to be claimed under these Letters Patent is, the con-
struction and arrangement of vessels or apparatus for melting sealing wax,
glue, or other substances as herein described.
In witness whereof, I, the said William Bünger, have hereunto set
my hand and seal, this Fifth day of March, in the year of our
Lord One thousand eight hundred and sixty-six.
WILLIAM BÜNGER. (L.s.)
