PROVISIONAL SPECIFICATION.
Improvements in Portable Glue Pots, Plumbers' Furnaces, and
the like.
I, JOHN JAMES ROYLE of Dalham Engineering Works, Great Bridgewater
Street, Manchester, Engineer, do hereby declare the nature of my said invention to
be as follows:
The object of my invention is the construction of a self contained, self heating
and therefore portable glue pot which can without risk of fire be carried from
place to place.
In carrying out my invention 1 surround the water-containing vessel common to
glue pots with another and outer casing wherein I fit a grate or fire basket capable
of holding a supply of carbonaceous fuel consisting of charcoal or other carbonaceous
matter highly compressed and which has the property of burning with great
regularity and is free from smoke or objectionable fumes. Said grate is immediately
under the bottom of the water containing vessel. The fire basket may take the
form of an additional but shorter casing with its rim resting upon the rim of the
first mentioned and outer casing. Inlet and outlet openings are provided for
the inlet of cold air and the outlet of the products of combustion and either one or
both of such openings are capable of regulation so as to control the rate of com-
bustion. Or this may be more cheaply and conveniently effected by making the
openings of the right size to support a proper rate of combustion when the glue
has been heated up and to quicken the combustion on first heating up I make the
water casing capable of elevation onto lugs suitably disposed to receive it and thus
provide a quick draft by temporarily enlarging the outlet. Handles are fitted to
the casings at convenient parts.
The same arrangement of heating can be applied to compound glue pots when
several pots of the same or varying sizes are combined in one stand. The casing
would be varied in form to suit the requirements of the pots.
The kindling and replenishing of the fuel is effected by removing the water
containing vessel and the ashes falling underneath are removed by the removal of
the fire basket or grate.
It will be obvious that this apparatus affords a very convenient way of heating
or keeping hot a portable supply of water for domestic or other purposes.
By emitting the water containing vessel the same arrangement of furnace may
be used for melting and transporting metals, say for plumbing and for other
similar purposes.

Improvements in Portable Glue Pots, Plumbers' Furnaces, and
the like.
I, JOHN JAMES ROYLE of Dalham Engineering Works, Great Bridgewater
Street, Manchester, Engineer, 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:-
The object of my invention is the construction of a self contained, self heating.
and therefore portable glue pot which can without risk of fire, be carried from
place to place.
And in order that my said invention shall be the more readily understood and
carried into practical effect. I have hereunto annexed a sheet of drawings and will
now proceed to describe the same with the assistance of the various figures and
letters of reference marked thereon.
Fig. 1 is an exterior view and Fig. 2 a sectional view of my improved portable
self heating glue pot or kettle.
In both views (A) is the usual water container common to glue pots and
containing the glue receptacle (B) wherein is placed the glue to be heated. The
container (A) has a rim (A¹) cast or formed on it and rests within a fire basket (C)
in such a manner that a passage (X) is left (as shewn by the arrows) and for this
purpose the rim (A¹) has distance pieces (A2) cast upon it. The fire basket (C) is
provided with a perforated bottom (D) upon which the burning carbonaceous
matter is placed and the entire fire basket rests within an outer casing (E) designed
to isolate the fire basket and diminish the risk of fire by anything coming into
contact with it. Air openings (F) are made in the upper part of the casing (E)
and the course of the air and products of combustion is clearly shewn by the arrows.
In using the glue pot the pieces of carbonaceous fuel are first ignited by throwing
them into a fire, or in any other convenient manner and are then placed upon the
grate (D). This class of fuel has the property of burning with great regularity
and certainty and by proportioning the size of the openings admitting air into, and
the products out of, the fire basket, a rate of combustion is easily found which will
keep the contents of the water container (A) steadily at the boil for several houra
without attention. The combustion may be quickened by raising the coutainer (A)
out of the fire basket (C) a short distance, and lugs or raised pieces may be
provided to support it in the raised position, though I have not found this
absolutely necessary in practice. The glue kettle as drawn answers every
practical requirement. The usual handles are fitted to the several parts as
illustrated.
By omitting the glue container the apparatus affords a convenient means of
keeping a small quantity of water at the boil for many useful purposes, such as for
vaporising in rooms and for use as a bronchitis kettle. Also, by enlarging the air
ways, the container (A) may be used to melt and transport lead for plumbers' use,
so forming a portable plumbers' furnace.
Having thus particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed' I declare that what 1
claim is
The fire basket (C) in combination with the outer casing (E) air ducts (F)
and (X) for heating the container (A) as and for the purposes set forth.
