PROVISIONAL SPECIFICATION.
Improvements in and connected with Pans for Boiling or Heating
Sugar or Compounds thereof, or similar substances.
We, ROBERT MORTON, and THOMAS MORTON, of Belhaven Works, Wishaw,
in the County of Lanark, North Britain, Engineers, do hereby declare the nature
of this invention to be as follows, that is to say :-
Our said invention has for its object to improve the action and increase the
efficiency of pans such as are used by confectioners for boiling or heating sugar or
compounds thereof or other similar substances.
In carrying out our invention we arrange two pans in connection with each other,
a primary pan placed at a higher level than the other so that its contents can be
run into the latter, and heated to a moderate temperature for the primary liquefying
or melting and mixing of the sugar and other ingredients.
The second pan is heated by an internal coil of unperforated steam piping,
and also by an external jacket, the supply of steam to the internal coil and to
the jacket being regulated by means of separate stopcocks or valves. Within
the jacket there is a coil of perforated piping through which the steam enters
and the action of which is to distribute the steam suitably throughout the jacket.
The primary pan is heated by means of a jacket only, such jacket however
having within it a coil of perforated piping to distribute the steam. The steam
employed to heat the primary pan is the exhaust or partly used steam from the
other pan, the end of the internal coil of the latter communicating by a pipe
with the jacket of the primary pan, and the same pipe also receiving steam
through an orifice of suitable size, from the jacket of the second pan.
Considerable economy and convenience arise from this arrangement, and when a
charge is being boiled or heated in the second pan a succeeding charge is being
prepared in the primary pan.

Improvements in and connected with Pans for Boiling or Heating
Sugar or Compounds thereof, or similar substances.
We, ROBERT MORTON and THOMAS MORTON of Belhaven Works, Wishaw, in
the County of Lanark, North Britain, Engineers, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our said invention has for its object to improve the action and increase the
efficiency of pans, such as are used by confectioners for boiling or heating sugar or
compounds thereof or other similar substances.
In carrying out our invention, we have two pans in connection with each other-
a high pressure jacketed steam pan A and a low pressure jacketed steam pan B.
Pan A is fitted with 2 coils, one perforated coil K between the jacket and pan and
a coil L inside the pan. The low pressure pan B is fitted with a perforated coil M
only, between jacket and pan.
The pan B is connected by steam pipe E which conveys exhaust steam from
pan A through reducing valve F into the perforated coil M of pan B, by means of
which the sugar and other substances are melted or partly boiled in pan B, and, by

boiled to the required degrees. The thermometer N on pan A, is carried to bottom
of said pan, and is for the purpose of showing the temperature of contents in pan.
G is steam pipe from boiler.

.. Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed; we declare that what we,
claim is ;-
= 1st. The combination of a high and low pressure pan, as shewn, in accompanying
drawings, by means of which, the exhaust steam from high pressure pan is utilised
in low pressure pan, thus effecting a great saving in steam,
2nd. Having 2 coils in high-pressure pan ie., a perforated coil between the jacket
and pan and a plain or unperforated coil.. inside the pan; which effects a much
quicker boil than is possible with a single-coil pan.
