PROVISIONAL SPECIFICATION.
Improvements in Steam Pans for Boiling Sugar and other Substances.
I, JAMES LUKE COLLIER, of Wellington Works, River Street, Rochdale, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to steam heated pans for rapidly boiling sugar, glucose
and other substances and more particularly designed for use in the manufacture
of confectionery, jam, and the like.
According to my invention I employ a hemispherical vessel within which I place
another similarly shaped vessel having an upwardly projecting dome or other
shaped chamber, a space being left between the two vessels. In the said chamber
and space I arrange a perforated steam coil or its equivalent whereby a large
amount of heating surface is provided, the steam is equally distributed over the
surface of the pan and I am enabled to dispense with the steam coils sometimes
used inside the inner vessel and consequently obtain a clearer space inside the
pan.

Improvements in Steam Pans for Boiling Sugar and other Substances.
I, JAMES LUKE COLLIER, of Wellington Works, River Street, Rochdale, in the
County of Lancaster, Engineer, 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: -
My invention relates to steam heated pans for rapidly boiling sugar, glucose
and other substances and more particularly designed for use in the manufacture
of confectionery, jam, and the like.
According to my invention I combine with the usual jacketted vessel an
upwardly projecting chamber, of dome or other shape, which communicates with
the steam jacket and has within it a perforated steam pipe or the like.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing which represents in sectional view a pan
provided with my improvements.
a is the outer casing or jacket of the boiling vessel carried upon trunnions, b is
the boiling vessel proper supported in the said outer vessel with the space e

page_text: between it and the said casing and d is the perforated steam coil arranged in the
said space and supplied with steam through one of the trunnions, the steam escaping
through the other trunnion, all the said parts being arranged in the usual manner.
e is the chamber which, according to my invention, I arrange within the boiling
vessel 6, the said chamber being in open communication with the space c and having
a pipe connected with the perforated steam coil d projecting into it. This
chamber e may be fixed in the bottom of the vessel b in any suitable manner.
shewn in the drawing, the said chamber e is provided with a neck g which extends
through an aperture in the vessel b and is fixed therein by means of a screw collar
or nut h, or, if preferred, the said chamber can be raised from the solid sheet of
conner of which the vessel b is formed.
As
With the arrangement hereinbefore described it will be understood that a much
larger amount of heating surface is provided than in the ordinary vessel
By my invention I am enabled to dispense with the use of steam coils inside
the boiling vessel proper and thereby obtain a clearer space within the said vessel
than when such internal coils are used.
Having now particularly dscribed and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The combination with a steam jacketted boiling pan of an inverted chamber
secured to or formed in the bottom of the boiling vessel and in open communication
with the jacket around the same, substantially as described.
2. The manufacture and use of steam pans for boiling sugar and other substances,
substantially as hereinbefore described and illustrated in the accompanying
drawing.
