Improvements in and connected with the Manufacture of
Confections.
I WILLIAM BRIERLEY of The Borough Brass Works Rochdale in the County
of Lancaster Brass Founder do hereby declare the nature of this invention to be
as follows:-
:-
This invention relates to the manufacture of and apparatus for boiling or cooking
solutions or compounds of sugar glucose or other ingredients used for the
manufacture of sweetmeats or confections which are known in the trade as boiled
goods.
It is well known to persons engaged in the confectionery industry that the sugar
undergoes two boiling operations first in a steam jacketed pan or steam pan and
secondly in open pans on open fires in order to obtain the proper consistency of the
sugar and the requisite heat to attain such consistency.
It is of vital importance that the compound be heated to a high temperature
particularly so when the water or moisture is evaporated therefrom in order that
the same may quickly assume a mucilaginous state or attain the proper consistency
so that when cooled or converted into the congealed state may be hard and of good
colour these desirable qualities being necessary so that the manufactured confections
may not become affected for a long period by atmospheric influences such as heat
or moisture and may not become adhesive or objectionable to manipulate or handle
during transport.
The sole object and purpose of this my invention therefore is to provide an
apparatus capable of withstanding and operating with steam of high temperature
and means whereby the sugar may be heated or the boiling effected in one and the
same pan and consequently by such means the contents in the pan may be raised to
a high temperature.
Within a circular or other conveniently shaped vessel or shell having a plain or
even surface and supported by means of trunnions resting in suitable bearings on
standards about the axes of which it is free to move or turn I place the copper or
boiling pan of smaller diameter than the shell having a flange or annular rim the
surface of the pan being indented or corrugated such corrugated form being an
essential element in the carrying out of my invention as by such form I am enabled
to obtain a large area of heating surface at the same time combining great strength
the annular rim is allowed to rest on the edge of the shell thus a cavity or space is
formed around the pan with which cavity a communication is effected with a boiler
generating steam at high temperature by means of connecting pipes an outlet
orifice also being provided leading from the cavity to a suitable steam trap. 1 also
convey from the boiler a tube terminating within the cavity arranged to pass
around the pan in any convenient manner the said tube may terminate with a
perforated piece which I term a rose which may be a plate or plates or spray
tubes or pieces whichever arrangement be employed the continuation of the tube
from the boiler or the terminating spray pieces plate or plates the surface or
surfaces presented or opposite to the surface of the pan being provided with a
number or series of apertures or perforations.
"
The operation of this invention is as follows.
I admit or allow steam to pass from the boiler to the cavity which steam
circulates around the pan and the perforated spray plate or plates but when the
boiling of the contents has reached what I may term the critical or crucial point,

page_text: that is when the moisture or water has been evaporated therefrom the temperature
and supply of steam to the cavity may be augmented by admitting steam through
the heated spray or rose the consequence is that dry steam is directed against the
pan the temperature of the contents of the pan being immediately raised and quickly
converted into the mucilaginous state or consistency so requisite in order to attain
the most beneficial results as hereinbefore referred to.

COMPLETE SPECIFICATION.
Improvements in and connected with the Manufacture of
Confections.
I WILLIAM BRIERLEY of The Borough Brass Works Rochdale in the County
of Lancaster Brass Founder 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 :-
This invention relates to apparatus for boiling solutions or compounds of sugar,
glucose, and other ingredients used for the manufacture of sweetmeats or confections
which are known in the trade as boiled goods.
It is well known to persons engaged in the confectionery industry that the sugar
undergoes two boiling operations, first, in a steam jacketed pan or steam pan, and
secondly, in open pans on open fires in order to obtain the proper consistency of the
sugar and the requisite heat to attain such consistency. It is of vital importance
that the solution should be heated to a high temperature particularly so when the
water or moisture is evaporated therefrom in order that the same may quickly
assume the mucilaginous state or attain the proper consistency so that when cooled
or converted into the congealed state may be hard and of good colour these desirable
qualities being necessary so that the manufactured confections may not become
affected by atmospheric influences and may not become adhesive or objectionable to
manipulate or handle (which high temperature is now attained and accomplished by
the aid of open fires or secondary operation herein before referred to).
The object and purpose of this my invention is to provide an apparatus or means
capable of conducting the boiling operation in one pan without the aid of open fires
and thus to effect a saving of labour which I accomplish by means of a steam-
jacketed pan as now used but capable of operating with steam of high pressure
being simply a jacketed pan of stronger construction than hitherto used but in
conjunction with devices or arrangement by which means the temperature of the
contents of the pan may be increased at the proper period that is when the water is
evaporated from the solution or may be at the will of the attendant in order to
accelerate the boiling thereof and to obtain the most beneficial results.
In order that a clear understanding may be had as to the manner of carrying my
invention into effect I have hereto annexed a sheet of drawings which sheet fully
illustrates the details of my said invention and marked with letters of reference
similar letters referring to like parts in the figures therein shown.
Fig. 1, is a sectional front elevation of my invention.
Fig. 2, is an end elevation of Fig. 1.
Within a circular or other shaped vessel a of copper having an even surface and
provided with trunnions b' braised in one piece with the vessel and loosely
mounted in bearings provided in standards so as to be free to turn about the axis
of the trunnions bb' as required when the boiling is effected or when it is desired to
pour the contents of the pan on to the cooling slab. I place a corrugated pan or
copper of smaller diameter than the vessel a, which form of pan is essential in
carrying out the main object of my invention riz. strength to resist steam of high

page_text: pressures and in order to obtain a comparatively greater heating surface than would
be the case with a pan having a plain or even surface and of equal diameter, the
anunlar rim d' of which pan is adapted to seat on a metal ring e which I term a packing
ring which ring is seated on an annular rim or flange a' of the outer vessel, at the
upper part or surface of the flange or rim of the pan is provided a packing ring f
upon which is seated the rim or flanged portion of the curb g, the curb and the
annular rim a-between which are interposed the packing rings-
-are secured
together by means of bolts g', and between which rings and flanges cement is
interposed. By the arrangement of attaching the pan d and the outer vessel at
their flanges in conjunction with the formation of the trunnions in one piece with
the body of the vessel a the use of soft metal or "solder" in connection with joints
or rivet holes is dispensed with consequently danger or fracture is obviated which
may occur at the joints due to the employment of steam of high temperature and
pressure in order to accomplish the boiling.
Around the pan a cavity or space is formed from which cavity extends a tube i
or auxiliary steam supply pipe through an orifice j which tube may be connected to
a steam generating vessel or boiler, the tube i terminates in the cavity under a
perforated plate or rose m the plate being braised to or with the pan.
The pan
and the outer vessel are connected together at their lower extremities
by means of a holt and plate ¹ in order to strengthen the pan when subjected to
steam pressure. The perforated surface of the rose is presented or opposite to the
underside of the pan, if desired a perforated coil may be used instead of the
perforated plate in that case the tube i would terminate with a coil which may be
of a form to accommodate the shape of the pan.
I also pass a coil into the interior of the pan through which steam or heated
media may be passed and consequently through the solution contained therein.
The operation of my invention is as follows.
Steam is allowed to pass through the orifice through the annular space; thence
into the cavity and through the coil which may be controlled by means of
suitable cocks or taps on the pipe leading into orifice », and the coil r, steam is also
allowed to pass through the tube and to be directed against the pan when the
boiling is to be completed or accelerated, the exhaust steam from the coil is passed
out at s and the exhaust steam from the cavity and the auxiliary supply tube or
rose is passed out through the hollow trunnion 6, at the exhaust extremity of each
I provide a suitable escape valve I also provide a suitable cover or hood over the
pan in order to carry off the fumes arising from the boiling solution.
Having now 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 I
claim is.
1. In combination the corrugated pan d, the coil r, orifices j and n, pipe i, rose m,
and outer vessel a by means of which combination of parts steam may be admitted
into or through the interior of the pan, and around the pan, either separately or
both at the same time also an auxiliary supply of steam may be admitted into the
cavity and directed against the corrugated pan as and for the purposes herein fully
set forth and described.
2. The auxiliary or accelerating steam supply pipe, passing through an annular
orifice and terminating with the rose m situate within the cavity has and for the
purposes herein fully specified.
3. The corrugated pan d substantially as and for the purposes herein specified.
4. The outer vessel a having hollow trunnions formed or braised solid with
the body of the vessel as and for the purposes herein specified.
5. The combination of the corrugated pan d, the pipe i with the rose m, and the
outer vessel a having trunnions formed solid or in one piece with the said vessel as
by such arrangement or combination of pan and vessel as herein described and as
shewn in the annexed drawings the use or application of soft metal known as

page_text: "solder" is obviated and thus the melting thereof at the joints due to high
temperatures of steam is avoided for the purposes herein set forth.
