COMPLETE SPECIFICATION.
Improvements in and relating to Sugar and Jam Pans for the
Manufacture of Confections and for Preserving Fruit.
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 more particularly to improvements in connection with
the subject matter of my former Letters Patent No. 6994 A.D. 1891 titled
improvements in and connected with the manufacture of confections.
My present improvements relate to the application of an internal steam coil
to a sugar or boiling pan or to a jam pan used for the purpose.
This invention relates to apparatus such as sugar or jam pans for boiling or
cooking solutions or compounds of sugar, glucose, or other ingredients used
for the manufacture of sweetmeats or confections, or for the preserving of fruit,
by which means I am enabled to rapidly boil solutions and attain most beneficial
results. I may also according to my arrangement, quickly cool partially, or
wholly, the solution when sufficiently boiled, and thus obviate the use and loss
of time consequent upon the employment of intermediate vessels used generally
for cooling purposes. I am also enabled according to my present arrangement,
to construct the pan of material being of light or thin section, which shall be
non-corrosive, and without the use of a steam jacket or steam cavity i.e. the
use of two pans an inner one, and an outer one, liability of accident such as
scalding by the escape of steam may be minnimised. According to my arrange-
ment I provide for the inlet or admission of steam and water into the two coils
simultaneously, or if desired water alone in the one coil or may be both coils
for cooling purposes, the admission of such steam and water or water alone as
the case may be, being effected through and by means of connections which do
not pass through hollow trunnions, but independently thereof, consequently in
the construction or arrangement of this my invention, I employ solid trunnions
or supports, whereby I dispense with joints consequently leakages, or defects
at such parts, which may occur more or less during the wear or use of apparatus
constructed having hollow trunnions as set forth and described in the specifica-
tion the subject of the before mentioned Letters Patent.
In order that my invention may be clearly comprehended I annex the accom-
panying sheet of drawings illustrating the application of my invention to a
sugar boiling or jam pan.
The drawing illustrates a sugar or boiling pan in elevation.
a, is the water inlet pipe connected at a', with a flexible connection or tubing.
so as to allow the connections or inlet pipe just referred to to move or swing
with the panc, which pan is made of aluminium of light or thin section and
of any convenient form, which; pan is arranged and free to swing in its bear-
ings, c1, c2, of the framework, and which is so arranged to allow of the pan
to be tilted for the purposes of pouring out the contents of the pan. The
tube, a, of copper or other material passes down to the coil, d, of which it forms
SD 077

page_text: part of the said coil, terminating at, d1, and connected with the outlet pipe
or connection, f, between the points, d 1, and, e, is provided a two way tap or
cock, g.
The said tube, a, is connected at, ³, to tube, h, through which steam
may be admitted into, a, from, h¹, through the medium of three way tap, h³, and
water may in like manner be admitted to, a, and, h, respectively, from a by
suitably operating the taps a², h² which tubes, a, and h, form parts of the coils, d,
and, i, which pass within and around the outside of the pan, c respectively which
coil, i, has a flat side which bears and braized to or against the pan c, and
terminates at the outlet pipe, f, into which the coil , also terminates as before
mentioned. The said coil may if desired be conveniently or suitably rivetted
to the pan.
To the tubes, a, and, h, are connected respectively at, al, and, h,
flexible water and steam metallic tubing in order to allow of the pan to swing
or tilt with its connections or attachments. The operation of my invention is
as follows. When the pan is to be used for boiling purposes the tap, h³, is
operated, steam is then admitted through pipe, h, and may be through the
junction piece, h³, into the pipe, a, consequently in such event steam would be
admitted through the inner and the outer coils, d, and, i, simultaneously by
suitably operating the tap, h². The steam or condensation water passing from
both coils into the outer pipe, f, when the tap g is suitably turned which pipe
or connection may terminate at any convenient place or caused to pass into or
through a melting pan for the purposes of melting sugar, the use of which pan
18 well known in the trade, or may be through any other cooking appliance, thus
the heat of the waste or exhaust steam may be utilised for melting or other
purposes. When it is desired to cool the boiled solution water alone may be
passed from, a', through pipe, a by operating the tap, a². If desired water may
be passed simultansly through both coils d and i by suitably operating taps a³
and thus the solution may be wholly or partially cooled within and at the
outside of the pan after cooking by steam preparatory to pouring the contents
from the pan thus the solution may be rapidly or quickly cooled by the double
process of cooling, the cooling water passing out through, f, as in the case of
the steam.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In combination the inner coil, d, the outer coil, i, the swing pan, c, with
their steam and water inlets and outlet, a, h, and, f, whereby the pan is free to
swing in its bearings, cl, 2, having solid trunnions, j, and whereby the steam
and water respectively is admitted to the coils independent of the trunnions as
and for the purposes herein fully set forth and described.
2. In combination the aluminium pan, c, the flat sided coil, i, the coil, d, with
their inlets and outlets, h, a, and, f, as and for the purposes herein fully set
forth and described.
3. In combination the coil, d, the flat sided coil, i, as and for the purposes
herein fully set forth and described.
4. The pan, c, and flat sided coil, i, as and for the purposes herein fully set
forth and described.
5. The flat sided coil, i, having steam and water inlets and outlet connec-
tions, h¹, h³, and, f, communicating with the inlet and outlet connections, a,
and, e, of an inner coil, d, as and for the purposes herein fully set forth and
described.
