"IMPROVEMENTS IN THE ARRANGEMENT OF COPPERS AND THE FURNACES THEREOF
FOR BOILING WORTS IN BREWING OPERATIONS AND OTHER SIMILAR PURPOSES."
+
This Invention refers to improvements in the arrangement of coppers and the
furnaces thereof to be used in brewing for boiling worts, by the employment of
which such operation is performed in a much less time than by similar apparatus as
at present arranged, whilst a considerable saving in the consumption of fuel is
effected.
.
The body of the "setting" is constructed of brick work or other suitable
material. Air is conducted by two flues from the exterior to below the grate,
whereby the bars are kept cool, a suitable door by preference arranged below the
furnace door being provided for facilitating the cleaning out of the said flues.
Immediately within the furnace door is an arch which directs the current of air as
it enters to within a short distance of the top of the bridge, which is situated at the
opposite end of the grate, whereby the said air is heated before coming into contact
with the bottom of the copper. At each side of the grate is a ledge or flat surface
which allows the fire to expand and extend to the outside of the bottom of the
copper. The most intense portion of the fire is directed by the before mentioned
bridge towards the centre of the bottom of the copper, which is the thickest part
thereof. At the back of the said bridge is arranged a chamber for the reception of
the heavy dust, and at the centre of the back of the said bridge is a partition
supported by an arch above the last mentioned chamber, such partition serving to
divide the products of combustion as they pass from the furnace. The products of
combustion having been so divided are brought into contact with the sides of the

page_text: copper by passing through flues arranged round the latter. Chambers are arranged
at the bottom of the last mentioned flues for the reception of dust, thereby
preventing loss of heating surface from accumulation of the same on the sides of the
copper. Suitable openings are provided at the back for cleaning the said side flues.
The copper is arranged on a seat formed of firebrick wall, the thickness of which is
in proportion to the size of the copper, as will be well understood. In front of the
"sturr pipe," which is constructed and arranged in the usual manner, is an arch
which protects it from the heavy fire, the latter passing underneath the said
"sturr pipe" and causing equal expansion and contraction. On the other side of
the copper opposite to the "sturr pipe" is arranged an arch which corresponds in
size and position with the latter, thus equalising the heat, the fire passing under-
neath the said two arches to the damper which is placed in front of the copper and
above the centre of the furnace door. A split is formed in the centre of the flue
opposite the damper to keep the fire from "cross cutting" when passing through
the latter to the chimney.

THOMAS BLOOM, of Boston, in the County of Lincoln, Copper Setter.
"IMPROVEMENTS IN THE ARRANGEMENT OF COPPERS AND THE FURNACES THEREOF
FOR BOILING WORTS IN BREWING OPERATIONS AND OTHER SIMILAR PURPOSES."
My said Invention refers to improvements in the arrangement of coppers and the
furnaces thereof to be used in brewing for boiling worts, by the employment of
which such operation is performed in a much less time than by similar apparatus as
at present arranged, whilst a considerable saving in the consumption of fuel is
effected.
The body of the "setting" is constructed of brick work or other suitable
material. Air is conducted by two flues from the exterior to below the grate,
whereby the bars are kept cool, a suitable door by preference arranged below the
furnace door being provided for facilitating the cleaning out of the said flues.
Immediately within the furnace door is an arch which directs the current of air as
it enters to within a short distance of the top of the bridge, which is situated at
the opposite end of the grate, whereby the said air is heated before coming into
contact with the bottom of the copper. At each side of the grate is a ledge or flat
surface which allows the fire to expand and extend to the outside of the bottom of
the copper. The most intense portion of the fire is directed by the before-
mentioned bridge towards the centre of the bottom of the copper, which is the
thickest part thereof. At the back of the said bridge is arranged a chamber for the
reception of the heavy dust, and at the centre of the back of the said bridge is a
partition supported by an arch above the last mentioned chamber; such partition
serving to divide the products of combustion as they pass from the furnace. The
products of combustion having been so divided are brought into contact with the
sides of the copper by passing through flues arranged round the latter. Chambers
are arranged at the bottom of the last mentioned flues for the reception of dust,
thereby preventing loss of heating surface from accumulation of the same on the
sides of the copper. Suitable openings are provided at the back for cleaning the
said side flues. The copper is arranged on a seat formed of firebrick wail, the
thickness of which is in proportion to the size of the copper, as will be well
understood. In front of the "sturr pipe," which is constructed and arranged in the
usual manner, is an arch which protects it from the heavy fire, the latter passing
underneath the said "sturr pipe" and causing equal expansion and contraction. On
the other side of the copper opposite to the "sturr pipe" is arranged an arch which
corresponds in size and position with the latter, thus equalizing the heat of the fire
passing underneath the said two arches to the damper which is placed in front of
the copper and above the centre of the furnace door. A split is formed in the
centre of the flue opposite the damper to keep the fire from "cross cutting” wheu
passing through the latter to the chimney.
I will now proceed to refer to the accompanying Drawings, from which the
nature of my said Invention will be more clearly understood. Figure 1 is a plan
with the copper in position, and Figure 2 is a similar view with the copper taken
out; Figure 3 is a horizontal section through the furnace; Figure 4, a front view;
Figure 5 is a section through A, B, in Figure 2; and Figure 6 is a section through
C, D, in Figure 3. The same letters of reference indicate like parts in all the
Figures. A, A, are the two flues for conducting the air to the fire bars for the purpose
of keeping them cool, C being the door provided for facilitating the cleaning out of
the said flues. D is the arch immediately within the furnace door, the bridge at
the opposite end of the grate being shown at E. F is the bottom of the copper;

page_text: G, G, are the flat surfaces on each side of the bars for allowing the expansion of the
fire to the outside of the bottom of the copper. The flue J is provided for the
reception of the heavy dust. The arch K supports the partition L, which splits the
fire and directs it into the flues O, O, to the sides M, M, of the copper; the
chambers Q, Q, at the bottom of the flues O, O, are provided for the reception of
dust as hereinbefore described. The arches R, R, on each side of the chambers Q, Q,
are provided for the purpose of cleaning. P is the seat on which the copper stands.
The arch T is made to correspond with the “sturr pipe" S on the other side to
cause equal expansion and contraction. The split U opposite the damper N is to
keep the fire from "cross cutting" as hereinbefore stated.
Having thus described and ascertained the nature of the said Invention,
and the manner in which it is to be performed, I would observe in conclusion
that what I consider novel and original, and therefore claim as constituting
the Invention secured to me by the said herein before in part recited Letters
Patent are,
The improvements in the construction and arrangement of boilers and
furnaces, substantially as and for the purposes hereinbefore described and set
forth.
In witness whereof, I, the said Thomas Bloom, have hereunto set my hand
and seal, this Twenty fourth day of May, in the year of our Lord One thousand
eight hundred and eighty one.
THOMAS BLOOM. (L.S.)
