PROVISIONAL SPECIFICATION.
Improvements in and connected with Furnace Pans, Coppers, and
the like.
1, JOSEPH WOOD, of 43 St. Helens Street, Ipswich, in the County of Suffolk,
Builder, do hereby declare the nature of this invention to be as follows:-
When furnace pans, coppers and the like, are fixed into the brickwork and
cemented round, there is no access to the inner flues, whatever, which consequently
get corroded round with soot, therefore there is a larger quantity of fuel, required
for heating purposes.
Now my improvement, consists of a rim, to be cemented into the brickwork, so
formed, that by taking two levers, and placing them into the slots, on the rim, the
furnace pan or copper, is easily prised out of its position, whereby full access is
obtained to the inner flues, likewise the outside of the furnace pan, or copper.
It entirely dispenses, with the dangerous and destructive practice, of discharging
gunpowder, for the purpose of clearing the flues of soot, which occasionally disturbs
the brickwork and blows out the furnace door.
When a new furnace pan or copper is required, it can be easily replaced in the
rim without the aid of a bricklayer.
Improvements in and connected with Furnace Pans, Coppers, and
the like.
I JOSEPH WOOD, of 43 St. Helens Street, Ipswich in the County of Suffolk,
Builder, 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 :-
When furnace pans, coppers and the like, are fixed into their brickwork or
masonry setting and cemented round, there is no access to the inner flues whatever,
which consequently get corroded round with soot, and then there is a larger
quantity of fuel required for heating purposes than would be the case if the flues
were clear.
According to my invention 1 secure by cementing or otherwise a rim in the
brickwork or masonry setting for the reception of the upper part or rim of the pan,
copper, or the like, there being also provided slots or devices by which the pan
copper or the like can be readily raised for removal, so that full access is obtained,
to the inner flues and likewise the outside of the pan, copper, or the like.
In the accompanying drawings I have illustrated various arrangements according
to my invention for shewing how it may be practically performed but I do not
limit myself to the precise details and forms illustrated therein and described with
reference thereto. In all the figures the part of the pan, copper or the like
shewn is marked A. and the part of the brickwork or masonry setting shewn
is marked B.

page_text: In the orifice in the brickwork or masonry to receive the pan copper or the like
is a bushing or lining, of metal carthenware or other suitable material, with
a flanged part to receive the flange or rim a of the pan copper or the like.
In Figures 1 and 3 the flange or rim a has a projecting ring or bead to enter a
corresponding recess in the flange of the bushing or lining b to give a very secure
joint. In Figure 4 the same effect is obtained by making the flange or rim of the
pan copper or the like curved and the flange of the bushing or lining b with
a projection ³ to correspond and with a recess to receive the edge a³ of the flange
or rim of the pan, copper, or the like.
Various means are shewn in the several figures for facilitating the removal of the
pan, copper, or the like. In Figure 1, there is a recess or there are recesses (62) in
which a lever or levers can be introduced beneath the flange or rim of the pan,
copper, or the like to elevate it. In Figure 2 the pan is provided with a loop or
ring or loops or rings c and in Figure 3 with a projecting piece or lug or projecting
pieces or lugs c².
In Figure 4 there is a projecting rim or a lug or there are projections or lugs (a*)
beneath which a lever or levers or the hand or hands can be inserted.
The arrangement according to this invention enables the dangerous, and
destructive, practice of discharging gunpowder for the purpose of clearing the
flues of soot, (which occasionally disturbs the brickwork, and blows out the furnace
door) to be dispensed with.
When a new furnace pan, copper, or the like, is required, the old pan, copper or
the like, can be easily removed and replaced by a new one without the aid of a
skilled workman.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A furnace pan, copper, or the like, setting provided with a bushing lining or
flange around the orifice in the brickwork or masonry for the reception of the
flange or rim or the upper part and flange or rim of the pan copper or the like
substantially as and for the purpose hereinbefore described.
2. A furnace pan, copper, or the like setting provided with a bushing lining or
flange around the orifice in the brickwork or masonry for the reception of the
flange or rim or the upper part and flange or rim of the pan copper or the like
with means for facilitating the removal of the said pan copper or the like
substantially as and for the purpose hereinbefore described.
