Improvements in and relating to Boilers of Kitchen Ranges.
JAMES WALLACE, 2, Mount Clifton, in the City of Belfast, Ireland, Gentleman,
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:
The object of the present invention, is to ensure efficient heating, of boilers in
kitchen ranges, and at the same time to effect economy in the consumption of
fuel.
This invention is applicable to all boilers at present in use, but preferable to
those of shape.
To effect these improvements I construct in the foot or base of boiler, a vertical
flue, or a series of vertical flues, I also construct in the leg of boiler, a vertical flue,
or a second series of vertical flues, which run vertically through the entire length
of leg. The first and second series of tubes have direct communication with each
other through a longitudinal flue constructed in the setting of the boiler, and directly
under the foot of boiler. This flue is provided with a soot door which opens into
the ashpit.
The flues in boiler may be either round or oval shaped and of suitable material,
such as iron, or, brass, metal or copper. They may be applied to any ordinary
boiler, by providing holes to receive them, and fixing them therein, by expanding
or otherwise, or they may be cast in the boiler.
The boiler is placed at the back of furnace, and the flame from said furnace,
passes over the top, of foot, of boiler, and descends through the first series of tubes.
The flame continues along the foot of boiler, through the longitudinal flue, and
ascends through the second series of tubes, into the chimney.
By this arrangement I derive many advantages. First I heat the top, of foot,
of boiler, second, I gain greater heating surface by the first series of tubes, third, I
gain considerable heating surface by the second series of tubes. Therefore the
water in said boiler may be heated by a minimum consumption of fuel.
In small boilers I may confine the construction of boiler to the first series of
tubes, or to a single tube.
In this case the flame from furnace, after descending the first tube, or first series
of tubes continues along the entire length of foot of boiler and ascends the back of
boiler into chimney. To facilitate this arrangement, an ordinary flue is constructed
in the brick work at back of boiler, and is in direct communication with the longi-
tudinal flue under boiler.
In conjunction with these flues I construct an auxillary flue, which forms a direct
communication, between furnace and chimney. This flue may be constructed of
metal or iron work. It is placed directly in front of the leg of boiler, and may be
loose & detachable, or it may be firmly fixed to the leg of boiler. The bottom end
of said flue has an opening into the furnace, at foot of leg of boiler. The top end
communicates with the chimney. This flue is provided with a damper. This flue
may also be constructed, either of earthenware or brickwork, where the construction
of the range permits.
The resulting advantages of this arrangement are, that I can at all times obtain
a certain and direct draught which ensures rapid fire kindling. That the heavy
smoke and un-consumed gases, are withdrawn directly from the fire.
To further illustrate my invention, I append hereto, two explanatory sheets of
drawings.

second series of tubes.
A is the first series of vertical tubes.
