BOILERS, AND FURNACES FOR THE UTILIZATION AND APPLICATION OF HEAT

"
This Invention relates to constructing furnaces for burning ordinary coal gas, or
a mixture of gas and air, or hydro-carbon gas, or any other suitable gas for heating
and cooking purposes.
For this purpose I employ by preference a circular foundation plate, but square
foundation plates, or of any other suitable shape, may be employed. The underside
of the foundation plate is made with a chamber for the gas or for the mixture of
gas and air. On the top of the foundation plate are cast plates enclosing chambers
or cells in which are fitted burners of a peculiar construction; the burners are made
cup shaped, and are drilled near the top with a series of small holes for the jets of
gas or mixture of gas and air, and to each hole is formed on the cup furrows or
openings for the passage of atmospheric air to mix with the gas or mixture of gas
and air, producing a perfect combustion with smokeless and odourless flames, and
producing an intense heat by the expenditure of a small quantity of gas, similar in
principle to the oxy-hydrogen blow pipe.
The burners are fitted in each cell and secured in the top of the foundation plate
and over the gas chamber. To this chamber is fitted a number of pipes and taps
communicating to each burner in the separate cells, and the number of cells and
burners are regulated according to the heat required, and the size of the burners,
number of holes or jets, and number of atmospheric air openings or furrows, are
regulated by the heating power required.
On the top of the plates forming the cells and vent passages is fitted a plate, the
same size as the foundation plate, the cover or plate forms the bottom of the oven
or the top of a hot plate as the case may be. The burners are fitted close under
the article being heated.
The vents are formed by passages between the cells, and small openings are made
in the centre plates of the cells for the escape of heated products of combustion
which communicate with the vents, and the vents communicate with the outer
surface or surfaces of the oven plates. The burnt or heated products of combustion

chimney assist very materially the heating power. The vents for the boiler are
formed on the outer surface of the boiler, the vent space being formed between the
outer surface of the boiler and cover or outer case, but the top cover of the cells in
this case is the bottom of the boiler which is made curved, forming a heating 5
chamber, and the bottom part of the boiler is fitted with small pipes for the escape
of the burnt products of combustion in the vents before escaping through the
chimney.
