I, RUBIN BERSON, of 343, Edgeware Road, London, W., in the County
of Middlesex, do hereby declare the nature of the said Invention for
"A NEW APPARATUS FOR THE RAPID BOLLING BY MEANS OF CHARCOAL FIRE, AND
FOR A SELF-ACTING BELLOWS FOR AËRATING THE SAME," to be as follows:-
This machine consists of the following principal parts:-(1), a part to
hold the liquid to be boiled, or different parts for boiling or baking;
(2), a grate or part to hold the fire; (3), an apparatus or part for
supplying the fire with an increased velocity of draught.
The model is constructed as follows:-A tin cylinder is taken, say, for
example, 83 inches in height and 43 diameter; this cylinder has a flat-
bottom cover on which it can stand; at about 3 from the bottom a
horizontal partition of tin is made in the cylinder, and from the center of
this partition a circle is described at the distance of one inch, within the
circumference of which a number of holes are punched, each having the
diameter of nearly of an inch. From the circumference of this circle there
arises a smaller cylinder to the height of an inch above the level of the

page_text: larger cylinder. This smaller cylinder constitutes the grate or part to
hold the charcoal fire; and the part surrounding this constitutes the part
to hold the liquid to be boiled, or different parts for boiling or baking
in compartments heated by boiling water. The larger cylinder has a
cover [or the various compartments have respectively covers or doors],
which does not also cover the smaller cylinder; it surrounds it, the
smaller cylinder projecting above it.
Respecting the Draught:- On the top of the smaller cylinder is placed
a moveable tin chymney of the height of at least 8 inches, the apex of
which is narrower than the base. In the part below the horizontal
partition there is a door.
The process of getting the draught may be obtained in various
ways. Either at the distance of 2 inches from the horizontal partition
there is a horizontal row of holes each inch diameter, one inch apart
from each other; below this row there is another row of holes, each hole
being vertically under one in the upper row; these holes are continued
through the door from the lower row to the bottom a distance of 1 inch
from the centre of the lower hole. Or, again, there being no holes an
ascending or descending tube is connected with the lower part, its
diameter at the point of connexion being equal to that of the top of
the chimney, its diameter at the other extremity being equal to that of
the base of the chimney.
Respecting the Self-acting Bellows:-This bellows will completely act
upon the principal of the wheel and axle, moved by a weight with cord
or the spring with lever. The boiler having no rows of holes hut only
one hole will, the mouth of the acting bellows being applied to it, be
supplied with an increased draught.
The machine has various appendages, not bearing upon its action, for
facilitating its use. The charcoal is lighted by a light applied through
the door, the chimney placed on, and the draught caused by one of the
given ways, the water will boil within 3 to 6 minutes. A cover placed
on the top of the chimney will mitigate, a cover placed upon the smaller
cylinder will extinguish the fire.
