DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] A variable air intake control for rapid fire starting (10) for use in a
solid
fuel burning appliance (12) is comprised of a pipe member (14), a gate
member (16), and a chamber member (18).

CA 02847488 2014-03-26

[0024] The gate member (16) controls the size of the opening of an air intake
(26). The air then travels through the chamber member (18) before
entering the pipe member (14) located at the opposite end of the
chamber member (18).
5[0025] The opening and closing of the gate member (16) is done by way of a
connector member (20) which connects the gate member (16) to an "L"
shaped gate (22) located on a primary air supply (24). The primary air
supply (24) is described in patent US7,325,541, also by this inventor
and as such, need not be further discussed herein.
10[0026] A user first activates the connector member (20) manually when
starting
a fire, but as the burning progresses and the temperature rises, the connector

member (20) is being actuated by the "L" shaped gate (22) and reduces the
burn rate to the preset burn rate determined by the primary air control,
without
any further intervention by the user.
15[0027] As to a further discussion of the manner of usage and operation of
the
present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.
[0028] With respect to the above description then, it is to be realized that
the
20 optimum
dimensional relationships for the parts of the invention, to

CA 02847488 2014-03-26
7
include variations in size, materials, shape, form, function and manner of
operation, assembly and use, are deemed readily apparent and obvious
to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention.
[0029] Therefore, the foregoing is considered as illustrative only of the
principles of the invention. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not desired to
limit the invention to the exact construction and operation shown and
described, and accordingly, all suitable modifications and equivalents
may be resorted to, falling within the scope of the invention.
