A Wheel fitted with flaps or fans similar to the fan now in use is fitted at the
upper end of the main or outlet pipe with one or more encircling tubes or covers
to each of which tubes is attached another pipe which is led or carried into the
place from or into which it is desired to ventilate.
The apparatus is actuated by any suitable machinery and the action of the fan
causes and forces the current required for ventilation in the desired direction
through the ordinary intake pipe into the encircling tubes the current thus carried
in the encircling tubes by the mechanical action consequent on the removal of
the air and the necessity of the space thus caused being rapidly refilled sets up a
strong draught or current of air in each intake pipe and each encircling tube thus
causing in each encircling tube a very strong current which acts as an exhaust in
the same way as in the main pipe at the fan.
The mode of application is for the desired number of attached or intake pipes
to be placed in such a position as may be deemed desirable the fan fixed at the
upper end of the outlet pipe is then set in motion and the air carried and drawn
by such motion is forced into and through the encircling tubes creating a current
or draught in the intake pipes.
The air thus drawn by the direct action of the fan becomes a power which
creates another draught or current in each of the other intake pipes and thus
augments the actual results of the apparatus.
The apparatus is worked by any motive power and made of such character as
to exhaust steam water dust or any similar substance.

by the said William Teague in the Great Seal Patent Office on the 8th February

WILLIAM TEAGUE of the parish of Illogan in the County of Cornwall Engineer
and Mine Manager IMPROVEMENTS IN APPARATUS FOR VENTILATING PURPOSES
The apparatus is used for ventilating purposes by the process of exhaustion or
introduction of air vapor gas or steam to be as follows a Wheel fitted with flaps
or fans similar to the fan now in use is fitted at the upper end of the main or
outlet pipe with one or more encircling tubes or covers to each of which tubes is
attached another pipe which is led or carried into the place from or into which it
is desired to ventilate.
The apparatus is actuated by any suitable machinery and the action of the fan
causes and forces the current required for ventilation in the desired direction
through the ordinary intake pipe into the encircling tubes the current thus carried
in the encircling tubes by the mechanical action consequent on the removal of the
air and the necessity of the space thus caused being rapidly refilled sets up a strong
draught or current of air in each intake pipe and each encircling tube thus causing
in each encircling tube a very strong current which acts as an exhaust in the same
tube as in the main pipe at the fan.
The mode of application is for the desired number of attached or intake pipes
to be placed in such a position as may be deemed desirable the fan fixed at the
upper end of the outlet pipe is then set in motion and the air carried and drawn
by such motion is forced into and through the encircling tubes creating a current
or draught in the intake pipes.
The air thus drawn by the direct action of the fan becomes a power which
creates another draught or current in each of the other intake pipes and thus
augments the actual results of the apparatus.
The apparatus is worked by any motive power and made of such character as to
exhaust steam water dust or any similar substance.
In witness whereof I the said William Teague have hereunto set my hand
and seal this thirty first day of January in the year of our Lord One
thousand eight hundred and eighty three.
