CERTAIN IMPROVEMENTS IN THE CONSTRUCTION AND APPLICATION OF APPARATUS FOR VENTILATION
Year: 1883

page_text: LETTERS PATENT to Thomas Edward Bladon and William Matthews both of
Birmingham in the County of Warwick for an Invention of "CERTAIN
IMPROVEMENTS IN THE CONSTRUCTION AND APPLICATION OF APPARATUS FOR
VENTILATION"
PROVISIONAL SPECIFICATION left by the said Thomas Edward Bladon
and William Matthews at the Office of the Commissioners of Patents on the
17th November 1883.
THOMAS EDWARD BLADON and WILLIAM MATTHEWS both of Birmingham in the
County of Warwick " CERTAIN IMPROVEMENTS IN THE CONSTRUCTION AND
APPLICATION OF APPARATUS FOR VENTILATION."
'
This our invention relates to the construction, combination, or arrangement of
parts of apparatus for ventilation, for the removal or extraction of Vitiated Air
from Buildings and constructions generally either above or below ground, rooms,
railway and private carriages, ships, mines, sewers, and other places, also for the
removal or transference of gases or chemical vapours from one chamber or place to
another.
:
In constructing our Ventilator or air or gas removing apparatus we use a fan
constructed with inclined vanes of any shape or configuration, and number most
suitable to our requirement, and working in connection with which is a tube for
conveying away the vitiated or other air or vapour required to be removed. This
fan has rotatory motion imparted to it (by one mode) by a train of clock work (by
another mode) Electro Motor, or Magneto Electric Motor or any motive power
dependant upon Electricity or magnetism for its driving power.
In cases where clock work is used as the motive power and the apparatus is
fixed at such a point as not to be easily accessible for winding by a key in the
ordinary way we wind it by pulling at a tape, cord, or chain which is wound
round a barrel containing a spring, or winding up a weight, the said barrel being
provided with a ratchet.
In any case the fan driven mechanically or otherwise acts by causing the
movement of a current of air in a direction at right angles to the plane of its
rotation.
The whole is secrated in a case suitable to its application.

by the said Thomas Edward Bladon and William Matthews in the Patent Office
on the 16th May 1884.
THOMAS EDWARD BLADON and WILLIAM MATTHEWS both of Birmingham in the
County of Warwick CERTAIN IMPROVEMENTS IN THE CONSTRUCTION AND
APPLICATION OF APPARATUS FOR VENTILATION.
Our invention relates to the construction combination or arrangement of parts
of apparatus for ventilation for the removal or extraction of vitiated air from
Buildings and constructions generally either above or below ground rooms, railway
and private carriages, ships, mines, sewers and other places also for the removal
or transference of gases or chemical vapours from one chamber or place to another,
In constructing our ventilator or Air or Gas removing apparatus we use a fan
constructed with inclined vanes of any shape or configuration and number most
suitable to our requirements and working in connection with which is a tube for
conveying away the vitiated or other air or vapour required to be removed-This
fan has rotatory motion imparted to it (by one mode) by a train of clock work (by
another mode) Electric motor, magneto electric motor, or electro magnetic motor
or any motive power dependant upon electricity or magnetism for its driving
power
In cases where clock work is used as the motive power and the apparatus is
fixed at such a point as not to be easily accessible for winding by a key in the
ordinary way we wind it up by pulling at a tape, cord or chain which is wound
round a barrel containing a spring or by winding up a weight, the said barrel being
provided with a ratchet and click
•
In any case the fan driven mechanically or otherwise acts by causing the
movement of a current of air in a direction at right angles to the plane of its
rotation
The whole is secreted in a case suitable to its application.
Having now described the nature and object of our invention and the manner
in which the same is to be performed we wish it to be understood that we claim as
our invention for Improvements in the construction and application of apparatus
for ventilation hereinbefore described (that is to say) The construction and use of
a fan having inclined vanes, working in connection with a tube for conveying away
vitiated air or vapour for more perfect ventilation, the same having rotatory move-
ment and dependant for a motive or driving power upon a train of clockwork or
its equivalent) or electric motor, magneto-electric motor, or Electro-magnetic motor
or any motive power dependant upon electricity or magnetism; constructed,
arranged and working substantially as and for the purposes above described and
set forth
In witness whereof we the said Thomas Edward Bladon and William Matthews
have hereunto set our hands and seals the 15th day of May in the year of our Lord
1884.
