IMPROVEMENTS IN VENTILATING APPARATUS
Year: 1884

page_text: We, CHARLES LAWRENCE, Manufacturer, and THOMAS FITZ GERALD WINTOUR,
Ventilating Engineer, c/o Messrs. Day, Davies, & Hunt, Patent Agents, 321, High
Holborn, in the County of Middlesex, do hereby declare the nature of our Invention
for "IMPROVEMENTS IN VENTILATING APPARATUS" to be as follows:-
:
This Invention relates to improvements in ventilating apparatus, and has especial
reference to certain improvements upon or in relation to the Invention described in
the Specification of Letters Patent, No 746, dated 16th February, A.D. 1882.
granted to Thomas Fitz-Gerald Wintour, one of the present Applicants.
The object of the present Invention is to extend the Application of the principle
of action described or referred to in such Specification; and to make it more
generally applicable and serviceable to the same or other uses than described or
referred to in such Specification, in other ways and by other means applicable
otherwise than therein described.
The special object sought to be attained by the means described in such
Specification:-and by those improved means herein described, is to attain a
perfect system of ventilating rooms, houses, and other enclosed apartments,
buildings, articles, or places, by a side or lateral action and exchange of the air
through wire gauze or other finely perforated surfaces which permit of a gentle
and continuous exchange of air, but prevent draught.
The acting ventilating surfaces of the ventilator (other than the plane glass or
metal ends or parts) have hitherto been disposed in a cylindrical, conical, or other
analogous manner, (excepting in certain particular applications,) and in applying
such particular formations of ventilators it is often found necessary that the part
to which the ventilator is required to be applied has to be cut or otherwise made
of corresponding formation, which in some cases is objectionable, and in others
cannot well be done, and this detracts from the application and full utility of the
said Invention.
The especial object of the present improvements is to remedy such objections, in
order that the application of the principle of the said Invention may be extended
as aforesaid, and the full utility thereof attained; and so that ventilators having
the same principle of action may be constructed of other forms than described in
such Specification, and of such forms as may be required for any particular

page_text: application, and so as to avoid its being necessary to adapt the part to which the
ventilator is to be applied to the particular form of. ventilator, as has as aforesaid,
been hitherto necessary.
A principal feature of the present Invention consists in the disposal of the said
perforated or equivalently formed acting ventilating surfaces in a longitudinal or
plano direction set at an inclination preferably of about 45 degrees to the surface
to which it is applied. This arrangement is however susceptible of certain
subsidiary modifications, for instance, the plane surface may be set at right angles
or at any other angle that 45 degrees as aforesaid, but the latter angle is preferred
as being most effective generally considered. The longitudinal extent of the
ventilating surface, may also, according to such modifications, be made of a slightly
convex or concave formation in such applications as would render this formation of
any advantage.
By so disposing the said ventilating surfaces, in all modifications only so that
they have, and in combination with such other means as will cause or allow of
them having, the desired lateral or side action, and in other modifications by
combining ventilating surfaces thus disposed with others disposed in a cylindrical,
conical, or other analogous disposition peculiar to the said former Patent, we are
enabled to adapt this system of ventilation to any existing place, or to any aperture
of any form or shape to which such other forms would not be applicable, and could
not be well applied, without alteration or adaptation of the surface to which they
were applied.
As an example of the utility and application of the present improvements: in
applying inlet or outlet, or inlet and outlet ventilators to window frames for use in
ordinary rooms, it has hitherto been necessary in adapting the said system of
ventilation as hitherto applied to make a hole or opening in the pane or glass
or in the window frame of the size and shape of one or other part of the ventilator,
and in some modifications to construct the ventilator in two parts or in a special
manner so that it could be applied to such hole or opening: but by the present
improvements, we are enabled to adapt either inlet or outlet or inlet and outlet
ventilators to the window frame of the size and shape thereof, or of part thereof,
without requiring any alteration of the window frame, and so that they will not
interfere with the sash frames, or the operation thereof, but will or may depend for
their action partly upon the opening or closing thereof in the usual manner, as well
if desired, upon an opening part of the ventilator, instead of being independent
thereof as formerly and not under control.
as,
We in no way limit ourselves to this particular application, as the present
improvements may be adapted in various other ways and by various other
arrangements to any apartment, building, room, or other structure, place, or article
to be ventilated, and have as aforesaid more particular reference to the improved
formation and disposition of the acting ventilating surfaces, than to any particular
means of adapting the same which may obviously vary in different applications,
and with the formation of the part to be ventilated.

page_text: We, CHARLES LAWRENCE, Manufacturer, and THOMAS FITZGERALD WINTOUR,
Ventilating Engineer, c/o Messrs Day, Davies & Hunt, Patent Agents, 321, High
Holborn, in the County of Middlesex, do hereby declare the nature of our Invention
for "IMPROVEMENTS IN VENTILATING APPARATUS" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This Invention relates to improvements in ventilating apparatus and has especial
reference to certain improvements upon or in relation to the Invention described in
the Specification of Letters Patent, No 746 dated 16th February. A.D. 1882. granted
to Thomas FitzGerald Wintour, one of the present Applicants.
The object of the present Invention is to extend the Application of the principle
of action described or referred to in such Specification: and to make it more
generally applicable and serviceable to the same or other uses than described or
referred to in such Specification, in other ways and by other means applicable
otherwise than therein described.
The special object sought to be attained by the means described in such
Specification and by those improved means herein described, is to attain a perfect
system of ventilating rooms, and other enclosed apartments, buildings, articles, or
places, by a side or lateral action and exchange of the air through wire gauze or
other finely perforated surfaces which permit of a gentle and continuous exchange
of air, but prevent draught.
The acting ventilating surfaces of the ventilator (other than the plane glass or
metal ends or parts) have hitherto been disposed in a cylindrical, conical, or other
analogous manner, (excepting in, certain particular applications) and in applying
such particular formations of ventilators it often found necessary that the part to
which the ventilator is required to be applied has to be cut or otherwise made of
corresponding formation, which in some cases is objectionable, and in others cannot
well be done, and this detracts from the application and full utility of the said
Invention.
The especial object of the present improvements is to remedy such objections, in
order that the application of the principle of the said Invention may be extended as
aforesaid, and the full utility thereof attained; and so that ventilators having the
same principle of action may be constructed of other forms than described in such
Specification, and of such forms as may be required for any particular application,
and so as to avoid its being necessary to adapt the part to which the ventilator is
to be applied to the particular form of ventilator, as has as aforesaid, been hitherto
necessary.
A principal feature of the present Invention consists in the disposal of the said
perforated or equivalently formed acting ventilating surfaces in a longitudinal or
plane direction set at an inclination preferably of about 45 degrees to the surface to
which they are applied. This arrangement is however susceptible of certain
subsidiary modifications, for instance, the plane surface may be set at right angles
or at any other angle than 45 degrees as aforesaid, but the latter angle is preferred
as being most effective generally considered. The longitudinal extent, of the
ventilating surface, may also, according to such modifications, be made of a slightly
convex or concave formation in such applications as would render this formation of
any advantage.
By so disposing the said ventilating surfaces, in all modifications only so that
they have, and in combination with such other means as will cause or allow of them

page_text: having, the desired lateral or side action, and in other modifications by combining
ventilating surfaces thus disposed with others disposed in a cylindrical, conical, or
other analogous disposition peculiar to the said former Patent, we are enabled to
adapt this system of ventilation to any existing place, or to any aperture of any form
or shape to which such other forms would not be applicable, and could not be well
applied, without alteration or adaptation of the surface to which they are or were
applied.
As an example of the utility and application of the present improvements: in
applying inlet or outlet, or inlet and outlet ventilators to window frames for use in
ordinary rooms, it has hitherto been necessary in adapting the said system of
ventilation as hitherto applied to make a hole or opening in the pane or glass or in
the window frame of the size and shape of one or other or of some part of the
ventilator, and in some modifications to construct the ventilator in two parts or in a
special manner so that it could be applied or adapted to such hole or opening: but
by the present improvements (and an example of which is illustrated on the annexed
drawings and is hereinafter referred to) we are enabled to adapt either inlet or
outlet or inlet and outlet ventilators to say window frames of the size and shape
thereof, or of part thereof, without requiring any alteration of the window frame,
and so that they will not interfere with the sash frames, or the operation thereof,
but will or may depend for their action partly upon the opening or closing thereof
in the usual manner, as well as, if desired, upon an opening part of the ventilator,
instead of being independent thereof as formerly and not under control.
We in noway limit ourselves to this particular application, as the present
improvements may be adapted in various other ways and by various other
arrangements of the parts which when formed disposed and combined in the manner
herein indicated or in any substantially equivalent manner are essential and
peculiar to the present Invention, to any apartment, building, room, or other
structure, place or article to be ventilated, and it is obvious that the way in which
such parts are formed disposed and combined may vary in different applications,
and with the formation of the part to be ventilated.
The present Invention is illustrated on the accompanying drawings as applied
by way of example to an ordinary sash frame, and the improved ventilator is
represented as made of the shape and size of the upper sash frame, 1, with the
acting ventilating surfaces, 2, made of wire gauze, or finely perforated zinc or other
suitable metal or material, and set inwards and arranged in a longitudinal plane
direction at an angle of about 45 degrees to the surface of the frame to which they
are applied, and with the other essential component part of the ventilator, the part
instrumental in preventing any draughty or direct through passage of the air and
in causing or allowing of the acting ventilating surfaces having the desired lateral
or side dispersing and distributing action and consisting of the end plate or
plates, 3, made preferably of plain or ornamental glass so as to permit of and not
obstruct the passage of light either fixed or made capable of being opened at times.
The end or ends, 3, are effective in laterally deflecting the air causing it to enter or
leave the room in a lateral direction and in so doing it is dispersed by means of and
distributed through the acting ventilating surfaces, 2, which are so arranged and
combined with such deflecting part or parts, 3, as to be effective in preventing
any through draught and so as to permit only of a gentle and continuous exchange
of the air, the desiderata of most value in apparatus of the kind.
In all modifications of the present Invention there may be combined with the
ventilator an adjustable disc or means equivalent to the upper sash frame and
operated from the exterior so as to permit of the operation of the ventilator being
under perfect control.
Having now particularly described and ascertained the nature and objects of our
said Invention and in what manner the same is to be performed. we declare that
what we claim is ;-.
The combination in ventilating devices applicable for ventilating houses rooms
and enclosed apartments generally, of a part or parts 3, or equivalent means of

page_text: preventing any draughty or direct through passage of the entering or escaping air
and causing it to be laterally deflected, with acting ventilating surfaces, 2, composed
of wire gauze or other finely perforated metal or material, arranged in relation to
such deflecting parts, 3, in such a manner as to be effective in dispersing and
distributing the entering or escaping air and in causing a lateral entry or exit and
a gentle and continuous exchange thereof, when such parts are formed arranged
and combined and co-operate substantially in the manner hereinbefore described.
