PROVISIONAL SPECIFICATION.
An Improved Outlet Ventilator.
I JOHN TAYLOR, back of 70 Haynes Street Rochdale in the County of
Lancaster, Foreman Plumber, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to construct an extractor or outlet ventilator (for
use in sheds, mills, workshops and other places) having a hood or weather guard
attached so that it can be used in all kinds of weather.
For this purpose we provide a suitable hopper-bottomed air collector fixed say to
the sloping top or bay of a weaving shed. The top of the air collector is open but
covered by a hinged flap or regulator which can be raised to any required degree,
in a hood or weather guard sloping up from the hinge towards the front thereof
which is formed with a series of fixed louvres for keeping out rain or bad weather
and preferably arranged in a curve to follow the arc struck by the flap. The
sides and top of the hood, the sides of the air collector, and also the flap are
by preference made of glass to allow free passage for the light. The free edge of
the flap is connected to a sliding rod which passes through a fixed eye so that
a cord or chain can be fixed to its other end by which the said flap can be raised to
any required angle to regulate the exit of the air from the shed.
however be adapted for adjusting this flap or regulator.

COMPLETE SPECIFICATION.
An Improved Outlet Ventilator.
I JOHN TAYLOR back of 70 Haynes Street Rochdale in the County of
Lancaster, Foreman Plumber, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to construct an extractor or outlet ventilator (for
use in sheds, mills workshops and other places) having a hood or weather guard
attached so that it can be used in all kinds of weather.
The construction of my improved ventilator will be readily understood from the
following description on reference to the annexed sheet of drawings, on which
Fig. is a sectional elevation of the same showing it placed vertically, as it
would be fixed to a window for example.
Fig. 2 is an outside front view and Fig. 3 is a plan of the air collector with the
hood and hinged cover removed.
We would here remark that it will be evident that the same can with very
slight modifications be fixed in a sloping position say to the top of the bay of a
weaving shed.
According to my invention I provide a suitable fixed hopper-bottomed air
collector a fixed vertically as shown or in a sloping position. The top a¹ of the
air collector is open but covered by a hinged flap or regulator b, which can
be raised to any required degree in a hood c or weather guard sloping up from the
hinge towards the front thereof which is formed with a series of fixed louvres c¹ for
keeping out rain or bad weather and preferably arranged in a curve as shewn to
PQ71

page_text: follow the arc struck by the flap b. The sides and top of the hood c the sides
of the air collector a and also the flap b are by preference made of glass to allow
free passage for the light. The free edge of the flap is connected to a sliding
rod d which passes through a fixed eye a² so that a cord or chain can be fixed to
its other end by which the said flap can be raised at any required angle to
regulate the exit of the air from the shed. Other means may however be adapted
for adjusting this flap or regulator b.
I also propose to apply a small stop or block (or stops or blocks) a³ of india
rubber to the top of the air collector so that if the flap is let down suddenly it
will not be liable to be broken by the shock. I also form a channel round the
sides and front of the open top a' of the air collector see Figs. 1 and 3 and to form
openings or slots ax at the front so that rain or moisture coming through and
collecting upon the flap 6 will run into the channel at a¹ and find an exit at the
openings a*. A similar channel may be formed along the inside edges and bottom
of the open back of the air collector.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The improved outlet ventilator constructed substantially as hereinbefore
described and illustrated by the annexed drawings.
Dated this 22nd day of June 1893.
