AN IMPROVED CONSTRUCTION OF VENTILATOR
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, RICHARD ALFRED GOODMAN of 1, Commercial Street, Halifax, Yorkshire,
Engineer do hereby declare the nature of my invention for "AN IMPROVED
CONSTRUCTION OF VENTILATOR" to be as follows:-
•
This invention has reference to that description of ventilator employed in
ventilating rooms through the roof of a building, consisting of a vertical stationary
tube, having a horizontal tube on the top thereof and capable of rotating upon a
spindle according to direction of wind.
My improved ventilator consists in the employment of a stationary vertical
tube, the lower end of which is in communication with the room intended to
ventilated.
-
Within this tube are suitable stays or brackets, for supporting a vertical spindle
on the top of which spindle I attach a cone shaped tube placed horizontally, but
having a short vertical branch pipe projecting therefrom so as to cover the upper
end of the stationary tube, which is surrounded by an annular ring filled with oil;
mercury, or water so as to prevent any air from outside entering the junction of
the stationary and rotary pipes. Within the cone shaped tube I place another
cone, the largest end of which is equal in diameter, or larger if necessary to the
largest end of the outer cone, and is connected thereto by solder or otherwise.
The smaller end of the inner cone is some distance off the end of the outer conc, so
that when the wind blows into the larger end of the cones, a partial vacuum is
formed within the outer cone, which immediately draws the foul air up the vertical
tube, thereby removing impurities from the room and creating a circullation of air
without making any down-draught.
As the vertical spindle is free to rotate the cones on the top thereof are blown
around by the wind, causing a constant circulation of air; the double cones making
a sure and effective ventilator.
As the up-draught depends upon the quantity of air passing through the
horizontal cone; there is not much circulation of air in calm weather; to meet this
difficulty I introduce a pipe up the ventilator having its outlet end in the conc
steam or compressed air admitted therefrom will cause updraught and circulation
to any required degree.

COMPLETE SPECIFICATION.
I, RICHARD ALFRED GOODMAN of 1 Commercial Street, Halifax, Yorkshire
Engineer, do hereby declare the nature of my invention for "AN IMPROVED
CONSTRUCTION OF VENTILATOR" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
This invention has reference to that description of ventilator employed in
ventilating rooms through the roof of a building, consisting of a vertical stationary
tube having a horizontal tube on the top thereof and capable of rotating upon a
spindle according to direction of wind.
My improved ventilator consists in the employment of a stationary vertical
tube, the lower end of which is in communication with the room to be ventilated.
Within this tube, are suitable stays or brackets for supporting a vertical spindle
capable of rotating, on the top of which spindle I attach a tube placed horizontally,
but having a short vertical branch-pipe projecting therefrom; so as to cover the
upper end of the stationary tube which is surrounded by an annular ring filled
with oil, mercury, or water, so as to prevent any air from outside entering the
junction of the stationary and rotary pipes:
Within the horizontal tube I place a cone-shaped tube, the largest end of which
is equal in diameter or larger if necessary to the open end of the outer tube, and is
connected thereto by solder or otherwise. The smaller end of the cone is some
distance off the end of the outer tube so that when the wind blows into the larger
end of the cone, a partial vacuum is formed within the outer cone, consequently
the foul air is drawn up the vertical tube, thereby removing impurities from the
room and creating a circulation of air without making any downward draught.
In order that my invention may be more fully understood, I herein give reference
to the accompanying sheet of Drawings wherein Fig 1 is elevation of a ventilator
constructed according to my invention. A is the stationary vertical tube, the
lower end of which is placed on the top of a building and in communication with
the room to be ventilated. Above the tube A is a horizontal rotary tube B
having one end thereof turned or bent down to a vertical position, and covering
the upper end of the tube A, which is surrounded by an annular ring or channel a
filled with oil, mercury, or water, so as to prevent the air from outside entering
between the junction of the stationary and rotary tubes. The tube B is attached
to and revolves with the central vertical spindle D, which is attached to such tube
by means of the stay or bracket F, the lower end thereof being supported by a
short pipe G provided with a cup b for lubricating the foot of the spindle. Within
the horizontal tube B and attached thereto. is a cone H the largest end of which is
equal in diameter, or may be larger if necessary than the opposite end I of the
outer tube, such large end of the cone facing the wind by means of the vane or
arrow J. The smaller end of the cone is some distance off the end of the tube B
as shewn in the Drawings, so that when the wind blows through the cone, a
partial vacuum is formed within the outer chamber, thereby drawing the foul air
up the vertical tube A, consequently removing impurities from the room, at the
same time creating a constant circulation of air therein without making any

page_text: downward draught. An annular opening c is made in the horizontal rotary tube B
to assist the foul air out of the ventilator.
As the upward draught depends upon the quantity of air passing through the
horizontal tube, it is evident that in calm weather, the atmospheric air will be
insufficient to cause the necessary up-draught; I therefore arrange that steam or
compressed air may be blown through the tube B somewhat as shewn in Fig 2,
which is sectional elevation of the ventilator with certain additions for creating air.
M is a steam pipe employed to convey steam from a boiler to the chamber N in
which rests the foot of a vertical steam pipe L having perforations therein, such
pipe being supported by the gland or stuffing box K the use of which will be well
understood.
As steam enters the pipe L through the perforations, it passes up the said pipe
and is eventually blown out at the contracted end or jet d thereby causing
circulation to any required degree.
The vertical spindle as shewn in Fig 1 may be so arranged that when the use of
steam or compressed air is required a jet d and steam pipe L can easily be fixed
thereto, or vice versa.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
Firstly. The use and employment of the cone shaped tube H in combination
with the horizontal rotary tube B for purposes substantially as shewn and
described.
Secondly. The employment of apparatus as shewn in Fig 2 for injecting steam
or compressed air into the cone H for purposes substantially as described.
