Improvements in Apparatus for Enforcing Air Currents for
Chimneys, Ventilation, and the like.
I FLORENCE HONOUR LANGWORTHY, of Geys House, Holyport, in the County
of Berkshire, Gentlewoman, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the construction of apparatus which is actuated by
exposure to the wind; and has for its object the displacement of smoke in
chimneys, and the like, or the substitution of pure air for foul.
I construct my invention of metal, and as an apparatus for the displacement of
smoke, or fumes in chimneys; I form from sheet zinc, or other metal, three short
tubes or cylinders; the end of one tube,. which I shall hereinafter refer to as the
perpendicular tube, I secure near the middle and at right angles to a second tube,
which I shall hereinafter refer to as the horizontal tube, and I form at the connection
a full aperture or opening between the two tubes; one end of the third tube,
which I shall hereinafter refer to as the stationary tube, I insert perpendicularly,
and loosely within the end of the perpendicular tube; and I connect the horizontal
and perpendicular tubes to the stationary tube, by suspending them upon a centre
pointed rod, the base of which I secure centrally and perpendicularly within the
stationary tube. That the horizontal and perpendicular tubes, may pivot over
the stationary tube with a minimum amount of friction, I form a bridge over the
aperture of the perpendicular tube, to which I affix centrally a narrow tube. In
the upper part of said narrow tube I secure a centre plate, to receive the centre
point of the rod; and within the lower part of the narrow tube, I secure a washer
shaped ring to prevent side-cant. At one end of the horizontal tube I form of
sheet zinc, or other metal, an internal cone-shaped funnel, having an aperture or
opening at its point end, over which, I secure the end of a tube, (small in diametre)
which I shall hereinafter refer to as the ventiduct tube, and I extend the ventiduct
tube within the diametrical line of the horizontal tube, a short distance over the
aperture of the perpendicular tube. To the upper side of the opposite end of
the horizontal tube, I secure perpendicularly, a vane-plate, and I balance the ends
of the horizontal tube, that it may pivot evenly upon the centre-point of the rod.
Thus, if the lower end of the stationary tube is secured perpendicularly over
the top of a house chimney, the wind would strike the vane-plate, and cause
the horizontal tube to pivot, until its internally funnelled end opposes, or heads the
wind; which would be gathered, or collected, and then pass along the ventiduct
tube with concentrated force, and so carry out any accumulated smoke in the
opposite open end of the horizontal tube, and further; create an enforced and
continous displacement of smoke, or foul air within the perpendicular tube.
Otherwise, a partial vacuum would be produced.
In the modification of my invention as a ventilator, where a supply of pure air
is required, I elbow the ventiduct tube centrally down the perpendicular tube, and
employ its interior for the reception of the centre pointed rod, and I also perforate
the ring, and centre-plate, for the free passage of the pure air, reserving by means
of a small horizontal ventiduct tube within the main horizontal tube, a small
quantity of wind to expel the foul air.

FLORENCE HONOUR LANGWORTHY Geys House, Holyport, Berks, Gentle-
woman, 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:-
My invention relates to the construction of apparatus which is actuated by
exposure to the wind, and has for its object the displacement of smoke in chimneys,
and the like, or the substitution of pure air for foul.
I construct my invention of metal, and as an apparatus for the displacement of
smoke, or fumes in chimneys, I form from sheet zinc or other metal three short
tubes or cylinders. The end of one tube which I shall hereinafter refer to as the
perpendicular tube, I secure near the middle and at right angles to the outside of
a second tube, which I shall hereinafter refer to as the horizontal tube, and I form
at the connection a full aperture or opening between the two tubes. One end of
the third tube which I shall hereinafter refer to as the stationery tube, I insert
perpendicularly and loosely within the end of the perpendicular tube, and I connect
the horizontal and perpendicular tubes to the stationery tube, by suspending them
upon a centre pointed rod, the base of which I secure centrally and perpendicularly
within the stationery tube. That the horizontal and perpendicular tubes may
pivot over the stationery tube with a minimum amount of friction, I form a bridge
over the aperture of the perpendicular tube, to which I affix centraly a narrow
tube. In the upper part of said narrow tube I secure a centre plate, to receive
the centre point of the rod, and within the lower part of the narrow tube I secure
a washer shaped ring, to prevent side-cant. At one end of the horizontal tube
I form of sheet zinc or other metal, an internal cone-shaped funnel, having an
aperture or opening at its point end, over which, I secure the end of a tube small
in diametre, which I shall hereinafter refer to as the ventiduet tube, and I extend
the ventiduct tube within the diametrical line of the horizontal tube a short
distance over the aperture of the perpendicular tube. To the upper side of the
opposite end of the horizontal tube, I secure (perpendicularly) a vane-plate, and
I balance the ends of the horizontal tube that it may pivot evenly and truly upon
the centre point of the rod.
Thus if the lower end of the stationery tube is secured perpendicularly over the
top of a house chimney, the wind would strike the vane-plate, and cause the
horizontal tube to pivot until its internally funnelled end faced the direction of
the wind, when the wind would be gathered or collected, and then pass along the
rentiduct tube with concentrated force, and so carry out any accumulated smoke
in the opposite open end of the horizontal tube, and further, create an enforced, and
continous displacement of smoke or foul air within the perpendicular tube.
Otherwise a partial vacuum would be produced.
In the modification of my invention as a ventilator where a supply of pure air is
required, I elbow the ventiduct tube centraly down the perpendicular tube, and
employ its interior for the reception of the centre pointed rod, and perforate the
ring and centre-plate for the free passage of the pure air, reserving by means of a
small horizontal ventiduct tube within the main horizontal tube, a small quantity
of wind to expel the foul air.
To further illustrate my invention 1 will now refer to the annexed sheet of
drawings.
Figs. 1, & 2, show a side and front view of my invention for the displacement
of smoke or foul air, or as a cure for smoky chimneys. The parts marked A,
show the horizontal and perpendicular cylinder connection, which pivots upon the

page_text: centre pointed rod marked b, the base of which is secured within the stationery
cylinder marked c. The part marked d. shows the cone shaped funnel to which is
secured the ventiduct tube marked e, and supported by the bridge marked f. To
the bridge is secured the tube marked g, in which the centre-plate marked his
secured. The vane-plate is marked i, and the arrows in the funnel, ventiduct tube,
and horizontal cylinder, shows the direction of the air current which causes the
smoke or foul air, to rise in the direction shown by the arrows in the stationery,
and perpendicular cylinders.
Figs. 3. & 4. show a side and front view of my invention as a ventilator. The
parts marked A, show the horizontal and perpendicular cylinders which rotate in
a similar manner to Figs. 1. & 2, by pivoting upon the centre pointed rod marked b,
the base of which is secured within the inner tube marked C¹. This inner tube is
secured by brackets within the stationery cylinder marked C. In this modification of
my invention I elbow the ventiduct tube marked e, within the end of the tube
marked C. The part marked e', shows a small ventiduet tube for the purpose of
enforcing a current, and expelling the foul air. 1 cover the connection between
the perpendicular, & stationery cylinders, by attaching a peice of wash leather
marked d, or other soft material to the end of the perpendicular cylinder.
part marked, shows the collecting funnel, which is kept face to the wind by the
vane-plate marked 9. The arrows indicate the course taken by the pure air down
the central ventiduct tube, and the arrows around the outside of the ventiduct tube,
the course taken by the expelled foul air.
The
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The construction of apparatus for enforcing air currents for chimneys, and
ventilation, as herein particularly described and specified.
2. The construction of ventiduct tubes in the manner, and for the purposes as
herein described and specified.
