Improvements in Revolving Chimney Cowls and Ventilators for
Exhaust and for Transmitting Ourrents of Air into Buildings.
CHARLES GLANVILLE, Sanitary Engineer and WILLIAM RICHARD WILLIAMSON
Sheet Metal Worker of 5 Young Street High Street, Kensington, W. in the County
of Middlesex, do hereby declare the nature of this invention to be as follows :-
This invention consists of a Cylinder or Drum divided into any number of equal
parts as, 3, 4, 5, or 6.
The proportion of cylinder is that radius shall equal depth.
The dividing of the Cylinder is described as follows:
The circumference is divided into the required number of divisions. From each
point in the circumference, a vertical line is drawn, which divides the Cylinder into
the same number of parts as the circumference of the base or plan is divided and from
the top of each of these points to the next point in the base to the right, a line is
drawn which forms the Cylinder into the same number of right-angled triangles as
there are divisions of the Cylinder.
The diagonals of these triangles are joined by another triangular piece of metal
which terminates at the centre on the base, leaving an opening below, and also an
opening on the vertical line of the outward triangles, thus forming hollow wedge-
shaped Fans
By rotating the Fans thus formed a spiral current upward is generated in the tube
or shaft and the smoke or air is forced through the Fans, and is egected to the right.
If these Fans were working in a closed Cylinder or tube the smoke or air would be
drawn up, and egected inside the Cylinder or tube in which the Fans are placed, so
in order that the exhausted air or smoke shall be dispersed an opening is made in the
Cylinder the same depth as the Fans, and the smoke or air can then get away, and in
order to prevent the wind counter-acting the action of the Fans, a suitable weathering
is provided and is explained as follows.
In the opening in the Cylinder where the Fans are placed three or four frustrums
of Cones are fixed together so that they weather each other, and are made of sufficient
size that the areas of the concentric spaces together are greater than the area of the
tube or shaft in which the Fans are placed, and the smoke or air is at once dispersed.
By reversing the action of the Fans a downward current is caused and can be
used as an Injector of air into Buildings, and for ventilating soil pipes &c.
The shape of Inlets for conveying air into the Fans for transmission down a pipe or
shaft is explained as follows.
A number of apertures are cut in the Cylinder or tube in which the Fans are placed
and these apertures are formed into chambers outside, open to the right and sealed to
the left or vice versa, so that each chamber has an Inlet to the Fans from outside, and
the outlet would be the end of the pipe or tube.
When the Fans are for Exhaust the vertical line or opening of each Fan is to the
right, and when used as an Injector they are to the left.
It is also to be stated that the Fans can be used both vertically and horizontally.
A spindle is fixed to the centre of the Fans, and connected to outside wind fans,
suitable to revolve the Internal Fans.
The top of the Cowl is constructed so that it can be detached for the purposes
of oiling and adjustment.

Figure 1 is a vertical central section showing one form of our improved cowl

Figure 2 is a horizontal section on the line x, x Figure 1.
Figure 3 is a front elevation showing the arrangement we prefer to employ when
the apparatus is designed for forcing air into a room or the like.
Figure 4 is a horizontal section on the line y, y Figure. 3.
Like letters indicate corresponding parts throughout the drawings.
A is the casing of the cowl or hood the lower part of which is adapted to be secured
in the top of the chimney or in any other suitable aperture, and the upper part of
which is provided with louvres B for permitting the escape of the smoke, waste
products of combustion or foul air therefrom.
In the casing A we provide a cross-piece a having a suitable footstep bearing b in
which is supported the lower extremity of a vertical shaft or spindle c.
Upon the
shaft or spindle c is keyed or otherwise secured an exhaust-fan d the arms or blades
of which are constructed with helical parts for drawing or forcing the air or waste
products of combustion in the desired direction and with a shield, guard or casing
formed in one or more parts as shown in the drawing. The said shaft or spindle
extends a considerable distance upwards and is supported at its upper extremity
in a suitable adjustable bearing e. A top or cap A provided with a spike or other
ornament is connected to the casing A by means of rods or bars f. 9, g are arins
or blades the extremities of which are secured to plates or drums h firmly attached
in any suitable manner to the spindle c. The lower plate or drum h forms a baffle
plate or deflector which deflects the smoke, waste products of combustion or foul
air drawn upwards by the exhaust-fan d, and causes the same to pass out through
the louvres B.
We prefer to provide the bearings 6 and e with hardened steel spheres or balls i
fitting into suitable sockets or recesses provided in the extremities of the shaft or
spindle c and in. the bearings band e. The said bearings and spindle are also
preferably constructed of hardened steel. j, j are oil boxes or cups which surround
the said bearings and serve to keep the latter free from dust, dirt or other foreign
bodies and to contain oil or other lubricant. k, kare pipes or tubes for convenience
of filling the said oil boxes or cups. is a shield or guard secured upon the
spindle to more effectually prevent the entrance of dust or dirt into the lower

page_text: bearing b, is an oil hole through which the lubricant contained in the lower oil-
box or cup has access to the socket in the lower extremity of the shaft. or
spindle c.
The spike or other ornament upon the top or cap A¹ is made removable so that
access can be had to the upper oil tube k, and to the bearing e for purposes
of adjustment and lubrication. When the said spike is in position the lower
portion thereof which is recessed to receive the head of the adjustable bearing e
and the extremity of the oil tube k, forms a weather guard for protecting the said
bearing and vil tube. m, m are bayonet and socket joints for retaining the said
spike in position.
The operation of the apparatus is as follows, that is to say:-The wind or
currents of air acting upon the arms or blades g of the motor cause the latter
and consequently the exhaust fan d to rotate more or less rapidly. The said arms
or blades 9 are so arranged that the said exhaust fan will be rotated in the proper
direction to create a powerful suction and thus effectually draw upwards, or exhaust
the smoke or waste products of combustion from the chimney, or the foul air
from the room or the like with which the said apparatus is connected, and expel
the same through the louvres B.
By altering the position of the arms or blades g so that the motor and exhaust-
fan will be caused to rotate in the reverse direction, the said fan may be utilized
as a blower for forcing fresh air into a room or the like for ventilating or other
purposes. The same result may obviously be obtained by reversing the position
of the fan-blades. In some instances we invert the blades d, that is to say, we place
the end for end upon the shaft or spindle c.
Figures 3 and 4 illustrate a modification of our invention in which the fan is
arranged as a blower, and is intended to be employed for forcing fresh air into a room
or other place for ventilating purposes. In this case the position of the blades & is
reversed so that when they are caused to rotate by the wind motor g they will act so
as to draw or suck in air from the exterior in a similar manner to an ordinary blower
and force it down the ventilating shaft. The louvres B are moreover dispensed with
and the casing A is provided with projections A³ the lower parts of which are open so
as to permit the air to have free access to the said fan or blower d.
According to another modification of our invention we employ a fan or blower
having blades substantially similar in construction to those hereinbefore described, but
inverted or placed end for end upon its shaft or spindle. In this case we prefer to
employ a wind motor in which suitable arms or blades are provided upon a drum
placed upon the outside of and secured to the said fan and by means of which it may
be rotated by the currents of air, in one or in the other direction so as to form either
an exhaust fan or blower as desired. The smoke or foul air drawn upwards or the blast
of air induced in this case, by the said exhaust fan or blower passes upwards or down-
wards through the latter as the case may be and is withdrawn from or delivered into
the room or other place which it is desired to ventilate, by means of a suitable pipe.
This arrangement is especially advantageous for ventilating purposes.
It is obvious that we can somewhat modify the construction of our apparatus
without departing from the nature of our said invention.
For example we can arrange the exhaust fan or blower horizontally instead of
vertically as herein before described, and provide suitable mitre or bevel wheels for
communicating motion from the shaft or spindle of the wind motor to the shaft or
spindle of the said exhaust fan or blower.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we wish it understood that we
claim :-
First. In a ventilating or other cowl or hood, the combination of the wind-motor
with the exhaust-fan or blower, substantially as, and for the purposes, set forth.
Second. A ventilating or other cowl or hood wherein an exhaust-fan or blower
and a wind-motor are mounted upon a shaft or spindle supported in ball or other

page_text: suitable bearings, one of which is adjustable, substantially as, and for the purposes, set
forth.
Third. The improved exhaust-fan or blower for use in combination with a wind-
motor for ventilating and other purposes, substantially as illustrated and described.
Fourth. In a ventilating or other cowl or hood, the combination, with a casing
having louvres, of an exhaust-fan and a wind-motor the lower portion of which forms
a baffle-plate or deflector for causing the smoke or foul air drawn upwards or exhausted
by the said fan to be deflected and pass out through the said louvres, substantially as
described.
Fifth. The modification of our invention wherein the exhaust-fan or blower is placed
horizontally and motion is imparted thereto from the wind-motor by means of bevel-
gearing, substantially as described.
Sixth. The modification of our invention wherein the wind-motor is placed upon a
drum provided upon the exterior of the exhaust-fan or blower and the smoke or foul
air passes up through the latter, substantially as described.
Seventh. The improved cowl or hood constructed substantially as described with
reference to Figures 1 and 2 or to Figures 3 and 4 of the accompanying drawings
and operating as, and for the purposes, above specified.
