Improvements in Ventilators for Buildings and other Places.
JOHN GILL 13 Common Garden Street Lancaster Metal Worker, do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to secure the more efficient ventilation of
Buildings shafts sewers soil Pipes and other Places. I accomplish my object in
the following manner I make a Base through which I pass an open shaft around
which I Place three sets of Plates or Deflectors. Leaving an open space between
each deflector, between the openings in the centre or middle set of Deflectors I
Place circular Perpendicular shafts outside of which set of Deflectors and shafts
I Place another set of deflectors. The wind Passing round Impinging against or
Passing through the outer set of Deflectors causes a vacuum in the ventilator and
a Powerful up current in the central shaft, independent of any Particular direction
of the wind a down current or snow sleet or rain being driven into the central
shaft being under my arrangement an impossibility.
It is also my intention to accomplish my object by and in addition to a series
of deflectors as before stated to Place a shaft through centre of Plate to which
upper part of deflectors are fastened, to Place a plate over or inside of shafts so
arranged as to Prevent a down draught and to Place shafts running from central
shaft to outside of head of ventilator through which the wind Passing across top
of shaft would assist deflectors in lower Part of ventilator to cause a more Powerful
up current in the shaft communicating with the interior of Building and thus
accomplish the object of my invention.
Also I make a shaft on the top of which I Place two tapering Pieces with the
broad ends fastened together and one of the narrow ends fastened to shaft over
the uppermost narrow end I Place a baffle plate the wind Passing across which
Produces an up current in the shaft and exhausts the smoke or foul air from
the flue.
Also I make a shaft on the top of which I Place Head having four openings
into the shaft down which the air current may freely Pass but which has an
internal arrangement of Plates by which any rain water entering is not allowed
to Pass through the shaft with the air current but Passes out through an aperture.
in the sides of shaft.
.It is also my intention that my invention shall take the form of an inlet
ventilator for the admission of fresh air into Buildings, by Placing three or
more deflectors across inside of inlet at varying angles by aid of which the air
current in Passing through from the outside is cut up and diffused to different
directions in the building thus mimimising the Possibility of a draught through
the air current Passing in one unbroken volume into the building.

I, JOHN GULL, of 13 Common Garden Street. Lancaster, in the County of
Lancashire, Tinsmith, 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 my invention is to secure the more efficient ventilation of buildings,
shafts, sewers, and soil pipes, and the like, I accomplish my object in the following
manner, I make a base through which I place an open shaft around which I place
three sets of plates or deflectors leaving an open space between each deflector,
between the openings in the centre or middle set of deflectors I place circular
perpendicular shafts outside of which centre set of deflectors and shafts I place
another set of deflectors; the wind passing round impinging against or passing
through the outer set of deflectors causes a vacuum in the ventilator and a powerful
up current in the central shaft, independent of any particular direction of the
wind a down current or snow, sleet, or rain being driven into the central shaft
being under my arrangement an impossibility.
It is also my intention to accomplish my object by and in addition to a series
of deflectors as above stated to place a shaft through centre of plate to which top
deflectors are fastened, to place a plate over or inside of shaft so arranged.
as to prevent a down current and to place shafts running from central
shaft. to outside of head of ventilator through which the wind passing
across top of shaft would assist deflectors in lower part of ventilator to cause a
more powerful up current in the shaft communicating with the interior of building
and thus accomplish the object of my invention.
Also I make a shaft on the top of which I place two tapering pieces with the
broad ends fastened together, with one narrow end fastened to the shaft; over
the upper end I place a baffle plate the wind passing across which produces an
up current in the shaft and exhausts the smoke or foul air from the flue.
Also I make a shaft on the top of which I place an head having four openings
into the sraft down which the air current may freely pass but which has an
arrangement of plates by which any rain entering is not allowed to pass through
the shaft with the air current but passes out through an aperture in the side of
the shaft.
It is also my intention that my invention shall take the form of an inlet
ventilator for the admission of fresh air into buildings by placing across inside of
inlet at varying angles by the aid of which the air current in passing through
from the outside is cut up and diffused to different directions in the building thus
minimising the possibility of a draught through the air current passing in one
unbroken volume into the building.
I shall now proceed to describe the same and for the purpose shall refer to
the accompanying drawings. One part of my invention relates to ventilators
where fixed deflecting plates and shafts are employed and consists in the following
arrangement which I will describe with reference to Figs. 1, amid 2, of the
annexed drawings. Fig. 3, represents a sectional plan of Fig's. 1, and 2; through
the Fig's. 1, 2 and 3, the outer circle g is the base to which upriglit deflectors are
fastened; d is the shaft communicating with the interior of building and head of
ventilator, the wind impinging against or passing through the outer circle of
deflector a is deflected by inner circle of deflectors and being unable to enter

page_text: the central shaft a suction is formed in the head of ventilator and powerful up
current is induced in the central shaft and the vitiated air rapidly drawn off
and the atmosphere in building relieved and purified.
Fig. 2, in the upper part a, b, c, and d, describes an arrangement where if
desirable an increased power of extraction may be obtained by the placing of a
number of shafts, more or less, in this case six, communicating with central shaft
in the head of ventilator. The wind impinging in any direction against head of
ventilator induces a suction in the openings a, b, c, and d, and a powerful up
current in the central shaft thus assisting the deflectors a, b, c, andid, in a more
copicus extraction of vitiated air from the building to be ventilated.
It is also my intention that my invention' (as in Fig. 4), shall take the form
of an inlet ventilator for the admission of fresh air in buildings and other places,
I make inlet in the form of a square box which may be made of cast iron or other
metal or material with a moveable front on the top of which I place an adjustable
diffusing plate also I place one or more shafts across inside of inlet, the air
entering from outside into inlet is broken by the shafts el and diffused by the
adjustable plate al into the building without any fear of draughts which might
be caused through the air entering in one unbroken volume into the building:
where desirable the shafts which may be circular or other shape may be left out
also the diffusing arrangement may be adjustable or a fixture the perforations in
same may be round or other shape.
In Fig. 5, I construct a ventilator for the efficient extraction of smoke or foul
air from chimney stacks, flues, soil pipes, and other places, g' is the shaft com-
municating with the flue or soil pipe, the wind inpinging in any direction
against the angular covers e, e, e, e, is deffected and prevented from entering the
central shaft, at the same time causing a powerful up current in the central shaft
and extracting the smoke or foul air from the place to be ventilated.
Fig. 6, represents a vertical inlet for the admission of fresh air into buildings
and other places, a is the opening through which the air current passes from
outside of building, h are deflecting plates by which the volume of air is deflected
nd broken, el is an expanding head with filtering plate for diffusing the air
current as it enters the building to be ventilated.
Fig. 7, represents a sectional plan of Figures 1 and 2 showing the deflectors
made in various forms the effect being substantially the same whether made in
ne or any of the forms as own in plans of Fig's 3, and 7.
Having thus described my invention and the manner in which the same is to
be carried out, I have to state that I do not confine myself to the exact details
herein explained as the same may be varied without altering the novelty of my
invention; they may be made of sheet zinc, iron, copper, brass, or other material,
the various deflectors or plates may be arranged in a vertical, horizontal or other
position according to the direction of the entering currents, they may be arranged
as ridge ventilators or otherwise for any special purpose to which they may be
adapted.
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 :-
1. In ventilators, the combination of the various parts as above described in this
specification and according to Fig's. 1, 2, and 3, of the accompanying drawing.
