Improvements in Means for Ventilating Houses, Shops, and the like.
I, HARGREAVES GREEN, of Moss Side Farm, Milnrow, near Rochdale, in the
County of Lancaster, Farmer, do hereby deolare the nature of this invention
to be as follows:
The object of this invention is to provide simple means for circulating fresh
air in the interiors of houses, shops or the like and enabling the foul or vitiated
air to be easily and simply removed, and thus enable the rooms to be more healthy
for their inhabitants.
In carrying out my invention and referring more particularly to the ventila-
tion of a house I preferably provide in the ceiling of the room or rooms-say in
the ceiling of the front or living room-a perforated grid of a suitable character,
the holes in which communicate with the underdrawing, or space between the
ceiling and the floor above.
or
Above the grid I provide a suitable closed passage or conduit, the said passage,
in some cases, being composed of two of the floor beams, or of a separate tube
specially made for the purpose. This passage may be arranged to communicate
with a vertical tube running up the side wall of the building
at any other convenient place. The vertical tube may proceed upward
direct to the highest point in the roof of the house or discharge into
a bell-shaped chamber or hopper fixed to the roof and communicating with the
outside atmosphere. Means may be provided to prevent any down draught or the
entrance of rain etc. All the rooms of the house may be provided with similar
horizontal tubes or air chambers in the under drawing and each tube may be
provided with a perforated grid and may also communicate with the vertical tube
running up to the roof.
Instead of the horizontal channels discharging into a vertical tube as described
they may be led into a flue. Further I may provide means such as doors or shutters
in the channels at any convenient place so that I may close the air passage, if
desired.
In some cases I may place a grid in one of the outer walls of each room or
rooms and carry the air therefrom to any convenient part of the room by means
of a tube or the like. I may also carry air from beneath the staircase by means
of a tube and place a grid in the staircase controlled by a shutter or the like..
From the foregoing description it will be readily understood that the foul air
passes through the perforated grids and into the channels, from whence it is led
into the vertical tube or pipe and so out through the roof.
I may arrange the channels and tubes in any convenient manner and so that
if desired the air of one room may be passed into another room.

I, HARGREAVES GREEN, of Moss Side Farm, Milnrow, near Rochdale, in the
County of Lancaster, Farmer, 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 provide simple means for circulating fresh
air in the interior of houses, shops or the like and enabling the foul or vitiated
air to be easily and simply removed, and thus enable the rooms to be more healthy
for their inhabitants.
The invention will be thoroughly understood from the cecompanying drawing
which shows the application of the impvements to a house, though it will b
understood that the invention is applicable to shops or other buildings or the like.
In carrying out my invention and referring more particularly to the ventilation
of a house I preferably provide in the ceiling of each room or rooms at a con-
venient and suitable poin, a perforated grid A, of a suitable character, such as
perforated zine or wire cauze, the holes in which communicate with the under-
drawing B, or space between the ceiling and the floor above. Above each grid A,
I provide a suitable closed passage or conduit C. the said passage, in some cases,
being composed of the space between two of the floor beams, or of a separate tube
specially made for the purpose. This passage C, may be arranged to communicate
with a vertical tube D, running up alongside one of the walls of the building or
at any other convenient place. I preferably make the tube D, narrower towards
its upper end so as to have a greater influence on the air. The vertical tube may
proceed upward direct to the highest point in the roof of the house or discharge
into a bell-shaped hopper E, fixed to the roof and communicating with the outside
atmosphere. Means such as a cowl F, of any suitable form may be provided to
prevent any down draught or the entrance of rain etc. All the rooms of the house
may be provided with similiar horizontal tubes or air chambers in the underdraw-
ing and each tube may be provided with a perforated grid and may also com-
municate with the vertical tube running up to the roof as shown in the drawing.
Instead of the horizontal channels discharging into a vertical tube common to
all the channels as described they may be led into a flue, or the tube D, may com-
municate with a flue near its upper end. In order that I may have full control
over the amount of air passing through the channels and so enable me to regulate
or entirely shut off, if required, the channels C from the source of supply I provide
means such as hinged doors or sliding shutters D¹ in the channels at any con-
venient place but preferably immediately over the grids A. These doors can be
raised and lowered at will by means of cords H passing over pulleys J as will
be understood.
In order to allow of the ingress of fresh air to the rooms to drive out the foul
or vitiated air through the grids A I place one, or more grids or perforated tiles A¹
in a suitable position in one of the outer walls of each room or rooms as in the
lower rooms shown in the drawing. In some cases I carry the air therefrom to any
convenient part of the room by means of a tube or the like as in the upper rooms
or bedrooms shown in the drawings. In the latter case I may form the tubes in
several different ways. In the bedroom at the right hand side of the drawing I
fix across one of the corners of the room a board or the like K behind which the
incoming air can flow upwards to a branch channel or conduit formed of a board L
placed across the upper corners of the room. This board may extend all round
the room, if desired, or only partially so, and is perforated in such a way as to
allow the fresh air to escape therethrough into the room and drive out the foul air

page_text: through the grid A and thence along the channels or conduits C to the vertical
tube D and so out at the roof as already explained. In the bedroom at the left
hand side of the drawing I have shown the air inlet tube M formed of sheet metal
to the section shown. It will however, be understood that the shape of this may
be varied to suit requirements the main object being to efficiently and evenly con-
vey air through the tube to the top of the room. I may, of course convey the air
round the room partly between the floor boarding and the ceiling, using a per-
forated plate or the like for its egress into the room. such plate being fixed flush
with the ceiling. I may also carry air from beneath the staircase by means of
a tube and place a grid in the staircase controlled by a shutter or the like.
From the foregoing description it will be readily understood that the foul air
passes through the perforated grids and into the channels, from whence it is led
into the vertical tube or pipe and so out through the roof.
I may arrange the channels and tubes in any convenient manner and so that if
desired the air of one room may be passed into another room.
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:-
The improved means for ventilating houses, shops, other buildings and the like
constructed and arranged substantially in the manner described and as shown in
the accompanying drawings.
