PROVISIONAL SPECIFICATION.
Improvements in Ventilating Apparatus.
We EDWARD MUIR YOUNG of 10 Cathedral Close Lincoln, Architect and GEORGE
BAINBRIDGE Moss of Alton House The Close Lincoln Gentleman hereby declare
the nature of the said invention for IMPROVEMENTS IN VENTILATING APPARATUS to be
as follows:-
We construct in or in connection with domestic or other fire places one or moro
chambers bunkers or hoppers of any form as an exhaust chamber for the purpose of
exhausting foul air from rooms, halls or other buildings. We place the chamber
within the chimney Breasts, and connect it with two pipes or one pipe passing right
through the chamber. One pipe or one end of the single pipe passes up or
communicates with the chimney and the other pipe or the other end of the single
pipe passes to or communicates with a grating or gratings in the wall or walls
opening into the room, hall or other building. We raise the heat of the chamber by
contact with the fire to a high temperature, and by expelling the hot air up the
chimney shaft produce an exhaust action drawing the foul air from the room hall or
other building at a high level into the chamber and expelling it up the chimney shaft.
We face where necessary the chamber with some nonconducting material on all sides
except that exposed to the fire.

page_text: We, EDWARD MUIR YOUNG of 10 Cathedral Close, Lincoln, Architect, and GEORGE
BAINBRIDGE MOss of Alton House The Close, Lincoln, Gentleman, do hereby declare
the nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
The Invention relates to Improvements in ventilating apparatus for the purpose of
removing hot or foul air or any noxious gases from rooms halls or other buildings
and consists essentially in the construction of the apparatus hereafter described and
the combination of two or more such apparatus and its connexion with domestic or
other fireplaces or stoves or flues in the manner also described. In the Drawings
which accompany this Specification Figure 1 represents one form of the apparatus
detached, Figure 2 represents an elevation of a domestic fireplace upon which the
dotted line shows a similar apparatus in position, Figure 3 represents a plan shewing
the position of the Ventilating apparatus within the chimney Breast. In Figures 1
and 2, 6 is an air tight pipe which is connected at the top with a bend ; having an
opening fat a high level into the Room Hall or other building, and is carried down
to or nearly to or below the level of the floor and is then continued as or connected
with an inverted siphon or other bent pipe c which communicates with the bottom of
the chamber (a) here of a cylindrical form, d is a pipe connected with the lower end
of the chamber (a) next the fireplace and carried up to a point just above the
fireplace opening or the point of maximum draught in the chimney where it opens
into the Chimney at e which may be of some shape to prevent soot falling down the
pipe d, see Figure 4. When the fire is lighted the pipe d and the Chamber (a).
become heated while the pipe b remains cold; the heat of d and a and the draught of
the chimney combine to exhaust the air rapidly from d and the chamber a into the
Chimney and to draw the foul air and gases from the room at down the pipe b and
thence through c, a and d into the chimney. The carrying of the pipe c below the
surface of the floor and the interposition of the Chamber a combine to prevent the
pipe from becoming heated. This result may be assisted by surrounding the pipes b
and or the pipe c only with some non-conducting material, and the Chamber a
may be faced on all sides except that exposed to the fire with some non-conducting
material.
In some cases we adapt the invention to small fireplaces by placing the apparatus
outside the Chimney breast and prolonging the pipe d as shewn in Figure 7 so as to
pass through the chimney breast at a low level until it reaches the fireplaces when
it is continued upwards as before.-A plan of such an adaptation is shewn in
Figure 7.
In large rooms halls or other buildings where one opening ƒ may be insufficient for
the ventilation of the whole building we adapt our invention to these cases by different
methods as follows:-Wo either (A) carry a horizontal pipe g running round or
partly round the room at or below the floor line connected with the vertical pipes b
by inverted siphons or bends k as shewn in Figures 5 and 6 which are respectively
an elevation and a plan or otherwise. The pipes are carried up to a high level
inside or outside the brickwork and open into the room at f with bends ; or otherwise
or (B) we carry a horizontal pipe at a high level round the room with two or more

page_text: openings into the room and connect this with a vertical downcast pipe entering into
the bent pipe (c) and chamber (a) and thence as before or (C) we carry from
openings in the ceiling a pipe or pipes communicating with the pipe b (Figures 1. 2)
and thence as before, or (D) in the case of rooms halls or other buildings where
there may be foul heavy gases which do not rise to the top of the room (as in some
workshops and laboratories) we cut short the pipes b (Figures 5. 6) so that the
openings are at the level of such foul gases or (E) in the case of rooms halls or
other buildings which are heated by hot water or hot air apparatus we carry the
pipe or pipes (b) or (h) (Figures 1. 2. 6.) down to the basement or other level of the
furnace or furnaces for the heating apparatus and construct the pipes (b) and (d) and
the chamber (a) in connection with the furnace or furnaces.
In the case of rooms halls or other buildings heated by American or other stoves
we adapt our invention to them by connecting the pipe d with the flue or smoke pipe
of the stove.
Where the Chimney or flue has a good up draught our ventilating apparatus will
work without heat, in Summer or in Rooms where a fire is not habitually used, but
its action may be not so effective and where more effective action is required or where
in badly built chimneys there is a down draught, we adapt our invention to such
cases by the application of a gas jet or other flame placed within the chamber A for
the purpose of creating a draught through it, or by any other means such as blast fans
of an improved type or other appliances for increasing the draught which may be
applied to the pipe d or to the flue. In Summer or when no fire is used the fireplace
opening may be completely closed up to increase the draught through the Ventilator
or Ventilators. In any case the down draught in a bad chimney is effectually
prevented from communicating a backward draught through our apparatus by the
interposition of the chamber (a) which acts as a trap.
We do not confine our invention to any special form or shape of pipes or chamber
which may be respectively of any form or shape or materials and may be either
wholly or in part outside or set within or formed in the brickwork of the walls and
chimney breasts and the pipes b and the horizontal pipe g may, if necessary be carried
outside the exterior walls.
where the
For new fireplaces we prefer the arrangement shown on figures 2 and
chamber a and the pipes in immediate connection with may be set within a hollow
bunker or hopper behind the panel d there shewn, which may be a sliding or hinged
panel to enable the chamber and pipes to be examined for repairs or cleaning; or the
hollow bunker may itself be made the chamber in which case the sliding or fixed panel
must be practically air tight when closed. A door may be placed in the Chamber A
for the purposes of cleaning inspection or lighting the gas jet, if used.
Having now particularly described and ascertained the nature of our Invention and
the manner in which it is to be performed what we claim is :-
First The apparatus in connection with the Ventilation of Rooms Halls or other
buildings consisting of a cold down draught or in draught pipe or pipes and an up
draught pipe (d) attached to the fireplace, furnace stove or flue and capable of being
heated thereby and the chamber (a) and inverted siphon or other bent pipe (c)
between them as before described.
Secondly-The combination of two or more such apparatus or portions thereof in
the manner described.
