Improvements in the Means of Admitting Air into Rooms for the
Purpose of Ventilation.
I, GEORGE BRAY, of Blackman Lane, Leeds, in the County of York, Gas
Lighting Engineer, 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 :--
This invention relates to certain improvements in the means employed for the
admission of air into rooms for the purpose of ventilation, whereby the air before its
admission into the room is deflected in any desired direction.
The means of admitting air into rooms, hitherto, are open to serious objection,
inasmuch, as the air is allowed to fall into the room so ventilated in inconvenient
positions, and down draughts are created within the area of the room usually taken
up by occupants, for the most part with this result, the inlet aperture is closed, the
heated air and vitiated atmosphere being regarded as the lesser evil of the two.
In order that my invention may be fully understood, I will describe the same by
making reference to the accompanying sheet of drawings in which
Fig. 1 represents a back view of my apparatus.
Fig. 2 a plan having the top portion removed for better illustration.
Fig. 3 a cross section through Fig. 1 and
Fig. 4 a similar view shewing the door slightly open and the apparatus placed in a
wall.
I accomplish my object in the following manner.
Into an ordinary rectangular opening formed in the wall, and passing from the
outside to the inside of the room, I place a rectangular casing A, having the baffle
plates B. C so arranged that the air on its admission through the ordinary air grate D
is carried to the bottom of the casing A; on the inside of said casing A I secure a
hinged door E, which on being closed, is by preference, flush with the face
of the wall F, on to the said door I secure a series of deflectors G placed at an
angle to the right or left with the base of the casing A as is required to direct the
current of air being admitted.
In
On slightly opening the door E, of the casing A, the current of air enters with a
force varying with the size of the opening, and the difference of temperature inside
and outside the room; by means of the bafflers B. C the air is conducted to the bottom
of the casing A. and ascends into the room at the angle of the deflectors G.
some cases it may be desirable to deflect the air against the wall nearest to the
ventilator, this is a matter of discretion, but carried into effect in all cases upon a
well defined principle that is to prevent the air falling into any area of the room in
which occupants are likely to sit or stand, and thus insure the diffusion of the
air, and the ventilating of the room, without down draughts.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
--
In combination with an ordinary apperature, a casing A with bafflers B. C.
and deflectors G secured to the hinged door E forming the complete ventilator
arranged substantially as and for the purpose hereinbefore set forth, and indicated
by the accompanying drawings.
