Wight, Gentleman, for an Invention of "IMPROVEMENTS IN VENTILATING
ADDADARIEN "
PROVISIONAL SPECIFICATION left by the said Robert Harris Reeves at
the Office of the Commissioners of Patents on the 2nd April 1881.
ROBERT HARRIS REEVES, of Parkhurst, in the Isle of Wight, Gentleman.
"IMPROVEMENTS IN VENTILATING APPARATUS."
The Invention has reference to improvements on that class of ventilating
apparatus for which Letters Patent were granted to me bearing date the 28th day
of March 1874, No. 1080.
In carrying out my present improvements I form the front plate with corru-
gations and openings through it, the sides of which taper inwards from the front
plate, so that these openings are somewhat smaller at their inner than at their
outer end.
Opposite the inner ends of these openings there are provided recessed chambers
with corrugated sides with spaces between the outer edges thereof and the inner
ends of the taper openings, as well as of the inner corrugated surface of the front
plate.
Between the back of these recessed chambers are provided other somewhat
conical or inverted bell shaped pieces with corrugated surfaces, which are applied
so as to be capable of movement in order when desired to close or regulate the
extent of the passages through the apparatus.
In use when the parts are open air passes through the apparatus by the taper
openings in the front plate, and impinging on the corrugated surface of the inside
of the recessed chambers is divided, and any damp in such air then becomes
absorbed or removed, and the air is thence conducted back between these recessed
chambers and the sides of the taper opening against the inner corrugated face of
the front plate, and by these corrugations deflected again through the passages
between the outside of these recessed chambers and the conical or inverted bell
shaped adjustable pieces, which are capable of adjustment by screw or other
suitable motion to the extent of opening for air required.

page_text: In some cases I also apply in aid of the above an inclined or conical distributer,
and in some cases the front plate or an inner plate thereto may be moveable to
close or partially close the passages.
The air in passing through this distributer is kept in about the same column or
volume, but is varied in shape in passing through the ventilator or tube between
the back and front, and in entering the room it is thrown like a spray, which
enables the air of a heavier specific gravity to mix more freely with that of a
lighter gravity inside the building.
In order to ascertain the quantity of air to be admitted a thermometer is fixed
in the distributer, and slides may be also applied to close or partly close over the
inlet to regulate the quantity of air required.
The first part or inlet of the apparatus may be made circular or of other shape
or plan, or the plates may be fixed at any angle.

"IMPROVEMENTS IN VENTILATING APPARATUS."
The Invention has reference to improvements on that class of ventilating
apparatus for which Letters Patent were granted to me bearing date the 28th day
of March 1874, No. 1080.
In carrying out my present improvements I form the front plate with corru-
gations and openings through it, the sides of which taper inwards from the front
plate, so that these openings are somewhat smaller at their inner than at their
outer end.
Opposite the inner ends of these openings there are provided recessed chambers
with corrugated sides with spaces between the outer edges thereof and the inner
ends of the taper openings, as well as of the inner corrugated surface of the front.
plate.
Between the back of these recessed chambers are provided other somewhat
conical or inverted bell shaped pieces with corrugated surfaces, which are applied
so as to be capable of movement in order when desired to close or regulate the
extent of the passages through the apparatus.
In use when the parts are open air passes through the apparatus by the taper
openings in the front plate, and impinging on the corrugated surface of the inside
of the recessed chambers is divided, and any damp in such air then becomes
absorbed or removed, and the air is thence conducted back between these recessed
chambers and the sides of the taper opening against the inner corrugated face of
the front plate, and by these corrugations deflected again through the passages
between the outside of these recessed chambers and the conical or inverted bell
shaped adjustable pieces, which are capable of adjustment, by screw or other
suitable motion to the extent of opening for air required.
In some cases I also apply in aid of the above an inclined or conical distributor,
and in some cases the front plate or an inner plate thereto may be moveable to
close or partially close the passages.
The air in passing through this distributor is kept in about the same column or
volume, but is varied in shape in passing through the ventilator or tube between
the back and front, and in entering the room it is thrown like a spray, which
enables the air of a heavier specific gravity to mix more freely with that of a
lighter gravity inside the building.
In order to ascertain the quantity of air to be admitted, a thermometer is fixed
in the distributor, and slides may be also applied to close or partly close over the
inlet to regulate the quantity of air required.
The first part or inlet of the apparatus may be made circular or of other shape
or plan, or the plates may be fixed at any angle.
But that the Invention may be the better understood, I will, by the aid of the
accompanying Drawings, proceed to describe means pursued by me in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a sectional view of parts of one portion of the apparatus ;
Figures 2 and 3 are opposite face views of the same.
In each of these views the same letters indicate corresponding parts. a, a,
represents the front plate with openings a¹, a¹, through it, and it will be observed
that these openings a' taper slightly inwards, so that the openings a' are smaller

page_text: or contracted at their inner ends than at the front or outer ends; b, b, are recessed
chambers arranged to be opposite the inner ends of these openings a¹. These
chambers b are formed with corrugated sides b¹, and there are spaces c, c, between
these chambers b and the inner ends of the taper openings a', as well as between
the inner edges of these chambers 6 and the inner corrugated surfaces of the front
plate a.
Between neighbouring recessed chambers b, b, there are provided other somewhat
conically or inverted bell shaped pieces d with corrugated surfaces d¹, and these
pieces d are applied so as to be capable of movement to and fro, as indicated by
the dotted lines d* in order when desired to close or regulate the extent of opening
of the passages through the apparatus.
This regulation may be effected by a screw e or otherwise.
In use when the parts of the apparatus are open air passes through the apparatus
by the taper openings a¹ in the front plate a, and impinging on the corrugated
surface of the inside of the chambers b is divided, and any damp in such air then
becomes absorbed or removed, and that air is thence conducted back in the spaces c
between the chambers b and the sides next thereto of the taper openings a¹ against
the inner and corrugated surfaces of the front plate a, and by these corrugations
the air is deflected again through the passages f between the outside of the
chambers b and the conical or inverted bell shaped adjustable pieces 'd.
In some cases the outer plate a or an inner plate thereto may be moveable so as
to close or regulate the flow of air as desired through the apparatus, as indicated
by the dotted lines g.
Figure 4 shows a sectional view of an arrangement of distributor for distributing
the air into an apartment as it is supplied through apparatus such as just described
or other suitable apparatus.
Figure 5 shows an internal view of the same. In this case a represents the
parts for controlling the admission of air such as described or otherwise.
The air thus supplied passes into the passage h, thence up the passage i, which
it will be seen is fan shaped to facilitate the distribution of the air supplied thereby
into the apartment to be ventilated.
Thus the air in entering the apartment to be ventilated is thrown like a spray,
which enables air of a heavier specific gravity to mix more freely with that of a
lighter gravity inside the apartment; j indicates the position of a thermometer to
indicate the temperature of the air in the apartment.
Sides may also be applied to close or partially close the passages, and thereby
regulate the quantity of air supplied.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, I weuld have it understood that I do not confine myself to the
particular shapes or other of the details shown and described, as the same may be
varied without departing from the peculiar character of my Invention.
But what I do claim is,-
First. The arranging or combining parts with corrugated surfaces forming
ventilating apparatus, substantially as described.
Secondly. I claim the arranging or combining parts forming means for dis-
tributing air in ventilating apparatus,, substantially as described in respect of
Figures 4 and 5.
In witness whereof, I, the said Robert Harris Reeves, have hereunto set
my hand and seal, this Twenty eighth day of September, One thousand
eight hundred and eighty one.
