Improvements in or Connected with the Circulation and Distribution
of Air for Ventilating, Heating, Cooling, Drying, and like
Purposes.
We, LEVI JULIAN WING, of No. 50 Cliff Street, in the City, County and State of
New York, Manufacturer, and JEFFERSON YOUNG, of No. 51 Union Street, Boston,
Suffolk County, State of Massachusetts, Agent, United States of America, 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 improvements in Drying rooms and general heating
and ventilation, and consists in the novel features or methods of controlling and
diminishing the currents of air so as to obtain an equally distributed or measured
current of air for heating, cooling, ventilating, drying, dampening or purifying.
Figure 1. represents a vertical section of a building embracing the invention, and
Figure 2. a horizontal section of the same.
Figure 3. represents a vertical section of a room or building of another form, and
Figure 4. a horizontal section of the same.
Referring to figures 1 d 2.
The letter A. designa es a floor, and B, a ceiling, between which is arranged a
flue or reservoir C which communicates with an apartment both above and below it
or both, through openings D, which are distributed throughout the floor and ceiling
as shown in fig. 2. so that an exhaust of air is maintained in the flue or reservoir the
ensuing exhaust in the apartments is distributed over the entire area thereof thereby
producing the best possible effect. To the flue or reservoir C is connected a fan F or
other exhaust apparatus located at one end or corner of one of the rooms or
compartments and having an outlet exterior of the building provided with a door, as
at G, thereby discharging the foul air removed from the apartments at that point,
and when the building embodies a number of stories as in the example shown the fan
or its substitute is common to the flues or reservoirs of all the stories.
It is evident that the flue or reservoir C may be in one piece or may be constructed
with branches extended from the different openings of the floor and ceiling.
The openings D are of such dimensions that their total area is equal to the area of
the fan.

page_text: In the flue or reservoir C, at any suitable point or points communication with the
exterior air is afforded by means of openings M provided with sliding doors N,
which may be opened and closed at pleasure to admit or exclude the exterior air.
Near these openings are heaters, coolers or purifiers P, through which the currents of
air pass.
The air is first admitted through the openings M, and if it is desired to
pass it but once, through the rooms, the doors G and N are left open; but if the
same air is to be used again, the doors are closed, and a continuous current is kept up
through the rooms and the flue or reservoir C, as indicated by the arrows, or the
door & may be opened so as to allow a portion of the air to escape to the exterior,
when it becomes foul or overheated.
If desired the return portion of the flue, designated as ( may be omitted when the
apparatus is used only for for ordinary ventilation and heating.
Referring to Figures 3 & 4.
The letters A, B, designate two or more rooms or apartments divided from each
other by means of a vertical partition C and communicating with each other at each
end of said partition through an opening D. In said partition is an additional
opening E provided with doors E¹, and in the side walls of each of the rooms A, B,
are openings E also provided with doors F', which in turn are provided with sliding
panels G, of glass through which the goods can be seen and a thermometer read
without opening the door or panel thereby giving exact condition and temperature of
the room, the openings in said walls being approximately opposite to the openings in
the partition.
At or near one end of the room A, is a heater, cooler or purifier H, composed in
this example of steam pipes and at or near the corresponding end of the room D is an
exhaust fan I.
At the end of the room B opposite the fan is a screen J, constructed in this case of
vertical slats arranged in V shape, or forming two sides of a triangle, and can be
opened or closed so as to fill width of room or not; and in the reservoir A, near the
heater E, is a similar screen J2. The slats have spaces between them. The united
area of said spaces between the slats being equal to the area of the disc fan thereby
not only forming division in the air of the rooms, but supplying a gauge of the .air
as well, and by arranging the screen in the tapering or V shaped form, it serves as a
spreading and equalizing device. The heater H extends to a point near the top of
the room A and to said top is hung a deflector K to rest upon the heater, additional
deflectors I. being also suspended to said top or other parts of the rooms at divers
points. These deflectors are hinged to ceiling and can be raised or lowered to suit
conditions or when getting goods or stacks of glue &c. in or out.
The goods to be treated, as dried or acted upon are introduced into the room B
through the proper doors and are generally shifted along in said room so as to become
exposed to a current of air produced by the operation of the exhaust fan, of gradually
increasing temperature, or the goods may be transferred from one room to another
through the opening of the partition. Fresh air may be admitted to the room A, and
discharged from the room B. by opening the panels of the proper side door the
panels permitting the amount of air admitted or discharged to be regulated and if
desirable the air that has once passed through the goods may be repassed through the
heater by opening the end doors D' of the partitions, this door being at a point
intermediate of the heater H and fan I. The heater H may be divided into sections
each adapted to be supplied with the proper heating medium independently of the
other and the effect of the deflector K, resting upon the heater is to cause every
portion of the air to pass through the heater, whilst the effect of the auxiliary deflector
or deflectors L is to throw the circulating air downward from the ceiling upon
the goods.
The effect of the screen J and J' is to divide the air passing between the slats of
which they are composed into either vertical or horizontal columns and by this means
more uniformly distribute the air. By this arrangement of the doors E, F of the
partition and side walls convenient access is afforded to the doors of the partition
through the doors of the walls,

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we
claim is,
1. In a building, drying or cooling room, an open partition or series of openings in
floors and ceilings reaching across the room, when the area of all the openings
shall be equal to the area of the fan or other moving power, substantially as herein
described.
2. In a building cooling or drying room, the combination of an open partition for
gauging the quantity of air, with a fan or other power for steam heater purifier or
cooler, substantially as herein described.
3. In a building, drying room or chilling room, a spreading or measuring partition,
or opening in floors and ceilings of area about the same as area of the fan in
combination with a fan or other power for moving air and heating, cooling and
purifying apparatus, substantially as herein described.
4. In drying, cooling, heating or purifying rooms, the deflectors K, L, for keeping
the current of air through the heater purifying or cooling, substantially as herein
described.
5. In a drying, cooling, heating or purifying apparatus, the doors or slides,
arranged as shown and described for admitting giving quantities of fresh or new
air, and for forcing out the cooled, heated or impure air substantially as described.
6. In a building, the reservoir or duct between floor and ceiling, the openings in
floor and ceiling of an area equal to fan, the return flue and doors, or slides for
changing the air in combination with a heating, cooling or purifying apparatus
substantially as herein described.
7. In a ventilating apparatus for buildings the combination of a flue or reservoir
arranged between the floor and ceiling to communicate with an apartment both
above and below it through openings which are distributed throughout the floor and
ceiling, with a fan or other exhaust apparatus to the flue or reservoir having an
outlet exterior of the building as set forth.
