VENTILATION.
A New Invention for Heating and
Ventilating Halls, School
rooms, Dwellings. Etc.


nevertheless OF vital interest, an
anything that will tend to throw an
light on the vexed question, as it ma
be called. is of interest to every pei
son-man, woman and child. All hay
experienced the headaches, listless
ness, droWsiness and discomfort il
cident upon sitting in crowded halls
or in rooms which are very warm q
one time, and cold in the extreme a
another. If one wanted fresh air il
cold weather, cold had to be endureC
for 1t; and in order to secure prope
ventilation great expense has beer
gone to, and almost equal difficulties
endured. The question is one tina
has not alone occupied the minds o
the great public. bat the few minds
OF great scientific attainments, have
struggled to secure good venti-
latlon and at the same time maintain
the other comforts.
Some time ago, Dr.. J. r.
Park, in the Salt Lake County
Educational Association, spoke at
length on the subject of ven
tllstlon, IN the course Of which he
suggested that ventilation might be
secured In the schoolroom by placing
around the ordinary stove g sheet iron
drum, allowing a certain space be-
tween the stove and the enclosing
iron. Air could then be brought in
by pipe, or Aue, which would cor
meet with the interior OF the drum,
when the air would pass up, becom-
ing heated SIS it went up. BY being
heated 1t would become lighter and
would be distributed through the
room, while the impure air would be
forced up through the chimney, and
a constant circulation with a supply
of fresh air thus maintained.
A very short time after, the doctor
that a stove, covering the
grounds mentioned above, was being
He Immediately sent
for one for the University, and has
been using it ever since, and so COM
pletely does it cover the obstacles of
and an equal distribution
Of heat, that he heartily recommends
1t to the trustees OF all schools, and in
fact to everyone.
A visit to the University shows the
stove, or heater, to he made on the
same principal as the Franklin; that
g, it Is a stove with a CRATE in it,
and is merely for heating purposes.
Around the stove, however, is a large
ron drum. A wc01en flue, 12x4
inches, has been made, and runs
lnder the floor of the main room in
he University, and connects with the
itove underneath. A constant SUP.
1ly OF air is thus obtained, which is
carried up through the drum, and is
heated, and thus becoming volatile, or
lighter, rises and is distributed all
,ver the room. This pure warm air
presses down the foul which passes off
rom the lungs and the body, and being
naturally heavier, it keeps close to
he floor. The pressure is thus kept
Up constantly, and as there is but one
outlet for this air it passes through
he stove proLer,up the stove pipe and
nto the open ali. Thus an inces
ant circulation is kept up and fresh,
warm air is supplied in every part OF
he room, while there is not the sign
If draft. This much as a ventilator.
AS a heater it is equally efficacious.
The bad feature about stoves ia that

a fact, that the stove now

wen temperature in every part of the
DOM. 1t does not matter how large
fire may be, the drum is never SO

arthest corner. This has been |

WIEN considered. The heat does not |
adiste from the sides, but passes up

where it travels till it reaches the
ides, and there passes down, and as
will readily be seen, it is impossible
o conceive more perfect method OF
the heat Thus all the
tudents enjoy precisely like amount
# heat, like amount of fresh air,
While an even temperature can be
without any effort.
The merits Of this invention have
,een discussed by the scientific
ournsls, educational journals, and
scientific men Of the country, and is
lnhesltatingly pronounced the most
perfect ventilator apd heater ever dis
covered. Prof. E. L. Youmans,
editor of the Popular Science Monthly,
las made q thorough examination OF
he heater and from his report the
is extracted:
But what attracted me most to this
stove fireplace, was the promise Of its
capacity feature in which
ali ordinary stoves sre radically defective.
In regard TO the quality of air, close
stove-heated rooms are generally intOler-
able nuisances. AS there was no pas
sage under my floor to secure fresh air
from without l extemporized q conuec-
ton of the stove with the window,
bringing in a stream of outside air, ard
passed it through the ventilating hue of
the stove.
Though the arrangement was some
what imperfect, the effect was IN a high
degree satisfactory. The room had q
space of $3.50 cubic feet, and several
gentlemen were engaged in it at their
desks in literary work. AS soon as the
ventilating duct was put In place 9
marked improvement was felt in the air
which was greatly appreciated by tbs
occupants of the room.
1t is easy to heat an apartment. but to
warm it uniformly by an inexpensive
Continuance that secures at the same time
an abundant supply of fresh air, Is 6
desideratum that has not, ss am aware
of, been previously attained.
