tion is heated by extremely out-Of date
"box" wood stoves ! think that it il
safe to say that our grandfathers woulc
recognize many of the stoves now in ust
| in our schools as the same vexatious con
trivances around which they huddled or
zero mornings, gradually moving back tC
their seats as they thawed out or the
heat drove them away, only to be obliged
to return to the stove as they cooled off
this operation being repeated several
times a day. Those in the back parts OF
the room were seldom comfortable in
winter on account of the cold, while those
near the stove were unable to do good
work because of the extreme heat.
Such stoves were usually located near
the center of the room, thus taking up
the best part of the room besides being
very undesirable for the teacher, who, in
order to be near her pupils, has to en-
dure roasting all day long, thus uniting
her for her best work. Another disad-
vantage is that the stove provides no
means of ventilation. 1t simply heats
and reheats the stale and putrid air of
the school room.
If you will now carefully study the
cut which accompanies this article you
will see at figure 4, on the stove, the legs
of large round heating stove surround
ed by heatproof jacket shown at figure
2. This jacket completely surrounds the
stove and is nowhere nearer than eight
inches to the stove. You will notice that
the jacket is within about eight inches
of the floor and that the top is between
five and six feet above the floor. At fig
ure | is represented fresh air inlet
which conducts pure air from out Of
doors to the inside of the jacket. As
the air is heated it naturally rises as in.
dcated by the arrows and spreads out
over the ceiling As it gradually cools
it flows to the floor and then the coolest
and foulest air is drawn off from the
floor at figure in the foul air pipe,
which is only four inches above the floor.
The layer between four and eight inches
is drawn back through the jacket as in
dicated at on the stove. This air is
drawn back through the jacket as indi |
Gated at on the stove. This air is re-
heated thus saving in fuel and time.
At first glance it might seem that we
we're repeating the operation of the box"
stove, but if you will recall your chem
lstry and physics laws you will recollect
that carbon dioxide, one of the gases of
respiration, is heavy gas and therefor
falls to the floor together with the waste
organic matter expelled. The foul air
pipe removes this layer of poisonous air
md very little of it gets back into cir
ulation through the Jacket.
