supplied by the pure, mildly heated,
ozonized air; az no possible danger of
contamination of the heated air by the
deadly diffusible gaseous poison, carbonc
oxide (CO) (5) reduction of the tempera-
ture of the terminal gases from the boiler
by utilization of their heat to a stand
ard closely approxImating the heat of the
animal body; (6) reduction of the tenn
perature of the external walls of the
furnace by utilization of its heat to
standard closely approxlmating the heat
of the animal body.
That all of these ideal characteristics
and elements are exhibited in the
Blanchard Sanitary Perfect Combustion
House Heating System a candid. critical
inspection of the plant in operation and
on exhibition at the residence of Allan
Calhoun will demonstrate. That total or
perfect combustion of fuel supplied to
the furnace is realized repeated analysis
of terminal gases from furnaces con-
structed on the same principle conclu
sively demonstrates. Also, the fact that
given weight of fuel in this furnace
does approximately two and one-half
times the duty that the same weight will
do in the ordinary furnace is a practical
demonstration of the fact of its perfect
combustion. That an ample volume of
pure, fresh, ozonized air is supplied as
an auxiliary to the steam heat for the
purpose of ventilation, is apparent to the
observer. That the heat of the terminal
gases from the furnace before they reach
the chimney, and also the heat of the
external or radiating surface of the fur
mace is reduced to a standard closely
approximating the heat of the animal
body may also be observed That there
is no admixture of the deadly dffusble
gaseous poison, carbonic oxide, with the
air employed for heating purposes in this
invention is rendered certain from the
| fact that in the perfect combustion of
fuel this gas, which is only an unburnt
fuel gas. is burned and reduced to heat
by its reduction to carbonic acid gas
&C or.
BY happy combination in this inven-
ton of the hot air system with the steam
system of house heating, in which the
high temperature region in the furnace
is used for the generation of steam and
its low temperature region for heating
the air the hitherto insurmOuntable diff
culties in the production of an ideally
perfect sanitary system of house heating
vanish as if by magic, while at the same
time perfect results in economy in fuel
are realized. BY locating the air-heating
region in the furnace in this invention
external to the steam-heating region and
separating the two by massive, gas-im-
pervious walls, the temperature in the
former region never exceeding 300 de-
grees F., the pure, fresh, ozonized air
from the outside atmosphere can never
suffer deterioration; while at the same
time loss of heat by outward radiation is
etfectually guarded against from the
inner high Temperature region by its
! location within the low temperature
region, the massive separating walls be-
tween them serving as a copious reservoir
for heat to assist in the process of COM
bustion and to afford a surplus at night
with diminished activity in the process
of combustion. The method employed
in utilizing the heat of the terminal gases
from the steam boiler is as unique in char
acter as it is direct and practical in appli-
cation, and can only be appreciated by
witnessing the practical operation of the
! invention.
In addition to the house-heating plant
| just described, the inventor, DR.. Blanch-
ard, has achieved an equal success in the
combustion of gas, either of the natural,
fixed, heating or atmospheric variety. A
rOom-heating gas stove Of DR.. Blanch-
ards invention is now on exhibition at
the store of the firm of Calhoun & Stew
art in the village of Middlebury. Scien-
! tific tests of this stove with the best gas
stoves now on the market, | am in
formed, gives the following remarkable
results: that seven cubic feet of gas
burned in this heater give the same num-
Der of heat units in the same time that
thirty-two cubic feet give In the ordinary
gas-heating radiator! The great value
in this invention is not its phenomenal
economical results in the saving of gas,
but In the sanitary one-that 1t is per-
fectly odorless when In use, and that the
diffusible, poisonous element in gas, car
bonic oxide gas &C o., is entirely con-
sumed. This is the only gas stove in the

feet results in the combustion of gaseous
fuel. 1t Is simple In construction,
cheaply made, and is sure to supercede
all other gas stoves on the market.
The total-combustlon, coal-burning
stove to which | referred in a previous
article in the REGISTER, am Informed,
has been developed into better CONNER
cal form with attending economical re-
suits even better than the original. This
original stove is in use and on exhibition
at DIR. Blanchard's residence in the viii
lage of Middlebury, this being the Sec
Ond season of its use.
Development has also been successful
ly carried on in the Introduction of coal
and gas cooking stoves and ranges, so
