water has been practiced for a long

florists wagons is somewhat of a nov

for relieving the apparatus from air
when it is being fill I'd. 1t is filled up
to the level Of the cock, which Is then
closed. and the water on expanding
congresses the air in the expansion
pipe above it. Two 1-inch returns are
carried back from the header, drop
ping al they go toward the boiler, so
that there will be no chanca for the
lodgment Of air in them. The return
pipe drops under the boiler and an Up
ward branch from a T in it connects
with the boiler. 1t must frequently
happen that a wagon of this kind IS
left out Of doors for a consid rab!e
length Of time, when it is not in Use
and when the fire is allow>d to go out.
This, Of course in cold weather world
mean the freezing of water in the pipes
and their consequent rupture. To pre-
vent this water is drawn off through
a plug cock which has a screw thread
on the outer end, enabling a hose to
be attached to it and the apparatus
filed with water. The specially de-
signed boiler consists Of two cast-iron
boxes, both open at n eEd. The
larger box is about Is inches long II
inches high and 9 inches in width. The
smaller casting is about l inch smaller
in each dim ansion and the space be-
tween the two shells contains the wa
ter to be heated. Both are cast w tn
a slight taper 50 as to allow the pat
tern to be readily withdrawn from The
mold. 10 prevent radiation of heat
from the boiler the whole is covered
with 1 inch CT mineral wool incased in
a wood Jacket. A cast-iron front bo.ted
on to the front end of the boiler and
this is pierced FIR tire, 1-inch tubes
and a fire door. The back of the boiler
Is turned toward the front of the
wagon, and to obtain a sufficient
draught a def1ector is provided so as to
cause a current Of air to flow III ough
the hampers under the fire. The lower
part Of the def ctor turns upon a hinge
so that it may be swung out Of the way
If desired. A charcoal fire is made in
4 basket Of wire netting ard the las
ket is put in the boiler. TO insure a
mor uniform distribution of the air
as it flows through the bottom Of the
basket to the fire pipes war, int o.
duced, each n being fastened to the
front by lock nuts. The are Of such
length as to extend we'll back over the
fire so as to prevent the air from
taking a short cut on entering the fur
nae and only going through that part
of the fire that is nearest the furnace
door. Ordinarily the charcoal fire w II
last about an hour without hav ng to
be replenished. Starting with cold wa
ter, it takes about half an hour in ex-
IRENE weather to heat the a up to
such a temperature as will permit the
flowers to be carried safely.
