Do you have a number of radia-.
tors in your house which seem to
be particularly difficult to heat?
If your heating system happens to
be Of the one-pipe steam variety
with some kind of automatic firing
like oil or gas. there is a good pos
sibility that your trouble lies in
the improper venting of the radia-
tors. It's pretty delicate job to
balance system of that type using
ordinary adjustable air wales and,
as you no doubt know. unless this
air is removed rapidly heat will not
be delivered to places where it is
needed most
To provide the closest possible
adjustment of the venting speed of
each radiator new precision air
valve has recently been introduced
which is equipped with a microme-
ter dial-adjusting device. This deal
is chrome plated and numbered
with 10 different venting speeds
which are spaced SO that they repre-
sent a change of so per cent higher
or lower with each number. On
top of the dial is a crescent shaped
slot which shows you at once lust
how far open or closed that par
tlcular valve happens to be. This
dial is also arranged in such a way
that the various venting speeds
are spaced like spread-band tun-
ing dial' on a modern radio. Thus,
the various speeds are distributed
around the dial and not jammed
up at either end.
Kissing Eliminated.
You will not be troubled with
the old-fashioned kissing which
went on when air was being elected
from the radiator, because these
new air valves are equipped with
special drainage Arrangement
which creates a centrifugal action
between the water and air inside
and thus prevents water from reach
ing the air outlet. You can't hear
the air coming out. either. because
1t first has to pass through a large
silencing chamber before it reaches
the outside air.
Finished in an attractive black
"crinkle" finish these new valves
make an excellent appearance and
may be installed on even the new
thin radiators without moving the
radiator away from the wall.
Now that cold weather is with
us again 1t becomes increasingly
difficult to supply our rooms with
a proper amount of fresh air. If
the wind Is blowing, and rain or
snow are falling, the usual pro-
cedure is to keep the windows tight
ly closed and ventilation goes by
the boards. Wouldn't it be a good
idea to provide each room with
so that regardless of the weather
outside you could be sure that the
air inside your house is fresh and
pure?
With heating plants in opera ton
In houses all around you there is
also a considerable increase in the
amount of dust, dirt and SCOT which
is floating around in the air. This
kind of dirt is particularly difficult
to remove from curtains and deco
ration and if some means were pro-
vided for eliminating the material
which causes this trouble your pock-
etbook as we'll as your temper would
be saved lot of wear and tear.
Device Fits window Frame.
A device which will take care of
both of these problems can be in
stalled quickly and easily in any
window frame. 1t consists of a
metal cabinet which fits under the
appraised sash, and is equipped with
side panels which fill in any open
space which might be left on either
side. The cabinet is nicely deco
rated to fit in with the furnishings
of practically any room, and if you
want to, you can have 1t painted
to match the woodwork or other
decorative trim. Inside the cabinet
are located filter and fan which
cleanse the air as it is pulled in
doors and force it out into the room
The filter is one of the glass-fiber
type, and is easily removed from
Its snug position in the back of the
unit. 1t will last a long time even
though 1t extracts an amazing
amount of dirt and dust from the
air passing through it. and may
be replaced at a moderate cost.
Air is circulated in the unit by
means of a three -bladed electric
fan. mounted to prevent noise from
vibration, and designed to move a
large volume of air with a mini
mum of noise. You can vary the
amount of air which is brought
into the room by turning a simple
variable speed control, and the di-
rection of the air Is governed by
outlet louvers on the front of the
cabinet.
