Any piece of handwork can be a source of pride for the doer
and of inspiration for the admirer. Moreover, when art
serves a purpose beyond its aesthetic value, it can become
even more worthwhile . . . and our unusual heat-circulation
lamp is a good case in point.
The unit is really nothing more than a copper shade that's
fitted with a bulb and a perforated light shield . . . but
just below that tungsten globe hangs a muslin
"sock" — a tube about eight inches in diameter and
six feet long — which has a small electric fan housed
in its foot.
And, as noted above, there are practical reasons for this
attractive combination of components. Besides providing
warm, diffused illumination, you see, the fixture draws hot
air from the ceiling area (where it naturally collects) and
pumps it down to floor level (where chilly drafts seem to
run rampant). So the device not only makes efficient use of
available warmth — increasing the usable heat
provided by your woodstove, for instance — but
furnishes some degree of air circulation, too.
MOTHER'S research director, Emerson Smyers, came up with
the idea while reminiscing about the old-limey paddle fans
that graced many a residence and public place not too long
ago (and have recently made quite a comeback). "Most people
think they were there for cooling, but they're only half
right . . . those big blades did a heck of a job
circulating heat, too, and anyone who doesn't believe it
should take a closer look at some of the original models.
Many actually had resistance elements built right around
the motor housing that could be switched on in the winter
to throw off additional warmth."
In an effort to adapt that technology, Emerson merely
designed a more compact package and placed his fan (which
uses about one-quarter the energy required by its
predecessors) out of view. The result — which would
cost about $45 if all new parts were used (naturally, we
scrounged some of ours) — required a 19" X 27" sheet
of 16-ounce copper (this item can be purchased as scrap for
a couple of dollars), a porcelain socket fixture with a
threaded mounting stud, a swag light kit with a switch, a
150-CFM (cubic-foot-per-minute) 8"-diameter circular fan
(available from Solar Usage Now, Dept. TMEN, Box 306,
Bascom, Ohio 44809 . . . write for catalog ordering
information, or use any comparable muffin fan and adapt the
design to fit it), about a foot of 1/4"-loop wire chain, 2
yards of muslin cloth, three lengths of copper-coated 1/8"
welding rod, 8 feet of speaker wire, seven 1/2" plastic
tether rings, a 4" X 27" scrap of sheet metal and a piece
of foam rubber of the same size, and a half-dozen small
sheet metal screws.
