PRINCIPAL LAMP
CHIMNEYS
I do not sell
chimneys. The information below is only to provide more
information for lamp owners. Check the
Links page
for chimneys for sale.
The following list is by base diameter only -
not shape. The actual shape of a chimney directs the flow of air
and flame in such a way as to create the most flicker free, bright
light possible. One major problem is that chimneys of the correct
original design can be almost impossible to find. For example, the
original 2 3/8" Success chimney has a short, small bulge. Modern
replacement 2 3/8" chimneys appear to be made from molds designed
for duplex lamps - not a center draft lamp. They work, but not as
well as a chimney made to the original specifications.
The symbol , referred to as line, is an
old measurement that changed from country to country. For
comparison, a 20' lamp was rated as 50 candlepower and a 30
as 100 candlepower when the lamp was a center draft design using a
circular wick. The system of line measurement is of German origin
and was widely adopted. There is no exact conversion of line to
chimney dimensions or wick sizes.
The following table, taken from an old British
publication, lists the principle chimneys and globes and gives
their dimensions and fittings. The list gives alternative names
where they are known. You will note that some lamps are
listed under various sizes - they varied. This is a
guideline only...measure your lamp to be sure of the size chimney
it requires.

CENTER DRAFT
LAMP CHIMNEYS
The chimney holders should be adjusted (bent)
so they only gently hold the chimney in place - NOT TIGHTLY!
These lamps produce a lot of heat and glass expands with heat - if
gripped too tightly, the base of the chimney will break. To
avoid breaking the brass fingers which hold the chimney in place,
use a smooth bladed paddle pliers to bend the fingers, holding the
base of the finger with needle nose pliers.
Many P & A Royal lamps used a 2 1/2" fitter for
the chimney, whereas B & H usually used 2 5/8" chimney fitters.
The fit of the chimney to a center draft P & A lamp is quite
critical. The height of the glass chimney from the base to
the bulge should be 1 1/4" and the opening at the top of the
chimney should be 2" minimum. There are quite a few cheap 2
1/2" chimneys for sale which have a height from the base to the
bulge of 1 5/8" and an opening of 1 3/4": the flame spreader is
not in the bulge, but within the 2 1/2" base diameter. These
lamps generate a considerable amount of heat, and the combination
of a restricted airflow with a 1 3/4" top opening and the flame
spreader not up into the bulge often results in the chimney
cracking horizontally at the base of the bulge on the first
burning! Those $4.10 chimneys that appear to be a good
buy turn out to be not so charming when they break the first time
you use them!
"The chimney HAS to be right. Your wicks won't
perform properly if the chimney isn't exactly right. I have
experimented with several chimneys hat ''fit'' the Success burner
base, but there is a vast difference in how the flame works. I
wish I could be more descriptive, but there were major
differences. One chimney produced a perfect flame while another
produced ''spikes'' of flame that prevented the wick from being
raised properly." Dick Stauffer
Any air leak at the base of the chimney will
cause excess oxygen to enter a gap and upset the delicate air/fuel
balance, resulting in "spikes" of flame. One potential
"cure" for chimneys which cause a "spike" of flame is to flat sand
the base of the chimney. Modern chimneys are made pretty
cheaply, and often the base is not level. Using 400 grit
emery paper on a perfectly flat surface, gently and carefully hold
the chimney base flat on the sandpaper and gently stroke straight
away from you. Lift the chimney, return it to the front of
the sandpaper and make another stroke. Then look at the base
of the chimney. If you see a dull spot, that is a high place
that got sanded. Sand the base again until all the gloss is
gone, and therefore all the "high" places are sanded down even
with the "low" places.

* As far as chimneys are concerned, most Junior
size lamps are not picky when it comes down to chimneys. The Rayo
Jr. gallery and burner are the most tolerant. The lamp burns well
with both vintage chimneys, modern Czechoslovakian chimneys and
cheaper Chinese imports with the longer than normal necks.
The B&H Junior uses an unusual 2 1/8" X 8 ½"
chimney. The only replacement that I could find that fits is an
cheaper Chinese import. Fortunately, the chimney fits perfectly
and burns perfectly with the taller neck since the flame spreader is
quite tall in the B&H junior.
The Plume & Atwood Royal #1 burner works the best
with a vintage 2" X 8" junior chimney. The lamp burns with a very
bright, clean and steady flame. The longer neck of the cheaper
Chinese import causes the flame to flicker. The P&A flame spreader
is short and does not have a stabilizing disk. The long neck of the
chimney results in over-drafting and flicker. Modern Czechoslovakian
chimneys dont fit. The lamp gallery only accepts a chimney with a
2" fitter. These chimneys are ever so slightly bigger at the
fitter
. No good. The lamp would probably burn well should the
chimney fit. There is enough draft in the lamp design that a shorter
6 Ύ" chimney burns cleanly. The smaller chimney looks nicer on a
finger lamp, more proportional to its small size. Notice that the
P&A Royal burner, even in the #1 size, uses a wick that is slightly
thicker than the rest, as is the case with the P&A size #2 burners!
In my opinion, the lamp manufacturers did not
standardize the junior size at all. Just look at the draft and wick
tube diameters. Finding a wick for each lamp is nearly impossible.
Finding chimneys for them is not that much easier either. For
example, the Rayo Jr. wicks do not fit any other junior lamp.
Fortunately for Rayo Jr. owners, Miles Stairs #1 wick is a perfect
replacement for the Rayo lamps
. but to my dismay arent wide enough
for any other lamp. The B&H junior lamp not only boasts an oddball
wick, but chimney as well. I could not find any vintage 2 1/8" X 8
½" chimneys. Fortunately the cheap 2 1/8" cheap Chinese import
chimneys fit perfectly. Their longer fitter neck mates well with the
tall flame spreader of the B&H junior lamp, resulting in a tall,
bright and clean burning flame.
On a positive note, junior lamps are beautiful in
their own right. Their small size makes them attractive almost
anywhere. They put out a good amount of light while being thrifty on
fuel at the same time. They are brighter than 15 Matador lamps.
The Rayo Jr. is certainly no "fuel hog" as its full sized cousin.
They do not put out a tremendous amount of heat but radiate enough
infrared heat to keep you cozy on a cold day. The few junior lamps
that I have come to own burn very cleanly. The Miller junior and
Rayo junior burn better (IMHO) than their full sized cousins.
Unfortunately, they are not as common as their full sized
counterparts, even on Ebay. If youre lucky enough to own one of
these gems, consider making it work if it doesnt. You will not be
disappointed with them!
