Aladdin Heat Deflectors (Smoke Bells)
What we today call smoke bells were officially called heat deflectors by Aladdin until at least 2000. I will use the term "smoke bell" instead of the proper "heat deflector" name because smoke bell is in common usage today and I don't want to cause confusion.
Incandescent mantle lamps work by the burner creating enough heat to cause the mantle to glow. A properly adjusted mantle lamp burner can produce a flame of around 2000 degrees Fahrenheit. The hot burned gases flow up the chimney straight towards the ceiling unless there is something present to disrupt and disperse the column of hot gases. If the top of the lamp chimney is within five or six feet of the ceiling, the heat reaching the ceiling can be enough to damage the ceiling paint or start a fire. Back before World War II when the standard house ceiling height was twelve feet high, heat scorching the paint on a ceiling was only an issue with hanging lamps and not table lamps. With a smoke bell installed the top of the hanging lamp should be at least 24 inches below the ceiling. Smoke bells came standard on Aladdin hanging lamps and were an option on the tall student lamps. In 2014 Aladdin introduced a smoke bell that fits on top of a chimney for use with table lamps.
Bill Courter properly pointed out that "The Aladdin lamp does not make smoke. The lamp makes heat which incandescences the mantle. The term" smoke bell" was not used by The Mantle Lamp Company of America. The term smoke bell described glass or metal devices hung over the chimney of early non-Aladdin lamps. The term smoke bell, however, is used by collectors of Aladdin lamps today." Note that Aladdin introduced a product they named a smoke bell in 2014. This page uses the term "smoke bell" so as to confirm with today's common usage.
Scallop smoke bell for model 1 through 6 hanging lamps
including the model 3 & 4 narrow frame and model 6 125-A hanging lamps.
3-1/4 inch diameter at outside of scallops, 3/4 inch high
Note that there are some brass smoke bells that are duplicates to the early steel smoke bells.
These were sold by the American lamp Supply, "NO. 102-1A Smoke Bell" for a short time in the mid 1980s.
Introduced in winter 1984
they may have come on early brass tilt frame hanging lamps sold by the American lamp Supply.

Model 7 & 8
The drawing is from the model 7 hanger patent.
Since Aladdin used up parts on hand when they transitioned to a new model lamp,
it is very likely that early model 7 hanging lamps came with the model 1-6 smoke bell..

THEORY NOT PROVEN FACT:
The smoke bell used on the model 12 four post hanger and the subsequent model 12 and model B tilt frame hangers look identical to the model 7 & 8 smoke bell pictured in Aladdin factory photographs. When Aladdin started making the model 9 through 11 smoke bell they designed and used a new different smoke bell. When they designed the model 12 four post hanger, the model 11 smoke bell was not a good fit, so my theory is that they dusted off the old model 7 & 8 smoke bell tooling, drilled a single hole in the center top and mounted it upside down to get a good fit with the four post hanger. Then they continued using that smoke bell tooling through the tilt frame production. Reuse of existing tooling would be economical and would explain why the smoke bells look identical.

Model B tilt frame smoke bell
3-1/8 inch diameter, 3/4 inch high
This smoke bell is the model 12 four post smoke bell turned over and with a second hole drilled.
It was used on model B tilt frame hangers through WWII. The tilt frame hanger with this smoke bell appears in the 1946 model year catalogue,
and was replaced with a new smoke bell and hanger for the 1947 model year.
All tilt frame lamps (pre-model 23) sold world wide used this smoke bell.

Because brass was a restricted material, smoke bells manufactured during World War II
were made of black oxidized stamped steel

Model 23 chimney mounted smoke bell - Aladdin catalogue number R960B
This Chimney mounted smoke bell, introduced in 2013 will fit all Aladdin lamps plus most mantle lamps of other brands produced after World War I.
This will diffuse the hot gas coming out of the chimney over a wider area to prevent ceiling paint scorching.
