Aladdin filler caps
So far I have identified 12 versions of filler caps
used on Aladdin lamps. I'm sure there are more out there that I
have yet to find.
IMPORTANT NOTE: This page is based upon what
I have found on my lamps. There is always a possibility some caps
are not original to some lamps. If you have any additional data
points or have identified additional caps I would love an
e-mail from you.
Help: I need additional data points for "Cathedral"
filler caps. I would appreciate owners to measure the thread height
of their "Cathedral" filler caps (1/4" or 5/16ths)
and email me with the data.
1. Vented flower top cap
- This cap was used in models 1 through early 5 (burners with
slots on the side of the base)
2. Non vented flower cap
- Model 6 and probably late model 5 lamps had non vented filler
caps. The redesigned burner base (burners with round hole
screen like sides) eliminated the need for a vented filler cap.
3. Smooth recessed cap, concave
top - This cap was used on models 7 through 21C metal lamps.
Also used on the" Colonial" model B glass lamp. Thread
4. Convex rounded top, recessed
cap - This cap was used in conjunction with recessed metal threads
on Model A "Venetian".
5. Short sided raised cap
- This cap was used on glass lamps starting in 1935 with the
"Corinthian" and was used on glass lamps through the rest
of model B production.
6. Long sided raised cap
- The first use I have seen of this cap is the Brazilian model
C quilt pattern glass lamp. It is the standard cap for model 23
7. Big recessed cap -
This cap was only used on the model 23, 70th anniversary lamp.
8. Long thread recessed cap
- This cap was found on a "Cathedral" lamp. Thread
9. Smooth recessed cap, convex
top - This cap is used on model 23 brass table lamps
10. Recessed Bakelite cap
- Used in model 14 lamps with Bakelite bowls Earlier lamps
had plain top as shown. later caps has "Aladdin' embossed
on the top. These were made in several colours.
4. Recessed threads
and cap used on the model A "Venetian". I'm not positive
but I currently believe the threaded insert was also used in all
model B glass lamps that used a recessed cap. It is a match for
the model B "Colonial"
