The Aladdin model 7 lamp was a completely new and revolutionary lamp in every sense of the word.

The model 6, propelled to fame by winning a gold medal at the 1915 World's Fair in San Francisco, was extremely successful for The Mantle Lamp Company. Popularity and sales were at an all time high and The Mantle Lamp Company decided it was time to design their own lamp from the ground up.

If you look back through Aladdin's previous lamp offerings you can see that the Aladdin model 7 was the very first lamp that was truly an all Aladdin lamp.

The models 1 and 2 were made almost completely from existing Plume & Atwood lamp bowl tooling. Model 3 saw Aladdin's first real engineering improvements. But they basically added an improved wick adjusting mechanism, new gallery, mantle and generator to an existing mix of Plume & Atwood tooling.

The models 4, 5 and 6 were basically marketing upgrades with very minor actual improvements over the model 3. The most noticeable change was the model 4 generator which is a generic P&A style. The generic P&A style was more robust and worked better with the Kone-Kap gallery.

There was some sort of licensing or ownership arrangement between The Mantle Lamp Company and Plume & Atwood that allowed P&A to use much of the Aladdin tooling to manufacture lamps for other companies as well as Aladdin.

As an example the Solar lamp was in marketing competition with the Mantle Lamp Company selling what is basically an Aladdin model 1 quart and a half table font crowned by a Solar labeled Aladdin model 6 burner. Because of this licensing or lack of tooling ownership, Aladdin was basically in competition with it's own lamps.

The model 7 tooling put an end to all that and for the first time a uniquely Aladdin lamp was offered

Aladdim model 7 burner

The Aladdin model 7 burner, like the rest of the lamp is completely new in every sense of the word. If you look at each new feature on the burner you can see how it was added to address what was likely a common customer complaint. Not only was the model 7 going to be different that the other P&A manufactured mantel lamps but is was going to be very noticeably better. With the model 7, the Aladdin sales force was going to have a real answer to the other company's sales force when they said "It is exactly like an Aladdin, only cheaper"

 

Inner wick tube

One very noticeable item that visibly separates the model 1 through model 6 lamp bowls from the model 7 and later Aladdin centre draft bowls is the inner wick tube. On earlier models the tube went from the bottom of the lamp bowl to the top of the burner. This soft brass tube stuck out above the top of the bowl a couple inches where it was very susceptible to damage. The inner wick tube has to remain centered in the burner and have no dents or creases in order for the lamp to work correctly. Damage the tube when replacing a stuck generator, or by accidentally dropping the lamp with the burner off and the lamp will never burn right again unless you are skilled in brass work.  The Aladdin model 7 introduced a split inner wick tube with the top part attached inside the burner with 2 arms.  This assured that the inner wick tube would be concentric with the outer wick tube and that the wick would be able to move more freely without the wick tubes pinching it on one side.

The new lower inner wick tube tapers to a smaller diameter at the top and the new upper inner wick tube is firmly secured at its base. This means the bowl's inner wick tube can get bent or otherwise damaged and easily be made to fit to the burner. The side to side gap between the between the two tubes lets air into the bowl to equalize air pressure as the kerosene is drawn up into the wick. Past solutions were vented filler caps or holes drilled into the side of the inner wick tube.

Having a short top inner wick tube firmly affixed to the base of the burner virtually assured that the inner and outer wick tubes would remain concentric and allow easy wick movement. And if an accident happened to the inner wick tube top edge, you replace the burner and not the entire lamp.

This one change required several other changes to the burner. Suddenly there were these two arms blocking the space between the inner and outer wick tubes. Model 6 and earlier wicks were mounted from the underside of the burner. The top inner tube support arms required that the model 7 wick be mounted from the top.

Aladdin Lamp wick carrier

The unreinforced wicks used at the time did not lend themselves to customer mounting. The length of the wick above the the holder is important to proper wick adjustment and the unreinforced wick is quite fragile. Aladdin burner design requires the wick gear to be inserted from below.

Aladdin's first attempt to solve this new dilemma was the model 7 two piece wick carrier. You detach the gear from the carrier then slide the mounted wick down from the top. Next you fit the carrier gear to the burner gears, run it up to the bottom of the carrier and lock it into place. There is a gear lock on both sides of the wick carrier so you can never insert the wick backwards.

You could consider the removable gear as Aladdin's first wick holder that attaches to the wick carrier as does the model 8 and early 9 holders did.

To insert the wick from the top you need a removable outer wick tube.

Aladdin made the outer wick tube two piece with a removable top section and permanently mounted the air distributor to the removable outer wick tube. This provided physical space to get the bottom wick ends through the base and to hold onto the wick carrier while inserting the wick over the inner wick tube. It also allowed access to the outside of the upper inner wick tube to keep it clean of carbon deposits that can inhibit smooth wick movement. There is a very short section of outer wick tube built into the burner base that the bottom of the removable tube slides over.

Aladdin lamp generator

The new burner with removable wick tubes required a longer generator. Aladdin still needed to produce model 6 generators for the model 4 through 6 replacement parts market. So rather than spending money for a second set of generator tooling they added a brass skirt to the bottom of the generator created by the existent tooling. The lettering on top of the generator is formed by relatively inexpensive dies inserted into the tooling.

It is quite conceivable that the same basic tooling was used to form Aladdin and competitor's generators from model 4 through 11 with just lettering die changes.

Aladdin Lamp burner gears

Another customer issue the Mantle Lamp Company addressed in the design of the model 7 burner is the wick adjuster gearing. The model 3 gearing, used through model 6, was a single gear at the end of the adjuster shaft. Fine adjustment of the wick needed to achieve the most possible light without sooting was difficult. Also, if the wick or wick tubes were dirty, turning the adjuster knob could be difficult.

The redesigned model 7 burner introduced gear reduction, making fine adjustment easier and with less effort.

Of course all these additions took up space and the new burner base had to be made with a larger diameter. Which, coincidentally meant that if one wanted to take advantage of these new features one had to purchase a new lamp and not just a burner. Also, that Aladdin burners could not fit competitor's lamps.

Aladdin Lamp gallery
Model 7-8 gallery left & 9-11 gallery right

The top of the new burner is slightly larger in diameter than the previous burners and the burner to gallery interlock is slightly larger and more robust. This required a new gallery. Aladdin Galleries are two piece with a single stamped bottom and tubular chimney attachment section. The finger attachment ring is a friction fit over the upper sides of the gallery base and is held into place by 3 evenly spaced dimples. Though the gallery base of model 3 through 6 galleries look the same as the base part of the model 7 through 11 galleries the dimensions of the newer gallery are slightly larger. Generally by 0.1 inches or less in each dimension.

Aladdin Lamp shade tripod

The model 7 lamps got 3 entirely new glass shades and an entirely new shade holder tripod. All tripods previously sold for Aladdin table lamps had been mounted on the gallery. Lighting the lamp required removing the shade then removing the gallery to put a match to the wick. A shade attached to the base of the lamp does not need to be removed in order to light the lamp.

Note the inner lip inside the ring. Under burner shade holders on pre-model 12 lamps have a vertical lip/  Under burner shade holders on models 12 and newer lamps have a horizontal inner lip.  This is because of differences in the lamp base construction at the threads.  The shade holders are not interchangeable.

Aladdin Lamp model 7

During the late nineteen tens, more Americans were living in better homes with more and nicer furnishings. People were getting rid of Victorian style furnishings and replacing it with newer styles. Lots of Americans returned from the war with tastes influenced by French designs and Nouveau styles were big in America.

Aladdin jumped into the new furnishing styles market with both feet when they designed the entirely new upscale and fashionable model 7 product line. Aladdin paid for completely new tooling for two new lamp bowls a new wall hanger and a new lamp hanger. Tooling for the model 7 lamps could well have been the single largest expenditure The Mantle Lamp Company had made to date.

Both the hanging and table lamps have a 1-1/2 quart capacity.

The Aladdin model 7 got a whole new ceiling mount and extension.  The body was brass plated cast iron. Nickel plated versions were available for the earlier lamps and the model 6 concurrently being sold in Canada.

 

The model 7 and 8 font lamps were only available with the glass shade included. The Model 7 font lamp wall mounting bracket was originally a model 6 wall mount with the ring expanded to a 7 inch diameter.   The steel 7 inch diameter ring held on to the arm with 2 rivets.  The steel rim was stamped with the same pattern as the mounting ring on the hanging lamps. After release Aladdin quickly found out that the weight of the larger lamp full of kerosene plus the weight of the shade was too much for the wall bracket.  The steel rim tended to bend down from the weight and people handling the lamp.  So early on during model 7 production Aladdin introduced a cast bracket that was a lot stronger than the original.  The cast wall mount is a lot more common than the early ring style wall bracket.

Finish

There seems to be a common belief that the Aladdin model 7 and 8 lamps used a special finish that was different from other Aladdin lamps and very fragile. I've heard it from most collectors and dealers I have talked to since I first started collecting Aladdin lamps.  Of all the brass finish Aladdin lamps, people seem willing to pay a higher premium for an original factory finish on a 7 or 8 than for other early Aladdin brass lamps.  I'm told that this is because the finish is special.  It is time to bust this myth.  The finish is just plain clear lacquer applied over satin finish brass.  Plume & Atwood has been applying clear lacquer to brass finished lamps before Aladdin was founded and continued to do so.  To the best of my research all Aladdin brass finish lamps ever made were finished with a clear lacquer paint from model 1 up through model 23A.  The finish on the model 7 and 8 is no different from that of a model 5 or 6.  The only difference is that collectors are more careful with the finish on model 7 & 8 than the other models.

In the Aladdin sales lists the finish is listed as satin brass, same as the models 5 & 6 before them.  Below is a picture from a model 8 owners manual.  I typed the text below since readability isn't the best.

From the manual page above:

Cleaning the lamp bowl
The Aladdin lamps are all lacquered and will retain their finish so long as the lacquer remains. To clean the Aladdin lamp use a soft cloth - do not use any alcohol or any lacquered or scouring material that will cut or dissolve the lacquer.  If the lamp becomes greasy use mild soap and water."

These are the same instructions you will find in the model 6, 5 and I presume earlier lamp manuals.  There is nothing special about the finish on the model 7 & 8 lamps.  The only thing special is the care taken by collectors and dealers to preserve it.  The old formula lacquers had a golden tone to it which deepens with age.  The lacquers used on Aladdin lamps for the last half century are clear with not colour tone to it.

 

Parts support and interchangeability:

Mantles: Production of Aladdin KoneKap mantles ceased in 2007. In 2012 Aladdin introduced an adapter that fits onto a model 3 through 11 gallery that allows the use of a Lox-On mantle with the earlier lamps.
Wick/Carrier:  Models 8, 9, 10 and 11 wicks can be used if you use the correct carrier for that wick. Model 11 wicks were discontinued in 1955. 
Gallery: The model 8, 9, 10 and 11 galleries can be used.
Generator: Model 8, 9, 10, and 11 flame spreaders can be used. The model 11 flame spreader was discontinued in 1955.
Burner: Model 8, 9, 10, 11 and 12 burners can also be used with this lamp
