Hi All, Had 2 of these Lanterns and finally decided to conduct an autopsy to determine if I had 2 kero, 2 gasoline or 1 of each. The only difference in the 2 was the generator. The " S " type. The results. As can be seen there is a noticeable difference in the relevant tips. In reading the Akron Catalogue of 1920 they produced a " Match " lighting and a " torch " lighting generator. From observations I would say the match lighting [ gasoline ] is on the left, the torch lighting [ kerosene ] on the right. You will notice no packing in the torch lighting. There was no difference in the valve / fuel pick ups of the 2 In summary the smaller depression in the gas tip appears to be the gasoline. I now have a 107 G & a 107 K
Sorry but no you don't. Both those are match lighting gasoline generators from after 1922. The torch lighting generator mentioned in 1920 is a heavy straight brass tube not the droopy S you are showing which was patented in 1922. The 1920 match lighter is the same heavy brass tube but with a modification to enable match lighting. Nothing at all like these two. I will have a hunt in my images and see if I can post an image of the 1920 match lighting gizmo. ::Neil:: OK have a look here 1919 Akron Diamond Model 92 That lamp has the match lighting generator fropm 1919-1920. The torch lighting type is the same heavy tube but without the 8 shaped thin tube at the top but direct into the mixing cross head. ::Neil::
I have a NOS Akron "S" generator in the package. It has the same gas tip as those shown in your images. I was told that if the gas tip has "rounded" edges it for gasoline. If it is "square" it is for kerosene. Bob
Thanks for the info Bob, You know if I look at those images up the top long enough and hard enough the one on the right turns square !!!!! According to the Mathew's Chart the orifice is 0.0075" Colin
Hi David, I don't know if there is a "link" to it. It's in the form of a HTML document that can be sent as an email attachment. The "image optimiser" won't take it for a download. I have it stored in "My Documents". I would need an email address of one of the admins to send it. Maybe they could post it to the forum. There is a "list" for stoves too. Bob
I just checked an Akron 102 ? that I acquired several years ago, didn't do anything with it as I already had one. Maybe I should have. In any case this has turned up ..... As can be seen a square tip. Can anyone verify that Akron used these Gas tips for kerosene? Colin
Yes that's right. Akron describe their generators as Gasoline oval tip and kerosene square tip. That is the first kero gas tip I have seen for these. They are not at all common. Nice find. Here is a parts list from 1929. ::Neil::
Thanks All for the info. Started out with a misguided 107 G & 107 K ended up with a 102 G & 102 K. Happy with that. Colin
Hi Colin, The NOS gasoline generator that I posted the image of has a recessed orifice. The latest image you posted the orifice appears to be flush with the surface. It also appears that a wrench could be applied to any opposing sides. This may be the "square" that was spoken about. Whether the wire gauge size. Here in lies a "conundrum". Case in point. The Coleman T44 gasoline two mantle generator is shown to have a "V" gas tip. The TK44 two mantle kerosene generator has the same tip. The difference is the tube fill construction. Info shows that the Akron "S" generator has a .0075" gas tip orifice for what I assume to be a gasoline generator. WAIT A MINUTE!!! Just checked scan of a piece of Akron paper I got from Joe Pagan a long time ago. A parts list with drawings for the 103, 131, 132, 132A, 133, and 134A. OK, here's the deal. It shows that there were two generators of the "S" type. The #318G(oval tip)5 for $1 back then. The 318K(square tip) 4 for $1. No mention of gas tips. I'm afraid that this paperwork won't transpose to well. It's one of those 8.5"x11" that's folded twice to make a pamphlet. Small print. Hope this helps some. Bob
Hi Bob, Yeah, still working on it. Appears to be kerosene if you go by the paper trail. Will have to chase up someone that can measure the orifice. Interestingly there doesn't appear to be any packing in this square jet [ U can blow through it ]. I have to check out the top image RHS as this appears to be minus the packing also. The orifice size seems to be the way to go. Colin
Hi Colin, Have you had the gas tip removed from the kerosene version? Is the inlet screen still there on the gas tip? If there is no fill in this one you might ry a piece of Zippo lighter replacement wick as a substitute. Maybe no fill is needed for kerosene. With no fill material it sure would make it easier to clean if it carboned up. Now the only question is with no fill will it show signs of Liedenfrost Effect? Bob
Hi everyone, New here to the CPL. I recently bought a Akron 107 Diamond lantern. I am in the middle of rebuilding and cleaning it. The info above has helped a lot. Unfortunately the gas tip on my S style gen is over sized and allows to much fuel to pass. I'll try to post some photos of my lantern.
@Kgam1020 Welcome from Queensland Australia. You’ll find a lot of friendly help and advice on techniques here. I’m looking forward to seeing your pictures of your lamp / lanterns projects. Cheers Pete
Here is my Akron 107 Diamond as found. I believe my lantern is the gas version. The gas tip is seams to be over sized. I rinsed the fount and filled it with fresh CF. Preheated the generator and all I got was yellow sooty flames from the burner caps.
