Hello all, and welcome to another episode of The Sunday Gas.
This week features what I think is one of the best propane lanterns ever thunk up;
The Bernzomatic TX750 Dual Beam.


2.jpg 

Ha-ha!  It's a Bernzomatic Dual Beam that's not even a Bernzomatic!  This one was
rebranded for Sears to sell as their J.C. Higgins sport brand, but it's all TX750
under the tin badge.




1.jpg 

Great looking lantern in my eyes, and really well thought out.  It works as a lamp
and a lantern equally well.  As a lantern it makes quite a wide beam, but obviously
does not project light behind it.  It also has a screen in the bottom of the frame
so light is projected straight down.  The bright nearly mirror finish on the
reflector makes for lots of light.

As a lamp, it will sit flat against any wall without being concerned about the wall
getting scorched.  It also has mounting holes in the back side so you can hang it
on a wall like a light fixture.  It excels at that!




3.jpg 

On the back side you can see the mounting "keyholes", which let the lantern be
easily mounted on and dismounted from a flat wall.  We also see a good deal of
instructions for lighting and for cleaning out the gas tip by utilizing the fuel
pressure in the propane bottle.




4.jpg 

Louvers...   'Nuff said.  [smile]




5.jpg 

Rubber baby buggy bumpers, and the sometimes present mantle and spare tip clip.
This clip is not on all Dual Beam lanterns.  Some just don't have one.
There is also the finger sized hole in the bottom.  Bernz did make a converter
hose for using a larger propane tank with this lantern.  Maybe, as some folks have
guessed, this hole is for the optional propane hose.  I haven't seen that kit, so
am not sure, but it could be.  Obviously, the hole is partially obscured by the clip
on this particular, but as mentioned, some have no clip, providing a straight shot
up through the lantern, to the valve fitting.




6.jpg 

Now going over a few of the features of the TX750;  All of these I have seen in
pictures, and the five I own have had ceramic burner caps.




7.jpg 

This is the bottom bug screen, which also allows light to be projected downward.
The red arrow points to a keeper spring, which keeps the globe inside the lantern
when the bottom is opened up for lighting the mantle.  Otherwise it could just
fall out.




8.jpg 

This is the top portion of the air tube.  The fuel line and gas tip slide inside
this part as a propane bottle is put into the lantern.  This tube is brass, and
you can see one of the air holes that feed the mantle.  Some are made of steel.
Inside this piece is a small restriction where the gas tip rests, so the gas tip
cannot below the air holes.  As propane flows through the gas tip and it zips
past those air holes, it draws air in with it.




9.jpg 

This is the gas tip and fuel tube which are part of the main valve.  You can see
a kind of crimped or rolled portion just above the end of the fuel tube, and
about 1/4" inside there is a small o-ring.  The tapered part of the gas tip on the
right goes into that o-ring as you screw in the gas tip.

This tip is for normal operation, at regular altitudes and temps a ways above
freezing.  You can see the grooves that have been cut into the hex head of the
tip, indicating the orifice is the standard size.  The lanterns came with a second
gas tip made for operating at higher altitudes and cold weather.  That tip has
no grooves cut into the hex, and that is the way to tell them apart.




10.jpg 

This fitting can be loosened a little so the fuel tube can be adjusted slightly.
Recently Mike (Trout) found he had to adjust his TX750 valve in this manner so
that the fuel tube would go into air supply pipe in a way that would allow all
his various propane bottles work on his lantern.  We learned something from his
troubles! 




11.jpg 

The valve is similar to a lot of Bernz valves.  I'm showing this as a prelude
to the next picture. 
To remove the valve wheel and stem, open the valve about one turn, then loosen
and back out the small hex nut seen here on the shaft, next to the valve wheel.
Take that hex nut all the way out, then keep opening the valve until it comes
out.  That hex nut just keeps the valve shaft from backing out all the way.  There
is no packing like on a Coleman CF lantern.




12.jpg 

With the valve stem out, you can get to this o-ring.  This is a place that leaks
on some of these lanterns.  The o-ring is forty or more years old, and they can
become hardened and will leak.  Sometimes they shed a small chip or two of rubber,
and it ends up going through the valve seat.  Then they will plug up the works.
The o-ring can be replaced with a common size from NAPA or Ace Hdwe, and stores
like that.
Besides this and cleaning the gas tip, there is not much more to go wrong. 




13.jpg 

J.C. Higgins, thanks to old Mr. Otto B.  [smile]




14.jpg 

Time for the light up, finally.  They are about like a 200A and mine run around
nine to ten hours going full blast.  Less with the high altitude gas tip, though.
These lanterns are very adjustable, and will go so low as to be almost no light,
but for a little fire inside the mantle.




15.jpg 

Did I mention how much I like these?  A lot.  In one of those silly (or horrible)
only-one-propane-lantern-allowed situations, I would take Bernzo Dual Beams.

Well, that's it for another one of  "The Sunday Gas" things.  If you have a
TX750 Dual Beam you would like to show off, this is the place, 'cause it's
Bernzomatic Dual Beam week on The Sunday Gas!

Wow Dean after helping me with mine ALL last week I thought you wouldn't want to see or talk about one of these for a long while. LOL!

I won't clutter the Forum re-posting pics of mine, they can be seen here: http://www.colemancollectorsforum.com/post/tx750-question-7009645

I really like this lantern and especially like the shadowless light that comes out the bottom!  Hang it from a shepards hook at the edge of a table and you can do sudoku and crossword puzzles at midnight.  [smile]

One question I haven't asked or tested for myself YET; Do these get too hot to set on a table to burn for long periods of time?

Thanks for the posting.

Very nicely dissected, Dean!

There was also a (presumably later) 750i Dual Beam model, the "i" being for ignitor? instant? The tall button on the back left activates a piezo-electric sparker inside the mantle for instant ignition. This one has no clip on the bottom. They originally came with a propane cylinder in a matching green color. The top heat shield is chrome plated.

I've seen a few ads for these, dated from 1960 - 64, but by no means a definitive date range. I haven't seen an ad for the 750i model.

Interesting John.  Do you have any photos of the ignitor setup in the mantle?  I'm curious as to how they did that. 
Appears like they dropped the double layered lid/heatshield and went to an aluminum valve with that one too.

I don't remember what the burner cap looks like, and I'm too cheap to remove the mantle. I can feel the igniter actually going through the burner cap, like it shows in the diagram.

I'm all in on this one Dean-O, as these Dual Beams are my favorite also. Here is a pic of my setup, including my single burner stove...

On the stove I fabricated a PVC base as the propane bottles normally hang from lid and did not allow lid to be opened upright without falling backward. They later added a pin to hold lid open.This is my hunting duo that I take to the woods each year,,,,campinut...

That's odd! Is that the one you got from Wolfie at the same time I got mine (or maybe I got mine the next time I was there)? I didn't notice that bottom piece, of course they both had about 1/4" of dust on them at the time. My avocado model has a screen.

Burns nice and steady. Quiet too, and as Dean said it throttles right down to a few candlepower.
Great for late night.

Thanks Dean for another fine tutorial and for The Sunday Gas.

Dean.... Awesome write up indeed!.

need more of those here and yours is a great example of how to do one.

love these lanterns. I can imagine a getaway cabin with these. or their use after winter storms or the southern hurricanes for folks to find their way home at night.

will definitely grab one if found wild

Neat pix!  Interesting - the subtle differences in essentially the same lantern - presumably over time?

Dean's pic has the chrome(?) "chinstrap", the avocado models have valve with knobs on top instead of the side, screen bottoms and stamped holes... 

I just noticed something I hadn't seen before - the contour of the frame at the bottom of the globe - cut low on the Higgins and Bernzo in the middle, straight on the others.  Maybe those are earlier?  Labeled as Higgins before Sears, and going from aqua/red vent to blue/chrome vent and avocado on Bernzo?

A couple of mine have only one vent cover.  I just thought the inner one with holes was missing, as in someone didn't put it back on, but the TX 750PI above only has the single plate.  Mine is the same - maybe that's the way they came?

I only have one of these and would jump at another if I stumble upon one. There was one at the convention this year in great condition, but I had already blown most of my money and passed on it. I wish I had a place to use mine around the workbench in the winter. I may have to work on that. Thanks again Dean!

  I don't understand the cold weather/high altitude tip.  These seem to be the opposite direction for mixture.  In cold weather, the air is denser and would require a more fuel (larger orifice) for a proper mixture.  At high altitude, the air is less dense and needs less fuel (smaller orifice) for a proper mixture.   Doesn't make sense to me.  Any thoughts or comments?

Dean,

Nice write up and the dual door light pic, only way to make that shot better would be lit up. Pretty sure these Bernz Lanterns were std in our BSA Troop as light source at the campsite pavilion, the leaders domain. Not given a whole lot of respect, these were tools meant to be used.

Also reminds me of a Bernz O Matic propane radiant heater we had. After we used it for long time and then shelved it, Bernz had a safety recall. It had a two position bayonet fitting, in to start, pull out one notch to run. I think they had a few problems with folks not pulling it out one notch, hence the recall. They paid $60 for its return IIRC. I wanted to turn that back into a camping item, bought a 20" Lodge cast iron monster skillet.

I don't know the exact answer or reply to these comments, Dave, but some of the
consideration is not to do with cold air.  It's that when propane gets cold, it doesn't
boil at the same rate as on a warm day.  It gets cold, less propane vaporizes, so
the lantern needs a larger orifice. 

For the altitude, I'm not sure.  Higher than sea level does change the vapor or boiling
point of liquids.  I don't know if that works for compressed and liquified propane, but
it does once the propane gets to the atmosphere. 
Other people can answer this better, I'm sure.

Thanks loads Dean for posting this. As you know I recently found one with all the goodies and its up and running but will need spacers et al. for the vent plates.  More functional than the Bernzo/Turner Brass Works- Buck Rogers rocket looking lantern IMO. 

I like it because its truly from the classic Coleman era and represents one manufacturers way of providing an adjustable lantern long before the schrader valve. Simple. Sometimes,one of these outside the cabin door is just what this camper ordered. Classic looks.

Dean, thanks to you and this thread I've settled my TX-750 vent issues. And Phil, good info on cap replacement options with the 200a. I was wondering.

I found out last night the PO had lost a spacer(?) between the baffle plate and the top vent plate plus the support across the top with the vent stud was pushed down a bit. Probably got dropped on its top at some point.

I just pried the vent support up, put the baffle plate in the vise a few times, and added an old M1950 brass fuel cap/ring that had been cross threaded as a space between the vent plates. Reassembled it. 

P.S. the vent color is pretty much a Ford Engine Red (ala Kamplites) as mine was scorched from being run without enough vent head space and got repainted. 

Niiiiice runner. Thanks.
