Default Friday's yard find: lauson something or another

I came across this lauson in the aircraft parts yard I work in. It's on some kind of heater. I don't know year, but it's real cool so I thought I'd share it!

I used to have one of those. I was told it was used to heat planes on the runways during WWII.

Those are neat units, I've been looking for one for a while. If you get it keep it together.
Mike, I beleive the supercharger is for high altitudes where the air is thinner.

Thing is, the ones we have literally look very runable. There may be some nos tanks somewhere, but i dunno about that. We got 3 out here. All are in runnable condition, but may need a little help first. They're supercharged?!

found this information, Link & what was said.
http://www.lausonsmallengines.org/co...tionGroup1.htm

RSC-514-7


Watch video of my RSC-514 in operation
click an image of a renovated engine on the left to get a larger photo
This version of the Lauson RSC was specifically built to operate a Stewart Warner Model 782 Aircraft Heater, a picture of which is shown on the left. The heater was used on the Catalina PBY flying boat and possibly other aircraft. The engine features a deep oil sump, probably to provide extended hours of operation between maintenance periods. The engine is devoid a governor and is built with a special magneto, used to fire not only the engine’s sparkplug but also a spark plug installed in the Stewart Warner heater’s burner. The engine itself drives the blower on the heater to force air through the heat exchanger. My understanding is that the aircraft heater was used in frigid climatic conditions to warm the aircraft engines prior to starting. Flexible ducting delivered this heated air to areas of need, probably to the engine nacelles.

Lauson does not list a carburetor for this engine and I believe they were supplied to Stewart Warner without one. Stewart Warner supercharged this engine with a roots supercharger when it was installed on the heater.

For exhibiting the engine, I’ve installed a sparkplug as would have been used in the Stewart Warner heater and I’ve included a neon sparkplug test tool so that spectators can see the auxiliary spark plug in operation. This second spark plug must be installed in the ignition circuit for the engine to run.

This specific RSC514 was probably sold out of military surplus at the conclusion of WWII.

2.) Stewart-Warner Heater Supercharger (Model 782-A) used to power aircraft
Southwind type heater system. This example is from a PB2Y-5R but
most of the PBY-5 units were similar. The 2hp. gasoline engine is on the
left and the supercharger/blower is on the right

Yes extremely hard to read. I'm gonna see if I can get the one I found today, and one of the complete heaters. It he deep sump because aviation. Meant to run a long time. I have a ton of old cool stuff all for sale out in that yard. I have round engines, flat engines, various types of tugs, gpu's, small engine driven equipment, etc. I have all kinds of nos and used airplane parts, I could list, but it would take an eternity. I have that much stuff in the yard.

Stewart Warner also made a gasoline heater for cars and trucks. They were good when they worked and when they quit there was very little chance of getting them to work again. I had one in a 1939 Ford sedan till the heat exchanger cracked and let all the exhaust fumes in to the car.
