The LA was introduced around 1930 and is (basically) a larger version of the Model RAY, introduced around the same time period. This engine has an aluminum blower housing and base, making it considerably lighter than my LB.

Many of the engines in this "first generation group" are equipped with Wico flywheel magnetos. This specific engine is equipped with a Wico "FG" flywheel magneto. This magneto consists of a stationary frame containing two sets of bar magnets that create a magnetic field that passes through a set of coils and an armature. The armature rotates in the center of the magneto, driven by a pin on the flywheel. As the armature rotates it changes the intensity of the magnetic field passing through the coils in concert with operating the breaker points; thus facilitating the generation of a spark at the appropriate time. There is no provision to “time” the engine; the magneto mounts at a fixed location to the engine body.

I acquired this engine from a fellow collector in North Carolina.

The LB is an upgraded version of the LA. The LA was introduced around 1930, with the LB in around 1935. The LB is a 2 HP engine, weighing around 120 LBs.

This engine is an assembly of two different engine carcasses, both being deficient in parts to make a complete engine.

I acquired this engine at the Portland, Indiana show as a rusted hulk. I have a renovation article covering the renovation of this engine in my "Articles discussing engine Renovations" section of this web site.


LBM-821

The LBM was built as an air cooled marine engine and it is designed to be operated on a ten degree incline from vertical in the way I currently have it mounted. At 3 HP, I’ll assume this engine was built to power a light launch of fifteen to twenty feet in length but I have been unable to uncover any information regarding the type of vessel in which this engine would have been installed.

This engine was built, starting in the 1930’s and throughout the war (World War II). I have wondered if it saw any military duty or came out of military surplus at the conclusion of the war? For being built in the 1940's, it's design is a "throw-back" to the early 1930's. I'll assume Lauson stuck with this proven design throughout the war. At the conclusion of WWII, both the LB and this LBM were replaced with the PAC and PAM models respectively.

This engine may have originally been equipped with a marine transmission; The PTO side of the engine has an adapter cast into the block to receive one. If the engine originally came equipped with one the transmission was long gone by the time I acquired it.

This engine is equipped with a Wico "FG" flywheel magneto as described above.

I acquired this engine from an ebay auction. I provide a "before" picture of this engine as well as pictures of it after it's renovation.


RAU-M200

The RAU models were first introduced in the early 1930's. This specific engine is an RAU built for Alpha DeLaval to power a cream separator. The engine features a "bottle" oiler; a device used to maintian an adequate supply of oil in the crankcase. This engine develops 3/4 HP.

This engine is equipped with a Wico type "F" flywheel magneto, a smaller version of the Wico "FG" described above.

RAY-825-6

The RAY models were first introduced in the early 1930's. This specific engine is an "early model" RAY and is equipped with a WICO "FG" magneto. The RAY models were a very successful model for Lauson, and many were built.

This specific engine was built to power refrigeration equipment; the PTO powering the compressor unit while the extension to the crankshaft on the blower side of the engine drove a fan for the heat exchanger. The RAY is rated at one HP.

I acquired this engine from a fellow collector I "met" on Harry's SmokStak engine forum. The owner was not interested in Lausons and knew I was. I provide a "before" picture of this engine as well as pictures of it after it's renovation. As you might imagine, this engine was one of my more challenging renovations.


RAY-885

This RAY is a "late model" RAY; probably built in the late 1930's or early 1940's. This engine has several improvements incorporated in the design, notably a "modern" magneto with magnets on the flywheel.

I acquired this engine from a contact I made in a Yahoo engine interest group. I provide a "before" picture of this engine as well as pictures of it after it's renovation.
