In the past, I have written a couple of articles about the history of the Fuller & Johnson Company (F & J), Madison, Wisconsin and the engines they built. Many of you know that I got the records of the F & J Company several years ago. Since then I have tried to find out all I can about the history of the company and their engines by studying the records, old books and talking with former employees.

This article is about what I have been able to gather together regarding the air-cooled Farm Pump Engine, (FPE). The FPE was, I'm sure, the engine that F & J was best known for, and they built more of these than any other single model. This engine is unusual for the fact that they run in the opposite rotation of most engines. They are different also, because they have just one flywheel, use the auxiliary exhaust port system, and are unusual looking.

The FPE came out in 1909 and were built until 1952, with the same basic design. There were some minor changes made over the years, and I will explain these in this article.

Mr. Frank Winkley, who was chief engineer for F & J, designed and patented the FPE. For this he received $1 per engine that the company built. This may not sound like much for his efforts, but one has to remember the value of the dollar in these years and the fact that at one time F & J were building one hundred of these engines per day. This was a sizable income for Mr. Winkley.

The first type of the F & J Farm Pump Engine. Note the wood base, plain flywheel and that there is no battery box attached. Taken from a 1910 catalog.
