| November/December 1961


The data on the opposite page is the result of the economy tests runs of steam traction engines tested at Montpelier, Ohio last June.

As in former years, the testing was done on the original A. D. Baker Co. Prony friction brake. This brake was borrowed from the Baker Co. in 1945 and when Mr. Baker attended his first thresher reunion at the Blaker Farm several years later and saw the interest that was shown, he gave it to the association.

Compared with the 1960 tests that were published in the Jan.- Feb. 1961 issue of IRON MEN ALBUM, it will be noted that they vary somewhat. A good simple counter flow engine should use from 32 to 36 lbs. of water per hp. hr.

The Advance catalogue states that their new engines will develop one horsepower per hour on 34 lbs. of water. Last years tests shows John Holp of near Brookville, Ohio with his nice 20-60 hp. Advance engine did it on 32.54 lbs. of water.

I assumed the Baker uniflow engine was as economical as a good Woolf compound engine, but the average of our tests did not prove it. Also on the average, the boilers with long tubes proved the most economical.
