Ohio

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.

I was at the Baker Co. factory many times when they were building and testing steam traction engines. Their first high pressure light steam tractor was cross-compound and Mr. Baker told me he did not like the indicator cards from it, and they were looking for a more economical engine. I told him he would have to admit the Reeves cross-compound was a good engine.

John Albeck, one of their test house men, told me they acquired a 16 hp. Port Huron engine with Woolf Compound cylinders, and thoroughly rebuilt it, and in the test house, it developed one hp. hr. on 27 lbs. of water. That greater economy and cooler exhaust steam so their condenser radiator would be more efficient, caused the company to design and build a tandem-compound light steam tractor, and it would have been a great success had they been able to extract all of the cylinder oil from the condensed exhaust steam which was used to feed the boiler.
