8125 State Street, South Gate, California
James H. Lawlor of 8125 State St., South Gate, California, has re-activated his four cylinder uniflow engine that he introduced in 1948. He has constantly strived to build a better engine, with a few new innovations added. This engine can be used in many applications too numerous to mention.
There is a real world need for a steam farm tractor, and his present endeavor has been applying his unit to a No. 20 Cockshutt farm tractor. This make of tractor uses the chassis construction that proves best to convert from gasoline operation to steam.
This steam unit will apply to other makes of tractors we hope to work on in the near future, but for the present he intends to supply the necessary parts to the best of his ability to any one that wishes to build his own steam plant.
He operates a small shop, doing most of the work himself. He hopes to contact some manufacturer that can really produce these units in mass production.
He has built several types of steam controlled units, automatic, semi-automatic and manual. He finds the manual type to be best for the farmer.
This steam tractor is a manual operated type with a water level steam generator, hydrostatic tested for 3000 P. S. I. Operating pressure 500-1000 P. S. I. with an A. S. M. E. authorization certificate.
