Working Steam Roller Model Pulls Two Persons On Cart
STANDING only ten and three-quarter inches high with an overall length of 20 inches, a working scale-model of a steam roller constructed by C. Hollandtrick, of Lincolnshire, England, is claimed to be powerful enough to haul a small trolley seating two persons. The model weighs 26 pounds and was constructed at a cost less than five dollars. A coal fire being impractical on such a small model, the water is heated by means
of a paraffin burner to create a steam pressure of approximately 40-45 pounds per square inch in the broiler.
