I used to think how could transform this stationary steam engine, into one I could run on my o gauge layout, but of course it just was too big and bulky and used 115V, not a measly18V. Everything would have to be scaled down.
This was extracted from the patent:
"In order to more clearly bring out the important features of the invention, I shall give below the data about a typical toy locomotive made in accordance with the invention. The locomotive had a boiler 7" long and 1¾" diameter with the usual engines and other driving equipment. To heat the boiler there was mounted therein a helical coil, as shown in Figs. 2 and 3, made of pure nickel wire .0226 inches diameter, the coil having ½" diameter, about 6 length, and approximately 2 ohms resistance at room temperature. When connected to the 25 volt terminals of an ordinary 110 to 25 volts Lionel type K transformer, the coil drew about 12 amperes while immersed in the water, the current going down to less than 5 amperes when the boiler became empty, without becoming excessively hot. Unusual results are thus obtained by using an exposed immersion heater in a boiler at the low voltage range of about 25 volts."
