Patent for a new and improved means for propelling railway cars. This design "relates to motive power for railway-cars, and the purpose thereof is to provide a simple combination of parts whereby each car may be impelled by a separate motor, the entire series throughout a line or train of cars being supplied with energy from a common source, whereby the full horse-power of a steam-boiler may be applied in a manner enabling it to be utilized to the greatest possible advantage and to the utmost extent" (lines 10-20).
