"The Infernal Machine" is a horseless carriage, invented by Hoss Cartwright's friend Daniel Pettibone (Eddie Ryder). Attempting to obtain financing for Dan's creation, Hoss is turned down by everyone except a city slicker named Throckmorton (Willard Waterman). Once this glib stranger agrees to invest money in the carriage, everyone else in town follows suit. Alas, Throckmorton skips town with the cash, leaving Dan and Hoss holding the bag. Also appearing are June Kenney as Robin and Nora Hayden as Big Red. Written by Ward Hawkins and directed by Republic Studios stalwart William Witney, "The Infernal Machine" first aired April 22, 1961.
