Gift o' Gab (1917)

Tom Bain was born with a tongue so glib that his parents, early in his career, predicted he would be a second Chauncey Depew. In college it developed until he was capable of selling Liberty Bonds in a poor house. But Tom was ambitious to be an inventor and so built a tunneling machine that "would start at one side of a mountain and propel itself through to the other without man's assistance." His gift of gab sold the rights to the machine to a big manufacturing firm, but they soon found it worthless and instead of building machines, Tom was placed on the payroll as a salesman. And then, after an exciting series of adventures, Tom finally wins the hand of Peggy, whom he had met and courted in his college days. The wedding occurs in a hospital where the couple meet accidentally as patients.
