He also worked on a type of motor, very light, and modeled after one his father had recently patented.
Then a new idea came to Tom in regard to the shape of his aeroplane, and he worked several days drawing the plans for it. It was a new idea in construction, and he believed it would give him the great speed he desired.
"But I'd like dad to see it," he said. "As soon as he's well enough I'll go over it with him."
That time came a week later, and with a complete set of the plans, embodying his latest ideas, Tom went into the library where his father was seated in an easy-chair. Dr. Gladby had said it would not now harm the aged inventor to do a little work. Tom spread the drawings out in front of his father, and began to explain them in detail.
"I really think you have something great there, Tom!" exclaimed Mr. Swift, at length. "It is a very small monoplane, to be sure, but I think with the new principle you have introduced it will work; but, if I were you, I'd shape those wing tips a little differently."
"No, they're better that way," said Tom pleasantly, for he did not often disagree with his father. "I'll show you from a little model I have made. I'll get it right away."
