Inventions
In the 1920s Pullin developed various helicopter engine patents and in the 1940s he developed the Powerwheel, a rotary engine in the hub of a motorcycle wheel, a rotating single-cylinder engine known as a one-lunger. This consisted of just the cylinder and a clutch which could be engaged and disengaged, with a simple drum brake. The invention never entered production but is credited as an important step in rotary engine development.
His sister was married to Stephen Leslie Bailey, a then prominent engineer at Douglas Motorcycles and many of his patents were filed under the name of that company.

Famous quotes containing the word inventions:
“Young children constantly invent new explanations to account for complex processes. And since their inventions change from week to week, furnishing the “correct” explanation is not quite so important as conveying a willingness to discuss the subject. Become an “askable parent.””
—Ruth Formanek (20th century)
“The treasury of America lies in those ambitions and those energies that cannot be restricted to a special, favored class. It depends upon the inventions of unknown men; upon the originations of unknown men, upon the ambitions of unknown men. Every country is renewed out of the ranks of the unknown, not out of the ranks of those already famous and powerful and in control.”
—Woodrow Wilson (1856–1924)
“I shall not bring an automobile with me. These inventions infest France almost as much as Bloomer cycling costumes, but they make a horrid racket, and are particularly objectionable. So are the Bloomers. Nothing more abominable has ever been invented. Perhaps the automobile tricycles may succeed better, but I abjure all these works of the devil.”
—Henry Brooks Adams (1838–1918)
