Absolutely Mad Inventions

Download or read book Absolutely Mad Inventions written by Alford Eugene Brown and published by Courier Corporation. This book was released on 1970 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is the world ready for a tie pin that can be eaten in case of sudden hunger? Or a railroad train that avoids collisions by climbing on top of the opposing train? Or a privy seat that will throw to the ground anyone who tries to stand on it? Or a man's hat that will automatically tip itself in greeting when the wearer nods slightly? All these--and more--are inventions on which patents have actually been granted by the United States Patent Office, and which authors Brown and Jeffcott have unearthed for our edification, entertainment, wonder, and at times bewilderment.
