Anthony A. Coppola, Esq.
On June 7, 1988 the U.S. Patent and Trademark Office issued U.S. Patent No. 4,748,745 entitled, “Chain Saw Brush for Cleaning Saw Cuts” to Richard G. Woodbridge of Princeton, New Jersey.
You might think that a chain saw brush seems like a pretty insignificant invention and unworthy of a TWIPH – and normally you might be correct.
However, the noteworthy tidbit about the ‘745 Patent? Richard G. Woodbridge was 11 years old when the Patent issued!
The chain saw brush the youngster designed was used to clean out sawdust accumulating in chain saw cuts to avoid sawdust build-up that otherwise caused the chain saw to jam. The brush disclosed in the ‘745 patent is stationary, mounted on two brackets above to the chain saw blade, and is used by turning the chain saw upside down and moving the bristles through the saw cut. Woodbridge claimed to be inspired by the bristles along the back of windshield snow scrapers.

As the son of patent attorney Richard C. Woodbridge, the boy admittedly had help in adding an optional brush agitator that would tranfer vibrations from the chain to the brush to improve the sawdust removal rate.
It just goes to show you that anyone can make intellectual property history!
