Marine Engine Information in The Motor Vehicle Manufacturers Association Patent Library, Detroit

By Staff

7964 Oakwood Park Court, St. Michaels, MD 21663

The Motor Vehicle Manufacturers Association (MVMA) maintains a
Patent Library at their offices in the Albert Kahn Building in
Detroit. There are boxes of literature on many subjects: brakes,
electrical, bodies, transmissions, engines, etc. The literature is
preserved for patent reasons, in case some item can show prior use
of an idea. The boxes are clean and well-labeled, though the engine
boxes are rather scattered. The librarian is James Wren; I found
him very helpful. They are not staffed to respond to letters or
phone calls, but anyone may visit the library and use it.

Each box contains literature for a period of one to three years.
Within each box, literature is divided into specific years by
folders. The ‘engine’ boxes contain literature on car,
truck, tractor, and marine engines. I took notes on only the marine
engines except for a few others that were of special interest to
me. The items below are catalogs unless otherwise noted. Markings
show that most items were picked up at trade shows.
