Patent of the Month: Higgins boats

Written on: June 6, 2014 | 0 Comments

Today marks the 70th Anniversary of the D-Day invasion. To commemorate this anniversary, this month’s patent is Andrew Higgins’s landing boat. It is dated February 15, 1944, less than four months before D-Day.

LCVPs–or Higgins boats, as they are now commonly known –transported troops from the 1st Infantry onto Omaha Beach. They could each carry 36 combat-equipped infantrymen or 8,000 pounds of cargo. In all, 23,398 Higgins boats were produced during the war.

During World War II, the South Side of Chicago was home to one of the largest war plants in the country, used by Dodge-Chrysler to build bomber plane engines. After the war, Preston Tucker leased two of the buildings to build his “Torpedo” car. This site is now the home of the National Archives at Chicago! Our National Archives Education team shares the full story on their Facebook page.

Here are the patent drawings for Tucker’s “Torpedo” car:

Patent of the Month: Eli Whitney’s Cotton Gin

When I was a kid growing up in Beverly, MA, every morning I would walk by the site of the cotton mill visited by George Washington. That mill, the Beverly Cotton Manufactory, even predated Eli Whitney’s cotton gin, which was patented 220 years ago today!

Patent of the Month: Still Design, 1808

Written on: February 26, 2014 | 1 Comment

Stills similar to the one represented in this drawing were used to make distilled liquors and were commonly used in America during the early 19th-century. And their “descendants” are still being found in the mountains of rural America!

A preview of an exhibit planned for 2015 here at the National Archives: “Spirited Republic.”
