Byron Jones’ Jeep Patent
We all know Karl Probst can be credited with inventing the WWII Jeep. And yet, Col. Byron Jones filed an application to be certified as the inventor on behalf of the Army, covering “various aspects of the design and construction of the Jeep body.”
Karl Knight Probst was an American freelance engineer and automotive pioneer who is credited with drafting the design drawings of the first prototype of the Bantam Reconnaissance Car, the first "Jeep," in 1940. And yet, Byron Quinby Jones applied for — and received — a patent for a Jeep-like body in 1942.
Byron Quinby Jones (April 9, 1888 – March 30, 1959) was a pioneer aviator and an officer in the United States Army. Jones began and ended his career as a cavalry officer, but for a quarter century between 1914 and 1939, he was an aviator in the various organizations that were the Army’s air arm.
Even though the first major production series of the quarter-ton truck known as the “Jeep” had been of the design submitted by Willys, the Army had a strong interest in establishing ownership of the design. Jones filed an application to be certified as the inventor on behalf of the Army, covering “various aspects of the design and construction of the Jeep body” with the United States Patent Office on October 8, 1941, stating in the application that
“The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes without the payment of any royalty thereon.”

Jones the Inventor
Jones was himself an inventor. The March 1944 issue of Popular Science described his proposal for a lightweight amphibious tank, and he was issued several patents:
- a steering by driving mechanism, granted June 17, 1941
- a multiple differential, granted November 3, 1942
- an armored vehicle body, granted September 28, 1943
- possibly a diaphragm muffler, granted March 22, 1927 to a Byron Q. Jones of Washington, D.C.
- possibly a wind indicating airways beacon, granted June 27, 1933 to Byron Q. Jones of Washington, D.C.
In all the above patent applications (except that of the muffler), Jones included the stipulation that, "The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon."
