The Chieftain mentions a 1934 patent on torsion bar suspension held by Gladeon Barnes?  It makes me wonder if he watched my video on that particular topic three weeks ago.   :D

 

 

Barnes had a number of patents and fingers in a lot of things.

 

"The Army recognized Colonel Barnes in 1920 as its authority on “all matters relating to the design and manufacture of Railway Artillery in the Office of the Chief of ordnance.”  He was also a prolific inventor of other ordnance items, including vehicle suspension designs, armored vehicle track, guns, gun carriages, and vehicles. By 1940, he had 31 patents for his work with Ordnance, all of which bore the caveat “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.” Barnes would receive another two patents postwar for a heavily armored two-man tank, which was a development of the two-man tank he conceived of at the Army War College.

 

Colonel Barnes’ was instrumental in the development of one important innovation in the field of armored vehicles in concert with George M. McCann in 1933. In early 1934, they filed for the first of several related patents for a torsion bar suspension system suitable for tracked armored vehicles. Of course, torsion bar suspension was not particularly new, British Leyland had produced an automobile with torsion bar suspension in 1921 and Ferdinand Porsche had applied for a German patent for the system he used in his auto designs, but it was a relatively innovative technology for tanks. In 1934, the Swedish company AB Landswerk designed a light tank with torsion bar suspension that began production for export in 1937 and later models of the German Panzer III built in 1939 used torsion bars.

 

The torsion bar system duplicated the smooth ride of the suspension system designed by J. Walter Christie (see below), but without the Christie suspension’s habit of shedding tracks in tight turns. Torsion bars also did not compromise usable space inside the hull of the vehicle, since they ran longitudinally on the bottom of the hull instead of mounting the suspension components inside the hull wall as in the Christie system. However, torsion bars were as expensive to manufacture as the Christie system and were more expensive than the simple and robust vertical volute suspension developed by Ordnance during the 1930s. The result was, as Brigadier General John K. Christmas –who at the time was a captain assisting Barnes and McCann—later put it, “I was never in the position to get funds for its development until the winter of 1942-3.”  It would be ten years before the U.S. Army deployed armored vehicles using torsion bar suspension." (from my manuscript)

 

He was also the principal designer of the 75mm T3 Gun and Carriage, which began as the 75mm Gun M1 (M1923E1) on Carriage T2 and T3 in May 1929. Coincidentally, that gun progressed through various iterations as a "universal gun" (dual purpose field and AA gun), through the 75mm Gun T6, which was the basis for the 75mm Gun M2 and M3 as used in the Medium Tank M3 and M4.

Scrolling through the comments, I saw at least one other Tanknetter comment. The rest must have dismissed the question as gibberish. :P Or was THAT you?

Seems to be an entirely anglo-sphere centric piece of tank folklore.

The canned apricots in C-rations were horrible.  Nobody liked them and you couldn't trade them away.

Eating them was seen as the ultimate form of bad luck.  I never heard a good reason for it, I had one TC who talked about some tank crew being killed in Vietnam after their loader ate them.  All I know is that my tc lost his shit when I actually ate them on my first field op.  He blamed our tank catching fire on it.  I think the actual cause was the lit cigarette he flipped away that blew into the bustle rack and landed in the folds of the tarp. In any case I never ate them again in the field.
