August 7th is National Purple Heart Day. The Purple Heart was first created on this day in 1782 by the commander-in-chief of the Continental Army, General George Washington.
Then known as the Badge of Military Merit, it was awarded to 3 Revolutionary soldiers in 1783. Take a moment today to remember all the brave servicemen and women who have been wounded or killed while serving in our armed forces.

The reduction gears and steam turbines under construction at the General Electric Plant, circa March 1942.
Based on the date and the fact USS Iowa (BB-61) and USS Missouri (BB-63) were the only Iowa Class Battleships to receive General Electric gears and turbines, these are most likely for USS Missouri.
There are four sets of double reduction cross-compound geared turbines, with each turbine set driving a single shaft. “They offered almost 10-1 reduction to allow the turbines to run at much higher and more efficient rpm. These are some of the most critical components of the powerplant and one of the things which allowed long ranges in US battleships."
A man is shown deburring the edges of teeth with a file.
Note that they are double helix which eliminates axial thrust while providing the quieter running and increased strength of helically cut gears.
