Invents Hourmeter to Time Hops (Sep, 1930)
This was the cutting edge in aviation technology until the introduction of the minutemeter in WWII.
Invents Hourmeter to Time Hops
THROUGH an electrical contact attached to the landing gear, the recently invented hourmeter timing device records trip and total flying time the moment the plane leaves the ground. The same contact stops the clock when the landing is made. Spreading and contracting of the landing gear actuates the electrical circuit. Current is supplied by two dry cells, or from the ship’s battery.
Aeronautical experts declare that this instrument will fill in one of the gaps of aviation.
