Roto Rooter

In 1933, Samuel Blanc created a funny-looking sewer cleaning machine from a 1/6 HP Maytag washing machine motor, roller skate wheels and 3/8" cable to turn the blades. The device used a combination of special blades or "knives" to cut tree roots out of sewer lines. No digging was required. A year later, Sam's wife Lettie christened the prototype the "Roto-Rooter."
