Model: 113 Old Oaken Bucket
This is the first known method of raising water from a well of no considerable depth. Use is made of a lever of the first type (See first model on No. 2). The rock or counter balance attached to the boom assists in lifting the bucket because it equals about one-half of the weight to be raised.
[Virginia Downward & William M. Clark, 1930]

[Editor’s Note: This mechanism is not unlike a slider-crank linkage, where the bucket acts as the sliding piston and the cable serves as the connecting link. FCM]
