Abstract
A recoil auger enables holes to be drilled by using only straight line motions of a person's hand, arm, and shoulder. The recoil auger is comprised of a recoil drive system connected to an output shaft, which in turn is connected to an auger. The recoil drive system has a recoil mechanism that imparts unidirectional rotation to the auger in response to bidirectional rotation of the recoil mechanism. The recoil mechanism includes a clutch bearing to unidirectionally rotate the auger. The recoil drive system has a handle that the person grasps during operation. Operation is achieved by pulling a rope wound around a rope wheel. A recoil spring rewinds the rope after a pulling motion. Multiple recoil mechanisms assembled to the output shaft and one or more suitable handles enable more than one person to operate the recoil auger at the same time.
