US Patent 7351161 Scientifically adaptable driver

An improved golf ball driver has a first weight positioned within the clubhead of the driver, and a first means for adjusting the first weight in a generally vertical direction within the clubhead, that is, from top to bottom thereof. The improved driver also has a second weight positioned within the clubhead, and a second means for adjusting the second weight in a generally horizontal direction within the clubhead, that is from the heel to the toe thereof. Adjusting the weights allows a golfer to eliminate natural swing problems and/or to make a desired change in the flight pattern of a golf ball when it is struck by the driver.
