The method Adams originated was called the Lorythmic matching system. Using a 14" fulcrum point on his balancing scale, Adams designated the units of measurement from A to G in the alphabet with 10 incremental points between each letter.

Hence, this is the notation we are familiar with today of C9, D2, etc. Adams was awarded a patent for his Lorythmic scale concept, which was first used in clubmaking by Kenneth Smith Golf Company in 1926, which later produced the scale for use by other clubmakers in 1931.

The principal of swingweight was born as it expressed the weight of the entire club about a fixed point (14" from the butt end) and its relationship between the balance points of the club.
