Method for custom fitting golf clubs
First Claim
1. A method of custom designing a golf club for a particular individual golfer which will give the maximum distance of ball travel, said method comprising the steps of:
- a. providing means for adjusting the club head weight, lie angle, and golf club shaft length used by the particular individual golfer during the practicing of this method;
b. providing means for measuring the velocity and loft angle of golf balls hit by the particular individual golfer during the practicing of this method;
c. hitting a series of golf balls with a golf club the club head weight of which is a predetermined minimum and calculating the average velocity of said golf balls;
d. hitting another series of golf balls with a golf club the club head weight of which is incrementally greater than in the previous step and calculating the average velocity of said golf balls;
e. continuing to hit further series of golf balls with golf clubs having club head weights which are incrementally greater than in the previous step and calculating the average velocity of each series until a first maximum velocity is established;
f. calculating the swing weight of the golf club which produced said first maximum velocity;
g. hitting a series of golf balls with a golf club having a swing weight producing said first maximum velocity and a shaft the length of which is a predetermined minimum and calculating the average velocity of said golf balls;
h. hitting another series of golf balls with a golf club having a swing weight producing said first maximum velocity and a shaft length of which is incrementally longer than in the previous step and calculating the average velocity of said golf balls;
i. continuing to hit further series of golf balls using golf clubs having a swing weight producing said first maximum velocity and shafts the lengths of which are incrementally larger than in the previous step and calculating the average velocity of each series until a second maximum velocity is established;
j. hitting a series of golf balls with a golf club having a swing weight producing said first maximum velocity and a shaft length producing said second maximum velocity and a predetermined lie angle and calculating the average velocity of said golf balls;
k. continuing to hit further series of golf balls using golf clubs having a swing weight producing said first maximum velocity and a shaft length producing said second maximum velocity and a lie angle which is incrementally different than in the previous step and calculating the average velocity of each series until a third maximum velocity is established; and
l. calculating the average lift-off angle of a series of balls hit with a golf club having a swing weight producing said first maximum velocity, a shaft length producing said second maximum velocity, and a lie angle producing said third maximum velocity and determining from said average lift-off angle the optimum loft angle for the particular individual golfer.

Abstract
A device utilizing a system of photobeam measurers to detect the speed imparted to a golf ball by a golfer that is utilized with a golf club of adjustable weight and design for determining the optimum club design for a particular individual golfer being tested. The device is used in a method of custom-fitting golf clubs in which the proper swing weight, length, and lie and loft angles of a golf club are determined. The method of fitting consists in a series of steps in which a golfer hits a series of balls through the photobeams with a club which is incrementally lengthened, weighted, and has its lie angle adjusted. The adjustments are made until the point is reached at which the golfer imparts maximum velocity.
