Abstract
A golf-club and golf-ball testing apparatus, having a crank arm driven by a main drive shaft, drives a club swinging arm through a secondary drive shaft supported by bearings on the end of the crank arm and turned by a planetary gear which meshes with teeth in a fixed gear concentric with the main drive shaft. The club swinging arm is connected to the secondary drive shaft by a short block, and the club is connected to the end of the swinging arm by a gripping member that is caused to rotate from an adjustable initial position so that the shaft is rolled through about 180.degree. during a full swing. The short block is coupled to the secondary drive shaft by resilient material to absorb shocks between the swinging arm and the crank arm.

Apparatus for swinging a golf club to strike a golf ball for the purpose of testing the club or the ball, said club having a shaft with a grip at one end, said apparatus comprising
- a golf club swinging arm,
- a main drive shaft and means for driving said shaft through a predetermined angle with selected energy,
- a crank arm of selected length secured to said main drive shaft to be pivoted by said main drive shaft through said predetermined angle in a plane normal to said drive shaft,
- a fixed gear concentric with said main drive shaft,
- a secondary drive shaft parallel to said main drive shaft and supported by bearings at the free end of said crank arm,
- a planetary gear keyed to said secondary drive shaft and meshing with said fixed gear,
- means for securing said golf club swinging arm to said secondary drive shaft for driving said swinging arm through an angle greater than said predetermined angle and in an inclined plane normal to said secondary drive shaft, and
- pivotal means connected to the end of said club swinging arm securing said golf club at said grip to the end of said swinging arm.
