Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
199 words
An apparatus for measuring the dynamic and dead weight of a golf club comprising, a housing having an opening in the top thereof, a bracket extending upwardly from said housing at a point spaced longitudinally of said housing from said opening, a flange at the upper end of said bracket, a lower surface forming a part of said flange, an electric weight measuring device in said housing, a standard having its lower end connected to said weight measuring device and extending upwardly through said opening, a fulcrum support affixed to the upper end of said standard and having a cradle transverse to said housing, a knife edge member defining one side of said cradle and parallel thereto, said edge member terminating in a plane spaced below the plane of said lower surface of said flange a distance equal to the diameter of the grip of said golf club whereby a golf club can be secured to said apparatus by placing the grip end under said lower surface and an intermediate portion of said shaft on said edge member and the moment measured by said device, and means on said housing to convert the moment measurement into a numerical readout.
Claim 2
Independent Claim
199 words
An apparatus for measuring the dynamic and dead weight of a golf club comprising, a housing having an opening in the top thereof, a bracket extending upwardly from said housing at a point spaced longitudinally of said housing from said opening, a flange at the upper end of said bracket, a lower surface forming a part of said flange, an electric weight measuring device in said housing, a standard having its lower end connected to said weight measuring device and extending upwardly through said opening, a fulcrum support affixed to the upper end of said standard and having a cradle transverse to said housing, a knife edge member defining one side of said cradle and parallel thereto, said edge member terminating in a plane spaced below the plane of said lower surface of said flange a distance equal to the diameter of the grip of said golf club whereby a golf club can be secured to said apparatus by placing the grip end under said lower surface and an intermediate portion of said shaft on said edge member and the moment measured by said device, and means on said housing to convert the moment measurement into a numerical readout.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1 wherein said edge member and said bracket are spaced apart a distance at which the action of said club supported thereby simulates the action of said club in actual use.
Claim 4
Dependent Claim
12 words
The apparatus of claim 2 wherein said distance is approximately eight inches.
