Abstract
Abstract The spherical shaped probe for a coordinate measuring machine is modified by incorporating a pair of rods mounted in recesses formed in the center of the sphere at a side and bottom to define a straight edge whose measurement is equal to the sphere's radius measured at the tangent to the vertical and horizontal diameters. Both rods being mounted at right angles relative to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
A probe for a coordinate measuring machine that takes measurements in three dimensions and responds to computer calculated signals, the contact portion of said probe being generally spherically shaped, the improvement comprising an elongated bar-like element mounted in a vertical recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 90° quadrant relative to the vertical axis of the generally spherically shaped member.
Claim 2
Dependent Claim
93 words
A probe for a coordinate measuring machine that takes measurements in three dimensions and responds to computer calculated signals, the contact portion of said probe being generally spherically shaped, the improvement comprising an elongated bar-like element mounted in a vertical recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 90° quadrant relative to the vertical axis of the generally spherically shaped member.
Claim 3
Dependent Claim
67 words
A probe as in claim 1 including another bar-like element mounted in a horizontal recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 180° quadrant relative to the vertical axis of the generally spherically shaped member.
Claim 4
Dependent Claim
31 words
A probe as in claim 1 or 2 wherein said bar-like elongated member is an elongated rod extending almost the length equal to the diameter of said generally spherically shaped member.
Claim 5
Dependent Claim
160 words
A probe for a coordinate measuring machine that takes measurements in three dimensions and responds to computer calculated signals, the contact portion of said probe being generally spherically shaped, the improvement comprising an elongated bar-like element mounted in a vertical recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 90° quadrant relative to the vertical axis of the generally spherically shaped member, another bar-like element mounted in a horizontal recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 180° quadrant relative to the vertical axis of the generally spherically shaped member, and being perpendicular to said bar-like member.
Claim 6
Dependent Claim
160 words
A probe for a coordinate measuring machine that takes measurements in three dimensions and responds to computer calculated signals, the contact portion of said probe being generally spherically shaped, the improvement comprising an elongated bar-like element mounted in a vertical recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 90° quadrant relative to the vertical axis of the generally spherically shaped member, another bar-like element mounted in a horizontal recess formed in the center of said generally spherically shaped member and the transverse dimension of said bar-like member being such that its outer surface lies tangent to the outer removed surface of the generally spherically shaped member at the 180° quadrant relative to the vertical axis of the generally spherically shaped member, and being perpendicular to said bar-like member.
Claim 7
Dependent Claim
52 words
A probe as in claim 4 wherein said bar-like elongated member is an elongated rod extending almost the length equal to the diameter of said generally spherically shaped member and said other bar-like elongated is another elongated rod extending almost the length equal to the diameter of said generally spherically shaped member.
