Abstract
Abstract Apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a cracking plane. The apparatus has (a) a fixture assembly for holding one internal side of the bearing stationary, and (b) structure for fracturingly pulling a second internal side of the bearing away from the one internal side along a track in a direction substantially perpendicular to the cracking plane.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
An apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a predetermined cracking plane, comprising: (a) a fixture assembly for holding one internal side of said bearing stationary, said one internal side being on one side of said cracking plane; and (b) means for fracturingly pulling a second internal side of said bearing away from said one internal side along a track in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
Claim 2
Independent Claim
85 words
An apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a predetermined cracking plane, comprising: (a) a fixture assembly for holding one internal side of said bearing stationary, said one internal side being on one side of said cracking plane; and (b) means for fracturingly pulling a second internal side of said bearing away from said one internal side along a track in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
Claim 3
Independent Claim
96 words
An apparatus for fracturing an annular bearing support, fracturable at room temperature, said support having stress risers to initiate cracking along a predetermined cracking plane, comprising: (a) a fixture assembly for holding one internal side of said bearing support substantially stationary, said one internal side being on one side of said cracking plane; and (b) means for fracturing by pulling a second internal side of said bearing support away from said one internal side along essentially a straight path in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
Claim 4
Independent Claim
96 words
An apparatus for fracturing an annular bearing support, fracturable at room temperature, said support having stress risers to initiate cracking along a predetermined cracking plane, comprising: (a) a fixture assembly for holding one internal side of said bearing support substantially stationary, said one internal side being on one side of said cracking plane; and (b) means for fracturing by pulling a second internal side of said bearing support away from said one internal side along essentially a straight path in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
