Abstract
Abstract Mounting apparatus for use with a hardness tester which includes a reciprocating penetrator for measuring hardness properties of the materials to be tested. The mounting apparatus may comprise: an elongated base member having parallel upper and lower flat surfaces and provided with a hole substantially midway between the ends thereof; substantially parallel elongated shoe members attached to the base member adjacent its lower surface for contact with the material to be tested; and components for removably attaching the hardness tester to the base member so that its penetrator is disposed in the base member hole for reciprocal movement therein.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
Mounting apparatus for use with a hardness tester of the type having a housing in which is carried a reciprocating penetrator for measuring hardness properties of materials to be tested, said mounting apparatus comprising: an elongated base member having parallel upper and lower flat surfaces, the edges of which are joined by first and second side surfaces and the ends of which are joined by first and second end surfaces, a hole being provided through said base member substantially midway between said first and second end surfaces and the axis of which is substantially perpendicular to said upper and lower surface; substantially parallel elongated shoe members attached to said base member adjacent said lower surface and near the edges thereof for contact with said material to be tested; and means for removably attaching said hardness tester housing to said base member so that said penetrator is disposed in said base member hole for reciprocal movement therein and for engagement with said material to be tested.
Claim 2
Dependent Claim
165 words
Mounting apparatus for use with a hardness tester of the type having a housing in which is carried a reciprocating penetrator for measuring hardness properties of materials to be tested, said mounting apparatus comprising: an elongated base member having parallel upper and lower flat surfaces, the edges of which are joined by first and second side surfaces and the ends of which are joined by first and second end surfaces, a hole being provided through said base member substantially midway between said first and second end surfaces and the axis of which is substantially perpendicular to said upper and lower surface; substantially parallel elongated shoe members attached to said base member adjacent said lower surface and near the edges thereof for contact with said material to be tested; and means for removably attaching said hardness tester housing to said base member so that said penetrator is disposed in said base member hole for reciprocal movement therein and for engagement with said material to be tested.
Claim 3
Dependent Claim
29 words
Hardness tester mounting apparatus as set forth in claim 1 including first and second weight members of substantially equal weight removably surmounted on each end of said base member.
Claim 4
Dependent Claim
48 words
Hardness tester mounting apparatus as set forth in claim 2 in which said first and second weight members are cylindrical and at least one end of which is provided with a coaxial hole for engagement with a corresponding pin member also engaging corresponding holes in said base member.
Claim 5
Dependent Claim
100 words
Hardness tester mounting apparatus as set forth in claim 1 in which said means for attaching said hardness tester to said base member comprises first and second stud members projecting upwardly from said upper surface of said base member on opposite sides of said hole therethrough and the axes of which are parallel to said hole axis, the housing of said hardness tester being attached to a frame member having holes at each end thereof for receiving the upper ends of said first and second stud members and by which said hardness tester is removably attached to said base member.
Claim 6
Dependent Claim
69 words
Hardness tester mounting apparatus as set forth in claim 4 in which one of said frame holes opens toward one side of said frame and the other hole opens toward the opposite side of said frame so that upon slight rotation of said frame member about the axis of said base member hole, said studs are disengageable from said holes for removal of said tester from said base member.
Claim 7
Dependent Claim
66 words
Hardness tester mounting apparatus as set forth in claim 5 in which the upper end of said stud members are provided with increased diameter portions, the diameter of which is greater than the diameter of said frame member holes, spring members being disposed about said studs between said base member and said frame member, biasing said frame against said increased diameter portions of said stud members.
Claim 8
Dependent Claim
98 words
Hardness tester mounting apparatus as set forth in claim 4 including an elongated weight increasing member having parallel upper and lower flat surfaces, a first hole substantially midway between the ends thereof, second and third holes on opposite sides of said first hole corresponding with said first and second stud members allowing said weight increasing member to be selectively surmounted on said base member, its lower surface engaging the upper surface of said base member and said stud members projecting through said second and third holes, said first hole being in coaxial registration with said base member hole.
Claim 9
Dependent Claim
31 words
Hardness tester mounting apparatus as set forth in claim 7 including first and second weight members of substantially equal weight removably surmounted on each end of said elongated weight increasing member.
Claim 10
Dependent Claim
66 words
Hardness tester mounting apparatus as set forth in claim 8 in which at least one end of each of said first and second weight members and both ends of said weight increasing member are provided with holes for corresponding engagement by pin members for proper weight distribution and registration of said first and second weight members relative to said base member and said weight increasing member.
