Claim 0:
1. In combination, a machine vise and a vise jaw insert spring-loaded waste shield and cleaning aid, said machine vise having:
a pair of opposed jaws each defining a contact face in a vertical plane; and
a linear actuator reciprocating at least a first one of said pair of opposed jaws relative to a second one of said pair of opposed jaws;, said vise jaw insert spring-loaded waste shield and cleaning aid having:
a fixed block defining a vertical planar first surface engaging said contact face of said first one of said pair of opposed jaws, and a horizontal planar second surface extending from said fixed block first surface, said fixed block second surface defining a covering over said machine vise actuator configured to support work pieces during a machining operation and configured to shield said machine vise actuator from machining waste generated during said machining operation;
a moving block defining a vertical planar first surface engaging said contact face of said second one of said pair of opposed jaws, and a horizontal planar second surface extending from said moving block first surface, said moving block second surface defining a covering over said machine vise actuator configured to support work pieces during said machining operation and configured to shield said machine vise actuator from machining waste generated during said machining operation;
a linear bearing coupling said moving block to said fixed block and defining a first axis of reciprocation of said moving block relative to said fixed block;
a variable-width gap extending between said fixed block and said moving block along said first axis of reciprocation;
a spring applying a spring force along said first axis of reciprocation to each of said fixed block and said moving block, said spring force configured to secure said fixed block first surface to said contact face of said first one of said pair of opposed jaws through a range of reciprocating motion by at least said first one of said pair of opposed jaws relative to said second one of said pair of opposed jaws, said spring force also configured to secure said moving block first surface to said contact face of said second one of said pair of opposed jaws through said range of reciprocating motion, and said spring force configured to tend to separate said fixed block from said moving block; and
a blocking flange unitary with and extending from said fixed block covering said variable-width gap between said fixed block and said moving block and thereby configured to shield said machine vise actuator from machining waste.
