Oil filter crusher

An oil filter crusher, comprising:

• a threaded drive screw having a shaft extending between first and second ends and a drive head at said first end;
• an elongated frame having a first triangular plate at a first end, a second triangular plate at a second end, and three shafts extending between said first and second triangular plates, said frame having a threaded drive opening engaging said drive screw at said first end;
• and
• a ram assembly at said second end of said drive screw, said ram assembly including a third triangular plate substantially aligned with said first and second triangular plates and having openings engaging said three shafts, said ram assembly moving toward and away from said second end of said frame in response to rotation of said drive screw with respect to said frame.

An oil filter crusher, comprising:

• a threaded drive screw having a shaft extending between first and second ends and a polygonal drive head at said first end;
• an elongated frame having a first triangular plate at a first end, a second triangular plate at a second end, and three shafts extending between said first and second triangular plates, said frame having a threaded drive opening engaging said drive screw at said first end;
• a ram assembly at said second end of said drive screw, said ram assembly including third and fourth triangular plates substantially aligned with said first and second triangular plates, each of said third and fourth triangular plates having openings engaging said three shafts, said ram assembly moving toward and away from said second end of said frame in response to rotation of said drive screw with respect to said frame;
• and
• wherein said oil filter crusher does not include any actuator for rotating said drive screw.

An oil filter crusher, comprising:

• a threaded drive screw having a shaft extending between first and second ends and a drive head at said first end;
• an elongated frame having first and second ends, a threaded drive opening engaging said drive screw at said first end, and a retainer at said second end for disposing an oil filter therein, said retainer having a drain for collecting residual oil extracted from said filter;
• and
• a ram assembly, said ram assembly including a thrust bearing assembly coupling said ram assembly to said second end of said drive screw, said ram assembly moving toward and away from said second end of said frame in response to rotation of said drive screw with respect to said frame.
