Portable device for manipulating carpet tack strip

A device for retrofitting a power tool having a reciprocating piston, the device comprising:

• (a) a hollow housing in the shape of a cylindrical tube that has a distal end and a proximal end;
• (b) a connecting means attached to the proximal end of the hollow housing, said means enabling attachment of the device to a reciprocating piston of a power tool;
• (c) a hammer bar for reciprocal movement within the housing and having a first blunt end for hammering;
• (d) a cutting bit comprising a sharp end and a second blunt end, the second blunt end having dimensions whereby said cutting bit fits snugly on the first blunt end of the hammer bar;
• (e) an alignment sleeve;
• (f) a first reciprocating spring located inside the hollow housing and operatively connecting the hammer bar to the hollow housing;
• (g) a second reciprocating spring located inside inside the hollow housing and operatively connecting the alignment sleeve to the hollow housing;
• (h) a swivel means for connecting the cutting bit to the alignment sleeve wherein the swivel means comprises an elastic arm and a swivel joint, the swivel means allowing for pendulum-type motion whereby the cutting bit can be in an operative reciprocating position and in an inoperative non-reciprocating position at different times, the operative position being when the cutting bit fits snugly on the first blunt end of the hammer bar.

An apparatus for retrofitting an air hammer comprising:

• (a) a hammer bar comprising an elongated solid metal cylinder having a proximal end and a distal end, the cylinder having a flange near the proximal end;
• (b) an alignment sleeve comprising a hollow metal cylinder having a primary end and a secondary end, both ends having an aperture that allows for reciprocal movement of the hammer bar;
• (c) a housing unit comprising an elongated hollow metal cylinder having a first end and a second end, both ends having an aperture that allows for reciprocal movement of the hammer bar;
• (d) a first attachment means for flexibly connecting the hammer bar to the housing unit, said first attachment means being a first flexible spring system;
• (e) a second attachment means for flexibly connecting the alignment sleeve to the housing unit, said second attachment means being a second flexible spring system;
• and
• (f) a third attachment means for connecting the housing unit to the air hammer, said housing unit being attachable to the air hammer at the first end of the housing unit, the third attachment means having a member selected form the group consisting of allen screws, a threaded barrel, fast clips and clamping means.
