Patent ID: 8201337

Claim:
A reciprocating cutting tool configured for orbital cutting, comprising: a housing; a power source disposed in said housing; a main linkage connected to said power source and to a blade for driving the blade in a vertically reciprocating motion; a swivel bracket connected to a foot plate and disposed to exert a force to a rear edge of the blade wherein said swivel bracket includes a holder configured for mounting to said foot plate, and a rocker member pivotally joined to said holder, the rocker member having a blade engaging end for engaging the rear of the blade to create an orbital motion, and a landing end opposite the blade engaging end, said landing end being biased toward said housing, a reciprocating pusher engaging said landing end to pivot the blade engaging end in an arc against the blade, causing an orbital action; a swivel linkage driven by said main linkage for exerting an eccentric force on said swivel bracket for creating said force on the blade, wherein said swivel linkage includes said reciprocating pusher that is driven by said main linkage along a longitudinal axis which parallels the movement of the blade; and said foot plate being connected to said housing and including a portion in operational proximity to the blade.
