Abstract
In a cutting machine having a reciprocating blade driven by a crank mechanism which includes an angularly balanced crank, the blade, the connecting rod which drives the blade and the connecting member which connects the blade to the connecting rod are dynamically counterblanced by a passive load, pair of connecting rods which drive the passive load in a direction opposite the direction of blade movement, and a pivoted link which cooperates with the pair of connecting rods to maintain the passiive load for movement in a predetermined path.
