ABSTRACT:
The assembly is for shearing rod sections with a movable cutter carriage carrying a shearing blade between a resting position and a shearing position. A reciprocating impact head is used to drive the cutter carriage. The impact head is moved into contact with an adjacent end of the cutter carriage to effect motion of the cutter carriage to the shearing position. The cutter carriage is biased toward the impact head and the resting position to effect the return stroke motion of the cutter carriage. The contact of the impact head with the adjacent end of the cutter carriage is broken on completion of the return stroke to draw the impact head a predetermined distance back to a starting position from which the impact head is ready to strike the adjacent end of the cutter carriage with considerable momentum upon the starting of the next shearing cycle.
