Abstract
Strain mechanism for bandmill using deadweight lever mechanism in which undesirable effects of inertia of counterweight and friction at knife edges are reduced. Rolling diaphragm air cylinder is used in one of three positions. In first position cylinder extends between arbor carrier arm and plunger tube and supplies portion of saw strain permitting lighter counterweight. In second position it extends between counterweight arm and plunger tube and eliminates counterweights. In third position counterweight is supported on counterweight arm by yoke supported by cylinder which resiliently mounts weight.
