Abstract:
A device usable for calibrating a torque wrench with a ratchet head which is adjustable to provide a range of torque settings, which comprises;a frame;a beam member pivotally connected to said frame at a pivot axis;a weight coupled to the beam member and movable along a path having a component substantially parallel to the beam member for setting a desired torque level;an arm member having upper and lower ends;a gear connected to said beam at said pivot axis;said arm member having a gear-engaging surface for rotating said gear, the arm member pivotally attached to the frame; anda projection coupled to said arm member for receiving the ratchet head of the torque wrench so that rotation of said projection rotates said arm and said gear, lifting said beam member if said ratchet head is adjusted to a torque setting at least equal to said desired torque level.
