ABSTRACT:
A device which includes a frame supporting a lever arm for tiltable movement about a horizontal axis intermediate the ends thereof and, more particularly, to an improved apparatus for nullifying the effects of angular acceleration of such frame relative to its lever arm which comprises a counterweight and hanger means for suspending the counterweight between the frame and arm which cooperate with one another under the influence of inertial forces tending to angularly accelerate one relative to the other by generating an offsetting inertial force operative to maintain a condition of stable equilibrium therebetween.
