DEFINITION

Classification: 73/1.39

Involving pendulum or impact:

(under subclass 1.38) Subject matter wherein either (a) the inertial member either comprises or is supported by an object suspended from a fixed support so that it is free to swing back and forth or (b) the device is responsive to a force resulting from collision of one body with another.
