Abstract
Print hammer actuating apparatus of the double lever type in which one lever is moved in response to an input force and carries a pivotally mounted second lever which provides the output force through either an 'inertia' principle or 'ratio' principle. The angular velocity of the first lever is multiplied through those principles to provide greater impact velocity at the output of the second lever without requiring an increase of the input energy.
