  • Pressure-responsive apparatus for assembling track links or the like
    Patent number: 4339961
    Abstract: Conventional apparatus for assembling a track chain tend to impose undesireable bending moments and residual loads thereon. The apparatus (22) of this invention overcomes these problems by providing a pair of movable pressure heads (26,28) registering with first and second contact points (142,144) on opposite ends of a chain link (134) and a pressure equalizing plate (68) for sensing the resistance force at each contact point (142,144) to direct an increased pressure to a selected one of the contact points (142,144) in response to the differential between the resistance forces at the contact points (142,144).
