Abstract
A device for swaging a ferrule onto the periphery of a cylindrical member includes a piston mounted for reciprocation within a body and an anvil member drivingly connected to the piston and having a recess in one end to receive the end of the cylindrical member. A camming body is associated with the anvil member for camming a ferrule carried on the end of the cylindrical member into tight peripheral engagement therewith. A gauge device is associated with the camming body for measuring the movement of the camming body relative to the body housing the piston. The camming device includes an articulated signal member having a first arm and a second arm one end of which is secured to the end of the first arm. The second arm is selectively pivotable about the first arm and a resilient spring is used to urge the second arm to one end position in relation to the first arm. A biasing member is used for moving the signal member from a first to a second position. The signal member is held in the first position until a predetermined amount of relative movement has taken place between the camming body and the piston housing body. At that time, the signal member is caused to move suddenly to the second position under the action of the biasing member.
