Patent ID: 8302272

Claim:
Apparatus for swaging a collar onto an externally grooved member having grooves in the form of a thread or grooves which extend circumferentially around the member, which apparatus comprises: jaw means which are openable to receive the projecting end portion of such a grooved member on to which a collar has been placed, the jaw means being internally grooved and being closable so as to engage the grooved member; a trigger, swaging means radially outside the jaw means and axially movable with respect thereto, whereby when the jaw means is closed and engages the grooved member, and when the trigger is pressed thereby applying an appropriate axial force to the swaging means with respect to the jaw means, the swaging means is forced forwardly over the collar to swage the collar into engagement with the grooves of the grooved member; and automatic axial position adjustment means for automatically making minor axial adjustment of the position of the jaw means, after the grooved member has entered the jaw means and prior to pressing of the trigger, to correctly align the grooves of the jaw means with the grooves on the grooved member, thereby to enable closure of the jaw means to engage the grooved member.
