ABSTRACT:
A crimping tool for nut locks which comprise a ring type lock member having spaced apart teeth extending outwardly from the circumference and which are positioned adjacent a nut that is to be locked or held in place thereby when a selected one of the teeth is crimped or bent over to bear against the flat surface of the adjacent nut. The present invention comprises a flat support bar for placing over and across the outer end of the nut and member on which it is threaded, a puller member extends through an aperture at one end of the bar having a lateral projection or hook formed at its inwardly extending end with a puller nut threaded on the outwardly extending end of the puller member on the opposite side of the bar. The lateral projection or hook is positioned behind one of the teeth of the nut lock ring and the puller nut is then rotated to draw the tooth of the nut lock ring forward to crimp or bend over the surface of the adjacent nut. A slidably adjustable clamping lug is provided at the other end of the bar to clamp against an available housing portion when the puller is in position to engage and pull on a selected one of the teeth of the nut lock ring, thereby clamping and holding the bar in position while the puller crimps and bends the engaged tooth over one of the flat surfaces of the nut.
