Abstract
This invention relates to an internal locking puller device which comprises three pivotally mounted jaws, a cam ring which engageably slides along the jaws for camming together and apart the jaws for locking about bushings, bearings, seals, and the like, a disk-like collar to which the jaws are pivotally mounted, a T handle for adjustably controlling the movement of the cam ring, a slide rod, and a slide hammer slidably and reciprocally mounted on said slide rod for providing impacting force to remove the bushings, bearings, seals, and the like. The jaws have arcuate rearward portions with a pair of arcuate rails integrally extending from and along under edges thereof. The rails conform to the configuration of the arcurate rearward portions of the jaws so as to provide uniform locking strength across the jaws to virtually eliminate slippage of the jaws from internally about bushings, bearings, seals, and the like. The rearward portions of the jaws are precisely designed to greatly improve the leverage needed to substantially lock the jaws about the bushings, bearings, seals, and the like to prevent slippage of the jaws during the use of this device.
