Description: |
| "The nature of my invention consists in making a bolt-cutter for cutting the threads of bolts, which shall have at least three cutters or dies, adjustable by means of cams, so as to cut different-sized bolts, the threads of which are cut by passing only once through the opening between the dies, and the dies are then immediately drawn back by means of cams and the bolt released without the delay of running it back by the thread; and also in making the bolt-cutter stationary, while the bolt revolves and is cut from the head to the point, and in preparing the dies by tapping them with a tap smaller than the bolt to be cut, so that as the circle made by the dies, when thus tapped, is enlarged by drawing the dies back to admit a bolt larger than the tap, the thread of the bolt is then cut only by a small portion of the face of the dies, friction is lessened, and greater ease, execution, and perfection of the thread is attained."
