Description: |
| The nature of my invention consists in providing the apron or aprons of any lathe with a slot for the purpose of moving the carriage of any lathe either way, as may be required, the length of "the slot-, without opening the shear-knot. Great difficulty has been experienced in replacing a chisel on the lathe when cutting screws, if from course of accident or necessity the chisel has to be taken out before the whole length of the screw is cut. It is almost impossible to bring the point of the, newly inserted chisel in the same place where the chisel taken out had left off. In all lathes now in use, the shear-knot has to be opened in order to more the carriage to the desired point, but when the proper place is found, the shear-knot may not exactly fit in the grooves of the screw which moves the carriage. |
