From the 1863 edition of John Timbs' Year Book of Facts in Science and Art: "This invention, by William Jackson of Leeds, consists of 'Improvements in Mortising Machine,' connecting the hand lever of a mortising machine to the apparatus which carries the cutting tool by means of a link, so as to produce the required vertical motion of the cutter or chisel. The spindle to which the cutting tool is fixed passes through an upright casting, or box, or cylinder fixed upon the spindle. These two parts move together vertically; but the spindle has an independent axial motion, so that the position of the cutter may be altered when required. The cutting operations is effected by bringing down the chisel by means of the hand lever; and the wood under operation may be moved forward as required by means of the toothed gearing connected with the moveable bed on which the wood is secured." |
