Description: |
| From the 28 April 1860 issue of Scientific American: "The object of this invention and improvement in mortising machines is to throw into and out of place the mortising tool, and for reversing the movement of the same at any desirable moment, without shifting the belts or stopping the rotary motion of the auger to adjust the parts; at the same time to have the mortising tool advance or recede from the timber, instead of the timber to the tool. The invention consists in giving a rotary motion to the auger, and at the same time an alternate reciprocating movement to the chisel stock by means of a friction wheel and counter shaft which is hung at one end in a movable bearing arm operated by a suitable treadle so as to bring the periphery in contact with the main shaft, and to relieve it from said shalt at pleasure; and in conjunction therewith, is arranged a pinion bevel-gear wheel for rotating a cam shaft, for giving the advancing and receding motion to the mortising chisel, and for giving a simultaneous movement to the belt wheel on the main shaft. It also consists in arranging above the friction roller a counter roller, which receives its motion from the main shaft by a belt, or suitable gearing whereby the friction roller may be made to reverse its motion, and thus give an instantaneous receding movement to the auger and chisel. The patentee of this invention is Lovett Eames, of Kalamazoo, Mich." |
