Description: |
| From the "Journal of the Franklin Institute": "The subjoined claims, although they do not lead to a knowledge of the particular structure of the parts, serve to show that the improvements are in mere matters of arrangement, leaving the rest of the structure the same with that of other mortising machines. 'I claim the construction of the carriages with the rests, bar clamps, and clamp bolts, as described. The arrangement of the lever and wedge for throwing the pinion out of gear, with the racks, as described. The method of connecting the pulley with the piston shaft by the spring, for allowing the pulley to turn on the shaft as the cutting tool enters the wood.'" |
