Inclined Chisel Patents (Class 144/88)
  • Patent number: 5305812
    Abstract: A bench mounted machine allows an operator to produce both mating components for woodworking through and half-blind dovetails in workpieces suitable for case construction and drawer construction with computer controlled programmable flexibility to determine size and centerline spacing of pins and tails as well as half-pin widths. Symmetrical and asymmetrical through and half-blind dovetail configurations can be created without the use of guide templates or fixed spindle arrangements. Stationary workpieces are mounted vertically and horizontally above an automated two axis dovetail cutting means. Pins and tails for interlocking through and half-blind dovetail joints are milled in the ends of workpiece boards based upon operator input commands from a personal computer control station.
