Definitions

  • the numeral 10 designates an elongated wooden rail having a generally rectangular transverse cross-section.
  • the rail 10 is shown at various stages of the bow cutting and milling process provided by the present invention. While such a rail has numerous uses,
  • the elongated rail 10 has a pair of oppositely disposed, longitudinally extending surfaces 12 and 14 which, in accordance with the present invention, are milled in the following manner.
  • FIG. 1(a) an unmilled rail 10 is shown in which the surfaces 12 and 14 are illustrated as being generally straight.
  • a concave bow is first cut into the surface 12 as shown in FIG. 1(b).
  • rail '10 is milled along surface 14 so as to define a U-shaped groove therein (not shown) for receiving a lite of glass. This is done with surface 12 of rail held flush against a moulder guide (not shown) so as to remove the concave bow from surface 12 during the milling of surface 14.
  • This signal is transmitted to a pair of pneumatic cylinders 53a and 53b which are attached to the members 37 adjacent upright members 34a and 34b, respectively.
  • the prime mover 54 of each of the pneumatic cylinders 53a and 53b is directed toward the rails 10 and,'upon the cylinder receiving a signal from curvature sensor 40, the cylinders are actuated causing the prime mover'to eject the bowed rail from hopper 20. It should be understood that while the utilization of bow sensing mechanism 40 is highly desirable, its utilization is not essential to the operation of the present invention.
  • the guide means 62 includes the fixed guide rail 38 and a moveable guide 80which is biased toward the cutter blade 60 so as to urge the passing rail against the rail 38 and blade 60.
  • the guide 38 includes an opening 81 in which the blade 60 is p'ositioned for the aforementioned lateral movement toward and away from the passing rails 10.
  • Moveable guide member 80 includes two overlapping rail portions 84a and 84b pivotably attached to platform 30 and a pneumatic cylinder 85 having a prime mover 86 engaging guide rail 84a.
  • the pneumatic cylinder 85 applies a constant pressure (controllably pre-selected for the type of wooden rail being processed) to the overlapping guides 84a and 84b urging the passing rail against fixed rail 38 and blade 60.
