Definitions

  • My invention relates to bits for woodworking'tools and machines but. particularly to plane bits.
  • An object of .my invention is to provide a bit having improved means for holding the cutter.
  • Another object of the invention is the provision of means to prevent transverse movement of the cutter in the bit.
  • Another object of the invention is the inclusion of means to guide the clamp plate into position.
  • a further object of the invention is the provision of frictional resistance element to prevent accidental movement between the cutter .blade and the clamp plate when they are in released position.
  • Figure 1 is a central vertical section through one of my bits assembled in a smooth plane.
  • Figure 2 is a perspectlve view of my bit,-v a portion of the clamp plate and spring plate being broken away to show the construction.
  • Figure 3 is a side elevation of my bit .111 clamped position.
  • Figure 4 is a side elevation of my bit 1n released position.
  • Figure 5 is a perspective View of a. 11106.11 tied form of bit, a portion of the clamp plate being broken away to disclose the con struction. 1
  • Figure 6 is a side elevation of the rabhated and grooved end of the cutter blade.
  • the .bit of my invention comprises" a cutter. blade formed with the usual elem;
  • the end of the cutter blade is provided with a rabbet- 4 and a shallow groove 6 adapted to receive the non-cutting edge 7 of the cutter 8. Overhanging the groove dis a shoulder 9 against which the non-cutting edge 7 of the cutter bears. Asshown in Figures 4 and 6, the groove is disposed in misalinement with, or at a slight angle to, the bottom of-the rabbet so that the cutter seated in the groove extends outwardly and upwardly slightly above the'surfacc of the 'rabbet. Disposed in the groove, preferably adjacent the center thereof, is a pin 11 which engages a complementary notch in l the non-cutting edge of the cutter. By this means any longitudinal movement of the cutter is prevented,
  • a clamp plate 17 Overlying thev cutter blade and secured thereto by the usual set screw 16 is a clamp plate 17, the lower end of which is arched in the usual way and terminates in the clamping edge 18.
  • the lower half of the clamp plate is bent slightly upwardly and away from the cutter blade so that when the clamp plate and the cutter blade arev rigidly secure-d together by the set screw 16 in superposed relation, the clamping edge 18. lies somewhat above the end 19 of the cutter blade.
  • the cutter 8 lies at an angle to and is spaced above the rabbet, but in such a position that it is free of contact, or contacts lightly, with the clamping edge 18 of the clamp plate.
  • Means are provided for resiliently retaining the cutter in position in the cutter blade when not securedbyxthe clamp. plate, so that the bitmay: be removed from thei plane and handled withontthe cutter fallingfrom its seat.
  • Disposed on each side of the spring plate 20, and preferably integral therewith, are flanges 22, extending upwardly to form guides for the clamp plate, so that the clamp plate may be slipped into position on the cutter blade without difficulty in securing alinement of the two plates.
  • the bit of my invention is positioned in the plane in the usual manner with the hold 3 and 27 of the cutter blade and the clamp plate respectively, and the adjusting stud engaging in the slot 28.
  • the wedge is then dropped over the holdingstud and the lever 29 pushed down so that the bit is locked in position.
  • a bit comprising a cutter blade having a rabbeted end and a groove formed in the end wallofthe rabbet, a cutter seated in said groove, said groove being'misalined with the'rabbet to position the outer edge oi the cutter above the rabbet, and means actuated by the clamp of the plane for flexing the cutter into a seat in the rabbet.
  • A-bit comprising a cutterblade having;
  • a rabbeted end and a groove formed in the end wall of the rabbet a cutter seated in said groove and having a notch in the noncutting edge, said groove being misalined with the rabbet to position the outer edge of the cutter above the rabbet, a pin in said groove adapted to seat in said notch to prevent transverse movement of the cutter, and a clamp plate for flexing the cutter under tension to a seat in said rabbet.
  • a bit comprising a cutter blade having arabbeted end and a groove formed in the end wall of the rabbet, a cutter seated in said groove, means interposed between said cutter and groove to prevent transverse move ment of the cutter, said groove being misalined with the rabbet to position the outer edge of the cutter above the rabbet, and a clamp plate for pressing the cutter to a seat in said rabbet.
  • ' 6. bit comprising a cutter blade having a rabbeted end and a groove formed in the end Wall of the rabbet, a cutter seated in said groove, resilient means for retaining the cutter in said groove, said groove being misalined with the rabbet to position the outer edge of the cutter above the rabbet, and a'clamp-plate for presing the cutter to a seat in said rabbet.
  • a bit comprising a cutter blade having a rabbeted end and a groove formed in the end wall of the rabbet, a cutter seated in said groove, said groove being misalined with the rabbet to position the outer edge of the cutter above the rabbet, a clamp plate forv pressing the cutter to a seat in said rabbet, and flanges on each side of the cutter blade-to guide the clamp plate into position.
  • a bit comprising a cutter blade having a rabbeted end and a groove formed in the end wall of the rabbet, a cutter seated in said groove, said groove being misalined with the rabbet to position the outer edge of the cutter above the rabbet, a clamp plate for pressing the cutter to a seat in said rabbet, a resilient plate secured to the cutter .
