Definitions

  • portable power planers comprise a motor driven rotary cutter head having one or more cutting blade assemblies disposed thereon for performing a planing operation on the surface of a workpiece as the cutter head rotates.
  • the bottom surface of the tool consists of a fixed shoe located rearwardly of the cutter head and an adjustable shoe disposed forwardly of the cutter head. As the front shoe is adjusted upwardly or downwardly, the cutting depth of the cutting blade of the planer is adjusted accordingly.
  • the adjustable front shoe of a portable power planer typically includes an integral stem or sleeve that is threaded either directly to an adjustment cap disposed atop the front end of the housing or to a threaded shaft or bolt that is in turn fastened at its other end to the adjustment cap for rotation therewith.
  • a powerful compression spring is interposed about the sleeve between the shoe and the housing to maintain the elevation of the adjustable shoe in the position set by the operator.
  • the compression spring is held in compression between the adjustable shoe and the housing and must be of sufficient strength to resist the natural tendency of the operator to bear down upon the planer when performing a planing operation, and yet be sufficiently compressible to permit convenient upward adjustment of the adjustable front shoe.
  • the operator can overcome the thrust force of the compression spring and dislodge the adjustable shoe from its preset position, thereby causing an undesired variation in the depth of cut.
  • the elevation adjustment arrangement includes an adjustable shoe having fixedly attached thereto a rod extending upwardly therefrom which is threadedly engaged at its upper end to an elevation positioning nut rotatably mounted in the housing and fixed against elevational movement relative thereto.
  • An adjustment cap disposed atop the housing is affixed to the positioning nut so that rotation of the adjustment cap results in elevational movement of the adjustable front shoe.
  • a tension spring is connected between the front end of the adjustable shoe and the housing to cancel out tolerance play between the adjustable shoe and the housing. Because the tension spring works with the operator as he bears down upon the tool, no unwanted movement or wobble of the adjustable front shoe results.
  • the preferred embodiment of the present invention includes means for calibrating the elevation adjustment mechanism so that when the scale provided on the adjustment cap reads zero, the adjustable shoe is set for zero cutting depth.
  • a positive park position is also provided which when engaged sets the adjustable shoe below zero elevation so that the cutting blades will not mar the surface upon which the tool is placed.
  • the adjustable front shoe 30 includes an integral socket-like projection 32 extending upwardly from the base thereof.
  • Projection 32 also contains diametrically opposed, radially outwardly extending integral flanges 34 which are adapted to be received within a pair of slots 36 ( Figure 3) formed by boss members 38 in housing 22.
  • the left-hand housing member shown in Figure 3 is illustrative of the complementary-shaped right-hand housing member.
  • the flanges 34 serve to laterally stabilize the adjustable front shoe 30 as well as prevent the front shoe 30 from rotating relative to the housing 22.
  • An S-shaped rod 40 is fixedly mounted at one end in the socket-like projection 32 of adjustable front shoe 30.
  • An elevation positioning nut 42 is threadedly engaged to the upper end of rod 40.
  • Elevation positioning nut 42 is rotatably mounted within a race 44 formed in housing 22 by the joinder of the right-hand and left-hand halves.
  • the race 44 permits rotation of elevation positioning nut 42 relative to the housing 22 but prevents elevational movement with respect thereto.
  • a scale 64 is provided on the top surface of control knob 46 which is referenced to an arrow 62 ( Figure 12) located on the outer surface of housing 22.
  • the scale 64 on control knob 46 is calibrated in the following manner. Initially, with the control knob 46 removed, the elevation adjustment nut 42 is rotated until the adjustable front shoe 30 is located in the zero depth of cut position. The control knob 46 is then properly oriented and fastened onto elevation adjustment nut 42 in the manner described so that the reference arrow 62 on housing 22 is aligned with the zero indication on the scale. Thereafter, manual rotation of control knob 46 will cause rotation of elevation adjustment nut 42 and a corresponding variation in the elevational position of front shoe 30, which will be reflected in the reading on the control knob scale 64.
  • the present tension spring 70 works with the operator as he bears down upon the tool during operation.
  • the adjustable front shoe 30 appear to "float" as in the case of a compression spring when the force of the spring is balanced by the downward force exerted by the operator.
  • the present tension spring 70 works with the natural tendencies .of the operator, the adjustable front shoe 30 is always maintained in the desired elevational position.
