  • an elongated compression leaf spring 25 is inserted into an elongated cut-out 27 in the inner portion of the base of the vane as the vane is. inserted in the channel 11.
  • the spring forces the blade upwardly so that the tapered sides 28 of the blade (FIG. 4) are urged against the inwardly tapered side walls 29 of channel 11 in the runner head .1.
  • the locking ring 9 is then put in place and the blade is operational.
  • FIGS. 9-15 show, in this instance, a single faced blade 7 which when operational has its outermost end flush with the periphery of the head 1 instead of extending therebeyond as with the embodiment of FIG. 3.
  • a different type locking pin 33 is also shown.
  • the pin is cylindrical with the upper surface being divided into a flat portion 35 and a tapering portion 37 (also see FIGS. 13-15).
  • the blade has a complementary shaped cut-out 38 with a flat surface 35' and a tapered surface 37' (see FIG. 12).
  • the tapered surface 37' abuts the pin taper 37 when operational.
  • the blade 7 is mounted and locked in place in the same manner as described with reference to FIGS. 2-5.
  • the blade 7 has the elongated cut-out 27 which houses the spring 25 for forcing the blade inwardly against the tapered side walls 29 of the runner head as described above.
  • FIGS. 16-22 show still another embodiment of blade and locking pin assembly. Here a single direction blade 40 is shown.
  • the pin 42 is cylindrical in shape and has a groove or indent 44 which faces the periphery of the head 1 (see FIGS. 20-22).
  • a screw driver blade or other blade is inserted in the indent and by wedging the blade upwardly the pin 44 is removed from its seat 46.
  • the walls 48 of the channel are straight as are the sides Stl of the vane 40.
  • the cut-out 52 at the outer end of the blade has a curved back or inner wall 54 as shown in FIG. 16, the lower inwardly curving end of which abuts against the pin 46 when operational.

  • FIGS. 23-30 show another embodiment of the aforedescribed blade and locking pin assembly.
  • the blade 60 is a two-faced blade wherein either face can be used for clockwise or counterclockwise rotation.
  • the faces of the blade taper inwardly which gives a sloping surface for the abrasive being fed thereto and thus provides a better propelling path or action of the abrasive since the forward portion of the tapered surface will contact and advance the abrasive before the innermost end thereof which will eliminate bunching of the abrasive on the blade as the abrasive is propelled outwardly along the blade face.
  • the lock pin 62 for the vane, the locking pin recess 64 in the wheel 1, and the locking pin recess 66 in the undersurface of the blade 60 are different than those described above.

  • the pin 62 itself is a cylinder having a shape as shown in FIGS. 2830 of the drawing.
  • the ends of the pin are parallel to each other and taper at an angle to the vertical axis of the pin with the ends tapering outwardly toward the wheel periphery.
  • the vane 60 is locked in place vertically by the spring 25 arrangement described in connection with the above-described embodiments.
  • the remaining structure is also as described in connection with the other embodiments.
