Definitions

  • ABSTRACT A replaceable cutting edge for a material handling implement including a floor forming a leading edge with a plurality of adjacent openings, the cutting edge having an elongated slot for receiving the leading edge of the floor and a plurality of downwardly and rearwardly extending tangs for penetrating the respective openings, a tapered element urged into engagement between the floor and cutting edge to urge the leading edge of the floor into the slot and to simultaneously urge the tangs rearwardly into locking engagement with the respective holes.
  • FIG. I A portion of a loader bucket is illustrated at 11in FIG. I as an exemplary implement with which the replaceable cutting edge of the present invention may be employed.
  • the loader bucket includes a floor 12 formed from plate metal and having a leading edge 13.
  • the loader bucket also has side walls as indicatedat l4 and 16.
  • An elongated member 17 having a cutting edge 18 is constructed according to the present invention for replaceable mounting upon the leading edge 13 of the bucket floor 12.
  • the cutting member 17 In order to firmly secure the cutting member 17 in place upon the leading edge 13 of the bucket floor. the cutting member is formed with an elongated shoulder 19 providing a slot 21 facing rearwardly or away from the cutting edge 18 to receive the leading edge 13 of the floor 12.
  • the bucket floor 12 is also formed with a plurality of openings 22 adjacent and rearwardly of the leading edge 13.
  • the cutting edge is formed with a like number of downwardly and rearwardly extending tangs 23 suitably spaced to be received by the respective openings 22.
  • the tangs 23 and the slot 21 cooperate in a manner discussed immediately below to firmly secure the cutting member 17 in place upon the implement floor 12.
  • the cutting 'member 17 is urged into engagement with the bucket floor 12 by means of a plurality of tapered bolts 24.
  • a forwardly facing portion of each tang 23 is tapered as indicated at 26.
  • an opposed surface 27 formed by each of the openings 22 has a similar taper.
  • the bolts 24 penetrate the cutting member 17 for threaded engagement with nuts indicated at 28.
  • the cutting member 17 is urged rearwardly or in a leftward direction as viewed in FIG. 3.
  • the slot 21 is urged into engagement with the leading edge 13 of the bucket floor 12.
  • the tangs 23 are locked within the openings 22 in a position which may be best seen in FIG. 3.
  • FIGS. 4 and 5 illustrate a variation of the replaceable cutting member construction of FIGS. 1 3.
  • the cutting member 17' of FIGS. 4 and 5 is similarly mounted adjacent the leading edge 13' of a bucket floor 12' but is further. adapted for the mounting of spaced apart digging teeth 31.
  • the cutting member 17 has a somewhat differently figured cutting edge as indicated at 18.
  • a plurality of adapters 32 are secured to the cutting member 17, for example, by welding, in spaced apart relation to provide mountings adapted to receive the respective digging teeth 31.
  • the digging teeth 31 are secured in place upon the respective adapters by means of retaining pins 33 arranged in vertical bores 34 passing through each tooth 31, the respective adapter 32 and the cutting member 17 adjacent its cutting edge 18.
  • a replaceable cutting member for a material handling implement including plate means forming a forwardly facing leading edge for the implement, a plurality of openings being formed in the plate means rearwardly of the leading edge, the cutting member forming an elongated cutting edge and a slot facing away from the cutting edge to receive the leading edge of the plate means, the cutting member having downwardly and rearwardlyextending tangs for penetrating the respective openings in the plates means, tapered means engaging the plate means and cutting member to urge the leading edge of the plate means into the slot and to simultaneously urge the tangs rearwardly into locking engagement with the holes of the plate means.
  • the replaceable cutting member of claim 1 comprising a plurality of digging teeth arranged along the cutting edge thereof in spaced apart relation and secured to the cutting member by suitable adapter means and retaining means.
