  • the members to be driven are cutter chains which are preferably mounted on jibs of different lengths, whereby the apparatus can produce stepped trenches.
  • the invention provides drive means comprising a pair of endless drive elements each having a run disposed to extend parallel and adjacent to an adjacently disposed pair of members to be driven, the arrangement being su'ch'that the driving elements are each disposed to engage a different one of the members to be driven, the driving elements and the members to be driven carrying spaced series of invnicgaging portions whereby movement of the driving digging machines, in which case the means obstructing v removal of the jib is the cutter chain carried thereby, enables the jib to be raised and lowered in a simple and convenient manner and removed and replaced as trench digging apparatus comprising drive means as defined above.
  • the invention provides apparatus for digging broad trenches comprising a pair of endless drive elements each having a run disposed to extend parallel and adjacent to an adjacently disposed pair of endless cutter chains, the arrangement being such that the driving elements are each disposed to engage a different one of the cutter chains, the driving elements and the cutter chains carrying spaced series of interengaging portions whereby movement of the driving elements causes corresponding movement of the cutter chains, and at least one further cutter chain being disposed between the said pair of cutter chains and arranged to be driven therewith.
  • the further cutter chain or chains may be mounted on sprockets driven by the sprockets on which the pair of cutter chains are arranged.
  • the cutter chains may be mounted on separate jibs of the trenching apparatus whereby the apparatus can cut'stepped trenches.
  • the invention may have application in fields other than trench digging, for example mineral mining and thus references to trench digging.
  • FIG. 6 is a side elevation of part of the embodiment of FIG. I
  • FIG. 7 is a side elevation of the lower part of ajib of a trench digging apparatus
  • FIG. 8 is an end elevation, partly in section corresponding to FIG. 7;
  • FIG. 9 is a side elevation of an apparatus for producing stepped trenches.
  • FIG. shows a drive arrangement for a multi-purpose trench digging apparatus.

  • Each link 3 of the cutter chain 1 is formed with a 'sprocket'tooth.
  • FIGS. 5 and 6 The arrangement shown in FIGS. 5 and 6 is generally similar to that described above with the exception that the member to be driven is in this case a beam or jib 1 1 formed along opposite sides thereof (in the-manner of the rack of a rack and pinion device) with a series of apertures 12 in which the teeth 9 of the driving chains 2 can engage so as to drive the beam or jib l1 longitudinally.
  • a device may, for example, find application in connection with'the cutter jib of trench-digging apparatus.
  • cutter chain ofjib at one time.
  • the driving effort is applied at positions favorably disposed between the positions in which load is applied to the cutters 8 and the hinge pins of the cutter chains.
  • FIGS. 7 and 8 of the drawings there is shownajib 11 for a trench digging apparatus of the kind having trained therearound an endless chain 16 carrying cutter teeth 17, the jib being arranged to be raised and lowered by drive means of the kind described with reference to FIGS. 5 and 6 of the drawings;
  • the jib is formed with a rack 12 which forms the driven member of the drive means.
  • the rack 12 extends close to the bottom or nose of the jib
  • FIG. 8 while most of the links of the driving chains are provided with teeth 9 a series of links of both driving chains 2 is not formed with teeth 9.
  • the plain or untoothed links of the drive chains 2 provide a clearance through which the jib can be lifted from between the driving chains-of the drive means.
  • the cutter chain itself can be positioned so that those cutter boxes replacement of the jib.
  • the drive chains are shown to have seven links carrying teeth engaging the cutter chain, followed by four links without teeth, to permit easy removal of the cutter chain.
  • the ratio of toothed to plain links would be somewhat different to prevent unduly high driving forces from being transmitted by the teeth. With two opposing driving chains this problem could be greatly reduced if the plain links are disposed in opposite relation to the cutter chain.
  • the drivingmeans of FIG. 9 is generally similar to those described in detail above, but in the present case the arrangement is modified so that each cutter chain 1 has only one drive chain 2 associated therewith.
  • the cutter chains 1 are mounted on jigs (now shown) of different lengths so that the cutter chains extend downwardly to different extents whereby theapparatu's will produce a stepped trench 18 Guiding means (not shown) will be provided between the two cutter chains in the region where the cutter chains are engaged by the drive chains to prevent the cutter chains from being displaced laterally in operation by the driving forces.
  • one or more further cutter chains are positioned between the pair of cutter chains 1 shown in FIG. 9 so that the trenching apparatus will produce a relatively broad trench which may or "may not be stepped depending on whether the jibs are ofdifferent lengths.
  • the inner cutter chain or chains are driven by one and/or other of the said pair of cutter chains by drivingly connecting the sprockets by means of which the various cutter chains are mounted on their respective jibs.
  • the sprockets may be mounted on common shafts.
