  • One of the objects of this invention is to provide a finishing and polishing machine which obviates the foregoing requirements.
  • Another object of this invention is to provide such a device which eliminates the necessity of having a container for storing the finishing and/ or polishing material, as well as maintaining a separator, as has been required with previous machines of this type for separating finished parts from said material.
  • An additional object of this invention is to provide such a device which allows discharge. of undesirable grit or waste as the finished parts are discharged and separated from the finishing and polishing material.
  • a further object of the invention is to provide such a device which eliminates the need for an extraneous separating device, hoist pan or other receptacle, and overhead traveling crane, and thus allows considerable saving in capital equipment outlay, labor and time.
  • a still further object of the invention is to provide such a device which may be readily adapted to an automatic cycle by interconnecting the various components of the device with time-controlled actuating units, for example, in such a manner as to provide timed charging of pieces to be finished or polished, finishing and/or polishing material and appropriate cleaning or other chemical compounds, timed discharge of finished and/or polished parts and waste separation, and return of utilizable finishing or polishing material to the hopper for reuse with additional parts, et cetera, andfinally, timed dumping of all of the contents of the hopper or tub in case such is desired as a part of the work cycle.
  • Still an additional object of the invention is to provide a finishing and polishing machine which readily lends itself to operation involving recirculation of parts to be finished or polished with a plurality of different cleaning or other chemical solutions.
