  • This invention relates to shoe sole tting machines and is herein shown and described as embodied in a machine arranged to receive and perform a series of operations upon a sole blank,
  • the operations performed by the illustrated machine include rounding, forepart reducshank reducing, roughing and iinal trimming
  • the invention is not limited in its application to a machine which will perform all of those 'l operations, but includes within its scope improved mechanisms for performing only a part or parts thereof.
  • One object of the present invention is to widen the range of utility of such machines as that above referred to, providing a machine which is capable 3o of operating upon block soles as Well as died out blanks, and is capable oi operating all the Way around the sole.
  • a slidable and rotatable sole pattern supporting jack is provided with a cooperating clamping member arranged to hold a sole blank upon the pattern While the jack is rotated through a complete revolution, Without obstructing part of the periphery of the sole from the action oi the cutter or cutters arranged to operate upon it.
  • this result is secured by supporting the clamping member separately from the jack and keeping it in register with the pattern by connections, such as gearing or the like, between the clamping .member and the jack.
  • Another feature of the invention consists in the provision ci control mechanism operating to cause the cutter to be swung into engagement with the sole before the jack starts to turn and then caus- U ing the jackto turn so that the entire periphery of the soie will be operated upon. After the rotation cf the jack is complete, the cutter is retracted to an inoperative position where it will not interfere with the removal of the finished 55 blank.
  • a further feature of the invention resides in the provision of a tilting cutter head carrying a pair of cutters and having means for so biasing the head that the cutters engage the blank in succession when the cutter head is moved toward the blank to be operated upon.
  • the invention also includes a new construction and arrangement whereby the cutter, which is rotary and turns in a direction to cut toward the rear end of the sole, is caused to engage and cut into the edge of the sole at one side of the heel portion thereof, after which the jack is rotated in the direction opposite to the cutting action, causing the entire periphery of the heel portion ci the sole to be traversed past the cutter.
  • This initial engagement of the cutter with the sole as described permits the cutter to cut its Way into the sole with a minimum tendency to buckle the sole because the drag of the cutter is not directly toward the clamping member.
