SPECIFICATION TITLE: ICE CHOPPER METHOD AND APPARATUS FOR PRODUCING ICE PARTICLES OF CONTROLLED SIZE INVENTOR: JAMES E. WILLIAMS ABSTRACT An ice chopping method and apparatus are provided for a kitchen appliance such as a food processor or similar appliance of the type having a base containing a motor and a motor driven rotary tool drive which extends into a working bowl. The method includes mounting a rotary ice chopping tool on the motor drive in the working bowl and establishing an annular channel around and leading to the rotary ice chopping tool, forming an escape gap of predetermined size around the perimeter of the annular channel and feeding ice chunks which are to be fragmented into the channel in said bowl which fragments when reduced to the proper size are discharged through the escape gap and deposited in the bowl. The gap may be adjusted for varying the size of the discharged ice frag- ments. The apparatus includes a removable disc-like head having a socket therein on the underside thereof and at least one and preferably two radially spaced blades protruding upward from the flat disc-like member with the rotating front edge chopping the ice which it contacts. This socket is adapted to receive a removable shank which is coupled on a first end to the rotary drive of the appliance and on the second end into the socket, the second end of the shank and the socket both having the same geometrical shape. The second end of the shank has a key thereon which fits into spaced key shaped channels in the socket which penetrate to different depths in the socket for providing a way of varying the size of the escape gap between the annular channel member and the rotary tool for varying the size of ice fragments which are produced by the appliance. The annular channel member has a cylindrical downwardly extending skirt, extending from an upstanding peripheral shelf which fits onto the bowl and is adapted to receive a cover which includes auxiliary locking cams which are adapted to actuate the motor in the ice chopping appliance.
