Patent ID: 7416400

Claim:
An apparatus for extrusion of pliable clay material in alternatively selectable design shapes, said apparatus comprising: a substantially cylindrical hollow sleeve having a body portion with a first end and a second end; an elongated screw having a first end within said sleeve and a second end at least partially outside of said sleeve; a reinforced plunger associated with said first end of said screw within said sleeve, said plunger comprising a first face facing away from said screw and a second face opposite said screw, said second face being substantially thicker than said first face; sealing means between said plunger first face and plunger second face and encircling the periphery of said plunger and sufficiently sized to be in simultaneous contact with said plunger and the interior of said sleeve; a screw cap associated with said second end of said sleeve and having a top with a central aperture through which said second end of said screw extends; a handle associated with the second end of said screw; extrusion shaping means associated with the terminus of the sleeve first end and being perforated to restrict but still allow the movement of said pliable material through said extrusion means in one of said selectable designs and said plunger includes swivel means such that rotation of said screw does not rotate said plunger against said pliable material and an aperture for insertion of said screw first end there through and said swivel means retains said plunger to said screw first end but does not restrict rotation of said plunger with respect to said screw first end; said screw first end defines an internally threaded bore and said swivel means is a screw having an external thread to engage said internally threaded bore.
