ABSTRACT:
A pilfer-proof system for locking spools holding chains of valuable material displayed in a case which includes the spool having a cylindrical portion having an axial hole and opposed radially extending rims connected to the cylindrical portion with the chain spooled around the cylindrical portion, a pivot extending through the axial hole and mounted to side walls of the case, and a locking member adapted to hold the spools in a frictional locked mode upon the action of the salesman until released from the locked mode by the salesman. The locking member can be a cylindrical locking member rotatably mounted to a semicylindrical bracket at one of the walls and having an axial pocket having internal threads adapted to mate with external threads at the end of the pivot. When the locking member is screwed onto the pivot, a pressure ring at the end of the locking member presses against the near rim of the near spool which in turn presses the following spools against another pressure ring near the other wall. The locking member can be a bar over the spools provided with frictional mechanism adapted to prevent unspooling of the chain. The locking member can also be a screw threaded through one wall capable of being screwed against the rim of a spool so as to create a friction lock against a pressure ring at the other wall.
