Abstract
Abstract A CASING WITH AN OPEN-ENDED TAPERED BORE IS SLIDABLE ON AN ELONGATED TAPERED HANDLE TO A LOCKED OR WEDGED POSITION. A SUPPLY OF FLOSS IN THE CASING EXTENDS THROUGH THE BORE IN ONE DIRECTION, THEN ACROSS AN OPEN RECESS IN THE TAPERED END PORTION OF THE HANDLE, AND THEN IN THE OTHER DIRECTION THROUGH THE BORE, SO THAT PORTIONS OF FLOSS IN THE BORE MAY BE WEDGINGLY LOCKED AGAINST THE HANDLE TO RETAIN THE FLOSS TIGHTLY STRETCHED ACROSS THE RECESS, WHEN THE CASING IS SLID TO ITS LOCKED POSITION. THE CASING CONTAINS A ROTATABLE SPOOL ON WHICH THE FLOSS SUPPLY IS CARRIED.
