Abstract: A workpiece to be cleaned or otherwise operated upon, for example a musical cymbal, is supported by a holder having the form of a belt. The belt's lower edge rests on a work surface. Its upper edge supports the workpiece rim, holding the workpiece off the work surface. In use, the belt is constrained to lie in a closed curve by means which removably fasten its outer end to an intermediate place along its length. The belt's perimeter length is adjustable to accomodate workpieces of widely varying sizes. To prevent unwanted movement of the workpiece with respect to the belt, or of the belt with respect to the work surface, the belt is given friction means, which can be bands or strips of rubber, either running lengthwise along the belt or wrapped around it.

Abstract: A hand-held, manually operated book index notch cutter is placed in the book to be notched. The notch cutter has a cylindrical cutting member (405) which moves parallel to and rotates around its axis. The axis of the cylinder is perpendicular to the book leaves being notched. The cutting member rotates and advances within a cutter guide (200), which is attached to a thin baseplate (100). The upper surface of the baseplate is a resilient platen (102) on which rests the stack of book leaves to be cut. These leaves are adjusted in fan and lateral angle with the help of a leaf guide (300), which is movable to allow a range of notch depths. The cutting member is attached to a knob (401) which is pressed and turned. Inside this cutting member-knob assembly is a spring-loaded ejector assembly (500). After a notch is cut, the ejector button (501) is pressed, capturing the paper cuttings and raising the cutting member to the ready position.
