Patent

CA 2077756

A circular tool assembly (20) adapted to be fitted together and secured on a power-driven tool arbor (22) includes first and second circular discs (24, 30), the discs defining a medial arbor-receiving opening and peripheral portions. At least one of the discs (24) defines an outer concave surface (36) extending continuously between the medial opening and the peripheral portion (28), and the disc further defines an inner, concave surface (38) extending continuously between the medial opening and the peri- pheral portion (28). The discs are adapted to be positioned on the arbor of the tool with a circular tool element (40), such as a chain saw circlet, positioned between and engaged by the peripheral portions of the discs to hold the element in position between the discs when the discs are forced toward each other along the arbor to tightly hold the tool element between the peripheral por- tions of the discs.
