LOCKING COVER ASSEMBLY FOR USE WITH A CHAIN SAW ABSTRACT OF THE DISCLOSURE A locking cover assembly is disclosed which is particularly usable with a conventional chain saw wherein the assembly includes a cover extending about and surrounding the chain and bar cutting assembly of the chain saw while defining a slot extending longitudinally along the bottom edge thereof to facilitate cutting. The cover is hingedly secured with respect to the housing of the chain saw to allow the cover to swing vertically upwardly responsive to cutting movement by the cutting assembly. Wing members are included extending longitudinally along the slot to facilitate movement of the cover during cutting. A biasing spring is included for holding the cover in the down enclosed position when the cutting assembly is not in use. A locking apparatus is included which has a plurality of guide rods fixedly secured with respect to the housing and defining apertures through which a movable locking pin extends. This locking pin is pivotally secured with respect to a wheel means which is movable between a closed position and an open position to facilitate locking of the cover means in a down position. A spring means is included for holding the locking pin and wheel in the closed position unless the locking apparatus has been moved by pulling against the lock trigger by the user. A rear runner and a front runner are positioned upon the top of the hinge to facilitate the downward bias exerted by the wheel means to hold the cover in the locked or unlocked positions.
