ABSTRACT:
There is disclosed a power-driven chain saw converted from a stripped-down power-driven circular power hand saw which has a unitary housing adapted to be mounted on the power unit of the stripped-down power-driven hand saw. The housing is offset axially to provide a relatively wide area on one side having a window therein through which sawdust is deflected. Support-bar mount is an integral part of the housing as are a sawdust deflector, an oil reservoir, and a support-bar mounting boss. A sprocket is splined to a hub from which it is easily removable and which, in turn, is splined to the drive shaft with a more firm splining. A cover is provided for the housing which closely conforms to the chain and has an axially disposed dent or impression therein to accommodate the hub of the sprocket.
