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 has bosses or raised portions which separate the housing into three vertical channels the sides of which are intact down to the open bottom ends thereof. The bosses are for mounting a chain support bar and a guard member and the channels are first, for the ascending chain, the second is for the descending chain, and the third, for venting sawdust. A deflector deflects sawdust into the vent channel. A sprocket floats on a splined shaft to accommodate different support bars, and special oiling ducts and special support bar adjustments are disclosed.
