Abstract
There is disclosed a conversion chain saw in which a circular power hand saw which has been converted into a saddle-type chain saw is modified so that it is adapted to use a pin-and-groove-type chain saw and to be again converted back to a saddle-type chain saw. There is mounted on the drive shaft, a dual sprocket composed of a saddle-type chain-saw sprocket, which may be the one in the original conversion, and a pin-and-groove-type chain-saw sprocket. The two sockets are mounted on the shaft in juxtaposition. A shim-plate provides a secondary mounting base for the support bar for the pin-and-groove type. It has an oil tube and conduit for conducting oil into a complementary oil conduit in the new support bar. A suitable coupling nipple is provided to provide for continuity in the oil circuit which takes advantage of the oil circuit already provided in the original conversion.
