The saw-disk, in case a circu-lar saw is to be gummed, is attached to the end K of the saw-bar, and the latter is properlyadjusted and fastened to the stock, in such position as to bring the saw-teeth properly underthe emery-wheel.

The wheel is previously adjusted to the proper angle of the tooth by partially rotatingthe the block F, and securing it when the wheel is at suitable inclination. When theapparatus is to be used to gum a straiglit-eiigid saw, the blade is conlined in a carriage, andthe w
