Fig. 3722 represents a saw-gummer made by Messrs. Snyder Brothers of Williamsport, Pa. The machine consists of a heavy cast-iron stock supporting a die. A punch is also provided, worked by the eccentric hand-lever shown. The end of the punch is partially cut away so as to leave a long tongue or projection, which is not drawn out of the die even when the punch is fully raised. The object is to support the punch and keep it from springing while cutting. Saws should be filed, gummed, and swaged on the under or face side of the teeth; and care should be taken not to gum below the line or circle of the back of the teeth. The teeth should be worn back around the saw. |
