Saw-tooth In′di-cator.
A device for insuring the filing or setting the teeth of circular saws to an equal distance from the center. It consists of a hollow shaft a, having a Vshaped point and two curved arms b c, which are adjusted to a groove in the saw-collar. The movable branch d, whose outer end has a knifeedge, is set to the proper distance from the center, and held in this position by a screw. The points of the teeth, if projecting beyond this distance, are filed down, or if they are too low and movable, they may be adjusted to proper hight by filing away the shoulder.Saw-toothing machine. |
