ABSTRACT:
Apparatus for manually cutting both circles and strips from glass utilizes either a center support structure or an edger, in combination with a rule having different scales on opposite surfaces, and with a cutting head adjustably mounted on the rule. Reversal of the position of the cutting head on the supporting rule adapts it for use with either of two different forms of cutting components, and the edger is constructed not only to compensate for offset between the registration and cutting elements of the head, but also to enable use of the edge of either the glass workpiece or a furring strip as the reference surface along which the edger is run to cut strips.
