The Tool Grasps the Edge of the GlassPlate and Bites It Off With a Tooth or Point WILLIAM SPANGLER, a residentof Illinois, has invented an im-proved glass-chipping tool which has forits purpose the ornamentation of plateglass by scalloping. Theordinary glass-chipping toolcan be used on glass of onethickness only, and when aplate of another thickness isto be chipped another toolmust be employed. Thetool grasps the edge of theplate between a bearingpoint and a bit and bites itoff with a tooth, or point,provided for the order that the same toolmay operate successfullywith varying thicknesses ofglass it is necessary that thespace between the bearingI)oint and tlie bit be adjust-able in two directions—transversely of the edge ofthe glass and longitudinallyof the handle of the tool, sothat the bearing point shallim])inge the glass at varying<listaiices from the edge. The invention referred toprovides for tills double ad-justment of the jaws. How Hea
