A portable leveling vacuum tool to align a substantially flat top surface of a plurality of workpieces in a coplanar orientation. The vacuum tool includes a pair of parallel frame rails spaced apart from each other to define an intermediate area therebetween. The frame rails have substantially flat, coplanar bottom surfaces that define a planar reference surface against which the top surfaces of the workpieces are positioned. One or more vacuum cup assemblies are movably mounted to the frame rails using a support plate adjustably movable along the length...


[ We claim:] [1.] A portable leveling vacuum tool for use with a plurality of workpieces having at least a predetermined width to align substantially flat top surfaces of the workpieces in a coplanar orientation, comprising:a pair of elongated frame rails positionable in spaced-apart parallel relation to each other, each of said frame rails having an elongated bottom surface, said bottom surfaces of said frame rails being spaced apart in a coplanar relation by less than the predetermined workpiece width for engagement of each of said bottom surfaces with...
