ABSTRACT:
The present invention comprises a ceiling tile cutting apparatus for the cutting and edging of successive tiles with corresponding angular cuts in a corresponding manner. The apparatus comprises a plurality of vertically arranged support legs connected by a plurality of horizontal members and a planar table member of generally rectilinear configuration attached at the upper end of the support legs. The table member has a first or proximal edge, a second or distal edge parallel to the first edge, a left hand edge and a right hand edge generally parallel to the left edge. An elongated slot extends through the table member parallel to the right hand edge of the table. A pair of guide rails supported over the elongated slot, and a motorized cutting tool mechanism is arranged to slide on the guide rails, with a cutting tool extending into the slot. An adjustable telescopable ruler is pivotably arranged on the table. The ruler has a first pivot axis location and a second pivot axis location to permit the adjustable ruler to guide tiles on the table from a plurality of base locations and allow tiles to be cut more efficiently.
