Ceiling tile cutting apparatus

A ceiling tile cutting apparatus for the cutting and edging of successive tiles with corresponding angular cuts in a corresponding manner, said apparatus comprising:

• a plurality of vertically arranged support legs connected by a plurality of horizontal members;
• a planar table member of generally rectilinear configuration attached at the upper end of said support legs, said table member having a first or proximal edge, a second or distal edge parallel to said first edge, a left hand edge and a right hand edge generally parallel to said left edge;
• an elongated slot extending through said table member parallel to said right hand edge of said table member;
• a pair of guide rails supported over said elongated slot;
• a motorized cutting tool mechanism arranged to slide on a carriage base mounted on said guide rails, with a cutting tool extending into said slot;
• an adjustable ruler pivotably arranged on said table, said ruler having an arrangement of elongated slots therein, one of said slots at a first pivot axis location with a pivot pin therein, and a second pivot axis location in said table to permit said adjustable ruler to be adjustable both longitudinally with respect to said pivot pin and to guide tiles on said table from a plurality of base locations and allow tiles to be cut more efficiently, wherein said adjustable ruler comprises a further rule and has a first and a second end, said second end arranged to extend over the right hand side of said table to permit repetitive identical cuts in small pieces of tile without re-measurement of each successive cut;
• said adjustable ruler having two separate graduated scales thereon, each of said scales increasing from a common point on said rule outwardly, to permit measurement to the left and right from said common point, said common point comprising a cutout on an edge of said adjustable ruler, said common point also being in alignment with a cutter on said cutting tool mechanism when said cutting tool mechanism slides on said rail guide.
