Abstract:
A level-adjusting apparatus for adjusting the level of a tool implement for cutting a piece of work on a working surface on which the work to be cut is placed, said level adjusting apparatus comprising:a carriage mounted beneath said working surface and adapted to support said tool implement such that said cutting implement projects through and above said working surface, said carriage being separate and apart from said tool implement and having means for removable attachment thereof to said tool implement; means for altering the level of said carriage; and handle means comprising a rotatable stem which is removably mounted to and extending upwardly from said working surface and operatively connected to and activating said altering means, wherein said altering means include a spindle threadably mounted to said carriage, wherein the spindle and said tool implment are axially spaced from each other, said rotatable stem being mounted for rotation and being operatively connected to said spindle for causing said spindle to rotate with resulting alteration in the level of said carriage; wherein said spindle has threads which mate with threads formed in said carriage, and said apparatus further having means for tightening the threads of said spindle to the threads of said carriage to prevent slippage between the threads of said spindle and the threads of said carriage throughout the length of travel of said carriage.
