Stone slotting machine

A stone slotting machine comprising:

• a movable main frame;
• an arbor cutting blade having;
• an arbor frame;
• several bearings mounted at spaced intervals to said arbor frame, said several bearings being sealed at their ends to prevent contamination by water or stone particles;
• a number of cutting cylinders attached and aligned together and disposed between said several bearings, each of said number of cutting cylinders having a cylindrical body with opposite female threaded ends;
• several connecting shafts, one each extending through a corresponding one of said several sealed bearings, each of said connecting shafts having opposite male threaded ends adapted to threadedly engage said female threaded ends of adjacent ones of said number of cutting cylinders;
• means for rotating said attached and aligned number of cutting cylinders relative to said arbor frame;
• and
• means for reciprocatably and rotatably mounting said arbor cutting blade to said main frame including;
• means for providing a flow of oil between each of said sealed bearings and its corresponding connecting shaft.

A stone slotting machine comprising:

• a main frame defining a horizontal plane and including means for moving said main frame along the ground;
• a reciprocating arbor cutting blade adapted for cutting a slot in stone;
• means between said main frame and said arbor cutting blade for movably supporting said reciprocating arbor cutting blade on said main frame including;
• means for tilting said arbor cutting blade relative to said main frame about a first axis;
• and
• means for pivoting said arbor cutting blade relative to said main frame about a second axis,
• wherein said first axis is parallel with said horizontal plane, and said second axis is perpendicular to and rotatable about said first axis.

• said reciprocating arbor cutting blade including a first double action hydraulic piston for reciprocating said blade;
• said means for rotating including a second hydraulic piston;
• a reservoir containing hydraulic fluid mounted on said main frame;
• and
• a hydraulic pump for pumping said fluid from said reservoir to each of said first double action piston and second hydraulic piston.
