ABSTRACT:
A stone slotting machine includes a main frame movable on tracks disposed on the ground at a stone quarry. The slotting machine further includes cutting blade having an arbor frame, a number of cutting cylinders attached and aligned together and being rotatably mounted to the arbor frame and a drive motor for rotating the number of attached and aligned cutting cylinders relative to the arbor frame. The arbor cutting blade is reciprocatably supported on a carriage. The carriage itself is supported on the main frame by a carriage support assembly. The carriage support assembly includes a rotating hub affixed to the carriage that is rotatably supported by a pair of bearing collars. A hydraulic piston is provided to rotate the hub within the bearing collars, thereby rotating the carriage and arbor cuttling blade within a plae defined by the arbor cutting blade. The carriage support assembly further includes a back plate and vertical support beams to which the bearing collars are mounted. A tilting mechanism is provided to tilt the carriage support assembly, carriage and arbor cutting blade relative to the main frame such that the carriage and arbor cutting blade swings within a vertical plane perpendicular to the main from, so that the arbor cutting blade can be tilted from a first upright position for making horizontal cuts in the stone, to a second horizontal position for making vertical cuts in the stone.
