A stone slab saw. A continuous flexible belt is drivingly mounted to a plurality of sheaves rotatably mounted to a frame. A motor belt combination is operable to drive one of the sheaves and move the belt. The frame is vertically movable by a pair of racks and pinions driven by a motor. The belt includes a plurality of abrasive pad holders mounted thereto with each holder including an abrasive pad having an outwardly facing abrasive surface. A guide bar mounted to the frame is in tension guiding the belt along a straight path and providing a rigid backing as the belt is driven and lowered through the block of stone cutting a slab therefrom.

DETAILED DESCRIPTION One embodiment of the present invention is: a device for cutting a block of stone into slabs comprising a main frame and a continuous flexible belt movably mounted to the main frame and including an inwardly facing surface extending around the main frame.
The belt further including an outwardly facing abrasive surface extending in a plane laterally across the belt for engaging and cutting a block of stone.
A first driver is mounted to the main frame and is engaged with the belt for continuously moving the belt across the block of stone in a single direction.
A guide on the main frame includes opposite end portions with a downwardly opening recess extending therebetween complementarily receiving the inwardly facing surface guiding the belt as the belt is moved by the driver in the single direction.
The guide is in a state of tension providing a straight and rigid backing for the belt.
A second driver connected to the main frame is operable to force the main frame with the guide downwardly backing the belt so the abrasive surface cuts a slot into the block of stone forming a slab.
It is an object of the present invention to provide a new and improved device for cutting a free standing block of stone into slabs.
An additional object of the present invention is to provide a device for quickly cutting a block of stone.
An additional object of the present invention is to provide a saw for cutting a straight slot through stone.
Related object and advantages of the present invention will be apparent from the following description.
