a stone cutting device including a continuous flexible cutting belt for cutting a slot in stone which is in the round . the device includes a main frame , a jib pivotally mounted to the main frame , aligned sheaves rotatably mounted to the main frame and jib , a continuous flexible cutting belt extending around and in driven engagement by the sheaves , and a means to rotate at least one of the sheaves . the continuous flexible cutting belt includes a plurality of spaced apart abrasive cutting elements extending across the top and sides of the belt . the cutting elements are flush with the remainder of the top and side surfaces of the belt which includes a molded - in - place resilient material . belt strength is provided by a flexible cable extending through the length of the belt . the preferred embodiment of the invention includes a groove on the top and bottom edges of the jib and outlet means opening in the groove allowing water to be emitted between the groove and the belt to provide lubrication and reduced vibration as the belt passes through the groove . during operation , the water thus emitted from the jib passes outside the groove and into the cut slot in the stone and washes away stone cuttings for improved operation of the device .
