Abstract
A stone cutting device including a continuous flexible cutting belt for cutting a slot in stone which is in the ground. 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.
Claims19
A device for cutting a slot in stone comprising:
- a main frame;
- a jib movably mounted to said frame;
- a pair of spaced apart and aligned sheaves being rotatably mounted and with at least one of said sheaves having lateral width and being mounted to said jib;
- means on said frame and operably associated with said sheaves being operable to rotate same;
- and
- a continuous flexible belt with a top and opposite sides and extending around and in driven engagement by said sheaves, said belt including a plurality of spaced apart abrasive cutting strips extending across said top and sides of said belt and being flush therewith, said sides defining the width of said belt which is sized greater than said lateral width allowing said one sheave to pass through a slot cut by said belt as said jib moves said belt through said slot.
A stone cutting belt comprising:
- a flexible and continuous main body with length having a top surface, a pair of opposite side surfaces and a bottom surface, said bottom surface configured to be drivenly engaged by a sheave, said side surfaces spaced apart to be positioned outwardly of said sheave;
- a flexible elongated member extending through said main body along the length thereof and positioned between said side surfaces providing belt strength;
- and
- a plurality of stone cutting elements mounted to said main body and spaced along the length thereof, each element extending across said top surface and opposite side surfaces and being flush therewith, said elements cutting a slot in stone as the belt and sheave pass therethrough.
A stone cutting belt comprising:
- a flexible and continuous main body with length having a top surface, a pair of opposite side surfaces and a bottom surface, said belt having on its bottom surface a bottom truncated V-shaped projection extending along the length of said belt to be drivenly engaged by a sheave, said side surfaces spaced apart to be positioned outwardly of said sheave;
- a flexible elongated member extending through said main body along the length thereof and positioned between said side surfaces providing belt strength;
- and
- a plurality of stone cutting elements mounted to said main body and spaced along the length thereof, each element extending entirely across said top surface and opposite side surfaces and extending along only the outer portions of said bottom surface adjacent said side surfaces, said elements being mounted flush along each surface, the extension of each element along the outer portions of said bottom surface extending outwardly of said sheave.
