Relatively large blocks of granite and other stone, weighing several tons or more, are conveyed into a guillotine type cutting machine and are quickly gauged and stopped in an aligned position to cutting chisels by means of a rigidly reinforced gauging stop mechanism. The gauging stop mechanism is uniquely combined with chisel adjusting mechanism of the guillotine machine so that very large bearing surfaces are provided for the stop mechanism to withstand heavy impact forces of a moving block. The gauging stop mechanism is movable downwardly into a gauging position for contacting an upper leading edge of a block of stone at points in front of the cutting chisels when the cutting chisels are raised. With the gauging mechanism in its lowered position, the cutting chisels are locked out of operation. The stop mechanism when moved upwardly releases the cutting chisels and simultaneously provide a cleared space into which cut-off sections of stone may be displaced forwardly of the cutting chisels without damage to the stop mechanism. The gauging stop mechanism further includes a set of detachable spacer plates of different sizes which are interchangeable to vary their spaced relationship to the upper set of cutting chisels.
