Patent ID: 7377275

Claim:
An imitation stone cutter, comprising: a lower blade mount assembly, said assembly including means to support an imitation stone while the stone is being cut; a lower blade mountable to the lower blade mount assembly and having a top cutting edge, said edge having a canted, asymmetrical wedge shape in transverse, vertical cross-section; a vertically-elongated standard having a lower end and an opposite upper end, said lower end being rigidly attached to the lower blade mount assembly; an upper blade having a bottom cutting edge, said cutting edge having an asymmetrical wedge shape in transverse, vertical cross-section that is canted opposite to the cant of the cutting edge of the lower blade, and said cutting edge being aligned in a common cutting plane with the cutting edge of the lower blade; an upper blade mount assembly slidably mounted to the standard for vertical movement between a first, upper position and a second, lower cutting position, and adapted to receive and hold the upper blade above and parallel to the lower blade; an actuator mount assembly attached to the standard above the upper blade mount assembly, wherein said actuator mount assembly has a tubular rear end portion attached to the standard and an opposite, front end portion that terminates in a clevis, and the front end portion of the upper blade mount assembly has a convex top surface; and actuator means attached to the actuator mount assembly for forcing the upper blade mount assembly down from said first, upper position to said second, lower, cutting position, wherein said actuator means includes a transversely-apertured cam plate pivotably attached by a clevis pin to the clevis for rotation in a vertical plane, said cam plate having a convex bottom cam surface, a front portion of said cam surface extending farther away from the clevis pin than a rear portion thereof, and an elongated handle that extends forwardly from the cam plate; whereby, downward movement of the handle causes the cam surface of the cam plate to slide against the convex top surface of the front end portion of the upper blade mount assembly, forcing said upper blade mount assembly downward for cutting, and, thereafter, raising the handle returns the upper blade mount assembly to the first, upper position.
