Abstract
A wooden stake sharpening machine moves a conical cutting head along a linear path into engagement with a clamped wooden stake blank to affect sharpening thereof. A walking beam conveying apparatus moves a wooden stake blank into position from a supply bin where a clamping apparatus holds the stake blank in place while the cutting head moves onto the stake to form a point thereon. The drive mechanism moves the conveyor in coordination with the linear movement of the cutting apparatus, which trips a switch to actuate the clamping mechanism as the cutting head moves toward engagement with the stake blank. The conveyor then moves the sharpened stake toward a collection area while moving another stake blank into position for sharpening as the cutting apparatus is retracted away from the stake, thus providing an automated stake sharpening machine with a minimal number of moving parts.
