Robert Pittis Scott (1852-1918) was granted letters patent for a lathe parer on August 14, 1883. A second patent was granted to R. P. Scott on the same day for a turntable parer designed with a rack gear that carried a coring and slicing blade.
The lathe parer based upon Scott's patent was sold as the Oriole. Scott's lathe parer uses a "worm-edged concentric disc" and rack to move a rotating apple past a paring knife and a coring and slicing blade. As the threaded disc is rotated it advances through the teeth of the rack. Once the apple is pared, cored and sliced, a small space in the threads of the disc allow it to clear the rack and be easily pulled back to starting postion.
When paring with the Oriole it is important to rotate the crank at a regular, patient pace, without applying forward pressure. The space in the threads designed to clear the rack when pulling the crank back after paring can allow the disc to get misaligned with the rack if too much forward pressure is applied during the paring process.
Some examples of this parer have the two August 14, 1883 patent dates embossed on the frame.
