Union

The Union made by D.H. Whittemore is another return that reverses direction while in gear. The hand-driven gear and the central gear, which meshes with the paring arm gear, have teeth on their edges and modified helical-like teeth across their inner surface. All of the gears stay locked together and the shapes of the modifed teeth allow the paring arm to smoothly reverse direction. Apples can be pared in both directions. This parer is marked THE UNION and D.H. WHITTEMORE WORCESTER MA PAT. NOV. 11, 1866. This wonderful design went through several modifications and was further developed by Landers, Frary, & Clark.
