The M. SAULT is a beautifully geared machine with a hand-guided paring knife. The operator of the M. SAULT cranks the gears while using a hand-guided paring arm to peel the apple. Once the apple is pared a spring lever is used to release the fork mechanism which can be rotated clockwise 90 degrees so as to position the fork and apple next to the slicer. The left hand can be used to rotate the small fork gear while the right hand cranks the wooden handle to slice the apple.
The parer is marked M. SAULT MANUFACTURER NEW HAVEN, CT on the wood frame and PATENTED DEC. 4, 1855 on the top metal piece that helps guide and lock in the fork gear. This video and the one below are presented courtesy of Jared Silbersher.
